The term "and/or" as used herein includes any and all combinations of one or more of the associated listed items.
As shown in fig. 1, in order to solve the above technical problem, according to a first aspect of the present disclosure, there is provided a life test method of a waste water valve, the life test method of the waste water valve including the steps of:
s100, acquiring a first concentration, and configuring the test water according to the first concentration; wherein the first concentration is the actual concentration of the water body in the original water tank of the water purifier;
in this embodiment, taking the table water purifier as an example, the actual concentration of the water body in the raw water tank of the table water inlet device is obtained, and the actual concentration is set to be the first concentration, so that the water body in the raw water tank is simulated for testing according to the test water configured according to the first concentration, and the accuracy of the test result is ensured. Wherein the dissolved substance concentration in the water can be measured by a concentration measuring means, such as a TDS meter (total dissolved solids meter). In testing the quality of water in a water purifier, a TDS meter may be used to measure the concentration of solid suspended matter in the water.
Illustratively, a first concentration of test water can be obtained by adjusting the ratio of water to powder having the same composition as the solid suspension in the raw water tank. The specific configuration method is not described herein, and is common knowledge of those skilled in the art.
S200, acquiring a set target pressure, sequentially introducing the test water into a scale inhibition filter element and a waste water valve, enabling the test water to flow through the waste water valve at the set target pressure, and acquiring the initial flow of the waste water valve 106; wherein the test water is recycled, and the scale inhibitor of the scale inhibition filter element 112 has a mass not less than that of the scale inhibitor in the table water purifier;
in this embodiment, the actual water pressure of the original water tank of the table-board water purifier is obtained, the actual water pressure is set to be the set target pressure, and after the test water flows through the scale inhibition filter element, the test water is discharged into the waste water valve 106 by adjusting the water pressure of the test water, so that the actual use environment of the waste water valve 106 is simulated, and the accuracy of the test is ensured.
For example, the water pressure in the raw water tank of the table water purifier can be obtained through a water pressure sensor. Likewise, the water pressure of the test water discharged into the waste valve 106 can be obtained by the water pressure sensor; alternatively, the pressure of the test water discharged into the waste valve 106 is displayed by the pressure gauge 105. There is no particular limitation herein, as long as the apparatus can obtain the water pressure in the raw water tank or the water pressure of the test water entering the waste valve 106.
Obviously, by recycling the test water and adding the scale inhibiting filter cartridge 112, and adding the scale inhibitor to the scale inhibiting filter cartridge 112 with a mass not less than the mass of the scale inhibitor in the scale inhibiting filter cartridge 112 of the original tank, it is not necessary to match the corresponding counter top water purifier and scale inhibiting filter cartridge 112 for actual testing of the lifetime of the waste water valve 106.
Wherein the test water is recycled, that is, the test water is reused to circulate the test water to the scale inhibiting filter cartridge 112 and the waste water valve 106.
Illustratively, the test water discharged from the scale inhibiting filter cartridge 112 and the waste water valve 106 is re-discharged into the scale inhibiting filter cartridge 112 and the waste water valve 106 for recycling. The specific arrangement is not particularly limited herein, and reference may be made to the following structural cooperation arrangement with respect to the water inlet tub 103 and the water storage tub 111.
It is easy to understand that the scale inhibition filter element can reduce the precipitation generated by the change of the ion solubility product in the solution caused by the change of the external conditions of the prepared test water, and further reduce the influence of the fluctuation of the concentration of the solution on experimental test data. In short, the scale inhibition filter element is not blocked, and the reason is that: the standard for judging the service life of the scale inhibition filter element is that the scale inhibition filter element does not release scale inhibition factors or releases scale inhibition factors too slowly, and whether the flow is changed or blocked or not.
Illustratively, the scale inhibitor of the scale inhibiting filter cartridge 112 has a mass equal to the mass of scale inhibitor in the counter top water purifier; alternatively, the scale inhibitor of the scale inhibiting filter cartridge 112 has a mass greater than the mass of scale inhibitor in the counter top water purifier. Of course, excessive scale inhibitor can be added into the scale inhibition filter element within the service life range of the scale inhibition filter element so as to ensure that the test is normally carried out and improve the accuracy of the test result, which also belongs to the conventional technical means of the person skilled in the art.
In other words, the scale inhibitor in the scale inhibition filter element is excessively arranged, so that the scale inhibition filter element can normally and effectively operate in the whole life test process of the waste water valve. The scale inhibition filter element increases the solubility of calcium and magnesium ions to reduce the precipitation of the calcium and magnesium ions, and the scale inhibition filter element is added in the service life process of the test waste water valve and the test purpose cannot interfere with each other.
S300, acquiring a set target flow, and if the initial flow accords with the set target flow, keeping the test water to be sequentially introduced into the scale inhibition filter core 112 and the waste water valve 106;
in this embodiment, when the test water is initially discharged into the waste water valve 106, the initial flow rate of the waste water valve 106 is compared with the set target flow rate, and the test water is continuously kept to be continuously introduced into the waste water valve 106 only when the comparison result meets the set requirement. That is, the above-described operation is performed when the initial flow rate meets the set target flow rate. The target flow rate is set to a range of values, and the initial flow rate is in accordance with the target flow rate.
Of course, if the initial flow rate does not meet the set target flow rate, which indicates that there is a problem with the testing system of the waste water valve 106, the testing system of the waste water valve 106 may be stopped, and the tester needs to replace or reset and overhaul the equipment. Obviously, invalid tests can be avoided by the above operations.
S400, acquiring a set target water quantity, and acquiring the actual flow of the wastewater valve 106 and the actual water quantity flowing through the wastewater valve 106 when the actual water quantity flowing through the wastewater valve 106 of the test water meets the set target water quantity.
In this embodiment, a plurality of set target water volumes, such as a first set target water volume, a second set target water volume, a third set target water volume, etc., are set in a test system of the wastewater valve 106 of the mesa water purifier, and when the actual water volume flowing through the wastewater valve 106 meets the first set target water volume, a first actual flow of the wastewater valve 106 and a first actual water volume at the moment are acquired and recorded, and a corresponding relationship exists between the two; similarly, when the actual amount of water flowing through the waste water valve 106 meets the second set target amount of water, the second actual flow rate of the waste water valve 106 and the second actual amount of water at this time are acquired and recorded, and there is a correspondence between the two. Thus, the actual water quantity and the corresponding actual flow rate, i.e. the test result, can be displayed after the test. It is easy to understand that the waste water valve 106 has a design standard with a lower limit flow rate of the waste water valve 106, that is, if the actual flow rate of the waste water valve 106 is lower than the lower limit flow rate, the waste water valve 106 is in an unusable state or a scrapped state, and further, the service life of the waste water valve 106 can be obtained by comparing the actual flow rate with the lower limit flow rate.
By applying the life test method of the waste water valve, the water body concentration in the raw water tank of the table water purifier when the waste water valve 106 is actually used is obtained, the water body concentration is set to be the first concentration, the test water with the first concentration is configured, the water pressure discharged into the waste water valve 106 is limited to be the actual water pressure of the operation of the table water purifier and is set to be the set target pressure, the test water is discharged into the waste water valve 106 according to the set target pressure, and the scale inhibition filter core 112 is arranged to be matched with the recycled test water, so that the life test can be performed by simulating the actual working condition of the waste water valve 106. And, do not need to match the corresponding mesa water purifier and scale inhibition filter core 112 for actual testing of the lifetime of the waste water valve 106, thereby solving the problem of testing the lifetime of the waste water valve 106 and saving cost. In addition, through recycling the clean water, the service life test of the waste water valve 106 can be completed by only using the test water which is configured at one time under the condition of no abnormality in the test process, the actual flow of the waste water valve 106 and the actual water quantity of the test water which correspondingly flows through the waste water valve 106 can be recorded, the actual flow state of the waste water valve 106 can be judged according to the actual water quantity, and the service life of the waste water valve 106 can be obtained by comparing the actual flow of the waste water valve 106 with the lower limiting flow of the design parameters of the waste water valve 106.
On the basis of the above embodiment, in step S100, obtaining the first concentration includes obtaining the first concentration of the test water based on the second concentration of the raw water in the raw water tank and the third concentration of the remaining wastewater in the raw water tank that enter the counter water purifier.
That is, by obtaining the second concentration of the inflow water of the raw water tank (i.e., raw water) and the third concentration of the remaining wastewater, the first concentration is calculated according to the second concentration and the third concentration, and the test water is further configured to simulate the real use scene of the wastewater valve 106.
Illustratively, the configured test water is stored in the water inlet bucket 103; wherein, the powder and water are added into the water inlet barrel 103 and stirred uniformly, so that the test water can be configured.
On the basis of the above embodiment, the obtaining the first concentration of the test water according to the second concentration of the raw water in the raw water tank and the third concentration of the remaining wastewater in the raw water tank of the table water purifier includes:
and setting the average value of the second concentration and the third concentration as the first concentration according to the second concentration of raw water entering a raw water tank of the table water purifier and the third concentration of residual wastewater in the raw water tank so as to obtain the first concentration of test water.
That is, the first concentration c= (cf+cw)/2 of the test water is calculated from the TDS concentration (i.e., second concentration) Cf of the actual intake water of the table water purifier to be measured and the concentration Cw of the waste water remaining in the original tank of the table water purifier.
On the basis of the above embodiment, obtaining the set target flow includes:
and according to the upper flow limit value and the lower flow limit value of the waste water valve 106, setting the flow range between the upper flow limit value and the lower flow limit value as the set target flow to obtain the set target flow.
That is, when the actual flow rate of the waste water valve 106 is between the flow rate upper limit value and the flow rate lower limit value, it means that the waste water valve 106 is in normal operation; if the actual flow rate of the waste water valve 106 is greater than the upper flow rate limit or the actual flow rate of the waste water valve 106 is less than the lower flow rate limit, it means that the waste water valve 106 is in an abnormal state and effective test cannot be performed.
The upper and lower flow limit values of the waste water valve 106 are designed product parameters of the waste water valve 106, which are fixed values.
On the basis of the above embodiment, acquiring the set target pressure includes:
and setting the actual working pressure of the table water purifier to the set target pressure so as to acquire the set target pressure.
That is, in order to simulate the actual use scenario of the waste water valve 106, the water pressure of the test water discharged into the waste water valve 106 is set to the actual working pressure of the table water purifier, and the accuracy of the result of testing the life of the waste water valve 106 is ensured.
On the basis of the above embodiment, the service life testing method of the waste water valve further includes:
if the initial flow rate does not meet the set target flow rate, stopping sequentially introducing the test water into the scale inhibition filter core 112 and the waste water valve 106 and alarming.
That is, if the actual flow rate of the waste water valve 106 is greater than the upper flow rate limit or the actual flow rate of the waste water valve 106 is less than the lower flow rate limit, it means that the waste water valve 106 is in an abnormal state, and effective test cannot be performed. At this time, the service life test system 100 of the waste water valve is stopped, and a tester performs replacement of the waste water valve or reset and maintenance of the equipment.
On the basis of the embodiment, the water for testing is recycled, comprising:
the test water in the water inlet barrel 103 is sequentially discharged into the scale inhibition filter core 112 and the waste water valve 106 through the first water pump 104, and the test water discharged from the waste water valve 106 is collected through the water storage barrel 111; wherein the test water in the water storage tub 111 is discharged into the water inlet tub 103 through the second water pump 110.
In this embodiment, the first water pump 104 discharges the test water in the water inlet barrel 103 into the scale inhibition filter element 112 and the waste water valve 106 at the actual working pressure, the test water discharged from the waste water valve 106 flows into the water storage barrel 111 to collect the test water, and when the liquid level in the water inlet barrel 103 is reduced to the minimum liquid level, the first water pump 104 stops running, and the test water in the water storage barrel 111 is discharged into the water inlet barrel 103 again through the second water pump 110 to realize the backflow of the test water. When the liquid level in the water inlet tank 103 rises to the highest level, the second water pump 110 stops operating, and the first water pump 104 is restarted to continue the life test of the waste valve 106. Thus, the test water can be recycled.
Because the existing valve testing method has no scheme aiming at a waste water backflow system, the service life of the valve needs to be tested under an actual system in practice if the service life of the valve needs to be tested. In the field of water purification, according to the water efficiency test standard water purifier, the water production quantity is 2000-4000L < 1 >, and in combination with a certain waste water ratio, the test water used for actually testing a waste water valve is 4444-6153L < 2 >, and the test reagent is about 3.581-4.958kg < 3 >. By adopting the mode of this embodiment to test, only 3-6L 4 of test water is needed, and the test agent is about 0.002-0.004kg 5, so as to practically meet the requirements of energy saving and environmental protection.
The auxiliary water consumption and the medicament consumption are calculated and explained:
[1] in order to specify the rated total water purifying amount in the water efficiency grade according to the water efficiency limit value and the water efficiency grade of the reverse osmosis water purifier of 34914-2021, the water efficiency of 3 grade corresponds to 2000L, the water efficiency of 2 grade corresponds to 3000L, and the water efficiency of 1 grade corresponds to 4000L;
[2] the water efficiency limit value and the water efficiency grade of the reverse osmosis water purifier are set according to the specification of 34914-2021:
(1) the water efficiency rating of the 3-level water is 2000L, the water yield is 45 percent, namely at least 2000/0.45= 4444.44L of water is needed;
(2) the rated water purification amount of the 2-level water efficiency is 3000L, the water yield is 55 percent, namely at least 3000/0.55= 5454.55L of water is needed;
(3) the rated water purifying amount of the 1-level water efficiency is 4000L, the water yield is 65 percent, namely at least 4000/0.65= 6153.85L of water is needed.
[3] The water efficiency limit value and the water efficiency grade of the reverse osmosis water purifier are set according to the specification of 34914-2021:
100L test water formula: 25.1 g calcium chloride dihydrate, 21.05 g magnesium sulfate heptahydrate, 7.90 g sodium chloride, 26.53 g sodium bicarbonate, 25.1+21.05+7.90+26.53= 80.58 g;
(1) for test water 4444.44L, the required dosage is 80.58 x 4444.44/100= 3581.32 g;
(2) for test water 6153.85L, the dosage is 80.58×6153.85/100= 4958.77 g.
[4] The capacity of the original water tank of the common table-board water purifier is about 3-6L;
[5] To calculate the volume as described in [4]
(1) For test water 3L, the required dosage is 80.58 x 3/100=2.42 g;
(2) for test water 6L, the required dosage is 80.58 x 6/100=4.83 g.
On the basis of the above embodiment, the service life testing method of the waste water valve further includes:
acquiring a first set target starting time of the first water pump 104 and a first actual starting time of the first water pump 104;
if the first actual starting time is longer than the first set target starting time, stopping sequentially introducing test water into the scale inhibition filter element 112 and the waste water valve 106 and alarming;
since the water inlet bucket 103 has the limitation of the minimum liquid level and the maximum liquid level, when the first water pump 104 operates normally, a fixed operation time, that is, a first set target start time, is necessarily formed. Briefly, the first set target start-up time is: the first water pump 104 pumps the test water in the water inlet tub 103 into the water storage tub 111 and the time taken for the test water in the water inlet tub 103 to drop from the highest level to the lowest level. Obviously, if the single operation time of the first water pump 104 is too long, that is, the first actual start time is longer than the first set target start time, it represents that the first water pump 104 is abnormal or the water inlet barrel 103 is abnormal, and the life test system 100 needs to be controlled to stop operation at this time, and the tester checks.
Based on the above embodiment, a second set target start time of the second water pump 110 and a second actual start time of the second water pump 110 are obtained;
if the second actual starting time is longer than the second set target starting time, stopping sequentially introducing the test water into the scale inhibition filter element 112 and the waste water valve 106 and alarming;
similarly, since the water inlet tank 103 has the limitation of the minimum liquid level and the maximum liquid level, the second water pump 110 must form a fixed operation time, that is, the second set target start time, when operating normally. Briefly, the second set target start-up time is: the second water pump 110 pumps the test water in the water storage tub 111 into the water inlet tub 103 and the time taken for the level of the test water in the water inlet tub 103 to rise from the lowest level to the highest level. Obviously, if the single operation time of the second water pump 110 is too long, that is, the second actual start time is longer than the second set target start time, it represents that the second water pump 110 is abnormal or the water inlet barrel 103 is abnormal, and the life test system 100 needs to be controlled to stop operation at this time, and the tester checks.
It should be noted that, the first actual start-up time and the second actual start-up time may be measured by a timer mechanism, such as a timer.
On the basis of the above embodiment, obtaining the first set target start-up time of the first water pump 104 includes:
acquiring the highest liquid level and the lowest liquid level of the water inlet barrel 103;
acquiring a first time taken by the first water pump to pump the test water in the water inlet barrel 103 into the water storage barrel 111 and to enable the liquid level of the water inlet barrel 103 to drop from the highest liquid level to the lowest liquid level, wherein the first time is the first set target starting time;
correspondingly, the obtaining the second set target start time of the second water pump 110 includes:
acquiring the highest liquid level and the lowest liquid level of the water inlet barrel 103;
and obtaining a second time consumed by the second water pump to pump the test water in the water storage barrel 111 into the water inlet barrel 103 and enable the liquid level of the test water in the water inlet barrel 103 to rise from the lowest liquid level to the highest liquid level, wherein the second time is the second set target starting time.
For example, a liquid level sensor may be disposed in the water inlet tub 103 to detect the liquid level of the water inlet tub 103 in real time, and the liquid level sensor and the controller are electrically connected with the first water pump 104 and the second water pump 110, respectively, so that the single operation time of the first water pump 104 and the second water pump 110 can be precisely controlled. The liquid level sensor can be a single-flange static pressure/double-flange differential pressure liquid level transmitter, a floating ball type liquid level transmitter, a magnetic liquid level transmitter, a throw-in type liquid level transmitter, an electric inner floating ball type liquid level transmitter, an electric float type liquid level transmitter, a capacitive liquid level transmitter, a magnetostrictive liquid level transmitter, a servo liquid level transmitter, an ultrasonic liquid level transmitter, a radar liquid level transmitter and the like, and is not particularly limited herein; the controller may be a switch controller, a PLC programmable controller, or the like, and is not particularly limited herein, as long as the controller can control the start and stop of the first water pump 104 or the second water pump 110 according to the liquid level signal transmitted from the liquid level sensor.
In one embodiment, as shown in fig. 2, a life test system 100 of a waste water valve is provided, wherein the life test system 100 of the waste water valve comprises a water inlet barrel 103, a water storage barrel 111, a first water pump 104, a scale inhibition filter element 112, a pressure detection mechanism, a waste water valve 106, a flow detection mechanism, a water metering mechanism and a second water pump 110; wherein the water inlet barrel 103 can store the test water; the water storage tub 111 is capable of storing the test water; the water inlet barrel 103, the first water pump 104, the scale inhibition filter element 112, the pressure detection mechanism, the waste water valve 106, the flow detection mechanism, the water metering mechanism and the water storage barrel 111 are connected in sequence; the water storage barrel 111 is also connected with the water inlet barrel 103 through a second water pump 110.
The pressure detection mechanism may be a water pressure sensor or a pressure gauge 105; the flow sensing mechanism may be a flow meter 107; the water metering mechanism may be a water meter 108.
Obviously, the water inlet barrel 103, the first water pump 104, the scale inhibition filter core 112, the pressure detection mechanism, the waste water valve 106, the flow detection mechanism, the water metering mechanism, the water storage barrel 111 and the second water pump 110 form a circulation loop, so that the test water can circularly flow in the circulation loop to simulate the actual use scene of the waste water valve 106.
On the basis of the above embodiment, the first water pump 104, the pressure detection mechanism, the flow detection mechanism, the water amount metering mechanism, and the second water pump 110 are all electrically connected to the controller, whereby the operations of the respective components can be controlled by the controller.
Based on the above embodiment, the service life testing system 100 of the waste water valve further includes:
the first water pump 104 is further connected to the water storage tub 111 through the flow rate adjusting valve, so that a portion of the test water discharged from the first water pump 104 enters the water storage tub 111 through the flow rate adjusting valve.
I.e. the adjustment of the water pressure of the test water entering the waste valve 106 is achieved by the flow regulating valve in combination with the first water pump 104. The first water pump 104 can be prevented from being pressed down by the flow regulating valve, so that damage is caused. Likewise, the flow regulating valve may be a flow electromagnetic regulating valve electrically connected to the controller so that the opening of the flow regulating valve can be automatically lifted by the controller according to the detected water pressure of the pressure detecting mechanism until the detected water pressure flowing through the waste water valve meets the set target pressure.
Based on the above embodiment, the service life testing system 100 of the waste water valve further includes:
The liquid level detection mechanism is electrically connected with the first water pump 104, and is used for acquiring the liquid level in the water inlet barrel 103 and controlling the first water pump 104 to start and stop according to the liquid level.
That is, the liquid level of the water inlet tub 103 can be obtained in real time through the liquid level detection mechanism to control the start and stop of the first water pump 104 and the second water pump 110.
Based on the above embodiment, the liquid level detection mechanism includes a controller and a liquid level sensor, and the liquid level sensor is electrically connected to the first water pump 104 and the second water pump 110 through the controller.
Illustratively, the liquid level sensor includes a pair of floating ball type liquid level sensors disposed in the water inlet tub, the pair of floating ball type liquid level sensors being respectively installed at different heights in the water inlet tub 103 to form an upper floating ball type liquid level sensor 101 and a lower floating ball type liquid level sensor 102, the liquid levels measured by the upper floating ball type liquid level sensor 101 and the lower floating ball type liquid level sensor 102 respectively corresponding to the highest liquid level and the lowest liquid level of the water inlet tub 103.
For ease of understanding, the following test steps are provided that are adapted to the test system:
step 1: inputting the opening time T(s) of the waste water valve 106 according to the actual flushing time of the table water purifier to be tested;
For example, the simulation of a real machine program, in actual use, to prevent the waste valve from clogging, will initiate a waste valve flushing program.
It is easy to understand that the waste water valve has two gear holes, the small hole with smaller diameter is provided when the electricity is not applied, under the condition that the inflow water flow is 4L/min, the water flow is only allowed to pass through as the aperture of the small hole is too small to completely pass through when the water flows, so the rest water enters the filtering piece and the outflow water flow is 3L/min, thereby playing the role of purification; the small hole is easy to be blocked by pollutants, so that a large gear is selected during flushing, the small hole is converted into the large hole, and the pollutants are discharged through the large hole, so that the service life of the waste water valve can be prolonged; however, even if flushing exists, when the pollutant is accumulated to a certain degree, the large holes are blocked, or the pollutant cannot be discharged from the large holes, namely, the flow rate does not meet the design requirement, so that the service life of the waste water valve is ended.
Step 2: calculating the concentration C= (Cf+Cw)/2 of test water in a water inlet barrel according to the actual water inlet concentration (TDS) Cf and the residual wastewater concentration Cw of the table water purifier to be tested, obtaining a first concentration, preparing the test water in the water inlet barrel 103, and adding a scale inhibitor with the quality identical to that in the table water purifier to be tested into a scale inhibition filter element 112; wherein the actual water inlet concentration is the second concentration of raw water, and the residual wastewater concentration is the third concentration.
Step 3: the tester inputs the actual working pressure P of the water purifier on the table surface to be tested of the system, namely the set target pressure;
step 4: the tester inputs the set water quantity V corresponding to the life taking point 1 、V 2 ……V n Wherein n is a natural number, and n is more than or equal to 2;
exemplary, life test procedure:
a. waste water valve life definition: after 4000L of test water, the water is not blocked;
b. occlusion definition: the actual flow of the waste water valve is smaller than the lower limit value of the flow;
c. the testing process comprises the following steps: taking 5 points in service life, namely setting water volumes to be 0, 800, 1600, 2400, 3200 and 4000L respectively, and recording the actual flow of a waste water valve after the test water with corresponding volume flows through the waste water valve;
the purpose is as follows: the performance of the waste water valve at each stage is tested to determine whether the performance is affected, for example 4000L is defined when the service life of the waste water valve is designed, if the service life process is not tested, and the service life 4000L is finished, and when the waste water valve is blocked, the waste water valve cannot be judged when the waste water valve is blocked. For example, if the actual water volume flowing through the waste valve is 3200L, the actual flow through the waste valve is acceptable, and if the actual water volume flowing through the waste valve is 4000L, the actual flow through the waste valve is unacceptable, the conclusion is that the waste valve life is 3200L.
Step 5: the tester inputs the upper limit value Q of the flow rate of the waste water valve 106 h As a system abnormality determination, the flow lower limit value Q L As an end-of-life determination, the actual flow Q during the lifetime of the waste valve 106 should satisfy Q h ＞Q＞Q L ；
Step 6: the tester inputs the upper limit T of the starting time of the first water pump 104 1 (i.e., the first set target start time), the upper limit T of the start time of the second water pump 110 2 (i.e., a second set target start-up time);
step 7: starting a test system after parameter input is completed;
step 8: the waste water valve 106 is opened for time T(s), the first water pump 104 is started, and the test system performs a waste water valve 106 flushing stage;
step 9: after the flushing of the waste water valve 106 is completed, the system controls the waste water valve 106 to be closed, the first water pump 104 is opened, and the flow regulating electromagnetic valve 109 is opened to a specific opening degree, so that the pressure gauge 105 reaches the set target pressure P; at this time, the waste water valve 106 is opened, and the test water in the water inlet barrel 103 flows into the water storage barrel 111 through two channels of the flow rate adjusting electromagnetic valve 109 and the waste water valve 106;
the whole system in the water purifier system has a working pressure, and a specific scale inhibition filter element is not involved in the test system, so that the working pressure is different from that of a real machine, and a flow regulating electromagnetic valve is needed to control the flow so as to indirectly regulate the pressure of the test system to be consistent with that of the real machine, and the test reliability is ensured.
Step 10: the flowmeter 107 records the initial flow rate of the waste valve 106 at this time as an initial flow rate Q 0 And judging if Q 0 ＞Q h Or Q 0 ＜Q L Reporting errors, and requiring a tester to replace or reset and overhaul the equipment; if Q h ＞Q 0 ＞Q L The system controls the water meter 108 to begin recording the actual water volume V 0 The test system continues to operate;
by way of example, and with the above-described life test method, the present test system determines that the wastewater valve life is such that after a certain volume of test water has passed through the wastewater valve, no blockage that cannot be recovered by flushing will occur, and that the flow rate is in accordance with the design value.
The real-time monitoring of the actual flow and the actual water quantity of the waste water valve is too huge in data quantity, which is unfavorable for reading judgment, for example, an engineer can see a specific volume to measure the flow of the waste water valve, and manpower is wasted.
In summary, the solution is: setting the set water quantity (0-800-1600-2400-3200-4000L) corresponding to the service life taking point in advance, and judging the relation between the actual water quantity of the test water flowing through the waste water valve and the set water quantity when the test system runs out of one tank of water;
if the actual water quantity is 750L, the system judges that the water quantity exceeds 0L, the data exists in 0L, the water quantity is less than 800L, and the water quantity is 800L, and if the water quantity is not less than 800L, the test is continued, and the data is not recorded; when the actual water amount is 803L, the system judges that the water amount exceeds 800L, and 800L sections do not have data, the flow data of 800L sections are recorded, and whether the service life of the waste water valve is finished is judged.
Step 11: when the water level in the water inlet barrel 103 drops to the lowest liquid level, the controller controls the first water pump 104 to be closed, the second water pump 110 to be opened, and test water in the water storage barrel 111 is pumped into the water inlet barrel 103 through the second water pump 110;
step 12: when the water level of the water inlet barrel rises to the highest liquid level, the controller controls the second water pump 110 to be turned off, and at the moment, a period is ended;
step 13, the system re-enters step 6 to start a second period;
step 14: after the second cycle of flushing the waste valve 106 is completed, the system reads V according to the water meter 108 t And (3) judging:
(1) if V n ＜V t -V 0 ＜V n+1 When the controller controls the flowmeter 107 to read the actual flow rate Q n The system makes a determination if Q n ＞Q h Or Q n ＜Q L Reporting errors, and requiring a tester to replace or reset and overhaul the equipment; if Q h ＞Q n ＞Q L， The system controls the water meter 108 to begin recording the actual water volume V n The system continues to operate;
(2) if V n ＞V t -V 0 And V is t -V 0 ＞V n-1 When the system continues to operate.
Step 15: when the system determines that the water meter 108 is reading V n ＜V t -V 0 ＜V n+1 At this time, the system records the meter 107 reading Q n The test is completed, and the system finally displays the corresponding actual water quantity V 1 、V 2 ……V n And corresponding test result Q 1 、Q 2 ……Q n 。
Step 16: if the actual start time T > T of the first water pump 104 during the life test 1 Or the actual start time T > T of the second water pump 110 2 When the system is used for testing water loss or abnormality, the system is closed and alarms, and a tester performs spot inspection, water distribution, resetting or maintenance.
