The cotton strainer of tertiary filter 7-third stage PP, the pre-filtering of 1 micron, aperture, removes because activated carbon comes off generation fine particulate material.
Low-tension switch 8, when hydraulic pressure reaches preset pressure, switches on power, and machine is normally run; When cutting off the water supply, or when hydraulic pressure does not reach default, cut off the electricity supply, machine sends buzzing and reports to the police.
Entering water electromagnetic valve 9, when the power is turned on, tap water, through entering water electromagnetic valve, makes water purification machine normally water processed; Cut off the water supply after machine stops, stoping tap water to be gone over, drained by waste pipe.
High-pressure pump 15, reaches certain pressure value, to meet pressure and the traffic demand of reverse osmosis filter 2 to tap water pressurization.
Reverse osmosis filter 2, it relies on machine to pressure that tap water applies, to make in tap water moisture through reverse osmosis membrane, and the fine impurity in tap water, other objectionable impurities such as too much inorganic salt, organism, heavy metal ion, bacterium, virus, agricultural chemicals, trichloromethane refuse is completely retained down, and xenobiotic in these water and salinity are discharged by the dense water of continuous blow-down, and then obtain very clean tap water.Its aperture only has 0.0001 micron, it to the clearance of the minimum inorganic ion of particle diameter in water more than 90-96%, to the clearance (can be said in theory is 100%) more than 99.99% of the xenobiotic such as bacterium, virus.
Pressure water storage barrel 12, stores pure water, for for subsequent use.
Pyatyi strainer 18-activated charcoal filter, removing peculiar smell makes water quality glycol sweet, avoids pure water secondary pollution in pressure water storage barrel.
Pure water tap 11, takes the switch of pure water.
Waste water proportioner 17, makes concentrated waste water drain, builds the pressure through aperture current limliting, ensures the operating pressure of reverse osmosis filter.Its effect is exactly control flow, ensure constant system pressure.
Scouring electromagnetic valve 14, is controlled automatically by computer board 22, carries out high-pressure high-flow flushing to reverse osmosis filter.
Pressure detection switch a20, for detecting the variation in water pressure in the inlet channel 3 between entering water electromagnetic valve 9 and high-pressure pump 15.
Pressure detection switch b21, for detecting the variation in water pressure in the pipeline between high-pressure pump 15 and flushing pipeline 16 water-in 1.
Leak detection magnetic valve 19, for coordinating with pressure detection switch a20, pressure detection switch b21 the working condition detecting entering water electromagnetic valve 9.
Based on the leak detection system of water purification machine described above, devise a kind of leak hunting method, comprise the following steps:
1). close leak detection magnetic valve 19;
2). variation in water pressure in pressure detection switch testing pipes, and by signal transmission to computer board 22;
3). computer board 22 receives and processing signals, and judge in pipeline, whether hydraulic pressure exceeds normal value, if abnormal, computer board 22 controls alarm unit and gives the alarm.
Specifically for situations such as water clock, booster, entering water electromagnetic valve are not closed completely, its detailed process is slightly different, as described below:
For the situation-when stop moment after the full pure water of pure water mechanism of pipeline water clock, computer board 22 controls entering water electromagnetic valve 9, high-pressure pump 15 and leak detection magnetic valve 19 and closes, and under normal circumstances, the hydraulic pressure now in pipeline is stable by maintenances.Now, if there is the situation of water clock to occur, then pressure detection switch a20, pressure detection switch b21 will detect the situation that hydraulic pressure declines, and signal is sent to computer board, and computer board controls alarm unit warning reminding user after process judges.Because hydraulic pressure in water clock situation declines comparatively slow, generally needed to this leak water detdction the cost 2 hours time.When in this process, when water purification machine enters water state processed again, the leak detection programcontrol by-pass of computer board, guarantees water process priority processed.
For the situation-detect in the water purification machine Pure-water Making period of booster, by computer board 22 time variable control, within every 8 ~ 10 minutes, recurrence interval is detected, method is as follows: computer board 22 controls leak detection magnetic valve 19, high-pressure pump 15 and entering water electromagnetic valve 9 and closes simultaneously, if there is pipeline generation booster, hydraulic pressure then in pipeline will decline rapidly, pressure detection switch a20, pressure detection switch b21 send signal after situation being detected, by processing and identification after computer board 22 Received signal strength, control warning howler sends reports to the police and cuts off tap water.If pipe condition is normal, then in pipeline, hydraulic pressure is constant, and water purification machine keeps normal work.This checkout procedure continues 20 ~ 30 seconds.
Situation about being not closed completely for entering water electromagnetic valve 9-complete twin conduit water clock and pipeline burst detection and carry out this after fixing a breakdown and check.First, computer board 22 controls entering water electromagnetic valve 9 and closes, leak detection magnetic valve 19 is opened, water in pipeline is discharged by waste pipe 13, hydraulic pressure in pressure detection switch a20 and pressure detection switch b21 testing pipes by signal transmission to computer board 22, computer board 22 controls leak detection magnetic valve 19 and closes, if fruit entering water electromagnetic valve 9 is not closed completely, tap water will enter in pipeline, due to pipe sealing, hydraulic pressure in pipeline will rise gradually, finally by pressure detection switch a20, pressure detection switch b21 detects and sends signal, after computer board 22 Received signal strength, control alarm unit and send warning.The severity that this process is not closed completely depending on entering water electromagnetic valve 9, the time of cost is different.
In addition, described leak detection system can also arrange cloud server (figure does not identify), wireless communication module (figure does not identify), mobile terminal (figure does not identify) and control monitoring center's (figure does not identify), described computer board 22 is connected with cloud server by wireless communication module, mobile terminal and cloud server wireless connections, control monitoring center and be connected with cloud server; Analytical results is sent to cloud server by wireless communication module after carrying out calculation process analysis by described computer board, analytical results is sent to mobile terminal and controls monitoring center by cloud server, arrange special messenger to keep an eye at measured center, ensure to monitor in real time the reverse osmosis filter of water purification machine.The signal sent pressure detection switch a20, pressure detection switch b21 also beyond the clouds server can carry out analyzing and processing, thus replaces the effect of computer board 22, reduces hardware and uses, reduce production cost.
Above content described in this specification sheets is only made for the present invention illustrating.Those skilled in the art of the present invention can make various amendment or supplement or adopt similar mode to substitute to described specific embodiment; only otherwise depart from the content of specification sheets of the present invention or surmount this scope as defined in the claims, protection scope of the present invention all should be belonged to.
