A certain amount of sand, the time, which has been grown, to generate abrasion to also wheel shaft, the rotation of impeller is influenced, to influence the precision of water meter.?
In current water meter exfactory inspection, not to the measurement request of the abrasion containing sand in water, thus just there is no husky experimental rig yet.
Summary of the invention
In order to make up for the defects of the prior art, the utility model provides a kind of excessively husky experimental rigs of water meter.
The utility model is achieved by the following technical solution:
A kind of excessively husky experimental rig of water meter, characterized in that including horizontal positioned water pipe circuit, in the water pipe circuit according to
The first visor of secondary series connection, flowmeter, cooling pipeline section, the second visor, water pump, checklist are connected between the first visor and water pump,
The water pump is sequentially connected in series frequency converter, time controller and power supply;Installation water inlet leakage between the cooling pipeline section and the second visor
Bucket, the influent hopper are equipped with a manually-operated gate.
The influent hopper is vertical with water pipe circuit.
Exhaust pipe is equipped between first visor and flowmeter, the exhaust pipe is equipped with manual switch.
The method for carrying out husky test using the excessively husky experimental rig of above-mentioned water meter, characterized in that first connect checklist
Connect between the first visor and water pump, from influent hopper into water pipe circuit topped up with water, mixed sand is then added, shuts hand-operated valve
Door observes in water pipe circuit whether have bubble by the first visor and the second visor, if so, manual switch is then opened, by gas
It bleeds off, then shuts manual switch again, start water pump, so that the husky water in water pipe circuit is formed circulation, while logical in cooling pipeline section
Enter temperature lowering water, stop water pump after 8 hours, unload checklist and test, sees whether checklist is qualified.
In the method for above-mentioned excessively husky test, the granularity of the mixed sand are as follows: the mm of 0.09 mm < g≤0.5.
The method of above-mentioned excessively husky test, mixed sand are made of the sand of three kinds of variable grain degree, mass percent are as follows:
0.09 mm < g≤0.125 mm, 29.0 %;0.125 mm < g≤ 0.25 mm 48.0 %;0.25 mm < g ≤
0.5 mm 23.0 %。
The method of above-mentioned excessively husky test, characterized in that 0.6 gram is added in every 2 liters of water by the mixed of three kinds of variable grain degree
It closes husky.
The beneficial effects of the utility model are:
By the experimental rig and test method of the utility model, the service life of water meter turbine can be effectively examined and determine, is examined
Determine the wear-resistant degree of impeller shaft, it is ensured that produce the water meter of high resistance against wear degree.
Detailed description of the invention
The utility model will be further described below with reference to the accompanying drawings.
Fig. 1 is the schematic view of the front view of the utility model;
Fig. 2 is the overlooking structure diagram of the utility model;
Fig. 3 is the schematic cross-sectional view of cooling pipeline section.
In figure, 1 water pipe circuit, 2 first visors, 3 flowmeters, 4 cooling pipeline sections, 41 hollow structures, 42 into temperature drop pipe,
43 go out temperature drop pipe, 5 second visors, 6 water pumps, 7 frequency converters, 8 time controllers, 9 power supplys, 10 influent hoppers, 11 manually-operated gates,
12 exhaust pipes, 13 manual switches, 14 checklists.
Specific embodiment
Attached drawing is specific embodiment of the utility model.As shown in Figures 1 to 3, the excessively husky experimental rig of this kind of water meter, including one
A horizontal positioned water pipe circuit 1, water pipe circuit 1 are regarded by the first visor 2, flowmeter 3, cooling pipeline section 4, second being sequentially connected in series
Mirror 5, water pump 6 form, and checklist 14 is connected between the first visor 2 and water pump 6, and water pump 2 is sequentially connected in series frequency converter 7, time control
Device 8 and power supply 9 processed control runing time, the operation frequency of water pump 6 by frequency converter 7 and time controller 8;Cooling pipe
Section 4 and second up and down direction is installed between visor 5 influent hopper 10, that is to say, that influent hopper 10 perpendicular to water pipe circuit 1,
Influent hopper 10 is equipped with a manually-operated gate 11.First visor 2 and the second visor 5 are one section of transparent pipe, such as glass respectively
Pipe, transparent conveying pipeline etc. are to observe bubble.
There is gas in water pipe circuit 1 in order to prevent, exhaust pipe 12 is installed between the first visor 2 and flowmeter 3, is vented
Pipe 12 is also vertical with water pipe circuit 1, and manual switch 13 is installed on exhaust pipe 12.
There are many method that pipeline section 4 cools down that cools down, and in the present embodiment, the outer wall of cooling pipeline section 4 is hollow structure 41, hollow
It is arranged in structure 41 into temperature drop pipe 42 and temperature drop pipe 43 out.
The method for crossing husky test: mixed sand used in this method is by three kinds of variable grain degree (granularity is indicated with g)
Sand composition, is respectively as follows: the mm of 0.09mm < g1≤0.125;0.125mm < g2≤0.25mm and 0.25mm < g3≤0.5mm,
The mass percent of three kinds of sands is respectively as follows: g1:29.0 %;G2:48.0 %;The ratio of g3:23.0 %, water and mixed sand are as follows:
0.6 gram of mixed sand is added in 2 liters of water.Checklist is connected between the first visor and water pump first, from influent hopper to water pipe
Then topped up with water in circuit is added mixed sand according to aforementioned proportion, shuts manually-operated gate, seen by the first visor and the second visor
Whether have bubble, if so, then opening manual switch, gas is bled off if examining in water pipe circuit, then shuts manual switch again, at this moment
Water pipe circuit just becomes a totally-enclosed circuit, and water is filled in it, without bubble;Set water pump runing time and
The frequency is run, water pump is then started, so that the husky water in water pipe circuit is formed circulation, while being passed through temperature lowering water in cooling pipeline section, reaches
Stop water pump after to setting time, setting time is generally 8 hours, unloads checklist and test, and sees whether checklist is qualified.
