0.5 mm 23.0 %。
The method of above-mentioned excessively husky experiment, 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 invention are as follows：
Experimental rig through the invention and test method can effectively examine and determine the service life of water meter turbine, examine and determine impeller axle
Wear-resistant degree, it is ensured that produce the water meter of high resistance against wear degree.
Description of the drawings
The present invention will be further described below with reference to the drawings.
Fig. 1 is the main structure diagram of the present invention；
Fig. 2 is the overlooking structure diagram of the present invention；
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 implementation mode
Attached drawing is specific embodiments of the present invention.As shown in Figures 1 to 3, the excessively husky experimental rig of this kind of water meter, including a water
The water pipe circuit 1 of placing flat, water pipe circuit 1 by be sequentially connected in series the first visor 2, flowmeter 3, cooling pipeline section 4, the second visor 5,
Water pump 6 forms, 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 controller 8
With power supply 9, run time, the operation frequency of water pump 6 are controlled by frequency converter 7 and time controller 8；Cool down pipeline section 4 with
The influent hopper 10 of upper and lower directions is installed, that is to say, that influent hopper 10 is perpendicular to water pipe circuit 1, water inlet between the second visor 5
Manually-operated gate 11 there are one being set on funnel 10.First visor 2 and the second visor 5 are one section of transparent pipe respectively, such as glass tube, thoroughly
Bright conveying pipeline etc. is used 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 goes out temperature drop pipe 43.
The method for crossing husky experiment：The mixed sand used in this method is by three kinds of variable grain degree（Granularity is indicated with g）'s
Sand forms, respectively：0.09mm < g1≤ 0.125 mm；0.125mm <G2≤0.25mm and 0.25mm<G3≤0.5mm,
The mass percent of three kinds of sands is respectively： g1：29.0 %；g2：48.0 %；g3：The ratio of 23.0 %, water and mixed sand is：
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 run time and
The frequency is run, water pump is then started, so that the husky water in water pipe circuit is formed cycle, while temperature lowering water is passed through 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.
