Abstract
A water-filling free centrifuging pump operation system comprises a centrifuging pump and a water inlet tube and is characterized in that a water storing tank is arranged between the water inlet tube and a water inlet port of the centrifuging pump. The water level of the water storing tank is higher than the water inlet port of the centrifuging pump, and the water inlet tube is connected with the upper portion of the water storing tank. By arranging the water storing tank in a water inlet pipeline of the centrifuging pump, the problem that the air enters the water pump and the water inlet pipeline because of leakage of a bottom valve during operation is solved, and the water-filling free centrifuging pump operation system is simple in structure and good in effect.
Description
Technical field
The utility model relates to the operational system of exempting to pour water when the bottom valve leakage takes place in a kind of operational system of centrifugal water pump, particularly centrifugal water pump back out of service.
Background technique
Centrifugal water pump is simple in structure with it, use is easy to maintenance, efficient is higher and become the most popular a kind of water pumps in field such as industry, agricultural.It is the high speed rotating that relies on water pump vane that Centrifugal water pump draws water, and in pump case, forms low pressure area, and water is inhaled in the water pipe under the effect of atmospheric pressure.One of key condition of centrifugal water pump proper functioning is that water pump and intake pipe are air tight, simultaneously also suck air not.Therefore unidirectional bottom valve all is equipped with in centrifugal water pump intake pipe lower end, prevents to leak.
Fig. 1 is the schematic representation of existing technology, after centrifugal water pump 1 stops, leaking like bottom valve 5; Current back pool in the water inlet suction pipe 4; Produce negative pressure in centrifugal water pump 1 and the water inlet suction pipe 4, air gets into water pump 1 and water inlet suction pipe 4 through leakage point, causes centrifugal water pump 1 not draw water.In reality is used; Centrifugal water pump because of the bottom valve of water pump because of reasons such as mechanical failure, seal ring damage, mechanical admixture is stuck; Be easy to generate the phenomenon of water pump or inlet pipeline air inlet and cause moving undesired, start the exhausting air of need pouring water, the operation of feed water pump and operation bring very big inconvenience.
The model utility content
The utility model is the shortcoming to above-mentioned existence, and a kind of technological scheme is provided, and a water storage tank is set in the inlet pipeline of centrifugal water pump, and the water intake of centrifugal water pump is in the bottom of water storage tank; Intake pipe is on the top of water storage tank; The device that keeps the water storage tank water level is set, after realization centrifugal water pump bottom valve leaks, does not pour water and to put into operation once more.
The technological scheme that technical problem adopted that the utility model solves is:
A kind of centrifugal water pump operational system of exempting to pour water comprises centrifugal water pump, intake pipe, it is characterized in that between the water intake of intake pipe and centrifugal water pump, being provided with water storage tank, and the water level of water storage tank is higher than the water intake of centrifugal water pump, and intake pipe is connected with water storage tank top.
During practical implementation, the water intake of centrifugal water pump is connected on the water tower, and is provided with safety check; The intake pipe lower end is provided with bottom valve.
Said structure on one type of prior art syringe, is provided with water storage tank between the water intake of intake pipe and centrifugal water pump; The water level of water storage tank is higher than the water intake of water pump, like this, even leaking appears in the bottom valve of water pump; Current in the intake pipe lose into air, but the raw water service pump normal starting still of the water in the water storage tank, and the air in the intake pipe of starting back is because atmospheric effect is stored in the top of water storage tank; And do not get into water pump, can not influence the operation of water pump.
The beneficial effect of the utility model is: the utility model is through being provided with water storage tank in the inlet pipeline of centrifugal water pump, solved centrifugal water pump bottom valve in service and leaked and cause water pump and intake pipe to advance the problem of air, and is simple in structure, effective.
Description of drawings
Below in conjunction with accompanying drawing and embodiment model utility is further specified.
Fig. 1 prior art constructions schematic representation.
Fig. 2 the utility model embodiment's structural representation.
Among the figure: 1, centrifugal water pump 2, water storage tank 3, safety check 4, intake pipe 5, bottom valve
Among Fig. 2; A kind of centrifugal water pump operational system of exempting to pour water comprises centrifugal water pump 1, intake pipe 4, is provided with water storage tank 2 between the water intake of intake pipe 4 and centrifugal water pump 1; The water level of water storage tank 2 is higher than the water intake of centrifugal water pump 1, and intake pipe 4 is connected with water storage tank 2 tops.The water intake of centrifugal water pump 1 is connected on the water tower 6, and is provided with safety check 3; Intake pipe 4 lower ends are provided with bottom valve 5.
After centrifugal water pump 1 quits work, after bottom valve 5 leakages, the current back pool in the intake pipe 4, air gets into intake pipe 4, and the water intake of centrifugal water pump 1 is located at water storage tank 2 bottoms, air can not get in the centrifugal water pump 1.When centrifugal water pump 1 starts once more; Water in the water storage tank 2 is started working centrifugal water pump 1; And the air in the intake pipe 4 because the water level of water storage tank 2 remains on the into position above the water centrifugal water pump 4, has guaranteed the normal operation of centrifugal water pump 2 because atmospheric effect gets into water storage tank 2 tops.
