Abstract
The utility model discloses a centrifugal pump hydrologic cycle is prevented falling pressure equipment and is put relates to the water circulating system field. Including main centrifugal pump, its characterized in that: main centrifugal pump is still through pipeline connection valves in proper order, supplementary centrifugal pump, water tank. The valve passes through flange joint with the pipeline. The utility model discloses the beneficial effect who reaches does: simple structure, easy maintenance can make the pump case of centrifugal pump and the intraductal water that is full of fast that absorbs water when the pump case is managed to find time with the intraductal water that absorbs water, guarantee that water circulating system normally works.
Description
Technical field
The utility model relates to water circulation system field, is specifically related to the anti-lost pressure device of a kind of centrifugal pump water circulation.
Background technique
In water circulation system, centrifugal pump is conventional dynamical element, and it utilizes vane rotary and makes water generation centrifugal motion carry out work.Before activation, must make to be full of water in pump case and suction sleeve, then starting electrical machinery, make pump shaft impeller and water do high speed rotary motion, water generation centrifugal motion, is thrown toward impeller outer edge to water pump, and the runner through volute pump case flows into the setting-out pipeline of water pump.But suck air sometimes in water cycle process, when air constantly gathers to a certain degree, pipeline inner pressure is crossed conference and is caused centrifugal pump to quit work suddenly, water in pump case and suction sleeve is evacuated, again manually must fill water centrifugal pump could normally work, water injection time is long, if adopt vacuum pump to replace centrifugal pump, investment is large, consumes electric energy many.
Model utility content
Technical problem to be solved in the utility model is to provide the anti-lost pressure device of a kind of centrifugal pump water circulation, can make fast to be full of water fast in the pump case of centrifugal pump and suction sleeve when the water in pump case and suction sleeve is evacuated.
For solving the problems of the technologies described above, technical solution adopted in the utility model is:
The anti-lost pressure device of a kind of centrifugal pump water circulation, comprises main centrifugal pump, it is characterized in that: described main centrifugal pump also connects valve, auxiliary centrifugal pump, water tank successively by pipeline.
Further technological scheme is: described valve and pipeline pass through Flange joint.
The beneficial effect adopting technique scheme to produce is: structure is simple, easy to maintenance, can make fast to be full of water fast in the pump case of centrifugal pump and suction sleeve when the water in pump case and suction sleeve is evacuated, and ensures that water circulation system normally works.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
Fig. 1 is structural representation of the present utility model.
Wherein: 1, main centrifugal pump, 2, valve, 3, auxiliary centrifugal pump, 4, water tank.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technological scheme in the utility model embodiment, obviously, described embodiment is only a part of embodiment of the present utility model, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
Set forth a lot of detail in the following description so that fully understand the utility model, but the utility model can also adopt other to be different from alternate manner described here to implement, those skilled in the art can when doing similar popularization without prejudice to when the utility model intension, and therefore the utility model is by the restriction of following public specific embodiment.
As shown in Figure 1, the anti-lost pressure device of a kind of centrifugal pump water circulation, comprises main centrifugal pump 1, it is characterized in that: described main centrifugal pump 1 also connects valve 2, auxiliary centrifugal pump 3, water tank 4 successively by pipeline.Preferably, described valve 2 passes through Flange joint with pipeline.
In water circulation system working procedure, if suck that air, pipeline inner pressure excessively cause centrifugal pump to quit work suddenly, water in pump case and suction sleeve be when being evacuated, open the motor of valve 2 and auxiliary centrifugal pump 3, water in water tank 4 can flow through auxiliary centrifugal pump 3, valve 2, be full of pump case and the suction sleeve of main centrifugal pump 1 fast, main centrifugal pump 1 can normally work, thus ensures that water circulation system normally works, and structure is simple, easy to maintenance.
Claims (2)
1. the anti-lost pressure device of centrifugal pump water circulation, comprises main centrifugal pump (1), it is characterized in that: described main centrifugal pump (1) also connects valve (2), auxiliary centrifugal pump (3), water tank (4) successively by pipeline.
2. the anti-lost pressure device of a kind of centrifugal pump water circulation according to claim 1, is characterized in that: described valve (2) and pipeline pass through Flange joint.
