Description
Technical field
The present invention relates to centrifugal pump field, specifically a kind of inert vacuum assists self priming pump.
Background technique
Centrifugal pump is that liquid is transported to the most common pump of another place from a place, for irrigating, domestic water
System, sewage treatment and many other applications.Liquid is located at the intracorporal impeller propelled of pump and passes through the pump housing by exporting from priming reservoir
Pipe discharge.Spiral case inlet opening and impeller are concentric.The rotation of impeller is got rid of liquid outward to impeller outer edge and is concentrated from pump housing outlet
Discharge.When liquid drives outward, vacuum is generated at center, to suck more liquid into pump.
The major limitation that centrifugal pump uses first is that, when pump in be full of air when impeller air can only be driven to rotate, because of sky
The centrifugal force that the very light in weight of gas unit volume generates is very small, and usually the air in pump chamber and inlet tube cannot be discharged, they do not have
There is the ability that voluntarily sucking liquid works.In general pump field, general non-diving installing type centrifugal pump is in addition to itself
Outside the self priming pump of included self-suction function and the centrifugal pump by positive pressure water inlet, the centrifugal pump of most of dry type installations is required to pumping
Import pipe end configures bottom valve, needs to pour water to pump and can start before first time starts.For example draining etc. uses
Environment, the operation of pump be it is discontinuous, need repeat constantly artificially pour water into pump.The bottom although pump machine is mounted with bottom valve
Valve has natural defect, is mainly manifested in: 1. bottom valves are heavy, and are mounted on and are not easy to sling, monitor, maintain and tie up under liquid
It repairs；2. bottom valve being since long period of soaking be easy to cause burn into a liquid and then influences sealing effect, it is serious can be in secondary water suction
Shi Wufa work；3. generated solid particle can enter in circulating liquid in production and process, solid particle is in bottom valve
Aggregation and adherency can make bottom valve that can not be fully sealed, and bottom valve can fail at once；4. since bottom valve is mounted on into water pipe end, bottom
The water entering surface that valve itself will affect pump manufactures into insufficient water.Secondly, in field work, or when needing unattended, need
The water source to be drained may be drained at any time, but due to unattended, or cannot be found in time, water pump for a long time at
When dry turn, it is easy to burn mechanical seal, even result in entire machine and be damaged.
In view of said circumstances, need to design a kind of vacuum aided self priming pump, to realize following target:
1. not needing installation bottom valve
2. centrifugal pump can voluntarily rapid vacuumizing
3. can directly carry out anhydrous starting without pouring water into pump before starting for the first time；
4. can realize self-priming and can repeatedly, lasting self-priming；
5. during self-priming, or when pump is in anhydrous operating for a long time, pump will not be damaged；
6. when centrifugal pump is started to work, vacuum pump can stop working when vacuumizing end, it is in sleep state, so as to substantially
The service life that degree ground saves the energy, reduces mechanicalness noise, improves vacuum pump,
The object of the present invention is to provide a kind of inert vacuums to assist self priming pump for summary of the invention, to solve to be centrifuged under the conditions of the prior art
