Description
Technical field
The invention belongs to water pump technologies, are related to a kind of intelligent centrifugal pump.
Background technology
When Ordinary Centrifugal Pumps work in the environment for having suction head, need to form vacuum in suction line, method has
It is several below：
1, vacuum pump is installed, emptied the air in inlet pipeline with vacuum pump.The disadvantage is that investment is big, occupation of land face adds
Greatly, it is not easy to which realization automatically controls；
2, negative-pressure vacuum drainage tank is installed, using the volume of vacuum diversion volume, the air in inlet pipeline is emptied.It is lacked
Point is that investment is big, takes up an area face and increases.
Therefore, existing centrifugal pump in the environment with certain altitude difference in use, in order to by pipeline air empty,
Floor space is larger, and use cost is also larger.
Invention content
The present invention existing above problem in view of the prior art, provides a kind of intelligent centrifugal pump, the present invention to be solved
The technical issues of be：The floor space for how reducing this centrifugal pump reduces the use cost of this centrifugal pump.
The object of the invention can be realized by following technical proposal：
A kind of intelligence centrifugal pump, the centrifugal pump includes the pump housing, and motor and pump chamber, the motor are provided in the pump housing

Working principle of the present invention is as follows：This centrifugal pump when in use, can first pass through water injection pipe water filling in the pump housing, until
It is filled with water in reflux road, pump chamber etc. so that gas-liquid can be mixed preferably, and the return valve covered that flows back at this time, which is in, to be beaten
The state opened；Then start water pump, motor meeting impeller component high-speed rotation so that gas-liquid separation, lighter gas pass through
Outlet pipe is discharged, and heavier water then the gravity the effects that under be back in pump chamber, and be back to close to water inlet by the road that flows back
At pipe, mixed once is carried out again with the air in pipeline, and gas-liquid separation, exhaust are then carried out by impeller assembly again, it is so anti-
Multiple cycle, until the air in pipeline is drained.Impeller assembly is rotated further, and the pressure in pump chamber gradually increases, until will return
Stream valve pushes up back inside, sealing reflux road, and the water in pump chamber is then no longer back at water inlet pipe at this time, and the water in pipeline can be through water inlet
It is outer that pipe, impeller assembly, pump chamber and outlet pipe drain into pump.
