Description
Technical field
The utility model is related to water pump technology, be specially it is a kind of can automatic water-returning self priming pump.
Background technology
Self priming pump category self priming centrifugal pump, it have it is compact-sized, easy to operate, operate steadily, safeguard easy, efficiency
High, long lifespan, and have the advantages that stronger suction capacity.Pipeline is not required to installation bottom valve, only need to ensure to contain in the pump housing before work
Quantitatively draw liquid.Different liquids can use unlike material self priming pump.
The operation principle of self priming pump is first to fill water (or itself having water in pump case) before starting mode of pump in pump case.Start
Rotation makes current in impeller conduit to volute to impeller at a high speed afterwards, and at this moment entrance forms vacuum, makes to open into water non-return flap, suction
Air in pipe enters in pump, and reaches outer rim through impeller conduit.The structure type of self priming pump is very much, wherein pump for liquid salts, vacuum
Pump, submerged pump, metering pump, gear pump, noncorrosive pump, acid-proof pump, fire pump are flowed to direction of rotation.Then with right backwater hole stream
The water come converges, and is flowed along spiral case.Since liquid constantly impacts leaf grating in spiral case, constantly smashed by impeller, with regard to same air
It is stirred strongly, generates air-water mixture, and constantly flowing causes air water to separate.Mixture volute outlet by every
Tongue is peeled off, and enters separation chamber along short tube.It is separated in separation room air, is exhausted by outlet, and water is still returned through left and right
Water hole flows to impeller outer edge, and is mixed with suction line air.Such iterative cycles, gradually arrange the air in suction line
To the greatest extent, water is entered in pump, complete self-priming process.
