Description
Technical field
The utility model is related to pump technology field, and in particular to a kind of new self priming pump water inlet.
Background technology
The structure type of self priming pump is a lot, wherein pump for liquid salts, vavuum pump, submerged pump, measuring pump, gear pump, noncorrosive pump,
Acid-proof pump, fire pump flow to direction of rotation.Then the water for coming with right backwater hole stream converges, along spiral case flowing.Due to liquid
Leaf grating is constantly impacted in spiral case, is constantly smashed by impeller, just mixed with air strong agitation, generate air-water mixture, not
Flow disconnectedly and cause the air water can not to separate.Mixture is peeled off in volute outlet by cut water, and separation chamber is entered along short tube.In separation chamber
Interior air is separated, and is drained by outlet, and water still flows to impeller outer edge through left and right backwater hole, and with suction line air phase
Mixing.Such iterative cycles, gradually drain the air in suction line, water is entered in pump, complete self-priming process.Blowdown
Pump, self priming pump, oil pump, membrane pump, screw pump, gear oil pump are identical, and its difference is that backwater does not flow to impeller outer edge, and is flowed to
Impeller eye.Internal-mixing self priming pump on startup, must open the return valve of impeller front lower place, liquid in pump is flow back into impeller and enter
Mouthful.The air that water comes in the presence of impeller high-speed rotation with suction line is mixed, and is formed air-water mixture and is drained into separation chamber.
Here air is discharged and water returns to impeller eye from return valve.So it is repeated, until air is drained, sucts in water
Mixing self priming pump, operation principle and exterior mixing self-priming.
The operation principle of self priming pump is：Water is first filled in pump case before starting mode of pump（Or itself have water in pump case）.Open
Impeller rotates at a high speed the current direction volute made in impeller conduit after dynamic, and at this moment entrance forms vacuum, makes to be opened into water non-return flap, inhales
The air entered in pipe enters in pump, and reaches outer rim through impeller conduit.Self priming pump belongs to self priming centrifugal pump, and it has structure tight
Gather, it is easy to operate, operate steadily, safeguard easily, efficiency high, long lifespan, and have the advantages that stronger suction capacity.Pipeline is not required to
Bottom valve is installed, only need to ensure to be contained in the pump housing quantitatively to draw liquid before work.Different liquids can use unlike material self priming pump.
The water inlet of current self priming pump is made of casting, heavier-weight, and inefficiency, it has not been convenient to cleared up, urgently
It is to be modified.
