Description
Technical field
This utility model is related to self-priming pump technical field, more particularly, to a kind of leak free magnetically-actuated self priming pump.
Background technology
The operation principle of self priming pump is：First water is filled in pump case before starting mode of pump（Or itself have water in pump case）.Open
After dynamic, impeller high-speed rotation makes the current direction volute in impeller conduit, and at this moment entrance forms vacuum, makes to open into water non-return flap, inhales
The air entering in pipe enters in pump, and reaches outer rim through impeller conduit.Self priming pump belongs to self priming centrifugal pump, and it is tight that it has structure
Gather, easy to operate, operate steadily, safeguard easily, efficiency high, life-span length, and have the advantages that stronger suction capacity.Pipeline is not required to
Bottom valve is installed, before work, only need to ensure that containing quantitation in the pump housing draws liquid.Different liquids can adopt unlike material self priming pump.From
The suction lift of sucking pump, relevant with the factor such as seal clearance, the revolution of pump, separation chamber's liquid level before impeller.Seal before impeller
Gap is less, and suction lift is bigger, is typically taken as 0.3 ~ 0.5 millimeter；When gap increases, in addition to suction lift declines, pump
Lift, efficiency all reduce.The suction lift of pump increases with the increase of peripheral speed u2 of impeller, but to maximum suction lift
When, revolution increases and suction lift just no longer increased, and now simply shortens self-priming time；When revolution declines, suction lift
Then with decline.In the case that other conditions are constant, suction lift increases also as the increase of water storage height（But nor
Exceed the optimal water storage height of separation chamber）.In order to preferably make mixing wastewater with air in self priming pump, the blade of impeller must be less, makes
The pitch of leaf grating increases；And preferably adopt half-opened impeller（Or the impeller that impeller conduit is wider）, so more convenient for backwater deeply
Inject in impeller leaf grating.
Self priming pump is used mostly in the transmission of various liquid, may contain corrosive substance in liquid, and silt etc.
Debris, the most sealing effectiveness of existing self priming pump is inconspicuous on the market, in transmitting procedure, can reveal partially liq and enter the pump housing
In internal structure, damage its internal parts, the using effect of the impact pump housing, shortened the service life of self priming pump, for this
We design a kind of leak free magnetically-actuated self priming pump, to solve the above problems.
