It is further to carry out gas-liquid mixed.Described return flow line B is furnished with return valve 9, and after self-priming process is completed, return valve 9 will return
Discharge orifice is closed so that the liquid of delivery chamber is not returned in suction room, reduces volumetric loss, improves the efficiency of pump.Described
The closing mode of return valve 9 is automatic, i.e., when pump completion self-priming process enters normal work, the pressure of liquid in delivery chamber
Rise, forms pressure difference between impeller suction chamber, overcomes the spring force of return valve 9 to close return valve automatically.After pump parking, pump
Pressure eliminates between chamber and impeller suction chamber, and the spring compressed on return valve again automatically opens return valve 9.
The present invention operation principle be：
Pump prestart, liquid is poured into the pump housing and is in and beats to groove L (i.e. suction line inlet center line), return valve 9
Open state, delivery chamber communicate with suction room, after impeller rotation, will suck the liquid in room and impeller, extrusion is transported to through impeller
In room, negative pressure is formed at impeller inlet, the pressure in suction line 13 thus is opened inlet valve 1 higher than the pressure of suction room,
Gas in suction line enters impeller through sucking room, the liquid in delivery chamber through return port, suck room, be drawn onto impeller again and enter
Mouth carries out gas-liquid mixed, and gas-liquid mixture is transported to delivery chamber by impeller, because gas-liquid separation chamber A volume is sufficiently large so that
Flow velocity is reduced, and gas-liquid separation is carried out by the difference of liquids and gases proportion, and gas is discharged through air bleeding valve 8, and liquid is again through backflow
Hole returns to suction room, is mixed with gas in impeller eye, circulated according to this, until the gas in suction line 13 is by emptying
Only, because differential pressure action, return valve 9 are closed, now pump just completes self-priming and reaches normal work.
Embodiments of the present invention are the foregoing is only, are not intended to limit the scope of the present invention.It is all in the present invention
Spirit and principle within made any modification, equivalent substitution and improvements, extension etc., be all contained in protection scope of the present invention
It is interior.
