Description
Technical field
The utility model belongs to liquid pump apparatus manufacturing technology field, and in particular to a kind of centrifugal pump body.
Background technique
Centrifugal pump is to be rotated using impeller and make water that centrifugal movement occur come work, and water pump is before activation, it is necessary to make to pump
It is full of water in shell and suction hose, then starts motor, pump shaft impeller and water is made to do high speed rotary motion, centrifugation fortune occurs for water
It is dynamic, it is thrown toward impeller outer edge, the runner through volute pump case flows into the pressure pipe road of water pump.The essential structure of centrifugal pump is by six
It is grouped as, is impeller, the pump housing, pump shaft, bearing, sealing ring and stuffing-box, the stabilization that pump housing shape passes in and out water flow respectively
Property serves vital, and the existing pump housing often has the problems such as flow stability is low, at high cost.
Summary of the invention
The utility model aims to solve the problem that the above problem, provides a kind of centrifugal pump body, by the improvement of structure, improves
The stability of water flow, while having saved cost.
According to the technical solution of the utility model, the centrifugal pump body, including the pump housing, the pump housing is interior to be equipped with volute runner,
The input end of volute runner is equipped with water-in flange, and the outlet end of volute runner is equipped with water-output flange, the water-in flange and water outlet
The side of flange is equipped with air vent；Water-in flange be in from outside to inside it is contraction-like, water fender is equipped in water-in flange, water fender
Height is not higher than the center line of water-in flange；The bottom of the pump housing is equipped with the drainage hole communicated with volute runner.
Further, the bottom of the volute runner is equipped with collecting tank, and drainage hole is communicated with collecting tank.
Further, stiffener plate is equipped between the flange face and the pump housing of the water-in flange.
Further, the side of the water-in flange is equipped with an air vent, and the side of water-output flange is equipped with symmetrical two
A air vent.
Further, the junction of the water fender and the neck inner wall of water-in flange is equipped with arc-shaped transition.
The utility model has the beneficial effects that: water-in flange be in from outside to inside it is contraction-like, water blocking is equipped in water-in flange
Plate, the height of water fender are not higher than the center line of water-in flange, improve the stability of water flow, while having saved cost；Reinforce
Gusset and arc-shaped transition etc. ensure that the intensity of structure；The setting of collecting tank ensure that the even running of centrifugal pump.
