4 the structure of vane pump

an overview of the structure of 4 vane pump vane water pump can be classified according to the following characteristics. 1. According to the main shaft direction 0 horizontal: main shaft in horizontal. Vertical: spindle vertically. Inclined type: axis tilted. 1 according to the centrifugal impeller type 0: centrifugal impeller. Francis: mixed flow impeller. Axial flow: the axial flow impeller. Work according to the suction mode 0 single-suction: single suction impeller. 2 double suction: double suction impeller. 4, according to the series single stage 0: an impeller. Stage: the same shaft with two or more than two of the impeller. 5 ^ adjustable blade in proportion of blade installation method: impeller blade Angle can be regulated through the agency was laid. : fixed blade impeller blade settling Angle is fixed. 6, press 売 body subdivision method 0 sectional: shell in a plane perpendicular to the main shaft subdivision. 2 > sectional: in sectional structure, each level shell are split. 3 > open: the plane part of the shell through the shaft centerline. 4 > levels in the open: in the open structure, subdivision surface water is flat. 5 ^ open in vertical, in the open, the subdivision surface is 91 逬 and level. 6 > inclined in the open: in the open, the subdivision surface is tilted. 1 0 the form of the pump volute, impeller discharge side has a belt of volute chamber shell. 2 > double volute impeller discharge side shell with double volute chamber. 3 > type: inner pressure shell with a circular Jane in vitro. 4 > double shell type: type refers to the outside of the double water pump shell. 8 ^ 0 hanging posture: according to the pump body bearing way under pump body pump, on the base, shaft bearing body hanging in the end. 2 > bracket type: the bottom of the bearing body is fixed on the base, pump body is bearing body in order to hang at one end. 3 > center bearing type: pump body through axis on both sides on the base on the horizontal plane. 9 0 ^ special structure of the vane pump submersible pumps, pump motor and pump driven coaxial straight even one used in water pump, mechanical and electrical integration, simple structure, easy to use. 2 ^ tubular pump: the pump body is equipped with electric motor drive, etc. 3 > shielding pump: pump and motor directly connected ( I share a shaft motor stator inner is equipped with shielding cover, to prevent the liquid into the stator. 4 ^ magnetic pump, motor drive the outer magnetic steel, through magnetic induction and chestnut impeller should be brought together in magnetic rotation, between the inner and outer magnetic steel spacer, completely eradicate liquid leakage. 5 ^ self-priming pump: pump start without irrigation pump again. 6 > pipeline pump: pump as part of the pipeline, without special change pipeline installation.

non-clog pump: pump pumping liquid contained in the solid material will not cause blockage in the pump. The structure of the impeller are single-pass flow, shuangliu, vortex flow and business screw centrifugal.
