centrifugal pump lead is according to the design of principle, high-speed centrifugal impeller blades rotating water rotation, driven water throw, achieve the purpose of transmission. centrifugal pump have a variety of, from the use can be divided into civil and industrial use pump; from transport medium can be divided into clear water pump, impurity pump, anti-corrosive pumps, etc.

centrifugal pump working principle is: centrifugal pump is able to put the water away is because only centrificating. pumps, pump body before work must be cans full feed water and creates a vacuum, when the impeller fast turns, leaf prompted water rapidly rotating, rotating centrifugal water from under the action of the impeller and fly in the water pump were thrown from within, after the central part of the impeller formed vacuum area. water water in the atmospheric pressure (or water pressure) under the action of water pipe pressure came through a tube. this cycle unceasingly, can achieve continuous pumped. in the centrifugal pump is worth mentioning: before initiating must to the pump housing filled with water, can start, otherwise after pump body will be unable to complete the pump body absorb fluid, causing fever, vibration, not water, generate "idling," on the pump damage (hereinafter referred to as "gas tied") cause e accidents.

centrifugal pump is a lot of more phyletic, classification methods common have the following kinds way 1 press impeller inhaled way points: single suction style centrifugal pump double suction type centrifugal pump. press the impeller number points: single grade centrifugal pump mulfistage centrifugal pump. 3 according to the structure of impeller points: open impeller centrifugal pump impeller half open centrifugal pump closed impeller centrifugal pump. 4 according to work pressure points: low voltage centrifugal pump medium centrifugal pump high-pressure centrifugal pump edge vertical centrifugal pump. installed in the pump impeller, and tighten within shell 2 in pump shaft 3, driven by motor pump shaft directly. pump shell central has a liquid inhaled 4 and the suction pipe 5 connection. by bottom valve 6 and liquid within the suction pipe into the pump. the liquid on the pump housing and discharge pipe line export 8 9 connection. before starting the in centrifugal pump, the pump housing fill be transported liquid; when activated, driven by the axis high-speed rotating impeller, between the blades with the liquid must also be turning. in the centrifugal force, under the action of fluid from the impeller centers are thrown to obtain energy, rim and high-speed leave volute pump impeller into outer shell. spiral, liquids in gradually expands and slow flow, and for static pressure can change partial kinetic energy, finally with higher pressure inflow discharge pipe, send to need places. the liquid flow by impeller center in impeller center outer formed some vacuum, because the holding tank liquid surface at the entrance of the pressure is greater than pump above the pressure, the liquid will be continuous pressure into the impeller. visible, if impeller constantly rotating, liquid will consistently inhaling and exhaling.
