West Baoquan Water Treatment Equipment Co. (www.xianbaoquan.com) is located in Xi'an, Shaanxi Chang'an Building 15, Room 1-2408 Xi'an Changfeng Park Road, Contact: Mr. Wang sewage pump is a pump and motor Siamese, and at the same time Under sneak liquid pumps work, compared with the general horizontal or vertical sewage pump pumps, sewage pumps obviously has the advantage of the following aspects: a compact, small footprint. Due to sneak under the liquid sewage pump work, it can be installed directly in sewage tanks, pumping stations without having to build a dedicated machine used to install pumps and can save a lot of land and infrastructure costs. 2 easy installation and maintenance. Small sewage pump can be freely installed, a large sewage pumps are generally equipped with automatic coupling device can be automatically installed, installation and maintenance very easy. Centrifugal pumps driven by electric motors in general, before starting the pump, the pump and the suction pipe filled with liquid. When the impeller rotates at high speed, the impeller vanes to drive a rotation of the liquid line, single-stage pump, the centrifugal force, the liquid left behind the outer edge of the impeller (the flow rate can be increased to 15 ~ 25m / s) from the center of the impeller pump fire tangent, kinetic energy also increases. When the liquid enters the pump housing, since the volute casing of the pump flow path is gradually expanded, the flow rate of the liquid pump is decreased, a portion of the kinetic energy into static pressure multistage pump can pipeline, so a high pressure liquid flowing along the discharge outlet. At the same time, the center of the impeller due to the liquid being thrown out and create a vacuum, while at the level of the pressure Pa is higher than that at the center of the impeller, so that the liquid in the suction pipe into the pump differential pressure. Constantly rotating impeller, the liquid is also continuous inhalation and pressed out. Because of centrifugal pumps have been able to transport liquids, mainly by the centrifugal force, it is called centrifugal pump.
