[Asia Fluid Network News] The main components of the pump and ultimately pump casing (also known as pump), impeller, seal ring, pump shaft, shaft seal device and several other major parts. Today, Asia Fluid Network Xiaobian focused on introducing the main components of single-stage centrifugal pump. Familiar with single-stage centrifugal pump "internal organs" for safe and efficient use of equipment has a positive meaning. 1 pump casing 2 impeller 3 seal ring 4 impeller nut 5 pump cover 6 seal member 7 intermediate support 8 shaft 9 suspension member 1 pump casing pump The shell has two axial and radial partial type. Most single-stage pump housings are volute-type and multi-stage pump radial section housings are typically toroidal or circular housings. In general, the volute-type pump housing cavity has a helical flow path for collecting the liquid flowing out of the impeller and leading it to the diffuser to the pump outlet. Pump housing to withstand all the pressure of work and liquid heat load. (2) Impeller Impeller is the only working part, the pump through the impeller to the liquid work. Impeller structure type is closed, open, semi-open three. Closed impeller blades, front cover, rear cover composition. Semi-open impeller blades and cover from the composition. Open impeller blades only, no front and rear cover. Closed impeller high efficiency, low efficiency open impeller. (3) seal ring The role of the seal ring is to prevent the centrifugal pump of the internal leakage and external leakage. A wear-resistant material made of seal ring, set in the impeller front and rear cover and pump housing, wear and tear can be replaced. (4) shaft and bearing pump shaft fixed impeller, one end mounted coupling. According to the size of the centrifugal pump, the bearings can be used for rolling bearings and plain bearings. (5) Shaft seal There are two general mechanical seal and packing seal. Centrifugal pumps are generally designed to both fill the seal, there can be installed mechanical seal. Centrifugal pump product range, according to the pump shaft position, impeller structure, etc. can be divided into: horizontal centrifugal pump, vertical centrifugal pump, open impeller centrifugal pump, semi-open impeller centrifugal pump and closed impeller centrifugal pump and so on There are more categories in addition to this. Although a wide range of centrifugal pumps, but its several major components is essential. This article is copyrighted industry interconnect (Xiamen) Co., Ltd.
