Single-stage centrifugal pump structure and parts introduction
We understand the pump structure, you can intuitively know what this pump looks like, which parts make up, which deepens the memory for the type of pump we know. Next, Xiaobian bring you a single-stage centrifugal pump structure and parts introduction, I hope everyone knows more single-stage centrifugal pump has more help. First of all, let's look at the single-stage centrifugal pump structure diagram. Single-stage centrifugal pump structure and parts introduction Single-stage centrifugal pump is mainly composed of the following components: 1, pump casing pump axial split and radial split two. Most single-stage centrifugal pump housing is volute, multi-stage pump radial split shell is generally a circular shell or a circular shell. 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 part of the work, the pump through the impeller on 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 internal and external pump leakage. The seal ring, made of wear-resistant material, fits over the impeller front and rear covers and pump housing and can be replaced after wear. 4, shaft and bearing pump shaft fixed impeller, one end mounted coupling. According to the size of the pump, the bearings can use rolling bearings and plain bearings. 5, shaft seal There are two general mechanical seal and packing seal. General pumps are designed to both packing seal, but also can be installed mechanical seal. About single-stage centrifugal pump structure and parts introduction, Xiaobian said this, we can control the structure to recognize parts and understand their purpose.
