Single-stage centrifugal pump structure: 1, the main components of single-stage centrifugal pump: pump shell pump axial split and radial agent two. Most single-stage centrifugal pump shell are volute, multi-stage centrifugal pump radial split shell is generally a circular shell or a circular shell. The general volute pump housing cavity was spiral-type runner. Used to collect the liquid from the impeller, and guide the diffuser to the pump outlet. Pump housing to withstand all the pressure of work and liquid heat load. 2, single-stage centrifugal pump main components: impeller impeller is the only part of the work, 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, single-stage centrifugal pump main components: Seal ring seal ring is to prevent internal and external leakage pump leakage, made of wear-resistant seal ring material, set in the impeller front and rear cover and the pump casing. Can be replaced after wear. 4, single-stage centrifugal pump main components: one end of the shaft and bearing pump impeller fixed shaft mounted coupling. According to the size of the pump, the bearing cho chooses the rolling bearing and the sliding bearing. 5, single-stage centrifugal pump main components: Shaft seal There are two general mechanical seal and packing seal. Pumps are generally set into both juice filling seal, but also can be installed mechanical seal. Single-stage centrifugal pump features: 1, energy-efficient: CFD CFD, analyze and calculate the pump pressure distribution and velocity distribution, optimize the pump flow channel design, to ensure that the pump has an efficient hydraulic shape line, improve the pump s efficiency. 2, easy installation and maintenance: vertical pipe structure, the import and export of the pump can be installed in the pipeline as any position and any direction, installation and maintenance is very convenient. 3, smooth operation, safe and reliable: Motor shaft and pump shaft for the coaxial straight, high concentricity, stable operation, safe and reliable. 4, stainless steel sleeve: shaft sealing position is relatively easy to rust, direct-coupled pump shaft once corroded, easy to cause mechanical seal failure. STG pump fitted here with stainless steel bushings to prevent corrosion occurred, improve the shaft life, reduce operating and maintenance costs. 5, Bearing: The pump is equipped with motor, Y [Y2] 280 below the shaft end bearings [including Y180 the following fan-side bearing] with closed bearings, normal use, maintenance-free motor bearings. 6, mechanical seal: mechanical seal base member is generally used rubber bellows structure, the traditional mechanical seal shaft seal by the O-ring seal into two parts of the rubber seal, sealing water in the media to improve the sealing effect.
