With the development of the national economy, the demand for sewerage pumps in various departments gradually increases. It is often necessary to transport some mediums with large temperature changes, high solid contents and strong corrosiveness. If the slurry pump with common structure is easily clogged and leaks , It is difficult to ensure long-term effective pump work. According to the situation in the Yunnan-Guizhou mine transport media developed a non-clogging, no leakage of new cyclone non-clogging pump below to 50XW-32-type hydrocyclone pump, for example, focuses on the type of pump structural features, working principle . 1. Structural Features The pump is mainly composed of the pump body, impeller, suction section and other components, the end packing seal, the pump shaft with rolling contact ball bearings and angular contact location, through the coupling to pump and motor. Pump inlet and outlet and the axis of the pump are at right angles, the impeller used semi-open structure, placed on the side of the volute chamber, volute flow passage in front of the impeller is very spacious, it can convey a variety of impurities without the fluid Blockage, with good through performance; As the pump inlet front suction chamber, the working medium from the radial through the suction chamber into axial to the pump chamber, and the packing is installed in the right side of the suction chamber, basically Do not bear the pressure, so as to ensure the reliability and life of the seal; when the impeller rotates, the pump produces a strong axial vortex effect, so that the medium in the suction chamber continuous flow into the pump chamber, the seal chamber to withstand the pressure is small, Even if the shutdown, due to packing seal, the pump can ensure no leakage; impeller and the pump without sealing gap, the operation will not be reduced due to wear and tear of the pump efficiency; pump manufacturing simple, low cost, practicality. 2. Working principle Swirling pump is named for its internal vortex motion. The impeller is driven by the shaft to rotate in the back chamber of the pump. The fluid is directly or indirectly acted on the pump chamber by the impeller to make a strong axial vortex motion. Vortex middle pressure is low, so you can continue to suck the liquid. Axial vortex movement of the pressure and circumferential velocity along the radial increase in the periphery to form a certain energy circulation, and finally become through-flow discharge pump chamber.
