China's pump is mainly to achieve the transport of liquid substances such as water, oil, emulsion, acid and alkali liquid, liquid metal, suspenders, etc., but as the demand for the pump to the industry continues to grow, the pump From traditional to modern. Meet the needs of more and more markets. Among them, the transport of abrasive or corrosive slurry materials, impurity pump has a very important position. So how does the impurity pump work? Impurity pump working principle Impurity pump mainly by the pump, impeller, pump cover, shaft, front guard, rear guard, bushings, fixed cutter, moving knife and suspension, bearing components and other components. Pump is designed to open the door before and after the open, the advantage of overhauling, do not disassemble the pump, piping, exit the rotor components, repair or replacement, set cutterhead. Suspension bearing components support the pump rotor components, in order to balance the axial force pump, the impeller cover is provided with pay leaves. Rolling bearings bear radial and residual axial force of the pump. Impurities pump mechanical seal. In the shaft through the mechanical seal parts, equipped with bushings to protect the pump shaft to prevent wear. Between the sleeve and the shaft with "O" ring. To prevent air intake and leakage. Pump cover flow components, the series of impurity pump for the single-stage, single-suction centrifugal impurities pump. PNL type which is vertical structure. Over-current parts made of wear-resistant alloy materials, PNJ type of rubber material, long life. The gap between the impeller and the jacket and impeller and guard can be adjusted to maintain high efficiency. With the development of economy and science and technology, there are many special materials that need to be dealt with in many fields, such as garbage, sewage, grit, bones, animal fur, solid materials and so on. At this moment, special tools are needed to deal with them. At this moment, the impurity pump acts as a scavenger.
