Inventory models of vertical slurry pump performance parameters, vertical slurry pump works

In the coal preparation plant production practice, the vertical slurry pump is not only widely used in slime water, circulating water, coal slurry and heavy medium suspension fluid transport operations, but also as a hierarchical enrichment) cyclone, heavy Medium (water) sorting cyclone, filter press feed pump use, but also directly affect the process indicators. Therefore, as an important auxiliary equipment for a coal preparation plant, the performance of the coal preparation plant directly affects the normal operation of the production system. Inventory of vertical slurry pump model performance parameters, the vertical slurry pump works (A) Vertical slurry pump works Slurry pump centrifugal pump. Slurry pump works as shown in Figure 1-1. The outer shell of the slurry pump container is stationary, and the impeller in the housing is driven by the motor to rotate at a high speed. The centrifugal force generated by the rotation of the impeller acts on the liquid and thrushes the liquid filled in the channel between the impellers from the center of the impeller to the periphery Thrown into the pump shell, so that the liquid kinetic energy and pressure can be obtained; due to the outer impeller pump casing section is constantly increasing, so the kinetic energy of the liquid is partially converted to pressure energy, so the pump outlet liquid with greater pressure, You can drain the liquid to a certain height and distance. In addition, while the liquid is thrown to the periphery from the center of the impeller, a low-pressure belt (having a certain degree of vacuum) is formed at the inlet of the impeller. The liquid in the liquid pool passes through the filter through the filter and enters the impeller through the filter to supplement The amount of liquid flowing out of the impeller. Impeller constantly rotating, so that the liquid to obtain centrifugal force, the liquid is continuously inhaled and pressed out, so that the centrifugal pump on an endless stream of water. (B) the vertical slurry pump model performance parameters SP liquid slurry pump models are: 40PV-SP (R), 65QV-SP (R), 100RV-SP (R), 150SV-SP (R), 200SV 65SV-SP (R) for example, 65 for pump outlet diameter 65mm, QV bracket type, SP series code, R means Rubber lining. ZJL vertical slurry pump models are: 40ZJL-21,40 ZJL-25,40 ZJL-35,50 ZJL-20,50 ZJL-35,50 ZJL-40,65 ZJL-30,80 ZJL-36,100 ZJL-34,150 ZJL-35 Model Meaning : Take 65ZJL-30 for example, 65 means pump outlet diameter 65mm, ZJ means slurry pump, L means vertical, 30 means impeller diameter 30cm. Liquid slurry pump is mainly used in coal washing, dressing is an important component of wear-resistant slurry pump. (Editor: Huang Nengwen QQ :)
