The use of centrifugal pumps in the coal mining industry

Centrifugal pumps play a crucial role in coal mining industry production. It can not only transport water to the comprehensive mining team, machine excavation team, preparation area, dust prevention area, ventilation area and other working units underground in coal mines, but also timely discharge wastewater outside the well when a water leakage accident occurs underground. There are many types of centrifugal pumps, which can be divided into single-stage centrifugal pumps and multi-stage centrifugal pumps according to the number of working impellers; According to working pressure, it can be divided into low-pressure centrifugal pumps, medium pressure centrifugal pumps, and high-pressure centrifugal pumps; According to the impeller inlet method, it can be divided into single-sided inlet centrifugal pumps and double-sided inlet centrifugal pumps; According to the joint form of the pump casing, it can be divided into horizontal open centrifugal pumps and vertical joint surface centrifugal pumps; According to the position of the pump shaft, it can be divided into horizontal centrifugal pumps and vertical centrifugal pumps; According to the way the water from the impeller is directed to the extrusion chamber, it can be divided into volute centrifugal pumps and guide vane centrifugal pumps.
