mine drainage pumps have the characteristics of high efficiency, high power, multiple voltage options, compact structure, stable operation, convenient installation and intelligent control, which provide strong guarantees for the safe production and drainage work of mines.

Diesel engine fire pump units have become an indispensable and important equipment in fire protection systems with their strong power, wide range of flow and head, stable and reliable performance, highly automated control system, efficient and energy-saving operation characteristics, convenient and fast installation and maintenance methods, wide adaptability and high cost performance.

Fire pump is a kind of equipment specially used to carry water source and transport fire-extinguishing water. It is widely used in various buildings, factories, docks, mines, ships and other places. It plays a vital role in controlling and extinguishing fires.

The factors affecting centrifugal pump cavitation are issues that must be considered in the design and use of centrifugal pumps. However, due to different research focuses, and most of them are research on a certain parameter that affects centrifugal pump cavitation, the research results are relatively scattered. , and some of the views are contradictory. This article analyzes the impact of material characteristics of flow-passing parts on cavitation in centrifugal pumps.
