矿井主排水泵房担负着排出井下积水的重要任务,是矿井防治水的重要组成部分,是保证矿井安全的关键环节。目前,很多煤矿大多使用单吸、多级、节段式卧式离心泵,主排水泵承担着矿井的排水任务,磨损和锈蚀速度快,需要定期对水泵进行生井检修。本文分析了目前煤矿中常用的单吸、多级、节段式卧式离心主排水泵中段部分的结构,叙述了中段部分拆卸装置的研制和使用情况。
Mine main drainage pump room is responsible for discharge of underground water an important task, is an important part of mine water prevention and control, is to ensure the safety of the key link. At present, most coal mines use single-suction, multistage and segmented horizontal centrifugal pumps. The main drainage pumps bear the task of draining the mine shaft. The wear and corrosion of the main drainage pumps are fast and require frequent maintenance of the pumps. This paper analyzes the structure of the middle section of single-suction, multi-stage and segmented horizontal centrifugal main drainage pumps commonly used in coal mines, and describes the development and application of the partial disassembly device in the middle section.
