    Practical Procedures for Priming and Bleeding Air from a Wear-Resistant Multistage Centrifugal Pump Prior to Startup in Coal Mines (Specifically for Main Drainage Systems)

    Practical Procedures for Priming and Bleeding Air from a Wear-Resistant Multistage Centrifugal Pump Prior to Startup in Coal Mines (Specifically for Main Drainage Systems)

    The wear-resistant multistage centrifugal pump for underground coal mines is the core equipment of the main drainage system. The priming and air-venting procedures performed prior to startup directly determine whether the pump unit can reliably draw in water, and they are also critical operational and maintenance steps for preventing cavitation damage, excessive vibration, and dry-running wear. In view of the special operating conditions in underground coal mines—namely, explosion-proof requirements, deep head, and handling of particle-laden media—this paper presents, based on practical experience from the field, a set of straightforward, on-site methods for priming and venting wear-resistant multistage centrifugal pumps used in coal mining, tailored to the real-world operational needs of mine pumps.
