    How can we prevent the mining multi-stage centrifugal pump from running dry?

    How can we prevent the mining multi-stage centrifugal pump from running dry?

    In mine shafts, it's common to encounter this situation: Just after a multi-stage centrifugal pump designed for draining underground water is started, an unusual noise from the motor is immediately heard. When you touch the pump casing, it feels scorching hot—only to discover upon disassembly that the impeller has already worn out due to dry running. Not only does this necessitate replacing parts, but it also delays the overall progress of water drainage in the mine. In fact, dry running doesn’t happen "suddenly"; with proper preventive measures taken in advance, such failures can easily be avoided. In this article, technical staff from Changsha Zhonglian Pump Industry, a manufacturer of mining-grade multi-stage pumps, will briefly discuss practical methods to prevent dry-running phenomena in these pumps, offering valuable insights for users to consider.
