    Causes of Misalignment (Excessive Deviation in Coaxiality) of Couplings in Horizontal Multistage Pumps and On-site Remedial Measures

    Causes of Misalignment (Excessive Deviation in Coaxiality) of Couplings in Horizontal Multistage Pumps and On-site Remedial Measures

    During the long-term operation of horizontal multistage pumps, improper coupling alignment and excessive coaxial deviation are frequent causes of excessive vibration, bearing overheating, seal leakage, and abnormal wear of coupling rubber blocks or tooth surfaces. These issues directly affect the safe and stable operation of the pump unit. Such problems are not caused by a single factor alone; rather, they span the entire lifecycle—from manufacturing and installation to operating conditions and maintenance. In this article, technical personnel from Changsha Zhonglian Pump Industry, a manufacturer of multistage pumps, draw on their practical experience in on-site installation and repair to share insights into the root causes of misalignment (excessive coaxial deviation) in horizontal multistage pump couplings, as well as on-site troubleshooting methods. They also provide actionable preventive and corrective measures for users' reference.

    There’s standing water at the bottom of the open-pit mine, and the switchgear room is still three kilometers away—so why did we choose a diesel engine to power the pump?

    There’s standing water at the bottom of the open-pit mine, and the switchgear room is still three kilometers away—so why did we choose a diesel engine to power the pump?

    Last rainy season, I was conducting equipment research at an open-pit coal mine in northwest China. The mine had already been excavated down to an elevation of -120 meters, and suddenly the water inflow at the bottom of the pit surged to 800 cubic meters per hour. The nearest substation is located on the ground-level industrial plaza, and running cables down there would require passing through three transport ramps. Given that the working face could shift at any time during the rainy season, it simply wasn't feasible to move the cables along with the shifting work area. In this article, Changsha Zhonglian Pump Industry—the manufacturer of diesel-engine pump units—will share a real-life solution provided to one of its customers: The open-pit mine’s bottom was flooded, yet the substation was still three kilometers away. So why did we choose a medium-flow diesel-driven pump?
