In order to effectively solve the fault problems often occurring in the operation of underground water pumps in coal mines,based on three types of typical faults,namely,rotor misalignment,electromagnetic interference and impeller wear,the main causes of the above faults are analysed,and combined with the causes of the faults,the targeted fault handling solutions are put forward.From the practical effect,these three types of main faults have been significantly solved,so this fault handling experience helps to provide certain reference for future related work.
