The failure characteristics of large pump units are that the influence is great, the reasons are complicated, it is difficult to observe and the failure rate is hard to determine. The main failures of large pump units are as follows: burn out of thrust bearing liner of the motor, failure of stator and rotor coil insulation of the motor, wear-and-tear of guiding bearing and shaft neck of the pump, breakdown of adjusting mechanism of the pump blade, and pump cavitation. The reasons of main failures are studied in design, structures, installation and operation etc.
