隔爆型船用三相异步电动机在海上平台的危险区域使用非常广泛，而其电机故障较多发生在轴承、轴瓦等方面。渤海某平台中型高压隔爆型电机在正常停机备用后再次起动，在起动过程中发现电机振动、电流突然增大且出现异常噪音。停机检查，排除电机轴承等方面的问题后，判断出现了刨轴故障。分析了该中型高压隔爆型电机轴承室隔爆面与轴发生刨轴故障的原因，并阐述了修复受损的电机隔爆面及转子轴的方法。
Flameproof three-phase asynchronous motor is widely used in dangerous areas of offshore platforms. For this kind of motor, failure mostly occurs in bearings or bearing shells. On an offshore platform in Bohai, a medium-sized high-voltage flameproof motor was shut down normally and then restarted. In the restart process, the motor vibrated, showing a suddenly increasing current and abnormal noise. Inspection showed that there was no problem in the motor bearing, so plane shaft failure was considered. The reasons for the failure of the flameproof surface and shaft of the bearing chamber of the medium-sized high-pressure flameproof motor are analyzed, and the method of repairing the damaged motor's flameproof surface and rotor shaft is described.
