【摘要】 高压防爆电机大部分故障是因为滚动轴承的损坏(隔爆面、工作温度等变化)。用叙述分析的方法,进一步阐述了轴承工作温度、主要隔爆面、使用维护等,从而得出了确保滚动轴承正常运行,对提高高压防爆电机的可靠性及相关场所的防爆安全至关重要的结论。更多还原

【Abstract】 The most faults for High-voltage Ex motor are caused by the rolling bearing damaged( such as, the abrasion of the flameproof joint, distinct change on temperature).This article describes the main factors which affects the working temperature for shaft bearing and flame-proof joints by overall analysis. It is concluded that proper operation of the rolling bearing is an essential point for improving the reliability of HV Ex motor and Ex safety operating in the hazardous area.更多还原
