摘要
将煤矿专用防爆电动机旋转轴动密封结构设计为IP67防护等级,解决受电动机体积限制、密封件与转轴摩擦温度高,散热条件差,应用环境特殊等潮湿、积水恶劣工况下的煤矿井下专用电机完全防水的问题,从而降低电动机进水的可能性,提升设备运行的可靠性。
Design dynamic sealing structure of rotation axis for explosion-proof motor specially for coal mine as IP67 protection grade to solve completely waterproof problem of special downhole motor for coal mine under severe operating conditions such as high friction temperature between sealing element and rotation axis owing to limited volume of motor,poor heat dissipation conditions,special application environment,moisture and water accumulation,etc.so as to further reduce water entering possibility of motor and improve operation reliability of the equipment.
