问:我公司喷煤管一次风机转速650,电流335安,但跳停开启后一次风机转速增加了100转,电流才315A,请帮忙分析原因。

答:该风机电机是变频电机,如果在没有调整频率的情况下转速增加则应该检查变频系统。从你提供的情况有可能是喷煤管管道内有堵塞情况或个别阀门失灵,造成出风阻力较大,使转速不能达到应该的转速,同时电流也增加,估计这也是跳停的原因,重新开启后堵塞的地方可能因其他原因到得到消除,从而使其正常运转。有机会的话还是检查一下喷煤管管道及各控制阀门是否失灵等因素。仅供参考。

问:离心风机运行过程中,靠近电机端轴承端盖温度升高较快,是什么原因?

答:1、检查轴承使用情况,轴承是否使用周期已到;2、检查轴承润滑油是否需要添加或更换。以上回答仅供参考。
