使用的立式长轴没来,故障为系启动不了
添加时间:2019.12.07

江西一锅厂, 使用的立式长轴没来,电机功率为I5kW.故障为系启动时,有时能启动来,有时就不能启动。

解决过程:现场泵盘车灵活,电机接线正确,电压正常,但泵输送的水中含有大量的泥沙,使密封环之间的摩擦现象较为严重。后来找来了电工师傅了解,钢厂开关柜上的保护电流调得较小,又加上泥沙原因,启动电流较大,造成了泵有时能启动,有时不能启动。建议在安全范围内适当调大一些保护电流,泵就很容易启动了。渣浆泵

安徽快3开奖结果In Jiangxi No。1 boiler plant, the vertical long shaft used did not come, and the motor power was i5kw。 When the fault is system startup, sometimes it can be started, sometimes it can not be started。

Solution process: the pump on site is flexible in turning, the motor wiring is correct and the voltage is normal, but the water delivered by the pump contains a lot of sediment, which makes the friction between the sealing rings more serious. Later, I found an electrician to understand that the protection current on the switch cabinet of the steel plant was adjusted to a small value. In addition, due to the sediment, the starting current was large, which caused that the pump could be started sometimes and could not be started sometimes. It is suggested that the protection current be properly increased within the safe range, so that the pump can be started easily. Slurry pump
