Before starting the stubble cooler, we should first check whether the motor of the machine is normal, and then start the equipment. During the inspection, the blower should be used to clean the dust and other dirt in the motor at the same time, and whether the wiring is qualified should be measured. If mechanical damage or spark burn mark is found in the motor, the necessary treatment should be carried out immediately.

用压缩空气或手动吹风机吹净电动机内部灰尘、电刷粉末等，污垢杂物。

Use compressed air or manual blower to clean the dust and brush powder inside the motor to remove the dirt.

拆除与电动机连接的一切接线，用绝缘电阻表测量绕组对机座的绝缘电阻。若小于0．5MΩ时，应进行烘干处理，酒厂用凉茬机，测量合格后再将拆除的接线恢复。

Remove all the wiring connected with the motor, and measure the insulation resistance of the winding to the base with an insulation resistance meter. If less than 0.5m Ω Drying treatment should be carried out, the distillery should use stubble cooler, and the removed wiring should be restored after the measurement is qualified.

检查凉茬机换向器的表面是否光洁，如发现有机械损伤或火花灼痕应进行必要的处理。

Check whether the surface of the commutator of the stubble cooler is smooth and clean. If any mechanical damage or spark burn mark is found, necessary treatment shall be carried out.

检查电刷是否严重损坏，刷架的压力是否适当，辽宁凉茬机，刷架的位置是否位于标记的位置。

Check whether the brush is seriously damaged, whether the pressure of the brush holder is appropriate, Liaoning stubble cooler, and whether the position of the brush holder is in the marked position.

根据凉茬机电动机铭牌检查直流电动机各绕组之间的接线方式是否正确，电动机额定电压与电源电压是否相符，电动机的起动设备是否符合要求，是否完好无损。

According to the motor name plate of the stubble cooler, check whether the wiring mode between the windings of the DC motor is correct, whether the rated voltage of the motor is consistent with the power supply voltage, whether the starting equipment of the motor meets the requirements, and whether it is intact.
