Before starting the stubble cooler, we should check whether the machine's motor is normal before starting the equipment. When checking, we should use the hair dryer to clean up the dirt and debris in the motor, and also measure whether the wiring is qualified. If we find mechanical damage or spark burning marks in the motor, we should do the necessary treatment immediately.

電機(jī)運(yùn)用前的查看方法

Viewing method before motor operation

1、用壓縮空氣或手動(dòng)吹風(fēng)機(jī)吹凈電動(dòng)機(jī)內(nèi)部塵埃、電刷粉末等，污垢雜物。

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

2、撤除與電動(dòng)機(jī)銜接的一切接線，用絕緣電阻表丈量繞組對(duì)機(jī)座的絕緣電阻。若小于0．5MΩ時(shí)，應(yīng)進(jìn)行烘干處理，丈量合格后再將撤除的接線恢復(fù)。

2. Remove all connections connected with the motor and measure the insulation resistance of the winding to the base with an insulating resistance meter. If it is less than 0.5M, it should be dried and the wiring removed will be restored after the measurement is qualified.

3、查看涼茬機(jī)換向器的外表是否光潔，如發(fā)現(xiàn)有機(jī)械損害或火花灼痕應(yīng)進(jìn)行必要的處理。

3. Check whether the exterior of the commutator of the stubble cooler is clean or not. If mechanical damage or spark burns are found, the necessary treatment should be carried out.

4、查看電刷是否嚴(yán)重?fù)p壞，刷架的壓力是否恰當(dāng)，刷架的方位是否坐落標(biāo)記的方位。

4. Check whether the brush is seriously damaged, whether the pressure of the brush holder is appropriate, and whether the direction of the brush holder is in the direction of the mark.

5、根據(jù)涼茬機(jī)電動(dòng)機(jī)銘牌查看直流電動(dòng)機(jī)各繞組之間的接線方式是否正確，電動(dòng)機(jī)額定電壓與電源電壓是否相符，電動(dòng)機(jī)的起動(dòng)設(shè)備是否符合要求，是否完好無(wú)缺。

5. According to the motor nameplate of the stubble cooler, check whether the connection mode between the windings of the DC motor is correct, whether the rated voltage of the motor is in accordance with the voltage of the power supply, whether the starting equipment of the motor meets the requirements, whether it is intact or not.
