Distribution of maintenance procedures

 (1) the maintenance single phase electric motor of landing the ark: take out the drawer cabinet,drawer cabinet of automatic air switch,contactor,tighten all of the terminal,contact uneven parts with a flat file file,not spring gasket must be paid to the replacement,check whether the primary loop line ear asynchronous motor contact,end of the line insulation are in good condition,connection-peg presence of the ablation phenomenon,after the dust cleaning,back into the power distribution cabinet,close the air switch,check whether the control parts and instructions normally.(2) the maintenance of PGL ark: after the blackout,first check whether the automatic switch,isolating switch is good,tighten all wiring,contact has ablation parts with a flat file file.Spring washer should be replaced,check whether the main return route ear is well connected firmly.

Terminal insulation is reliable,check whether the zero line insulation layer is damaged,aging,loose contact,test grounding of cabinet put oneself in another's position,sending after cleaning dust,check www.facebook.com/dongfeng.motor the secondary loop.(3) maintenance procedures for capacitance ark: first will play to stop switch capacitance ark,then disconnect the total power switch capacitance ark,with 25 MMZ wires through the resistance by the capacitor to discharge to check and tighten the contactor,reactor,capacitor terminals,terminal control line are in good condition,the grounding device meets the requirements,contact of permanent magnet motor the file ablation and clean the tank components,then closing check discharge lamp and automatic compensation system is normal.All of the above maintenance as a result,should be written in maintenance records.
