Failure and troubleshooting method of explosion-proof starter in metallurgical plant

 Explosion-proof starter is made of steel shell plate with ac contactor, thermal relay corresponding wire configuration, and at the time of use, it should start with the stop button switch, but also cooperate with right hand control signal cable connection, when press the start button, switch on the motor power to achieve self-locking function through the auxiliary contact, contact when press the stop button will automatically disconnect, thus the power to cut off the electric appliances and automatic unlock.

If pulse valve open, explosion-proof starter can't shut down, this time you need to repair or replace explosion-proof starter, if there no problem to see small orifice is completely blocked, if blocked, you need to remove the dirt, pulse valve normally closed a controller under the condition of no signal, you need to overhaul the system of the control system, if there is no problem, need to look at the riot starter have failed or vent have been blocked, immediately if there is a problem to repair or replace the flameproof starter.

If the pulse valve normally closed appeared under the condition of no signal control system, access control system will be needed, if there is a signal system, but the flameproof starter malfunction or vent is blocked, this time you need to repair or replace the flameproof starter, if have no problem only the last point, the diaphragm is damaged, directly replace the diaphragm.

The above are most common problems and elimination methods of explosion-proof starters. It is necessary to be more careful when using and pay attention to the maintenance after power failure.
