Circuit principle and connection method of Derek vibrating screen
The whole control cabinet does not work all the way or a few ways, the alarm light is on, check whether the fuse of this road is broken, whether the thyristor is damaged or shorted, and whether the electromagnetic vibrating coil is burned out,
A current in the circuit is not stable or small, in the protection of electromagnetic vibration coil regulation under normal conditions, check the way, SCR and wiring row does not contact the control cabinet, potential regulation, or limiting the potentiometer is bad, and can be controlled in the actual operation, a great relationship the electrical parameters of silicon,
The whole screen does not work, the whole screen does not work at this time, disconnect the panel switch, check whether the normal power supply, 220V AC voltage, check the circuit breaker is normal, then check the fifteenth relay is normal, under normal circumstances, circuit breakers and panel switch contact is not good,
There is a whole sieve road or several road should not work, treatment is measured with a multimeter and the power line road, the resistance between the controlled silicon anode, a normal whole sieve or several road, work is less than 1, if the circuit fails, should check the fuse, current meter, electric magnetic coil, to see whether it is in the open state, and then check the SCR control cabinet to the output line of the electromagnetic coil is open circuit, control cabinet adjusting potentiometer, whether open or at least state,
