Cement brick electromechanical magnetic cabinet

The indicator light on the solenoid directional valve of the high quality qt12-15 cement brick making machine door is on, the pressure gauge shows the pressure, but there is no oil pressure on the oil pipe. Cause of failure: the solenoid directional valve is blocked, resulting in no oil pressure or very low oil pressure on the oil pipe in the oil cylinder of the material door. Removal method: cleaning liquid solenoid directional valve or replacement of valve parts. Fault reason: solenoid valve coil burned out, cement brick mechanical and electrical magnetic valve can not reverse. Removal method: replace the solenoid valve coil. Observe whether the solenoid valve spool is attached? Unplug the solenoid valve coil plug, press the brick machine material door open or material door close when the toggle switch, and then use a screwdriver to top the material door solenoid reversing valve valve core, the material door can move, can confirm the solenoid valve solenoid coil damage (or use a multimeter to test the coil resistance, further judgment). Material door output terminal lamp does not light brick machine did not output voltage cement brick machine factory | cement hollow bricks machine price Phenomenon: the indicator light of the input terminal of PLC can be on, the indicator light of the output terminal is not on, the brick machine has no output voltage. Cause of failure: improper setting of parameters, material door opening time is set to zero, or material door opening times is zero. If this is the reason, no burning brick machine PLC output point will flash. Elimination method: cement brick machine will be material door opening time set to 1.0 seconds, or material door opening times for 1-2 times. Cause of failure: PLC output terminal is damaged. Elimination method: if the PLC output terminal is damaged, remove the maintenance or replace the PLC can be.
