When the hydraulic valve station is operating normally, the control system 24 is connected to the power supply 1, the coil plug 21 is connected to the solenoid coil socket 5, and the power supply 1 generally uses a DC24V power supply. In the working process, the control system 24 sends out a control signal according to the received instruction, controls the relay 23 to be powered on and powered off, controls the electromagnetic coil to act after being processed by the functional module 22, further controls the hydraulic cylinder to act, and realizes the working process of the hydraulic valve table.

If the hydraulic cylinder does not respond after the control system 24 sends out the control signal, it indicates that the hydraulic valve station has a fault, and the fault type of the hydraulic valve station can be generally divided into a mechanical hydraulic equipment fault and an electrical equipment fault. The mechanical hydraulic equipment faults specifically comprise faults such as mechanical blockage of a valve core, hydraulic cylinder faults or blockage of external mechanical equipment; electrical equipment failure specifically refers to a failure of the solenoid coil and the solenoid coil socket 5, a failure of the control circuit 2, for example, a failure of the function module 22, or a failure of the cable of the control circuit 2, the coil socket 5.
