Hydraulic solenoid valve is broken several fault phenomena

First, fault phenomenon 1: can not control the hydraulic actuator

The hydraulic solenoid valve is broken, and the most common fault phenomenon is the inability to control the hydraulic actuator. In this case, the hydraulic actuator will not work properly, resulting in the equipment can not complete the work task.

Solution: First check whether the hydraulic solenoid valve is normally energized and working, if the solenoid valve is normal, you need to check whether the sensor and control system related to the solenoid valve is normal, and then test the hydraulic actuator after troubleshooting to ensure that it can work normally.

Second, fault phenomenon two: can not maintain the pressure of the hydraulic system

The hydraulic solenoid valve is broken, which will affect the normal operation of the hydraulic system. If the solenoid valve does not correctly control the flow of hydraulic oil, the pressure of the hydraulic system will not be able to maintain normal, thus affecting the efficiency of the hydraulic equipment.

Solution: First check whether the hydraulic solenoid valve is blocked or damaged, and if there is a fault, the solenoid valve needs to be replaced or repaired in time. At the same time, check whether the pressure gauge of the hydraulic system is working normally. If it is not normal, it is necessary to replace or repair the pressure gauge to ensure that the pressure of the system is normal.

Three, fault phenomenon three: hydraulic system overpressure

The hydraulic solenoid valve is broken, which may cause the pressure of the hydraulic system to exceed the rated value, resulting in the activation of the hydraulic system overpressure protection device. If the overpressure protection device does not work properly, it will cause serious damage to the equipment.

Solution: Check and replace the hydraulic solenoid valve to ensure that the valve can accurately control the pressure of the hydraulic system. At the same time, check whether the overpressure protection device of the hydraulic system works normally, and it is necessary to replace or repair the overpressure protection device in time.

Four, fault phenomenon four: the noise of the hydraulic system becomes larger

The hydraulic solenoid valve is broken, which may lead to an increase in the working load of the oil pump and other hydraulic components in the hydraulic system, and then make the whole system produce noise.

Solution: Check whether the hydraulic solenoid valve works normally, replace or repair the faulty solenoid valve in time, and carry out a comprehensive inspection and maintenance of the hydraulic system to ensure that the work load of the system components is balanced.
