In a steam turbine, once the starting oil solenoid valve 4WE6D62/EW230N9K4 has a response delay, it is a headache. Today, let’s take a look at the possible reasons for the response delay and how to solve it.

First, you have to look at the power supply. The 4WE6D62/EW230N9K4 solenoid valve must have enough power to respond quickly. If the power supply voltage is low, the suction force generated by the electromagnet is not enough, resulting in slow movement of the valve core and a slow response. You have to check the power supply voltage to ensure that it meets the working requirements of the solenoid valve.

The solenoid coil is the heart of the solenoid valve. If the coil is aged or damaged, such as the insulation layer is worn, the coil is short-circuited or broken, the magnetic field strength generated is weak, the valve core is difficult to move, and the response is naturally slow. Check the coil resistance regularly and replace it if abnormal. Don’t delay.

The valve core and valve seat are the components directly involved in the action. If there is wear between them, or impurities are stuck, the valve core will move with difficulty and the response time will naturally be extended. You need to clean the inside of the solenoid valve regularly, remove impurities, check the wear of the valve core and valve seat, and replace them if there are any problems.

The viscosity of the hydraulic oil also affects the response speed of the solenoid valve. If the oil viscosity is too high and the fluidity is poor, the resistance encountered when the valve core moves will be large, and the response will naturally be slow. You need to check the model and status of the hydraulic oil to ensure that it meets the working requirements of the solenoid valve, and replace or filter the oil if necessary.

The response of the solenoid valve is also related to the control signal. If the control signal is delayed or wrong, there will be problems with the instructions received by the solenoid valve, and the response will naturally not keep up. You need to check the control system to ensure that the signal transmission is correct. The controller and the line must be checked, and don’t let the signal problem hold you back.

If you encounter a response delay, don’t rush, you have to take it step by step. First check the power supply to ensure that the voltage is sufficient. Then check the solenoid coil to see if it is aged or damaged. Next, clean the inside of the valve and check the status of the valve core and valve seat. Then, check the hydraulic oil to ensure that the viscosity is appropriate. Finally, check the control signal to ensure that the transmission is correct. Every step must be meticulous, and only by finding the real cause can the right remedy be prescribed.

The response delay of the turbine start oil solenoid valve 4WE6D62/EW230N9K4 may be caused by power supply problems, aging of the solenoid coil, wear of the valve core and valve seat, excessive viscosity of the hydraulic oil, or control signal delay. For technical workers, being familiar with these possible reasons and mastering the troubleshooting and solution techniques are the key to ensuring the normal operation of the solenoid valve.
