How to solve the common faults of the solenoid valve of the chiller system software?

    1. The power supply voltage is too low, causing the solenoid valve to fail to open and work normally;

    Solution: The power supply voltage of the DC solenoid valve can be adjusted.

    2. Poor contact of the power supply circuit, that is, a short circuit or a short circuit failure of the solenoid coil, which makes the smc pulse solenoid valve unable to work;

    Solution: You can use a digital multimeter to detect;

    3. The installation direction of the solenoid valve is reversed, that is, the fluid fluidity direction is reversed to the fluidity direction specified by the solenoid valve, so that the valve body is not closed strictly;

    Solution: Pay attention to the direction of the solenoid valve fluid and reinstall it.

    4. There is waste inside the solenoid valve, which causes the solenoid valve to be stuck, causing the transmission solenoid valve to be shut down improperly or unable to be turned off;

    Solution: disassemble and remove the dirt inside the solenoid valve

    5. The pressure difference between the import and export trade of the fluid exceeds the valve opening capacity, so that the solenoid valve cannot be opened;

    Solution: adjust the working pressure.

    6. The sealing gasket of the solenoid valve is damaged or the rotary vane pump is damaged, which causes many internal chambers to blow-by, which will cause insufficient indoor air working pressure, and make it difficult to open and close the forced valve.

    Solution: Disassemble and replace the sealing gasket of the solenoid valve and the rotary vane pump.
