Many users will encounter this unavoidable problem after using the water-cooled screw chiller for a long time. That is how to do a good job of maintenance to keep the  water-cooled screw chiller tidy and clean. It is not just a simple clean on the surface. In fact, the inside of the water-cooled screw chiller is The most difficult to clean are also easily missed by people.

1. The settings of the various protection devices of the unit have been set by the manufacturer. The user should not change it at will. If a failure occurs, press the stop button (the prompt light will go out), and then check the cause of the failure, and the humidifier Do not force the startup to run during troubleshooting.for a long time. That is how to do a good job of maintenance to keep the chiller tidy and clean. It is not just a simple clean on the surface. In fact, the inside of the chiller is The most difficult to clean are also easily missed by people.

2. After starting the machine, check whether the rotation direction of the fan is correct. If the rotation direction is normal, it can be used normally. If it is reversed, the power connection is reversed, and the phase sequence must be replaced before starting. To ensure a good heat dissipation effect, it is necessary to keep the surface of the cooling coil of the water-cooled screw chiller clean, ensure the air circulation around the machine, and the temperature is low, and regularly clean the cooling coil.

3. If it is not an emergency, please do not turn off the unit by cutting off the power supply; if the unit is out of service in winter for a long time, turn off the unit first, then turn off the main power supply, and drain the water in the chiller.

4. If the dehumidifier or high/low pressure switch frequently fails after the water-cooled screw chiller has been used for 6 months, or the cooling capacity is reduced, staff should be arranged to clean the condenser. If you have done this many times, the chiller goes to the fault alarm. Screw chiller maintenance and maintenance methods. Hand chain hoist daily inspection and maintenance precautions. Methods to determine the low oil pressure of diesel engines and troubleshooting methods. How to prevent scaling of evaporative condensers and how to maintain The heat conduction oil pump extends the service life of the vacuum pump.

5. Keep the computer room clean and well ventilated. Clean the condenser regularly to ensure the normal operation of the unit, keep the cooling tower clean, keep the air circulation and temperature around the water tower low, and prevent debris from entering the cooling tower to reduce heat dissipation efficiency.
