Industrial Low Temperature Chiller Maintenance

Industrial Low Temperature Chiller Maintenance

The maintenance of industrial low-temperature chillers is an essential point. Only by maintaining the machine regularly will there be no aging or non-working phenomenon. If you let it go, then the service life of this equipment will be greatly shortened. Let’s take a look at the maintenance methods of industrial low temperature chillers:

1. The settings of various protection devices of the industrial low-temperature chiller have been set by the manufacturer, and users should not change them at will.

2. Regularly check whether the cooling water system of the chiller is normal, whether the cooling tower fan and sprinkler shaft are in good operation, whether the water replenishment of the built-in water tank of the chiller is normal, and regularly check whether there is leakage of the chiller refrigerant, you can refer to the high and low pressure on the front panel of the host. Table parameter determination.

3. When the equipment fails and alarms and stops, you should press the alarm stop button first, and then check the cause of the failure. Remember not to force the machine to start before the fault is eliminated.

4. When the device is in use, if it is not an emergency, do not turn off the device by cutting off the power at will. If the chiller is out of use for a long time in winter, turn off the machine first, then turn off the main power supply, and drain the water in the chiller.

5. Keep the machine room clean and well-ventilated, and clean the condenser regularly to ensure the normal operation of the equipment.

6. After the air-cooled chiller is turned on, check whether the direction of the fan is correct. If the direction is normal, it can be used normally. If it is reversed, the power wiring is reversed, and the phase sequence must be changed before starting. It is also necessary to ensure a good heat dissipation effect, which is to keep the surface of the cooling coil of the chiller clean, ensure that the surrounding air is circulated and the temperature is low, and clean the cooling coil regularly.

7. The water-cooled chiller must keep the cooling tower clean, keep the air circulation around the water tower and the temperature low, and avoid sundries entering the cooling tower to reduce the heat dissipation efficiency.

8. The system should be cleaned when the chiller is used for six months, once a year. The main cleaning parts include: cooling water tower, cooling water pipe and condenser part to ensure better cooling effect. If the chiller has been used for 6 months, the dehumidifier or the high and low pressure switch frequently fails, or the cooling capacity is reduced, it is necessary to ask professional maintenance personnel to repair it.

The above are some methods of maintaining industrial low-temperature chillers. If we do the work of maintaining chillers in daily life, it can not only improve the working efficiency of the chiller, but also prolong the life of the chiller, reduce the operation danger, and make the chiller more durable.
