I. Protection of Industrial Chillers:
1. Check the voltage is normal, lack of phase.
2. Check and record operating current.
3. Check the oil level and oil temperature are normal.
4. Check the compressor for abnormal noise and abnormal vibration.
5. Refrigerant system test.

6. Overall test and test.
7. Measure and record whether the high and low pressure and temperature are normal.

8. High-pressure 1.5 MPa for political parties and 0.45 MPa 4 for low pressure, check if the chain control circuit device is loose and the chiller is aging.

9. Regularly check whether the quality of the cooling water is the same as that of the cooling water. When the water quality of the water source becomes dirty and dirty, change the water source in time.
II: Maintenance of Industrial Chillers
1. Basic Cleaning:

The main task is to clean the panel and filter mesh. Generally, it should be cleaned once a month. The panel can be cleaned with clean water or neutral detergent. After washing, it should be dried and then loaded (do not sun or barbecue). Remember not to use more than 40 degrees Hot water, it is strictly prohibited to use gasoline, volatile oil, mixed solvent, friction powder, disinfectant and detergent to wash the plastic parts such as the panel. The dust filter net can filter the dust in the air. If the dust blocks the mesh, the amount of air entering and leaving the air will be reduced, and the cooling effect will be reduced. When the filter is cleaned, first remove the filter dust net according to the instructions, brush it with a soft brush, then rinse with water, dry it with a soft cloth or dry in a cool place, and then press the instructions to close the filter. On the filter network.
