How is the inspection of the 5 ton water chiller carried out?

1. Inspection contents of 5t water chiller.

Check the LX -25°C ~ +30°C Recirculating Chillers, pipeline, cooling tower, pool and other places connected with the outside of the water-cooled chiller, and ensure that there are no impurities or foreign matters in the pipeline.

Check whether the wiring of the pressure gauge and the thermometer at the water side is normal. The pressure gauge should be 90 degrees perpendicular to the water pipe. The installation of the thermometer must ensure that its temperature detector can be directly inserted into the water pipe.

2. Inspection of cooling water and pipeline of 5t water chiller.

Check the water pipe for leakage, test run the cold water and cold water pump, and pay attention to the stability of water pressure. Pay attention to the pressure gauges at the inlet and outlet of the water pump. When the water pressure is stable, the reading of the pressure gauge and the inlet pressure difference change little.

Observe whether the working current of the pump is within the range of the rated working current. If there is a large deviation from the rated value, check the resistance of the system until the actual working current reaches the specified value.

3. Inspection of 5-ton water chiller.

Check whether the cooling tower/expansion water make-up equipment of the water chiller is normal, the automatic exhaust valve in the water system, the water pressure of the evaporator and condenser, to ensure the normal operation of the equipment. The inlet and outlet pressure of cooling water must be greater than 0.2 MPa.

Check the fan noise and the tightness of the fan belt to ensure that the connecting belt between the fan and the motor will not produce slipping and abnormal sound during operation. Check whether the switch of the float valve is sensitive and whether the water level in the water tank (water tank) is appropriate. If there is any problem, immediately adjust or replace it.
