Some customers have applied the entire process of the constant temperature and humidity test box and found that their refrigeration and refrigeration compressors have always had too much current, and the large amount of current is very easy to destroy the internal parts of the machinery and equipment. They must find the reason and carry out the treatment. What caused the excessive current in the test chamber?
1. Enter the switching power supply working voltage of the constant temperature and humidity test box is too low, reducing the allowable working voltage value, which leads to excessive starting current.
2. The output power and current of the refrigeration compressor in the constant temperature and humidity test box have been expanded, but the "holding shaft" or "cylinder" has not been achieved, resulting in that the electric type cannot reach the rated speed ratio, making the refrigeration compressor impossible Rotate horizontally, resulting in excessive amount of starting current.
3. The refrigeration system software is endangered by external factors, such as the cooler is close to the wall, there is too much stain on the tube, the actual effect of natural gas condensate is poor, and the warm air cannot be released.
4. Sudden power failure or sudden call, the time interval is short, and under the condition that the high and low working pressure in the system software has not been balanced, the starting is difficult and the refrigeration compressor causes excessive current.
5. The refrigerant in the refrigerating compressor of the constant temperature and humidity test box leaks, the temperature cannot be reduced, and the motor continues to rotate, resulting in excessive current.
6. The starting relay is not working, which causes the working capacity of the overload protector of the constant temperature and humidity test box to flow out, resulting in excessive current.
