When the company used the high and low temperature box to carry out experiments, it found that the current of its refrigeration compressor has been too large, and it is very easy to damage the internal parts of the machine and equipment through the large current. The reason? I will give you a detailed analysis below.

There are several levels that lead to the overcurrent of the refrigeration compressor in the high and low temperature box. Below is a summary of some commonly used reasons:

1. The power supply voltage of the input high and low temperature box is too low, reducing the working voltage value in the allowable work, and then causing the running current to be too large.

2. The output power and current of the compressor in the high and low temperature box are expanded, but the "shaft-holding" or "clamping cylinder" is not achieved, which causes the electric type to fail to reach the rated speed ratio, so that the compressor cannot rotate horizontally, resulting in the starting current is too big.

3. The refrigeration unit of the high and low temperature box is affected by external factors. For example, the cooler is close to the wall, and there are too many stains on the pipe. Of course, the actual effect of gas junction is poor, and the warm air cannot be released.

4. Sudden power failure or sudden phone call, the time interval is short, and when the working pressure in the operating system has not been balanced, it will make the operation difficult and cause the compressor to cause excessive current.

5. The refrigerant in the compressor of the high and low temperature box leaks, the temperature is difficult to reduce, and the motor continuously rotates, resulting in excessive current.

6. The start relay fails, causing the overload protector of the high and low temperature box to flow out of the working capacity, resulting in excessive current.
