Constant temperature and humidity test chamber-what to do if the compressor current is too large

In the daily test process, customers will find that the current of the refrigeration compressor of the constant temperature and humidity test box is large, which makes many users puzzled. The following are the points summarized by HUANYI instrument in many years of practice:

1. constant temperature and humidity test box The input power supply voltage is too low, and the voltage is too low to allow only work. This situation will occur. To

2. constant temperature and humidity test box Repair the short circuit between the compressor turns, but the fuse is not blown. To

3. The "secondary friction" of repairing the compressor destroys the smoothness of the friction surface, causing the compressor's power current to increase, but it has not reached the "holding shaft" or "cylinder jam", which may lead to failure to reach the rated The compressor cannot rotate normally, and the starting current is too large. To

4. The refrigeration system is affected by external factors, just like the condenser is close to the wall, the pipe is too dirty, the natural air condensing effect is poor, and the hot air cannot be emitted. To

5. constant temperature and humidity test box  Sudden power failure and sudden call, in the case that the high and low pressures in the system are not completely balanced, it causes great start-up difficulties and excessive current. To

6. The refrigerant in the compressor leaks, the temperature will be difficult to drop, the motor is running continuously, and the compressor current is too large. To

7. The starting relay fails and the thermal protector loses its capacity, resulting in excessive current.
