Conclusion

In summary, the mechanisms leading to terminal failure include glass failure, poor electrical insulation, and abnormal operation of the compressor. Among them, there are multiple luring factors for terminal bursting, and the after-sales failure performance is similar. It cannot be determined the specific reason for the terminal bursting of the rotor compressor.

Based on the failure mechanism analyzed through experimental research, the following optimization and improvement conclusions are drawn:

1、 Regularly clean the evaporator and condenser to ensure the heat exchange effect of the two devices, and avoid liquid refrigerant generated due to blockage of the two devices or abnormal operation of the compressor from affecting the insulation performance of the wiring terminals.

2、 During the production process, strict management and control should be implemented to prevent metal foreign objects from entering the compressor, and shipment pressure testing equipment should be established to effectively detect unqualified products with pressure resistance performance, greatly reducing the risk of defective products leaving the market.

3、 The welding process of the air conditioning system or compressor manufacturing process adopts inert gas protection welding to ensure that the inner surface of the pipeline does not oxidize during the welding process, and to prevent welding oxide skin from entering the compressor and causing terminal failure due to contact with the terminal.

4、 Establish a dust-free manufacturing environment with constant temperature and humidity, improve the sealing of the junction box cover, and eliminate the phenomenon of poor insulation of the compressor due to moisture and other issues.

5、 Silicone ceramic structure terminal blocks can effectively improve the performance of the terminal blocks. It is recommended to use silicone ceramic structure terminal blocks for rotary compressors.
