1.常见故障的诊断方法(1)压力或冷媒量不正常此故障可通过干燥瓶上面的观察孔诊断。若观察孔有少许气泡,说明冷媒量合适;若气泡过多或者无气泡都可能是冷媒不足或者无冷媒。最科学的检查方法还是通过压力表测试。低压端压力若低于68.9 kPa,说明系统冷媒不足;高于275.8 kPa,冷媒可能过多。冷媒不足或过多,压力长期过高或过低,都可能引起压缩机运动部件的润滑和冷却条件恶化,最终导致
1. Common Fault Diagnosis (1) The pressure or refrigerant is not normal This fault can be drilled through the observation hole above the hole diagnosis. If the observation hole a little bubble, indicating the appropriate amount of refrigerant; if the bubble is too much or no bubble may be lack of refrigerant or no refrigerant. The most scientific method of inspection or through the pressure gauge test. If the pressure at the low pressure side is lower than 68.9 kPa, the system refrigerant is not sufficient; if it is higher than 275.8 kPa, the refrigerant may be excessive. Inadequate or excessive refrigerant, long-term pressure is too high or too low, may cause compressor lubrication of moving parts and cooling conditions deteriorate, eventually leading to
