1.一体机冷干机不启动
①检查冷干机是否正确通入电源。
②检查零线是否缺失。
③检查开关是否失灵。
④检查高低压保护器是否跳保护。
⑤检查蒸发压力表压力是否正常。
⑥检查压缩机是否震动，如有发热震动检查启动电容是否有问题。
1. The all-in-one cold drying machine does not start
①Check whether the cold and dry machine is correctly connected to the power supply.
② Check whether the zero line is missing.
③ Check whether the switch fails.
④ Check whether the high and low pressure protector is jump protection.
⑤ Check whether the pressure of evaporation pressure gauge is normal.
⑥ Check whether the compressor vibration, such as heat vibration check whether there is a problem with the
starting capacitor.
2、故障现象:机组排气温度高(超过 100 ℃)
①机组冷却剂液位太低(应该从油窥镜中能看到，但不要超过一半)；
②油冷却器脏；油过滤器芯堵塞；温控阀故障(元件坏)；
③风扇电机故障：触发风机交流接触器，检查风机是否旋转
④温度传感器故障：当机器运行时，观察显示器温度是否有数字跨度很大乱跳的情况
⑤排风管道不畅通或排风阻力(背压)大，散热出风口处有遮挡物
⑥环境温度超过所规定的范围(38℃或 46℃)；
⑦如遇到更换变频器换线导致高温，检查电机按主机提示方向是否正转
解决办法
①更换冷却液以及油滤
②用高压空气吹扫散热器以及机箱内部门板过滤网
③如遇风扇到 95 度以上或者显示器显示风机启动时风机没有按时启动，及时联系售后人员
2, fault phenomenon: unit exhaust temperature is high (more than 100 ℃)
1. the coolant level of the unit is too low (it should be visible from the oil speculum, but not more than half);
2.Oil cooler dirty; Oil filter core blocked; Temperature control valve failure (bad components);
3.Fan motor fault: trigger the ac contactor of the fan to check whether the fan is rotating
4. Temperature sensor fault: when the machine is running, observe whether the display temperature has a large
digital jump
5.The exhaust pipe is not smooth or the exhaust resistance (back pressure) is large, and the heat dissipation air
outlet has shelter
6. Ambient temperature exceeds the specified range (38℃ or 46℃);
7. In case of high temperature caused by cable replacement of frequency converter, check whether the motor is
running in a positive direction as prompted by the host
