1、检查电源：配电箱上没有电或显示屏不显示。请检查冷库的专用闸是否失灵。
2、冷库不制冷或制冷效果差。检查制冷机的冷凝器上是否脏。检查库内蒸发器上是否积霜过厚。检查制冷剂是否渗漏(用肥皂水涂在管路连接处，有气泡生成说明制冷剂渗漏)。并请专业人员补充制冷剂并对渗漏处进行处理。检查冷库门的密封是否完好并排除之。检查冷库的制冷机是否工作。检查冷库的电脑控制器的参数设定是否正确并重新调整。检查冷库的控制器是否失灵并更换之。检查库内堆放物品是否留有足够的间隙并疏通之。
3、机器运转时有异常的噪声，请停机检查，是否是振动引起或机械故障。配电箱里有异常的噪声，这是交流接触器发出的声音，是由于接触器的运动部件局部不灵活，请断电后来回按一下接触器的吸铁即可消除噪声。
4、制冷机启动频繁或长时间不启动或长时间开机不停止或库温不到就停机。
5、合闸后冷库配电箱没有反应，而三相电正常。请检查零线，是否有220V电压。冷库的零部件(各种阀件、控制器)都已设定好，没有用户需要调节的零件。振动筛常见故障排除途径安全阀几种常见故障及原因反应釜的日常维护板框压滤机设备检查高周波熔接机的日常维护和保养滤油机的故障的分析和解决措施。
Linshun for you to introduce cold storage maintenance skills: 1, check the power supply: There is no power distribution box or display screen does not show. Please check the dedicated brake of the cold storage to see if it is out of order. 2. The cold storage does not refrigerate or the refrigerating effect is bad. Check the condenser of the refrigerator for dirt. Check whether the evaporator in the warehouse is too thick frost. Check for refrigerant leakage. Apply soapy water to pipe connections. Air Bubbles are formed to indicate refrigerant leakage. And ask a professional to replenish the refrigerant and treat the leak. Check the seal of the cold storage door and eliminate it. Check whether the refrigerator is working. Check the parameters of the computer controller of the cold storage are set correctly and readjusted. Check the controller of the cold store for malfunction and replace it. Check if there is enough space for the items to be stored in the warehouse and clear it. 3, the machine running abnormal noise, please stop check, whether it is vibration or mechanical failure. There is abnormal noise in the distribution box, this is the voice of the AC contactor, is due to the contactor parts of the movement is not flexible, please power cut back click on the contactor magnet can eliminate the noise. 4. The refrigerator starts frequently or does not start for a long time or does not stop for a long time or the warehouse temperature does not stop. 5. The cold storage distribution box does not respond after closing, but the three-phase power is normal. Please check the zero line for 220V voltage. The spare parts of the cold storage all kinds of valves, controllers have been set up, there is no need to adjust the user's spare parts. Common trouble-shooting ways of vibrating screen safety valve several common troubles and their causes daily maintenance of the plate and frame filter press equipment of the reaction kettle check the daily maintenance of the high-cycle welding machine and the failure analysis and solution of the maintenance of the oil filter.
