1、檢查電源：配電箱上沒有電或顯示屏不顯示。請檢查冷庫的專用閘是否失靈。

2、冷庫不制冷或制冷效果差。檢查制冷機的冷凝器上是否臟。檢查庫內蒸發器上是否積霜過厚。檢查制冷劑是否滲漏(用肥皂水涂在管路連接處，有氣泡生成說明制冷劑滲漏)。并請專業人員補充制冷劑并對滲漏處進行處理。檢查冷庫門的密封是否完好并排除之。檢查冷庫的制冷機是否工作。檢查冷庫的電腦控制器的參數設定是否正確并重新調整。檢查冷庫的控制器是否失靈并更換之。檢查庫內堆放物品是否留有足夠的間隙并疏通之。

3、機器運轉時有異常的噪聲，請停機檢查，是否是振動引起或機械故障。配電箱里有異常的噪聲，這是交流接觸器發出的聲音，是由于接觸器的運動部件局部不靈活，請斷電后來回按一下接觸器的吸鐵即可消除噪聲。

4、制冷機啟動頻繁或長時間不啟動或長時間開機不停止或庫溫不到就停機。

5、合閘后冷庫配電箱沒有反應，而三相電正常。請檢查零線，是否有220V電壓。冷庫的零部件(各種閥件、控制器)都已設定好，沒有用戶需要調節的零件。振動篩常見故障排除途徑安全閥幾種常見故障及原因反應釜的日常維護板框壓濾機設備檢查高周波熔接機的日常維護和保養濾油機的故障的分析和解決措施。

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.
