冷庫在使用的過程中難免會出現一些小的故障,為了不影響冷庫的使用,快速解決麻煩,那么學會一些常見的維修知識,就可以在最短的時間內排除冷庫故障減少損失。
Cold storage in the use of the process will inevitably be some small faults, in order to use does not affect the cold storage, quickly solve the trouble, then learn some common maintenance knowledge, can reduce the loss of cold storage fault excluded in the shortest time.
1、長時間不啟動或長時間開機不停止或庫溫不到就停機。
1, long time does not start or boot long time does not stop, or less than the temperature of the library will stop.
(1)、控制器的參數設定有誤,重新設定即可。
(1) the parameter setting of the controller is wrong and can be reset.
(2)、溫控失靈。
(2) the temperature control is out of order.
(3)、電器損壞。
(3) electrical damage.
(4)、檢查冷凝器上是否有污物,散熱不好會導致制冷機冷凝壓力過高,為了保護壓縮機,在壓力控制器的作用下機器停止運轉,等到散熱良好后,按一下壓控器上黑色復位按扭,機器即可自動恢復運行。
(4) if there is dirt, check the condenser, the heat is not good will cause the condenser pressure is too high, in order to protect the compressor, the machine in the pressure under the control of stop, wait for good heat, click on the button reset voltage controller black machine can automatically resume operation.
2、冷庫設備初期運轉機組: 冷庫設備初期運轉機組要經常觀察壓縮機的油面及回油情況及油的清潔度,發現油臟或油面下降要及時解決,以免造成潤滑不良。
2, the initial operation of compressor refrigeration equipment: cold storage equipment early operation units should always observe the compressor oil and return oil and oil cleanliness, oil or dirty oil drop should be resolved in a timely manner, so as to avoid bad lubrication.
3、冷庫由于隔熱或密封性能差,導致冷量損耗大 。
3, cold storage due to heat insulation or poor sealing performance, resulting in large cooling capacity.
4、經常觀察冷庫設備的心臟壓縮機運行狀態:檢查其排氣溫度,在換季運行時,要特別注意系統的運行狀態,及時調整系統供液量和冷凝溫。
4, always observe the cardiac operation condition of the compressor refrigeration equipment: check the exhaust temperature, in the season when running, should pay special attention to the operation state of the system, the timely adjustment system for fluid volume and condensing temperature.
5、平時應通過觀察儀表的變化、聽機器運轉的聲音、摸機器的溫度變化等方法觀察壓縮機的運行狀態。發現壓縮機有串氣等現象應及時修理或更換。
5, usually by observing the instrument changes, listen to the sound of machine operation, touch the machine temperature changes and other methods to observe the running state of the compressor. There is the phenomenon that the compressor leakage should be promptly repaired or replaced.
冷庫隔熱性能差是由于管道、庫房隔熱墻等的保溫層厚度不夠,隔熱和保溫效果不良,它主要是設計時保溫層厚度選擇不當或施工時保溫材料質量差所導致的。
The cold heat insulation performance is poor because of the thickness of the insulation layer, heat insulation wall pipe warehouse is insufficient, heat insulation effect, it is mainly the thickness of the insulation layer design or construction of improper selection of insulation material caused by poor quality.
或保溫材料的保溫防潮性能有可能被破壞導致保溫層受潮、變形,甚至糜爛,其隔熱保溫能力下降,庫防冷量損耗隨之增大,庫溫下降明顯減緩。
Or the insulation insulation moisture-proof performance may be damaged insulation damp, deformation, and even erosion, its insulation ability, anti cold base loss increases, temperature decline slowed down significantly.
