冷库在使用的过程中难免会出现一些小的故障，为了不影响冷库的使用，快速解决麻烦，那么学会一些常见的维修知识，就可以在最短的时间内排除冷库故障减少损失。

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、长时间不启动或长时间开机不停止或库温不到就停机。

1, long time does not start or boot long time does not stop, or less than the temperature of the library will stop.

(1)、控制器的参数设定有误，重新设定即可。

(1) the parameter setting of the controller is wrong and can be reset.

(2)、温控失灵。

(2) the temperature control is out of order.

(3)、电器损坏。

(3) electrical damage.

(4)、检查冷凝器上是否有污物，散热不好会导致制冷机冷凝压力过高，为了保护压缩机，在压力控制器的作用下机器停止运转，等到散热良好后，按一下压控器上黑色复位按扭，机器即可自动恢复运行。

(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、冷库设备初期运转机组: 冷库设备初期运转机组要经常观察压缩机的油面及回油情况及油的清洁度，发现油脏或油面下降要及时解决，以免造成润滑不良。

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、冷库由于隔热或密封性能差，导致冷量损耗大 。

3, cold storage due to heat insulation or poor sealing performance, resulting in large cooling capacity.

4、经常观察冷库设备的心脏压缩机运行状态：检查其排气温度，在换季运行时，要特别注意系统的运行状态，及时调整系统供液量和冷凝温。

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、平时应通过观察仪表的变化、听机器运转的声音、摸机器的温度变化等方法观察压缩机的运行状态。发现压缩机有串气等现象应及时修理或更换。

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.

冷库隔热性能差是由于管道、库房隔热墙等的保温层厚度不够，隔热和保温效果不良，它主要是设计时保温层厚度选择不当或施工时保温材料质量差所导致的。

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.

或保温材料的保温防潮性能有可能被破坏导致保温层受潮、变形，甚至糜烂，其隔热保温能力下降，库防冷量损耗随之增大，库温下降明显减缓。

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.
