1、 Why do refrigerated truck refrigeration units need maintenance

1. Protect the normal operation of equipment and ensure the quality of goods

(1) Long term use: When the refrigeration unit is used for a long time, the compressor is kept in operation for a long time, which can easily cause impurities to cause the compressor to lock and damage the refrigeration system. Generally, the maintenance of the refrigeration unit is based on the engine operating hours or engine mileage for protection and maintenance. Generally, the refrigeration unit is protected and maintained once every 500-700 hours or 2000 kilometers. Check the stability of the refrigeration system and adjust the refrigeration compressor belt and bracket, replace the dry bottle.

(2) Less frequent use: Customers can take some small measures to protect themselves, such as keeping the refrigeration unit working every two weeks for 10-15 minutes each time even if the refrigeration unit is not used for several months. Check the working condition of the refrigeration unit during the work process. Maintain once a year and properly inspect the refrigeration unit.

2. Extending the service life of refrigeration units and timely maintenance can reduce unnecessary repair expenses

(1) At present, when we use mechanical equipment, we usually repair it only after problems have been identified. If problems have not been identified, we approach it with the mentality of not needing to lose it and doing unnecessary maintenance. For refrigeration units that have not been maintained, subsequent problems will arise one after another, and there may be situations where one needs to be repaired after another. So timely maintenance can handle unnecessary repair expenses.

(2) After using the refrigeration unit for a period of time, there may be several problems to some extent: the refrigeration efficiency is slower than before, and sometimes the temperature cannot be lowered... This is similar to us humans. We need to deal with the symptoms that are about to appear in a timely manner. If not treated, we will get seriously ill. Therefore, we need to maintain the refrigeration unit in a timely manner to prevent serious illnesses from occurring.

(3) After maintenance, the service life of the refrigeration unit will be longer than before, which can slow down the unnecessary loss caused by frequent replacement of the refrigeration unit.

2、 How to maintain the refrigeration unit of a refrigerated truck

1. Check the condenser and clean it.

2. Check the evaporator and clean it.

3. Clean the system pipeline.

4. Check the working condition of the compressor to see if it needs to be cleaned

5. Check the condition of the compressor belt and bracket to see if the bracket needs to be corrected or the belt needs to be adjusted
