External maintenance of refrigerated truck

1、 Pay attention to wash the vehicle frequently. To keep a small refrigerator car clean, it is not enough to wipe it with a cloth. It should be cleaned frequently. Due to the special vehicle to contact with some harmful gas or salt, acid, alkali and other corrosive dust, it is necessary to clean the vehicle frequently.

2、 Pay attention to the application of soft cotton yarn or soft towel, not hard cloth. When colored dust falls on the car body, the dust should be cleaned in time. Otherwise, such substances may seep into the paint layer, making the surface tarnish.

3、 Pay attention not to wash the vehicle in strong sunlight. After cleaning, do not dry the water and do not expose to the sun.

4、 Pay attention to vehicles in coastal areas or chemical pollution areas, wash with soft water every week. Do not use detergent, washing powder and other high alkaline detergent. When using cleaning agent, special cleaning agent or alkaline soap should also be used. Otherwise, the grease on the paint layer will be washed off when the dust is washed off, which will cause the paint surface aging and tarnishing.

5、 Pay attention to clean the car in time after rain. It's better to wipe off the rain in time for the small refrigerated car that has been drenched in the rain, especially after being drenched in the rain, it will be exposed to the sunlight without wiping, which has a great impact on the paint surface.

Maintenance method of refrigerated truck body

Under the premise of stable operation of refrigeration unit, it is very important to maintain the continuous temperature if it can provide stable refrigeration conditions. Most of the materials of the refrigerator car insulation box choose the inside and outside FRP panel, because the FRP panel has unique advantages.

Generally speaking, the daily maintenance of the refrigerator car insulation body is mainly reflected in the inspection of the external surface of the car, the internal surface of the car, the internal and external edges and corners of the car, the internal floor of the car, the internal lighting, the cooling air outlet and so on. For the external surface of the refrigerated compartment, do not scratch the compartment. On the one hand, it reduces the ability of FRP to bear pressure and is more prone to aging deformation. On the other hand, it will cause the leakage of polyurethane filled inside, which will affect the thermal insulation performance of the compartment.

For the maintenance of the inner surface of the refrigerator car, it is necessary to adjust the temperature control, and do not make the surface of the compartment freeze. If the air humidity is relatively high, try to pack the refrigerated products, especially aquatic products. The packaging and sealing can reduce the evaporation of water to the interior of the compartment, and reduce the possibility of freezing inside the refrigerator car. If there is a layer of ice on the inner surface of the refrigerator car, it should be removed with a de icing shovel in time after each transportation of goods, so as to prevent the ice layer from becoming thicker and thicker, which not only affects the storage space of the compartment, but also increases the weight of the vehicle and fuel consumption. In the same way, attention should be paid to the interior to avoid the damage of sharp goods or packing cases to the interior surface.

Finally, the maintenance of the internal electrical equipment, because the electrical equipment of the refrigerated car body is in a relatively high humidity and low temperature environment. To prevent the occurrence of various short circuits caused by exposed power lines, but also to prevent unnecessary damage to the lighting equipment that will heat due to alternating cold and hot.
