How to Properly Maintain and Overhaul the Refrigerated Truck?

Hubei Hongfeng Special Vehicle Manufacturing CO., Ltd. tells you the maintenance of commercial refrigerated trucks is vital. Only when the equipment in the refrigerator truck is maintained correctly on time can the normal use of the equipment be guaranteed and the service life of relevant equipment in the refrigerator truck be extended. Usually, the refrigerated truck refrigeration unit is maintained every 500hrs ~ 700hrs, and the oil filter element, fuel filter element, and air filter element need to be replaced. And pay attention to check the tightness of the belt, refrigeration system leakage, etc.

Refrigerating units in order to adapt to the requirements of environmental protection, to minimize the damage to the environment, reduce the emissions of harmful substances. We remind you that you had better use synthetic oil or semi-synthetic oil to replace the ordinary oil, which can prolong the engine maintenance time, usually a maintenance every 2000hrs. It also can reduce the waste of oil emissions. Besides, scientific experiments have shown that the use of this high-end engine oil can not only reduce engine wear but also reduce engine fuel consumption. Therefore, Hubei Hongfeng Special Vehicle Manufacturing CO., Ltd. tells you that scientific maintenance can not only ensure the intact equipment but also reduce operating costs.

Generally speaking, the daily maintenance of the compartment body of the refrigerator vehicle is mainly reflected in: the inspection of the outside surface of the compartment, the inspection of the inside surface of the compartment, the inspection of the inside and outside edges and corners of the compartment, the inspection of the interior floor of the compartment, as well as the inspection of the internal lighting, cooling air outlet, etc. Do not scratch the external surface of the refrigerated compartment, otherwise, on the one hand, it will reduce the pressure bearing capacity of THE FRP, more prone to aging deformation, and on the other hand, it will cause the leakage of the internally filled polyurethane, thus affecting the insulation performance of the compartment.

Refrigerator inner surface of maintenance to the adjustment of the temperature control, do not make the compartments freezes the body surface if the air humidity is big, Hubei Hongfeng Special Vehicle Manufacturing CO., Ltd. remind you to package good refrigeration products, especially aquatic products packing seal can reduce moisture to evaporate to compartments inside the body, reduce the possibility of inside the refrigerator freezing. If there is a layer of ice on the inside surface of the refrigerated vehicle, after each transport of goods, it should be promptly removed with a deicing scoop to prevent the ice from becoming thicker, Hubei Hongfeng Special Vehicle Manufacturing CO., Ltd. reminds you that if you do not only affect the compartment storage space but also increase the vehicle's weight, increase fuel consumption. Likewise, care should be taken to avoid damage to the inner surface of sharp goods or containers.

It is recommended to carry out the following maintenance before each loading of the refrigerated truck:

1. The fuel supply of the refrigerated vehicle must be sufficient to ensure that the engine runs to the next maintenance point at least;

2. The engine oil level of refrigerator car should be at the (full) mark, do not overfill;

3. Check whether the amount of coolant is correct.

4, the refrigerator car battery terminal must be firm, with no corrosion.

5. The electrolyte should be at the full mark;

6. The belt must be in good condition and adjusted to an appropriate degree of expansion and tightness. The span between the belt wheels should be 13mm in the center of sag;

7. Ensure that all electrical connectors in the electrical control line are fixed firmly;

8. Wires and wiring terminals shall be free from corrosion, fire, cracking, or moisture.

9. Visually check whether there is leakage of the unit, whether parts are loose or broken, and whether the installation gasket of the gasket unit is pressed;

10. Coil pipes of coil condenser and evaporator of commercial freezer trucks shall be clean and free of dirt;

11. Ensure the defrost drainage device is unblocked.
