Correct operation
Only the correct use and operation of refrigerated trucks can ensure the good delivery and preservation of goods. Because refrigerated trucks are specially used for temperature-sensitive products, temperature assurance is the key to refrigerated trucks. If used or handled improperly, the goods will not be stored or shipped in perfect condition.
preventive maintenance
In our normal use process, the maintenance and maintenance of the vehicle and the refrigerator are inseparable. Only correct maintenance and maintenance of the equipment on time can ensure the normal use of the equipment and prolong the service life of the equipment. Usually the chassis engine is maintained and maintained according to the mileage, while the refrigeration unit is maintained and maintained according to the engine operating hours. Usually the refrigeration unit is maintained and maintained every 500~700 hours, 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 and whether there is any leakage in the refrigeration system; some brands of refrigeration units (such as American refrigeration units) Wang) In order to meet the needs of environmental protection, minimize the damage to the environment, and reduce the emission of harmful substances, synthetic or semi-synthetic engine oil is used to replace ordinary engine oil, thereby extending the maintenance time of the engine. Usually, maintenance is performed every 2,000 hours. Therefore, the discharge of waste oil is reduced. In addition, scientific experiments have proved that by using this high-end oil, not only the wear and tear of the engine can be reduced, but also the fuel consumption of the engine can be reduced.
How to maintain a refrigerated truck?
As a special vehicle, refrigerated trucks must pay attention to some matters before driving to prevent unnecessary troubles on the way. It is recommended to carry out the following inspections before loading goods each time:
1. The refrigerated truck fuel diesel or gasoline supply must be sufficient to keep the engine running at least to the next check point.
2. Refrigerated truck engine oil The engine oil level is supplied at the (full) mark, do not overfill (replace once a year).
3. Refrigerated truck coolant Check the coolant level gauge to see if the amount of coolant is correct, and the pointer should be within the white range. If the coolant level is in the red range, add coolant to the coolant tank. Usually the cooling liquid is a mixture of ethylene glycol and water (different proportions are used according to the actual conditions of the product), and it should provide protection from freezing at -34°C. NOTE: Do not open the lid of the coolant tank when the coolant is hot.
4. The terminals of the refrigerated truck battery must be firm and free of corrosion. The electrolyte should be at the full mark.
5. The belt must be good and good and adjusted to an appropriate degree of tension. 13mm sag in center of span between pulleys.
6. Electrically inspect all electrical connectors in the electrical control circuit to ensure they are securely fastened. Wires and terminals should be free of corrosion, burns, cracks, or moisture.
7. Structural visual inspection of the unit for leaks, loose or broken parts and other damage.
8. The installation gasket of the gasket unit should be firmly pressed and in good condition.
9. The refrigerated vehicle coil condenser and evaporator coil should be clean and free of dirt.
10. Defrost Drain Check the defrost drain hose and fittings to make sure they are clear.
11. When the cargo compartment is loaded, the cargo cannot block the outlet and return air of the evaporator, so as to keep the cold air circulation in the cargo compartment unobstructed, so as to ensure that there will be no hot spots in the compartment.
Therefore, scientific maintenance and maintenance can not only ensure the integrity of the equipment, but also reduce operating costs.
