As we all know, buying a car is cheap and expensive. It is difficult to maintain the car, but if it is well maintained, it will also save a huge amount of money. Therefore, when people are buying refrigerated trucks, they must not simply choose low-cost, low-quality vehicles for a while, which will lead to troublesome follow-up maintenance and cost more money.

General ordinary refrigerated trucks are composed of chassis, refrigeration unit and car body. The regular maintenance of the chassis is not introduced here. The general service station can be solved with confidence. Today I mainly want to talk to you about how to use and maintain the refrigeration unit and the car body, so as to better extend the life of the refrigeration unit.

The quality of the refrigeration unit directly determines the temperature and insulation effect in the cargo compartment. The following points can be made to effectively extend the service life of the refrigeration unit:

1. Before starting the machine, wait until the engine is running to open the refrigeration unit before opening the refrigeration unit. Do not open the refrigeration unit before starting the engine. Be sure to check and maintain the work. Make sure that all fasteners and connection joints of the unit are solid and reliable. Tighten it tightly (check the compressor mounting and bracket fixing screws); Check whether the pulleys, belts, evaporator fans and other rotating parts are wrapped with flexible objects or contact with other parts, if there is immediate clearance; confirm the condenser, evaporator, heat dissipation If there is paper, thread, and a lot of dust attached to the sheet, foreign matter such as paper dust should be excluded, and the dust in the heat sink should be blown clean with high-pressure air; the cargo can not block the evaporator outlet and return air inlet and maintain the cargo compartment when loading. The cold air circulation is smooth to ensure there are no hot spots in the car.

2. When shutting down, shut down the refrigeration unit and turn off the engine first; when the cold storage unit runs for 100 hours, repeat the maintenance steps in 1; if it is not used for a long time, run the unit for 1-2 hours every 15 days. Then shut down, and secondarily check the stability of each line to ensure that the refrigeration unit is in normal working condition.

Car body maintenance is relatively simple, choose a regular manufacturer in the purchase, in the late use should pay attention to avoid hard objects hit the refrigerated compartment body, damage the sealing effect, resulting in decreased thermal insulation capacity, usually cherish use, wash Basic ventilation is no big problem.

Only the correct maintenance and maintenance of refrigerated trucks on time and on demand can effectively guarantee the normal use of refrigeration truck equipment in the work, so that it can be better invested in the later work.

1. More Efficient and Silent----Inverter Dual Fuel Generator can generate power according to actual demand, so they use less fuel; because of brushless alternator and special design, the generator produces less noise.
2. More Fuel Options----The fuel of Inverter Dual Fuel Generator can be natural gas(NG) and liquefied petroleum gas(LPG) and Gasoline. Thus, you can have more fuel options and wider application range.
3. High Quality Output----With 100% copper wire and brushless permanent magnet alternator(easy maintenance), advanced OHV engine, Inverter Gasoline Generator converts the AC output to DC and back to AC, which produces high quality electricity. 
4. Small and Light Design----Smaller engine and compact design lead to relatively light weight and portability.
5. VIGOROUS Inverter Dual Fuel Generator has ISO&CE Certificate.
