Refrigerated cars are durable consumer goods, the price is higher, the repurchase rate is low, if something goes wrong in the use, problems, they know the point of simple maintenance knowledge to save the trouble of running the repair shop, and the rest of the maintenance The cost, while also extending the useful life of refrigerated trucks, strengthens the daily maintenance and maintenance quality of vehicles and chillers. Therefore, it is very necessary to master basic refrigeration vehicle maintenance methods and techniques. First of all, take a look at the care and maintenance of the chassis of the refrigerated truck . When the chassis is being maintained, it is necessary to thoroughly clean the chassis and remove the mud from the chassis. It is better to wash it again with an oil-cleaning agent to make the chassis bright. Clean as new, then anti-rust care can begin. The refrigerated truck is lifted to the lifting rack for chassis cleaning and wiping. In this case, it is necessary to pay attention to the need to wait until the water on the tray is completely dry after washing, so that the rust-proof care can be performed. When performing care, be sure to keep the spray coating evenly to form a durable, uniform anti-rust coating. After completion of the work, air is allowed to dry for 5 to 10 minutes. The chassis rust treatment is completed. When cleaning, it is best to use non-alkaline detergents, washing powder to wash the body and chassis, otherwise it will affect the anti-rust effect and shorten the rust-proof time. Let's take a look at air-conditioning repair and maintenance, in general, the interval is one year, but also can be maintained at any time according to need. The refrigerated vehicle air conditioner used on vehicles is generally a single cold-opening type, and the refrigerant is mostly Freon. You can judge whether the refrigerant leaks by observing the inspection window. The method is: starting the engine, turning on the cooling switch, setting the temperature switch to the “cold†position, and turning the fan switch to maximum. If there is no bubble flow, the refrigerant leaks. Also observe the operating frequency of the air conditioner compressor. If it is faster than before, it may be insufficient fluorine. You can also test the high and low pressure of the air conditioner in a professional fluoridation repair shop. If it is high, determine whether you need to add fluoride. The air-conditioning system is generally equipped with a liquid-storage drier for the circulation ventilation filtration device and the refrigerant, so it must be remembered for cleaning and regular replacement during maintenance.
