As the core component of Chongqing refrigerated trucks, the compressor requires maintenance and upkeep as a top priority for refrigerated truck users. How to extend the service life of the compressor? The selection of lubricating oil is also quite skillful.

Lubricating oil plays a role in lubrication, sealing, cleaning, heat dissipation, rust prevention, etc. inside the compressor, providing protection for the compressor and greatly improving the performance of the refrigeration system of refrigerated trucks.

There are many selection criteria for compressor lubricating oil, so when it comes to the issue of compressor oil return, the main requirement is to ensure that the lubricating oil maintains good fluidity at low temperatures. Therefore, it is necessary to choose a low pour point to avoid viscosity and prevent backflow to the compressor at low temperatures.

Secondly, it is important to consider the brand. There are many lubricants on the market that have quality assurance and reasonable prices. When choosing, one should deliberately seek affordability and choose a reliable brand to truly protect the compressor.

The simple way to detect lubricant quality issues is to look at the color. The color of mineral lubricating oil should be transparent with a slight bright yellow. Refrigerated truck manufacturers remind everyone that if the lubricating oil you purchase is cloudy and dark in color, it indicates that the lubricating oil contains impurities and high paraffin content.

The color of lipid synthetic lubricating oil is bright yellow, slightly darker than mineral oil. As its kinematic viscosity increases, the color becomes darker, and it will turn bright yellow with red brown.
