　　1、 What is a refrigerator and what is its function?

　　Chiller is a kind of mechanical equipment which uses compressor to change the pressure change of refrigerant gas to achieve low temperature refrigeration. The compressor used is different from the general air compressor because of its different service conditions and compressed working medium. According to the differences in the structure and working principle of the refrigerator, it is similar to the air compressor, and can also be divided into piston type, screw type, centrifugal type and other different forms. Refrigerator is one of the most important parts of compression refrigeration equipment. The refrigerator is made up of compressor, condenser, evaporator, drying filter and expansion throttle valve in series, in which a proper amount of refrigerant is injected, and the electric appliance controls the compressor operation according to the needs of the environment to achieve the purpose of refrigeration and heat transfer. The operation rules, lubrication characteristics and fault maintenance are introduced in detail.

　　The refrigeration lubricating oil plays an extremely important role in the refrigeration system: it not only lubricates the moving friction parts of the refrigeration machinery, but also takes away the friction heat generated in the working process of the compressor. At the same time, it can reduce the exhaust temperature and improve the working efficiency of the refrigeration equipment. The lubricating oil fills the oil seal and the clearance between the cylinder and the piston to prevent the leakage of the refrigerant and the high and low pressure gas flow For the compressor with energy regulation, the change of lubricating oil pressure is used to regulate the unloading mechanism, and the lubricating oil plays a dynamic role here. In addition, the lubricating oil can also remove impurities and wear debris from the system.

　　2、 Treatment of moisture content in the refrigerator.

　　The lubricating oil discharged from the refrigerator (hereinafter referred to as the secondary oil) contains ammonia, a small amount of water and a small amount of mechanical impurities. The water in the refrigeration oil will mix with ammonia to intensify the chemical change of the oil, make the refrigeration oil deteriorate and corrode the metal; the mechanical impurities in the refrigeration oil will aggravate the wear of the friction surface of the moving parts and block the oil filter. Under the catalysis of high temperature and metal, refrigerator oil contacts with gasket, refrigerant, water and air, which will cause decomposition, polymerization and oxidation reactions, and generate pitch like carbonized coke. These substances can destroy the air tightness of the air valve, and block the filter and expansion valve after entering the pipeline system. Therefore, the regeneration treatment of lubricating oil is to remove the moisture and mechanical impurities in the secondary oil, and also can not contain carbonized coke.

　　3、 Recovery of refrigerator oil treatment of oil purifier

　　The specific processing methods are as follows:

　　1. Treatment method of refrigerator oil:

　　Features of vacuum oil purifier: strong ability to remove impurities, large area and deep-seated precision filter material can remove fine particles in oil, and equipped with strong magnetic filter to remove iron impurities. The unique dehydration and degassing system adopts three-dimensional evaporation technology and multi-level oil-water separation technology to rapidly separate water and gas in oil. The heating system adopts optimized pipeline design to ensure even heating and stable oil temperature. Precise filtering system, multi-level filtering and encryption step by step, large amount of pollution. It can effectively remove the impurities in the oil and configure the automatic detection function of filter element contamination.

　　2. Use the oil filter equipment provided by professional oil purification equipment manufacturers:

　　Zhongjing brand refrigerator lubricating oil filter is used for vacuum separation and micro water treatment of excess free water and emulsified water in oil. Regular filtration and purification of refrigeration oil can effectively prevent the generation of water gas, mechanical impurities and carbonized coking substances. After the secondary oil regeneration treatment, it can be used again after being put into the oil drum, which reduces the operation cost of the refrigeration equipment. The recovery and regeneration of the refrigeration oil is an important work content. It is necessary for the operators to understand the correct oil discharge operation and the regeneration treatment of the oil, which meets the needs of production and economic operation.
