The Road to Technical Change from Column Valves to Valves and Reductors

As early as 1998, Xue Liangliang was acutely aware of the need to open up a new type of automotive air-conditioning energy-saving environmental protection refrigeration compressor. To open the market gap, only work hard in the new word, in order to allow automotive air-conditioning refrigeration compressor innovation.

In the course of product technology research and development, he believes that in order to innovate new types of automotive air-conditioning compressors, it must pass technical barriers. To this end, he conducted countless trials and experiments. He asked related experts for critical and difficult technical issues. Through unremitting efforts, the original “column valve” was replaced by the “valve and resetter” device, which achieved better sealing of the compressed gas in the cylinder, which greatly reduced the power consumption and achieved the maximum Good cooling effect. In the material, he also made adjustments to ensure the quality of the gas seal.

The original automotive air-conditioning refrigeration compressors are often unable to separate or separate oil and gas, resulting in the loss or scrapping of internal compressor components. After repeated practice, he solved the very complicated problem of oil and gas separation.

The utility model has the advantages of simple structure, small volume, light weight, effective volume ratio of up to 95%, continuous gas transmission, no surge phenomenon, and lower power consumption than the first, second and third generations of refrigeration and air conditioning. compressor. The most important feature is that it can work normally in high-speed operation. Due to the bold improvement of the oil inlet device inside the machine, it solves the problem of burning due to the inability to enter the oil and improves the cooling effect. The service life of the compressor. When the speed of the refrigerating and air-conditioning compressor reaches 3,500 rpm, the engine is continuously oiled, does not burn, and keeps running.

New automotive air-conditioning energy-saving environmental protection refrigeration compressor innovation in a number of technical indicators, such as rolling rotary compressors used needle roller bearings. Now that the ultra-thin plane has been added to both ends of the compressor spindle, the compressor spindle has played a role in protecting and stabilizing the work. The slider is the core component of the compressor. Its high frequency of motion makes the spring that pushes it easy to break. After being improved and innovative, the slider of the new spring device is used to extend the service life of the spring.

Practical new-type automotive air-conditioning energy-saving environmental protection refrigeration compressor, is ideal for installation in Changan Star, Changan Suzuki, Tianjin Xiali, FAW Jiabao, Geely and other domestic cars, which undoubtedly played an important role in promoting the development of today's auto industry.

It is understood that a number of car manufacturers are currently discussing with him on investment development and production issues.
