The Development and Progress of single screw compressor

    China's sustained rapid economic development, to compressor manufacturing business opportunities, but also put forward higher requirements. Many internationally renowned compressor manufacturers settled in the Chinese market, to our compressor manufacturing industry has brought unprecedented pressure. In both opportunities and challenges of the situation, how to quickly improve our compressor manufacturing technology, the creation of our own independent intellectual property rights of national brand, has become imperative. In this paper, the progress of a single screw compressor manufacturing technology aspects of the development process and to review the progress of a single screw compressor. And encourage one another.

    From 1975 to date, a single screw compressor in China has experienced a gradual progression from low tide to the normal state a tortuous process. At present, the potential advantages of a single screw this structure type has been revealed, recognized by the market acceptance as a flurry of positive displacement compressors on the market models.

    For over 30 years, in the course of development of a single screw compressor have encountered and solved technical problems in many areas, and improve the life of the star wheel piece is a prominent theme throughout the entire process.

    Star round piece and material life, lubrication, structural design as well as basic research have a relationship, and the manufacturing technology relationship with the star wheel worm tablets most closely, you can say life is as star-wheel piece manufacture worm and star wheel sheet Advances in technology and improved. Therefore, the development of manufacturing technology has become the most important prerequisite for a single screw compressor and core technology. Manufacturing Technology First Special Machines worm and star wheel sheet processing. Way to solve the plane: You can buy imported from abroad or purchased from domestic or self-design. Among them, the introduction or buy special machine is a shortcut. In the late 1970s and early 1980s had tried to buy from abroad, has worked with 辛麦恩, several times to discuss US CP companies, and finally due to technical blockade and minors. Many domestic machine tool plant and special machine tools are not willing to undertake the research institute commissioned the design and manufacture. Therefore, at the time of solving approach can only be a self-designed plane.

    Recalling the single screw compressor 30 years of development, divided into two phases.

    First, the first phase from 1975 to 1988

    1975 North First through first started to develop a single-screw air compressor, 76-year trial of 9 cubic single screw air compressor.

    Department of Xi'an Jiaotong University compressor some teachers began to single-screw compressors since 1978 in-depth study of many aspects, Shanghai 704 describes the evaluation of the US naval equipment sector single screw compressor and cold water made within a single screw Development and test of the air compressor. North through several times with a single screw inventor Xinmai En, US CP companies face communication, negotiation introduce and study abroad and so on. All of this makes about the single screw technology development staff to deepen understanding and increased awareness.

    At this stage, has developed a single screw compressor products manufacturers Sichuan (Jianyang) air separation plant, the depot Wenling, Zhejiang Province, Wuhan compressor plant in northern Jiangsu frozen Factory and other manufacturers. The plant for several years in the development of prototypes are trying to do a lot of good work, and some prototype performance data is still very good. But no merchandise available. Only one pass north of 9 cubic compressor a product reluctantly accepted by the market at this stage, and become commodities continued production and marketing. Summarize the main reason is to worm and star wheel chip manufacturing technology is not enough in-depth understanding of how to resolve differences and problems due to manufacturing techniques.

       First, the single-screw compressor manufacturing technology understanding. There is a process of understanding, the first expansion pack is the importance of the structural characteristics of the machine, only to find manufacturing technology really is the key. As the star wheel chip life is closely related to a variety of factors, such as floating star wheel structure, meshing vice material matching, lubrication power, especially meshing pair type line it is very important. Deputy meshing tooth profile is the star with the worm groove side wall in contact with the single screw compressor geometry of curved lines, in a single-screw compressor development staff has always been concerned about the type of line, look for small contact stress (contact line length, the line of contact dispersion), small abrasion (wear dispersion, easy to form a film), good contact, low leakage type of line. Needless to say, discuss the engagement mechanism, research and engagement is essential to improve the profile. However, for the development of a single screw compressor products, create better type of line is important, and is the most realistic. After failures and frustrations to perception, only experience in order to gradually mature. Development of personnel engaged in a single-screw encounter difficulties experienced varying degrees of confusion was recognized resolve processing methods, tools and equipment more practical, more urgent. This is the most important prerequisite for the development of a single screw compressor products. Over the years to solve the worm, star wheel sheet manufacturing technology as one of the main topics or main topics.
