Its products are efficient, energy-saving, stable and reliable. The designed operating life under standard operating conditions is over 50000 hours. Screw compressor, also known as screw compressor. In the 1950s, oil injected screw compressors were applied in refrigeration devices. Due to their simple structure, few vulnerable parts, low exhaust temperature under large pressure differences or pressure ratios, insensitivity to the large amount of lubricating oil (often referred to as wet stroke) contained in the refrigerant, and good gas transmission regulation, they quickly occupied the use range of large capacity reciprocating compressors and continued to extend to the medium capacity range, widely used in refrigeration devices such as freezing, refrigeration, air conditioning, and chemical processes. Screw heat pumps based on it have been used in heating and air conditioning since the early 1970s, including air source type, water heat pump type, heat recovery type, ice storage type, etc. In the industrial sector, screw heat pumps are also used for heat recovery in order to save energy. Common products of screw compressors include screw air compressors, commonly known as screw air compressors, screw refrigeration compressors, and screw process compressors. The application of screw compressors is becoming increasingly widespread, with various types of open and semi closed screw compressors forming a series, and in recent years, a fully closed series of screw compressors has emerged. Twin screw compressors, abbreviated as screw compressors, consist of two rotors, while single screw compressors consist of one rotor and two star wheels. Their input power range for cooling and heating has developed to 10-1000KW. Based on a series of advantages of screw and single screw compressors, their research and development fields are very extensive, and there is great potential for performance optimization. The characteristics of Hanzhong compressors: 1. There are 13 basic models of Hanzhong compressors, with an average difference of about 20% in cooling capacity between adjacent models. The cooling capacity of the W-type ranges from 90kW to 780kW, and the cooling capacity of the H-type ranges from 74kW-638kW. 2. The single machine has a high horsepower, which can save manufacturing costs. 3. The parallel exhaust port adopts a bidirectional outlet design, which is convenient for customers to freely pipe [1]. 4. The noise is small, the overall vibration is small, and the service life is long. The combination design of 11 bearings and an alpha type axial thrust balance drum can increase the bearing life by 2.5-3.5 times. 5. The bearings are made of European and American brands, with high efficiency and low energy consumption. 6. The compressor structure is simple and reliable, with a wide range of accessory choices
