螺杆式压缩机常见的产品有螺杆式空气压缩机俗称螺杆空压机，螺杆式制冷压缩机及螺杆式工艺压缩机。螺杆式压缩机应用越来越广泛，各种开启式和半封闭式螺杆压缩机已形成系列，后来又出现全封闭系列螺杆压缩机。双螺杆压缩机简称螺杆压缩机，由两个转子组成，而单螺杆压缩机由一个转子和两个星轮组成，它们制冷和制热的输入功率范围已发展到10-1000KW，基于螺杆式和单螺杆式压缩机一系列优点，其研究和开发领域十分广泛，性能优化潜力大。
Screw compressor common products are screw air compressor commonly known as screw air compressor, screw refrigeration compressor and screw process compressor. Screw compressors are more and more widely used. A variety of open and semi closed screw compressors have formed a series, and then there are totally closed screw compressors. Twin screw compressor is called screw compressor for short, which is composed of two rotors, while single screw compressor is composed of one rotor and two starwheels. Their input power range of refrigeration and heating has developed to 10-1000kw. Based on a series of advantages of screw compressor and single screw compressor, their research and development fields are very extensive, and their performance optimization potential is great.
