Description

Technical Field

[0001] This utility model belongs to the field of compressor technology and relates to a twin-screw air compressor. Background Technology

[0002] Screw air compressors are oil-injected single-stage twin-screw compressors, which are divided into single-screw air compressors and twin-screw air compressors. They use high-efficiency belt drive to drive the main unit to rotate and compress air. The compressed air in the main unit is cooled by oil injection. The air and oil mixture discharged from the main unit is separated into coarse and fine stages to separate the oil from the compressed air, and finally clean compressed air is obtained.

[0003] Twin-screw air compressors operate at high temperatures, requiring large fans for cooling. To facilitate fan installation, a protective frame is installed on the outside of the air compressor. This not only facilitates fan installation but also provides some protection for the unit and improves safety. However, the current method of using a protective frame is inconvenient for the installation, disassembly, and maintenance of the internal air compressor, reducing installation and maintenance efficiency. Therefore, improvements are needed. Summary of the Invention
