Abstract

The invention relates to a high-efficiency twin-screw compressor host, which is suitable for air compressors and belongs to the technical field of power transmission and control. The present invention is based on the variable lead technology. Its male and female rotors are designed as multi-lead screw rotor sections that conform to the meshing law. The lead of the screw rotor near the suction end is large, and the lead of the screw rotor near the exhaust end is small. Assembled structure. A high-efficiency twin-screw compressor host can obtain a larger internal compression ratio, which can increase the pressure of the output gas; it is a technical solution that can improve the efficiency of the compressor.

Description

Technical field [0001] The invention relates to a high-efficiency twin-screw compressor host, which is suitable for air compressors and belongs to the technical field of power transmission and control. Background technique [0002] Air compressors are general-purpose aerodynamic equipment, and twin-screw compressors have been widely used for their high reliability, long life, high degree of automation, convenient operation, strong adaptability, and easy mass production. As the core component of the air compressor, the main unit of the compressor has always been the goal pursued and expected by practitioners and users for its excellent quality and excellent performance. Its energy efficiency ratio is of great significance to enterprises and the national economy. [0003] The twin-screw compressor mainframes sold on the market are mainly divided into single-stage twin-screw compressor mainframes and two-stage twin-screw compressor mainframes. Its essence is that a pair of in...
