150HP two stage screw compressor with VSD

The 150HP Two Stage Screw Compressor consists of a two stage screw air-end, a permanent magnet synchronous motor, and a variable frequency control system. It currently represents the most energy-efficient and advanced technology within the screw air compressor industry. The two-stage screw air-end—the core component of this 110KW compressor—is a highly efficient unit designed to achieve optimal compression efficiency by dividing the overall compression process into two distinct stages. This two-stage compression approach reduces the compression ratio required for each individual stage, thereby minimizing internal leakage, enhancing volumetric efficiency, reducing the load on the bearings, and extending the service life of the air-end. In the first stage, intake air is compressed to an intermediate pressure, which then serves as the inlet pressure for the second stage of compression. The second stage further compresses the air, raising its pressure to the required discharge level. Durin…
