efficiency analysis of oil injected twin screw air compressor

Efficiency Analysis of Oil Injected Twin Screw Air Compressor

Oil injected twin-screw compressors are widely used for medium pressure applications in many industries. Low cost air compressors can be adopted for compression of helium and other gases, leading to significant cost saving. The efficiency, delivery rate of the compressors (medium and small size) has been analyzed and presented in the study.

Analysis of the leakage in a water-lubricated twin-screw air

Fig. 4 shows the simulated and experimental p-V diagrams of the water-lubricated twin-screw air compressor at 3000 rpm and 5400 rpm. It can be seen that the pressure at the end of compression is lower than discharge pressure, which suggests that the compressor worked on the under-compression condition.
