6 FAQs about [Single screw air compressor evaluation report]

What is the performance analysis of oil injection-free type single screw compressor?

This paper explains the method of the performance analysis of the oil injection-free type single screw compressor. This model predicts the swept volume, the port area, the efficiency, the torque and the pressure, etc. The measurement technique and the result of the screw rotor internal groove pressure measurements are explained.

Can a computer predict the performance of a single screw compressor?

It is possible to predict its performance and to calculate the force and the torque change, etc., by using a computer. The internal groove pressure of the single screw compressor is measured using digital memory, a personal computer and piezo type pressure sensors and compaired with the analysis. It is proved that the analysis is satisfactory.
