Abstract

To study the effect of oil injection parameters on the performance of the twin-screw air compressors and to provide a reference for optimizing and improving the overall performance of such air compressor

a mathematical model of the oil-injected twin-screw air compressor was developed to study the effect of oil injection volume and oil injection temperature on the performance of the air compressor and the accuracy of the model was verified by comparing the simulation re

sults with the experimental results. The results show that

there is an optimal oil injection volume for a twin-screw air compressor to achieve the best adiabatic efficiency and specific power

and such volume decreases as the speed increases(from 3 000 r·min

-1

to 4 400 r·min

-1

)and increases with the back pressure(from 0.7 MPa to 1.0 MPa). In addition

the increase of oil injection temperature makes the adiabatic efficiency of the compressor decrease and the specific power increase

which leads to the deterioration of the compressor performance. Thus

the oil injection temperature should be as low as possible while ensuring the exhaust temperature. At the same time

there is a significant effect of injection parameters on leakage and power consumption. In particular

with the increase of the injection temperature(from 303.15K to 323.15K)

the leakage of each leakage channel shows a increasing trend

and the friction loss shows a decreasing trend

while with the increase of injection volume(from 0.5 m

·h

-1

to 1.5 m

·h

-1

)

the leakage shows a decreasing trend

and the friction loss shows a rising trend. This research provides a useful reference for optimizing the performance of the oil-injected twin-screw compressors.
