To avoid various faults occurs during working on an air compressor, you have to know the working principle of the screw compressor. What is a screw compressor and what is its basic working principle. Here we will look a bit closer at the screw air compressor technology. Screw compressors are perforce twinshaft rotating lobe machines. Rotary compressors and typesworking principleengineering. They work on the positive displacement principle with internal compression and are socalled. Principles of the rotary screw compressor the compressed air blog. Get help with the most common problems for rotary screw compressors. A given quantity of air or gas is trapped in a compression chamber and the space that it occupies is mechanically reduced, causing a corresponding rise in pressure prior to discharge.
How centrifugal pumps work working principle hvacr. Centrifugal pump basics how centrifugal pumps work working principle hvacr duration. Threedimensional view of dry screw compressor with driving gearbox working principle of dry screw compressors similar to the reciprocating compressor, the screw compressor is a positive displacement machine. Pdf advanced methods and tools for screw compressor design. The principal behind a twin rotary screw compressor was developed in the 1930s. Screw air compressor is one of the types of gas compressors which work on a rotary positive displacement mechanism.
It uses two asymmetrical rotors that are also called helical screws to compress the air. Rotary compressors are the another type of famous compressors. Theres a pretty good animation of the rotary screw animation process here and here. It is widely used in high pressure areas and is highly efficient, compared to the piston air compressors. Air compressors are used in manufacturing, welding, constructions, power plants, ships, automobile plants, painting shops, and for filling breathing apparatus too.

The working principle described here will apply to all screw air compressor manufactured by atlas copco, ingersoll rand, chicago pneumatics, elgi etc. The big difference is the design of the compressor elements, the part where the actual compression takes place. Injection screw air compressor is a singlestage twin screw compressor, efficient use of belts or coupling drive, turn the compressed air driving the host, the host by injection compression chamber for cooling and lubrication, compression chamber discharge air and oil mixture through the coarse and fine separation of two, will air in the oil separated from the resulting clean air. In many cases, a properly designed heat recovery unit can recover anywhere from 50 to 90 percent of this available thermal energy and put it to useful work heating air or water.
