The three important structural parameters of the screw air compressor are: addendum speed and speed, rotor diameter and length-to-diameter ratio, and internal volume ratio, which will be explained in detail below.
[pdf] They use oil-free technology to produce pollution-free compressed air and are suitable for industries such as food and pharmaceuticals. They are designed to be energy-efficient and have the characteristics of low operating noise, low maintenance costs, long life, and stable and reliable.
[pdf] 1-1 Scope of Application This document covers procedures and methods of tests, examinations and inspections to be performed to the Screw Compressor which has been manufactured and supplied by s. This test is performed to ensure that there are no leaks in the piping, compressor, or other pressure containing parts of the package. All openings in the completed compressor package are plugged and the unit is pressurized with nitrogen to 350 psig.
