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.
[pdf] Highly energy saving Comparing to non-variable speed screw air compressor, its average saving rate can be up to 50%; Super air displacement, its frequency is variable from OHz to 300Hz and the air displacement can be increased by as much as 28%; High efficient motor (IPM), its efficiency is up to 94.5%, reaching the rating of IE4.
[pdf] The rotary screw compressoris one of the most common types of rotary positive displacement compressor. They work with rotation as a rotary compressor should. They compress gas with the. They are: screw compressor and centrifugal compressor. Even though they are both used for the same category of demand, these two have their uniqueness and expertise; they cannot replace each other. They will certainly coexist for a long time.
