1.2.1 Main Air Circuit System:
Composition: composed of air filter, intake valve, screw compressor, oil-air separator (including oil
content core) and minimum pressure valve, etc.
Operating principle: After removed of dust and impurities by the air filter, the external air enters the
intake cavity of screw compressor through the air intake valve and is mixed with the injected lubricating
oil during compression. The compressed the air-oil mixture is discharged into the air-oil separator
(air-oil tank), and more than 99% of oil is separated. Then, after being further separated by the
secondary oil-air separator (oil content core), the clean compression air enters the use system through
the minimum pressure valve.
Function: for air compression.
A. Air filter
The air filter is a dry paper filter, and the filter paper has a pore size of about 10 um. Its main function is
to filter the dust in the air.
B. Air Intake Valve
The intake valve is disc type. Through the opening, half opening and closing of the disc, the adjustment
of the intake air amount (i.e., exhaust amount) can be realized, thereby achieving the purpose of energy
saving.
