SCREW AIR COMPRESSOR
WORKING PRINCIPLES
3.
Oil Flow
There is a residual quantity of oil present in the air end. This residual oil provides lubrication for the first few
seconds. Once the compressor starts and pressure of around 2.0 bar [30 psig] is achieved in the separator,
positive pressure on the surface of the oil in the tank (item ) forces oil into the air end thereby insuring
lubrication.
During the first few minutes of operation the oil will not be heated to its' ideal working temperature (60 to 70°C
or 140 to 158°F). In order to rapidly achieve the desired temperature, the oil circuit has a thermostatic valve
(item

) with two circulation routes.
Below 80°C or 176°F, the oil flows into the compressing unit through an oil by-pass (item
thermostatic valve prevents oil flow through the oil cooler.
The oil warms up quickly from the heat of compression and very quickly reaches the ideal operating
temperature.
At 80°C or 176°F the thermal element expands, displacing the piston inside the valve that progressively opens
the oil by-pass and allows oil flow through the oil cooler (item
In addition to rapid warming of the oil the thermostatic valve prevents oil cooling to temperatures below 80°C
or 176°F. By regulating oil flow through the cooler and the by-pass, the valve ensures that all of the oil injected
into the air end is at the ideal working temperature. This reduces the condensation of water vapor in the
separator and tank which maintains the quality of the oil and reduces air system contamination.
The oil from the two circulation routes (cooler and by-pass) mixes and is filtered (item
injected into the compressing unit.
The oil deposited at the bottom of the separator element is continuously evacuated back to the inlet side of
the air end through the oil return dipper (item
