Product description 2.2 Operating principle of compressor
Page 22 Operating instructions for S 40-3...S 150-3 series screw compressors
Oil circuit
The oil injected into the air end has the following function:
It dissipates the compression heat (cooling).
It seals the gaps between the rotors and between the rotors and the hous-
ing.
It lubricates the bearings.
Fig. 2.2: Components of the oil circuit
1 Compressed air-oil vessel
The oil separated from the compressed air through the force of gravity col-
lects in the compressed air-oil vessel. The system pressure forces it out
of the vessel into the air end.
2 Thermostatic oil control valve
Depending on the oil temperature, the thermostatic oil control valve either
allows the oil to pass through the oil cooler or through a bypass (e.g. in
the starting phase).
Thus the oil constantly maintains its optimum operating temperature.
3 Oil cooler (air or water cooled)
The oil cooler cools down the hot oil to operating temperature.
4 Oil filter
The oil filter traps impurities in the oil.
5 Air end
The injected oil returns to the compressed air-oil vessel together with the
compressed air. This is separated through gravity.
6 Drainage line
The air end suctions the residual oil which collects in the oil separator
back into the oil circuit via a drainage line.
