HYDRAULIC AND PNEUMATIC SYSTEMS
Figure 8.4-1 Hydraulic and pneumatic systems
9.1 Hydraulic lubrication system
The hydraulic lubrication system (Figure 8.4-1) of the compressor consists of:
-
Oil mist separator tank (A)
-
Oil mist separator filter (G)
-
Minimum pressure valve (B2)
-
Oil filter (C)
-
Oil cooling radiator (D
)
As you may notice, the lower portion of the oil mist separator tank (A) is used as
an
oil tank while the
minimum
pressure valve located in the upper part (B) operates as a support of the oil mist separator filter (G).
When starting the machine, the oil under pressure located in the tank starts flowing through the
tubing
into
the oil filter (C) and from there to the cooling radiator (D).
The cooled filtered oil then reaches the compressor (F) and is distributed
to the different parts (rotors,
bearings, etc.
)
which are t
hen
lubricated and cooled.
