- 5.9) OLEOPNEUMATIC PLANT
(Fig. 3) --
-- 5-9-1) COMPRESSOR LUBRICATION SYSTEM --
The system includes the oil separator tank (Z), the thermostatic valve (U) on
which, at the entrance, the oil filter (V) and the oil cooling radiator (M) are mounted.
As shown in fig. 4 the lower part of the oil separator tank (Z) acts as an oil tank,
will the filtering part is situated at the top which separates the air from the oil.
On starting up the machine, the pressure generated by the compressor, makes
the oil inside the tank flow through the conduit in the direction indicated by the arrow. A
thermostatic valve (U) is positioned along the route, which according to the actual oil
temperature, conveys it all or partially to the cooling radiator (M), more specifically:
- at temperatures of below 65
c, the thermostatic valve remains open and the
oil in circulation is directly injected into the compressor, without going through the radiator
(M).
FIG. 3
During the working cycle the oil is heated and when it reaches a temperature of
65
C, the thermostatic valve (U) begins to close, thereby making it necessary for part of
the oil to go through the cooling radiator (M).
