Niro Soavi S.p.A
PRESSURE CHECK
The pressure gauge located on the front panel is used to measure the pressure
in the lubricating circuit.
During the final machine test optimal lubrication pressure is calibrated under
steady operating conditions; this value is largely affected by oil viscosity and
temperature so when the machine is started pressure is usually high and then
tends to decrease and become stable as the machine warms up with operation.
If pressure drops too low at high temperatures this may be due to problems with
the cooling system of the water/oil exchanger (where used) connected with
scaling or very high water temperature.
The water temperature must conform with the values given in Section 1 –
TECHNICAL SPECIFICATIONS.
The pressure in the lubrication circuit can be adjusted via the by-pass valve (F)
in the lubrication unit body (C) (figure 4.9.2):
FIGURE 4.9.2
− DO NOT REMOVE THE VALVE FROM THE BODY
− Loosen the lock nut and turn the Allen screw (Allen spanner) to reach the
correct pressure value
− Turn the screw CLOCKWISE to increase pressure and
COUNTERCLOCKWISE to reduce it
− Tighten the lock nut.
Adjustments must be made at high temperatures, with a value of approximately
5÷6 bar.
