4.3 - Flushing
Case flushing is compulsory when the motor has to continuously operate in the “Continuous operating area
with flushing” (pls. refer to the operating diagrams in the “Technical Catalogue” the motor type belongs to),
in order to ensure a minimum oil viscosity inside the motor case of 30 mm
2
/s.
Flushing may also be necessary out of the “Continuous operating area with flushing” when the system is
unable to ensure the minimum recommended viscosity level.
The oil temperature inside the motor case may be determined with excellent approximation
by measuring the motor case surface temperature t
A
and adding 3°C to it.
Here below there are flushing circuits that foresee the usage of flushing oil taken from the outlet line motor
to tank (external flushing).
In case the motor is requested to operate in bi-directional function, it is necessary to use a valve to perform
the connection between the outlet line and the motor case (flushing valve type “VFC”).
To measure the motor case leakage it is essential to disconnect the flushing system.
For all motor types the maximum allowed case pressure is 5 bar; in case higher case
pressure is required by the application, pls. contact Parker Calzoni s.r.l.
