Hydraulic Connections
!
WARNING
Check that the values of hydraulic supply available are compatible with those reported on
the identification plate of the actuator.
NOTICE
The connections should be made by qualified staff. Use pipes, fittings and connections
appropriate as for type, material and dimensions.
Connect the actuator to the hydraulic feed line with fittings and pipes in accordance to the
plant specifications. They must be sized correctly in order to guarantee the necessary oil
flow for the operation of the actuator, with pressure drops not exceeding the maximum
allowable value. The shape of the connecting piping must not cause excessive stress
to the inlets of the actuator. The piping must be suitably fastened so as not to cause
excessive stress or loosening of threaded connections, if the system undergoes strong
vibrations. Every precaution must be taken to ensure that any solid or liquid contaminants,
which may be present in the hydraulic pipework to the actuator, are removed to avoid
possible damages to the unit or loss of performance. The inside of the pipes used for the
connections must be well-cleaned before use: wash them with suitable substances and
blow through them with oil or nitrogen. The ends of the tubes must be well debarred and
cleaned. Once the connections are completed, operate the actuator and check that it
functions correctly, that the operation times meet the plant requirements and that there
are no leakages in the hydraulic connections.
