•
Filtration
: class 21/19/16 contamination according to ISO 4406 to
be obtained with a ßx = 75 filter.
•
Check circuit connections
: they must be applied in the same
rotation direction as that indicated by the arrow on the pump front
flange.
•
Draining
: connect directly to the tank above the maximum oil
level. Operating without draining line may damage the motor.
Pic. 4.6
•
Distributor
: open-centre distributor in central idle position
(vacuum pump off). It must be equipped with an adjustable
overpressure safety valve.
•
Motor pipeline
: outlet pipe must not be of a smaller diameter than
that of the inlet port. Inlet pipes always have a diameter smaller than
outlet pipes. Choose preferably flexible pipes to avoid vibration
transmission.
• Tank
: with suction pipe and return separated by baffles. If
necessary, use a heat exchanger to avoid oil heating above 70-80°C
and protect it from extreme pressure with a pressure relief valve.
Minimum approximate capacity: as twice as the circulation flow.
•
Starting-up
: be sure that the system is well cleaned and pour oil
into the tank and into the motor housing (necessary to lubricate the
internal bearings).
• Vent the circuit and adjust the overpressure safety valve to the
lowest possible value.
• Check the oil tank level.
• Increase pressure and rotation speed until operating values are
reached.
