PUMPS AND HYDRAULIC LINES SYSTEM
The machine hydraulic system is powered by n.3 pumps units:
1.
Pumps unit connected to the engine, n.2 pumps 3,15cc/rev each
2.
Pumps unit connected to the electric motor, n.2 pumps 3,15 cc/rev
3.
Emergency hand pump, this has only one outlet line but it’s equipped with
a deviator to select which one of the two lines should be fed
NOTE: Lithium machine is equipped with only one pumps unit, with n.2 pumps
3,15 cc/rev, connected to the three-phases electric motor, plus the hand pump.
All of the pumps units outlines are conveyed through the hydraulic manifold
into two lines A and B. Six one-way valves avoid oil under pressure to flow back
to the tank through an unused pump unit.
The position of the pumps arrivals to the hydraulic manifold is described here
below.
Every time that hydraulic oil tank is opened (depressurized), such as in case
of hydraulic oil filter replacement, it must be pressurized again (with cork
screwed) at minimum rpm, to avoid cavitation.
