GEAR PUMP
The gear pump (1) is a constant-volume pump with dou-
ble-gear pumps (P3, P4) that discharges a constant vol-
ume of discharge material over a constant speed.
The pump P3 is used for the 2nd and 3rd auxiliary line
piping, blade, and slew motor, and the pump P4 is used
to discharge the pilot pressure oil.
The gear pump (1) is connected by the hydraulic pump
(piston) (2) and coupling (3), and the hydraulic pump (2)
is connected by the engine (4) and coupling (5), with the
drive gear (6) of the gear pump (1) being rotated with the
rotation of the engine.
The gear pump is located inside one of the gear cases
and is interlocked with the drive gear (6) and driven gear
(7). When the drive gear (6) is rotated, the space be-
tween the case and the gears is filled with that oil flowing
from the inlet to the outlet.
