COMPONENT OPERATION / Pump Device
OUTLINE
The pump device consists of transmission (9), main pump (pump 1 (1), pump 2 (2)), pilot pump (5) and steering pump (6).
The engine output is transmitted to transmission (9) via coupling (13). After being distributed by the gear, the engine power drives pump 1 (1), 2 (2), pilot pump (5) and steering pump (6). The reduction gear ratios of the main pump, pilot pump (5) and steering pump
(6) are 1:1. Transmission (9) is lubricated with engine oil.
The main pump is a bent-axis type variable displacement axial plunger pump. Pump 1 (1) and pump 2 (2) are integrated as two units in one housing.
Pilot pump (5) and steering pump (6) are gear pumps. Pump delivery pressure sensors (3, 4) and pump control pressure sensors (7, 8) are installed in order to control the pump and valve. (Refer to the SYSTEM / Control System group.)
