Hydraulic System Main Circuit Extract Outline
• Main pumps (1 and 2) draw hydraulic oil from the hydraulic oil tank. Main pump 1 and main pump 2 deliver pressure oil to the 4-spool control valve and the 5-spool control valve respectively.
• Delivered pressure oil is routed to the motor(s) or cylinder(s) in response to operation(s) of the spool(s) in the control valve(s).
• The return oil from the motor(s) and/or cylinder(s) flows back to the hydraulic oil tank via the control valve and/or the oil cooler.
• When the oil temperature is low (high viscosity), the oil flow resistance increases in the oil cooler, which opens the bypass check valve, allowing hydraulic oil to return directly to the hydraulic oil tank without passing through the oil cooler.
