Product Description

Kobelco SK200-6E K3V112DTP-9TEL Main Hydraulic Pump LQ10V00006F1 Excavator Parts

Function

Acting as the prime power core for an excavator hydraulic circuit, the main hydraulic pump receives driving torque from the engine. It transforms mechanical power into high-pressure hydraulic power, conveying pressurized oil to travel, swing, boom, arm and bucket hydraulic motors to actuate all machine movements.

Type

Axial variable displacement piston pumps serve as the standard configuration for construction excavators. Mid and large-tonnage machines employ combined twin main pumps fitted with a rear-mounted pilot gear pump.
The two high-pressure pumps feature separate oil supply circuits, supplying oil to different ports of the main control valve for compound movement execution, with working pressure ranging 28–35MPa.
Positioned at the pump rear, the low-pressure pilot pump runs at 3–4MPa with modest flow, delivering pilot pressure oil for control levers and main valve spool actuation.

Internal Parts

Within the pump casing and cylinder block, multiple piston assemblies spin synchronously with the main shaft to finish oil intake and pressure buildup.
Altering the swash plate inclination angle modifies piston stroke, thereby adjusting the pump’s volumetric displacement.
An external servo actuator modulates swash plate position responding to hydraulic feedback signals. A steeper angle boosts displacement and flow for faster work cycles; a shallower angle curbs fuel consumption and eliminates engine stall risks.
The valve plate segregates low-pressure intake and high-pressure discharge ports to realize orderly oil distribution.

Three Control Modes

Constant power control automatically decreases pump displacement amid rising loads, safeguarding the engine from stalling while maximizing power utilization efficiency.
The LS load-sensing system supplies hydraulic flow matching actual demand, maintaining low displacement during idling to cut fuel expenditure.
The HP pressure limit function scales down pump displacement once system pressure hits its upper threshold, shielding hydraulic hoses and cylinders from burst damage.

Common Failures

Piston or valve plate wear, alongside regulator clogging, triggers internal leakage, resulting in sluggish operation and inadequate power output.
A regulator seized at maximum displacement induces engine overloading, black exhaust emission and stalling under heavy-duty conditions.
Severe internal leakage converts pressure losses into heat, triggering abnormal hydraulic oil overheating.
Oil aeration, insufficient hydraulic fluid level, or damaged bearings and pistons generate abnormal operational noise.

Maintenance

Conduct periodic replacement of hydraulic oil and filter cartridges to prevent abrasive wear on precision internal components. Guarantee full tightness of suction lines to prevent air ingestion and mechanical vibration. Keep hydraulic fluid at prescribed level to avoid premature pump breakdown.
