Product Description

K3V112DTP-0E11 Hydraulic Axial Piston Pump Assembly for SY195 SY215 Excavator Spare Parts

Function

The hydraulic main pump is a vital power component of excavator hydraulic circuits. Driven by the engine, it achieves the conversion from mechanical energy to high-pressure hydraulic energy, and delivers pressurized fluid to hydraulic motors to drive all operational movements.

Type

Axial variable displacement piston pumps are the mainstream choice for engineering excavators. Medium and large tonnage excavators adopt integrated dual main pumps equipped with a rear pilot gear pump.
The dual high-pressure pumps adopt two independent oil supply passages, feeding oil to the main control valve to realize composite actions, with working pressure 28~35MPa.
The low-pressure pilot pump mounted on the pump tail runs at 3~4MPa with low flow rate, providing pilot oil for operating levers and main valve spools.

Internal Parts

The housing and cylinder block are fitted with multiple piston assemblies, which rotate with the main shaft to complete oil suction and pressure build-up.
The swash plate changes its tilt angle to adjust piston stroke and pump volumetric displacement.
The external servo regulator drives the swash plate according to hydraulic feedback. Increased angle raises displacement and flow; reduced angle lowers fuel consumption and prevents engine stall.
The valve plate separates low-pressure inlet and high-pressure outlet to complete fluid distribution.

Three Control Modes

Constant power regulation automatically reduces pump displacement under rising load to protect the engine and fully utilize power.
The LS load sensing system supplies flow on demand and maintains low displacement at idle to save fuel.
The HP pressure limiting function minimizes pump displacement at peak pressure to protect hydraulic pipelines and cylinders from damage.

Common Failures

Internal leakage resulting from worn pistons, damaged valve plates or regulator blockage leads to slow operation and insufficient power.
Regulator locked at maximum displacement will cause engine overload, black smoke and stall under heavy load.
Excessive internal leakage converts pressure loss into thermal energy and causes hydraulic oil temperature to rise abnormally. Air entrainment, insufficient oil or damaged bearings and pistons will produce abnormal noise.

Maintenance

Replace hydraulic oil and filter elements periodically to prevent abrasive damage to precision parts. Ensure suction pipelines are well sealed to avoid air intake and vibration. Keep hydraulic fluid at standard level to avoid pump failure.
