Product Description

Hydraulic Pump SWE360 K3V180DT-9N29 Main Pump for EC360 Excavator Construction Machinery Parts

Function

The hydraulic main pump is a key power unit for excavator hydraulic systems. Driven by the engine, it transforms mechanical energy into high-pressure hydraulic energy, and sends pressurized fluid to all executive hydraulic motors to drive boom, arm, bucket, traveling and slewing actions.

Type

Axial variable displacement piston pumps are the mainstream choice for engineering excavators. Mid-to-large size models adopt integrated double main pumps matched with a rear pilot gear pump.
The dual high-pressure pumps have independent oil supply lines, feeding the main control valve to realize compound actions, with working pressure between 28MPa and 35MPa.
The tail-mounted low-pressure pilot pump runs at 3~4MPa with low flow, providing control pressure for operating levers and main valve spools.

Internal Parts

The pump housing and cylinder block are equipped with multiple piston units. These pistons rotate together with the main shaft to complete oil intake and pressure build-up.
Adjusting the swash plate angle changes piston stroke, thereby regulating pump displacement.
The external servo actuator adjusts the swash plate according to hydraulic feedback signals. A bigger angle increases flow and working speed; a smaller angle lowers fuel consumption and avoids engine stall.
The valve plate separates inlet and outlet oil passages to realize oil distribution.

Three Control Modes

Constant power regulation lowers pump displacement when load increases, which safeguards the engine and maximizes power efficiency.
The LS load sensing system delivers flow on demand. Low displacement at idle effectively reduces fuel consumption.
The HP pressure limiting feature minimizes pump displacement at peak system pressure, preventing hydraulic pipes and cylinders from breaking.

Common Failures

Piston wear, valve plate damage or regulator clogging will cause internal leakage, resulting in slow operation and power shortage.
A stuck regulator at full displacement leads to engine overload, black exhaust and stall during heavy-duty work.
Heavy internal leakage generates extra heat from pressure loss and makes hydraulic oil overheat.
Air ingestion, low oil level or defective bearings and pistons will produce abnormal sounds.

Maintenance

Change hydraulic oil and filters on a regular schedule to prevent abrasion of precision parts. Ensure suction pipeline tightness to stop air entry and equipment vibration. Keep hydraulic fluid at the specified level to avoid pump breakdown.
