Product Description
K5V140DTP 9T1L-17T Hydraulic Piston Pump SY235-8 Excavator Main Construction Machinery Parts
Driven directly by the excavator engine, the hydraulic main pump undertakes core energy conversion work to turn mechanical rotational force into high-pressure hydraulic power, supporting all on-site operations including boom lifting, arm stretching, bucket digging, machine traveling and slewing. Almost all engineering excavators adopt axial variable piston pump structure, and medium-to-large construction models are equipped with integrated dual main pumps and rear pilot auxiliary pumps. The main pump delivers stable working pressure of 28 to 35MPa for heavy-duty operations, while the pilot pump outputs 3 to 4MPa low-pressure oil for precise control of operating handles and valve spools. The whole pump assembly relies on matched pistons, cylinder block, adjustable swash plate and hydraulic regulator to flexibly adjust oil displacement, flow volume and fuel consumption according to working conditions. Featuring constant power, load sensing and pressure cutoff functions, it adapts to variable load changes, prevents engine stall and hydraulic system damage, and reduces idle fuel consumption. Common operational defects such as slow movement, insufficient digging force, engine black smoke, overheated hydraulic oil and abnormal pump noise are closely related to internal wear, regulator blockage, pipeline air intake and substandard oil levels, which can be avoided with standardized daily maintenance.
