Product Description

This hydraulic main pump is the core power unit of the hydraulic system for SY195, SY205, SY215, and SY245 excavators. As the hydraulic power heart of the entire machine, it converts the mechanical energy output by the engine into high-pressure hydraulic oil energy, continuously supplying pressure oil flow to the boom, dipper, bucket, slewing motor, and traveling motor. The digging force, the speed of action response, the smoothness of compound actions, and the stability of crushing operations of the entire machine are all directly determined by the hydraulic pump. This series of models are widely used in various working conditions such as earthwork engineering, infrastructure construction, mining stripping, and river channel improvement.

This hydraulic pump adopts a double-axial piston pump integrated structure. The pump housing is made by casting high-strength cast iron as a whole and undergoes aging stress relief treatment, which can withstand long-term alternating high-pressure impacts and effectively reduce the risk of shell deformation and leakage. The core friction pairs such as the cylinder body, piston, flow distributor, and swing assembly are made of high wear-resistant materials. They are precisely forged, heat-treated, strengthened, and mirror-finished processed, with strict control of component clearance gaps, significantly reducing internal volume leakage under high-pressure conditions, maintaining a high volumetric efficiency for a long time, and alleviating the problem of weak thermal machine actions in the later stage of equipment use.

The pump body integrates a complete set of electronic control variable regulation mechanism. It can adjust the output displacement of the two pumps in real time based on the electronic control signal, perfectly matching the SY195, SY205, SY215, and SY245 electric control negative flow control system. It can dynamically match the output flow of the pump according to the load size, achieving a reasonable power matching between the engine and the hydraulic system. Heavy-load digging can output large torque, while light-load operations can automatically reduce power output, balancing the output power and fuel economy. It can adapt to various operation modes such as earthwork, crushing, and heavy-load loading.
