Original new excavator DX255LC DX255 K1007950A K9001840 K9001841 doosan swing motor

The excavator swing motor, as the core actuator of hydraulic systems, directly determines equipment performance through its technical specifications. Taking the mainstream swash plate axial piston motor as an example, its operating pressure range typically spans 25-35MPa with displacement specifications covering 80-500cc/r, capable of delivering up to 3000Nm torque. The integrated cross roller bearing design enables axial load capacity exceeding 50kN, while achieving stepless rotation speed regulation from 0-12rpm. Utilizing a 9-piston symmetrical configuration, volumetric efficiency reaches over 97%, complemented by dual-channel flushing valves maintaining oil temperature below 65℃. Latest models incorporate pressure compensators and LUDV control systems, enabling demand-based flow distribution with 18% energy consumption reduction.

In modern construction machinery, swing motors face rigorous reliability challenges across diverse applications. In mining operations requiring 24/7 continuous work under 50℃ temperature fluctuations, motors with special alloy steel housings and nano-coating technology demonstrate exceptional performance. Achieving NAS Class 9 contamination resistance, they integrate emergency manual release mechanisms for safe locking during hydraulic failures. For polar region operations, built-in electric heating modules enable cold starts at -40℃. In port handling scenarios, intelligent motors with digital angle sensors achieve ±0.5° positioning accuracy, coupled with CAN bus interfaces ensuring millisecond-level response synchronization with main control systems.
