Engineering Specifications of Hengli Heavy Excavator Hydraulic Cylinders

Hengli boom, stick, and bucket hydraulic cylinders are engineered for mobile construction excavators ranging from 10 to 700 metric tons as well as tunnel boring machine thrust systems.

Fabricated from alloy structural steel forgings with precision honed seamless barrel tubes, the cylinders feature induction hardened piston rods finished with multilayer nickel-chrome plating for severe corrosion resistance.

Integrated cushion valves softly decelerate heavy attachment linkages at stroke extremities, preventing destructive pressure spikes across the hydraulic circuit at operating pressures up to 35 MPa.

Operating Characteristics of Hengli HP3V and HP6V Axial Piston Pumps

Hengli variable displacement axial piston pumps series HP3V and HP6V utilize swashplate rotary architecture configured for high pressure open hydraulic circuits.

Delivering continuous operating pressure of 350 bar and peak tolerance up to 400 bar with displacements from 18 to 140 cc/rev, the pumps deliver exceptional power density.

Integrated control heads feature load sensing flow regulation, remote pressure cut-off, and electronic proportional displacement limiting, dynamically matching pump delivery to prime mover diesel torque curves.

Load Sensing Proportional Flow Control in Hengli HVSP Sectional Valves

Hengli HVSP series sectional directional control valves incorporate individual post-compensated pressure regulators across each working slice for mobile excavators and crawler cranes.

The post-compensation load sensing circuitry delivers proportional flow sharing independent of varying load pressures when multiple actuators operate simultaneously.

High tensile iron casting sections withstand continuous system pressures up to 420 bar while accommodating maximum flow rates reaching 400 liters per minute.
