Due to its large displacement, high pressure resistance, and energy-saving control, it is widely used in heavy-duty hydraulic systems, including: 1) Construction machinery (large excavators, bulldozers, road rollers); 2) Mining equipment (mine loaders, hydraulic supports); 3) Industrial machinery (steel mill rolling equipment, forging presses); 4) Marine equipment (ship deck cranes, steering systems); 5) Agricultural machinery (large harvesters, irrigation machines); 6) Municipal engineering equipment (sewage treatment presses, garbage compactors).

Recommended hydraulic oil types: 1) Mineral oil-based anti-wear hydraulic oil (ISO VG 32, 46, 68 are preferred); 2) Synthetic hydraulic oil (esters, polyglycols) for extreme temperature environments (-20℃ below or 60℃ above); 3) Biodegradable hydraulic oil for environmentally sensitive areas (e.g., riverside construction). Oil quality requirements: 1) Cleanliness: NAS 8 class or higher (ISO 16/13); 2) Water content: ≤0.1%; 3) Acid value: ≤0.5 mg KOH/g; 4) No free impurities or sediment.
