What is the SHANTUI Duplicate Gear Pump？

  • The Duplicate Gear Pump for the SHANTUI SL60W Wheel Loader is a high-performance hydraulic component engineered to deliver consistent, dual-output pressure for the loader’s critical systems—including lifting, steering, and auxiliary functions. This robust, compact pump integrates two synchronized gear sets within a single housing, ensuring reliable operation under extreme loads and harsh working conditions. Below is a detailed breakdown of its key components and functionality:​
  • 1. Structural Foundation & Housing​
  • Pump Body I & Pump Body II: Two precision-cast iron housings that enclose the dual gear sets. Their internal chambers are machined to tight tolerances to minimize fluid leakage and maximize efficiency. Intermediate (a forged steel spacer) connects the two pump bodies, ensuring alignment and distributing load evenly.​
  • Front Cover & Rear Hood: Forged steel covers that seal the pump’s ends, secured by Socket Cap Screw and Spring Washer to resist vibration-induced loosening. Rectangle Gasket Ring (nitrile rubber) between the covers and pump bodies creates a leakproof seal, while “O” Gasket Ring seals the intermediate joint.​
  • 2. Gear Sets & Power Transmission​
  • Driving Gear Shaft (I/II) & Driven Gear Shaft: High-strength alloy steel shafts with precision-machined gears. The Driving Gear Shafts (powered by the loader’s engine) mesh with Driven Gear Shafts, creating fluid displacement as gears rotate. This dual design allows the pump to deliver two independent pressure outputs—ideal for powering separate hydraulic circuits (e.g., lifting and steering).​
  • Axile Bush & Bearing: Bronze bushings and tapered roller Bearing support the gear shafts, reducing friction and wear. Their self-lubricating design ensures smooth rotation even under high pressure.​
  • 3. Sealing & Contamination Protection​
  • Rotation Axis Lip-type Packing: A lip seal (nitrile rubber) that prevents fluid leakage around the rotating Driving Gear Shafts, with a spring-loaded design to maintain contact under dynamic conditions.​
  • “Ear” Block Slice & “Ear” Airproof: Specialized seals that seal the pump’s mounting “ears” (flanges for attachment to the engine), preventing dust, debris, or moisture from entering critical areas.​
  • Stop Collar: Hardened steel rings that secure bearings and bushings in place, preventing axial movement of shafts during operation.​
  • 4. Pressure Regulation & Safety​
  • Direct-acting Relief Valve: A built-in safety valve that limits system pressure (typically 20–25 MPa) by diverting excess fluid back to the reservoir, protecting hoses, cylinders, and other components from damage.​
  • Side Board: Stamped steel plates that guide fluid flow within each pump body, optimizing suction and discharge efficiency while reducing turbulence.​
  • 5. Assembly & Identification​
  • Scutcheon & Rivet: A metal nameplate (secured by Rivet) that displays technical specifications (flow rate, pressure rating) for easy maintenance and replacement.​
  • Axile Bush: Bronze bushings that provide additional support to gear shafts in high-stress areas, extending service life.​
  • System Functionality​
  • The Duplicate Gear Pump operates by converting rotational engine power into hydraulic pressure. As Driving Gear Shafts (I/II) rotate, they drive Driven Gear Shafts, creating vacuum in the suction side to draw fluid from the reservoir. Fluid is then pressurized in the discharge side, with dual outputs feeding separate hydraulic circuits. Seals and Gaskets prevent leakage, while Bearings and Axile Bush ensure low-friction operation. The Direct-acting Relief Valve safeguards against overpressure, making this pump a reliable heart of the SL60W’s hydraulic system—critical for maximizing productivity in construction, mining, and material handling.
