description

The HMGF68FA hydraulic pump adopts industrial top-grade FA-series full-domain adaptive high-power variable axial plunger structure, comprehensively upgraded and optimized for the ultra-heavy load characteristics of 65-70 ton super-large mining excavators. It perfectly balances ultra-high pressure, super-large flow and low energy consumption, solving the single-performance defect of traditional heavy-duty pumps that either sacrifice energy efficiency for high power or lack stability under extreme load. The core cylinder block and piston shoe friction pair adopt one-piece die-forging forming and ultra-precision mirror finishing technology, matched with secondary high-temperature vacuum quenching and stress relief treatment, with ultra-high structural rigidity, wear resistance and impact toughness. It effectively inhibits internal leakage growth and power attenuation caused by long-term ultra-heavy load impact and high-temperature mining operation.

advantages

  • Exclusive FA Full-Domain Adaptive Technology, Perfect Ultra-Heavy Load Matching: Different from VA stable voltage, VL large flow and VB anti-shock single-oriented pumps, HMGF68FA adopts upgraded FA full-domain intelligent adaptive algorithm. It automatically balances pressure and flow according to ultra-heavy stripping and hard rock breaking loads, solves power mismatch and energy waste of traditional super-large pumps, and realizes high-efficiency and stable operation in full working conditions.
  • Secondary Hardened Ultra-Low-Loss Friction Pair, Higher Energy-Saving Efficiency: The die-forged high-strength cylinder block and low-friction super wear-resistant piston shoe are processed by mirror finishing and secondary vacuum quenching, with extremely low internal friction loss. It effectively reduces full-load invalid power consumption of 65-70 ton super-large excavators, bringing significant long-term energy-saving benefits for round-the-clock mining operations.
  • Flexible Anti-Fatigue Variable Structure, No Jitter Under Extreme Impact: Upgraded high-power flexible swash plate and closed-loop real-time compensation system realize instantaneous pressure and flow compensation under ultra-heavy impact load. It completely solves the core pain points of whole machine jitter and power sudden drop during hard rock breaking of old super-large mining excavators.
  • Extreme Weather Resistant Sealing, Long-Term High-Temperature Stable Operation: Equipped with upgraded multi-layer composite ultra-high-pressure and high-temperature resistant sealing kits, it resists long-term high-temperature aging and hydraulic oil scouring in mine environments, avoiding leakage and performance attenuation of ordinary heavy-duty pumps after long-cycle operation.

FAQ

  • Q1: What is the core positioning of HMGF68FA in the full series?
  • A: The HMGF68FA is the top ultra-large-tonnage energy-saving adaptive heavy-duty model of the HMG/GM full series. It is upgraded based on the FA balanced energy-saving system, retaining efficient energy-saving advantages while adding ultra-heavy-load impact resistance and full-domain load adaptation capabilities, specially customized for 65-70 ton extreme mining super-large excavators.
  • Q2: What core problems can HMGF68FA solve?
  • A: It targets typical faults of 65-70 ton super-large mining excavators: severe full-load fuel consumption, power attenuation under long-term high temperature, jitter during ultra-heavy rock breaking, mismatched flow-pressure load, excessive internal leakage and persistent oil seepage of old pumps.
  • Q3: Is on-site modification or parameter adjustment required during installation?
  • A: No modification and debugging are required. The HMGF68FA adopts factory pre-calibrated ultra-heavy-load parameter logic, supporting 1:1 lossless plug-and-play replacement, fully compatible with the original hydraulic system of 65-70 ton super-large excavators.
  • Q4: What scenarios is HMGF68FA most suitable for?
  • A: It is exclusively suitable for super-large open-pit mines, ultra-heavy hard rock breaking, massive mountain stripping, and long-term round-the-clock full-load mining operation, and is the preferred upgrade model for extreme ultra-heavy-duty mining working conditions.
