description

The HPR100 hydraulic pump adopts industrial-grade R-series high-speed response energy-storage variable axial plunger structure, comprehensively optimized for the high-frequency cyclic operation and high-efficiency continuous mining characteristics of 90-100 ton large excavators. It breaks through the traditional defect of heavy-duty pumps that prioritize stability at the cost of slow response or pursue speed with insufficient durability, realizing organic integration of rapid follow-up, high energy efficiency and long-cycle stability. The core cylinder block and piston shoe friction pair adopt integral die-forging and low-hysteresis ultra-precision mirror finishing technology, matched with secondary vacuum stress relief treatment, featuring uniform friction clearance, ultra-low response delay and excellent continuous operation wear resistance. It effectively eliminates action stagnation and power discontinuity during frequent switching of rock breaking and earthwork working conditions, greatly improving the overall operation fluency of large-tonnage equipment.

advantages

  • Exclusive R-Series Fast-Response Energy-Storage Architecture, Zero Operation Hysteresis: Different from FA energy-saving balance, SO steady-state low-pulse and V-series extreme impact resistance, HPR100 focuses on high-frequency efficient mining. The exclusive energy-storage closed-loop compensation structure realizes instantaneous pressure and flow follow-up, completely solving the slow response and disjointed compound actions of large-tonnage excavators during frequent working condition switching.
  • Low-Hysteresis Ultra-Precision Friction Pair, Higher Continuous Operation Efficiency: Adopting low-lag mirror finishing and stress relief treatment, the friction pair has ultra-low operating resistance and power loss. It effectively improves the continuous mining efficiency of 90-100 ton equipment in long-shift cyclic operation, bringing stable and efficient production capacity improvement for large mines.
  • High-Speed Anti-Resonance Structure, Stable High-Frequency Switching: Upgraded reinforced swash plate and high-speed stable bearing assembly suppress pump body resonance and vibration during high-frequency variable operation, avoiding pressure floating and jitter caused by frequent load changes, ensuring consistent output in complex alternate mining working conditions.
  • Strict High-Frequency Cycle Testing, Excellent Comprehensive Adaptability: Each HPR100 pump passes high-frequency cycle fatigue test, fast-response precision calibration and long-term high-temperature stability test. It balances response speed, energy efficiency and durability, making it the most cost-effective pump for long-term high-frequency efficient mining of 90-100 ton equipment.

FAQ

  • Q1: What is the core positioning of HPR100 in the full HMG/GM series?
  • A: The HPR100 is thehigh-frequency high-efficiency fast-response flagship model of the HMG/GM series, specially customized for 90-100 ton large mining excavators. It fills the performance gap between steady-state HMSO72 and impact-resistant HMV110, focusing on high-cycle efficient mining scenarios with balanced speed, stability and energy efficiency.
  • Q2: What core faults can HPR100 solve?
  • A: It targets typical faults of 90-100 ton large mining excavators: slow hydraulic power response, obvious compound action hysteresis, pressure floating during high-frequency working condition switching, low continuous operation efficiency, and gradual internal leakage and power attenuation of old pumps.
  • Q3: Is pipeline modification or parameter debugging required after installation?
  • A: No modification and debugging are required. The HPR100 is factory pre-calibrated with large-tonnage high-frequency mining parameters, supporting 1:1 lossless plug-and-play replacement, fully compatible with the original hydraulic system of 90-100 ton large excavators.
  • Q4: What scenarios is HPR100 most suitable for?
  • A: It is exclusively suitable for90-100 ton large open-pit cyclic mining, thick rock layer bulk stripping, high-frequency earth-rock alternate construction and long-shift full-load high-efficiency continuous mining operations.
