description

The GM38VB hydraulic pump adopts industrial top-level VB series super-heavy-duty anti-shock variable axial plunger structure, upgraded and optimized on the basis of VA/VL large-tonnage pump series. It has stronger impact resistance, higher structural rigidity and better long-cycle fatigue resistance, fully adapting to the extreme working characteristics of frequent hard rock impact and continuous full-load operation of 36-40 ton super-large excavators. The core cylinder block and piston shoe friction pair are processed by integral high-pressure die forging and ultra-precision mirror grinding, matched with secondary vacuum quenching and hardening process, with extreme wear resistance and anti-impact toughness, effectively restraining internal leakage and pressure fluctuation caused by long-term high-frequency rock impact and harsh mine environment.

advantages

  • Secondary Hardened Mirror Friction Pair, Super Anti-Impact & Wear-Resistant: The die-forged cylinder block and ultra-wear-resistant alloy piston shoe are processed by mirror grinding and secondary vacuum quenching, with far stronger impact toughness than ordinary pump bodies. It inhibits internal leakage growth caused by long-term frequent rock impact and maintains stable pressure and flow output throughout the service cycle.
  • High-Temperature Anti-Fatigue Design, Adapt to Round-The-Clock Mining: Optimized high-temperature resistant sealing system and anti-fatigue structural layout solve the problems of easy aging, oil leakage and fatigue failure of old pumps under long-term high-temperature and high-load mining conditions, realizing long-term stable operation without attenuation.
  • Double-Reinforced Integral Structure, Vibration & Noise Reduction: The thickened double-reinforced swash plate and customized shock-absorbing heavy-duty bearing assembly resist extreme impact load and long-cycle operation fatigue, reduce pump body resonance and abnormal noise, and greatly improve the overall stability of super-large equipment.
  • 1:1 Lossless Plug-and-Play Replacement, Save Maintenance Cost: Standard large-size flange and oil port position, no pipeline modification or parameter debugging required for replacement. It is perfectly compatible with the original hydraulic system of 36-40 ton super-large excavators, reducing maintenance difficulty and equipment downtime loss.
  • Strict Extreme Condition Testing, Reliable Extreme Working Condition Performance: Each GM38VB pump passes impact resistance test, high-temperature long-cycle fatigue aging, full-range variable precision calibration and extreme load simulation, ensuring stable and reliable performance for all-weather ultra-heavy-duty mining working conditions.

FAQ

  • Q1: What are the differences between GM38VB, GM35VA and GM35VL?
  • A: GM35VL focuses on ultra-large flow and heavy stripping, GM35VA focuses on precise voltage stabilization and low fluctuation; the newly upgraded GM38VB focuses on extreme impact resistance and anti-fatigue durability, with higher pressure grade, stronger impact compensation ability, and is specially designed for 36-40 ton super-large excavator high-frequency rock breaking and round-the-clock mining extreme working conditions.
  • Q2: What core faults can GM38VB effectively solve?
  • A: It targets and solves typical stubborn faults of 36-40 ton super-large mining excavators: rock-breaking impact jitter, load pressure drift, delayed variable response, severe high-temperature power attenuation, short service life of old pumps and persistent oil seepage and leakage.
  • Q3: Is on-site modification or parameter debugging required for installation?
  • A: No modification and debugging are required. Standard universal large flange interface supports 1:1 plug-and-play direct replacement, fully matching the original hydraulic parameters and assembly standards of 36-40 ton super-large excavators.
  • Q4: What working conditions is GM38VB most suitable for?
  • A: It is specially customized for super-large open-pit mines, high-frequency hard rock breaking, large-scale mountain stripping, and long-term uninterrupted full-load operation, and is the preferred upgrade model for extreme impact heavy-load working conditions.
  • Q5: What are the key maintenance points for GM38VB?
  • A: Keep the hydraulic oil clean and replace filter elements regularly to avoid impurity abrasion of the friction pair; avoid long-term extreme overload impact operation; regularly check the pump body pressure and sealing status, and control hydraulic oil temperature during continuous high-temperature operation to extend the anti-fatigue service life.
