description

The K3VL45 pump adopts Kawasaki classic K3VL series high-displacement mining-grade variable piston pump structure, professionally upgraded for the extreme heat dissipation demand of 70–80 ton super-large mining excavators. Compared with small-displacement fan pumps, the K3VL45 features larger theoretical displacement, stronger overload resistance and more accurate load adaptive variable regulation, fully matching the high-power heat dissipation demand of SANY SY750 heavy-duty mining equipment. Equipped with high-strength hardened piston cylinder assembly, wear-resistant copper valve plate flow distribution structure, fatigue-resistant integral swash plate mechanism and imported high-temperature anti-aging composite sealing system. The internal matching clearance is precisely controlled with ultra-low internal leakage, maintaining stable pressure and flow output without attenuation under long-term high-temperature and high-pressure cyclic working conditions.

advantages

  • Genuine Kawasaki K3VL45 original pump, professionally calibrated for SANY SY750 super-large mining excavator hydraulic heat dissipation system, perfectly matching original hydraulic parameters and temperature control logic without power mismatch or insufficient cooling capacity.
  • Large-displacement mining-grade variable structure, with higher flow output and overload resistance than small-displacement fan pumps, completely solving the industry problem of high-temperature alarm and weak heat dissipation of 75-ton heavy-duty mining machines under extreme full-load mining conditions.
  • High-precision internal matching components minimize internal leakage and pressure fluctuation, ensuring synchronous and stable speed regulation of the supporting fan motor, no jitter, stalling or speed drop during long-term ultra-high-intensity mining operation.
  • Imported high-temperature anti-aging composite sealing system maintains stable sealing performance under long-term high-heat and high-pressure impact, effectively preventing oil leakage and performance attenuation, adapting to all-weather continuous heavy-duty operation of 75-ton super-large equipment.
  • Reinforced high-rigidity cast pump body has excellent anti-vibration, anti-impact and anti-dust erosion capabilities, maintaining stable working performance in harsh mine environments with ultra-low failure rate and long service life.
  • Intelligent load adaptive variable control technology realizes on-demand oil supply, automatically adjusting flow and pressure according to equipment load and temperature, reducing idle power loss and significantly improving equipment fuel economy.

FAQ

  • Q1: How to prevent oil leakage of the K3VL45 fan pump? A: Regularly check the mounting bolts, high-pressure inlet and outlet joints and sealing surfaces of the K3VL45 fan pump. Fasten loose bolts and replace aging seals in time to eliminate oil leakage risks caused by long-term ultra-heavy-load vibration and strong mechanical impact in mining working conditions.
  • Q2: Why is regular cleaning of radiator and fan blade essential? A: Accumulated thick mine dust, sediment and dirt will block heat dissipation channels, causing long-term overload operation of the variable pump and accelerating wear of internal precision components. Regular cleaning ensures unobstructed heat dissipation and stable pump operation under heavy mining loads.
  • Q3: What are the standards for hydraulic oil and filter replacement? A: Replace high-pressure hydraulic oil and special precision filter elements strictly in accordance with SANY official mining equipment maintenance cycle. It effectively prevents hard mine impurities from scratching precision matching pairs and ensures stable variable pressure and large-flow output of the K3VL45 pump body.
  • Q4: What daily inspection work is required for the fan pump? A: Periodically detect the working pressure, variable response sensitivity and flow stability of the pump body to ensure stable operation within the rated range and meet the extreme full-load heat dissipation requirements of SANY SY750 75-ton super-large mining excavators.
  • Q5: How to extend the service life of Kawasaki K3VL45 fan pump? A: Avoid long-term extreme high-temperature overload operation and abnormal hydraulic pressure impact, which can effectively reduce fatigue wear of internal variable mechanism and precision components and greatly extend the service life of mining-grade heavy-duty fan pumps.
  • Q6: When does the K3VL45 fan pump need to be replaced? A: When typical faults occur including weak heat dissipation, unstable fan speed, pump body oil leakage and continuous system high temperature alarm, the genuine K3VL45 fan pump needs to be replaced in time to restore the extreme heavy-duty cooling performance of SANY SY750 mining equipment.
