description

The K3V180 hydraulic pump adopts an ultra-heavy integrated swash plate variable structure, with core friction pairs such as plunger, cylinder block and valve plate processed by ultra-precision mirror grinding technology. The internal matching clearance is strictly controlled within micron-level tolerances, ensuring ultra-low friction loss and extreme wear resistance during long-term ultra-high load operation. The internal flow channel adopts optimized fluid dynamic design, which minimizes hydraulic oil circulation resistance and energy loss, effectively restraining heat accumulation during continuous heavy-load operation and greatly improving hydraulic response sensitivity and compound action coordination. The pump body is integrally cast with high-strength forged ductile iron, featuring ultra-high compression resistance, impact resistance and vibration resistance, adapting to extreme harsh environments such as quarry strong impact load, long-term mud-water erosion, high-frequency vibration and alternating extreme loads.

advantages

  • 180ml/r Super Large Displacement, Extreme Power Reserve: Featuring industry-leading 180ml/r large displacement, the K3V180 main pump provides ultra-large hydraulic flow and super-high pressure output. It completely solves the power shortage and weak rock breaking problems of K3V112 and K3V140 pumps when facing hard rock and ultra-deep excavation, and maintains strong and steady power output for full-load extreme operations of 40-ton class super-large excavators.
  • Ultra-Precision Variable Control, Smooth Extreme Compound Action: Adopting upgraded heavy-duty variable algorithm, the pump can intelligently adjust flow and pressure according to extreme load changes. The switching between no-load, light-load and extreme heavy-load is smooth without stuttering, effectively improving the problems of slow response, jitter and uncoordinated linkage of super-large excavators after long-term aging.
  • Professional Heavy-Duty Heat Dissipation, Non-Stop Operation: The enlarged and optimized internal flow channel reduces hydraulic heat accumulation and flow resistance. Even after 24-hour uninterrupted full-load mining and rock breaking operations, the oil temperature rises slowly, avoiding equipment shutdown and efficiency reduction caused by hydraulic overheating protection.
  • Ultra-Hard Alloy Core, Permanent Pressure Holding Stability: The core friction pairs are made of custom ultra-hard wear-resistant alloy with mirror grinding process, achieving extremely low internal wear rate. It fundamentally avoids system pressure drop, internal leakage and hydraulic drifting under long-term cyclic extreme load, keeping the whole hydraulic system in optimal working condition.
  • Standard Plug-and-Play Installation, Low Lifecycle Cost: Fully consistent with the original installation hole positions and high-pressure pipeline interfaces of 38–50 ton super-large excavators, supporting direct replacement without secondary processing. It shortens maintenance cycle, reduces expensive downtime loss of heavy equipment, and lowers long-term hydraulic system failure rate and operation cost.

FAQ

  • Q1: What tonnage of excavators does the K3V180 hydraulic pump apply to?
  • A: The K3V180 hydraulic main pump is a super-large displacement heavy-duty pump exclusively designed for 38–50 ton super-large excavators, widely used in high-intensity mining and super-large earthwork projects, compatible with most mainstream 40-ton class heavy machinery.
  • Q2: What symptoms indicate that the K3V180 main pump needs to be replaced?
  • A: If the excavator has weak rock breaking force, slow full-machine compound actions, insufficient traveling power under heavy load, frequent pressure drop, abnormally high hydraulic oil temperature and jittery linkage during mining operations, the original main pump is severely worn and fails to hold pressure, requiring timely replacement.
  • Q3: Is equipment modification required for K3V180 pump replacement?
  • A: No modification is needed. The K3V180 pump is manufactured strictly according to original factory standards with fully consistent hole positions and high-pressure interfaces, supporting direct plug-and-play installation for rapid on-site maintenance.
  • Q4: What is the difference between K3V180 and K3V140 pumps?
  • A: The K3V180 has larger displacement, higher pressure grade and stronger extreme load resistance, suitable for 38–50 ton super-large excavators and mining extreme working conditions. The K3V140 is only applicable to 30–36 ton heavy excavators, with insufficient power reserve for ultra-heavy rock breaking operations.
  • Q5: How to maintain the K3V180 main pump to extend its service life?
  • A: Regularly replace genuine high-grade hydraulic oil and filter elements to ensure clean oil circulation. Avoid long-term extreme overload operation. Regularly check high-pressure pipeline leakage and blockage. Standard daily maintenance can effectively delay core wear and main pump aging.
