Applications:
1. This axial piston pump delivers 280bar continuous pressure for blast furnace cooling systems in metallurgy. Its pressure-compensated flow control ensures stable molten metal pouring operations, while ISO 4406 contamination resistance guarantees reliability under extreme heat.
2. The DFR dual-mode control in this hydraulic pump enables precise synchronization between crystallizer vibration frequency and steel flow rate. With <100ms response time and 18-140cc displacement range, it efficiently adapts to various continuous casting requirements.
3. This axial piston pump provides 350bar peak pressure for hydraulic rock drills in open-pit mining. The load-sensing system auto-adjusts flow according to drilling resistance, while dual drain ports maintain 95%+ volumetric efficiency in dusty conditions.
4. The FR flow control mode in this piston pump enables stepless speed adjustment (0-140cc/min) for underground conveyor systems. Cast steel housing provides superior corrosion resistance in humid mine environments, extending service intervals.
Competitive Advantage:
1. This axial piston pump delivers 280bar continuous pressure and 350bar peak performance for metallurgical systems. Cast steel housing withstands extreme mechanical stress with 10,000+ hours B10 lifespan.
2. Flow rate proportionally adjusts with drive speed and displacement via stepless swashplate control (0-100%), achieving <100ms response for injection molding clamping precision.
3. Dual drain ports with ISO 4406 20/18/15 contamination resistance maintain >95% volumetric efficiency for mining machinery in dusty environments.
4. DFR/DFR1 dual-mode control intelligently switches between 280bar injection and 50bar filling modes for die casting, reducing energy consumption by 30%.
The Analysis For Rexroth A10V(S)O Axial Piston Pump Common Breakdown:
1. Insufficient Flow Output: Blocked suction lines or clogged filters (oil viscosity >1000cSt) increase resistance. Clean filters and monitor oil temperature. Adjust variable piston to increase swashplate angle from <5° to 18° for flow restoration.
2. Non-zero Flow at Neutral: Control rod misalignment causes swashplate deviation. Recalibrate zero point. Replace bronze bushings if wear exceeds 0.1mm, apply molybdenum disulfide grease.
3. Pressure Fluctuation: Foreign particles (>25μm) in variable mechanism require disassembly cleaning with 10μm filter. Replace DIN 2098 springs if stiffness degrades over 15%.
4. Overheating: Adjust piston-cylinder clearance to 15-20μm if >50μm. Clean cooler fins or install water cooling when oil temperature exceeds 80°C.
