Product details
YEOSHE V38 A4R10X Hydraulic Piston Pump
I. Technical Parameters and Core Features
•Model Positioning: Part of Taiwan YEOSHE's V-series axial piston pump family, featuring a swashplate variable design that enables flow control via swashplate angle adjustment.
•Key Parameters:
• Displacement: 37.8 cm³/rev (may vary slightly by model variant).
• Pressure Range: Continuous operating pressure of 175 kgf/cm² (approx. 17.5 MPa), with peak pressure up to 250 kgf/cm² (approx. 25 MPa).
• Rotational Speed: Maximum 1800 RPM, minimum 500 RPM, suitable for medium-to-high speed applications.
• Weight: Approximately 26kg, designed with compact size and lightweight characteristics for direct motor coupling.
• Control Modes: Supports multiple control types (e.g., Type A/B/C), integrating pressure, flow, and power control functions to meet energy-saving and miniaturization requirements.•Materials and Design: Utilizes specialized alloy materials for low-noise operation, long lifespan, and high efficiency. Adjustable swashplate angle optimizes oil suction performance, reduces oil temperature rise, and allows for smaller oil tank configurations.
II. Performance Advantages and Application Scenarios
•Low-Noise Operation: Maintains low noise levels across the entire pressure range through optimized fluid dynamics design and precision manufacturing.
•Energy Efficiency & High Performance: Minimal power loss and reduced oil temperature rise, compatible with energy-saving hydraulic systems. High volumetric efficiency with minimal leakage, suitable for high-pressure, high-power applications.
•Application Fields:
• Industrial Equipment: Machine tools, forging presses, plastic molding machines, injection molding machines, etc.
• Construction Machinery: Concrete mixer trucks, road construction equipment, cranes, excavators, etc.
• Specialized Industries: Marine, aviation, metallurgy, tire forming machines, and specialized machinery.
III. Maintenance and Troubleshooting Guidelines
•Routine Maintenance:
• Oil Management: Regularly check oil level and quality (color, contaminants, moisture); recommend using L-HM32/46 anti-wear hydraulic oil (avoid oil temperature exceeding 65°C).
• Operational Monitoring: Monitor pressure, flow, temperature, noise, and leakage; investigate abnormal noise, vibration, or pressure fluctuations immediately.
• Scheduled Maintenance: Replace hydraulic oil and filters every 500-1000 operating hours; inspect seals, shaft seals, and pipe connections to prevent leaks.•Common Troubleshooting:
• Neutral Position Deviation: Adjust controller or replace worn components (e.g., swashplate, pistons).
• Flow Fluctuation: Check control piston, spring stiffness, and damper effectiveness in the variable mechanism; clear debris or replace damaged parts.
• Pressure Anomalies: Investigate air leaks in suction lines, relief valve malfunctions, or cylinder/port plate wear; perform grinding or component replacement as needed.
• Vibration and Noise: Verify coupling alignment, bearing condition, piping stability, and oil cleanliness to prevent cavitation or resonance.
IV. Industry Certification and Reliability
•Quality Assurance: As a renowned hydraulic brand, YEOSHE products undergo rigorous testing and comply with international standards (e.g., ISO, DIN), with global market applications.
•Durability: Specialized alloy materials and precision machining ensure high wear resistance and extended service life; modular design facilitates maintenance and upgrades.
