II. Key Specifications
1. Operating Principle
• Utilizes anaxial conical piston rotor setwith a swashplate design, where pistons reciprocate within cylinders to achieve suction and discharge of hydraulic fluid, converting hydraulic energy into mechanical energy (as a motor) or vice versa (as a pump).
2. Core Parameters
• Displacement: 55 cm³/rev (may vary slightly based on model suffix).
• Nominal Pressure: 32 MPa, suitable for high-pressure applications.
• Operating Temperature Range: 30°C to 90°C, adaptable to harsh environments.
• Fluid Compatibility: Hydraulic oil (cleanliness required to prevent wear).
• Mounting Type: Flange-mounted for easy integration with gearboxes or other equipment.
• Material: Cast iron housing for durability.
3. Structural Features
• Swashplate Design:
• Piston rotor set angled relative to the drive shaft, with a spherical valve plate enabling automatic centering to reduce leakage and wear.
• Compact & High Power Density:
• Space-saving design ideal for applications with limited installation space.
• Long-Life Bearing System:
• Robust bearings designed for high loads and continuous operation.
• Low Noise Operation:
• Optimized fluid channels and valve plate structure minimize operational noise.
------
III. Functions & Applications
1. As a Hydraulic Pump
• Converts mechanical energy (e.g., from an electric motor or engine) into hydraulic energy in open or closed-loop systems, supplying power to actuators (e.g., hydraulic cylinders, motors).
• Ideal for high-pressure, low-flow applications such as:
• Travel drives and slewing mechanisms in construction machinery.
2. As a Hydraulic Motor
• Converts hydraulic energy into mechanical energy in hydrostatic transmission systems, driving rotational loads.
• Output Speed: Proportional to pump flow and motor displacement.
• Output Torque: Proportional to pressure differential and displacement.
• Suitable for precision-controlled speed and torque applications, such as:
• Winches and conveyors in mining equipment.
3. Typical Applications
• Construction Machinery:
• Excavators, loaders, road rollers, cranes (travel, slewing, and hoisting systems).
• Mining Equipment:
• Roadheaders, shearers, hoists (drive systems).
• Metallurgical Machinery:
• Rolling mills, continuous casting machines (hydraulic drives).
• Agricultural Machinery:
• Large tractors, combine harvesters (hydraulic systems).

IV. Technical Advantages
1. High Efficiency & Energy Savings
• Reduced internal leakage due to swashplate design improves volumetric efficiency.
• Optimized fluid channels minimize pressure losses and energy consumption.
2. Reliability & Durability
• Robust cast iron housing and long-life bearings withstand harsh operating conditions.
• Spherical valve plate with automatic centering reduces wear and extends service life.
3. Easy Maintenance
• Modular design simplifies disassembly and repair.
• Standardized interfaces and mounting dimensions facilitate replacement and upgrades.
4. Flexible Control
• Compatible with various control valves (e.g., proportional, servo) for precise speed and torque control.
• Supports both open- and closed-loop circuit designs.
------
V. Selection & Usage Considerations
1. Selection Criteria
• System Pressure: Ensure nominal pressure exceeds maximum system operating pressure.
• Flow Requirements: Match displacement to actuator flow demands.
• Installation Space: Choose flange mounting or other configurations based on equipment layout.
• Environmental Conditions: Consider temperature, humidity, and dust levels.
2. Usage & Maintenance Tips
• Fluid Cleanliness:
• Regularly replace hydraulic oil and maintain cleanliness to prevent contamination-induced wear.
• Temperature Monitoring:
• Avoid operation outside specified temperature ranges to prevent performance degradation.
• Abnormal Noise/Vibration:
• Immediately shut down and inspect if unusual sounds or vibrations occur.
• Scheduled Maintenance:
• Replace seals, bearings, and other wear parts per manufacturer recommendations.
