Product Description

Excavator pilot pump  A8VO160 for CAT 330B excavator

Product Description 

The A8VO160 is a Rexroth bevel-axis axial piston variable displacement dual pump, part of the A8VO series. It is primarily used for power output and flow control in high-pressure hydraulic systems. Its core design incorporates Rexroth's proven industrial hydraulics technology, making it particularly suitable for applications such as construction machinery, mining equipment, and industrial machinery that require high power density and precise control. The following describes its technical features, model breakdown, and application scenarios:

Core Technical Features

Bend-Axis Design

Utilizing the bevel-axis axial piston principle, the piston is tilted at a predetermined angle (typically 25°) to the drive shaft. The reciprocating motion of the piston within the cylinder converts hydraulic energy into mechanical energy. This design tolerates large radial and axial loads, offers strong shock resistance, and is suitable for harsh operating conditions.

Variable Control Capability

Displacement Range: Nominal displacement is 160 cm³/rev (160 cubic centimeters of oil output per revolution). Flow can be continuously varied from 0 to maximum displacement by adjusting the swash plate angle, meeting flow requirements under varying operating conditions. Pressure Range:
Rated Pressure: 350 bar (continuous operating pressure)
Maximum Pressure: 400 bar (short-term peak pressure).
Speed Range: Adaptable to different drive systems, typically 1500-2100 rpm (specific values depend on operating conditions).
Built-in Auxiliary Pump and Control Function
Auxiliary Pump Configuration: An integrated pilot-stage auxiliary pump provides a stable, low-pressure control oil source (typically 20-40 bar) to drive the variable displacement mechanism of the main pump or an external control valve group, achieving pilot control.
Multi-Mode Control Options: Supports split power control (LA0/LA1), electrical proportional control (EP2), and load sensing control (LS), allowing flexible selection of control strategies based on system requirements.
Efficiency and Reliability
Volume Efficiency: ≥92% (efficient energy conversion, reduced leakage losses).
Durability: Utilizing wear-resistant coated plungers, high-strength bearings, and corrosion-resistant sealing materials, the system boasts a lifespan exceeding 10,000 hours. Easy Maintenance: The modular structure enables quick replacement of seals, bearings, and other wear parts, reducing downtime.

Typical Applications

Construction Machinery

Excavators: Provide high-pressure power for actuators such as the boom, arm, and bucket, suitable for models such as the Caterpillar E330B and E345L.

Shield Machines: Drive the grouting system and thrust cylinders, meeting the high-pressure and high-flow requirements of tunnel construction.

Concrete Pump Trucks: Precisely control concrete delivery volume, ensuring stable and continuous pumping.

Industrial Equipment

Injection Molding Machines: Provide high torque output for the mold clamping system, ensuring mold closing accuracy and rapid response.

Mining Crusher: Adapts to dusty and vibrating environments, driving crushing rollers for efficient ore crushing.

Ship Deck Machinery: Used in equipment such as anchor winches and winches, meeting the corrosion resistance requirements of marine environments.

Adaptable to Special Operating Conditions

Closed-Loop Systems: Can be combined with variable speed motors to form a closed-loop transmission, achieving precise speed regulation and energy recovery. High-pressure cleaning equipment: Maintains stable operation even in ultra-high-pressure environments of 50-100 MPa.

Selection and Maintenance Recommendations

Key Selection Points
System Parameter Matching: Calculate the pump's theoretical power based on the required flow, pressure, and speed (formula: Power = Pressure × Flow / 60), and allow for 20% redundancy.
Control Method Selection: Split power control (LA1) is suitable for multi-actuator coordinated operation, while electrical proportional control (EP2) is suitable for automation systems requiring precise flow regulation.
Installation Compatibility: Prefer SAE J617 flanges compatible with the equipment interface. Pay attention to the location and layout of the suction and drain ports.
Key Maintenance Points
Oil Management: Regularly test the oil cleanliness (NAS level 8 or higher is recommended) to prevent particulate wear on the plunger and manifold. When using mineral oil, maintain a viscosity between 16 and 36 mm²/s.
Leak Monitoring: Check the flow rate at the case drain port. An abnormal increase in flow may indicate seal failure. When replacing seals, use genuine spare parts to avoid dimensional deviations.
Preventive maintenance: Replace the hydraulic oil and filter every 2000 hours of operation, and check bearing clearance and swash plate wear.
