A2FM 60/61/63 and A2FE 60/61 Hydraulic Piston Pumps and Motors: Detailed Overview
I. Product Classification and Core Functions
1. A2FM Series (Swashplate Fixed-Displacement Motors/Pumps)
• Type: Swashplate axial piston motors/pumps with fixed displacement.
• Core Functions:
• Converts hydraulic energy (flow and pressure) into mechanical energy (torque and rotational speed), suitable for open or closed-loop hydrostatic transmission systems.
• Output rotational speed is proportional to flow rate and inversely proportional to displacement; output torque increases with the pressure differential between high-pressure and low-pressure sides, as well as displacement.
• Typical Applications: Construction machinery (e.g., concrete mixer trucks, rotary drilling rigs), mobile equipment (e.g., road rollers, cranes), and industrial machinery (e.g., rolling mill drives).
2. A2FE Series (Swashplate Variable-Displacement Pumps)
• Type: Swashplate axial piston variable-displacement pumps with adjustable displacement.
• Core Functions:
• Dynamically adjusts displacement based on system demands to optimize energy efficiency and response speed.
• Suitable for applications requiring flow control, such as load-sensing or pressure-compensated systems.
• Typical Applications: Injection molding machines, die-casting machines, and marine steering gear systems requiring precise flow control.
II. Technical Parameter Comparison
【表格】
Parameter A2FM 60/61/63 A2FE 60/61
Displacement Range 60/61/63 cm³/rev (fixed displacement) 60/61 cm³/rev (variable displacement)
Pressure Ratings 300/350 bar (standard)400/450 bar (high-performance)450/500 bar (ultra-high-pressure) Same as A2FM series, but variable design supports wider pressure range adjustment
Speed Range Up to 3000 rpm (depending on model and operating conditions) Up to 2500 rpm (more stable under variable control)
Power Density High (compact design, 26% smaller volume compared to 61 series) Relatively high (variable mechanism adds complexity but optimizes energy efficiency)
Efficiency Overall efficiency ≥92%, excellent starting efficiency Overall efficiency ≥90%, optimized for specific operating conditions under variable control
Noise Level Low (spherical port plate self-centers during rotation, reducing circumferential speed) Relatively low (optimized oil flow path)
III. Design Features and Advantages
1. A2FM Series
• Compact Design: Optimized precision in rotating components and port plate positioning, integrated built-in flushing valve, and 26% smaller volume compared to the 61 series.
• High Reliability: Spherical port plate design enables automatic centering during rotation, reducing wear; drive shaft withstands radial loads, adapting to harsh operating conditions.
• Easy Maintenance: Modular design supports rapid disassembly and reassembly, minimizing downtime.
• Multiple Pressure Ratings: Available in 300/350 bar, 400/450 bar, and 450/500 bar ratings to meet diverse application requirements.
2. A2FE Series
• Variable Displacement Control: Adjusts displacement infinitely via swashplate angle modulation, supporting constant power, constant pressure, and constant flow control modes.
• Energy Efficiency Optimization: Dynamically adjusts displacement based on load demands, reducing energy waste and system heat generation.
• Fast Response: High-speed proportional solenoids or hydraulic control valves enable rapid displacement switching for dynamic operating conditions.
• System Compatibility: Compatible with components like A4VG variable pumps to form efficient drive systems (e.g., snowplows, combine harvesters).
IV. Typical Application Scenarios
1. A2FM Series
• Construction Machinery: Drive systems for concrete mixer trucks, rotary mechanisms for drilling rigs, and vibration motors for road rollers.
• Industrial Equipment: Rolling mill screw-down systems, injection units in plastic machinery, and clamping mechanisms in die-casting machines.
• Mobile Equipment: Luffing mechanisms in cranes, power heads in drilling rigs, and steering gear systems in marine vessels (select models).
2. A2FE Series
• Injection Molding Machines: Controls injection speed and pressure via variable pumps to improve product quality.
• Marine Systems: Steering gear hydraulic systems adjust pump displacement based on navigation conditions to reduce energy consumption.
• Energy Sector: Pitch control systems in wind turbines precisely adjust blade angles to optimize power generation efficiency.
V. Selection Recommendations
1. Fixed Flow Requirements: Prioritize the A2FM series for its high power density and cost-effectiveness.
2. Dynamic Flow Control: Choose the A2FE series for energy optimization and precise control through variable displacement functionality.
3. High-Pressure Applications: Select models based on pressure ratings (e.g., 450/500 bar for行走驱动 systems in combine harvesters).
4. Space Constraints: The A2FM series’ compact design is ideal for applications with limited installation space (e.g., compact excavators).
