A2FM Series Axial Piston Pump
2 month ago
Product details
The A2FM Series Hydraulic Axial Piston Pump is a high-performance hydraulic pump widely used in construction machinery such as excavators, concrete mixer trucks, concrete pump trucks, pumping stations, paving machines, cranes, as well as industrial and agricultural machinery. This series of pumps has been widely recognized in the market for its stable operating performance, efficient energy conversion, and long service life.
Structural Characteristics
1. Pump Body Design: The pump body of the A2FM series is generally cylindrical, with circular grooves designed on its inner wall to fit with the plungers, ensuring that a sealed chamber is formed during the plunger's movement.
2. Plunger Assembly: The plunger is a cylinder that fits into the circular groove of the pump body to form a sealed chamber. The plunger is connected to the crankshaft and moves reciprocally in the circular groove as the crankshaft rotates. This design allows the pump to stably output hydraulic energy.
3. Inclined Axis Design: The A2FM series pump adopts an inclined axis design, which ensures smooth operation of the plunger rotor assembly during rotation, reducing vibration and noise, and improving the pump's efficiency and stability.
Working Principle
1. Oil Suction Process: When the plunger fits into the pump body, the oil in the sealed chamber is compressed, creating a low-pressure environment, and oil enters the sealed chamber through the suction port.
2. Oil Discharge Process: As the plunger moves circumferentially and moves away from the pump body, the oil in the sealed chamber is squeezed out, creating high pressure, and the oil is delivered to the system through the discharge port.
3. Flow Control: By adjusting the inclination angle of the plunger or changing the rotational speed of the crankshaft, precise control of the flow rate can be achieved to meet the needs of different working conditions.
Performance Characteristics
1. Stable Flow Transmission: Since the plungers of the axial piston pump are fixed, the transmitted oil volume is very stable, with little impact from the load, and the transmitted flow varies linearly with the rotational speed.
2. Little Deterioration: The plungers of the axial piston pump operate within a linear path, without significant impacts and vibrations, so the pump's degree of deterioration is small, and its service life is long.
3. Flexible Use: Multiple pumps can be integrated according to actual work needs, enabling various high-pressure, low-flow applications. Additionally, the compact design and high power density of this series of pumps make them more convenient to install and use.
4. Good Starting Characteristics: The one-piece plunger design with a plunger ring allows the pump to quickly reach a stable working state during startup, improving work efficiency.
Application Areas
With its excellent performance and wide range of applications, the A2FM Series Hydraulic Axial Piston Pump has become the preferred hydraulic pump for many industrial, agricultural, and construction machinery. In heavy-duty equipment such as excavators and concrete mixer trucks, this series of pumps can provide stable hydraulic energy to ensure the normal operation of the equipment; in projects such as pumping stations and paving machines, this series of pumps can efficiently transport liquids to meet construction demands.
