Forging machinery (such as pipe bending machines, hydraulic presses, bending machines, etc.). Metallurgical machinery, port machinery and other industries.
Advantages of LA4VSO Axial Piston Variable Pump
Variable flow control
The primary advantage of an axial piston variable pump is its ability to adjust the flow rate of the hydraulic fluid. This allows for precise control of hydraulic systems, enabling efficient operation and energy savings.
High efficiency
Axial piston variable pumps offer high volumetric and overall efficiencies, minimizing energy losses and maximizing system performance.
Compact design
Despite their power and versatility, axial piston variable pumps are relatively compact, making them suitable for applications where space is limited.
Reliability and durability
These pumps are designed to withstand high pressures and continuous operation, ensuring reliability and durability in demanding applications.
Working Principle of Axial Piston Variable Pump
To convert mechanical energy into hydraulic output, an axial piston pump utilizes a rotating, splined drive shaft that connects to and turns a piston barrel. To create the pumping mechanism of the pump, piston pumps can use either a swash plate design (featured in video) or a bent axis design.
In both designs, as the pistons rotate they are repeatedly drawn away from a valve plate and then pushed closer to the valve plate. This variation in distance alters the size of the chamber available to hold hydraulic fluid. At times when the gap between the end of a specific piston and the valve plate is decreasing, the chamber will shorten, and hydraulic fluid will be expelled through the valve plate. As the piston rotates, it will eventually reach a point where the gap is increasing, leading to a longer chamber. This vacuum will cause hydraulic fluid to be drawn into the chamber through the valve plate.
Since the valve plate acts as a divider between the input and output sides of the pump, as the pistons and piston barrel rotate, hydraulic fluid will be continuously cycled through the pump as it is drawn from one connection and directed with force into another.
Since the rotating of the pistons and piston barrel is determined by the rotation of the shaft, the pump's output can be controlled by increasing and decreasing the speed of the shaft. In the swash plate design, further control of the pump is possible by adjusting the angle of the swash plate, changing the distance of the pistons from the valve plate, and, in turn, increasing or decreasing the size of the chamber available to hold hydraulic fluid.
Bearings
Bearings on the shaft allow the shaft to rotate inside the housing of the pump with reduced friction.
Shaft
The shaft distributes mechanical, rotational force to the pump. Splines on the shaft interconnect with splines in the piston barrel to turn the barrel and pistons while splines on the part of the shaft that extends from the housing connect to the machine.
Pistons
Pistons inside the pump rotate around the center shaft. Since the plane at which one end of the piston is attached is set at an angle determined by the swash plate, the pistons also vary their distance from the valve plate as they rotate. This variation causes a continuous alternation in the depth of the cavity available to hold hydraulic fluid inside the piston barrel and leads to their continuous looping through the pumping process.
Swash plate
In an axial piston pump utilizing a swash plate design, the swash plate is responsible for setting the angle of the piston's container and, in turn, the amount of variation in depth the pistons will move through. Altering the angle of the swash plate allows the action of the axial piston pump to be further controlled.
Piston barrel
The piston barrel contains the pistons and defines the center cavities through which hydraulic fluid moves as it creates the pumping flow.
Valve plate
The valve plate sits on the end of the piston barrel opposite the pistons. Slots in the valve plate allow fluid to be directed to specific connections for intake and discharge.
Application of Axial Piston Variable Pump
Mobile hydraulics
These pumps are widely used in mobile hydraulic systems of construction equipment, agricultural machinery, and material handling equipment.
Industrial machinery
Axial piston variable pumps power hydraulic systems in industrial machinery, such as machine tools, presses, and injection molding machines.
Marine and offshore
They are employed in hydraulic systems of ships, offshore platforms, and subsea equipment, providing reliable and efficient fluid power.
Renewable energy
Axial piston variable pumps are utilized in renewable energy systems, such as wind turbines and solar tracking systems, for precise control and efficient operation.
Considerations When Choosing Axial Piston Variable Pump
When selecting an axial piston variable pump, consider the following factors:
Flow rate and pressure requirements
Choose a pump that can deliver the required flow rate and pressure for your specific application.
Control type
Axial piston variable pumps can be controlled manually, mechanically, or electronically. Select the control type that best suits your system's needs.
Speed range
Consider the speed range of the pump to ensure it can operate effectively at the desired speeds.
Environmental conditions
Take into account the environmental conditions, such as temperature, humidity, and contamination levels, to choose a pump with suitable seals and materials.
