·Product Details: Rexroth Rexroth A4VG High Pressure Piston Pump Series
- Displacement from 28 to 250
- Common pressure 400bar (40Mpa)
- Peak pressure 450bar (45Mpa)
Rexroth A4VG features:
Swashplate axial piston variable displacement
pump for closed circuit hydrostatic transmission
◆The flow rate is proportional to the drive speed and displacement and can be steplessly variable;
◆ The flow increases from zero to its maximum with the swashplate swing angle;
◆The swashplate can be placed in the middle position to smoothly change the flow direction of the liquid flow;
◆ A variety of variable methods that are easy to match with various control and regulation systems;
◆The
pump is equipped with two relief valves on the high pressure oil side to protect the hydrostatic transmission (
pump and motor) from overloading;
◆The high pressure relief valve also has the function of the charge valve;
◆ Built-in auxiliary
pump is used as charge
pump and control
pump;
◆ The maximum charge pressure is limited by a built-in charge relief valve;
◆The whole series has built-in pressure shut-off valve;
typical application:
Concrete
pump truck, heavy hydraulic flatbed truck, hydraulic
pump station
Technical Para
meters:
Numerical table (theoretical value, ηmh and ηv are not considered; the value is rounded)
1) Maximum speed: - The power consumption is half of the angular power (for example, when Vg man and PN/2)
2) High maximum speed: - When running at high speed and no load
- During engine overspeed: Δp=70...150 bar and Vg max
- For reverse peak load: Δp < 300 bar and t < 5 seconds.
