A20VLO pump is an axial - piston variable - displacement double - pump produced by Bosch Rexroth.
First, detailed introduction of A20VLO pump:
1.Structural and working principle: It adopts a swash - plate structure, with two sets of axial - piston rotating components. Driven by the drive shaft, the pistons in the cylinder block make reciprocating axial movements. By changing the angle of the swash - plate, the displacement of the pump can be adjusted, so as to realize stepless adjustment of the output flow between zero and the maximum value.
2. Main specifications: There are models such as A20VLO60, A20VLO95, A20VLO190, A20VLO260, and A20VLO520. Its peak pressure can reach 400 bar, and the speed can be as high as 2700 rpm.
3. Product features: It is composed of mature components of A11VO, A10VO/53, or A4VSO, with reliable quality. It can work in self - priming mode, pressurized fuel tank, and the working conditions with a built - in booster pump (specifications 190...360). It provides a variety of control devices, and the constant - power control can be set through an external adjustment device during the operation of the component (only applicable to power control). In addition, the pump can drive a gear pump or two axial - piston pumps through a through - shaft.
4. Application scenarios: It is suitable for hydrostatic drives in open - loop circuits, and is widely used in the hydraulic systems of agricultural machinery, mining, and marine machinery, as well as mobile and fixed equipment.
Second, differs from other types of pumps:
1.Structural features: Unlike centrifugal pumps that use impellers to generate centrifugal force for fluid transportation, and gear pumps that rely on the meshing of gears to convey fluid, the A20VLO pump adopts a swash - plate structure with two sets of axial - piston rotating components. This structure enables it to change the displacement by adjusting the swash - plate angle, thereby achieving stepless flow regulation.
2. Working principle: Positive - displacement pumps, such as gear pumps and vane pumps, change the working volume through the relative motion between the rotor and the pump body to transport fluid. The A20VLO pump belongs to the hydraulic pump category, which converts mechanical energy into hydraulic energy. It drives the pistons to make reciprocating axial movements through the rotation of the drive shaft, and realizes the suction and discharge of oil through the change of the cylinder volume, so as to output hydraulic power.
