Variable displacement axial piston pumps introduction:
Hydraulic variable displacement axial piston pumps are positive
displacement pumps that use multiple cylinders grouped around a
central axis. The group of cylinders are called a cylinder block.
The pistons within each cylinder are attached to a swash plate. The
swash plate is also known as a cam or wobble plate and attaches to
a rotating shaft. As the shaft turns, the angle of the swash plate
changes, which drives the pistons in and out of their respective
cylinders.
Hydraulic axial piston pumps main features:
1. Variable displacement axial piston hydraulic pumps
2. Axial piston hydraulic pumps have swash plate structure
3. Be suitable for hydrostatic transmissions with closed-loop
circuit
4. Manual servo and hydraulic variable control
5. Axial piston hydraulic pumps with a charging oil pump
6. LPV90 hydraulic variable displacement axial piston pump
7. Hydraulic piston pump 42Mpa high pressure
