Highland mining machinery industry axial piston pumps high pressure
Axial piston pumps introduction:
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.
Axial piston pumps main features:
1. Variable displacement axial piston pumps
2. Axial piston 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 pumps with a charging oil pump
