The axial piston pump is a swash plate type axial piston pump that uses an oil distribution plate to distribute oil, the cylinder rotates, and the variable head is used for variable displacement. The pump adopts the optimal oil film thickness design of hydraulic static balance, so that the cylinder and oil distribution plate, sliding shoe and variable head operate under pure liquid friction. It has the advantages of simple structure, small size, low noise, high efficiency, long life and self-priming ability.

Axial piston pump types:

Axial piston pumps are classified according to different movement directions, the contact mode between the plunger and the swash plate, the type of flow distribution mechanism, and whether the flow rate can be adjusted. For example, according to the relationship between the plunger movement direction and the axis of the transmission shaft, they are divided into straight-axis type and inclined-axis type. The following are common types of axial piston pumps:

1.Swashplate axial piston pump

2. Axial variable piston pump

3. Oblique axis axial piston pump

4.Hydraulic axial piston pump

5. High pressure axial piston pump

6.HY axial piston pump

7.CY axial piston pump

Axial piston pump model:

The axial piston pump model generally consists of nominal displacement, variable form, pressure level, motor, mechanism code, etc. Taking 63SCY14-1B as an example, it means: a manual variable cylinder rotating axial piston oil pump with a displacement of 63 ml/revolution and a pressure of 31.5MPa (that is, the nominal flow rate is 63L/min at 1000r/min)

Axial piston pump structure:

Axial piston pumps generally consist of a swash plate, return plate, cylinder block, oil distribution plate, drive shaft, sliding shoe, spring, plunger, inlet and outlet, etc. The following is a schematic diagram of the axial piston pump structure:

Remarks: 1-handwheel; 2-screw; 3-variable piston; 4-swash plate; 5-pin; 6-return plate; 7-sliding shoe; 8-plunger; 9-middle pump body; 10-front pump body: 11-front bearing; 12-distribution plate; 13-axis; 14-centering spring; 15-cylinder; 16-large bearing; 17-steel ball.

Working principle of axial piston pump:

When the axial piston pump motor drives the transmission shaft to rotate, the pump cylinder and the plunger rotate together, and the plunger head always remains in contact with the swash plate. Because the swash plate and the cylinder are at an angle, the plunger reciprocates in the pump cylinder when the cylinder rotates.

Taking the plunger of an axial piston pump as an example, when it turns from 0° to 180°, that is, to the position of the upper plunger, the volume of the plunger cylinder gradually increases, so the liquid is sucked into the cylinder through the suction port a of the oil distribution plate; and when the plunger turns from 180° to 360°, the volume of the plunger cylinder gradually decreases, so the liquid in the cylinder is discharged through the outlet of the oil distribution plate. As long as the drive shaft continues to rotate, the pump will continue to work.

Axial piston pump applications:

The axial piston pump has a variety of variable configurations to meet user requirements. It is widely used in machine tool forging, metallurgy, engineering, mining, shipbuilding and other machinery and other hydraulic transmission systems.
