Network optimization information:

Compared with the swashplate axial piston pump/motor, the swashplate pump/motor has the following advantages:

1) The lateral force of the plunger is much smaller than that of the straight shaft plunger. Therefore, the friction loss caused by lateral force is also very small.

The inclined axial piston pump/motor allows a greater cylinder swing angle. The swashplate angle of the oblique axial piston pump is generally about 20 °, while Hydraulic motor of pipe bender The oblique axial piston pump/motor can reach 402 °.) Since the spindle does not need to pass through the valve plate, the diameter of the distribution circle of the spherical valve plate can be smaller.

3) Since the mass of the rotating parts is small and the lateral force of the plunger is small, higher rotation speed is allowed.

4) Since the ball joint can be well fixed, it is conducive to the return of the plunger Axial plunger hydraulic motor Under the condition of self-priming, the inclined shaft type is allowed to operate under lower inlet pressure, and the self-priming performance is better than the swashplate type.

5) The overturning torque of the cylinder block is very small, the end face of the cylinder block is evenly bonded with the port plate, the leakage loss is small, and the volumetric efficiency is high; Low friction loss and high mechanical efficiency; And it is not very sensitive to oil pollution.

6) Due to the small moment of inertia of the rotating parts, the starting performance is good and the starting efficiency is high;
