Detailed understanding of the structure and working principle of hydraulic piston pumps

1. The input shaft of the pump connected to the driving source rotates, and the cylinder block connected to the input shaft rotates through a spline.

At this point, the piston sliding on the inclined plate moves back and forth according to the angle of the inclined plate.

3. When the piston of the cylinder block protrudes, oil is sucked in from the oil tank, and when it protrudes, it is ejected towards the valve actuator side

Oil. According to the valve plate, it is divided into suction port and discharge port. The larger the inclination angle of the variable pump inclined plate, the greater the stroke of the piston's reciprocating motion. When the angle is 0, the piston does not engage in reciprocating motion and the discharge flow rate is also 0.

3. When the circuit pump is turned off and an angle in the opposite direction is added, even if the rotation of the input shaft is the same, the suction and discharge will be reversed
