Multiple control modes

Pump action process : When the engine power transmitted via flexible coupling spline shaft pump rotor to rotate. Meanwhile ,

the plunger reciprocates in the cylinder , the piston movement from the lower dead center to the top dead point of a stroke . When

each piston moving in the left direction with the oil pan half-cycle of 180 ° of rotation from the top dead point of the piston bottom

dead point motion . Volume becomes large , a certain degree of vacuum , the oil through the oil pan into the oil suction hole to

achieve a suction process, and the remaining half (180 °) rotation of the plunger toward the direction of movement of the oil pan ,

i.e., from the plunger dead point move up dead , the volume becomes smaller , the pressure oil through the oil pan drain out the

oil , drain realization process . Continuous rotation of the pump, the oil will continue to suck and discharge to complete energy

conversion , hydraulic oil to the hydraulic system , and promote the actuator motor or cylinder movement.

Determined by the size of the pump displacement piston stroke , and stroke size by pump swash plate angle α pendulum

impact , that the pump swash plate tilt angle α is large, larger piston stroke , the pump displacement increases, and vice versa , the

pump the swash plate tilt angle α from large to small , the piston stroke from large to small , the pump displacement is reduced.

When the tilt angle α is zero, zero displacement pump ( ie, zero displacement ) , the swash plate tilt angle α is changed by a servo

piston moves , the servo piston pump regulator controlled by the movement
