斜轴式变量柱塞泵

The main body (see the structural section) drives the cylinder to rotate by the transmission shaft, so that the seven plungers evenly distributed on the cylinder rotate around the centerline of the transmission shaft, and the slide shoes in the column slide assembly are pressed against the variable head ( Or swash plate). In this way, the plunger reciprocates with the rotation of the cylinder to complete the oil suction and oil pressure actions.


Inclined shaft variable plunger pump This variable type pump, when the output pressure is less than the set constant pressure, the full displacement output pressure oil, that is, the quantitative output, is automatically adjusted when the output oil pressure reaches the set pressure Pump flow to constant pressure to meet the requirements of the system. The output constant pressure value of the pump can be adjusted steplessly within the pressure adjustment range according to the requirements. The structure of the pump is shown in Figure 6. This structure simultaneously sends the output pressure oil to the lower cavity of the variable piston and the control oil of the constant pressure valve. At the inlet, when the output pressure is less than the set constant pressure, the oil pressure thrust on the constant pressure valve core is less than the set spring force, the constant pressure valve is open, the pressure oil enters the upper cavity of the variable piston, and the variable piston pressure is low. Position, the pump discharges pressure oil at full displacement; when the pump works at constant pressure setting, the hydraulic thrust on the constant pressure valve core is equal to the setting spring force, and the inlet and outlet ports of the constant pressure valve are open at the same time. The hydraulic thrust of the upper and lower chambers of the variable piston is made equal, and the variable piston is balanced to work at a certain position. If the hydraulic damping (load) is increased, the oil pressure rises instantaneously, the oil outlet of the constant pressure valve opens, and the oil inlet closes. In the upper cavity of the variable piston, the pressure in the lower cavity decreases, the variable piston moves upwards, and the flow rate of the pump decreases until the pressure drops to the set constant pressure. At this time, the variable piston works in a new equilibrium position. Conversely, if the hydraulic damping (load) decreases, the oil pressure drops instantaneously, the oil inlet of the constant pressure valve opens large, and the oil outlet closes, the oil pressure in the upper cavity of the variable piston rises, and the variable piston moves downward. The flow rate is large until the pressure rises to the constant pressure setting.
