Working principle
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. The outlet flow of the pressure-compensated variable pump varies with the constant pressure curve within a certain range with the size of the outlet pressure. When the high-pressure oil from the main body part enters the lower cavity (d) of the variable housing through the channels (a), (b), (c), the oil enters the channels (f) and (h) through the channel (e), respectively. When the force of the spring is greater than the hydraulic thrust from the oil passage (f) into the annular area at the lower end of the servo piston, the oil passes through (h) to the upper cavity (g) and pushes the variable piston downward to increase the flow of the pump. When the hydraulic thrust on the annular area at the lower end of the servo piston is greater than the force of the spring, the servo piston moves upward, blocking the passage (h), and allowing the oil in the (g) cavity to pass through the (i) cavity to release the pressure. At this time, The variable piston moves up, the variable head deflection angle decreases, and the flow of the pump decreases. When adjusting the flow characteristics, you can first screw the limit screw to the upper end, adjust the spring sleeve according to the required range of flow and pressure change, so that the initial pressure when the flow begins to change meets the requirements, and then tighten the limit screw to the end The flow rate at the stage pressure no longer changes, and the relationship between the flow rate and the pressure change is determined by the design of the pump.
