摘要
The hydraulic pump control system enables the synchronization of two independently mounted hydraulic lifting cylinders in a lift gate environment. A directional valve is added to the hydraulic line path between the lift cylinders and their respective pumps and reservoir tank. By connecting two pumps to one motor, the synchronization of the pumps is enabled for power up operations of the lift, and through the additional application of the directional valves, the oil flow rate to the lift cylinders (e.g., during a power down operation) can be maintained as hydraulically identical, thus synchronizing the movement of each lift cylinder with respect to the other, even in the presence other outside conditions that would could otherwise cause a de-synchronization of the lift cylinders.
