Abstract: Disclosed is a flow control system for digital and mechanical redundant pressure compensation. On the basis of an original pressure compensation valve, two-position three-way electromagnetic valves are added to control the opening and closing of pressure compensation valves. Furthermore, pressure sensors and a controller are added, so that the system has a digital pressure compensation function. When the pressure sensor breaks down, the flow control system is switched to a mechanical compensation mode to achieve mechanical pressure compensation, the problem that system flow cannot be controlled when the sensor breaks down is solved, and the purpose of redundancy control is achieved. Moreover, the pressure compensation valve in the loop where the highest load is located can be controlled to be completely opened through the two-position three-way electromagnetic valve to reduce pressure loss of the valve port, and the pressure is not affected by load fluctuation.
