The output control of oil.
Working method of the present utility model is：When converging valve disconnects, two oil circuits are independent oil supplies.Pressure sensor with
Flow sensor detects pressure and flow in oil circuit in real time, and the parameter feedback of acquisition is to control system.If necessary to increase wherein
The flow of one oil circuit, two oil feeding lines can be coupled by switching converging valve for conducting state, so as to realize double pump simultaneously
To an oil circuit fuel feeding, the merging of two-way oil feeding line exports, and increases the adjustable extent of hydraulic power supply.
The not described part of the present embodiment is same as the prior art.
