Research on the System of Power Feedback Hydraulic Pumps and Motors

The power matching between pump and motor in close system was studied, the form of power feedback was adopted in this system, thus using efficiency was elevated, the installed capacity was reduced.The gearbox in this system can make pumps and motors whose rotate speed are different work properly, while commutating feed equipment can ensure that pump and motor supply the oil properly under the condition of commutating work, at the same time, the problem of generating heat and filtering in the close system can be solved.
