Multi-channel hydraulic power flow coupling and matching system

Abstract

The invention belongs to the field of hydraulic power technology and relates to a multi-channel hydraulic power flow coupling and matching system. One end of a first hydraulic branch transmission gear is connected with a generator, and the other end of the first hydraulic branch transmission gear is connected with a first hydraulic branch bidirectional variable hydraulic pump to form a first hydraulic branch; a second hydraulic branch transmission gear is connected with a second hydraulic bidirectional variable hydraulic pump to form a second hydraulic branch; the first hydraulic branch and the second hydraulic branch are connected in parallel to a main oil way; a central controller is connected with the first hydraulic branch, the second hydraulic branch and the main oil way; both the first hydraulic branch bidirectional variable hydraulic pump and the second hydraulic branch bidirectional variable hydraulic pump are swash plate axial plunger pumps. The multi-channel hydraulic power flow coupling and matching system is simple in structure, reliable in principles and low in energy losses, has multiple functions for effectively reducing the energy matching losses of the hydraulic system, effectively reduces matching losses of traditional hydraulic systems due to oversupply of energy, and achieves residue hydraulic power recovery of the hydraulic system.

[0002] Hydraulic transmission technology has the characteristics of large power-to-mass ratio, fast response, self-lubrication, and easy connection with digital information networks. It has been widely used in industrial production, aerospace, and daily life, and has become the most important contemporary engineering technology. One of them, but the shortcomings of large power loss, low efficiency and wasting a lot of energy in hydraulic technology have not been effectively solved

The load sensing control technology with flow distribution pressure compensation measures on the multi-way valve makes the pressure difference on all valve ports in the hydraulic system consistent, and the proportional relationship between the working speeds of each actuator remains unchanged, thus ensuring the execution The accuracy of the action, but the working speed of its actuators is reduced
