US 2013/0091833 A1 · Hydraulic control system and hydraulic control method

Abstract

A hydraulic control system and a hydraulic control method are disclosed. The hydraulic control system comprises a first closed pump (P1) and a first engine (M1) connected with each other, a second closed pump (P2) and a second engine (M2) connected with each other, and a hydraulic motor (P3). The first closed pump (P1), the second closed pump (P2) and the hydraulic motor (P3) are connected in parallel. Compared with the prior art, the present hydraulic control system has advantages of wider engine model selection range, higher reliability and better micro-motion performance.
