Title:
HYDRAULIC SYSTEM CONTROL METHOD AND APPARATUS, AND PETROLEUM MACHINERY
Document Type and Number:
WIPO Patent Application WO/2024/087508
Kind Code:
A1
Abstract:
A hydraulic system control method, comprising: determining a target displacement of a hydraulic pump and a target displacement of a hydraulic motor on the basis of the current working condition of a hydraulic system; acquiring a first transmission efficiency of the hydraulic system on the basis of the target displacement of the hydraulic pump and the target displacement of the hydraulic motor, and acquiring a second transmission efficiency of the hydraulic system on the basis of the current displacement of the hydraulic pump and the current displacement of the hydraulic motor; adjusting the displacement of the hydraulic pump and the displacement of the hydraulic motor on the basis of a comparison result of the first transmission efficiency and the second transmission efficiency, so as to achieve the optimal transmission efficiency of the hydraulic system. Also provided are a hydraulic system control apparatus and a petroleum machinery. The hydraulic system control method and apparatus can effectively improve the transmission efficiency of the hydraulic system.
