METHOD FOR DISTRIBUTING HYDRAULIC OIL FLOW OF HYDRAULIC SYSTEM AND DEVICE THEREOF

摘要

Disclosed are a hydraulic oil flow distribution method and a device thereof for hydraulic system. The hydraulic system includes multiple oil passages and an oil pump from which hydraulic oil is supplied to the multiple oil passages. The method includes the following steps of: calculating the hydraulic oil flow supplied by the oil pump by a first hydraulic oil flow calculating device (10), calculating the hydraulic oil flow required for the multiple oil passages by a second hydraulic oil flow calculating device (20), and calculating the ratio between the supplied hydraulic oil flow and the required hydraulic oil flow when the hydraulic oil flow supplied by the oil pump is less than the hydraulic oil flow required for the multiple oil passages, and regarding to each of the multiple oil passages, supplying the hydraulic oil flow which is the product of the oil flow required for the oil passages and the ratio to the passage. By proportionally distributing the hydraulic oil flow to each oil passage, the hydraulic oil flow distributed by the system to each oil passage reduces accordingly. Therefore, though the action of the actuation component corresponding to each oil passage is slow, it is able to coordinate action and complete composite motion.
