Closed-variable pump-controlled multi-motor walking hydraulic system for super-large overweight transfer equipment
The working conditions requires very high in a certain production line for oversized and overweight materials during production and transportation,especially for walking drive systems require stability,reliability,low energy consumption,and low installed power.This article compares and analyzes the principles and technical characteristics of traditional commonly used proportional valve controlled motor synchronous walking hydraulic systems and closed pump controlled multi motor walking hydraulic systems.Taking the closed pump-controlled multi-motor hydraulic system as the experimental object of the production line test bench,the oil pressure of motor inlet and outlet are researched during the loading and stopping process of the motor,which provides guidance for the mass production and use of the closed-type pump-controlled multi-motor walking hydraulic system of super-large overweight transfer equipment.
