Methods of Accumulator's Buffering Against Hydraulic Shock from Inertia Load
摘要
Abstract
The gasbag-type accumulator plays a major role in buffering hydraulic shock.The hydraulic system of the mucking loader's big ann in blast furnace is analyzed as an engineering example.The cause analysis of hydraulic shock is elaborated,and the mathematic model of shock pressure is built,and the measures of reducing hydraulic shock are summarized.We take a theoretical analysis of the working process of the accumulator and the hydraulic circuit in which the accumulator is used to buffer hydraulic shock.Meanwhile,we build the simulation model and take a simulation study of the system,and focus on the influence of accumulator's preload pressure and volume on moderating hydraulic shock.Finally,we apply the proposed methods to measure the ends' pressure curves of the drive motor.The measured results can verify the effect of the accumulator's buffering against hydraulic shock.关键词
