液压螺旋压力机的液动机油腔由卸压状态转换为高压的压力瞬变过程中,若控制不当,必然会产生剧烈的液压冲击.本文分析了液动机作直线运动、螺旋运动和旋转运动的三种液压螺旋压力机液压冲击的控制机理及方法,建立了计算模型,可使液压系统具有运行平稳的优良特性.
Hydraulic screw press hydraulic fluid pressure chamber from the state of the pressure is converted to a high pressure transient process, if not properly controlled, will inevitably produce severe hydraulic shock.This paper analyzes the hydraulic linear motion, spiral motion and rotational motion Three kinds of hydraulic screw press hydraulic impact control mechanism and method, the establishment of a computational model, hydraulic system can run smoothly with excellent features.
