油缸是液压压下的执行机构,要在承受轧制负荷的条件下工作,实现位置控制、压力控制和厚度自动控制。因此,油缸不但要求摩擦阻力尽量小,具有优良的动态品质,保证系统的快速性和稳定性,而且要具有一定的负载能力和足够的强度、刚度。 1.确定缸体外径油缸系高压厚壁容器,一般用厚壁筒公式确定 Cylinder is a hydraulic pressure actuator, to withstand the rolling load conditions, to achieve position control, pressure control and automatic thickness control. Therefore, the cylinder not only requires the friction resistance as small as possible, has excellent dynamic quality, to ensure the rapidity and stability of the system, but also to have a certain load capacity and sufficient strength and stiffness. 1. To determine the cylinder diameter cylinder system of high-pressure thick-walled containers, the general formula to determine the thick-walled cylinder
