小型液压整形机是过去我们自行制造的设备,与ZS—7型三用阀试验台共用一套液压系统。由于液压系统齿轮油泵的额定工作压力低,致使油缸工作推力小,整形效果差。去年,我们因陋就简对该机油缸进行了改进,在原油缸的基础上叠加了一个油缸,改为液压增力油缸,比原油缸的工作推力增大80％。经过一年多时间的使用,效果良好,现介绍如下。 1.技术参数 该增力油缸的最大工作推力为100KN;增力缸直 Small hydraulic machine is the past, our own manufacturing equipment, and ZS-7-type three-valve test bed sharing a hydraulic system. As the hydraulic system gear pump rated working pressure is low, resulting in small cylinder thrust, plastic surgery poor results. Last year, we simply improved the cylinder because of its simplicity. We superimposed a cylinder on the basis of the original cylinder to convert it into a hydraulic cylinder with a force increase of 80% over that of the original cylinder. After more than a year of use, the effect is good, are presented below. 1. Technical parameters The maximum working thrust of the booster cylinder is 100KN; the booster cylinder is straight
