我厂三连在试制500吨粉末制品液压机过程中,遵照伟大领袖毛主席关于“打破洋框框,走自己工业发展道路”的教导,发扬敢想、敢干的革命精神,经过反复试验,创造了一种新的缸体试压用的高压密封结构(见图)。先将缸体粗加工,并把缸体的端面车成如图尺寸,两个缸体相对连接,可以省去盖板。双头螺栓用两个人的力量拧紧,端面的槽中用铅垫和φ5的“O”型橡胶圈密
In the process of trial production of 500t powder hydraulic press, our factory, in keeping with the teachings of Chairman Mao on breaking the foreign policy and the path of industrial development, carried forward the revolutionary spirit of daring to think and dared to do so after repeated trial and creation A new high pressure seal structure for cylinder pressure test (see photo). First roughing the cylinder block, and the cylinder into the car as shown in Figure size, the relative connection of the two cylinders, you can save the cover.
