多年来,我厂维修YB32—100吨四柱万能铸铝压机活塞密封圈,始终为一大难题。过去更换时,用一台三叉架以手拉葫芦将上横梁(包括缸体)吊起,翻身放下装上密封圈,完毕后翻身吊起,再用同样顺序装到油压机上。这种方法工作量大,效率低,维修不便。 针对上述问题,我设计了一种过桥圈,见图1,并借助它来进行装配,见图2,直接卸掉上柱宽上的拼 Over the years, I plant maintenance YB32-100 tons four-cylinder universal aluminum pressure piston seals, has always been a major problem. In the past when the replacement, with a trifurcated chain hoist (including the cylinder) hoist, stand up and put down the ring, after the turn stand up, and then loaded to the hydraulic machine in the same order. This method of heavy workload, low efficiency, maintenance inconvenience. In response to the above problems, I designed a bridge ring, see Figure 1, and use it to assemble, see Figure 2, the direct removal of the fight on the column width
