本刊一九八○年第五期曾刊登了上海油泵油咀厂陈梅青同志介绍的《一种平衡油缸》,这种油缸结构简单,体积小,不需要油泵供给压力油,有一定的实用价值。但由于加工困难,仅适合一些立置部件移动距离较短的设备。因为立置部件如果要移动较长距离,油缸体和活塞杆也要相应加长,从加工工艺角度来考虑,油缸体如直径不大,长度又长,其内孔的表面
The publication of the fifth issue of 1980 has published a “balanced cylinder” introduced by Comrade Chen Meiqing of Shanghai Pumping Tsui Factory, which has the advantages of simple structure, small volume, no need of oil pump to supply pressure oil and has certain practical value . However, due to processing difficulties, only some of the vertical components move a short distance equipment. Because the legislature parts to move a longer distance, the cylinder body and the piston rod should be lengthened accordingly, from the processing point of view, the cylinder body, such as small diameter, long length, the surface of the inner hole
