Abstract：

Some key technologies and engineering issues about the design principle, structure, seal and installation of 400 MN cylinder on XIAN Triangle Aviation Technology Co., Ltd., and the 300 MN cylinder with 90 MPa super highpressure on Suzhou KUNLUN Heavy Manufacture were discussed. Through previewing the development for heavy hydraulic press in the world, the matter that the super heavy hydraulic cylinder was the key factor for promoting the development of heavy hydraulic press was introduced in detail. The design principle and related technical problems of the super heavy hydraulic cylinder by Bumpyridge prestressed of steel wire were analyzed.
