超高压油缸的密封技术是发展超高压液压机的技术关键。本文论述油缸在超高压压力作用下,缸壁径向变形对密封装置的影响和采用“承支环”补偿缸壁径向变形的密封装置。
EHV cylinder sealing technology is the development of high pressure hydraulic machine technology key. This paper discusses the cylinder under the effect of ultra-high pressure, the cylinder wall radial deformation of the seal device and the use of “bearing ring” to compensate for the radial deformation of the cylinder wall seal.
