高压液压系统缸体的静密封至今一直采用带背环的O形圈.这一传统解决方案的基本缺陷是O形圈绳径的公差和直径无关.在大直径且高压峰值下,其不可避免的后果是渗流.为了避免这一情况的发生,利用单件、双重作用的聚氨酯压制的密封CoverSeal,开发出一种通用的解决方案,由此保证在大直径且高压下的全功能安全性.
The static seal of high-pressure hydraulic system cylinders has so far employed O-rings with back rings The basic drawback of this conventional solution is that the tolerances and diameters of the O-rings are independent of their diameter and are inevitable at large diameter and high pressure spikes The consequence is percolation.To prevent this from happening, a one-piece, dual-action polyurethane-sealed Sealing CoverSeal has been developed to provide a versatile solution that guarantees full-function safety at large diameters and pressures.
