6) rectangular seals
矩形密封圈
1.
The results indicate that the contact pressure of sealing face of the rectangular seals increases with the increase of initial compressibility or liquid pressure.
结果表明,矩形圈密封面处的接触压力随初始压缩率和液体压力的增加而增大;矩形圈较O形圈的接触压力均匀、密封面大、密封效果好且初始压缩率小、老化速度慢、尺寸稳定性好,但矩形密封圈的接触面积大,散热效果差,只能用于静密封。
