# 派克 OR 系列旋转组合密封，Polon® > 用于旋转分配器等的旋转密封应用。动密封面在内测。双向作用，密封面/滑环为聚四氟乙烯设计。低摩擦。适合耐高压应用 ISO 7425 所属技术：密封技术 ## 系列介绍 用于旋转分配器的密封,生产厂商都比较喜欢采用简单的密封结构。这可以用内侧密封的OR型组合旋转密封来实现。OR型组合密封由一个耐磨、低摩擦的滑环和一个作为施力弹性体的橡胶O形圈组成。它主要适用于系统压力从密封件一侧到另外一侧交替的应用,如旋转履带的心轴,回转接头,软管卷绕轮以及液压机床。如果此密封件用于端部密封,建议在端部使用防尘圈。由于其工作条件,OR型旋转组合密封会开有一条或两条的储油槽/润滑槽。 • 出色的密封性能,仅需要非常小的装配空间。 • 非常优异的耐磨性。 • 更小的启动摩擦和动态摩擦力,没有爬行现象,哪怕是很低的速度时保持匀速平稳运动。 • 低摩擦以便其具有良好的能效。 • 对压力峰值不敏感。 • 选配合适的O形圈可耐高温。 • 由于储油槽的作用是密封面保持着良好的润滑。 • 耐挤出性能高。 • 由于滑环具有非常好的耐化学性,加之O形圈有众多材料选择,使得OR几乎能耐化学介质。 • 轴向装配长度短。 • 可安装在封闭或开放式沟槽。 • 可供直径从4 mm到3000 mm。 • 车削加工,尺寸丰富,货期较短。 派克OR型组合旋转密封有以下材料可供选择: 033 030 074 052 314 083 025 0V6 016 027 ## 技术参数 | 参数 | 值 | 单位 | | --- | --- | --- | | 介质 | 液压 | | | 聚合材料选件 | 聚四氟乙烯（PTFE），超高分子量聚乙烯（WHMWPE），聚氨酯（TPU）, Ultra-High Molecular Weight Polyethylene (UHMW-PE), Thermoplastic Polyurethane (TPU, Resilon®, Ultrathan®) | | | 最大运行压力 | 300 bar | | | 最低运行温度 | -260 至 -25 °C | | | 最高运行温度 | 80 至 300 °C | | | 最大表面速度 | 1 , 0.5 m/sec, 1.0 m/sec | | | 测量单位 | Length: mm | | | 缓冲机制 | 否 | | | 热应用类型 | 扩展的高温（\>205C） °C, 标准的常见温度范围（-35 到 100 摄氏度) °C, 扩展的低温和高温（\<-35 C 到 140 C） °C | | | 额定压力 | 高压（\<500 bar） bar | | ## 型号入口（首批） -
