NL 系列活塞杆复合密封
                                                           NL 系列活塞杆复合密封
 
 
NL 型活塞杆密封由一个O型圈,加一个高强度PU密封圈和一个防挤出的挡圈三部分组成。单作用,嵌入沟槽稳定,
适合各种压力,抗载荷性强,允许较大的挤出间隙。
 
NLL 型活塞杆密封,采用特殊PU材料加工而成,实心结构使唇口外张贴紧密封表面,当使用压力大于30MPa时,应
加挡圈,最高工作压力可以达到70MPa。
 
应用范围
工作压力:P≤70MPa
工作温度:-30℃~100℃
表面速度:≤0.5m/s
工作介质: HFA水基乳化液
单作用活塞杆密封
 
安装
NL 型的活塞杆密封,通常安装于闭式沟槽中。在安装时,为了避免密封唇口被损伤,装配时请不要将密封件在锐边
上拉动。
 
材料
高强度密封圈采用特殊高性能耐水解PU材料,挡圈采用聚甲醛树脂,O型圈为NBR的材料制成。针对特殊要求(压力、温
度、速度等),请与我们联系,我们将推荐合适方案。
 
性能与用途
NL 型活塞杆密封,单作用,嵌入沟槽稳定,特殊的结构设计,抗高压,允许较大的挤出间隙耐压更高,广泛应用于煤矿支
护及大型综采设备。
