Design Description:The DAQ piston seal is a double-acting seal, also ptfe seals,with a PTFE sealing ring and a star-shaped ring responsible for dynamic sealing, while an O-ring provides static sealing.
设计说明：
DAQ活塞密封件是双作用密封，四氟滑环与星形圈一起承担动态密封功能，而O形圈完成静态密封功能。
DAQ 活塞密封件专为需要保持压力的高速高压工况而设计。建议用于双作用活塞、活塞式储能系统、支撑缸和定位缸。
DAQ 提供低摩擦和高弹性的双重安全性，提供出色的动静密封性能，它们可以容纳更大的挤压间隙，同时有效保持压力，从而最大限度地减少液压缸中的泄漏。
沟槽设计简单，安装空间小，滑动性能优良，无爬行现象。
标准材料
•密封环:填充聚四氟乙烯F-PTFE
0形圈 ： 丁腈橡胶NBR或氟橡胶FKM
星形圈：丁腈橡胶NBR或氟橡胶FKM
应用范围
广泛应用于机床，压机，蓄能器，稳定器，重型悬挂油缸等设备中。
