一、性能与用途 由一个低磨擦的填充聚四氟乙烯(ptfe)环和o形橡胶密封圈组合而成,o形圈提供足够的密封预紧力,并对ptfe环的磨耗起补偿作用。ptfe摩擦系数小,动静摩擦系数相近。适用于高低速往复运动及高压系统的油缸活塞杆密封。采用两个阶梯圈密封,可达到零泄露。一般要和导向环配套使用。轴径小于φ30的规格,应采用分体式沟槽。 二、材 质 阶梯圈为填充聚四氟乙烯ptfe,o形圈为丁腈橡胶nbr或氟胶fkm。 三、工况条件 耐 压:0-40mpa; 往复速度:≤5m/s; 工作温度:丁晴nbr:-30~+120℃,氟胶fkm:-20~+200℃; 工作介质:液压油、气、水(在磷酸酯液压油中选用氟胶)。 四、设计标准 本系列符合gb/t 15242.1-94及gb/t 15242.3-94标准。可参考parker公司od系列、merkel公司-oms-mr及霞板公司s55013系列。 五、标注方法 轴用阶梯圈用订货号来标注,示例:gsj-1000 ptfe+nbr 六、结构装置 |
