DO型是一种常见的浮动油封设计,由两个类锥型截面的密封环和两个O型圈组成

详细介绍

DO型是一种常见的浮动油封设计,由两个类锥型截面的密封环和两个O型圈组成。

优点:

---设计可靠

---有效封隔外界的灰尘、水、泥污、并保护内部的润滑油和润滑脂

---成本低、效率高

---安装定位简单

---更长的使用寿命

---自动补偿轴的偏心

适用场合

浮动油封用途广泛,通常被推荐使用于速度慢的、对润滑可靠性和寿命要求高的场合。例如:它能用于:

矿山设备:重型卡车、电铲、钻机、采煤机、刮板输送机、筛选机、破碎机等。

工程机械:液压挖掘机、推土机。

农业机械:轮式拖拉机、耕地机、挖沟机、割草机。

材质:

意大利GNL公司浮动油封金属环的材料通常是符合UNI3097标准的合金钢100Cr6,硬度为HRC58—HRC63;橡胶圈的材料通常为丁腈橡胶。

工作条件:

工作压力:≤3 bar

工作温度:-30---+110 °C(NBR) -25---+200 °C(FPM)

表面速度:≤3m/s

表面粗糙度:与密封环接触的表面粗糙度建议为Ra4.0-6.5。

安装指导:

---清洗腔体件,清除任何残留物,沟槽的所有棱边必须光滑。

---只能在安装前打开浮动油封的原始包装,取出密封件。

---检查O型环的位置,不能扭曲变形,把密封件的一半放入腔体的入口,均匀的压入腔内,可用无水乙醇湿润沟槽和橡胶圈以便于安装,严禁使用润滑油或者润滑脂等辅助安装。

---检查安装后沟槽外表面和密封面是否平行,偏差为1MM,O型环在沟槽中不能有任何起伏和突出。

---在将两边密封环压紧,清洁密封面,并在密封面上用无棉绒的抹布涂一层薄油膜。

---完成安装后检查间隙,计算压缩量。

备注:如果密封组件在维修时被分开,即使还未达到磨损极限,也必须重新安装新的密封组件。因为运行之后接触面在较短的时间内会沿一个共同的轨迹运行,再重新安装时无法保证安装在原位置,密封面的磨损路径不再匹配,就会发生漏油,直到密封面在此磨合为止。
