德国HUNGER活塞密封TDMA系列应用及作用
The Hunger TDMA tandem seal for multi-fluid outside sealing application is used to seal pistons and plungers. It can be used with mineral oils and in modified form with compressed air.
The TDMA seal consists of two parts, an elastic ring of PUR with 2 sealing lips and a slide ring of abrasion-resistant PTFE-Bronze Compound with 2 sealing edges. Prior to fitting, the sealing lips protrude beyond the nominal diameter of the seal, and are pressed against the cylinder wall after fitting. Thus effective sealing is provided even at zero pressure. The slide ring is surrounded by the elastomer sealing ring and moves axially in direct contact with the inside of the tube. With increasing pressure and compression of the elastic ring, it is the slide ring which is predominantly pressed against the inside of the tube. The outer sealing surface of the TDMA mainly comprises the slide ring which has excellent sliding properties.
When combined with a surface finish of Ra 0.3 - 0.5μm on the cylinder tube or the piston rod, minimum friction levels are achieved with highly efficient sealing and long service life.
There is no stiction, no unacceptable heat generation and above all no stick-slip effect. The TDMA seal is recommended for use where different fluids on each side are to be separated.
It is also suitable for sealing grease chambers against the ingress of water or other fluids.
Due to its good dry running properties, it can be used as a fluid seal on one side and simultaneously as a dirt wiper on the other side.
Hunger TDMA系列密封用于密封活塞和活塞。它可以与矿物油一起使用,也可以与压缩空气一起使用。
TDMA密封由两个部分组成。在安装之前,密封唇突出超过密封件的公称直径,并在装配后压靠在汽缸壁上。因此即使在零压力下也能提供有效的密封。滑动环由弹性体密封环围绕,并沿轴向与管内部直接接触。随着弹性环的压力和压力的增加,滑动环主要压在管的内部。 TDMA的外密封面主要由滑动性好的滑环组成。
当在缸筒或活塞杆上结合Ra 0.3 - 0.5μm的表面光洁度时,可获得最小的摩擦等级,且密封效率高,使用寿命长。
没有粘滞,没有很高的热量产生,最重要的是没有粘滑效应。 TDMA密封推荐用于需要分离每侧不同流体的场合。
它也适用于密封油脂室防止水或其他流体的进入。
