HUNGER杆密封TDI系列描述及作用

Hunger TDI系列密封属于杆密封。它可以与矿物油一起使用，并且可以与水基液体，防火液体和压缩空气一起使用。TDI密封由两部分组成，一个带密封唇的PUR外部弹性环和一个带耐磨PTFE复合材料的内部滑环密封边缘。在配合之前，密封唇突出超过密封件的公称直径，并且当被压靠在活塞杆上时。由此，在零压力下提供有效的密封。

滑环产生一个环形腔，任何渗出的油都通过弹性体唇部被收集。渗漏油被密封边缘阻挡，使得出现的活塞杆保持干燥。在那里转弯时，被收集的油被迫回到了圆筒。

密封件的内密封面主要由内滑环组成，具有良好的滑动性能。与表面结合使用时在活塞杆上的Ra为0.1-0.3µm，实现了最小的摩擦等级，密封效率高，使用寿命长。没有停滞，最重要的是没有粘滑效应。

The Hunger TDI tandem seal for inside sealing is a piston rod seal.

It can be used with mineral oils and in modified ｆorm with water base fluids,

fire resistant fluids and compressed air.

The TDI seal consists of 2 parts, an external elastic ring of PUR with a sealing lip and an internal slide ring of abrasion resistant PTFE-Bronze compound with a

sealing edge. Prior to fitting, the sealing lip protrudes beyond the nominal diameter of the seal and when fitted is pressed against the piston rod. Effective sealing is thereby provided at zero pressure.

The slide ring is surrounded by the elastic ring and seals axially in direct contact with the piston rod. Under increasing pressure and compression of the sealing

ring, it is the slide ring which is predominantly pressed against the piston rod. The slide ring produces an annular cavity where any seepage oil that has passed

the elastomer lip is collected.

The seepage oil is held back by the sealing edge such that the emerging piston rod remains dry. During there turn stroke, the collected oil is forced back into the

cylinder.

The internal sealing surface of the seal primarily comprises the internal slide ring which possess excellent sliding properties. When combined with a surface finish

of Ra 0.1 - 0.3 µm on the piston rod, minimum frictionlevels 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.
