德國HUNGER桿密封TDI系列描述及作用
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.
Hunger TDI系列密封屬于桿密封。它可以與礦物油一起使用，并且可以與水基液體，防火液體和壓縮空氣一起使用。TDI密封由兩部分組成，一個帶密封唇的PUR外部彈性環(huán)和一個帶耐磨PTFE復(fù)合材料的內(nèi)部滑環(huán)密封邊緣。在配合之前，密封唇突出超過密封件的公稱直徑，并且當(dāng)被壓靠在活塞桿上時。由此，在零壓力下提供有效的密封。
滑環(huán)產(chǎn)生一個環(huán)形腔，任何滲出的油都通過彈性體唇部被收集。滲漏油被密封邊緣阻擋，使得出現(xiàn)的活塞桿保持干燥。在那里轉(zhuǎn)彎時，被收集的油被迫回到了圓筒。
密封件的內(nèi)密封面主要由內(nèi)滑環(huán)組成，具有良好的滑動性能。與表面結(jié)合使用時在活塞桿上的Ra為0.1-0.3μm，實(shí)現(xiàn)了最小的摩擦等級，密封效率高，使用壽命長。沒有停滯，最重要的是沒有粘滑效應(yīng)。
