德國(guó)HUNGER活塞密封TDMA系列應(yīng)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。它可以與礦物油一起使用,也可以與壓縮空氣一起使用。
TDMA密封由兩個(gè)部分組成。在安裝之前,密封唇突出超過(guò)密封件的公稱直徑,并在裝配后壓靠在汽缸壁上。因此即使在零壓力下也能提供有效的密封。滑動(dòng)環(huán)由彈性體密封環(huán)圍繞,并沿軸向與管內(nèi)部直接接觸。隨著彈性環(huán)的壓力和壓力的增加,滑動(dòng)環(huán)主要壓在管的內(nèi)部。 TDMA的外密封面主要由滑動(dòng)性好的滑環(huán)組成。
當(dāng)在缸筒或活塞桿上結(jié)合Ra 0.3 - 0.5μm的表面光潔度時(shí),可獲得最小的摩擦等級(jí),且密封效率高,使用壽命長(zhǎng)。
沒(méi)有粘滯,沒(méi)有很高的熱量產(chǎn)生,最重要的是沒(méi)有粘滑效應(yīng)。 TDMA密封推薦用于需要分離每側(cè)不同流體的場(chǎng)合。
它也適用于密封油脂室防止水或其他流體的進(jìn)入。
