HUNGER活塞密封GD1000K系列應(yīng)用及作用
The Hunger slide ring piston seal type GD1000K is used to seal and guide pistons on double-acting hydraulic cylinders. The seal design and materials used make it particularly suitable for the most vigorous applications e.g. construction machine cylinders.
The seal can be used in standard form with mineral oils and water base fluids. Modified versions are available for use with other fluids.
The GD1000K consists of 6 parts, a special shaped elastic ring of a modified NBR, a slide ring of abrasion resistant PTFE-Bronze compound which acts as the sealing ring, two lateral support rings of modified PUR and two bearing rings of pressure-resistant POM PTFE-Bronze compound.
The elastic ring energises the slide ring to press it against the cylinder wall, providing a sealing function at zero working pressure. The onset of pressure compresses the elastic ring which increases the radial force pressing the slide ring against the cylinder wall, thereby increasing the sealing effect.
The two support rings prevent gap extrusion of the slide ring at high pressures. The special profile of the support rings encourages uniform fluid and pressure distribution to the elastic inner ring.
The bearing rings positioned on the support rings, make contact with the cylinder wall; there is no metallic contact between the piston and the cylinder tube.
When combined with a surface roughness of Ra 0.3 - 0.5 碌m of the cylinder, minimum friction is achieved. The seal has excellent efficiency. Even at low speeds there is no stick-slip effect allowing good positioning control.
HUNGER滑環(huán)活塞密封件GD1000K是用于密封和引導(dǎo)雙作用液壓缸上的活塞。所使用的密封設(shè)計(jì)和材料使其特別適用于最劇烈應(yīng)用場合，例如，施工機(jī)械油缸。
GD1000K由6個(gè)部件組成，彈性環(huán)使滑環(huán)能夠壓靠在氣缸壁上，在零工作壓力下提供密封功能。壓力的增加會(huì)壓縮彈性環(huán)，這增加了將滑動(dòng)環(huán)壓向氣缸壁的徑向力，從而增加了密封效果。
兩個(gè)支撐環(huán)防止滑環(huán)在高壓下的間隙擠出。支撐環(huán)的特殊輪廓可以使彈性內(nèi)圈產(chǎn)生均勻的流體和壓力分布。定位在支撐環(huán)上的軸承環(huán)與氣缸壁接觸;活塞和缸筒之間沒有金屬接觸。
當(dāng)與圓筒的Ra0.3-0.5μm的表面粗糙度相結(jié)合時(shí)，實(shí)現(xiàn)了最小的摩擦。即使在低速情況下，也不存在粘滑效應(yīng)，從而實(shí)現(xiàn)良好的定位控制。
