材料和技术Materials and Technology For Aerospace Industry

规范和批准Specifications and Approvals
对于航空航天应用,许多设计是复合密封件,其中弹性体元件是密封件的组成部分因此,必须仔细控制弹性体膨胀、成型收缩、压缩永久变形、介质相容性和公差等参数。For aerospace applications many designs are composite seals, with an elastomer element as an integral part of the seals. It is therefore important that parameters such as elastomer swell, shrinkage during molding, compression set, media compatibility and tolerances are carefully controlled.

通过稳定的工艺和我们实验室100%的批量测试,我们确保材料的制造符合Trelleborg密封溶液的规格作为美国政府和航空航天工业支持计划的一部分,一些材料也被批准用于合格产品清单(QPL)Through stable processes and 100 percent batch testing in our laboratories, we make sure that the materials are manufactured to Trelleborg Sealing Solutions specifications. A number of materials have also been approved for a Qualified Products List (QPL) as part of US government and Aerospace Industry support programs.

化学相容性Chemical Compatibility
弹性体材料比其他密封化合物对流体更敏感化学反应会损坏密封,影响物理性能特别是在液压应用中,为给定的液压流体选择最佳弹性体材料至关重要不仅要考虑使用的机油,还要考虑添加剂,因为这些添加剂会导致不良行为可能需要在高温下进行浸泡试验,以验证应用中的性能Elastomer materials are more sensitive to fluids than other sealing compounds. Chemical reaction can cause damage to the seal, affecting physical properties. Specifically in hydraulic applications, selection of the optimum elastomer material for a given hydraulic fluid is critical. Not only must the oil used be taken into account but also the additives, as these can cause adverse behaviour. It may be necessary to conduct a soak test at elevated temperature in order to verify the performance in application.

温度范围Temperature Range
Turel化合物可在-73°C至+260°C/-100°F至+500°F的温度下工作。因此,大多数化合物将满足AS4716 II型系统的温度要求,规定为-54°C至+135°C/-65°F至+275°F。使用弹簧通电的Variseal可进一步扩大温度范围此外,对于高温应用,IsolastJ8325的工作温度高达+325°C/+617°F。Turel Compounds are available to operate in temperatures from -73°C to +260°C / -100°F to +500°F. Most will therefore meet the temperature requirements of AS4716 type II systems, specified as -54°C to +135°C / -65°F to +275°F. The use of spring- energized Variseal can expand the temperature range even further. In addition, for high-temperature applications, Isolast J8325 has an operating temperature up to +325°C / +617°F.

温度循环Temperature Cycling
温度循环对弹性体密封的影响会导致压缩永久变形这意味着弹性体材料随着时间的推移失去弹性对于Turel材料,如果指定用于工作温度在指定参数范围内的应用,则该影响保持在可接受的最小值低温动态循环极限随弹性体类型而变化。The effect of temperature cycling on elastomer seals can result in compression set. This means that the elastomer material loses its elasticity over time. For Turel materials, this effect is kept to an acceptable minimum if they are specified for applications with operation temperatures within the indicated parameters. The low-temperature dynamic cycling limits vary according to elastomer type.

低温Cold Temperatures
特瑞堡密封溶液中的弹性体材料是专门设计的,以在寒冷条件下获得最大的性能。Elastomer materials from Trelleborg Sealing solutions are specifically engineered to give maximum performance in cold conditions.

在寒冷环境中,弹性体材料收缩约是钢的十倍。材料在低温下变硬,失去弹性。当通过下限时,它达到玻璃化转变阶段,当它变得极其脆弱当温度再次升高时,物理性质将恢复增加挤压可以改善低温性能。Elastomer materials contract approximately ten times more than steel in cold environments. The material becomes stiffer and loses its flexibility at cold temperatures. When passing the lower limit it reaches the glass transition stage, when it becomes extremely brittle. Physical properties will recover when temperatures elevate again. Increased squeeze can improve performance at low temperatures.

高温Hot Temperatures
如果超过温度上限,弹性体材料就会软化并失去物理性能物理性能不会恢复,密封件将承受永久压缩永久变形压缩永久变形也随弹性体所接触介质的类型而变化持续暴露在高于推荐温度的环境中可能会永久损坏密封件。Elastomer materials soften and lose their physical properties if the upper temperature limit is exceeded. Physical properties will not recover and the seal will take on a permanent compression set. The compression set also varies with the type of media to which the elastomer is exposed. Continuous exposure to temperatures higher than those recommended can permanently damage the seal.

表面速度Surface Speed
通常,与弹性体密封接触的动态表面速度应保持在9.8 ft/s/3 m/s以下,以避免对弹性体造成损坏。In general, the speed of the dynamic surface in contact with an elastomer seal should be kept below 9.8 ft/s / 3 m/s to avoid damage to the elastomer.

老化Aging
最大的推荐储存和货架时间可以在我们的航天密封系统产品目录和工程指南中看到。这些值仅在弹性体在控制条件下储存在防光和密封包装中时有效。The maximum recommended storage and shelf time can be seen in our Aerospace Sealing Systems Product Catalog and Engineering Guide. These values are only valid if the elastomer is stored under controlled conditions in light-proof and airtight packaging.

OrkotSlydring和轴承Orkot Slydring & Bearings

Orkot材料由特殊的热塑性树脂制成,浸渍有精细编织纤维的织物复合材料。Orkot materials are made of special thermoplastic resin impregnated with a fabric composite of fine weave fibers.

对于存在高侧负荷的动态液压系统中的杆和活塞应用,OrkotSlydring轴承可以充当导环,以保持往复和旋转部件的正确定位和同心度使用OrkotSlydring可防止运动部件之间的金属对金属硬件接触,并消除硬件的刻痕和磨损,从而提高系统寿命和可靠性。For rod and piston applications in dynamic hydraulic systems where high side loads are present, Orkot Slydring bearings can act as guide rings to maintain correct positioning and concentricity of reciprocating and rotating components. Use of Orkot Slydring prevents metal-to-metal hardware contact between moving parts and eliminates scoring and fretting of hardware, resulting in improved system life and reliability.
