O-ring美国国家标准(AS568)

不同国家O型圈标准不同国家对于O型圈的标准并没有明确的统一要求，每个国家都可能有自己的规定和标准。

以下是一些国家对于O型圈的一般要求的概述。

1.日本标准日本国家标准（JIS）对于O型圈的标准规定在JISB2401中。

根据这个标准，O型圈的尺寸是根据内径（d1）、外径（d2）和厚度（d3）来计算的。

具体的尺寸要求可以在JISB2401中找到，并且根据不同的应用有不同的型号和等级。

2.美国标准美国标准协会（ANSI）制定了一些标准来规范O型圈的尺寸和材料。

其中比较常用的是AS568标准，该标准规定了20种不同尺寸的O型圈，分别标记为AS568-001至AS568-020。

这些标准根据内径、截面直径和厚度来进行分类。

3.德国标准德国国家标准（DIN）也有一些关于O型圈的标准。

DIN3771是一种常见的O型圈尺寸标准。

它使用内径（d1）和交叉截面直径（d2）来定义O型圈的尺寸。

4.英国标准英国标准协会（BSI）也有一些标准用于规范O型圈。

BS1806是一种常见的O型圈尺寸标准，它使用内径（d1）和交叉截面直径（d2）来定义O型圈的尺寸。

此外，BS4518还规定了一些O型圈的尺寸和材料要求。

除了以上的国际标准外，不同国家可能还有自己独特的规定和标准。

例如，中国国家标准（GB）有一些关于O型圈的标准，常用的包括GB/T3452.1-2005和GB1235-76、这些标准规定了O型圈的尺寸范围、材料要求和性能测试方法。

总的来说，不同国家的O型圈标准在尺寸、材料和性能上可能存在差异。

因此，在选择O型圈时，需要根据具体的应用需求和国家标准进行选择。

此外，还需要注意使用符合标准要求的工具和设备进行安装和测试，以确保O型圈的质量和性能符合要求。

0型圈有关知识及规格编写方法一、O-ring的定义O-ring，中文名O型密封圈或者O型圈。

是一种截面是圆（或者说是O）的橡胶密封圈，其主要作用是密封，如气密封、水密封、油密封等。

二、O-ring 的表示方法O型圈的规格标记方法有两种：一：内径ID（inner diameter）*线径CS（cross section）二：内径ID*外径OD（outside diameter）但第一种标记方法比较通用。

三、O-ring的规格O型圈在国际上比较通用的规格标准有美标AS568A、国标GB3452.1-82、日标JIS B-2401等等。

（具体各规格的尺寸型号可参考扩展阅读中的O-RING规格表）四、O型圈的材质选用A、材质表材料名称化学描述英文缩写英文别名丁腈胶丙烯腈－丁二烯橡胶NBR Buna-N氢丁腈胶氢化丙烯腈－丁二烯橡胶HNBR HNBR三元乙丙胶乙烯－丙烯－二烯橡胶EPDMEP,EPT,EPR氯丁二烯氯丁二烯橡胶CRNeoprene硅胶硅树脂橡WMQ PVMQ氟硅氧烷氟硅酮橡胶FVMQ FVMQ丙烯酸酯丙烯酸酯橡胶ACM ACM乙烯丙烯酸乙烯－丙烯酸橡胶AEM Vamac苯乙烯-丁二烯苯乙烯-丁二烯橡胶SBR SBR聚亚安酯聚酯/聚醚氨酯AU/Eu AU/EU 天然橡胶天然橡胶NR NR 以上为O 型圈较常NBRHNBREPDMFKMCR ACMAESBRAU/EUVMQFVMQNR的材质分类，其中最常用的事丁腈胶，因为其综合性能较好，且价格比较低，是性价比最高的O型圈材质。

O 形密封圈的选用一、概述 特点：O 形密封圈由于它制造费用低及使用方便，因而被广泛应用在各种动、静密封场合。

标准：大部分国家对O 形密封圈都制定系列产品标准，其中美国标准（AS 568）、日本标准（JIS B 2401）、国际标准（ISO 3601/1）较为通用。

安装时其径向和轴向方面的预压缩赋与O形密封圈自身的初始密封能力。

它随系统压力的提高而增大。

性能参数：静态密封动态密封工作压力无挡圈时，最高可达20MPa；有挡圈时，最高可达40MPa；用特殊挡圈时，最高可达200MPa。

无挡圈时，最高可达5MPa；有挡圈时，较高压力。

运动速最大往复速度可达0.5m/s，最大旋转速度可达2.0m/s。

度一般场合：-30℃～+110℃；特殊橡胶：-60℃～+250℃；旋温度转场合：-30℃～+80℃介质见《橡胶密封件原料特性表》。

二、O形密封圈选择应考虑的因素1、工作介质和工作条件在具体选取O形圈材料时，首先要考虑与工作介质的相容性。

还须综合考虑其密封处的压力、温度、连续工作时间、运行周期等工作条件。

若用在旋转场合，须考虑由于摩擦热引起的温升。

不同的密封件材料，其物理性能和化学性能都不一样，见《橡胶密封件原料特性表》。

This series has traditionally utilized the significant dash numbering system, wherein the dash number designates the tube size in 16th’s of an inch. This practice is also followed here, with the exception of the -901, which is intended for a 0.0938 inch (2.38 mm) nominal OD (outside diameter) tube, the 0.0625 inch (1.59 mm) OD tube not being in common aircraft use.2.4In the interest of standardization, it is requested that companies or agencies do not use the dash numbers in Table 1 to which sizes have not been assigned. Sizes not assigned are indicated by an asterisk (*).

气动密封o型圈标准英文回答：Pneumatic Seal O-Ring Standards.Pneumatic seal O-rings are essential components in a wide range of pneumatic systems, providing a reliable and effective seal to prevent leakage and maintain system performance. To ensure proper functioning and compatibility, these O-rings must meet specific standards that definetheir dimensions, materials, and performance characteristics.ISO 3601-1:2017。

ISO 3601-1:2017 is the international standard that specifies the dimensions and tolerances for O-rings used in pneumatic applications. This standard covers both metricand inch sizes, with a range of cross-sectional diameters and thicknesses. It also includes requirements for thesurface roughness and hardness of the O-ring material.AS568A.AS568A is an American National Standard that provides specifications for O-rings used in aerospace applications. This standard includes a wide range of sizes, materials,and performance requirements, including those for pneumatic seals. AS568A O-rings are designed to meet the demanding conditions found in aerospace systems, such as high pressure, extreme temperatures, and corrosive environments.Material Selection.The choice of material for a pneumatic seal O-ring depends on the specific application requirements. Common materials include:Nitrile (Buna-N): Offers good resistance to oil, fuels, and solvents.Fluorocarbon (Viton): Provides excellent resistance tohigh temperatures and chemicals.Silicone: Has good flexibility and low-temperature resistance.Polyurethane: Offers high wear resistance and durability.Performance Characteristics.In addition to dimensions and materials, pneumatic seal O-rings must also meet specific performance requirements, including:Leakage rate: The amount of leakage that occurs through the O-ring at a given pressure.Friction: The force required to overcome the friction between the O-ring and the sealing surface.Temperature range: The temperature range over which the O-ring can operate effectively.Pressure range: The pressure range within which the O-ring can maintain a seal.Proper Installation and Maintenance.To ensure proper functioning and longevity of pneumatic seal O-rings, it is critical to follow proper installation and maintenance procedures. This includes:Selecting the correct O-ring size and material for the application.Inspecting the O-ring for any damage or defects before installation.Lubricating the O-ring and sealing surface to reduce friction.Regularly inspecting and replacing O-rings as needed to maintain system performance.中文回答：气动密封O型圈标准。
