Abstract
根据本发明组装的一种包括玻璃纤维填充件的消音器,该消音器可避免产生玻璃纤维碎屑并防止其进入流体通道,因而适用于封闭的制冷系统,一多孔管依次被一抗热织物覆盖层、一玻璃纤维填充件和一沿周向可调节收缩的套筒所覆盖,它们作为一子组件插入到一高压容器的壳体内。
Description
与内燃机消音器不同,用于制冷压缩机的消音器是处在一个具有制冷气体的封闭系统内的,而这些制冷气体又是处在额定的压缩机排放温度和压力之下。新的制冷剂必须被压缩到较高的压力以达到与CFC和HCFC制冷剂相同的制冷能力,因此工作压力约为400psi。因而,位于制冷系统内并处在压缩机外的一制冷压缩机消音器是处在一个高压容器内的,该消音容器对结构整体性的要求远大于对内燃机消音器的要求。这便需要使结构有所变化以达到更高的要求,并且在制造和装配过程中也作出相应的变化。
吸收式消音器(常被称作衬管)通常用在空气分配系统中,偶尔也可用在内燃机排气场合,特别是当需要降低较高频率的噪声和压力脉动时比较适用。尽管它们的声学特性较佳,但是因为在制冷系统的环境下存在着种种特殊问题,所以在带有容积式压缩机的制冷系统中基本上不使用这种吸收式消音器。原因是:1)由于系统是封闭的而且包含了很多精密构件,因而制冷剂流的清洁度以及不带碎屑是很重要的,这样才能使系统正确的工作;2)消音器通常位于压缩机的排放处,而该排放处则是在较高的压力和温度之下(在现时一般使用的制冷剂中压力达到400psi),因此该消音器必须能处在一高压容器中;3)大多数系统是封闭的,而且通常是靠焊接和/或铜焊系统的金属构件(包括消音器的壳体)来达到系统的封闭的,因而,吸收材料必须能够承受装配过程中的高温而不会被损坏;4)通常的压缩机排放流中含有大量的润滑油,它们趋向于浸润所用的吸收材料,受此浸润的吸收材料仍必须有合适的声学特性,这便意味着根据过去出版的标准所选择的材料并不一定有效;5)很多新的替代CFC和HCFC的制冷剂以及需要和它们一起使用的特种油都具有活泼的化学性质,因而会损害很多传统使用的吸收材料;以及6)由于流动流体有严重的脉动,所以对消音器的内部施加着一个较大的流体动力,使得传统构造的材料品质下降而且最终有分解的趋势。
因此,与传统的吸收式消音技术相比,在技术上需要作出变化,即,选择与传统不同的材料、在结构上作出变化、在制造和装配技术上作出相应的改变。
预成形的玻璃纤维填充件围绕穿孔的内管,该管子适于和压缩机的排放端相连,在玻璃纤维填充件和管子之间加上一层结实并且能承受高温的织物材料层。一个薄金属片套筒围绕着填充件,该套筒具有搭接边,因此可沿周向压缩。填充件的材料,例如用特殊的粘接剂和密度远低于传统的已有技术中所用材料的预成形玻璃纤维,在受到润滑剂的浸润时还是具有所需的声学特性,并且同时与必要的制冷剂和润滑剂化学兼容。套筒具有多个沿周向间隔、且沿轴向延伸过其大部分长度、并且从套筒径向向外延伸的凸脊。诸凸脊被设计成一定的尺寸、数量和间隔,以在将套筒压配入外部高压容器时,为玻璃纤维填充件提供一个合适的预压力。在将组件压配到位时,诸凸脊的圆的端部提供了一个凸轮作用,而同时诸凸脊又形成了与高压容器的内壁面接触较少的接触面,因而降低了压配时的阻力。由于玻璃纤维由套筒覆盖和保护,因此不会由于和高压容器的内壁面相刮擦而产生玻璃纤维碎屑。还有,在压配过程中,玻璃纤维不会相对内管偏移。
本发明的一个目的在于,在保持装配便利的同时,能在消音器的填充件上提供一预加的压力。
本发明还有一目的在于,提供一种既可在装配过程中又可在有严重脉动流的工作情况下,防止易碎的玻璃纤维因受到多孔内管的摩擦而造成摩擦损伤的装置。
本发明的另一个目的在于,提供一种可经济地对玻璃纤维填充材料预加压的装置。这些和其它一些目的将通过下文对本发明所作的描述而变得更加明显。
基本上,由多孔内管、布套层、围绕着的玻璃纤维填充件和预压套筒组成了一个子组件。预压套筒可沿周向收缩,并且在其外表面上具有沿周向间隔及沿轴向延伸的诸凸脊,这样,当通过压配合将该子组件装配到高压容器中时,子组件和容器之间的接触面就被限制为诸凸脊和容器内表面之间的接触。
图1是本发明消音器的分解立体图;
图2是消音器的剖视图;
图3是套筒的端视图;
图3A和3B是图3中一部分的放大视图。
在图1和图2中,标号1O总的表示根据本发明技术制成的一消音器。消音器10包括一高压容器12,它是由气密地焊接在一起的壳体12-1和端盖12-2及12-3所组成的。从图2清楚可见,端盖12-2和12-3分别收合了联接器14和15,该两联接件是铜焊定位以形成消音器组件10中的子组件。多孔管20在消音器10内,它包括多个孔20-1,其标定直径为O.125英寸,并在管子20上占据了约40%的开口面积。管子20收合联接器14和15的内端,并且和它们一起构成了一个穿过消音器10的流体通道。多孔管20的外表面覆有一层作为过滤器的材料,它主要是防止碎屑进入管子20再进而进入封闭的制冷循环系统,并且保护玻璃纤维不受管子20,特别是不受穿孔20-1的磨损或类似影响。抗火/抗热的芳族聚酰胺纤维材料Nomex(商标)布适于用作覆盖在管子20外表面的套筒或覆盖层22。覆盖层22最好是有边的并且是缝合的。可以用加有酚醛粘合剂的玻璃纤维来形成具有两个半圆筒形的环状圆筒形式的填充件。半圆筒24-1和24-2共同形成了覆盖在覆盖层22上的环状圆筒形式的填充件24。
从图3,3A和3B清楚可见,预压套筒30是一个金属薄片制成的套筒,该套筒上带有均匀地沿周向隔开、占了其大部分长度的诸隆起的凸脊30-3。边缘30-1搭接在边缘30-2上形成重叠或搭接缝,而过渡部分30-4既可以提供搭接密封,又可以避免在搭接处产生凸起。边缘30-1和30-2可沿周向彼此相对地移动,以扩开或收缩套筒30的周缘。套筒30有一个额定的第一直径,而诸凸脊30-3则有效地形成了一个较大的第二直径。套筒30的自由直径大于壳体12-1的孔径。
在组装消音器10时,将有边并缝合的覆盖层22覆盖在多孔管20上。将由玻璃纤维填充件24组成的半圆筒24-1和24-2覆盖在覆盖层22上,形成一个子组件,继而将它装在预加压套筒30中。如上所述,预加压的套筒30可周向地调节,因此它可以容易地胀开以覆盖在由管子20、覆盖层22和填充件24所构成的子组件上。套筒30套覆在填充件24上后,套筒30和其下方覆盖的填充件24被充分压缩,以使套筒30的端部可以插入高压容器1 2的壳体12-1,或者,反过来先将壳体12-1套覆在套筒30上。由于诸凸脊30-3的直径大于套筒30的其余部分,因而需要进一步压缩套筒30和填充件24以使诸凸脊30-3可以进入。诸凸脊被设计成一定的尺寸、数量和间隔,以为玻璃纤维填充件提供一合适的预加压力。此外,因为诸凸脊30-3的端部是圆的,所以它们充当了将套筒30导入壳体12的凸轮同时又使接触面积减少以便于将套筒30压配入壳体12-1中。应该可以很清楚的是,在将含有填充件24、覆盖层22和管子20的套筒30插入到壳体12-1中时,不会因为刮擦填充件24的外表面而产生碎屑。还有,搭接的边缘30-1和30-2一方面可以将套筒30进行压缩以使其插入壳体12-1,同时,搭接的边缘30-1和30-2也可以使对壳体12-1的内径、套筒30的厚度、凸脊30-3的高度和填充件24的外径等公差要求不那么严格。在任何时候,当联接器14和15都分别铜焊在端盖12-2和12-3上,套筒30、填充件24、覆盖层22和管子20被放置到壳体12-1中,包含联接器14和15的端盖12-2和12-3被焊接在壳体12-1的一定位置上时,就可以以形成高压容器12并且消音器10随之也就制成了。
总之,本发明可组装和使用这样一种消音器,它在一封闭制冷系统中使用了一种玻璃纤维填充件,但并不产生玻璃纤维碎屑,或者是任碎屑进入封闭的制冷系统。
尽管上面已经描述并说明了本发明的一个较佳实施例,但对本技术领域的熟练人员而言还可能作出其它的变化。例如,可以用间隙配合但是固定的零件来进行最初的装配,而玻璃纤维则是通过管子20的扩张来加压的。因此,本发明的保护范围仅受所附权利要求书中阐述的内容所限。
