電動閥的噪音控制辦法

人氣:0發表時間:2019/12/12 0:00:47

電動閥的噪音控制辦法:

  1.運用消音器

  消音器只需直接安裝在控制閥的下流,就能有用減低控制閥的噪音。不過,在運用消音器時,常常會遇到一些題。首先,消音器要有用,就需要低流速。但低流速卻往往使消音器顯得無實用價值,特別是在大流量體系中更是這樣。其次,音響要素常常和流體介質不相配合。第三,操作條件或許大惡劣。

  2.進步管道的標號

  添加下流管道的管壁厚度,可以有用減低控制閥的噪音。不過,因為噪音一旦發生,并不敏捷沿著下流管道長度散失,因此,這一辦法一般有必要用在整個下流體系上。

  3.管道隔絕法

  這一辦法,和添加管道管壁厚度的辦法相同,也可以有用減低電動閥所產生的噪音。不過,有必要留意三個約束。第一,和改變管道標號的辦法相同,隔絕法也有必要用在整個下流體系上。第二,有必要細心安裝隔絕資料,免得資料變成“無功效”,以致嚴峻減低這一辦法的有用性。第三,一般用于管道體系的隔熱辦法,其減低噪音的有用性是有限的。因為合適的資料往往不適用于高溫,所用的粘合劑或許熔化,從根本上改變了自身的音響質量和熱力特性。
