避免系統(tǒng)發(fā)生共振
在液壓泵系統(tǒng)中常會(huì)發(fā)生振源(如液壓泵,液壓馬達(dá),電機(jī)等)引起底板,管道等部位發(fā)生共振;或是泵,閥等道等元件的共振而構(gòu)成較大的噪聲。對(duì)付這種現(xiàn)象,可通過改變管道的長度來改變管道的固有振動(dòng)頻率,和對(duì)一些閥的裝配位置結(jié)束改變措施來消除。

拒卻振動(dòng)
對(duì)付液壓系統(tǒng)中的緊張振源(泵,電機(jī))常采用加裝橡皮墊或彈簧等措施,使之與底板(或油箱)拒卻,也可采用將振源裝在底板上與全體系統(tǒng)拒卻的方法,這些都可收到良好的減振降噪的效果。
