先導(dǎo)式溢流閥在卸荷時(shí)，會(huì)因液壓回路的壓力急驟下降而發(fā)生壓力沖擊噪聲。愈是高壓大容量的工作條件，這種沖擊噪聲愈大，這是由于溢流閥的卸荷時(shí)間很短而產(chǎn)生液壓沖擊所致在卸荷時(shí)，由于油流速急劇變化，引起壓力突變，造成壓力波的沖擊。壓力波是一個(gè)小的沖擊波，本身產(chǎn)生的噪聲很小，但隨油液傳到系統(tǒng)中，如果同任何一個(gè)

在先導(dǎo)型溢流閥發(fā)出的噪聲中，有時(shí)會(huì)有機(jī)械性的高頻振動(dòng)聲，一般稱它為自激振動(dòng)聲。這是主閥和導(dǎo)閥因高頻振動(dòng)而發(fā)生的聲音。它的發(fā)生率與回油管道的配置、流量、壓力、油溫(粘度)等因素有關(guān)。一般情況下，管道口徑小、流量少、壓力高、油液粘度低，自激振動(dòng)發(fā)生率就高。
