噪聲和振動
液壓裝置中容易產生噪聲的元件一般認為是泵和閥，閥中又以溢流閥和電磁換向閥等為主。產生噪聲的因素很多。溢流閥的噪聲有流速聲和機械聲二種。流速聲中主要由油液振動、空穴以及液壓沖擊等原因產生的噪聲。機械聲中主要由閥中零件的撞擊和磨擦等原因產生的噪聲。
（1）壓力不均勻引起的噪聲
先導型溢流閥的導閥部分是一個易振部位如圖3所示。在高壓情況下溢流時，導閥的軸向開口很小，僅0.003～0.006厘米。過流面積很小，流速很高，可達200米/秒，易引起壓力分布不均勻，使錐閥徑向力不平衡而產生振動。另外錐閥和錐閥座加工時產生的橢圓度、導閥口的臟物粘住及調壓彈簧變形等，也會引起錐閥的振動。所以一般認為導閥是發生噪聲的振源部位。
由于有彈性元件（彈簧）和運動質量（錐閥）的存在，構成了一個產生振蕩的條件，而導閥前腔又起了一個共振腔的作用，所以錐閥發生振動后易引起整個閥的共振而發出噪聲，發生噪聲時一般多伴隨有劇烈的壓力跳動。
（2）空穴產生的噪聲
當由于各種原因，空氣被吸入油液中，或者在油液壓力低于大氣壓時，溶解在油液中的部分空氣就會析出形成氣泡，這些氣泡在低壓區時體積較大，當隨油液流到高壓區時，受到壓縮，體積突然變小或氣泡消失；反之，如在高壓區時體積本來較小，而當流到低壓區時，體積突然增大，油中氣泡體積這種急速改變的現象。氣泡體積的突然改變會產生噪聲，又由于這一過程發生在瞬間，將引起局部液壓沖擊而產生振動。先導式溢流閥的導閥口和主閥口，油液流速和壓力的變化很大，很容易出現空穴現象，由此而產生噪聲和振動。
（3）液壓沖擊產生的噪聲
先導式溢流閥在卸荷時，會因液壓回路的壓力急驟下降而發生壓力沖擊噪聲。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間很短而產生液壓沖擊所致在卸荷時，由于油流速急劇變化，引起壓力突變，造成壓力波的沖擊。壓力波是一個小的沖擊波，本身產生的噪聲很小，但隨油液傳到系統中，如果同任何一個機械零件發生共振，就可能加大振動和增強噪聲。所以在發生液壓沖擊噪聲時，一般多伴有系統振 動。
（4）機械噪聲
先導式溢流閥發出的機械噪聲，一般來自零件的撞擊和由于加工誤差等產生的零件磨擦。
在先導型溢流閥發出的噪聲中，有時會有機械性的高頻振動聲，一般稱它為自激振動聲。這是主閥和導閥因高頻振動而發生的聲音。它的發生率與回油管道的配置、流量、壓力、油溫（粘度）等因素有關。一般情況下，管道口徑小、流量少、壓力高、油液粘度低，自激振動發生率就高。
