注意事項

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

VICKERS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。威格士CG5V8FW0FMUH711電磁溢流閥石家莊總代理
