The slices of the bispectrum and trispectrum are plotted for the vibration signals of the speed control value when it works both under normal condition and under fault condition. 摘要為了解決液壓元件調速閥故障診斷難的問(wèn)題，采用三譜及其切片分析的方法，針對調速閥閥體正常和故障時(shí)的振動(dòng)信號，分別繪制出其雙譜切片和三譜切片圖。
Speed Control Valves are available for controlling valve opening or closing speed with pneumatic actuators. 速度控制閥可以用來(lái)控制閥門(mén)氣動(dòng)執行器的開(kāi)啟或關(guān)閉速度。
