此系统应用小波降噪的方法提高测试信号的质量,然后提取信号特征点,得到溢流阀动态特性的各项参数。
Applying wavelet denoise to improve the test signal, the dynamic characteristic parameters of a overflow valve were obtained by selecting characteristic point of the signal.
The accuracy of traditional spectrum analysis for the diagnosis of reciprocating pump valve is not satisfied for the interference of the noise and the vibration of the adjacent parts.
