The research work considers and analyzes the problem of control valve failure in case of shaft-gear break during normal operation. In order to identify typical deviations and causes of failure of the electrically driven valves. the amplitude-frequency spectra of the current signal taken at one or more phases of the electric motor were analyzed. The method of spectral diagnostics adopt... https://thegreensjunglebeautyshops.shop/product-category/hair-care-kits/
