Systém diagnostiky stavu ventilátoru odsávání pánvové pece

Abstract

The Master Thesis focuses on technical diagnosis of dust-collecting appliance fan of constant steel casting. First of all, the principle of dust-collecting appliance including the fan is explained. Secondly, there is description of components and possible errors of the fan with negative influence on its technical condition and suggestion of possible methods of technical diagnosis. Due to variability of the device, the best method is supposed to be multiparametric diagnosis (vibrodiagnostics and thermodiagnostic). Vibrodiagnostics is the main diagnosis method during which absolute vibration of the device is measured and analyzed (trend analysis, frequency analysis and envelope method) and brings sufficient information about technical condition of the fan. Thermodiagnostic is considered to be used as additional method applied during stronger vibrations resulting from electromotor.
