Information × Registration Number 0216U007158, 0116U000352 , R & D reports Title A recommendations for further effective operation basing on diagnostics and determination of current technical conditions of electrical machines located in a shop for roll manufacturing. popup.stage_title Head Zagirnyak Mykhaylo, Registration Date 07-04-2016 Organization Kremenchuk Mykhaylo Ostrogradskiy State University popup.description2 The analysis was carried out on the base of a shop for rolls manufacturing, consisting of four technological lines with productivity of 2.5 million tons of rolls per year for one line. In technological process it is used equipment by U.S. manufacturer Allis Chalmers worked by principle "grating - pipe heater - annular cooler". Object of research - technical conditions of induction electric drives of technological mechanisms of first technological line of a shop for rolls manufacturing, which consists of 20 units. Research was carried out according to requirements of state standards for measurements, tests and analysis of operating and exploitation modes of electrical machines. The diagnostics of technical conditions and evaluation of current operation effectiveness of electrical machines was carried out basing on diagnostic methods by current and power consumption spectra analysis, method for indirect determination of induction motors' energy features and shaft power. Basing on carried out diagnostics and analysis it was detected motors which worked under fault conditions, and also recommendations for further effective exploitation of induction motors were given.
