Scientists of the high-tech products exchange centre of Pyongyang University of Mechanical Engineering have recently developed a technique for diagnosing the vibration of rotary machines.
According to Kim Su Gwan, lead developer, PhD and associate professor, compressors, electric generators, motors and different kinds of rotary machines in operation generally vibrate due to the effect of temperature change, voltage variation, axial transformation and wear.
Such vibration lowers the performance of machinery and equipment, causes many hindrances to production and forms a cause of trouble.
Therefore, to correctly analyze and assess the change of running rotary machines in real time arises as an important matter in preventing troubles and ensuring their performance and lifespan.
That is why many countries are interested in the research into it. Especially, cutting-edge technologies are actively being developed and applied to diagnose the operational features of equipment and take necessary steps by promptly analyzing and assessing the vibration of machines.
Kim Su Gwan and other scientists completed a new analysis and assessment method that can find out in time and take a measure for abnormal conditions of rotary machines in operation by means of a diagnosing method based on mathematic modelling.
When the new technique is applied, operators can swiftly and correctly diagnose and predict trouble factors by measuring and analyzing in real time the vibrations caused by imbalance of the body of revolution, discord of shaft centre and wear of slide bearing revealed in operating high-speed rotary machines including steam-power generators, motors, compressors, blowers and exhausters and high-speed machine tools.
