- World Engineer Day
Engineering innovations for a more resilient world - this year's World Engineering Day for Sustainable Development, also known as World Engineer's Day, will be celebrated under this slogan. It was adopted in November 2019 during the world congress of the World Federation of Engineering Organizations (WFEO) in Melbourne, organized jointly with UNESCO, which is the patron of this event. - Hydrogen - green gold. Opportunity or choice – or both?
In the article, we will try to provide an answer to the question of what hopes are associated with hydrogen. In 1875, the great 19th-century visionary Jules Verne wrote about it in The Mysterious Island: “So what will burn instead of coal? "With water..." "With water... With water will heat steamers and locomotives, with water to heat water?" in use. Yes, my friends, I believe that water will one day be used as fuel, that the hydrogen and oxygen of which it is composed, used separately or together, will become sources of heat and light, inexhaustible and possessing a power that earth coal cannot have. So there's nothing to be afraid of. Water is the coal of the future." - Experimental testing of pump units, taking into account the flexibility of foundations
The article presents the results of vibration analysis of the 40B80 pump in order to identify the causes of excessive vibrations. The research consisted in the measurement and spectral analysis of vibration signals in the motor and pump bearings in order to identify the harmonic components and their corresponding frequencies. Then, a numerical analysis of the frequency response of the upper foundation plate of the tested unit was carried out in order to check the influence of the natural vibrations of the foundation on the vibrations recorded in the bearings. Keywords: pump units, vibration analysis, harmonic components, bearings.
