Regarding vibration analysis in EDR

Thread Content

Dear experts, I have a few questions: 1. When calculating EDR, what does \"tube number\" mean in the vibration analysis report? In mechanical vibrations, it refers to values such as 1, 2, 4, 5, 6, 8； In the Resonance analysis, the values are 1, 1, 1, 2, 2, 2, 4, 4, 4, 5, 5, 5, 6, 6, 6, 8, 8, 8. I don’t know what they all mean. (2) In the vibration report, what do the locations of the vibrating pipes – inlet row, outer window, baffle overlap, Bottom Row, and inlet row end – mean? (3) The locations along the tube generally include inlet, Midspace, and outlet – what do these terms mean? 2. From what I understand, some companies, when calculating heat siphon reboilers, use EDR or HTRI to determine the parameters for vertical heat exchangers, and then manually calculate the installation height and driving force. I tried calculating it in this way as well, and found that when using a vertical heat exchanger and all vibration issues are taken care of, new vibration points emerge once switching to a siphon type heat exchanger.
