Large vertical vibration velocity

However, there are also many cases with only parameters available and no confirmed diagnosis. I also struggled with such problems for a long time,,, A large company assigned experts from various fields, who brought along various modern instruments to conduct thorough inspections of the equipment; finally, they identified the areas that needed testing and provided the relevant data, with the conclusion being that there was nothing more to be done. In the end, the problem is solved through conventional analysis and investigation. The best way to look up such problems is to start by checking the following aspects. 1. The foundation of the equipment and the prestress used for connecting it involve horizontal, even force application for a secure connection; the quality of the secondary grouting is important, as well as whether the shims are installed properly ； 2. What is the dynamic balance of the equipment’s rotor? ； 3. Whether the bearing is damaged, and whether the oil supply pressure at the oil supply point is normal ； 4. Whether the levelness of the rotor and the bearing clearance meet the requirements ； 5. Is the process operation under control within the requirements of the operating range? For reference.

If the vertical vibration is greater than the horizontal vibration, check first for any looseness
