Vibration will exist in all pumps and indeed all rotating machines. These pumps and other rotating machines produce vibrations in horizontal and vertical planes and also exert centrifugal and torsional vibrations. All these vibrations are avoidable by designing proper Anti-Vibration Mounts for mounting these pumps and other rotating machinery. Pump designers (and motor designers) design machines to withstand normal vibration limits. These vibration isolation limits vary by pump type, mounting configuration, power requirements, rotative speed and fluid being pumped. Even these vibration limits are sometimes very high considering the other machinery to be placed in the vicinity and thus Anti-Vibration Mounts are required for mounting these pumps. Excessive vibration in pumps may lead to excessive noise, equipment damage, and premature pump failure due to fatigue.
Main causes of Pump Vibration:
★ Misapplication, design, or manufacturing defect causing vibrations in Pumps.
★ Corrosion and erosion – Damage from corrosion or erosion…
