Vibration Causes and Solutions for Horizontal Single-suction Cantilever Centrifugal Oil Pump
During the operation of two horizontal cantilever centrifugal pumps,the horizontal vibration on the coupling side exceeded the standard.Through comprehensive analysis of the pump's operating data,support structure,and operating conditions,it was determined that the main causes of the vibration were insufficient support stiffness of the pump,off-design operation,and internal pressure pulsation.To solve this problem,a rigid fixing device was added to the bearing box on the coupling side,successfully eliminating the pump's vibration exceeding the standard.
