Vibration problem at the outlet of cam rotor pumps
Thread Content
The outlet pipeline of the cam rotor pump experiences significant vibration (the pump outlet is equipped with flexible connections, which deform considerably during vibration), while the pump body vibrates normally. How can this vibration problem be resolved?
These types of problems are quite complex. First, it is necessary to determine whether it is an innate problem or an acquired one. If it is a problem related to the future, the inspection should start at the point where the pump is fixed to its foundation, such as the installation of gaskets after maintenance and the tightness of the bolts. A thorough inspection is required to check for any looseness in the supports, gaskets, and clamps related to the pipes. For reference.
Support brackets are added to the outlet rigid pipe, and clamps are installed to change the resonance frequency.
Reduce the outlet pressure; the rotor pump has a cantilever structure, and high outlet pressure inevitably leads to significant vibration.
