Seeking advice on the dynamic balancing of centrifugal compressors
Thread Content
Is it necessary to perform dynamic balancing again on a centrifugal compressor after major repair? If it needs to be done, what kind of program is it? I haven’t come into contact with this before; should we ask a qualified organization to bring their instruments to the site for testing? How much will it cost approximately? Thank you
I’ve heard of performing dynamic balancing on rotors, but this is usually done during replacement or at the time of manufacturing. If the rotor hasn’t been overhauled, it shouldn’t be necessary, right?
After the thorough inspection, balancing the rotor does not require any special instruments; it can be done on a balancing machine. The cost depends on the size of the rotor and whether high-speed balancing is necessary. Once the balancing is completed, the machine generates a report, which helps ensure the proper operation of the equipment.
Dynamic balancing of centrifugal compressors? It’s not the rotor; it’s the balance of the impeller, right?~
If there is vibration, do a dynamic balance. The entire rotor needs to be taken to a qualified facility for high-speed dynamic balancing.
Take a look at the data before maintenance; if the vibration levels are stable and the rotor wasn’t moved during the major repair, then balancing is not necessary. Otherwise, it should be done; the price depends on the size of your rotor, the inspection items and its current condition, as well as the shipping costs back and forth. If you are far away from the dynamic balancing machine, the shipping cost accounts for a large proportion. Typically, the cost of one rotor ranges from 20,000 to 100,000; the exact price will depend on the condition of your rotor.
