Rotodynamic Pumps for Vibration Measurement and Allowable Values
This standard applies to rotodynamic pumps and covers the evaluation of vibration when the vibration measurements are made on stationary parts associated with bearings (bearing housings). It provides specific maximum allowable vibration values measured on bearing housings of rotodynamic pumps in field and factory test environments. Topics covered in this standard include bearing housing vibration measurement, speeds above and below 600 rpm, vibration measurement instrumentation, vibration acceptance levels for field and factory tests, acceptance test installation and operating conditions, allowable pump bearing housing vibration, suggested vibration test report, factors affecting vibration, vibration criteria at the top of the motor for vertical pumps.
