Vibration measurement during the individual trial operation of a centrifugal pump
Thread Content
After the centrifugal pump has been installed, vibration levels need to be measured during its individual trial operation. According to page 71 of GB50275-2010, the allowable limit for the effective value of the pump’s vibration velocity is specified (the unit of measurement is mm/s)； On page 32 of SH3538-2005: regarding the vibration values at the centrifugal mechanical bearings (with the measurement unit in mm), which of these two values better reflects the reliability of a newly installed device and gives a better indication of the quality of its installation? These two types of measurements
What is the principle behind these two types of measurements?； Can the measurement units be converted?
Low-frequency vibration: 60,000 revolutions per minute), with acceleration in mm/(s^2) as the vibration standard.
Vibration of general pumps is evaluated using velocity values!
There are specific standards for pump vibration, which specify the selection of measurement points and the vibration limits.
