Mechanical vibration - Evaluation of machine vibration by measurements on non-rotating parts - Part 7: Rotodynamic pumps for industrial applications, including measurements on rotating shafts (ISO 10816-7:2009)
This part of ISO 10816 describes the special requirements for evaluation of vibration when the vibration measurements are made on non-rotating parts (bearing housing vibration) of rotodynamic pumps for industrial applications with nominal power above 1 kW. It provides specific guidance for assessing the severity of vibration measured on bearings of rotodynamic pumps in situ and for the acceptance test at the manufacturer's test facility or in the plant. It also gives general information for assessing relative shaft vibration. For pump units with integrated electrical motor (impeller directly on the motor shaft or impeller shaft rigidly connected to themotor shaft), this part of ISO 10816 applies to the whole coupled unit. For flexibly coupled motors, this part of ISO 10816 is applicable for the pump only. This part of ISO 10816 takes precedence on all details of ISO 10816-3 which deal with vibration of pumps. However, separately mounted drivers are not within the scope of this part of ISO 10816. Those drivers are dealt with in ISO 10816 3. The following types of pumps are excluded from this part of ISO 10816: - reciprocating and rotating positive displacement pumps, - reciprocating engine driven pumps, - pumps in hydraulic power generating and pumping plants with power above 1 MW (see ISO 7919-5 and ISO 10816-5), - solids handling, slurry and submersible pumps. Torsional vibration is not dealt with in this part of ISO 10816.
