适用范围：This part of ISO 10816 gives instructions for the evaluation of vibration on rotodynamic pumps for industrial applications with nominal power above 1 kW. It defines the special requirements for evaluation of vibration when the vibration measurements are made on non-rotating parts (bearing housing vibration). It providesspecific guidance for assessing the severity of vibration measured on bearing housings of rotodynamic pumpsin situ and for the acceptance test at the manufacturer's test facility or in the plant. This part of ISO 10816 alsogives general information and guidelines for assessing relative shaft vibration of the rotating shaft.This part of ISO 10816 specifies zones and limits for the vibration of horizontal and vertical pumps irrespectiveof their support flexibility. The general evaluation criteria are valid for operational monitoring of rotodynamic pumps and for acceptance tests1) in situ or at the manufacturer's test facility if specified. For the acceptance test at the manufacturer's test facility, special conditions are given.For monitoring the vibration values during long-term operation, two criteria are provided for assessing themachine vibration. One criterion considers the magnitude of the observed vibration and the second considerschanges in magnitude. The evaluation criteria are applicable for the vibration produced by the pump itself and not for vibration which is transmitted to the pump from external sources. The criteria mainly serve to ensure a reliable, safe long-term operation of the pump, simultaneously minimizing harmful effects on connecteddevices. Additionally, recommendations are given for defining operational limits and setting alarm and tripvalues.For pump units with integrated electrical motors (impeller directly on the motor shaft or impeller shaft rigidlyconnected to the motor 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. Also, separately mounteddrivers 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.
