ISO 13373-5-2020 pdf free.Condition monitoring and diagnosticsof machines – Vibration conditionmonitoring — Diagnostic techniques for fans andblowers.
This document sets out the specific procedures to be considered when carrying out vibrationdiagnostics of various types of fans and blowvers.
This document is intended to be used by condition monitoring practitioners, engineers and techniciansand provides a practical, step-by-step, vibration-based approach to fault diagnosis. In addition, it gives anumber of examples for a range of machine and component types and their associated fault symptoms.The approach given in this document is based on established good practice,put together byexperienced users, although it is acknowledged that other approaches can exist.Recommended actionsfor a particular diagnosis depend on individual circumstances, the degree of confidence in the faultdiagnosis (e.g.has the same diagnosis been made correctly before for this machine), the experience ofthe practitioner, the fault type and severity as well as on safety and commercial considerations. It isneither possible nor the aim of this document to recommend actions for all circumstances.
The following documents are referred to in the text in such a way that some or all of their contentconstitutes requirements of this document. For dated references, only the edition cited applies. Forundated references, the latest edition of the referenced document(including any amendments) applies.
Machine operational parameter measurements are operational parameters, e.g.rotational speed, load,fan orientation (vertical or horizontal), mounting configuration (solid or flexible support arrangement)and temperatures,that can have an influence on the machine vibration characteristics and aretherefore important to acquire in order to arrive at an appropriate diagnosis.For a given machine, theseparameters can be associated with a range of steady-state and transient operating conditions.
An initial analysis shall be performed in accordance with ISO 13373-3:2015,Annex A. This analysisshould identify safety concerns, the presence of high vibration and, if so, its vibration severity, pasthistory, effects of operating parameters, consequences of not taking corrective actions and the needfor a fan shutdown.Other factors such as mounting configuration, position relative to other rotatingmachines, building structure,environment, etc. should be considered during an initial analysis.See alsoIS0 13373-3:2015,Annexes B to D, for common faults such as from installation and bearing defects.ISO 13373 pdf download.
