Mechanical vibration — Measurement and evaluation of machine vibration — Part 8: Reciprocating compressor systems

Mechanical vibration — Measurement and evaluation of machine vibration — Part 8: Reciprocating compressor systems

This document establishes procedures and guidelines for the measurement and classification of mechanical vibration of reciprocating compressor systems. The vibration values are defined primarily to classify the vibration of the compressor system and to avoid fatigue problems with parts in the reciprocating compressor system, i.e. foundation, compressor, dampers, piping and auxiliary equipment mounted on the compressor system. Shaft vibration is not considered. This document applies to reciprocating compressors mounted on rigid foundations with typical rotational speed ratings in the range 120 r/min up to and including 1 800 r/min. The general evaluation criteria which are presented relate to operational measurements. The criteria are also used to ensure that machine vibration does not adversely affect the equipment directly mounted on the machine, e.g. pulsation dampers and the pipe system. NOTE The general guidelines presented in this document can also be applied to reciprocating compressors outside the specified speed range but different evaluation criteria might be appropriate in this case. The machinery driving the reciprocating compressor, however, is evaluated in accordance with the appropriate part of ISO 10816, ISO 20816 or other relevant standards and classification for the intended duty. Drivers are not included in this document. It is recognized that the evaluation criteria might only have limited application when considering the effects of internal machine components, e.g. problems associated with valves, pistons and piston rings might be unlikely to be detected in the measurements. Identification of such problems can require investigative diagnostic techniques which are outside the scope of this document. Examples of reciprocating compressor systems covered by this document are — horizontal, vertical, V-, W- and L-type compressor systems, — constant and variable speed compressors, — compressors driven by electric motors, gas and diesel engines, steam turbines, with or without a gearbox, flexible or rigid coupling, and — dry running and lubricated reciprocating compressors. This document does not apply to hyper compressors. The guidelines are not intended for condition monitoring purposes. Noise is also outside the scope of this document.

Vibrations mécaniques — Mesurage et évaluation des vibrations des machines — Partie 8: Systèmes de compresseurs alternatifs

Le présent document établit des procédures et des lignes directrices pour le mesurage et la classification des vibrations mécaniques des systèmes de compresseurs alternatifs. Les valeurs de vibration sont définies principalement afin de classer les vibrations du système de compresseur et d'éviter les problèmes liés à la fatigue sur les pièces du système de compresseurs alternatifs, à savoir les fondations, le compresseur, les amortisseurs, la tuyauterie et les équipements auxiliaires montés sur le système de compresseur. Le présent document s'applique aux compresseurs alternatifs sur fondations rigides avec des vitesses de rotation nominales supérieures entre 120 tr/min et 1 800 tr/min. Les critères généraux d'évaluation présentés s'appliquent aux mesures opérationnelles. Ces critères servent également à s'assurer que les vibrations de la machine n'ont pas d'effets nuisibles sur les équipements montés directement sur cette machine, comme les dispositifs de suppression des pulsations et la tuyauterie. NOTE Les orientations générales présentées dans le présent document peuvent également être appliqués aux compresseurs alternatifs en dehors de la plage de vitesse spécifiée mais différents critères d'évaluation pourraient être applicables dans ce cas. Les machines d'entraînement du compresseur alternatif sont en revanche évaluées suivant la partie appropriée de l'ISO 20816 ou toute autre norme adéquate et classification pour la fonction prévue. Les pilotes ne sont pas intégrés dans le présent document. Il est admis que les critères d'évaluation pourraient n'avoir qu'une application limitée en ce qui concerne les effets des composants internes des machines; par exemple, il est peu probable que les problèmes liés aux soupapes, pistons et garnitures de piston puissent être détectés lors des mesurages. L'identification de ces problèmes peut nécessiter des techniques de diagnostic d'enquête qui sortent du cadre du présent document. Les systèmes de compresseurs alternatifs couverts par le présent document comprennent, par exemple: — les systèmes de compresseurs horizontaux, verticaux, et de type V, W et L, — les compresseurs à vitesse constante et variable, — les compresseurs à entraînement par moteurs électriques, à gaz et diesel, par turbines à vapeur, avec ou sans multiplicateur, et accouplement flexible ou rigide, et — les compresseurs à fonctionnement avec et sans lubrification. Le présent document ne s'applique pas aux hypercompresseurs. Ces lignes directrices ne sont pas destinées à des fins de surveillance en continu. Le bruit est aussi en dehors du domaine d'application du présent document.

Mechanical vibration — Measurement and evaluation of machine vibration — Part 3: Industrial machinery with a power rating above 15 kW and operating speeds between 120 r/min and 30 000 r/min

This document specifies the general requirements for evaluating the vibration of various coupled industrial machine types with a power above 15 kW and operating speeds between 120 r/min and 30 000 r/min when measurements are made in-situ. Guidelines for applying evaluation criteria are provided for measurements taken on non-rotating and rotating parts under normal operating conditions. The guidelines are presented in terms of both steady running vibration values and in terms of changes to vibration magnitude, which can occur in these steady values. The numerical values presented are intended to serve as guidelines based on worldwide machine experience, but shall be applied with due regard to specific machine features which can cause these values to be inappropriate. In general, the condition of a machine is assessed by consideration of both the shaft vibration and the associated structural vibration, as well as specific frequency components, which do not always relate to the broadband severity values presented. The machine types covered by this document include: a) steam turbines and generators with outputs less than or equal to 40 MW (see Note 1 and Note 2); b) steam turbines and generators with outputs greater than 40 MW which normally operate at speeds other than 1 500 r/min, 1 800 r/min, 3 000 r/min or 3 600 r/min (although generators seldom fall into this category) (see Note 1); c) rotary compressors; d) industrial gas turbines with outputs less than or equal to 3 MW (see Note 2); e) turbofans; f) electric motors of any type, if the coupling is flexible. When a motor is rigidly coupled to a machine type covered by any other part of ISO20816, the motor may be assessed either against that other part or against ISO 20816-3; g) rolls and mills; h) conveyors; i) variable speed couplings; and j) blowers or fans (see Note 3). NOTE 1 Land based steam turbines, gas turbines and generators of greater than 40 MW capacity, which run at 1 500 r/min, 1 800 r/min, 3 000 r/min or 3 600 r/min are covered by the requirements of ISO 20816-2. Generators in hydro-electric plants are covered by ISO 20816-5. NOTE 2 Gas turbines of power greater than 3 MW are covered by ISO 20816-4. NOTE 3 The vibration criteria presented in this document are generally only applicable to fans with power ratings greater than 300 kW or fans which are not flexibly supported. As and when circumstances permit, recommendations for other types of fans, including those of lightweight sheet-metal construction, will be prepared. Until these recommendations are available, classifications can be agreed between the manufacturer and the customer; using results of previous operational experience (see also ISO 14694). Machinery including a geared stage can fall under the scope of this document. For performing acceptance tests of gearboxes please refer to ISO 20816-9. The following types of industrial machine are not covered by this document: k) land-based gas turbines, steam turbines and generators with power outputs greater than 40 MW and speeds of 1 500 r/min, 1 800 r/min, 3 000 r/min or 3 600 r/min (see ISO20816‑2); l) gas turbine sets with power outputs greater than 3 MW (see ISO20816‑4); m) machine sets in hydraulic power generating and pumping plants (see ISO20816‑5); n) reciprocating machines and machines solidly coupled to reciprocating machines (see ISO10816‑6); o) rotordynamic pumps and any integrated or solidly coupled electric motors where the impeller is mounted directly on the motor shaft or is rigidly attached to it (see ISO10816‑7); p) reciprocating compressor systems (see ISO 20816-8); q) rotary positive displacement compressors (e. g. screw compressors); r) submerged motor-pumps; and s) wind turbines (see ISO10816‑21). The requirements of this document apply to in-situ broad-band vibration measurements taken on the shafts, bearings, bearing pedestals, or housings of machines under steady-state operating conditions within their nominal

Mechanical vibration — Vibration of rotating machinery equipped with active magnetic bearings — Part 5: Touch-down bearings

This document gives guidelines for identifying: a) The typical architectures of touch-down bearing systems to show which components are likely to comprise such systems and which functions these components provide; NOTE Touch-down bearings are also known as “backup bearings”, “auxiliary bearings”, “catcher bearings” or “landing bearings”. Within this document, the term “touch-down bearings” is used exclusively as defined in ISO 14839‑1. b) The functional requirements for touch-down bearing systems so that clear performance targets can be set; c) Elements to be considered in the design of the dynamic system such that rotordynamic performance can be optimized, both for touch-down bearings and active magnetic bearings (AMBs); d) The environmental factors that have significant impact on touch-down bearing system performance allowing optimization of overall machine design; e) The AMB operational conditions that can give rise to contact within the touch-down bearing system so that such events can be considered as part of an overall machine design. It also considers failure modes within the AMB system that can give rise to a contact event. This ensures that the specification of the touch-down bearings covers all operational requirements; f) The most commonly encountered touch-down bearing failure modes and typical mechanisms for managing these events; g) Typical elements of a design process for touch-down bearing systems including the specification of load requirements, the sizing process, the analytical and simulation methods employed for design validation; h) The parameters to be taken into account when designing a touch-down bearing system acceptance test programme including the test conditions to be specified and the associated instrumentation to be used to ensure successful test execution; i) The condition monitoring and inspection methods that allow the status of in-service touch-down bearings to be evaluated and when necessary identifying the corrective actions to be taken; j) The factors to be considered when designing the maintenance regime for a touch-down bearing system including the actions to be taken after specified events have occurred together with any actions to be performed on a regular basis; k) The factors to be considered regarding other life cycle topics (e.g. obsolescence management, de-commissioning and disposal).

Mechanical vibration — Torsional vibration of rotating machinery — Part 1: Evaluation of steam and gas turbine generator sets due to electrical excitation

This document provides guidelines for the assessment of torsional natural frequencies and component strength, under normal operating conditions, for the coupled shaft train, including long elastic rotor blades, of steam and gas turbine generator sets. In particular, the guidelines apply to the torsional responses of the coupled shaft train at grid and twice grid frequencies due to electrical excitation of the electrical network to which the turbine generator set is connected. Excitation at other frequencies (e.g. subharmonic frequencies) are not covered in this document. No guidelines are given regarding the torsional vibration response caused by steam excitation or other excitation mechanisms not related to the electrical network. Where the shaft cross sections and couplings do not fulfil the required strength criteria and/or torsional natural frequencies do not conform with defined frequency margins, other actions shall be defined to resolve the problem. The requirements included in this document are applicable to a) steam turbine generator sets connected to the electrical network, and b) gas turbine generator sets connected to the electrical network. Methods currently available for carrying out both analytical assessment and test validation of the shaft train torsional natural frequencies are also described. NOTE Radial (lateral, transverse) and axial vibration of steam and/or gas turbine generator sets is dealt with in ISO 20816-2.

Condition monitoring and diagnostics of machines — Vibration condition monitoring — Part 4: Diagnostic techniques for gas and steam turbines with fluid-film bearings

This document sets out guidelines for the specific procedures to be considered when carrying out vibration diagnostics of various types of gas and steam turbines with fluid-film bearings. This document is intended to be used by condition monitoring practitioners, engineers and technicians and provides a practical step-by-step vibration-based approach to fault diagnosis. In addition, it gives 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 by experienced users, although it is acknowledged that other approaches can exist. Recommended actions for a particular diagnosis depend on individual circumstances, the degree of confidence in the fault diagnosis (e.g. has the same diagnosis been made correctly before for this machine), the experience of the practitioner, the fault type and severity as well as on safety and commercial considerations. It is neither possible nor the aim of this document to recommend actions for all circumstances.

Mechanical vibration — Measurement and evaluation of machine vibration — Part 9: Gear units

This document specifies requirements for determining and classifying mechanical vibration of individually housed, enclosed, speed increasing or speed reducing gear units. It specifies methods for measuring housing and shaft vibrations, and the types of instrumentation, measurement methods and testing procedures for determining vibration magnitudes. Vibration grades for acceptance are included. Torsional vibration measurements are outside the scope of this document. It applies to a gear unit operating within its design speed, load, temperature and lubrication range for acceptance testing at the manufacturer's facility. By agreement between manufacturer and customer and/or operator, it can be used for guidelines for on-site acceptance testing and for routine operational measurements. This document applies to gear units of nominal power rating from 10 kW to 100 MW and nominal rotational speeds between 30 r/min and 12 000 r/min (0,5 Hz to 200 Hz). This document does not apply to special or auxiliary drive trains, such as integrated gear-driven compressors, pumps, turbines, etc., or gear type clutches used on combined-cycle turbo generators and power take-off gears. The evaluation criteria provided in this document can be applied to the vibration of the main input and output bearings of the gearbox and to the vibration of internal shaft bearings. They can have limited application to the evaluation of the condition of those gears. Specialist techniques for evaluating the condition of gears are outside the scope of this document. This document establishes provisions under normal steady-state operating conditions for evaluating the severity of the following in-situ broad-band vibration: a) structural vibration at all main bearing housings or pedestals measured radially (i.e. transverse) to the shaft axis; b) structural vibration at thrust bearing housings measured in the axial direction; c) vibration of rotating shafts radially (i.e. transverse) to the shaft axis at, or close to, the main bearings; d) structural vibration on the gear casing. NOTE Vibration occurring during non-steady-state conditions (when transient changes are taking place), including run up or run down, initial loading and load changes are outside the scope of this document.

Mechanical vibration — Measurement and evaluation of machine vibration — Part 5: Machine sets in hydraulic power generating and pump-storage plants

This document provides guidelines for evaluating the vibration measurements made at the bearings, bearing pedestals or bearing housings and also for evaluating relative shaft vibration measurements made on machine sets in hydraulic power generating and pump-storage plants when the machine is operating within its normal operating range. The normal operating ranges for each type of turbine covered by this document are defined in Annex A. This document is applicable to machine sets in hydraulic power generating plants and in pump-storage plants with typical rotational speeds of 60 r/min to 1 000 r/min fitted with shell or pad (shoe) type oil-lubricated bearings. NOTE The current database includes machine speeds ranging from 60 r/min to 750 r/min (with a very small sample of 1 000 r/min machines). This document defines different limit values of bearing housing and shaft vibration depending on the type of turbine, the orientation of the shaft (i.e. horizontal or vertical) and for each of the bearing locations. This document is based on statistical analysis and provides criteria for the most common types of turbines, pump-turbines and pumps. For specific information on which types of units are covered in this document, see Annex A. Machine sets covered by this document can have the following configurations: a) generators driven by hydraulic turbines; b) motor-generators driven by pump-turbines; c) motor-generators driven by hydraulic turbines and separate pumps; d) pumps driven by electric motors. This document is not applicable to the following unit configurations, parameters and operating conditions: — hydraulic machines with water-lubricated bearings; — hydraulic machines or machine sets having rolling element bearings (for these machines, see IEC 62006 and/or ISO 10816‑3); — pumps in thermal power plants or industrial installations (for these machines, see ISO 10816‑7); — electrical machines operating as motors except for the use of these machines in pump-storage applications; — hydro generators operating as synchronous condensers (with the water in the turbine depressed by compressed air); — assessment of absolute bearing housing vibration displacement; — assessment of axial vibration; — assessment of transient conditions; — non-synchronous operation; — assessment of vibration of the generator stator core or the stator frame level. Measurements made of the bearing housing vibration and shaft vibration occurring in machine sets in hydraulic power generating and pump-storage plants can be used for the following purposes: 1) Purpose A: to prevent damage arising from excessive vibration magnitudes; 2) Purpose B: to monitor changes in vibrational behaviour in order to allow diagnosis and/or prognosis. The criteria are applicable for the vibration produced by the machine set itself. Special investigation is needed for vibration transmitted to the machine set from external sources, e.g. transmitted to the machine via the station foundations.

Mechanical vibration — Measurement and evaluation of machine vibration — Part 4: Gas turbines in excess of 3 MW, with fluid-film bearings

This document is applicable to land-based gas turbines with fluid-film bearings and power outputs greater than 3 MW and an operating speed under load between 3 000 r/min and 30 000 r/min. In some cases (see the list of exclusions below), this includes other rotating machinery coupled either directly or through a gearbox. The evaluation criteria provided in this document are applicable to the vibration of the main input and output bearings of the gearbox but are not applicable to the vibration of the internal gearbox bearings nor to the assessment of the condition of those gears. Specialist techniques required for evaluating the condition of gears are outside the scope of this document. This document is not applicable to the following: i) gas turbines with power outputs greater than 40 MW at rated speeds of 1 500 r/min, 1 800 r/min, 3 000 r/min or 3 600 r/min (see ISO 20816-2); ii) aero-derivative gas turbines (including gas turbines with dynamic properties similar to those of aero-derivatives); NOTE ISO 3977-3 defines aero-derivatives as aircraft propulsion gas generators adapted to drive mechanical, electrical or marine propulsion equipment. Large differences exist between heavy-duty and aero-derivative gas turbines, for example, in casing flexibility, bearing design, rotor-to-stator mass ratio and mounting structure. Different criteria, therefore, apply for these two turbine types. iii) gas turbines with outputs less than or equal to 3 MW (see ISO 7919-3 and ISO 10816-3); iv) turbine driven generators (see ISO 20816-2, ISO 7919-3 and ISO 10816-3); v) turbine driven pumps (see ISO 10816-7); vi) turbine driven rotary compressors (see ISO 7919-3 and ISO 10816-3); vii) the evaluation of gearbox vibration (see this clause) but does not preclude monitoring of gearbox vibration; viii) the evaluation of combustion vibration but does not preclude monitoring of combustion vibration; ix) rolling element bearing vibration. This document establishes provisions for evaluating the severity of the following in-situ broad-band vibrations: a) structural vibration at all main bearing housings or pedestals measured radial (i.e. transverse) to the shaft axis; b) structural vibration at thrust bearing housings measured in the axial direction; c) vibration of rotating shafts radial (i.e. transverse) to the shaft axis at, or close to, the main bearings. These are in terms of the following: - vibration under normal steady-state operating conditions; - vibration during other (non-steady-state) conditions when transient changes are taking place, including run up or run down, initial loading and load changes; - changes in vibration which can occur during normal steady-state operation.

Mechanical vibration — Ground-borne noise and vibration arising from rail systems — Part 31: Guideline on field measurements for the evaluation of human exposure in buildings

ISO/TS 14837-31:2017 gives guidelines to encourage reporting of field measurements of ground-borne noise and vibration in a metric that allows international comparison and future development of empirical models. It also sets out the basic minimum requirements and good practice when taking measurements for the evaluation of human exposure in residential buildings to ensure they are reliable. While national standards or requirements based upon project-specific purposes would normally take priority, this guidance can be used where there are no particular requirements or to provide supplementary guidance. Thereby, this document provides a means of improving general quality and reporting of field measurements in a preferred format. There are a number of reasons for carrying out field measurements of ground-borne noise and vibration arising from rail operations, from complaint investigations to validation of prediction models, diagnostics and research as detailed in ISO 14837‑1:2005, 7.2. In the present document, two levels of evaluation are considered. - Scope 1 corresponds to basic measurements of floor vibration and noise in rooms in buildings to evaluate the human exposure to ground-borne vibration and ground-borne noise. Requirements are presented under two levels of accuracy: basic measurements with minimum accuracy; measurements with reduced uncertainty, also more reproducible and more appropriate for prediction. Ground-borne noise is noise generated by vibrating building elements (e.g. floors, walls and ceilings) in the room of interest and is therefore best expressed by both an acoustic and a vibrational quantity. Its identification as ground-borne noise (as opposed to airborne noise, potentially also present) requires simultaneous noise and vibration measurements. Nevertheless, there are also cases of very low frequency vibration (below 10 Hz to 16 Hz) where only vibration measurements are relevant. Rattle can also arise from vibration, which can be from building components or furniture. This document does not set out to characterize this phenomenon, but to note its presence when it occurs. NOTE In some cases, Scope 1 can relate to measurements on the ground outside a building (to resolve access issues or to comply with national regulations), although measurements at the building are generally preferred. - Scope 2 corresponds to measurements extended to evaluate the vibration immission to buildings, which includes vibration measurements at or near the building foundations and vibration measurements on ground next to the building so that the building coupling loss and building transmissibility can be estimated. Vibration measurements near the tracks (on ground surface or in tunnels) for a proper characterization of the source are outside the scope of this document. Certain requirements are specified in the interest of achieving a consistent minimum data set for each investigation, allowing data comparison between sites.
