GB/T 13824-2015Mechanical vibration of rotating and reciprocating machinery -- Requirements for instruments for measuring vibration severity (English PDF)

Foreword

This standard was drafted in accordance with GB/T 1.1-2009 given rules.

This standard replaces GB/T 13824-1992 "vibration intensity measuring instrument requirements," compared with the GB/T 13824-1992, major repair Changed as follows.

--- Filter is defined as a standard third-order Butterworth filter.

--- Standard covers the frequency range in excess of 10Hz ~ 1000Hz.

And this standard normative international documents cited correspondence between the consistency of the following documents.

--- GB/T 2298-2010 Mechanical vibration, shock and condition monitoring vocabulary (ISO 2041:2009, IDT) this standard uses the translation method identical with ISO 2954:2012 "Mechanical vibration of rotating and reciprocating machinery vibration intensity measuring instrument Requirements "(in English).

For ease of use, this standard made the following editorial changes.

--- The original text of the "2sigma expanded uncertainty" with "expanded uncertainty (k = 2)" instead.

This standard by the national mechanical vibration, shock and condition monitoring Standardization Technical Committee (SAC/TC53) and focal points.

This standard was drafted. Shanghai Measurement and Testing Technology Research Institute, Jiangsu Donghua Testing Technology Co., Ltd., the state-owned plant four thousand three hundred and eighty Jiaxing Branch, Shaanxi Province Institute of Metrology, Beijing Institute of Metrology detection.

1 Scope

This standard specifies the machine housing, especially given the uncertainty of the machine to monitor trends made repeated measurements does not exceed the predetermined value, Vibration intensity measuring instrument shall meet the requirements.

This standard applies to direct display or recording unit of measure is defined as the rms vibration velocity (rms) of the instrument.

Note 1. Appendix A gives the True RMS method to check the display to retain this approach is mainly aimed not based on modern analog to digital conversion and RMS values \u200b\u200bcount Operators instruments, but the method is also applicable based on this instrument.

Note 2. In the specified frequency range, these instruments can also be used for other occasions, similar to the measurement accuracy of such structures, tunnels, bridges and other vibration speed Measuring degree may also include phase measurement options.

4 Measurement parameters

Table 1 shows the measured parameter non-rotating member of mechanical vibrations to describe.

Measurement parameters for broadband and discrete frequency components of the signal can be integral and differential conversion (see GB/T 6075.1-2012 Appendix A).

Measured maximum vibration amplitude is called vibration intensity. The vibration intensity can be given intensity level (see GB/T 6075.6-

2012 Table 1).

Note. Previously, vibration intensity usually only refers 10Hz ~ 1000Hz bandwidth rms vibration velocity. This standard provides for having such restrictions Equipment requirements, but also allows the use in other frequency ranges.

Measuring instrument should be able to measure the parameters given in Table 1, or at least be able to measure the vibration velocity in the frequency range 5.3 are defined Square root.

If the measurement filter obtained from the magnitude of the discrete frequency points wideband bandpass filter should have the appropriate bandwidth. You can also
