This Part replaces GB/T 6075.1-1999 "Measurement and Evaluation of the machine on the non-rotating member of the mechanical vibration - Part 1. General then". This section compared with the GB/T 6075.1-1999, the main modifications are as follows.

--- Modify the standard name from the original "Measurement and evaluation of the machine on a non-rotating member of the mechanical vibration - Part 1. General" change as "mechanical vibration evaluation machine vibration measurement - Part 1 on a non-rotating parts. General";

--- Modify the previous edition of "vibration amplitude" in many translations, unified to "vibration values";

--- Original standard "provisional value of the area boundary is given in Appendix B." Changed to "no clear classification for the type of machine Mitsuke Record B. "(See 5.3.1);

--- Original criteria in Appendix B "provisional unit dedicated broadband vibration criteria" to "set area boundary values \u200b\u200binformative guide." increase

Introduction

GB/T 6075 is the basis for this part of the technical documentation. It provides a non-rotating (or reciprocating) machine components such as bearing motivated when the line of measurement, the measurement and evaluation of machine vibration General. For specific types of machines recommended measurement and evaluation criteria, in GB/T 6075 the other part is given.

For many machines on the non-rotating parts measure is sufficient to describe the health of trouble-free work. But for the like comprising flexible rotor Some machines are not very appropriate measure only on non-rotating parts. In this case, it is necessary in the rotating and non-rotation of two parts Measurements or measurements on rotating parts only to monitor the machine. For such machines, this section expressed by the general provisions given in ISO 7919-1 General to supplement shaft vibration. If the two standard methods can be used, it should generally use a more restrictive.

Vibration measurements can be used for a variety of purposes, including routine operational monitoring, acceptance testing, diagnosis and analysis. This section provides only about transport General line monitoring and acceptance testing.

This section provides three basic measurement parameters (displacement, velocity, acceleration), and gives their limits. In accordance with the Appendix to this section Guidelines, in most cases, be able to ensure that the machines operate satisfactorily.

Measurement and evaluation of mechanical vibration on non-rotating member Machine vibration - Part 1. General

1 Scope

GB/T 6075 This section provides the measurement and evaluation of machine vibration on non-rotating or reciprocating machine parts and Party General Conditions law. The magnitude of vibration and the vibration change both expressed operation monitoring and evaluation criteria and acceptance tests related. First proposed evaluation criteria Consider first the machine safe and reliable long-term operation, taking into account the harmful effects of the related equipment is minimized. This section also provides the operational Limit.

Evaluation criteria in this section only with the vibration generated by the machine itself, but not with an external vibration passed to it has nothing to do.

This section does not consider the torsional vibration.
