BAIJIAN - Third party testing organization
This standard specifies the evaluation requirements for the performance and characteristics of balancing machines used for balancing rotating components. This standard focuses on the format of balancing machine characteristics that should be developed by the manufacturer、 and outlines the evaluation criteria and test methods for weighing machines. It is recommended to use the formats specified in 4.1 and 4.2 to facilitate users' comparison of products from different manufacturers. Appendix B provides guidance for users to express their requirements. This standard details the methods used to verify the rotor、 test quality、 and performance detection to ensure consistency with the imbalance indication capacity specified by the balancing machine. This standard does not specify the testing of other capabilities and performance parameters of the balancing machine. Appendix E describes the recommended modification plan for the old calibration rotors specified in the original national standards GB/T 4201-1984 and GB/T 7662-1987. This standard does not specify a balance criterion、 which is specified in GB/T 9239.1-206. This standard is applicable to balancing machines that support and rotate the workpiece in a constant state (rigid) at a balanced speed. The balancing machine can indicate the magnitude and phase angle that require imbalance correction on one or more planes. This standard includes two types of balancing machines for measuring imbalance effects on soft and hard supports. This standard also includes technical requirements for the above-mentioned balancing machines、 but does not include special performance related to automatic calibration. 2 Normative reference documents. The following documents contain references to Tiaomin liquor that have been cited in this standard and become the articles of this standard. Any subsequent modifications (excluding errors) or revisions do not apply to this standard. However、 All parties who have reached an agreement based on this standard will investigate whether new versions of these documents can be used. For undated references、 the latest version of * applies to this standard GB/T 6444 Mechanical Vibration Balancing Terminology (GB/T 6444 1995、 eqv ISO 1925:1990) 3 Terms and Definitions The terms and definitions established in GB/T 6444 are applicable to this standard. For ease of use、 Appendix A lists some terms and definitions related to balancing machines in GB/T 6444. The manufacturer of the capacity and performance data of the balancing machine should use a similar format as specified in 4.1 or 4.2. Provide data suitable for horizontal or vertical balancing machines. 4.1 Horizontal balancing machine data. 4.1.1 Rotor mass and unbalance limit. 4.1.1.1 The maximum mass of the rotor that the balancing machine can balance within the entire range of balancing speeds should be indicated. The corresponding balance speed (n、 period...) should be given、 and the corresponding period rate (see Table 1) should be given along with the large moment of inertia (mass * multiplied by the square of the turning radius) of the rotor that the balancing machine can complete acceleration within the specified acceleration time
