服务中心振动分析

服务中心盖的振动分析This 48-page manual was developed following EASA’s 12-part 服务中心的振动 系列讲座. It serves as an introductory training resource for service center technicians and supervisors involved in measuring, 评估, and correcting vibration and balancing issues on machines under repair – as opposed to the in-plant predictive maintenance tasks covered in most general classes on the subject.

This document is intended as basic introductory training material for anyone who may be involved in 评估 or correcting vibration issues on machines repaired in the service center. Only certain sections may be of interest depending on the area and amount of involvement in vibration issues.

买这本书

For a technician with responsibility for analyzing and correcting vibration and balancing issues, a general understanding of all of the information is essential. For technicians who will conduct field vibration and balancing services in customers' facilities, 强烈建议进行额外的培训. A Level 1 vibration analysis class (usually 4 or 5 days) is a first step toward the competence needed for conducting field services. 建议参加2级课程. A number of providers offer ANSI-certified Level 1 and Level 2 vibration analysis classes, which normally include an opportunity for certification.

配套的12部分网络研讨会录音系列

This 12-part recording (15 hours) covers a wide range of topics on vibration.

Members rely on EASA to provide technical assistance and training in all areas related to machinery repair. 在机械振动领域, there are training providers that offer general classes in vibration analysis and balancing, but the content is geared to plant maintenance personnel who would be conducting in-plant predictive maintenance services. Some key areas important to EASA service center technicians is not covered adequately, and much of the content does not apply to vibration testing conducted in the service center. This course is designed to address those shortcomings and provide fundamental training in vibration analysis and balancing that directly applies to technicians working in the service center.

本系列的主要目标

本系列网络研讨会旨在:

  • Provide EASA service center technicians with the technical knowledge they need to effectively measure and diagnose vibration on machines being tested in the service center.
  • Provide the foundation understanding necessary to use vibration data as an indicator of machinery condition
  • Provide the fundamental knowledge of dynamic balancing necessary to use common balancing instruments in the service center

谁会从观看这个系列中受益?

Service center technicians who measure and analyze machinery vibration, and those who must evaluate the vibration data will benefit greatly from the fundamental understanding and knowledge provided by this training series. Service center engineers who may be involved in writing, interpreting and applying vibration and balancing specifications and tolerances will gain a practical understanding of the terms, definitions and parameters encountered in those specifications.

和任何技术课题一样, fundamental math skills will allow attendees to quickly comprehend concepts and apply techniques. Vibration results from the mechanical and electrical forces at work in machinery, and a fundamental understanding of those forces, 以及导致这些问题的机器部件, will aid in the understanding and application of the subject matter.
