Comparative Analysis of Hydraulic Machinery Vibration Evaluation Standards
摘要
Standardization is an inevitable part of technological processes. One of the processes that has been standardized is the evaluation of hydraulic machinery vibrations, which is a key component of machinery reliability assessment. The aim of this paper is to conduct a comparative analysis of the ISO 20816-5 standard and its predecessors, ISO 10816-5 and ISO 7919-5. The main parts and items were grouped into three divisions and compared across the standards. A subjective assessment of the ease and reliability of the new standard’s procedures for these parts and items was conducted. It was concluded that the new standard has significantly simplified and provided a more detailed description of measurement procedures, as well as clearly outlined steps for the reliable evaluation of machinery condition based on vibration measurements and other mechanical parameters.
