标准范围
本文件建立了往复式压缩机系统机械振动测量和分类的程序和指南。振动值主要被定义为对压缩机系统的振动进行分类，并避免在往复式压缩机系统中的部件（即基础、压缩机、阻尼器、管道和安装在压缩机系统上的辅助设备）的疲劳问题。不考虑轴振动。本文件适用于安装在刚性基础上的往复式压缩机，其典型转速额定值范围为120 r/min至1800 r/min（含1800 r/min）。所给出的一般评估标准与运行测量有关。这些标准还用于确保机器振动不会对直接安装在机器上的设备产生不利影响，例如脉动阻尼器和管道系统。注:本文件中给出的一般指南也可适用于规定速度范围以外的往复式压缩机，但在这种情况下，可能适用不同的评估标准。然而，驱动往复式压缩机的机械应根据ISO 10816、ISO 20816或其他相关标准的适当部分或预期用途的分类进行评估。本文档不包括驱动程序。人们认识到，在考虑内部机器部件的影响时，评估标准的应用可能有限，例如，在测量中不太可能检测到与阀门、活塞和活塞环相关的问题。识别此类问题可能需要本文件范围之外的调查性诊断技术。本文件涵盖的往复式压缩机系统示例如下:-水平、垂直、V型、W型和L型压缩机系统，-恒速和变速压缩机，-由电动机、燃气和柴油发动机、汽轮机驱动的压缩机，带或不带齿轮箱、挠性或刚性联轴器，以及-干式运行和润滑的往复式压缩机。本文档不适用于超级压缩机。本指南不用于状态监测目的。噪音也不在本文件的范围内。
This document establishes procedures and guidelines for the measurement and classification of mechanical vibration of reciprocating compressor systems. The vibration values are defined primarily to classify the vibration of the compressor system and to avoid fatigue problems with parts in the reciprocating compressor system, i.e. foundation, compressor, dampers, piping and auxiliary equipment mounted on the compressor system. Shaft vibration is not considered.This document applies to reciprocating compressors mounted on rigid foundations with typical rotational speed ratings in the range 120 r/min up to and including 1 800 r/min. The general evaluation criteria which are presented relate to operational measurements. The criteria are also used to ensure that machine vibration does not adversely affect the equipment directly mounted on the machine, e.g. pulsation dampers and the pipe system.NOTE The general guidelines presented in this document can also be applied to reciprocating compressors outside the specified speed range but different evaluation criteria might be appropriate in this case.The machinery driving the reciprocating compressor, however, is evaluated in accordance with the appropriate part of ISO 10816, ISO 20816 or other relevant standards and classification for the intended duty. Drivers are not included in this document.It is recognized that the evaluation criteria might only have limited application when considering the effects of internal machine components, e.g. problems associated with valves, pistons and piston rings might be unlikely to be detected in the measurements. Identification of such problems can require investigative diagnostic techniques which are outside the scope of this document.Examples of reciprocating compressor systems covered by this document are— horizontal, vertical, V-, W- and L-type compressor systems,— constant and variable speed compressors,— compressors driven by electric motors, gas and diesel engines, steam turbines, with or without a gearbox, flexible or rigid coupling, and— dry running and lubricated reciprocating compressors.This document does not apply to hyper compressors.The guidelines are not intended for condition monitoring purposes. Noise is also outside the scope of this document.
