标准范围

ISO 10816-4:20 09制定了评估所有主轴承座或底座上径向（即横向）轴轴线以及推力轴承上轴向测量的现场宽带振动严重程度的具体规定。这些是:-正常稳态操作条件下的振动；-当瞬时变化正在发生时的其他(非稳态)条件下的振动，包括运行上升或运行下降、初始负载和负载变化；-在正常稳态操作期间可能发生的振动变化。ISO 10816-4:20 09适用于用于电气和机械驱动应用的重型燃气轮机组，带有液膜轴承，输出功率大于3 MW，负载下的运行速度范围在3 000 r/min和30 000 r/min之间。

ISO 10816-4:2009 establishes specific provisions for evaluating the severity of in-situ, broad-band vibration measured radial (i.e. transverse) to the shaft axis on all main bearing housings or pedestals and in the axial direction on thrust bearings. These are in terms of:- vibration under normal steady-state operating conditions;- vibration during other (non-steady-state) conditions when transient changes are taking place, including run up or run down, initial loading and load changes;- changes in vibration which can occur during normal steady-state operation.ISO 10816-4:2009 is applicable to heavy-duty gas turbine sets used in electrical and mechanical drive applications, with fluid-film bearings, outputs greater than 3 MW and an operating speed range under load between 3 000 r/min and 30 000 r/min.
