GB/T 11348.4-2015 in English

《GB/T 11348.4-2015机械振动 在旋转轴上测量评价机器的振动 第4部分：具有滑动轴承的燃气轮机组》由TC53（全国机械振动、冲击与状态监测标准化技术委员会）归口，主管部门为国家标准化管理委员会。
本部分适用于通过齿轮箱相连的其他机器,但不用作对齿轮的振动状态进行评价。对齿轮振动的
评价需要特殊的技术要求,超出了本部分的范围。
本部分规定的这些振动数值并不是评价振动烈度的唯一依据。对于燃气轮机通常也用非旋转部件
上测量的振动值来评价。对这些振动测量的要求见ISO10816-1和 GB/T6075.4。

Scope

This standard applies to heavy-duty gas turbine sets for power generation and mechanical drive with normal operating speed in the range of 3 000 r/min to 30 000 r/min and output greater than 3 MW, with sliding bearings, including gas turbines connected directly or through gears to rotating equipment. This standard does not apply to vibration of the following equipment: a) aircraft-derived gas turbines; b) gas turbines with output less than or equal to 3 MW; c) gas turbine-driven pumps; d) steam turbines and generators with output less than or equal to 50 MAW connected to (or with) gas turbines; e) steam turbines and generators with output greater than 50 MW connected to (or with) gas turbines; f) synchronizing clutches connecting gas turbines to steam turbines or generators; g) driven compressors; h) gearboxes; i) rolling bearings.
