Omfattning
This document is applicable to land-based gas turbines with fluid-film bearings and power outputs greater than 3 MW and an operating speed under load between 3 000 r/min and 30 000 r/min. In some cases (see the list of exclusions below), this includes other rotating machinery coupled either directly or through a gearbox. The evaluation criteria provided in this document are applicable to the vibration of the main input and output bearings of the gearbox but are not applicable to the vibration of the internal gearbox bearings nor to the assessment of the condition of those gears. Specialist techniques required for evaluating the condition of gears are outside the scope of this document.


This document is not applicable to the following:


i) gas turbines with power outputs greater than 40 MW at rated speeds of 1 500 r/min, 1 800 r/min, 3 000 r/min or 3 600 r/min (see ISO 20816-2);


ii) aero-derivative gas turbines (including gas turbines with dynamic properties similar to those of aero-derivatives);


NOTE ISO 3977-3 defines aero-derivatives as aircraft propulsion gas generators adapted to drive mechanical, electrical or marine propulsion equipment. Large differences exist between heavy-duty and aero-derivative gas turbines, for example, in casing flexibility, bearing design, rotor-to-stator mass ratio and mounting structure. Different criteria, therefore, apply for these two turbine types.


iii) gas turbines with outputs less than or equal to 3 MW (see ISO 7919-3 and ISO 10816-3);


iv) turbine driven generators (see ISO 20816-2, ISO 7919-3 and ISO 10816-3);


v) turbine driven pumps (see ISO 10816-7);


vi) turbine driven rotary compressors (see ISO 7919-3 and ISO 10816-3);


vii) the evaluation of gearbox vibration (see this clause) but does not preclude monitoring of gearbox vibration;


viii) the evaluation of combustion vibration but does not preclude monitoring of combusti ...
