Спасибо! Здесь имеется в виду проверка турбогенератора: Major Inspection
Major Inspection is a package of complex maintenance activities, which are considered necessary for returning the equipment close to its original state.
The main target of Major Inspection is to ensure trouble-free operation of the TG equipment during the next maintenance cycle (thorough inspection of the actual state of all equipment and accessories – especially internals, change out of worn parts, and replenishment of spare parts)
The typical scope of the Intermediate Inspection includes besides the scope of Minor Inspection also:
- Opening the turbine casings
- Check of radial and axial tolerances
- Cleaning of turbine steam flow path to ensure machine efficiency and reliability, cleaning and flushing of lubrication oil & hydraulic oil systems, cleaning of condenser & heaters
- Re-setting of clearances and the mechanical items within the control system
- Repair of imperfections which may have been found during operation or subsequent inspection
- Execution of maintenance tasks which take longer than one week
- Check of exciter and generator
During a Major Inspection, all the equipment and accessories should be opened to permit inspection of the internals, NDT inspection (where necessary) and large-scale diagnostic measurements.
The scope of Major Inspection may vary each 6 years according to operating conditions and operation hours. The TG that is 12 years in operation requires other care and scope of spare parts than TG that is 6 years in operation.
