Turbine components and systems.
- gearbox: A gearbox is a component used in LT-32 turbines and in the Fabrikam FGT-3200 three-stage gearbox. The LT-32 gearbox has an overall ratio of 1:118.4, a rated input torque of 2,410 kNm, and a dry mass of 21.6 t. Its lubrication system uses splash and forced lubrication, and the total oil volume is…
- gearbox oil heater: gearbox oil heater is an entity of type components in the domain registry, mentioned in 4 source documents.
- generator: The generator is a wind turbine component used with a 690 V double-fed asynchronous generator system. It is driven at 1,500 rpm from the gearbox output shaft, with an overall gearbox ratio of 1:118.4 from a rotor speed of 12.7 rpm. Current records include generator brush inspections and…
- generator brushes: Generator brushes are a component used in Litware LT-32 wind turbines at the Quellmoor Ridge wind farm. Work order WO-26-0436 replaced the generator brushes on WTG-09 under WI-GEN-014 after alarm A3210.
- HSS bearing: The HSS bearing is a gearbox bearing on the generator side, identified in records as part FGT-P-22328. It is linked in the records to high temperature alarms, elevated vibration, wear, and spalling. The bearing is currently below minimum stock, with replacements on order and work orders waiting…
- hydraulic system: hydraulic system is an entity of type components in the domain registry, mentioned in 4 source documents.
- IMS bearing: IMS bearing is an entity of type components in the domain registry, mentioned in 2 source documents.
- oil cooler: An oil cooler is a component that cools oil, using an air/oil cooler with an electric fan and a thermostatic valve that sends oil through the cooler above 45 °C. At Quellmoor Ridge, preventive maintenance for the oil cooler includes radiator cleaning and fan current checks every 6 months. A recent…
- oil cooler fan motor: The oil cooler fan motor is a component identified by part number LWS-P-30418. It is a 1.5 kW critical spare part with stock below the minimum level. For WTG-07, the motor was replaced under WO-26-0398 and the oil cooler radiator was cleaned under WO-26-0399.
- oil filter element: The oil filter element is a component identified by part number FGT-P-11872. It is used in gearbox oil change and oil filter element replacement tasks, including the scheduled MP-GBX-02 task every 12 months. It is replaced during the LT-32 CCV turbine conversion and in response to gearbox oil…
- pitch bearing: Pitch bearing bolt re-torque applies to all variants of LT-32 turbines with M30 10.9 pitch bearing bolts. The task covers 100% of pitch bearing bolts and specifies a torque of 1,450 Nm in the cross pattern of the bolt map, blade by blade. On Quellmoor Ridge Wind Farm, the maintenance plan…
- pitch bearing bolts: Pitch bearing bolts are M30 10.9 bolts used on all variants of LT-32 turbines, with 72 bolts per blade bearing and 216 bolts per turbine. A current bulletin for them requires re-torquing 100% of the bolts to 1,450 Nm in the cross pattern of the bolt map, blade by blade.
- planetary stage: A planetary stage is a gearbox stage with a planet carrier, three planet gears, a ring gear, and a sun pinion. The LT-32 uses a three-stage gearbox with one planetary stage followed by two parallel helical stages.
- rescue kit: A rescue kit is kept in every nacelle and has a sealed kit with a descent device. Its seal must be checked every day, and a broken seal means the kit must be inspected before the next climb. Rescue kit inspections are scheduled every 6 months under MP-HSE-01.
- rotor blade: A rotor blade is a component used in the WTG-04 Blade B replacement job, which is described as a single blade lift. WO-26-0355 is a planned high-priority corrective-maintenance work order for WTG-04 to replace rotor blade B because of a trailing-edge crack.
- service lift: The service lift is a component used on the tower, and climbers should use it when available. In cold weather, it should be used when it works, and its battery should be checked on cold mornings. One service lift stopped twice the previous winter because of cold, and those events should be…
- slip ring: A slip ring is a component that is cleaned with kit LWS-P-55031 and then fitted with new brushes that are checked for free sliding. Its cleaning task MP-GEN-02 is scheduled every 12 months and references WI-GEN-014.
- yaw system: yaw system is an entity of type components in the domain registry, mentioned in 4 source documents.
