Product Description Product DescriptionThe T540 steam turbine is a single - stage back - pressure steam turbine. It is equipped with a velocity-compounded stage impeller, with the impeller pitch - circle diameter being 1040 millimeters. The rotational speed of the main shaft ranges from 1500 to 4500 revolutions per minute, and the power range is from 200 to 2500 KW. A gearbox can be installed as per user requirements to achieve speed variation. The main feature of this model is to utilize steam ranging from low-temperature and low - pressure to sub - high - temperature and sub-high-pressure as the steam source to drive rotating machinery for work, thus realizing the cascade utilization of energy and achieving the goal of energy conservation and consumption reduction.Structural FeaturesStructural form: Quick - installed, double - supported impulse single - stage back - pressure steam turbineArrangement method: Single - layer (can be on the same base as the driven equipment)Mechanical speed control: American Woodward - TG13/TG17Electronic speed control: German Siemens PLC / Japanese Koyo linear actuator / American Woodward - TG17E + 2301Overspeed protection: Two sets of mechanical fly - weight type plus solenoid valve electronic intelligent controlGland seal form: Aluminum - containing carbon - graphite spring - compensated gap - less sealMain steam valve: Integrated automatic main steam valve (quick - closing and regulating combined valve)Main shaft assembly: Velocity - compounded stage impeller blades, the rotor and impeller are assembled with interference fit, and the impeller blades are of inserted - typeLubrication system: Equipped with self - lubricating bearings with oil - slinging ring structureThermal expansion compensation: The front bearing support is of sliding thermal compensation typeDetailed PhotosOverall dimension drawingCross-sectional drawing 1-Cylinder2-Nozzle Group3-Steering Guide Vane Ring4-Steam Seal5-Front Bearing Housing6-Rear Bearing Housing7-Bearing8-Elastic Support9-Valve Seat Frame10-Base11-Main Shaft Assembly12-Impeller13-Valve Assembly14-Emergency Trip Linkage15-Emergency Trip Device16-Regulating Valve Linkage17-Bearing Optimized designProduct ParametersSteam Turbine BodyItemUnitDataProduct Code T540Rated Speed (Gearbox Reduction)r/min3000Number of Turbine Stages 1~3 regulation stagesGovernor Type PLC RegulationOverspeed Protection Method Two-out-of-three electrical overspeed protection + mechanical overspeed protectionOverspeed Protection Actuation Speed Rated speed × (1.09 - 1.11)Overspeed Protection Response Times<0.5Vibration Value at Rated Speedmm≤0.05Vibration Value at Critical Speedmm≤0.15Maximum Axial Displacementmm±0.4Weightt3.4Bearing Lubrication Type Self-lubrication by oil - slinging ringBearing Alarm TemperatureoC65Turbine Dimensions (Length × Width × Height)mm2100×1600×1765Turbine Center Height (from Operating Platform)mm1010Steam Seal Type Comb-Tooth Labyrinth SealNoise LeveldB≤85Unit Continuous Operation Timehr/year8000Auxiliary System ItemUnitDataSeal steam heaterHeat Transfer Aream210Cooling Water Flow Ratet/h15Cooling Water PressureMPa0.2~0.4Cooling Water Temperature (Normal/Maximum)oC27/33Security SystemEmergency Shut-off DeviceThe emergency shut-off device is a protective mechanism that prevents the rotor from exceeding the allowable rotational speed, installed on the main oil pump casing connected to the main shaft. The emergency shut-off device used in this unit is a centrifugal flyweight type, which has an eccentric weight mounted radially on the main oil pump casing. At normal rotational speeds, a spring force balances it. When the unit's speed exceeds the rated speed by 9-11%, the flyweight is thrown out, causing the emergency shut-off throttle to disengage and activate. CertificationsAfter Sales ServiceProvide guidance for equipment installation and commissioning; conduct technical training; during the warranty period, if the unit fails to operate normally or components are damaged due to quality defects, the Seller shall repair them free of charge.Warranty Period: One year.
