Product Description Product DescriptionThe T530 steam turbine is a single - stage back - pressure steam turbine. It has a velocity - compounded stage impeller with an impeller pitch circle diameter of 800 millimeters. The rated speed of the main shaft is 3000 revolutions per minute, and the power range is 300 - 1500 kW. A gearbox can be installed according to user requirements to achieve speed change. The main feature of this model is to use superheated steam as the steam source to drive rotating machinery to do work, realizing the cascade utilization of energy to achieve the purpose of energy conservation and consumption reduction.Detailed PhotosOverall dimension drawingCross-sectional drawing 1-Chassis 2-Elastic Bracket 3-Front Bearing Housing 4-Speed Sensor 5-Emergency Trip Device 6-Emergency Trip Device Linkage 7-Support Thrust Front Bearing 8-Thermal Resistor 9-Rotor 10-Steam Seal 11-Cylinder 12-Impeller Blade 13-Rear Bearing Housing 14-Rear Bearing 15-Coupling Optimized designProduct ParametersSteam Turbine BodyItemUnitDataProduct Code T530Rated Speed (Gearbox Reduction)r/min3000Number of Turbine Stages 1 regulation stageGovernor 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≤0.03Vibration Value at Critical Speedmm≤0.15Maximum Axial Displacementmm±0.4Weightt3.1Bearing Lubrication Type Forced lubricationBearing Alarm TemperatureoC85Turbine Dimensions (Length × Width × Height)mm1900×1450×1540Turbine Center Height (from Operating Platform)mm960Steam Seal Type Comb-Tooth Labyrinth SealNoise LeveldB≤85Unit Continuous Operation Timehr/year8000Auxiliary SystemItemUnitDataOil StationFlow rateL/min63~125Oil Pump Configuration Oil pressure: Adjustable from 0.3 to 1.0 MPaTwo AC oil pumps, one DC oil pumpSeal steam heaterHeat Transfer Aream215Cooling Water Flow Ratet/h35Cooling Water PressureMPa0.2~0.4Cooling Water Temperature (Normal/Maximum)oC27/33 Security 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. Certifications After 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.
