Product Description Product DescriptionThe T380 steam turbine is a multi-stage back-pressure steam turbine with a single-layer arrangement, featuring compact size and convenient installation. The main shaft operates at a rotational speed of 8,000 r/min, extendable up to 12,000 r/min. Its rotor employs an integrally forged design, and the flow passage consists of one regulating stage and four pressure stages. Axial steam seals between stages minimize steam leakage losses. The main steam valve operates automatically, controlled by high-pressure oil for opening and closing.This turbine offers a power range of 200-2,000 kW and demonstrates broad applicability. Particularly in petrochemical applications, it drives high-speed direct-drive compressors, water pumps, and fans without requiring gearboxes. This configuration reduces potential failure points, lowers enterprise costs, and delivers low operational expenses for high-speed equipment with notable economic benefits.Detailed PhotosOverall dimension drawingCross-sectional drawing1 - Base Frame2 - Front Pedestal3 - Front Bearing Housing4 - Emergency Trip Mechanism5 - Front Combined Journal-Thrust Bearing6 - Hydraulic Control Block Assembly7 - Control Valves and Linkage8 - Front Steam Seal9 - Nozzle Group/Nozzle Assembly10 - 1st Stage Diaphragm11 - 2nd Stage Diaphragm12 - 3rd Stage Diaphragm13 - 4th Stage Diaphragm14 - Upper Half Casing15 - Rear Steam Seal16 - Lower Half Casing17 - Rear Bearing18 - Rear Bearing Housing19 - RotorProcess FlowOptimized designProduct ParametersSteam Turbine BodyItemUnitDataProduct Code T380Rated Speed (Gearbox Reduction)r/min7000~12000Number of Turbine Stages 1 regulation stage + 4 pressure stagesGovernor Type DEH Electro-Hydraulic 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±0.4Weightt3Bearing Lubrication Type Forced lubricationBearing Alarm TemperatureoC85Turbine Dimensions (Length × Width × Height)mm3300×1600×2000Turbine Center Height (from Operating Platform)mm900Steam Seal Type Comb-Tooth Labyrinth SealNoise LeveldB≤80Unit Continuous Operation Timehr/year8000Turning Gear Method Electric Turning GearAuxiliary SystemItemUnitDataOil StationFlow rateL/min300Oil 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.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.
