The 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.
