YF 70 Industrial Steam Turbine
Summary:
Product Description
The YF70 backpressure steam turbine is a single-stage backpressure turbine. Its rotor features a single-stage velocity-compounding impeller, and the nozzle throat diameter is 1050 mm. The turbine employs an internationally mainstream speed-control system consisting of a Woodward 505 digital controller combined with a CPC electro-hydraulic transducer, multi-valve regulation, and forced lubrication. The main shaft rotates at 3,000 rpm, and a gearbox can be optionally installed according to user requirements to achieve variable-speed operation. The key feature of this model is its use of low-temperature, low-pressure steam with a small pressure differential as the steam source to drive the steam turbine generator and generate electricity, with a maximum generating capacity of up to 3,000 kW.
