H415 Industrial Tubine

H415 series turbine is single-stage back pressure turbine. It adopts one double velocity stage at the steam path, with rotate speed 1000-3000 r/min, and output power range 300-3000KW. The regulation system adopts mechanical hydraulic governor, electrical governor or electro-hydraulic regulation system. The intensive forced lubrication (or oil slinger self-lubrication) is implemented at the lubricating station, and the arrangement form is either single-layer or double-layer. 

The prominent advantage of H415 series back pressure turbine is that when it directly connects with the driven equipment, the working rotate speed of which is 1000 r/min or 1500 r/min (usually the rotate speed of turbine is 3000 r/min, and after the speed reduces by gear case to 1500 r/min, the turbine connects with the driven equipment), saving gear case and lubricating station, which decreases customers’ purchase cost and saves space for installation. Simultan eously, as there is no gear case and lubricating station, the operating reliability and safety of the machine set are improved. 

While H415 series back pressure turbine guarantees the above advantage, as the blade pitch circle diameter of turbine is 1300-1400 m, the rim velocity of the pitch circle diameter of turbine is not decreased when the working rotate speed slows down, which maintains internal efficiency of turbine. The economy of 11412 series back pressure turbine is also excellent when it is running under low rotate speed. This series turbine features extensive range of application, especially for working situations where the gear case needs reducing to low rotate speed. 

The working speed of H415 series back pressure turbine can also be 3000 r/min. As the blade pitch circle diameter is big, the internal efficiency can be improved by 8-12% compared with the same type of single-stage turbines.
