Feed Water Pump Turbine
The self-developed Feed Water Pump Turbine is the variable speed condensing turbine specially designed for driving high pressure boiler water supply pump of 200-660MW unit. It has created a series of TGQ turbines which have 6 models and 12 specifications, such as 6MW, 7MW, 8MW, 9MW, 10MW and 12MW. In the operation achievement of almost 400 turbines at home, it has a high occupancy and receives good feedback from users.

● Technology Feature
The design of the single-cylinder, impulsion, double vapor sources, variable speed and condensing turbines has the features of light-weight body, small axial thrust, good adaptability for rapid change of load, and less leaking of blade tip and shaft seal and so on. At the same time, it adopts the internal switching mode of vapor sources and spray head vapor distribution system which make the operation more reliable and make the vapor sources switching steadier without perturbation motion.
●Scope of Application
It is used for driving the high-pressure boiler water feed pump of 200-660MW unit.
