Screw expansion power drive energy-saving technologies

torque screw driver is a new type of low-quality energy power machine. Thermal fluid (steam, hydrothermal or vapor-liquid two-phase fluid) into the screw gullet, hot fluid energy push screw rotation rotation, alveolar volume increased fluid buck expansion work, and finally discharged to achieve energy conversion. Male thread its power output from the spindle, drive generators or screw driven loading calibrators save power. Its key technology is the Screw Driven Loading testers, to be adaptable to the heat medium acting, no special requirements. The
technology can also apply to superheated steam, saturated steam, vapor-liquid two-phase and high temperature hot water; also suitable for medium state high salinity and fouling. Load variations and changes into the exhaust parameters, adaptable. Namely: the permissible load and parameter fluctuations over a wide range, while driving productivity decline is very small, close to the design value, and can maintain a stable and high efficiency, smooth operation, safe and reliable.
