YDB670-900 Series Hydraulic Torque Converter with Adjustable Guide Blades
YDB670-900 series hydraulic torque converter with adjustable guide blades is a newly integrated hydraulic transmission product with optimized design of CNPC Jinan Diesel Engine General Factory, in light of adjustable speed transmission condition of compressor in domestic petrochemical industry, by fully learning from and drawing on characteristic technical structure of similar international well-known companies, based on technical achievements for about ten years in the field of domestic hydraulic transmission engineering technology. It is mainly applicable to transmission of dual plunger compressor, pump and oil rig. This series of products fills the gap at home and has frontier technology in China currently.
This series of products adopts the speed regulation technology form of guide blade rotation, changes the circulating flow by adjusting opening adjustable blades and changing established angle of blade profile, circulation of blade grid outlet, inlet attack angle and the flow area, thus changes the capacity of torque converter, finally realizes the output speed adjustment. Various types of intelligent electric actuators can be selected in accordance with specific process requirements, and automatic closed loop adjusting and controlling can be realized to achieve a more perfect effect of operating condition matching.
Main technical parameters:
Rated input rotating speed: 1,000 ~ 3,000 r/min
Rated input power: 475 kW ~ 3,000 kW
Ratio of transmission under rated operating condition: 0.92
Rated efficiency: ≥85%
Speed regulating range: 30% ~ 100%
Speed regulating form: automatic closed-loop control of intelligent multi-turn electric actuator
