Applications
Tower CSP system
Because there are many tower mirrors, the amount of rotary reducer is the most in tower projects. The tower power station adopts the rotary reducer as the driving component in the horizontal azimuth around the world, and the pitch angle can be selected from the push rod or the rotary reducer. Different thermal power generation EPC manufacturers adopt different structural designs. Since the tower power generation is equipped with many large solar reflectors on a large area of the site, each is equipped with a tracking mechanism, which can accurately reflect the sunlight to the receiver on the top of a high tower. This puts forward higher requirements on the mechanical transmission accuracy, service life, maintenance-free and rigidity of the rotary drive device.
