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.
