High Accuracy SDE7 Worm Gear Slew Drive For Concentrated Solar Power Tower
High Accuracy SDE7 Description
The dual axis slew drive could be applied in concentrated solar power station-tower. The Tower CSP adopts the double tank structure, and the binary nitrate is used as the heat absorbing and heat storage medium. The solar energy collected by the large-scale heliostat field is used to store the molten salt, and then the molten salt is exchanged with the water according to the dispatching instruction of the power grid. The generated high temperature and high pressure steam drives the turbine generator set to generate continuous, stable and schedulable power output.
Hangtuo‘s slewing drive is composed of the housing, slewing bearing, sealing, enveloping worm with some completed spare parts. We can also produce the Electronic motor and Hydraulic motor used for slewing drives, which can moves for clockwise direction and counter clockwise direction rotation.
