Envelope Worm Slew Drive Gearbox With 12V DC Planetary Gear Motor For Solar Tracking System
Description
Fresnel concentrated solar power station, the working principle is similar to trough type photothermal power generation, except that the Fresnel structure condenser is used instead of the mirror. This makes it relatively inexpensive, but the efficiency is correspondingly reduced.
Because such a system has only a few times of concentrating, the quality of the heated water vapor is not high, so that the annual power generation efficiency of the whole system can only reach about 10%; but due to the simple structure of the system and the direct use of heat-transfering medium to generate steam, its construction and maintenance costs are also relatively low.
Features
1. Rotate from 0~180°
2. Connect a driving motor on the left or right side
3. Grease had been filled before factory
4. Simple installation
5. Rational space utilization
6. The gear is self-locking; therefore a brake is not necessary
7. Easy and fluent method of starting and stopping
8. High backholding torque, suitable for vertical installation
9. Low maintenance
