Applications
Application of Rotary Drive in Photothermal Tracking System
1. Dish tracking system, two-axis tracking can actually be divided into two types: horizontal and elevation.
2. The trough type photothermal system can be divided into large trough type and small trough type. Due to the large opening of the groove and the requirement of fast rotation speed, hydraulic cylinders are currently used more for large grooves, but there are also large groove projects using reducers. For small trough type, mainly heating trough type projects, the length of the collector is relatively short, which is very suitable for the installation and use of the VE series vertical rotary reducer. Due to the integrated design of the support and the rotary reducer, the installation is convenient. At the same time, the complex structural design of the trough bracket is simplified.
3. The Fresnel project is similar to the mini-trough.
