Spur gear drive reducer, transmission torque, but the reduction ratio is small, small size, self-locking is not good. The differential gear reducer has a light structure, but its load resistance is weak.
Window ventilation machinery:
Window-opening ventilation machinery refers to a mechanical system that uses electricity or labor in a greenhouse to open and close the roof window or side window of a greenhouse through a special transmission mechanism. Common rack and pinion window openers, crank connecting rod openers, four-link openers, and sash windows are commonly used in the sheds. The rack-and-pinion window opener is now the most commonly used type of window-opening machine. Its core components are racks and racks, and accessory accessories vary with the overall organization. Because of its stable performance, safe and reliable operation, strong bearing capacity, high transmission efficiency, accurate operation and easy realization of automatic control, it is the preferred type of large multi-span greenhouse.
Wet curtain fan cooling system:
Due to the strong solar radiation and greenhouse effect in the summer, the temperature in the greenhouse is as high as 40°C or even above 50°C, resulting in a large number of greenhouses that cannot be planted all year round, especially for perennial seedlings and flowers. The wet curtain fan cooling system uses the principle of converting latent heat into damp heat in the air when water evaporates. The amount of water evaporation is proportional to the air saturation pressure difference. The drier the air, the higher the temperature, the greater the air cooling through the wet curtain. In the hot summer weather, the air is reduced by 4 to 7°C after passing through the wet curtain. The system consists of NB-type wet curtains, 9FJ stealing crabs? (7)?
