How to better cool Roots fans
Roots FansIn the process of using a large amount of heat, so how to better cool the Roots fan? On this issue Roots fan editorial take you to understand.
1. If the fan is installed indoors. Conditioned air conditioners can be installed. Don't worry about air conditioning and electricity bills. Life expectancy is much lower because the motor temperature rises by 10 degrees. Therefore, it is possible to reduce indoor air conditioning, i.e., the life of the equipment, and it is possible to reduce the outlet temperature.
2. In some places, there are noise requirements. If a sound enclosure is installed, the door of the enclosure must be opened in summer. The enclosure creates a limited space, which increases the ambient temperature, which leads to high temperatures in the intake air and high outlet temperatures. Many Roots fans with acoustic enclosures have an inlet temperature of more than 45 degrees in summer.
3. Reduce piping bends, etc. to minimize piping pressure loss and other pressure losses.
4, empirical formula, the outlet temperature of the Roots fan = inlet temperature (10-12) * pressure
The unit of pressure here is the meter column. For example, the water level is 6 meters. The pressure loss in the pipe and the loss in the diaphragm (membrane in the aeration pipe of a wastewater treatment plant) is 1 meter. The ambient temperature is 30 degrees and the outlet temperature is 100-114. degrees. Based on this equation, we can understand the significance of lowering the inlet temperature and outlet pressure.
5. There is also a soil method. Water tanks (especially suitable for aquaculture, sewage treatment, etc.) can be installed at a distance of about 5 to 10 meters from the outlet of the pipeline, which can effectively reduce the temperature of the outlet water.
