As the weather temperature gradually rises, cooling has become the primary problem, so how should the Roots blower cool down?Roots BlowerI'll take you through it.
1, the fan if installed indoors. Conditional can be installed air conditioning. Do not pity air conditioning and electricity costs. Because the motor temperature rises every 10 degrees, life expectancy is reduced a lot. So indoor air conditioning, that can extend the life of the equipment, but also can reduce the exit temperature.
2, some places have noise requirements, equipped with soundproof enclosure, in the summer must open the door of the soundproof enclosure. Soundproof enclosure to form a confined space, increasing the ambient temperature, resulting in the inhalation of air temperature is high, the export temperature is also very high. Many Roots fans with soundproof enclosures have an inlet temperature of more than 45 degrees in the summer.
3. Reduce the bends of the pipeline, etc., to minimize the pipeline pressure loss and other pressure losses.
4, empirical formula, the outlet temperature of the Roots blower = inlet temperature + (10-12) * pressure
The unit of pressure here is meter water column, for example, the water level is 6 meters, the pressure loss of pipeline loss and diaphragm loss (wastewater plant aeration pipe diaphragm) is 1 meter, the ambient temperature is 30 degrees, then the outlet temperature will be 100-114 degrees. Based on this formula we can understand the significance of reducing the inlet temperature and outlet pressure.
5, there is a stupid method, in the distance from the pipeline outlet about 5 ~ 10 meters to install a water tank (especially suitable for aquaculture, sewage treatment, etc. Blast aeration), can effectively reduce the export temperature.
