Compared with other high-pressure fans, Roots blower is mainly simple in structure, convenient in maintenance, cheap and durable in operation. It is more suitable for small occasions, such as breeding and oxygenation, small sewage treatment plants. Roots blower is good for domestic brands. It is cheap, practical, flexible and widely used. Below 0.8kg, it can replace air pump, and its efficiency is higher than air pump, The effect of aquaculture aeration is better than that of other aeration equipment. Roots blower is also used for sewage treatment aeration, mainly because of its low cost, convenient maintenance and better effect than other fans.
Roots blower consists of impeller and casing. The impeller is embedded on two impeller shafts, one driven shaft and one driving shaft. Each shaft has an impeller, and each impeller has three blades connected, so it is called three blades. The driving shaft and driven shaft rotate and compress by fixing the bearing and engaging the gear. The impeller is processed by a precision CNC planer. The two impellers maintain a certain distance, but they are complementary and colliding. Relatively speaking, there is a certain distance between the impeller and the casing, so as to rotate and compress to produce clean air.
Roots blower is characterized by constant flow, little pressure effect, and the air volume is proportional to the speed, so it belongs to constant volume fan. Small floor area, simple installation, and stable flow without buffer gas tank. The air is free of water and oil and does not need to be filtered again. There is a clearance of 0.2-0.4mm between the impeller and the casing, which is non-contact and can contain a small amount of dust. The performance is stable, which can be used for many years, and the maintenance is simple.
Air cooling is also called air cooling, which means that no other cooling method is required. Under low pressure, the fan can transmit heat through the air and naturally cool down. This type of cooling method is suitable for small Roots fans with low pressure requirements, simple structure and small operating power.
The overall structure of the water-cooled Roots blower is more complex. When the fan pressure is higher than 80kpa, the Roots blower needs to be water-cooled. Because the pressure is too high, the fan temperature will be too high, and long-term operation may cause damage to bearings and gears! Water cooling is to reduce the temperature to extend the service life of the fan.
I believe that after reading the above content, you should also have a better understanding of Roots blower air cooling or water cooling. I hope it will be helpful to you.
