Roots blower is a capacity typeExplosion-proof and anti-corrosion fan, The exhaust air volume of transportation is proportional to the speed. The centrifugal impeller inner hole and the middle of the front and rear bearing end caps of the explosion-proof and anti-corrosion fan and the middle of the centrifugal impeller continue to maintain a fine gap. The mouth spreads along the inner cavity of the casing to the discharged side.
Roots blower andExplosion-proof and anti-corrosion fanThe difference:
1. The principle is different. The centrifugal fan uses a graph fan blade, which throws the steam to the outer shell by centripetal force, while the Roots blower uses two 8-shaped fan blades, and the gap between them is not large. By the extrusion of two leaves, the steam is squeezed to the exhaust port.
2. Because the principles are different, their pressures are usually different. The exhaust working pressure of Roots blowers is relatively high, while centrifugal fans are relatively small.
3. The exhaust air volume is different. Usually Roots blowers are used in areas where the exhaust air volume regulations are not large but the working pressure requirements are high, while the centrifugal fans are used in areas where the working pressure regulations are low and the exhaust air volume regulations are large.
4. The precision of production is different. Roots blower has a high degree of precision, the assembly line is too strict, and the centrifugal fan is loose. Perhaps there are some small differences that I won’t say much.
5. If the load must be the actual effect of constant total flow, use Roots blower. Since the Roots blower belongs to the constant total flow explosion-proof and anti-corrosion blower, the main main parameter in work is the exhaust air volume. The output working pressure changes with the change of the pipeline and load, and the exhaust air volume changes little.
Roots blower is this kind of explosion-proof and anti-corrosion blower. Roots blower is a capacity type explosion-proof and anti-corrosion blower. The exhaust air volume of transportation is proportional to the speed, and the steam is passed from the suction side to the discharge side. If the load must be the actual effect of constant pressure, use a centrifugal fan. Since the centrifugal fan belongs to the constant pressure explosion-proof and anti-corrosion fan, the main main parameter in the work is the air pressure. The output air volume changes with the change of the pipeline and the load, and the air pressure change is not large.
