The material of Roots blower rotor is usually ductile iron or cast steel. These materials have good mechanical properties and wear resistance, which can meet the requirements for the strength and durability of the rotor of the Roots blower during operation.
However, in some special application scenarios, such as transporting corrosive gases or in special environments, stainless steel may be chosen as the material for the rotor. Stainless steel has excellent corrosion resistance, which can ensure the stable operation of Roots blowers under these harsh conditions.
In addition, the material of the shaft of the Roots blower is usually carbon steel or alloy steel, which also has good mechanical properties and wear resistance, and can withstand the axial and radial loads of the Roots blower during operation.
Overall, the material selection of Roots blower rotors needs to be determined based on specific application scenarios and requirements to ensure the performance and stability of the fan.
