Function and characteristics of Roots blower for special gas transportation

Roots blower for special gas is generally used to transport biogas and pressurize gas. The transported gas does not contain solid medium, special gas other than air at normal temperature. For example, the transportation of methane, nitrogen, gas and other gases.

Generally, when transporting corrosive gases, the overflow materials will be subject to anti-corrosion treatment. The general anti-corrosion processes include nickel phosphorus plating and Teflon coating. Explosion proof motors will be selected for the transportation of flammable and explosive gases.

The delivery of special gas has a variety of sealing options, generally including packing seal, expansion ring seal, mechanical seal and other different sealing forms. The treatment of Roots blower corresponding to different types of gas is also different.

Features of Roots blower for special gas transportation

1. Only the return pipe of the fan is designed. When the air intake flow is insufficient, the fan can form a self circulation without pressure holding on the motor.

2. The sealing form of fan is special sealing, which can effectively limit the leakage of medium.

3. The overcurrent part is generally subject to anti-corrosion treatment.

4. The fan is only suitable for conveying below 60kpa, and more than 60kpa will generally increase the potential leakage.
