Roots blower is a kind of compression machine formed by two identical rotors. The axes of the rotors are parallel to each other. There is a small gap between the impeller and the impeller, between the impeller and the casing, and between the impeller and the wallboard in the rotor to avoid mutual contact. The intake chamber and the exhaust chamber are isolated from each other. With the help of the reverse rotation of the two rotors, the gas in the body is sent from the intake chamber to the exhaust chamber to achieve the role of blowing. Since there is a small gap between the impellers, between the impellers and the casing, between the impellers and the wallboard, there is no need to inject lubricating oil into the cylinder or auxiliary equipment of the oil-gas separator during operation. Since there is no mechanical friction between rotors, it has the advantages of high mechanical efficiency, less overall heating and long service life. Roots blower is a relatively sophisticated equipment. During normal maintenance, attention should be paid to the cleaning and replacement of inlet filter, the cleanness and smoothness of indoor air, and the lubrication should be guaranteed.
Roots blower is a positive displacement blower. The air volume increases or decreases with the increase or decrease of speed, and the air pressure is related to the current. That is, the flow is less affected by back pressure. The return valve makes use of the characteristics of Roots blower to realize the constant flow regulation of loose air. During operation, pay attention that the exhaust pressure of the fan shall be below the value on the label to avoid damaging its internal pressure parts.
