Roots blower product features

Roots blower, also called Roots blower, is a volumetric rotary blower that uses two or three blade-shaped rotors to move relative to each other in the cylinder to compress and transport gas. This type of blower has a simple structure and is easy to manufacture. It is suitable for gas transportation and pressurization in low-pressure situations, and can also be used as a vacuum pump.
Its biggest feature is that when the pressure is adjusted within the allowable range, the flow rate changes very little, the pressure selection range is wide, and it has the characteristics of forced gas transmission. The medium does not contain oil during transportation. It has simple structure, easy maintenance, long service life and small vibration of the whole machine.

Vacuum pump. Due to the pulsation of air flow velocity and pressure caused by periodic suction and exhaust and instantaneous isovolumetric compression, large aerodynamic noise will be generated. In addition, the gaps between the rotors and between the rotors and the cylinder can cause gas leakage, thus reducing efficiency. The exhaust volume of Roots blower is 0.15~150 cubic meters/min, and the rotation speed is 150~3000 rpm. The single-stage pressure ratio is usually less than 1.7 and can be as high as 2.1, and multiple stages can be used in series.
