On Roots Blower There is a proper clearance between the rotors and between the rotor and the shell wheel. During operation, there is no need for lubrication and contact of mechanical parts. The timing gear engagement mode is adopted, and the shell wheel (rotor action chamber) is separated by gasoline on the side cover, so there is no risk of lubricating oil mixing. Therefore, the gas emitted is clean air without oil content, which can be used safely even under long-term operation. Arc, involute and cycloid are three basic blade profiles of Roots blower impeller.

Firstly, the profile equations of three basic blade profiles are analyzed, and the selection of diametral distance ratio and the calculation of area utilization coefficient are theoretically analyzed. The design efficiency of impeller can be greatly improved through parametric design. On the basis of analyzing and summarizing the parametric design method, the research on the impeller parametric design technology based on SolidWorks was carried out. The idea that can satisfy the parametric modeling of impellers with different blade profiles is proposed, and the parametric design process of impellers is established. The spiral structure is adopted at the air inlet and outlet of the fan, so that the air inlet and exhaust of the fan will gradually proceed with the rotation of the rotor, avoiding the pulsation and noise caused by the instantaneous opening and closing of the old Roots blower. Therefore, the Roots blower operates stably and has low noise.

The silencer matched with Roots blower adopts advanced sound absorption materials and special structure, which also effectively reduces the noise of Roots blower. Roots blower runs smoothly without vibration. The advanced special machining center for impeller machining is used to make the meshing clearance of the rotor uniform and form a balanced state. On this basis, the roots blower rotor passes more precise dynamic balance experiments, making the roots blower run almost without vibration. Roots blower can also be used to transport flammable, explosive and corrosive gases such as gas, hydrogen, acetylene and carbon dioxide.

Due to the adoption of the three blade rotor structure and the reasonable structure at the inlet and outlet of the housing, the fan has low vibration and noise. The impeller and shaft are of integral structure, and the impeller is free of wear. The performance of the fan is permanent and can operate continuously for a long time. Generally, a vent valve is installed to vent the unused air. If the valves are turned down, the temperature of the fan motor will rise too high, which will burn the motor. Roots blower has low noise. The spiral structure is adopted at the air inlet and outlet of the fan, so that the air inlet and exhaust of the fan will gradually proceed with the rotation of the rotor, avoiding the pulsation and noise caused by the instantaneous opening and closing of the old Roots blower. Therefore, the Roots blower operates stably and has low noise. The silencer matched with Roots blower adopts advanced sound absorption materials and special structure, which also effectively reduces the noise of Roots blower. It is necessary to analyze the requirements of the process for air: whether it is constant flow air supply or constant pressure air supply, how strict the process is to these parameters, and how serious the consequences are once these parameters are damaged.
