The number of impeller blades of a Roots blower is generally used to distinguish and name them, just like we commonly say three-blade Roots blower, two-blade Roots blower, etc.

  The number of impeller blades in a Roots blower is generally used to distinguish and name them, such as the commonly referred to three-lobe Roots blower and two-lobe Roots blower. So what are the differences between different impeller quantities? Let's share this with everyone from the Mingfeng manufacturer!

  The three-lobe Roots blower is a positive displacement blower, and the air volume delivered is proportional to the speed. Each rotation of the three-lobe impeller is sucked and discharged three times by two impellers.

The difference between two-lobe and three-lobe Roots blowers

  Compared to two-lobe blower equipment, it has less gas pulsation, lower vibration, and lower noise. The impellers on the two shafts of the blower always maintain a small gap with the inner hole surface of the oval shell, the end face of the impeller, and the front and rear end covers of the blower, as well as between the blower impellers. Driven by the synchronous gear, the airflow is transported from the blower inlet along the inner wall of the shell to the discharge side. This blower chamber does not require lubricating oil, has a simple structure, stable operation, and stable performance, making it suitable for various Applications and widely used in many fields.

  Different models of blower equipment have different usage ranges and application environments. When we are purchasing, we need to pay attention to these situations. Only by understanding these can we buy suitable equipment. I hope everyone can understand the above content!
