Will the parameters be affected after the Roots blower is connected in series?
Release time:
2022-04-24
When multiple Roots blowers work together, series connection mainly increases pressure, while parallel connection mainly increases flow. However, the performance of Roots blowers when working together is not simply additive. Generally, when in parallel, Roots blowers will use equipment of the same model and performance parameters. If equipment of different models and different speeds are connected in parallel, the situation is similar to the above, but at this time, the equipment with lower performance may output very little air volume or even fail to deliver air when the total flow decreases. Therefore, connecting blowers of different models and parameters in parallel is more complex and is generally less common. The series connection of Roots blower equipment refers to adding another blower device at the intake of the main blower. This increases the air density at the intake of the main blower, increasing the air mass per unit volume, which raises the compression ratio, hence series connection can increase pressure. If blowers with different performance parameters are connected in series, the situation is even more complex, influenced by the pipeline characteristic curve as well as the blower equipment parameters and their positions. Pressure will only be increased under specific conditions; otherwise, it may have the opposite effect.
