As a Roots blower blower room, running the noise far exceeded the national standard 《industrial enterprises noise control design specifications》Because of serious noise pollution, the traditional Roots Blower adopt additional muffler, anechoic chamber, and the basis of noise and other noise reduction measures. These measures increase the cost of Roots blower use, even the noise of the Roots blower cost more than the acquisition cost of their own, twisting and clover leaf blower from the noise source Roots begin to change the traditional structure of the Roots blower, passively, Active noise reduction for noise reduction.
Twisted clover leaf clover impeller instead of the traditional impeller, Roots blower to achieve low-noise structural design, to achieve this goal, instead of using helical gears gear. Other parts of the choice of achieving standardization, rationalization and standardization, so that the overall performance of a greater improvement.
Improved after the clover leaf-twisting Roots blower compact, noise, rotor balancing high accuracy, installation standards, economic use for the majority of users with more convenient.
