Roots blowers can be roughly divided according to their different ways of working with a single-stage two-stage of the points, only one compression stage blower Roots blower, which we call the large single stage blower Roots blower, and the two single-stage Blower series, on two successive compressed gas that we call the two-stage blower fan. Divided by Transmission: direct connection with fans and blowers Union; divided by Cooling: air cooling fans, blowers and water-cooled counterflow cooling blowers; by structure type: Vertical blowers, blower horizontal, vertical shaft blowers, densely into blowers and other groups; press seal type points: labyrinth seals, piston ring seals, packing and mechanical seals and other various types of blowers. We all know the power blower, a major role is the muffler muffler, muffler used in the machinery can serve to reduce the effects of noise. Similarly, the use of the blower also has a good effect. So the amount of wind blower, blower imported muffler what good is it? First, import muffler is the use of resistive muffler, mainly imported blower airflow to eliminate noise from the outer tube, inner tube, flanges and other component parts, into the sound-absorbing material between the inner and outer tube, the device light weight, low resistance, eliminate good sound effects. Thus, we can see the use of imported Roots blower muffler muffler can have a good effect.
