Introduction of Roots Blower
It is a volume fan, with the end face of the impeller and the front and rear covers of the fan. The principle is a rotary compressor that uses two blade-shaped rotors to make relative movements in a cylinder to compress and transport gas. This blower has a simple structure and is easy to manufacture. It is widely used in aquaculture aeration, sewage treatment aeration, and cement transportation. It is more suitable for low-pressure gas transmission and pressurization systems, and can also be used as a vacuum pump.
Classification of roots fans
Roots blowers can be roughly divided into single-stage and double-stage according to their different working methods. There is only one compression-stage blower, which we call a single-stage blower, and two single-stage blowers are connected in series to continuously A blower that performs two compressions is called a two-stage blower.
Divided by impeller head: two-lobe roots blower and three-lobe roots blower;
According to purpose: vertical kiln blower, gasification blower, aeration blower, etc .;
According to the type of medium: air blower, gas blower, hydrogen blower, sulfur dioxide blower, etc .;
Divided by transmission mode: direct-connected blower and belt-connected blower;
Divided by cooling mode: air-cooled blower, water-cooled blower and counter-current cooling blower;
Divided by structure type: vertical blower, horizontal blower, vertical shaft blower, densely integrated group blower, etc .;
Divided by the type of seal: various types of blowers such as labyrinth seals, ring seals, packing seals and mechanical seals.
