Basic knowledge of Roots blower-Mingfeng Machinery

Roots Blowers are positive displacement Blowers. The amount of air delivered is proportional to the number of revolutions. There is always a small gap between the impeller end face, the front and rear cover of the Blower , and between the Blower impeller. The synchronization gear drives the downwind from the Blower inlet along the shell. The inner wall is transported to the side of the discharge . Roots Blowers are used in many fields such as petrochemicals, building materials, electricity , smelting, chemical fertilizers, mining, ports , textiles , food , papermaking, aquaculture and sewage treatment , environmental protection industries, etc., most of them are used to transport air , but also can be used to transport gas, Flammable, explosive and corrosive gases such as hydrogen, acetylene and carbon dioxide.

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. According to the number of impeller heads: two-lobe Roots blower and three-lobe Roots blower; according to use: vertical kiln blower, gasification blower, aeration blower, etc .; by media type: air blower, gas blower, hydrogen blower, sulfur dioxide Blowers , etc .; Divided according to transmission method: direct-connected blowers and belt-connected blowers, etc . ; According to cooling methods: air-cooled blowers, water-cooled blowers, and counter-current cooling blowers; etc. And densely integrated group blowers, etc. According to the type of seal: various types of blowers such as labyrinth seals, ring seals, packing seals and mechanical seals.
