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, which we call single-stage blower ventilation duct blower, and the two single-stage blowers series up for two consecutive 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. Roots blower host works Roots blower is a rotary blower, which consists of a class-type chassis with two oval wall inclusion into a cylinder (with inlet and outlet on the housing) gas, Biogas send pressure blower, one pair of each other, "engaged" (because there is a gap, in fact, do not touch) the impeller, by synchronizing gear reverse rotation at a constant speed, with two impellers "engaged", the intake spaced inlet and outlet, during rotation no internal compression of the gas passage of the cylinder from the intake port to the outlet port. Roots blower wheel between the two, between the wall and between the impeller and the impeller and the casing, both to maintain a certain clearance, in order to ensure the normal operation of the blower.
