Rotary blower structure and working principle: Blower pressure range:0.1-0.5kgf/cm2 Rotary blower main components: Rotary blower with compact structure, mainly consist by the following six components:motor, air transporter, blower body, air chamber, base (and fuel tank), drip nozzle Application of rotary blower: 1.Water treatment aeration aeration 2.Hospital, laboratory aeration of sewage stirred 3.Vacuum feed of printing industry 4.Electroplating tanks, agitated aeration of industrial waste water 5.Plastic welding, air supply of gas supply 6.Spraying of burners, glass industry and others Characteristic of rotary blower: 1.Small size, large volume of air, low noise, energy saving (rotary air blower uses the principle of operating compressed air, although the volume is small, but the air volume is large, energy saving, quiet operation is other forms of fans can not match. 2.Smooth operation, easy installation 3.Excellent material, clever structure, high performance (rotary blower adopts all high-quality materials, compact structure, durable, high performance, long-term use less. 4. Maintenance is simple, less failure, long life (low speed, wear, long life.

Roots blower Bore: 50~500mm Flow capacity: 0.5~420m3/min Pressure rise: 9.8kpa~98.8kpa Vacuum: -49kpa Roots blower, sometimes called a positive displacement, or pd blower, is a machine which "pushes" a relatively constant volume of the gas handled at the inlet through to the discharge. It applies to conditions requiring high vacuum or high pressure especially in the waste water treatment plant. The main purpose of the blower is to provide constant flow of gas at different pressures. The blower consists of a cast iron casing in which two rotors with conjugate shapes rotate and are synchornised by a set of timing gears. During rotation, there is no contact between the lobes or between the lobes and the casing.
