Roots blower for 7.5kw with 12 month warranty

The performance and system requirement of Roots blower

1.the impeller of Roots blower and lubrication system

1.1 Direction of turning:For the fan belt wheel (coupling), the counterclockwise on the left side as the positive direction;clockwise on the right side as the positive direction .All accessories of Roots blower including base, actuator, import and export of silencer, pressure gauge, safety valve, flexible joint, check valve, cushions, anchor bolt and its fittings, etc.

1.2 Using three impeller and linear spiral belt box body, two parallel axis with trefoil impeller, the impeller and elliptical hole surface inside the case and the remain small clearance between the impeller, which the impeller always keep the correct phase, by synchronous gear will not touch each other

1.3 The impeller is nodular cast ironQT500-7 and the axis is the NO.45 high quality carbon steel.Impeller type is complex,less leakage during operation.The axis in cold state,impeller diameter 0.04mm can be made again after heating , the hydraulic pressure to the fixed position slowly, operating at a high speed axis between the impeller and keep the interference of 0.01 mm, make it not loose leaf axis at high speed.

1.4 Roots blower synchronous gear adopts spur gear structure.

1.5 The one side axis of Roots blower adopts splash lubrication,another side axis adopts grease lubricantion. Adopting splash lubrication on both ends of the dual fuel tank's fan.

1.6 Roots blower cooling way is water cooling /air cooling ,the transmission way is drive/pulley, blower fan for single stage.

1.7 Roots blower fits in motor on institutional characteristics, working conditions, environmental conditions, the motor insulation class is F, protection class is IP54, 380 v, 50 hz.

As a kind of typical gas pressurization and conveying machinery, aeration roots blower in the specific pressure area has wide applicable characteristics. Roots blower for 7.5kw with 12 month warranty The traffic is usually 0.5 ~ 800 m3 / min, up to about 1400 m3 / min, single stage work pressure of 53.3 ~ 98 kpa, two-stage series,aeration roots blower which can realize - 80 ~ 200 kpa.
