The selection of roots blower for pneumatic conveying is carried out from the following aspects:

The selection of roots blower for pneumatic conveying is carried out from the following aspects:

      1. Roots blowers with different performance specifications shall be selected according to the air pressure and air volume required by the production process conditions;

2. Select parts of different materials according to the corrosion of the conveying medium;

3. The cooling mode shall be determined according to the specific conditions of the work site. If there is water, the water-cooled type can be selected, and if there is no water, the air-cooled Roots blower shall be selected;

　　4. When the required air volume does not conform to the performance parameters of the blower during the production process, the rotating speed of Roots blower can be properly increased or reduced to increase or reduce the air volume of the blower. Attention shall be paid not to leave the performance parameters of the blower too far. If the speed is increased too much, the service life of the blower will be shortened, and even mechanical damage will occur.

For our pneumatic conveying system, belt coupled transmission can be selected when conveying dusty gas. Even if the rotor clearance increases due to dust wear, the flow can be adjusted within a certain range by replacing the pulley. When conveying flammable and explosive gases, direct transmission shall be preferred. If belt transmission is used, anti-static belt must be used.

For the same flow rate Roots blower, the smaller model can be selected, and the higher speed can be used, or the larger model can be used, and the lower speed can be used. The former is small in size, light in weight and high in efficiency, but has adverse effects on vibration, noise and service life; The latter is relatively stable in operation, low in noise and long in service life. However, it is larger in volume and weight and higher in cost than the former. From the perspective of economy, small models with high speed can be selected; Large models with low speed can be selected from the perspective of stability.

The correct selection of roots blower type can effectively ensure the stable operation of pneumatic conveying. The technology of pneumatic conveying system shall be comprehensively considered according to the material properties of conveyed materials, production process requirements, conveying efficiency and economy. If the selected conveying device does not match the material properties of the conveyed materials, it will cause various failures, or even fail to convey. Even if other factors are good, it is also difficult to use. So let professional people do professional things, please contact us!
