Roots Blower Selection and Applications

1. Principle of Roots Blower Model Selection

Firstly, we should select the model, structure, and material of the roots blower according to the performance parameters, purpose, process requirements, and application occasions to meet the required working conditions. The inlet flow and pressure rise of the roots blower shall be close to the process requirements as much as possible, so as to make the roots blower operate efficiently. Otherwise, it will cause accidents and waste of energy.

To select the model of three lobes roots blower according to the nature of the conveyed medium, the flow, and pressure required by the process flow. At the same time, we should consider the pressure loss from pipe network resistance and the flow loss.

The required airflow and pressure rise shall preferably be actually measured at the rated load of the system. If it is a new project, it can be obtained by theoretical calculation. We can also learn from the actual operation values of similar systems and make analogical calculations to master the maximum and minimum values that the system may use, so as to facilitate the model selection.

The medium temperature shall be the highest temperature in normal operation. Before selection, we need to carry out actual measurements or investigate the previous operation records of the roots blower.

Finally, we should comprehensively consider the above data according to the operation of the existing blower, and finally determine the design parameters of the Roots Blower. So as to avoid the situation that the flow and pressure of the new roots blower can not meet the actual operational needs.

2. Roots Blower Development Trend

With the development of technology, the quality of domestic roots blowers has been continuously improved and has occupied most of the domestic market. Roots blower has the characteristics of small volume, lightweight, low noise, stable and reliable operation. In this case, roots blower is widely used in most industries. For example, powder transportation (cement, feed, small pieces), vacuum packaging, water treatment (aeration), aquaculture, electroplating tank mixing, combustion furnace, pneumatic transportation, and other industries.

Roots blowers mainly convey air. With different sealing structures, roots blower can also transport flammable, explosive, and corrosive gases such as biogas, hydrogen, acetylene, and carbon dioxide. It integrates blower, motor, filter, inlet, and outlet muffler, flexible joint, safety valve, check valve, and pressure gauge. It can be equipped with a PLC signal interface, intelligent monitor, and sound insulation cover.
