Roots blower is a kind of mechanical equipment commonly used in industry and construction, it is mainly composed of the following parts.

1. Casing: The casing is the outer shell of the Roots blower usually made of steel plate, cast iron or cast steel.

Inside the casing is the Roots impeller and impeller space.

2. Roots impeller: The Roots impeller is a component of the Roots blower, which usually consists of two mutually rotating impellers.

The blades on these impellers are mounted at specific angles and clearances to produce gas movement and compression during rotation.

3. Drive unit: The drive unit is the source of power for the Roots blowerand is usually an electric motor, engine or other type of power unit.

The drive unit transmits power through the shaft to the Roots impeller, which causes it to rotate.

4. Inlet and outlet piping: The inlet and outlet piping is the channel that connects the Roots blower to its surroundings, and is usually made of metal pipe or hose.

The inlet piping brings air or other gases into the Roots blower, while the outlet piping discharges the compressed gases.

5. Control system: The control system is an important part of the Roots blower, which monitors and controls the operating status of the blower.

The control system usually includes sensors, meters, valves and electronic controllers.

In addition to this, Roots blowers may also include auxiliary equipment such as cooling systems, filters, mufflers and discharge valves to ensure the normal operation and safe performance of the blower.

In summary, Roots blowers are mainly composed of a casing, Roots impeller, drive unit, inlet and outlet piping, and control system, etc. The coordinated operation of these components produces powerful airflow and compression to meet the gas processing needs of a variety of industrial and construction sectors.
