System composition of multi-stage blower

Multi stage blower is an efficient and energy-saving ventilation equipment widely used in industrial production, environmental protection, agriculture and other fields. It achieves high wind pressure and airflow output through the series operation of multiple impellers. This article will introduce the main system components of multi-stage blowers.

1. Body structure

The body structure of a multi-stage blower mainly includes the casing, air inlet, air outlet, bearing seat, and other parts. The casing is used to support and protect the internal impellers and bearings, the air inlet and outlet are used to guide the airflow in and out respectively, and the bearing seat is used to support the rotation of the rotor.

2. Rotor system

The rotor system is the core component of a multi-stage blower, consisting of a main shaft, impeller, balance plate, etc. The main shaft connects various impellers to transmit power; The impeller is responsible for compressing and transporting gas; The balance disk is used to balance the axial force of the rotor and ensure its stable operation.

3. Sealing system

The sealing system is a key component in preventing gas leakage, mainly including shaft seals, casing seals, etc. Shaft seals are used to seal the gap between the main shaft and the bearing seat, preventing gas leakage; The casing seal is used to seal the gaps between the casing and the air inlet and outlet.

4. Cooling system

Multi stage blowers generate a large amount of heat during operation, therefore a cooling system is required to maintain the normal operation of the equipment. The cooling system mainly includes two methods: air cooling and water cooling, which respectively use air and circulating water to remove the heat generated by the equipment.

5. Lubrication system

The lubrication system is used to provide lubricating oil for the bearings, gears, and other components of multi-stage blowers, reducing friction losses and extending the service life of the equipment. The lubrication system includes lubrication oil tank, oil pump, oil pipeline and other parts.

6. Control system

The control system is used to monitor and control the operating status of multi-stage blowers, including parameters such as temperature, pressure, and flow rate. The control system can adjust the operating parameters of the equipment according to actual needs to achieve automated control.

In summary, a multi-stage blower consists of multiple components such as the body structure, rotor system, sealing system, cooling system, lubrication system, and control system. Understanding the composition and working principles of these systems can help us better use and maintain multi-stage blowers, ensuring stable operation and efficient performance of the equipment.
