The difference between side flow blower and centrifugal blower

What is the purpose of a blower

Blowers belong to ventilation equipment. The boiler is enclosed, and combustion consumes oxygen in the enclosed space, generating gases such as carbon dioxide and carbon monoxide. Oxygen is a combustion aid, so ventilation involves introducing air into a closed room, which requires oxygen to assist combustion.

Characteristics of blower

Due to the frictionless operation of the impeller within the body, the blower does not require lubrication, resulting in the exhaust gas being oil-free. It is an ideal pneumatic conveying gas source for industries such as chemical and food.
2. The blower belongs to the volumetric operation blower. When in use, the flow rate changes very little with changes in pressure. But the flow rate varies with the rotational speed. Therefore, the range of pressure selection is wide, and the choice of flow rate can be achieved by selecting the desired speed.
The speed of the blower is high, and the gaps between rotors and between rotors and the body are small, resulting in less leakage and higher volumetric efficiency.
The structure of the blower determines that its mechanical friction loss is very small. Because only the bearings and gear pairs have mechanical contact in material selection, the rotor, housing, and gear ring have sufficient mechanical strength. Safe operation and long service life are major features of blower products.
The rotor of the blower has undergone static and dynamic balance verification. The finished product runs smoothly with minimal vibration.

The blowers with the above characteristics mainly include Roots blowers, side flow blowers, and multi-stage centrifugal blowers.

Side flow blowerDifference from centrifugal blower

Side flow blower, also known as vortex blower or high-pressure blower, has a small volume, compact structure, small front pump head, and generates high pressure but low flow rate. The inlet and outlet air diameters are moderate, resulting in high flow velocity.

Centrifugal blowers, due to their large impellers and pump heads, have a high air volume but low pressure, low machining accuracy requirements, and a large diameter, mainly used for conveying air.
