Difference between compressor and blower

I need a foundation for an incinerator fan, also called an air blower or a centrifugal blowerSpecification only compressor design specifications, I wonder if it can be adoptedIf so, I should use a piston compressor, a turbo compressor, or a centrifugal compressor in this blower

Answer:

It's a little different in principle, but about the same. The blades of the centrifugal blower are different from the blades of the centrifugal compressor, so the conversion efficiency of the centrifugal blower is different, and the centrifugal compressor has a pressure expanding mechanism.
Use a high pressure blowerThe compressor is under too much pressureFrom the point of view of energy saving, blowers must be adopted, and compressors should be treated with depressurization.
The blower has no internal compression. It does not belong to volumetric type. When the compression chamber is in contact with the exhaust port, compressed air flows through the pressure side. At this point the compression is generated, and then the volume of the compression chamber decreases with the continuous rotation. Because the compression process is under full back pressure. Therefore, the efficiency is low and the noise is great.Two identical and symmetrical rotors operate in a flat end cylindrical casting case, and the rotor is kept in synchronization with the gear. The blower is usually air-cooled and oil-free. Although the blower can be designed to grade two and three compression, but due to low efficiency. Single stage compression is usually applied to low voltage applications. Blowers are commonly used for vacuum pumps and pneumatic conveying.Overview of power compressorsThere are two types of power flow: axial flow and radial flow. The former is often called a turbine or an axial compressor. The latter is often called a centrifugal compressor. The power air compressor works at constant pressure, while the displacement compressor works at constant flow. The performance of a power compressor is affected by external conditions, such as a small change in intake pressure, which can cause a great change in flow rate.
You do not have any other choice of this case, centrifugal blower is the best, and can not use the compressor, their difference is that the compressor output gas pressure, flow is small. The blower has large gas production and little pressureThere is no difference between the two, and the gap is great
