Similarities and differences between fans and compressors
I agree with panhifone. I disagree with the 409598680 compressor. The compressor is higher than the standard atmospheric pressure conditions are more used in the industry, mainly for engineering pneumatic control, power device with compressed air or in the production process of process medium pressure transmission and meet the need of process.
The biggest difference is that in the case of the same power consumption, the fan produces large wind, low wind pressure, and generally directly out of the wind. Compressor on the contrary, resulting in a small amount of wind, but the wind pressure can be very high, that is, the above friends said compressed air, generally need to come with their own or additional compressed air storage tank, after the pressure transfer.Because of the different working parameters, the structure is also quite different.
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.
Agree, upstairs! The use of the two is different. The fan is used for air circulation, while the compressor's compressed gas is used in places less than the standard atmospheric pressure.
