How to select the side channel blower

EVP has become one of the world’s influential manufacturers of compression vacuum equipment. As a pioneer of compressed vacuum technology, we have high-pressure fans, high-pressure blowers, vortex air pumps, side flow fans, ring fans, vortex cyclones, vacuum blower, regeneration fans and other products in pneumatic transportation system, vacuum lifting and clamping system, packaging machine, sewage treatment, fish pond aeration, chemical and pharmaceutical, dental vacuum suction machine, environmental protection engineering, metallurgy, petroleum and so on Natural gas, surface treatment technology, electronic and power industries have a widerange of applications.

How to select the side channel blower

All blowers are based on the selection curve to select the appropriate blower, the curve is divided into two kinds, namely pressure selection curve and vacuum selection curve. Before selection, determine the use of the blower, and then decide whether to choose the pressure form or the vacuum form.

All blowers are based on the selection curve to select the appropriate blower, the curve is divided into two kinds, namely pressure selection curve and vacuum selection curve. Before selection, determine the use of the blower, and then decide whether to choose the pressure form or the vacuum form.

If you choose pressure form, you only need to look at the curves in the box on the right. For example, a 150 mbar and 2 m3 / min side channel blower is now required. So how to choose?

Find the 150 mbar axis, and then find the 2 m3 / h line. Extending two lines will have an intersection called a work point. After the working point is determined, the appropriate blower can be selected.

Then, you will find that there are many curves that can satisfy the work point. Generally speaking, the blower in the upper right corner of the working point can meet these parameters. At this point, the curve close to this point should be selected, which means small power and cost-effectiveness.

Do you know the principle of the side channel blower?

A machine in which the side channel blower is capable of producing high pressure increments to the fluid being processed. The blower is composed of an impeller and a peripheral annular passage is arranged in the shell. During use, the impeller does not contact with surrounding parts during operation, eliminating all lubrication related problems and wear.

The side channel blower is suitable for different application fields, and is designed to meet various needs of processing air, gas and liquid in pressure and compression. In addition to the standard design blower special configuration for vertical or horizontal coupling and double face mechanical seal; energy-saving fan, explosion-proof fan installation in the potential explosion hazard area.

In addition, all our fans can be anodized with special protection of impregnation, sealing, stainless steel bolts and screws and corrosive gases.
