How to choose an explosion-proof centrifugal fan


The key performance parameters of explosion-proof centrifugal fans are output power, exhaust air volume and working pressure. So what problems should people pay attention to in their usual selection? Let me take you to learn more about it below.

1. Before choosing an explosion-proof centrifugal fan, you should master the manufacturing and product quality status of overseas explosion-proof centrifugal fans in China, such as the types, specifications and models of the explosion-proof centrifugal fans manufactured and the unique main uses of various products, so that you can choose the best one. Fan. "Kuzer Fan" is a very good choice.

2. According to the different physics and physical properties of the steam transported by explosion-proof centrifugal fans, choose explosion-proof centrifugal fans with different main purposes. If transporting explosive and combustible gas, this option has explosion-proof effect; transporting corrosive gas should choose anti-corrosion and explosion-proof centrifugal fan; working in high-temperature places or transporting high-temperature steam should choose heat-resistant, etc. Kuzer's explosion-proof centrifugal fans are divided into several series according to different functions, and different requirements of customers can be considered.

3. When two or so explosion-proof centrifugal fans can be selected from the exhaust fan selection characteristic data chart, priority should be given to high efficiency, higher efficiency and smaller machine size: the one with a large adjustment range, and perhaps more aspects Relatively, deliberate and make decisions.

4. If the selected centrifugal impeller has a larger straight diameter than that of the original fan, in order to use the original motor shaft, rolling bearings and rubber bearings, etc., be sure to check the starting time of the motor and the compression resistance of the original components of the fan. The strength and the critical state speed ratio of the shaft are carried forward.

5. When selecting explosion-proof centrifugal fans, try to minimize the use of explosion-proof centrifugal fans in series or series connection. When it is unavoidable, explosion-proof centrifugal fans of the same model and characteristics should be selected to work together. When the series connection is selected, there must be a certain pipe connection between the first-stage explosion-proof centrifugal fan and the second-stage fan, and maintain the same exhaust air volume.

6. The new explosion-proof centrifugal fan used should take into account the flexible use of original machinery and equipment, suitable on-site manufacturing and installation, and safe operation.

The above is the introduction of explosion-proof centrifugal fans. We mainly sell in Hebei, Northeast, Henan, Tianjin, Shaanxi, Inner Mongolia, Shanxi, Ningxia and other regions. If you want to know more, please call our hotline!
