Fan selection issues
Thread Content
I encountered a problem recently when I was designing, that is, when using negative pressure induced air to transport materials, regarding fan selection, the previous design encounters were all based on previous experience, but I really don’t know how much air pressure is needed and what kind of fan to choose! For example, what we are transporting this time is pesticide powder, with a water content of less than 2%. The transport height is about 10 meters, and the length of the transport pipeline is about 15 meters. The transport pipeline uses 350 stainless steel thin-walled pipes. I would like to ask what type of fan should be selected to be able to use it without wasting resources too much. Does anyone know how to calculate it? Urgent! ! !
Powder is a solid material, why not convey it by belt?
The main reason is to consider the problem of dust pollution and the problem of moisture absorption and transformation in the air, so it can only be transported through closed pipelines. By the way, our products are mancozeb series pesticide products. If you know the properties of this product, you will know why~~~:)
Host: There is a lot of data here. Calculate the pressure drop of the entire system. If the pipeline is 15 meters long for dilute phase transportation, the gas speed is 25 meters. The pipeline uses two 45-degree elbows instead of one 90-degree elbow. The pressure drop is about 1000pa. The best design can be as low as 600pa. Square pipes should not be used for horizontal pipes, and round pipes should not be used for elbows. If the solid separation is a cyclone, the pressure drop will be between 1000-2000pa. After the pressure drop and air volume of the entire system are calculated, you can refer to the fan table for selection. When selecting, the air volume and air pressure should be slightly larger, but the air volume should not be too large, otherwise it will have the opposite effect. The solid ratio of your product can be as high as 1: The high concentration of 20 is good for dust removal, and the system pressure is no-load pressure. * The specific gravity of dusty gas.
I also need information about this. Can anyone share it?

Multi-stage centrifugal blower performance parameters Multi-stage centrifugal blowers are widely used in various smelting blast furnaces, coal washing plants, mine flotation, sewage treatment, chemical gas production and other occasions where air needs to be transported, and can also be used to transport other special gases. This series of blowers has the characteristics of high efficiency, low noise, smooth operation, few wearing parts and easy installation, operation and maintenance.

If you tell these parameters to the fan manufacturer, they will soon tell you how to choose and which one to choose?
