Centrifugal fans have different uses and models. You can't simply rely on price for comparison and selection. Instead, you need to compare in many aspects according to different use environments and application industries, so as to select the most suitable fan.
According to different pressure levels, centrifugal fans are divided into three types: high pressure, medium pressure, and low pressure. The high-pressure wind pressure is greater than 3000Pa, the medium-pressure wind pressure is between 1000Pa and 3000Pa, and the low-pressure wind pressure is less than 1000Pa, which can be respectively applied to industries with different pressure requirements. At the same time, the power consumption of fans with different pressures is also different, and the horizontal and vertical combination should be considered when selecting.
The safety factor of the fan is also an important reference index. Under normal circumstances, by calculating the air volume, air pressure, and some errors and losses of the fan, the air volume is generally selected to be 1.05-1.1, and the air pressure is a safety factor of 1.1-1.15. If the safety factor is too large, it will cause the wind turbine to run in low-efficiency areas for a long time, resulting in waste of energy and increased energy consumption; if the safety factor is too small, it will increase the potential safety hazards in the use of the wind turbine, which will easily cause production accidents and harm others. .
The size and weight of the fan must also be taken into consideration. Due to different uses, the location where the fan is installed is also different. You need to choose according to the actual use situation. Choose a fan with high efficiency and light weight when the size is the same; choose a fan with a smaller size and light weight when the efficiency is the same, and at the same time, under the same conditions, the adjustable range The bigger the fan, the more suitable it is.
Under normal circumstances, the fan is not a one-time investment, and will be used in the production and processing process for a long time after purchase. Therefore, we should not only focus on the current price and quality, but also consider the long-term economic operation effect. The reputation of the brand and the maintenance costs in the later period should also be calculated. Through comprehensive comparison, we can choose the most suitable centrifugal fan. the most important.
