In practical applications, these fans serve diverse functions. They are not only employed for ventilation, cooling, and dust removal but also for residential ventilation and cooling, as well as drying and selective material conveyance in agricultural production. Additionally, they can be used for pressurization and propulsion. Despite this versatility, many users remain uncertain about proper selection. First, determine the required function of the high-pressure centrifugal fan based on actual conditions and locate the corresponding pressure-flow curve for the fan. If the curve is incorrect, the selected fan equipment may be unsuitable for use. Second, based on the calculated pressure and flow rate, find the operating curve on the graph that corresponds to the working point above both the pressure and flow rate values. Next, determine the model of the high-pressure centrifugal fan equipment based on the operating curve. Note that several key technical parameters must be specified: power, air volume, and pressure. Typically, once these three parameters are determined, the equipment model can be selected. Additionally, pay attention to the installation of high-pressure centrifugal fan equipment. While the specific installation steps are likely familiar, here are some details to consider. To ensure proper operation, flat washers and spring washers must be used to tighten the screws during connection. Rubber buffer pads are recommended to support the fan's weight. This is particularly essential for high-power high-pressure fans. Many practical applications demand strict noise control. Therefore, appropriate measures should be taken during installation to reduce noise from high-pressure centrifugal fans. For instance, installing mufflers or adding a layer of sound-absorbing cotton to the equipment can be effective.
