Before designing high-pressure centrifugal fans, these factors must be determined

High-pressure centrifugal fans focus on product R&D and frequently improve product design.

The design of high-pressure centrifugal fans is often influenced by numerous factors. First, select the blade type appropriately based on actual operating conditions.

For standard fans operating at constant speed, backward-curved blades exhibit lower pressure coefficients, larger diameters, and higher efficiency. Forward-curved blades demonstrate the opposite characteristics.

Second, the transmission mode of high-pressure centrifugal fans must be determined based on actual operating conditions. For all fan equipment, considerations extend beyond diverse working environments to include speed, motor protection, bearing protection, and cooling.

Additionally, the blade outlet angle is a critical parameter serving as a fundamental reference in high-pressure centrifugal fan design.

For practical application, blades are categorized as: strongly backward-curved blades, backward-curved circular blades, backward-curved straight blades, and backward-curved wing blades; radial outlet blades and radial straight blades; forward-curved blades and strongly forward-curved blades.

Simultaneously, attention must be paid to rationally determining the number of blades. Beyond the above, the primary geometric dimensions of the inlet and outlet of the high-pressure centrifugal fan impeller also require rational determination.

The impeller assembly is a critically important component of fan equipment, as it is the part responsible for transferring energy to the gas. Therefore, its design quality significantly impacts the performance of the entire machine.

Generally, the ability to reasonably determine these factors plays a crucial role in the performance parameters of high-pressure centrifugal fan units.

Simultaneously, when designing high-pressure centrifugal fan blades, focus must be placed on the blade outlet angle.
