2HB powerful dust suction high-pressure fan, high-pressure particle dust suction fan

The vortex exhaust fan can be installed at any angle and securely fixed to a horizontal and rigid foundation or base with screws. The basic weight is approximately equivalent to that of a vortex air pumpThree times or more is the standard.

Special attention should be paid to whether the base is uneven. If so, the machine may deform when the screws are tightened! Shock absorbers can be installed to reduce noise. When the ventilation duct is not connected to the suction port, in order to prevent the inhalation of dangerous or foreign objects, please install a wire or filter. Parameter selection of vortex exhaust fan

The main parameters for selection are power, air volume, and wind pressure(requires certain requirements to calculate), voltage, etc. Due to the widespread use of vortex air pumps, their selection method is the same as that of high-pressure fans. Generally speaking, the following two steps need to be followed: 1. Determine the function of the high-pressure fan used on site, whether it is suction or blowing, and find the corresponding pressure flow curve of the high-pressure fan; If the curve is misread, sometimes the selected product cannot be used; 2. Based on the calculated pressure and flow rate, find the working curve above the corresponding working point that satisfies both pressure and flow rates on the curve graph; Then select the high-pressure fan model based on the working curve; As long as it is a different work site, its requirements for pressure and flow rate are different, so in order to obtain relatively accurate data, relevant calculations need to be carried out. This needs to be done by professional designers or consulted with professional companies.

Fan noise and its control technology
The frequency spectrum of fan noise is a composite spectrum, which is the superposition of blade passing frequency and broadband aerodynamic noise components. The frequency of blade passage is determined by the following equation:
Fn=Nbn/60 Hz
Where:
B -- Number of blades
N - The number of revolutions per minute of the ventilation fan
N - Homophonic ordinal: n=1 (fundamental frequency), n=2 (second harmonic)
The sound level of fan noise is not only related to the structural form of the fan, but also to its working stateIt is related to the total pressure and air volume.
