Proof fans in the fan duct and wind chamber test selection principles
Proof fans in duct breeze wind chamber volume selection principles. Wind gauging wind error, air flow test is unlikely, pressure is not high, and a given fan duct is only applicable to a specification of the gas flow characteristics of the test.
Qingdao proof fans
Usually low-speed fan AC 50Hz and a portion 10 000 r brushless DC fan / min or less can choose this wind gauging the wind, Hair Dryers manufactured by simple, according to the standard size of the state, according to the fan manufacturer Available standard size prescribed by the State, fan manufacturers can manufacture their own hairdryers.
Accuracy plenum wind volume, the error is small, air volume test, the pressure is high, generally 400 Hz high-speed ventilation hunger and a portion higher than the 10 000 r / min brushless DC fans may prefer to use this plenum volume wind : a plenum fan is applicable to test features a variety of specifications, formulas, simply change to a different installation disk.
