通風(fēng)管道中油煙凈化設(shè)備的比噪聲級

來源:http://m.shyrzs.com/     發(fā)布時間:2017-11-07  

  油煙凈化設(shè)備風(fēng)機選型的六大原則:

  Six principles of fume purification equipment of fan selection:

  1、山東通風(fēng)管道加工計算管網(wǎng)阻力,管網(wǎng)阻力包括局部阻力及沿程阻力。 A、局部阻力包括:變徑管、彎頭、進(jìn)風(fēng)口、出風(fēng)口等阻力 B、沿程阻力:直管的阻力;

  1, calculate pipe network resistance, pipe network resistance including local resistance and along resistance. A, local resistance include: variable pipe, elbow, inlet, outlet and other resistance B, along the resistance: straight pipe resistance;

  2、根據(jù)管網(wǎng)阻力,加上設(shè)備阻力,再加15%的系數(shù)即為風(fēng)機的全壓。注:風(fēng)機風(fēng)量=設(shè)備處理風(fēng)量;

  2, according to the pipe network resistance, plus equipment resistance, plus 15% safety factor, that is the total pressure of the fan. Note: Fan volume = equipment handling air volume;

  3、根據(jù)風(fēng)機的全壓、風(fēng)量,考慮風(fēng)機的比噪聲級,在同參數(shù)條件下,選擇比噪聲級低的風(fēng)機可以大大減少噪聲;

  3, according to the fan's total pressure and air volume, considering the specific noise level of fan, under the same parameter condition, the fan with lower noise level can reduce the noise greatly;

  4、在選擇風(fēng)機時,以三相四線制為佳選擇,如用戶無三相四線制電源,則在風(fēng)機和設(shè)備選型時請注意說明;

  4, in the choice of fan, the three-phase four wire system is the best choice, such as the user without three-phase four wire power supply, in the fan and equipment selection, please note;

  5、單臺處理風(fēng)量≥8000m3/h,必須選用三相四線制風(fēng)機;

  5, a single volume is more than 8000m3/h, must use the three-phase four wire fan;

  6、風(fēng)機應(yīng)有獨立的電源開關(guān)。

  6. Fan should have independent power switch.
