Ukuchasana okuphezulu (> 3000 Pa), umgodi onzulu: Uhlobo lwe-Centrifugal.
Ukuchasana okuphakathi, indlela yomoya enzima: Uhlobo lokuhamba oluxutyiweyo.
3. I-fan ye-axial fan ukusebenza kakuhle η
Ukuphumelela okuphezulu kwe-ventilator ephambili ≥ 70%, kunye nenqanaba lemeko yokusebenza kufuneka libe ngaphakathi kwendawo ephezulu yokusebenza kakuhle.
Ukubeka phambili iindidi zokuwonga amandla (ezifana nokuhamba kwe-axial ye-inter-shaft, ukulawulwa kwesantya esiguqukayo).
4. Amandla e-axial flow fan ye-N (kW)
Kubalwa ngokusekwe kumthamo womoya, uxinzelelo lomoya, kunye nokusebenza kakuhle: N=
60 × 1000 × η Machine
×η Ukudluliselwa

Q×P
Nceda unikeze isicatshulwa ekufuneka siguqulelwe ngokuchanekileyo nangokutyibilikayo kuso
。
Amandla emoto kufuneka abe nomda we-10% - 15%, kwaye iimotor frequency frequency (ukugcina amandla kunye nokulungiswa kwesantya) kufuneka zikhethwe.
Abalandeli abanamandla amakhulu banokuxhotyiswa ngeenjini ezimbini / iimotor ezihambelanayo.
II. Ukhuseleko kunye neeMeko zokuthintela uqhushumbo (Kunyanzelekile)
1. Ibakala elingaqhushumbayo (linyanzelekileyo kwimigodi yamalahle)
Imigodi yerhasi: ExdⅠ (uhlobo lwemigodi olungenoqhambuka).
Irhasi ephezulu / imigodi eqhumayo: I-ExdⅠMb, kwaye ixhotyiswe ngezithinteli ezichasayo kunye nesakhiwo esingenantlantsi.
Onke amalungu enjini, ulawulo lombane, kunye nebhokisi yesiphambuka azinagqabhuko-dubulo. Izixhobo ezingaqhushumbisi zithintelwe ngokungqongqo ukuba zingene emgodini.
2. Ukungafuneki kokhuseleko (kunyanzelekileyo kwii-ventilators eziphambili)
Iiseti ezimbini zezixhobo zokuphefumla ezinomthamo ofanayo zibonelelwa kwishafti yomoya nganye (enye iyasetyenziswa kunye nenye njengenkxaso), enomzekelo ofanayo kunye neenkcukacha.
Umatshini wokukhuphela uqalisa kwimizuzu eli-10.
Ii-ventilators zasekhaya / amaqela e-ventilator akufuneki asetyenziswe njengezona zixhobo ziphambili.
3. Ukubuyisela umva umthamo wokuphefumla (unyanzelekile)
Isixhobo sokubuyisela umva umoya kufuneka sifakwe, kwaye isikhokelo somoya sinokutshintshwa kwimizuzu eyi-10.
Umthamo womoya wokubuyisela umva kufuneka ube ≥ 40% yomthamo womoya oqhelekileyo.
4. "IiNtathu eziKhethekileyo kunye neZitshixo ezimbini" kwii-ventilator zasekhaya
