Umgaqo osisiseko we fan Ummiselo kukufumana iimeko zokusebenza ezifunekayo ngokutshintsha indlela yokusebenza yomtshini ngokwawo okanye igophe lophawu lwenethiwekhi yombhobho wangaphandle.Ngophuhliso oluqhubekayo lwenzululwazi kunye netekhnoloji, itekhnoloji yokulawulwa kwesantya se-AC isetyenziswa ngokubanzi. Ngokusebenzisa isizukulwana esitsha sezinto zombane ezilawulwa ngokupheleleyo, ukuhamba kwefeni kunokulawulwa ngokutshintsha isantya semoto ye-AC ngesiguquli samaza, esinokuthi sinciphise ilahleko yamandla ebangelwe yindlela yokuhambahamba kwangaphambili.

Umgaqo wokonga umbane wommiselo wokuguqulwa kwamaxesha:

Xa ivolumu yomoya ifuna ukwehliswa ukusuka kwi-Q1 ukuya kwi-Q2, ukuba kusetyenziswa indlela yokulawula umcephe, indawo yokusebenza iyatshintsha ukusuka ku-A kuye ku-B, uxinzelelo lomoya lonyuka laya kwi-H2, kwaye amandla eshafti P2 ancipha, kodwa hayi kakhulu. Ukuba umgaqo wokuguqulwa kwamaxesha amkelwe, indawo yokusebenza yefeni ivela ku-A ukuya ku-C. Kuyabonakala ukuba phantsi kwemeko yokuba ivolumu yomoya efanayo i-Q2 yanelisekile, uxinzelelo lomoya i-H3 luya kuncipha kakhulu kwaye amandla ancitshiswe

I-P3 yancitshiswa kakhulu. Ukulahleka kwamandla kugcinwe △ P = △ Hq2 iyalingana nendawo ye-BH2H3c. Ukusuka kuhlalutyo olungentla, sinokwazi ukuba uguquko lommiselo yindlela efanelekileyo yokulawula. I-blower yamkela umgaqo wokuguqula amaza, ayizukuvelisa ilahleko yoxinzelelo olongezelelekileyo, isiphumo sokugcina amandla siyaphawuleka, hlengisa uluhlu lwevolthi yomoya ye-0% ~ ~ ~ 100%, efanelekileyo kuluhlu olubanzi lwemigaqo, kwaye amaxesha amaninzi phantsi komsebenzi ophantsi wokulayisha. Nangona kunjalo, xa isantya sefeni sincipha kwaye nomthamo womoya uyehla, uxinzelelo lomoya luya kutshintsha kakhulu. Umthetho olinganayo we fan ngolu hlobo lulandelayo: Q1 / Q2 = (N1 / N2), H1 / H2 = (N1 / N2) 2, P1 / P2 = (N1 / N2) 3

Kuyabonakala ukuba xa isantya sincitshisiwe saya kwisiqingatha sesantya sokuqala esilinganisiweyo, inqanaba lokuhamba, uxinzelelo kunye neshafti yamandla kwindawo ehambelana nokusebenza yehla ukuya kwi-1/2, 1/4 kunye ne-1/8 yoqobo, ethi yeso sizathu sokuba umgaqo wokuguqulwa kwamaxesha ungonga umbane kakhulu. Ngokweempawu zommiselo wokuguqulwa kwamaxesha, kwinkqubo yokucocwa kwelindle, itanki yomoya ihlala igcina inqanaba lolwelo eliqhelekileyo le-5m, kwaye i-blower iyacelwa ukuba iqhube uluhlu olubanzi lokuhamba komgaqo phantsi kwemeko yoxinzelelo oluphuma rhoqo. Xa ubunzulu bohlengahlengiso bukhulu, uxinzelelo lomoya luya kwehla kakhulu, olungenako ukuhlangabezana neemfuno zenkqubo. Xa ubunzulu bohlengahlengiso buncinci, abunakubonisa izibonelelo zokonga umbane, kodwa wenze isixhobo sibe nzima, ixesha elinye lotyalo-mali lonyukile. Ke ngoko, phantsi kwemeko yokuba itanki yomoya yale projekthi kufuneka igcine ulwelo oluyi-5m, kucacile ukuba ayifanelekanga ukwamkela imo yolawulo yokuguqulwa kwamaxesha.

Isixhobo sokungenisa isikhombisi sokulawula isixhobo sixhotyiswe ngeseti yokuhlengahlengisa i-Angle yesikhokelo kunye ne-inlet yesikhokelo sokungena kufutshane nendawo yokutsala le blower. Indima yayo kukwenza ukujikeleza komoya ngaphambi kokungena kwi-impeller, kubangele isantya sokujija. Isikhokelo sesikhonkwane sinokujikelezwa kwi-axis yayo. I-Angle nganye yokujikeleza kweleyidi kuthetha ukuguqulwa kwesakhelo sokufakwa kweleyile ye-blade, ukuze ulwalathiso lomoya ojikelezayo ungene kwi-fan impeller itshintshe ngokufanelekileyo.

Xa isikhokelo ufakelo blade Angle 0 = 0 °, blade yesikhokelo ngokusisiseko ayinampembelelo ekungeneni komoya, kwaye ukuhamba komoya kuya kungena kungena kwi-blade ye-impeller ngendlela ye-radial. Xa i-0 BBB 0 °, i-vanelet yesikhombisi sokungena iya kwenza isantya esipheleleyo sokungena kwe-airflow engena kwi-Angle ecaleni kwendlela ejikeleze isangqa, kwaye kwangaxeshanye, inefuthe elithile lokujijisana kwisantya sokungena komoya. Esi sijikelezo sangaphambi kokujikeleza kunye nesiphumo sokukhonkotha kuya kukhokelela ekwehleni komjikelo wokusebenza kwe fan, ukuze utshintshe iimeko zokusebenza, kwaye uqaphele umthetho wokuhamba kwe fan. Amandla okusindisa umgaqo wokungena kwesikhokelo se-vane.

Thelekisa iindlela ezahlukeneyo zommiselo

Nangona uhlengahlengiso lokuguqulwa kwamanqanaba e-centrifugal blower uhlengahlengiso lubanzi kakhulu, lunefuthe elibalulekileyo ekongeni umbane, kodwa ngenkqubo yenkqubo inikwe umda ziimeko zenkqubo, uluhlu lokuhlengahlengisa kuphela yi-80% ~ 100%, inqanaba lokuhamba kokuhamba litshintshile kancinci, iindlela zokuguqula uhlengahlengiso kunye nesikhokelo sokufumana umahluko wamandla amabini asetyenzisiweyo akukho mkhulu, ke imowudi yolawulo lwe-inverter, ukonga umboniso okhethekileyo ukuba ungaphumi, uphulukana nokukhetha intsingiselo. I-blower ngemowudi yokulawula i-vane yesikhokelo inokuhlengahlengisa ivolumu yomoya (50% ~ 100%) kuluhlu olukhulu phantsi kwemeko yokugcina uxinzelelo lwentengiso rhoqo, ukuze kuqinisekiswe umxholo ozinzileyo weoksijini enyibilikisiweyo kwilindle kwaye ugcine amandla noko. Ke ngoko, isantya esiphezulu sefeni ye-centrifugal kunye nemowudi yolawulo lwe-vane kufuneka ikhethwe njengokhetho lwezixhobo kule projekthi. Kwangelo xesha, ukuze ibonakalise ngcono amandla okonga umbane, kumbane wamandla amakhulu we-centrifugal fan, ingqalelo kufuneka ihlawulwe kukhetho lokuxhasa iimoto, njengokusebenzisa i-10kV yeemoto eziphezulu, ikwanceda ukunciphisa ukusetyenziswa kwamandla .
