Isisekelo esiyisisekelo se- fan umthethonqubo ukuthola izimo zokusebenza ezidingekayo ngokushintsha ijika lokusebenza lomlandeli uqobo noma ijika lesici senethiwekhi yepayipi yangaphandle.Ngokuthuthuka okuqhubekayo kwesayensi nobuchwepheshe, ubuchwepheshe bokulawulwa kwejubane le-AC busetshenziswa kabanzi. Ngokusebenzisa isizukulwane esisha sezinto ezilawulwa ngokuphelele, ukuhamba kwe-fan kungalawulwa ngokushintsha ijubane le-AC motor ne-frequency converter, enganciphisa kakhulu ukulahleka kwamandla okubangelwa yimodi yangaphambilini yokulawula ukugeleza.

Isimiso sokonga amandla somthetho wokuguqulwa kwemvamisa:

Lapho ivolumu yomoya idinga ukwehliswa isuke ku-Q1 iye ku-Q2, uma indlela yokulawula impintsha yamukelwa, indawo yokusebenza iyashintsha isuke ku-A iye ku-B, ingcindezi yomoya inyuka iye ku-H2, namandla e-shaft P2 ancipha, kodwa hhayi kakhulu. Uma umthetho wokuguqula imvamisa wamukelwa, indawo yokusebenza yomlandeli isuka ku-A iye ku-C. Kungabonakala ukuthi ngaphansi kwesimo sokuthi ivolumu yomoya efanayo iQ2 yenelisekile, ingcindezi yomoya i-H3 izokwehla kakhulu namandla anciphise

I-P3 yehliswe kakhulu. Ukulahleka kwamandla kulondolozwe △ P = △ Hq2 ilingana nendawo BH2H3c. Kusukela ekuhlaziyweni okungenhla, siyazi ukuthi umthethonqubo wokuguqulwa kwemvamisa kuyindlela ephumelelayo yokulawula. I-blower isebenzisa umthethonqubo wokuguqulwa kwemvamisa, ngeke ikhiqize ukulahleka kwengcindezi eyengeziwe, umphumela wokonga amandla uyaphawuleka, ulungise ibanga levolumu yomoya engu-0% ~ ~ ~ 100%, elifanele izinhlobonhlobo zomthethonqubo, futhi kaningi ngaphansi kwezikhathi zomsebenzi ophansi. Kodwa-ke, lapho ijubane le fan lincipha futhi ivolumu yomoya incipha, ingcindezi yomoya izoshintsha kakhulu. Umthetho olinganiselayo womlandeli ulandelayo: Q1 / Q2 = (N1 / N2), H1 / H2 = (N1 / N2) 2, P1 / P2 = (N1 / N2) 3

Kungabonakala ukuthi lapho isivinini sehliswa saba uhhafu wejubane elilinganisiwe lokuqala, izinga lokugeleza, ingcindezi namandla we-shaft wezimo ezihambisanayo zokusebenza kwehlela ku-1/2, 1/4 no-1/8 woqobo, yisizathu sokuthi umthethonqubo wokuguqulwa kwemvamisa ungonga kakhulu ugesi. Ngokuya ngezimpawu zomthethonqubo wokuguqulwa kwemvamisa, kunqubo yokwelashwa kwendle, ithangi le-aeration lihlala ligcina izinga elijwayelekile loketshezi elingu-5m, futhi oshayayo kudingeka ukuthi enze umthethonqubo wokugeleza ohlukahlukene ngaphansi kwesimo sokucindezela kokuphuma njalo. Lapho ukujula kokulungiswa kukhulu, ingcindezi yomoya izokwehla kakhulu, engakwazi ukuhlangabezana nezidingo zenqubo. Lapho ukujula kokulungiswa kukuncane, akukwazi ukukhombisa izinzuzo zokonga amandla, kepha kwenze idivayisi ibe yinkimbinkimbi, ukutshalwa kwemali kwesikhathi esisodwa kukhuphukile. Ngakho-ke, ngaphansi kwesimo sokuthi ithangi le-aeration lale phrojekthi lidinga ukugcina izinga lamanzi elingu-5m, kusobala ukuthi akulungile ukwamukela imodi yokulawula imvamisa.

Idivayisi yokulawula i-inlet umhlahlandlela we-inlet ifakwe iqoqo lezinto eziguquguqukayo ze-Angle guide kanye ne-inlet guide vane eduze kwendawo yokudonsa ye-blower. Iqhaza lalo ukwenza ukugeleza komoya kujikeleze ngaphambi kokungena emfuleni, kudale isivinini esisontekile. I-blade yomhlahlandlela ingazungezwa izungeze i-eksisi yayo. Ukujikeleza ngakunye kwe-blade kusho ukuguqulwa kwe-Angle blade ukufakwa kwe-Angle, ukuze ukuqondiswa komoya kuhele impeller fan kushintshe ngokufanele.

Lapho ukufakwa komhlahlandlela i-Angle 0 = 0 °, i-blade yomhlahlandlela ngokuyisisekelo ayinamthelela ekungeneni komoya okungena, futhi ukuhamba komoya kuzogeleza kungene ku-impeller blade ngendlela ebushelelezi. Lapho u-0 BBB 0 °, i-vane guide ye-inlet izokwenza isivinini esiphelele sokungena kwe-airflow kungene i-О Angle ngokuya nge-velocity eyisiyingi, futhi ngasikhathi sinye, iba nomthelela othile wokuphithizela kusivinini se-inlet airflow. Lo mphumela wangaphambi kokuzungezisa nokuphamba uzoholela ekwehleni kwejika lokusebenza kwabalandeli, ukuze kuguqulwe izimo zokusebenza, futhi kufezekiswe umthethonqubo wokugeleza kwabalandeli. Isimiso sokonga amandla somthethonqubo we-inlet umhlahlandlela we-vane.

Ukuqhathanisa izindlela ezahlukahlukene zomthethonqubo

Yize ukuguqulwa kokuvama kokuguqulwa kwebanga le-centrifugal blower kubanzi kakhulu, kunomthelela omkhulu ekulondolozeni amandla, kepha ngenqubo yenqubo ikhawulelwe ngezimo zenqubo, ibanga lokulungisa liyi-80% ~ 100% kuphela, isilinganiso sokugeleza kwesihlobo sishintshe kancane, izindlela zokuguqula imvamisa yokuguqula kanye nomhlahlandlela une umehluko wamandla amabili asetshenzisiwe awumkhulu, ngakho-ke imodi yokulawula i-inverter, umbukiso okonga amandla ongaphumi, ilahlekelwa ukukhetha incazelo yayo. Oshayayo onemodi yokulawula i-vane angalungisa ivolumu yomoya (50% ~ 100%) ebangeni elikhudlwana ngaphansi kwesimo sokugcina ingcindezi yokuphuma njalo, ukuze kuqinisekiswe okuqukethwe okuzinzile komoya-mpilo oncibilikisiwe endle bese konga amandla ngokuqhathaniswa. Ngakho-ke, umlandeli wejubane elikhulu we-centrifugal onemodi yokulawulwa kwe-vane kufanele ikhethwe njengokukhethwa kwemishini kule phrojekthi. Ngasikhathi sinye, ukuze kubonakale kangcono umphumela wokonga amandla, we-fan yamandla amakhulu we-centrifugal, kufanele futhi kunakwe ekukhetheni imoto esekelayo, njengokusebenzisa i-10kV high voltage motor, futhi kusiza ukunciphisa ukusetshenziswa kwamandla .
