Abahlinzeki bedivayisi yempendulo yamandla bakukhumbuza ukuthi iziguquli zefrikhwensi zisetshenziswa kakhulu, zihlukaniswe zaba iziguquli zefrikhwensi yamandla aphansi kanye neziguquli zefrikhwensi yamandla kagesi aphezulu amaphakathi ngokuya ngamazinga kagesi. Inhloso nezimfuneko zesicelo semboni ngayinye ziyahlukahluka.
1. Ukusetshenziswa kweziguquli zefrikhwensi kuzici zokonga amandla zokuguqulwa kwemvamisa
Isici sokonga amandla se-converter frequency sibonakala ekusetshenzisweni kwamafeni namaphampu. Ngemva kokwamukela ukulawulwa kwejubane lokuvama okuguquguqukayo, izinga lokonga amandla labalandeli nemithwalo yephampu lingu-20% kuya ku-60%, ngoba ukusetshenziswa kwamandla kwangempela kwabalandeli kanye nemithwalo yepompo ngokuyisisekelo ilingana namandla wesithathu wejubane. Lapho isilinganiso sokugeleza esimaphakathi esidingwa abasebenzisi sisincane, amafeni namaphampu asebenzisa ukulawulwa kwesivinini esishintshashintshayo ukuze kuncishiswe isivinini sazo, esinomthelela obalulekile wokonga amandla. Kodwa-ke, abalandeli bendabuko namaphampu basebenzisa ama-baffles nama-valve ukulawula ukugeleza, isivinini semoto sihlala singashintshile futhi ukusetshenziswa kwamandla akushintshi kakhulu. Ngokwezibalo ezifanele, ukusetshenziswa kukagesi wama-fan nama-pump motors kubalelwa ku-31% wokusetshenziswa kukagesi kuzwelonke kanye nama-50% okusetshenziswa kukagesi ezimbonini. Ukusetshenziswa kwamadivayisi okulawula isivinini esishintshashintshayo emithwalweni enjalo kubaluleke kakhulu. Njengamanje, izinhlelo zokusebenza eziphumelelayo zifaka ukunikezwa kwamanzi okucindezelwa njalo, izinhlobo ezahlukene zabalandeli, isimo somoya esimaphakathi, kanye nokulawulwa kwejubane lokuguquguquka kwephampu ye-hydraulic.
2. Ukusetshenziswa kwe-frequency converter ohlelweni oluzenzakalelayo
Ngenxa ye-microprocessor eyakhelwe ngaphakathi engu-32-bit noma engu-16 bit kusiguquli sefrikhwensi, esinokusebenza okuhlukahlukene kwe-arithmetic logic kanye nemisebenzi yokulawula ehlakaniphile, ukunemba kwefrikhwensi yokuphumayo ngu-0.1%~0.01%, futhi ifakwe izixhumanisi zokutholwa nokuvikela okuphelele, ngakho isiguquli sefrikhwensi sisetshenziswa kabanzi ezinhlelweni ezishintshayo. Isibonelo, ukusonta, ukunwebeka, ukulinganisa, nokuqondisa ngocingo embonini ye-fiber yamakhemikhali, izithando zokushisa ingilazi eyisicaba, ukuxuba ingilazi yomlilo, imishini yokudweba onqenqemeni, imishini yokwenza amabhodlela embonini yengilazi, izinhlelo zokuphakela ezizenzakalelayo kanye ne-batching zezithando zikagesi ze-arc, nokulawula okuhlakaniphile kwamakheshi.
3, Ukusetshenziswa kweziguquli zemvamisa ekuthuthukiseni izinga lenqubo kanye nekhwalithi yomkhiqizo
Amadrayivu aguquguqukayo asetshenziswa kakhulu emikhakheni ehlukahlukene yokulawula imishini efana nokudlulisa, ukuphakamisa, ukukhishwa, namathuluzi omshini. Bangakwazi ukuthuthukisa izinga lenqubo kanye nekhwalithi yomkhiqizo, banciphise umthelela wezisetshenziswa nomsindo, futhi bandise impilo yesevisi yesisetshenziswa. Ngemva kokwamukela isilawuli sesivinini sokuguqulwa kwemvamisa, isistimu yemishini yenziwa lula, ukusebenza nokulawula kulula kakhulu, futhi abanye bangashintsha ngisho nokucaciswa kwenqubo yasekuqaleni ukuze kuthuthukiswe ukusebenza kwawo wonke amathuluzi. Isibonelo, ezimbonini zendwangu kanye nezinye eziningi, izinga lokushisa ngaphakathi komshini wokubumba lilungiswa ngokushintsha inani lomoya oshisayo othunyelwe. Amafeni ajikelezayo ngokuvamile asetshenziselwa ukudlulisa umoya oshisayo, futhi njengoba isivinini se-fan sihlala singashintshi, inani lomoya oshisayo othunyelwe lingalungiswa kuphela nge-air damper.
Uma ukulungiswa komnyango womoya kwehluleka noma kungalungiswanga kahle, kuzokwenza ukuthi umshini wokubumba ulahlekelwe ukulawula futhi uthinte ikhwalithi yomkhiqizo ophelile. Lapho i-fan ejikelezayo iqala ngesivinini esikhulu, ukugqokwa phakathi kwebhande lokushayela kanye ne-bearing kubi kakhulu, okwenza ibhande lokushayela lisebenziseke. Ngemva kokwamukela ukulawulwa kwesivinini sokuguqulwa kwemvamisa, ukulungiswa kwezinga lokushisa kungafinyelelwa ngokulungisa ngokuzenzakalelayo isivinini sesiphepho ngesiguquli samafrikhwensi, esixazulula inkinga yekhwalithi yomkhiqizo. Ngaphezu kwalokho, isiguquli semvamisa singakwazi ukuqala kalula i-fan ngemvamisa ephansi nangesivinini esiphansi, sinciphise ukuguga phakathi kwebhande lokushayela nama-bearings, sandise impilo yesevisi yemishini, futhi yonge amandla angama-40%.
4. Ukusetshenziswa kwe-frequency converter ekuzuzeni isiqalo esithambile se-motor
Ukuqala kanzima kwamamotho akubangeli nje umthelela ongathi sína kugridi yamandla, kodwa futhi kufuna umthamo oweqile kugridi. Amandla aphezulu kanye nokudlidliza okukhiqizwa ngesikhathi sokuqala kubangela umonakalo omkhulu kuma-baffle nama-valve, okulimaza impilo yesevisi yemishini namapayipi. Ngemuva kokusebenzisa isiguquli sefrikhwensi, umsebenzi wokuqala othambile wesiguquli semvamisa uzodala ukuthi isiqalo samanje siguquke sisuka ku-zero, futhi inani eliphezulu ngeke lidlule elamanje elilinganiselwe, linciphise umthelela kugridi yamandla kanye nemfuneko yomthamo wokuphakelwa kwamandla, ukwelula impilo yesevisi yemishini namavalvu, futhi futhi konga izindleko zokulungisa imishini.
