Kambani yesimende 2500 t/d mutsara wekugadzira unotsigira 4.5MW tsvina yekupisa magetsi system, condenser inotenderedza mvura inotonhorera kuburikidza neinotonhodza tower yakaiswa pane inotonhorera shongwe fan kutonhora kwemhepo. Mushure menguva yakareba yekushanda, iyo yemukati yekutonhora fan drive uye simba chikamu cheiyo inotonhorera shongwe ichaita kuti inotonhorera shongwe fan izungunuke zvakanyanya, zvichikanganisa kushanda kwakachengeteka kwefani, uye kune hombe inogona kuitika njodzi. Kuburikidza nekushandiswa kweiyo yedu magineti mota shanduko, kubvisa chinodzikisira uye kubatanidza iyo refu shaft, kudzivirira vibration, kuve nechokwadi chekuchengetedza uye kugadzikana kushanda kwehurongwa. Zvichakadaro, simba rekuchengetedza simba riri pachena mushure mekushandiswa kwechigarire magineti mota.
Background
Iyo mota yekurasa kupisa kwemagetsi kutonhora shongwe fan inotora asynchronous Y akateedzana mota, inova ndiyo midziyo inofanira kubviswa mumhando yepamusoro-inopedza simba-inopedza kuseri kwemagetsi michina. Iyo inoderedza uye mota dhiraivha yakabatana neakareba shaft inosvika 3m kureba, mushure menguva refu yekushanda, kupfeka uye kubvaruka kwechidzikisira uye dhiraivha shaft zvinokonzeresa vibration, izvo zvinotokanganisa kushanda kwakachengeteka kwemidziyo, uye inoda kuvandudzwa, asi mutengo wakazara weseti yese yekutsiva wakakwira kupfuura mutengo wePM motors, saka zvinokurudzirwa kugadzirisa mota yePM kudzivirira kuzunguzika. Nekudaro, iyo yakazara yekutsiva mutengo weseti yakakwana yakakwira, kana ichienzaniswa neanogara magineti mota, musiyano wemutengo hauna kukosha, saka zvinokurudzirwa kutsiva mota yefan neyepamusoro-inoshanda magineti yakaderera-kumhanya yakananga-drive mota, iyo ine simba rakajeka rekuchengetedza simba mumunda weindasitiri.
Retrofit zvinodiwa uye ongororo yehunyanzvi
Iyo yepakutanga fan drive system ndeye asynchronous mota + dhiraivha shaft + inoderedza, ine zvinotevera zvikanganiso zvehunyanzvi: ① Iyo dhiraivha maitiro akaomarara, nekurasikirwa kwakanyanya uye kuderera kwekuita;
② Kune zvikamu zvitatu zvekukundikana kwezvikamu, kuwedzera basa rekugadzirisa uye kugadzirisa;
③ Mutengo wehunyanzvi hwekudzikisira zvikamu uye lubrication wakakwira;
④No frequency conversion speed control, haikwanise kugadzirisa kumhanya, zvichikonzera kutambisa simba remagetsi.
Yakakwirira-inoshanda magineti yakaderera-kumhanya yakananga dhiraivha nzira ine zvinotevera zvakanakira:
① Kunyanya kushanda nesimba uye kuchengetedza simba;
② inogona kusangana zvakananga nekumhanya kwemutoro uye torque zvinodiwa;
③Hapana chinodzikisira uye dhiraivha shaft, saka chiyero chekutadza kwemechini chakaderedzwa uye kuvimbika kunovandudzwa;
④ inotora frequency converter control, kumhanya siyana 0 ~ 200 r/min. Naizvozvo, chimiro chemidziyo yekutyaira inoshandurwa kuita yakakwirira-inoshanda magineti yakaderera-kumhanya yakananga-motokari mota, inogona kutamba hunhu hwekutenderera kwakadzika kumhanya uye yakakwira torque, kuderedza kukundikana kwechishandiso, uye mutengo wekugadzirisa uye kuoma kwekugadzirisa kunoderedzwa zvakanyanya, uye kurasikirwa kunoderera. Kuburikidza nekugadziriswa kwechigarire magineti yakakwira yakaderera kumhanya yakananga dhiraivha inochengetedza ingangoita 25% yemagetsi emagetsi uye inozadzisa chinangwa chekudzikisa mutengo uye kushanda zvakanaka.
Retrofit purogiramu
Zvinoenderana nemamiriro esaiti uye zvinodiwa saiti, isu tinogadzira yakakwirira-inoshanda magineti yakaderera-kumhanya yakananga-dhiraivha mota, kuisa mota uye fan panzvimbo, uye kuwedzera frequency converter control kabati mukamuri yemagetsi, kuitira kuti yepakati idzore. inogona kudzora otomatiki yekutanga-kumira uye kugadzirisa kutenderera kumhanya. Iyo mota inotenderera, inotakura tembiricha uye vibration yekuyeresa zviridzwa zvinotsiviwa panzvimbo uye inogona kutariswa nepakati control room. Iwo maparamita echinyakare uye matsva madhiraivha masisitimu anoratidzwa muTafura 1, uye mafoto esaiti isati yatanga uye mushure meshanduko inoratidzwa muMufananidzo 1.

Mhedzisiro
Mushure meiyo inotonhorera fan system yeinotenderera shongwe yemarara kupisa magetsi ekugadzira yashandurwa kuita magineti akananga-dhiraivha mota, kuchengetedzwa kwesimba remagetsi kunosvika 25%, kana fan inomhanya iri 173 r/min, mota iripo iri 42 A. , zvichienzaniswa nemotokari yemazuva ano ye58 A isati yashandurwa, simba remotokari imwe neimwe inoderedzwa ne8 kW pazuva, uye maviri acho anochengetedza 16 kW, uye nguva yekumhanya inoverengwa se 270 d pagore, uye mutengo wepagore wekuchengetedza i16 kW×24 h×270 d×0.5 CNY/kWh=51.8 miriyoni yeYuan. 0.5 yuan/kWh = 51,800 CNY. Huwandu hwekudyara hwepurojekiti i250,000 CNY, nekuda kwekudzikiswa kwekudzikisa, mota, dhiraivha shaft yekutenga mutengo we120,000CNY, uku ichideredza kurasikirwa kwemidziyo nguva yekudzikira, kudzoreredza kutenderera kuri (25-12) ÷ 5.18 = 2.51 (makore ) Chishandiso chekare chisingashande chinopedza simba chinobviswa, uye midziyo inoshanda zvakachengeteka uye zvakanaka, ine mabhenefiti ari pachena ekudyara uye mashandiro akachengeteka.
