Kugwiritsa ntchito injini ya maginito yothamanga kwambiri yothamanga kwambiri pa fani ya nsanja yozizirira kuti ipangitse mphamvu zowononga zinyalala.

Kampani ya simenti yopangira simenti 2500 t/d yomwe imathandizira 4.5MW zinyalala zopangira mphamvu zamagetsi, condenser yozungulira madzi ozizira kudzera munsanja yozizirira yomwe idayikidwa pa nsanja yozizirira ya fan fan mpweya wozizirira.Pambuyo pakugwira ntchito kwanthawi yayitali, chowongolera chozizira chamkati ndi gawo lamphamvu la nsanja yozizirira zipangitsa kuti chotenthetsera cha nsanja yozizirira chigwedezeke kwambiri, zomwe zimakhudza magwiridwe antchito achitetezo, ndipo pali ngozi yayikulu yotetezeka.Pogwiritsa ntchito kusintha kwa maginito athu, kuchotsa chochepetsera ndikulumikiza shaft yayitali, kupewa kugwedezeka, kuonetsetsa kuti dongosololi likuyenda bwino komanso lokhazikika.Panthawiyi, mphamvu yopulumutsa mphamvu ikuwonekera pambuyo pogwiritsira ntchito maginito okhazikika.

Mbiri

Galimoto ya zinyalala zopangira mphamvu zoziziritsira nsanja zimatengera asynchronous Y series motor, yomwe ndi zida zomwe zimayenera kuthetsedwa pazida zam'mbuyo zomwe zimawononga mphamvu zamagetsi.The reducer and motor drive imalumikizidwa ndi shaft yayitali pafupifupi 3m kutalika, patatha nthawi yayitali yogwira ntchito, kuvala ndi kung'ambika kwa chochepetsera ndi shaft yoyendetsa kumayambitsa kugwedezeka kwakukulu, komwe kumakhudza kale magwiridwe antchito otetezeka a zida. ikuyenera kusinthidwa, koma mtengo wathunthu wa seti yonse yosinthira ndi yokwera kuposa mtengo wa ma motors a PM, chifukwa chake akuyenera kusintha mota ya PM kuti apewe kugwedezeka.Komabe, mtengo wonse wosinthira wathunthu ndi wokwera, poyerekeza ndi maginito okhazikika amagetsi, kusiyana kwamitengo sikuli kofunikira, chifukwa chake akufunsidwa kuti asinthe mafani agalimoto ndi maginito okhazikika okhazikika otsika liwilo lolunjika pagalimoto, yomwe ili ndi zodziwikiratu zopulumutsa mphamvu m'munda wamakampani.

Retrofit zofunika ndi kusanthula luso

Dongosolo loyambirira la fan drive ndi asynchronous motor + drive shaft + reducer, yomwe ili ndi zovuta zotsatirazi: ① Njira yoyendetsera ndi yovuta, ndikuwonongeka kwakukulu komanso kuchepa kwachangu;

② Pali magawo atatu olephera, kuwonjezera kuchuluka kwa ntchito yokonza ndi kukonzanso;

③ Mtengo wa zida zapadera zochepetsera ndi mafuta ndizokwera;

④Palibe kuwongolera pafupipafupi kutembenuka kwa liwiro, sikungasinthe liwiro, zomwe zimapangitsa kuwononga mphamvu yamagetsi.

Njira yoyendetsera bwino kwambiri ya maginito otsika kwambiri ili ndi izi:

① Kuchita bwino kwambiri komanso kupulumutsa mphamvu;

② imatha kukwaniritsa mwachindunji liwiro la katundu ndi torque;

③Palibe chochepetsera ndi kuyendetsa shaft, kotero kulephera kwa makina kumachepetsedwa ndipo kudalirika kumatheka;

④ imatengera kuwongolera pafupipafupi, liwiro la 0 ~ 200 r/min.Chifukwa chake, mawonekedwe a zida zoyendetsera galimoto amasinthidwa kukhala injini yamagetsi yokhazikika yokhazikika yothamanga kwambiri, yomwe imatha kusewera mawonekedwe a liwiro lotsika komanso torque yayikulu, kuchepetsa kulephera kwa zida, komanso mtengo wokonza ndi zovuta kukonza zimachepa kwambiri, ndipo kutaya kumachepa.Kupyolera mu kusinthidwa kwa maginito okhazikika othamanga kwambiri otsika kwambiri oyendetsa galimoto amapulumutsa pafupifupi 25% ya mphamvu yamagetsi ndikukwaniritsa cholinga chochepetsera mtengo komanso kuchita bwino.

Pulogalamu ya Retrofit

Malingana ndi malo ndi zofunikira za malo, timapanga galimoto yothamanga kwambiri ya maginito otsika-liwiro, kukhazikitsa galimoto ndi fani pa malo, ndikuwonjezera kabati yosinthira ma frequency mu chipinda chamagetsi, kuti mphamvu yapakati iwonongeke. imatha kuwongolera kuyimitsidwa koyambira ndikusintha liwiro lozungulira.Zida zoyezera ma motor, kutentha ndi kugwedezeka kwazitsulo zimasinthidwa pamalopo ndipo zimatha kuyang'aniridwa ndi chipinda chowongolera chapakati.Zosintha zamakina akale ndi atsopano amagalimoto akuwonetsedwa mu Gulu 1, ndipo zithunzi za tsambalo zisanachitike komanso zitasintha zikuwonetsedwa Chithunzi 1.

Zotsatira

Pambuyo pa kuzizira kozizira kwa nsanja yozungulira ya zinyalala zopangira mphamvu zamagetsi kusinthidwa kukhala injini yokhazikika yoyendetsa maginito, kupulumutsa mphamvu yamagetsi kumafika pafupifupi 25%, pomwe liwiro la fan ndi 173 r/min, injini yapano ndi 42 A. , poyerekeza ndi injini yamakono ya 58 A isanayambe kusinthidwa, mphamvu ya injini iliyonse imachepetsedwa ndi 8 kW patsiku, ndipo magulu awiriwa amapulumutsa 16 kW, ndipo nthawi yothamanga imawerengedwa ngati 270 d pachaka, ndi ndalama zopulumutsira pachaka ndi 16 kW×24 h×270 d×0.5 CNY/kWh=51.8 miliyoni Yuan.0.5 yuan/kWh = 51,800 CNY.Ndalama zonse za polojekitiyi ndi 250,000 CNY, chifukwa cha kuchepetsa kuchepetsa, galimoto, mtengo wogula shaft wa 120,000CNY, pamene kuchepetsa kutaya kwa zipangizo zowonongeka, kuchira ndi (25-12) ÷ 5.18 = 2.51 (zaka ).Zida zakale zogwiritsa ntchito mphamvu zopanda mphamvu zimathetsedwa, ndipo zida zimagwira ntchito bwino komanso mosavutikira, zopindulitsa zodziwikiratu komanso zogwira ntchito zotetezeka.
