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

Kampani ya simenti ya 2500 t/d yopangira mphamvu yopangira mphamvu ya 4.5MW, condenser yozungulira madzi ozizira kudzera munsanja yoziziritsa yomwe imayikidwa pa nsanja yozizirira ya fan fan mpweya wozizira. 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 pamakhala chiwopsezo chachikulu chachitetezo. 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. Chotsitsa ndi choyendetsa galimoto chimalumikizidwa 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 a zida, ndipo ikuyenera kusinthidwa, koma mtengo wonse wa m'malo mwake ndi wapamwamba kuposa mtengo wa ma motors a PM, motero akufunsidwa kuti apewe kugwedezeka kwamagetsi. Komabe, mtengo wathunthu m'malo a seti wathunthu ndi mkulu, poyerekeza ndi okhazikika maginito Motors, kusiyana mtengo si kofunika, choncho akufuna m'malo zimakupiza galimoto ndi mkulu-mwachangu okhazikika maginito otsika-liwiro molunjika pagalimoto galimoto, amene ali zoonekeratu mphamvu yopulumutsa mphamvu m'munda mafakitale.

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 kuthamanga kwafupipafupi, 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 maginito okhazikika okhazikika othamanga kwambiri, omwe amatha kusewera mawonekedwe a liwiro lotsika komanso torque yayikulu, kuchepetsa kulephera kwa zida, komanso mtengo wokonza ndi zovuta kukonza zimachepetsedwa kwambiri, ndipo kutayika 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

Malinga ndi malo malo ndi zofunika malo, ife kupanga mkulu-mwachangu okhazikika maginito otsika-liwiro mwachindunji pagalimoto galimoto, kukhazikitsa galimoto ndi zimakupiza pa malo, ndi kuwonjezera pafupipafupi Converter kulamulira kabati mu chipinda mphamvu, kuti ulamuliro chapakati akhoza basi kulamulira chiyambi-kuyimitsa ndi kusintha liwiro rotational. Zida zoyezera ma motor, kutentha ndi kugwedezeka kwazitsulo zimasinthidwa pamalopo ndipo zimatha kuyang'aniridwa ndi chipinda chowongolera chapakati. Zosintha zamagalimoto akale ndi atsopano akuwonetsedwa mu Table 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 yamagetsi, kupulumutsa mphamvu yamagetsi kumafika pafupifupi 25%, liwiro la fan ndi 173 r / min, injini yamakono ndi 42 A, poyerekeza ndi ma motor motor 58 A isanachitike kusinthidwa, mphamvu yagalimoto iliyonse imachepetsedwa ndi 6 kW tsiku lililonse ndi 8 kW. nthawi yothamanga imawerengedwa ngati 270 d pachaka, ndipo 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, kuyendetsa shaft kugula mtengo wa 120,000CNY, pamene kuchepetsa kutaya kwa zipangizo zochepetsera nthawi, 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.
