M'zaka zaposachedwa, chuma cha China chakhala chikukula mofulumira, mavuto amphamvu awonjezeka kwambiri kuti akhale chigongono chachikulu cha chitukuko cha mafakitale, ndi kukwera kwachangu kwamitengo yamagetsi, mpikisano woopsa pamsika wapakhomo, kusungirako mphamvu kwakhala. kukhala vuto lalikulu lomwe likukumana ndi chitukuko cha mafakitale ambiri, makamaka kugwiritsa ntchito mphamvu ndi mafakitale akuluakulu monga petroleu-m, mankhwala, mankhwala, zitsulo, kupanga, kuteteza chilengedwe, munici-pal ndi mafakitale ena.Malinga ndi deta, mphamvu okwana ma motors mkulu ndi otsika voteji ku China ndi oposa 35000MW, ambiri a iwo ndi zimakupiza pampu katundu, ndipo ambiri a iwo ntchito mu mowa mkulu mphamvu ndi otsika dzuwa.
General zimakupiza, mpope dongosolo ambiri valavu kusintha otaya madzi kapena kupanikizika, kusokoneza lamulo ili ndi kuonjezera imfa ya maukonde chitoliro, kudya mphamvu zambiri pa mtengo, choncho, mosalephera kuwononga mphamvu ya magetsi.Ndipo chifukwa mapangidwe, dongosololi limapangidwa molingana ndi katundu wambiri, mu ntchito yeniyeni, nthawi zambiri dongosololi silingathe kuthamanga mumtundu wonse wa katundu, pali zowonjezera zambiri, kotero pali mphamvu yaikulu yopulumutsa mphamvu. .
Kugwiritsa KD600 pafupipafupi kutembenuka liwiro kuwongolera chipangizo, ndi kusintha liwiro zimakupiza, kuti kusintha zimakupiza mpweya voliyumu kukwaniritsa zofunika za ndondomeko kupanga, ndi ntchito mphamvu mowa ndi kupulumutsa kwambiri, phindu lonse mabuku.Chifukwa chake, kuwongolera kwa liwiro la ma frequency ndi njira yabwino komanso yoyenera kwambiri yoyendetsera liwiro, yomwe imatha kuzindikira kuthamanga kwa fani, ndipo imatha kupanga makina otsekera otsekeka kuti akwaniritse kupanikizika kosalekeza kapena kuwongolera nthawi zonse.
Kutembenuza pafupipafupision liwiro regulation mphamvu yopulumutsa mfundo
Malinga ndi mfundo yamakina amadzimadzi, ubale pakati pa shaft mphamvu P ndi voliyumu ya mpweya Q ndi kuthamanga kwa mphepo H kwa fan yoyendetsedwa ndi induction motor ndi motere:
“Q * H Liwiro la mota likasintha kuchokera ku n1 kupita ku n2, ubale wapakati pa Q, H, P ndi liwiro uli motere:
Zitha kuwoneka kuti voliyumu ya mpweya Q imayenderana ndi liwiro la n la mota, ndipo mphamvu ya shaft yofunikira P ndiyolingana ndi kyubu ya liwiro.Choncho, pamene 80% ya voliyumu ya mpweya ikufunika, posintha liwiro la galimotoyo kufika pa 80% ya liwiro lovomerezeka, ndiye kuti, kusintha maulendo afupipafupi kufika 40.00Hz, mphamvu yofunikira idzakhala 51.2% yokha yapachiyambi.
Monga momwe chithunzi (1) chikuwonetsedwera, mphamvu yopulumutsa mphamvu pambuyo potengera kusinthasintha kwa liwiro la liwiro imawunikidwa kuchokera pamapindi a ntchito ya fan.
Pamene voliyumu yofunikira ya mpweya ikuchepa kuchokera ku Q1 kupita ku Q2, ngati njira yosinthira damper itengedwa, kukana kwa netiweki kwa chitoliro kumawonjezeka, mayendedwe amtundu wa chitoliro amayenda mmwamba, malo ogwirira ntchito akusintha kuchokera pomwe. A kupita kumalo atsopano ogwirira ntchito B, ndipo mphamvu yofunikira ya shaft P2 ndiyofanana ndi gawo la H2 × Q2.Ngati njira yoyendetsera liwiro imatengedwa, liwiro la fani limatsika kuchokera ku n1 kupita ku n2, mawonekedwe a netiweki sasintha, koma mawonekedwe a fani amatsika, kotero mawonekedwe ake ogwiritsira ntchito amasunthidwa kuchokera ku A kupita ku C. chofunikira shaft mphamvu P3 ndi yolingana ndi dera HB × Q2.Mwachidziwitso, mphamvu ya shaft Delt(P) yosungidwa ndiyolingana ndi dera la (H2-HB) × (CB).
Poganizira za kuchepa kwa magwiridwe antchito pambuyo pakutsika komanso kutayika kwina kwa chipangizo chowongolera liwiro, kudzera mu ziwerengero zenizeni, mafani amatha kupulumutsa mphamvu pakuwongolera liwiro mpaka 20% ~ 50%.
Ubwino wowongolera liwiro losinthika
- Mphamvu ya mbali ya maukonde ndi bwino: pamene galimoto yoyambirira imayendetsedwa mwachindunji ndi ma frequency amphamvu, mphamvu yamagetsi imakhala pafupifupi 0,85 pa katundu wathunthu, ndipo mphamvu yeniyeni yothamanga ndiyotsika kwambiri kuposa 0,8.Pambuyo potengera kachitidwe ka frequency conver-rsion speed regulation, mphamvu ya mbali yamagetsi imatha kuonjezeredwa kupitilira 0.9, ndipo mphamvu yogwira ntchito imatha kuchepetsedwa kwambiri popanda chida cholipirira mphamvu, chomwe chingakwaniritse zofunikira za gridi yamagetsi. ndi kupulumutsanso ndalama zoyendetsera zida zam'mwamba.
- Zida zogwiritsira ntchito ndi kukonza ndalama zatsika: Pambuyo pakugwiritsa ntchito kusintha kwafupipafupi, chifukwa cha kusintha kwa liwiro la galimoto kuti mupulumutse mphamvu, pamene mtengo wa katundu uli wochepa, kuthamanga kwa galimoto kumachepetsedwanso, zida zazikulu ndi zipangizo zothandizira zogwirizana. monga mayendedwe amavala mocheperapo kuposa kale, nthawi yosamalira imatha kukulitsidwa, moyo wogwiritsa ntchito zida umakulitsidwa;Ndipo pambuyo pa kutembenuka kwa kutembenuka, kutsegula kwa damper kumatha kufika 100%, ndipo ntchitoyo siili pansi pa zovuta, zomwe zingathe kuchepetsa kwambiri kukonza kwa damper.Pogwiritsa ntchito ma frequency converter, amangofunika kuthira fumbi pafupipafupi, osayimitsa, kuonetsetsa kupitiliza kwa kupanga.Ndi zofunika kupanga, kusintha liwiro zimakupiza, ndiyeno sinthani mpweya voliyumu wa zimakupiza, amene osati amakwaniritsa zofunika ndondomeko kupanga, komanso amachepetsa kwambiri ntchito mwamphamvu.Pambuyo potengera ukadaulo wosinthira pafupipafupi kuti muzitha kuyendetsa liwiro, kuvala kwamakina kumachepetsedwa, ntchito yokonza imachepetsedwa, ndipo ndalama zosamalira zimachepetsedwa.
- Chida chowongolera kutembenuka pafupipafupi chikagwiritsidwa ntchito, injiniyo imatha kuyambika mofewa, ndipo yapano sipitilira nthawi 1.2 kuchuluka kwa injiniyo poyambira, popanda kukhudza gridi yamagetsi, komanso moyo wantchito wagalimotoyo. yakulitsidwa.Pazigawo zonse zogwirira ntchito, mota imatha kuwonetsetsa kuti ikugwira ntchito bwino, kuchepetsa kutayika, komanso kukwera kwabwino kwa kutentha.Phokoso ndi kuyambika kwa fani ndi kochepa kwambiri poyambira, popanda kugwedezeka kulikonse ndi phokoso.
- Poyerekeza ndi dongosolo lakale lachikale, inverter ili ndi ntchito zingapo zotetezera monga overcurrent, short circuit, overvoltage, undervoltage, kusowa kwa gawo, kutentha kutentha, etc., kuteteza bwino galimoto.
- Ntchito yosavuta komanso yosavuta kugwiritsa ntchito.Magawo monga kuchuluka kwa mpweya kapena kupanikizika kumatha kukhazikitsidwa patali ndi makompyuta kuti akwaniritse malamulo anzeru.
- Kutha kuzolowera kusinthasintha kwamagetsi amagetsi amagetsi ndikolimba, kuchuluka kwamagetsi komwe kumagwirira ntchito ndikokulirapo, ndipo makina amatha kugwira ntchito bwino pomwe magetsi amagetsi amasinthasintha pakati pa -15% ndi +10%.
