Ginshirin ginin kusurwar ruwa mai sarrafa ruwa ana amfani da shi a kasuwa a yau. Ya ƙunshi sassa uku: jujjuya jiki, murfi, da akwatin tsarin sarrafawa.
1. Jiki mai jujjuyawa: Jikin da ke jujjuyawa ya ƙunshi wurin zama na tallafi, Silinda, tankin mai, naúrar wutar lantarki, firikwensin kusurwa, zoben zamewar wutar lantarki, da sauransu.
Duk jikin da ke jujjuya ana sanya shi a kan babban mashin ɗin motar kuma yana jujjuyawa tare da shaft ɗin. An kulle shi zuwa saman babban mashigin motar ta hanyar flange mai hawa.
An haɗa flange mai hawa zuwa wurin zama mai goyan baya.
Ana shigar da ma'aunin firikwensin kusurwa tsakanin sandar piston da hannun rigar taye, kuma ana shigar da firikwensin kusurwa a wajen silinda mai.
Ana shigar da zoben zamewar wutar lantarki kuma an gyara shi a kan murfin tankin mai, kuma ɓangaren jujjuyawar sa (rotor) yana jujjuyawa tare da jujjuyawar jiki. Ƙarshen fitarwa akan rotor yana haɗi zuwa naúrar wutar lantarki, firikwensin matsa lamba, firikwensin zafin jiki, firikwensin kusurwa, da iyakance iyaka; ɓangaren stator na zoben zamewar wutar lantarki an haɗa shi da madaidaicin tasha a kan murfin, kuma an haɗa maɓallin stator zuwa tashar a cikin murfin mai sarrafawa;
An kulle sandar fistan zuwa gafamfo ruwadaure sanda.
Ƙungiyar wutar lantarki tana cikin tankin mai, wanda ke ba da iko don aikin silinda mai.
Akwai zoben ɗagawa guda biyu da aka sanya akan tankin mai don amfani yayin ɗaga mai sarrafa.
2. Rufe (wanda kuma ake kira kafaffen jiki): Ya ƙunshi sassa uku. Wani sashi shine murfin waje; sashi na biyu shine murfin murfin; kashi na uku shine taga kallo. An shigar da murfin waje kuma an gyara shi a saman murfin waje na babban motar don rufe jikin da ke juyawa.
3. Akwatin tsarin nuni na sarrafawa (kamar yadda aka nuna a cikin Hoto 3): Ya ƙunshi PLC, allon taɓawa, relay, contactor, wutar lantarki na DC, ƙugiya, hasken nuna alama, da dai sauransu. matsa lamba da sauran sigogi. Tsarin sarrafawa yana da ayyuka guda biyu: kulawar gida da kuma nesa. Hanyoyin sarrafawa guda biyu suna canzawa ta hanyar kullin matsayi biyu akan akwatin tsarin nunin sarrafawa (wanda ake kira "akwatin nuni", iri ɗaya a ƙasa).
三. Kwatanta da zaɓin injina masu aiki tare da asynchronous
A. Fa'idodi da rashin amfani da injinan aiki tare
Amfani:
1. Ramin iska tsakanin rotor da stator yana da girma, kuma shigarwa da daidaitawa sun dace.
2. M aiki da karfi obalodi iya aiki.
3. Gudun ba ya canzawa tare da kaya.
4. Babban inganci.
5. Ƙarfin wutar lantarki na iya ci gaba. Za a iya samar da wutar lantarki mai amsawa ga grid ɗin wutar lantarki, ta haka inganta ingancin grid ɗin wutar lantarki. Bugu da ƙari, lokacin da aka daidaita ma'aunin wutar lantarki zuwa 1 ko kusa da shi, karatun a kan ammeter zai ragu saboda raguwar abubuwan da ke cikin halin yanzu, wanda ba zai yiwu ba ga motocin asynchronous.
Rashin hasara:
1. Rotor yana buƙatar yin amfani da na'urar motsa jiki da aka keɓe.
2. Kudin yana da yawa.
3. Kulawa ya fi rikitarwa.
B. Fa'idodi da rashin amfani da injinan asynchronous
Amfani:
1. Rotor baya buƙatar haɗawa da wasu hanyoyin wutar lantarki.
2. Tsarin sauƙi, nauyi mai sauƙi, da ƙananan farashi.
3. Mai sauƙin kulawa.
Rashin hasara:
1. Dole ne a fitar da wutar lantarki daga wutar lantarki, wanda ke lalata ingancin grid ɗin wutar lantarki.
2. Ramin iska tsakanin rotor da stator yana da ƙananan, kuma shigarwa da daidaitawa ba su da kyau.
C. Zabin motoci
Ya kamata a ƙayyade zaɓin injiniyoyi tare da ƙimar ƙarfin 1000kW da ƙimar ƙimar 300r / min bisa ga kwatancen fasaha da tattalin arziki bisa ga takamaiman yanayi.
1. A cikin masana'antar tanadin ruwa, lokacin da ƙarfin da aka shigar ya kasance gabaɗaya ƙasa da 800kW, ana fifita injin asynchronous, kuma lokacin da ƙarfin da aka shigar ya fi 800kW, ana zaɓar injin ɗin daidaitawa.
2. Babban bambanci tsakanin injunan aiki tare da injinan asynchronous shine cewa akwai motsin motsa jiki akan na'ura mai juyi, kuma ana buƙatar saita allon tashin hankali na thyristor.
3. Sashen samar da wutar lantarki na kasata ya kayyade cewa karfin wutar lantarki a wutar lantarkin mai amfani dole ne ya kai 0.90 ko sama da haka. Motoci masu aiki tare suna da babban ƙarfin wutar lantarki kuma suna iya saduwa da buƙatun samar da wutar lantarki; yayin da injinan asynchronous suna da ƙarancin wutar lantarki kuma ba za su iya biyan buƙatun samar da wutar lantarki ba, kuma ana buƙatar biyan diyya. Don haka, tashoshin famfo sanye take da injuna asynchronous gabaɗaya suna buƙatar sanye da fuska mai amsawa.
4. Tsarin injuna masu daidaitawa ya fi rikitarwa fiye da na injinan asynchronous. Lokacin da aikin tashar famfo yana buƙatar ɗaukar duka ƙarfin samar da wutar lantarki da na'urorin zamani cikin la'akari, dole ne a zaɓi motar aiki tare.
