Kuyerekeza Mitundu ya Magalimoto a Treadmill: Kusiyana Pakati pa Magalimoto a DC ndi AC

Mukagula treadmill, mawu odziwika bwino omwe mumamva ndi akuti: “Mtundu uwu uli ndi mota ya DC—yodekha komanso yosagwiritsa ntchito mphamvu zambiri.” Kapena: “Timagwiritsa ntchito ma mota a AC apamwamba kwambiri kuti tigwire bwino ntchito komanso kuti tikhale ndi moyo wautali.” Kodi izi zimakupangitsani kusokonezeka kwambiri? Kwa eni malo ochitira masewera olimbitsa thupi kapena ogulitsa ambiri, kusankha mota yolakwika kungayambitse mavuto ang'onoang'ono monga madandaulo a ogwiritsa ntchito ndi mbiri yowonongeka, kapena mavuto akuluakulu monga kulephera kwa magalimoto pafupipafupi komwe kumawonjezera ndalama zokonzera komanso kubweretsa zoopsa zachitetezo. Motoka ndiye mtima wa treadmill. Nkhaniyi ikufotokoza momveka bwino kusiyana pakati pa ma mota a DC ndi AC pankhani ya mtengo, magwiridwe antchito, ndi kukonza. Mukawerenga, mudzamvetsa bwino mtundu wa “mtima” womwe makasitomala anu kapena malo ochitira masewera olimbitsa thupi amafunikiradi.

I. Kusiyana Kwakukulu: Kodi Mfundo za DC ndi AC Motor Zimakhudza Bwanji Magwiridwe Antchito Padziko Lonse?

Izi sizikutanthauza kuti “ndi chiyani chabwino.” Kusiyana kwawo kwakukulu kuli m'njira imene amayendetsera zinthu.

Ma mota a DC amagwira ntchito pa mphamvu yolunjika. Amakhala ndi "controller" (commutator) yomwe imatembenuza njira yamagetsi kuti rotor izungulire. Ubwino wawo ndi kuyamba ndi kuyimitsa bwino ndi mphamvu yowongolera liwiro molondola kwambiri. Mutha kusintha liwiro mosavuta kuyambira 1 km/h mpaka 20 km/h mwa kusintha mphamvu yamagetsi, popanda kugwedezeka.

Ma mota a AC amagwiritsa ntchito mphamvu ya AC kuchokera ku gridi mwachindunji. Kapangidwe kake ndi kosavuta komanso kosavuta, nthawi zambiri amasintha liwiro kudzera mu kusintha kwa gawo kapena ma frequency drive osinthasintha. Amakhala ndi torque yayikulu yoyambira komanso kugwira ntchito kosalekeza. Tangoganizirani kukankha chinthu cholemera: mota ya AC ikupita patsogolo ndi mphamvu yadzidzidzi, pomwe mota ya DC ikuyenda mofulumira pang'onopang'ono komanso bwino.

Zochitika zenizeni: Pa nthawi yogwira ntchito kwambiri ku malo ochitira masewera olimbitsa thupi, munthumakina opumira matayala amodzi Ikhoza kuyatsidwa ndikuyimitsidwa kambirimbiri tsiku lililonse ndi ogwiritsa ntchito zolemera zosiyanasiyana. Mphamvu yoyambira ya mota ya AC imalola kuyankha mwachangu, kuchepetsa nthawi yodikira. Komabe, m'nyumba, ogwiritsa ntchito amaika patsogolo kuyambika kosalala komanso chete - apa ndi pomwe ubwino wowongolera molondola wa mota ya DC umawonekera.

Funso lofala kwa ogwiritsa ntchito: “Kodi zimenezi zikutanthauza kuti ma DC motors ndi apamwamba kwambiri?” Osati kwathunthu. Ngakhale kuti ma DC motors amapereka kulondola kwakukulu, “commutator” yawo yaikulu imadalira maburashi a kaboni—gawo lotha kutha. Ma AC motors ali ndi kapangidwe kosavuta komanso kolimba. Komabe, ma AC motors achikhalidwe okhala ndi liwiro lokhazikika amavutika ndi malamulo olakwika a liwiro, vuto lomwe limathetsedwa ndi ma AC motors amakono—ngakhale kuti pamtengo wokwera.

II. Mtsogoleri wa Msika Wapakhomo: Chifukwa Chake Magalimoto a DC Amalamulira

Pitani ku sitolo iliyonse yogulitsira makina oyendera matayala kunyumba, ndipo opitilira 90% ali ndi ma DC motors. Izi sizichitika mwangozi.

Ubwino waukulu ndi mawu anayi okha: luso lapamwamba kwambiri la ogwiritsa ntchito.

Chete. Ma mota a DC amagwira ntchito mopanda phokoso kuposa ma mota a AC okhala ndi mphamvu yofanana. Kuti agwiritsidwe ntchito m'zipinda zochezera kapena m'zipinda zogona, ichi ndi chinthu chofunikira kwambiri.

Yogwiritsa ntchito mphamvu zochepa. Pakanyamula katundu wochepa (kuyenda pang'onopang'ono, kuyenda mwachangu), ma mota a DC amagwira ntchito bwino kwambiri ndipo amagwiritsa ntchito mphamvu zochepa mukamayimirira. Pakapita nthawi, kusiyana kwa mtengo wamagetsi kumakhala kwakukulu.

Kusintha kwa Liwiro Losalala. Kusintha kuchoka pa kuyenda kupita ku kuthamanga kumakhala kosavuta komanso kofatsa pamabondo, zomwe zimapangitsa kuti ikhale yoyenera mabanja omwe ali ndi okalamba kapena omwe akuchira.

Kukula Kochepa. Pa mphamvu yofanana, ma DC motors nthawi zambiri amakhala opepuka komanso opapatiza, zomwe zimathandiza kuti chogwirira ntchito chikhale chosavuta kupindika ndi kusungira.

Thandizo la Deta: Kutengera ndi momwe timatsatirira msika wogulitsa ku North America, "phokoso lochulukirapo logwirira ntchito" nthawi zonse limakhala pakati pa zifukwa zitatu zazikulu zobwezeretsera makina opumira kunyumba. Magalimoto okhala ndi ma DC motors apamwamba kwambiri akuwonetsa kuchuluka kwa madandaulo otsika ndi 35% pankhaniyi. Izi ndi ndemanga za msika mwachindunji.

Nkhawa Zomwe Ogwiritsa Ntchito Ambiri Amadandaula Nazo: “Kodi ma mota a DC apakhomo amatha kulephera kugwira ntchito? Ndamva kuti akufunika kusintha maburashi a kaboni?” Izi ndizofunikira kwambiri. Ma mota a DC otsika mtengo amawonongeka mwachangu ndi burashi ya kaboni, zomwe zingafunike kukonzedwa mkati mwa chaka chimodzi kapena ziwiri. Komabe, zinthu zapakati mpaka zapamwamba tsopano zimagwiritsa ntchito ma mota a DC opanda maburashi. Izi zimalowa m'malo mwa maburashi a kaboni enieni ndi zowongolera zamagetsi, zomwe zimachotsa kuwonongeka, kuphulika, ndi mavuto a phokoso pomwe zimawonjezera nthawi ya moyo. Mukamagula, nthawi zonse fotokozani kuti: “Kodi ndi mota ya DC yopanda maburashi?”

III. Mwala Wapangodya wa Ntchito Zamalonda: N’chifukwa Chiyani Ma AC Motors Amapirira?

Malo ochitira masewera olimbitsa thupi amalonda, malo ochitira masewera olimbitsa thupi ku hotelo, ndi malo ochitira masewera olimbitsa thupi kusukulu amagwiritsa ntchito makina opumira a AC motor.Chifukwa chiyani?

Chifukwa amakwaniritsa zofunikira zitatu zofunika kwambiri pamakampani:

Kulimba ndi kudalirika. Ma mota a AC ali ndi kapangidwe kosavuta kopanda ma burashi a carbon omwe ali pachiwopsezo, omwe amasonyeza kuthekera kwapadera kopirira kugwira ntchito kwa nthawi yayitali, katundu wambiri komanso kuyambika/kuyima pafupipafupi. Moto wa AC wamalonda woyenererar iyenera kugwira ntchito modalirika kwa zaka 8-10 ndi kukonzedwa bwino.

Mphamvu Yogwira Ntchito Yokhazikika. Zipangizo zamalonda zimaika patsogolo "Continuous Horsepower" (CHP) kuposa mphamvu yapamwamba kwambiri ya akavalo. Ma mota a AC amapereka mphamvu yokhazikika pamlingo wovomerezeka kwa nthawi yayitali popanda kuchepetsa liwiro chifukwa cha kutentha kwambiri, zomwe zimapangitsa kuti ntchito iyende bwino ngakhale ogwiritsa ntchito olemera athamanga pa liwiro lalikulu.

Kuchepetsa ndalama zokonzera nthawi yayitali. Ngakhale kuti mtengo wogulira woyamba ndi wokwera, ma AC motors sali okonzedwanso. Kuchotsa mavuto ndi ndalama zosinthira maburashi ndi zowongolera za kaboni kumatanthauza kuti malo ochitira masewera olimbitsa thupi omwe amagwiritsa ntchito makina ambirimbiri asungidwa ndalama zambiri.

Kafukufuku wa Nkhani Zamakampani: Tinapereka njira zosinthira zida za kampani yolimbitsa thupi ku East China. Malo ena omwe anali m'malo mwawo anali atagula kale mitundu yamagetsi ya DC yamphamvu kwambiri kuti asunge bajeti. Pa nthawi ya makalasi a magulu ambiri, injini nthawi zambiri zinkatentha kwambiri ndikuzima, zomwe zinapangitsa kuti madandaulo a mamembala ayambe kuchuluka. Pambuyo posintha mayunitsi onse ndi mitundu yamagetsi ya AC yamalonda, matikiti okonzanso okhudzana ndi injini adachepa ndi kupitirira 90% mkati mwa zaka zitatu.

Funso Lofala kwa Ogwiritsa Ntchito: “Kodi ma mota a AC amalonda safuna mphamvu zambiri?” Izi ndi zolakwika. Pakadzaza mokwanira komanso kuthamanga kwambiri, ma mota a AC amagwira ntchito bwino kwambiri. Komabe, amagwiritsa ntchito mphamvu zambiri kuposa ma mota a DC panthawi yogwira ntchito mwachangu komanso nthawi yoyimirira. Komabe, m'malo amalonda omwe amagwiritsa ntchito zida zambiri—komwe makina amagwira ntchito kwambiri pamakina apakati mpaka okwera—mphamvu zawo zonse zimakhalabe zopikisana. Mtengo wamagetsi ndi wochepa poyerekeza ndi mtengo womwe umapezeka chifukwa cha kudalirika komanso kukhutira kwa mamembala.

IV. Buku Lotsogolera Zosankha Zogula: Kodi Mungasankhire Bwanji Magalimoto Kutengera Msika Wanu Wogulira?

Tsopano, tikhoza kukukonzerani njira yomveka bwino yopangira zisankho.

Ngati ndinu wogulitsa zinthu zambiri amene akuyang'ana kwambiri mabanja ogwiritsa ntchito zinthu zambiri:

Limbikitsani mitundu ya magalimoto a DC opanda burashi. Izi zikuyimira zomwe zikuchitika pamsika komanso mtsogolo. Tsindikani mfundo zazikulu zogulitsira: "ntchito yachete, kugwiritsa ntchito mphamvu moyenera, magwiridwe antchito abwino, komanso osakonza."

Lembani momveka bwino mphamvu ya horsepower yokhazikika (CHP). 1.5-2.5 CHP imakwaniritsa zosowa zambiri zapakhomo. Mphamvu ya horsepower yapamwamba ndi chiwerengero cha malonda chabe—musasocheretsedwe.

Perekani chitsimikizo cha mota chotalikirapo ngati chitsimikizo chapamwamba. Opanga omwe amapereka chitsimikizo cha zaka 5 kapena kuposerapo nthawi zambiri amagwiritsa ntchito zipangizo zolimba kwambiri.

Ngati mukufuna kugula zinthu zogwirira ntchito zamalonda (ma gym, mahotela, mabizinesi):

Ma mota a AC amalonda ndi ofunikira. Yang'anani kwambiri pa "mphamvu yopitilira" ya mota ndi gulu la insulation (makamaka Gulu F kapena kupitirira apo).

Unikani kapangidwe ka kuziziritsa kwa injini. Kuziziritsa mpweya bwino kapena chosungiramo chotenthetsera cha aluminiyamu ndikofunikira. Izi zimakhudza mwachindunji kukhazikika kwa ntchito kwa nthawi yayitali.

Muwunikireninso kafukufuku wa zamalonda wa ogulitsa ndi chithandizo chaukadaulo chokonza. Zipangizo zamalonda zimayang'ana kwambiri yankho lathunthu, osati makina okha.

Kumbukirani lamulo ili lapadera: Nyumba yogona imayang'ana kwambiri pa zomwe zikuchitika (ntchito chete, mawonekedwe anzeru); malonda amaika patsogolo kulimba (kulimba, mphamvu). Kugula zida zamalonda zokhala ndi miyezo ya nyumba kumabweretsa kuchuluka kwa zinthu; kugulitsa zinthu zamalonda kwa ogwiritsa ntchito nyumba kumachotsa kugwiritsa ntchito ndalama mopanda phindu.

Mapeto

Kusankha mtundu wa mota woyendera treadmill kumaphatikizapo kupeza bwino pakati pa mtengo woyambira, luso logwira ntchito, ndalama zosamalira, ndi moyo woyembekezeredwa. Ma mota a DC amalamulira msika wapakhomo chifukwa cha bata lawo lapamwamba, kuwongolera liwiro, komanso kugwiritsa ntchito mphamvu moyenera. Pakadali pano, ma mota a AC amagwira ntchito ngati maziko a ntchito zamalonda okhala ndi kudalirika kosayerekezeka komanso mphamvu yokhazikika. Monga wopanga zisankho zogula, kumvetsetsa bwino kusiyana kwakukulu ndi momwe mungagwiritsire ntchito moyenera mitundu iwiriyi ya magalimoto oyendera treadmill ndi sitepe yofunika kwambiri kuti mupewe misampha, kukulitsa kukhutitsidwa kwa makasitomala, ndikuwonjezera magwiridwe antchito.

FAQ

Q: Kodi ndiyenera kuyang'ana kwambiri pa “Continuous Horsepower (CHP)” ya injini kapena “Peak Horsepower (HP)”?

A: Nthawi zonse muziika patsogolo Mphamvu Yosalekeza ya Horsepower (CHP). Izi zikuwonetsa mphamvu yeniyeni ya injini kuti igwire ntchito bwino komanso mokhazikika kwa nthawi yayitali. Mphamvu Yokwera ya Horsepower imayimira mphamvu yayikulu yokha yomwe ingatheke kwakanthawi kochepa ndipo imakhala ndi phindu lochepa. Pakugwiritsa ntchito kunyumba, gwiritsani ntchito CHP yosachepera 1.5; mitundu yamalonda iyenera kupitirira 3.0 CHP kutengera mphamvu yogwiritsidwa ntchito.

Q: Ndi iti yabwino kuposa iyi: ma mota a DC opanda brushless kapena ma mota a AC variable-speed?

A: Zonse ziwiri zikuyimira ukadaulo wapamwamba. Ma mota a DC opanda maburashi amapereka magwiridwe antchito apamwamba kwambiri (ntchito chete, magwiridwe antchito, kuwongolera) m'nyumba. Ma mota a AC variable-speed amagwiritsidwa ntchito kwambiri m'magalimoto apamwamba kapena amalonda opepuka, kuphatikiza kulimba kwa ma mota a AC ndi kuwongolera liwiro kosalala kwa ma drive a frequency osinthasintha, koma amabwera pamtengo wapamwamba kwambiri. Kwa ogwiritsa ntchito ambiri apakhomo, mota ya DC yopanda maburashi yapamwamba ndiyo chisankho chabwino kwambiri komanso chokwanira.

Q: Kodi injini zamakampani kapena zapakhomo ziyenera kugwiritsidwa ntchito pa makina opumira mpweya m'chipinda cha alendo ku hotelo?

Yankho: Izi zimagwera pansi pa kugwiritsidwa ntchito kwa "malonda opepuka"—pafupipafupi kuposa m'nyumba koma kotsika kuposa m'malo ochitira masewera olimbitsa thupi akatswiri. Sankhani mitundu yopepuka yamalonda yokhala ndi mapangidwe a injini za AC zamalonda kapena mitundu yapamwamba ya DC yopanda burashi (onetsetsani kuti mphamvu yokwanira ikugwira ntchito komanso kapangidwe ka kutentha sikuchepa). Ikani patsogolo kuchuluka kwa kulephera kochepa komanso kugwira ntchito chete kuti mupewe madandaulo a alendo.
