Ama-operators eminyango eshelelayo asebenza kanzima alinganiswe ngamaphaneli eminyango angu-2x250kg anama-motor e-DC angenamabhulashi angu-24V/120W aletha ukuzenzekela okuthule, okuthembekile, nokungalungi okudingwa yizindawo zokulayisha impahla ezithwala abantu abaningi usuku nosuku.

Kungani Izindawo Zokulayisha Izimpahla Ziyisivivinyo Esinzima Kakhulu Kubasebenzi Beminyango

Umnyango wegumbi lokulayisha impahla esikhungweni sokusabalalisa esimatasa uvula futhi uvale izikhathi ezingu-200-400 ngosuku — okungukuthi imijikelezo engu-70,000 kuya ku-140,000 ngonyaka. Umjikelezo ngamunye ubeka umqhubi womnyango umthwalo ogcwele womshini: sheshisa iphaneli yomnyango kusukela ku-zero iye cishe kumamitha angu-0.3-0.5 ngomzuzwana, gcina isivinini esiqhubekayo ngesikhathi sokuhamba, yehlisa ijubane kahle uye kuma, futhi ubambe isikhundla ngokumelene nomfutho womoya, umehluko womfutho womoya ovela ezinhlelweni ze-HVAC, kanye nokugoba okungenakugwenywa okuvela kuthrafikhi ye-forklift. Iningi labasebenzi beminyango yezentengiselwano lenzelwe imijikelezo engu-20-50 ngosuku ezindaweni zokuthengisa noma zehhovisi. Beka enye yalezo endaweni yokulayisha impahla, futhi izohluleka zingakapheli izinyanga ezingu-6-12 — Ngikubonile lokhu kwenzeka izikhathi eziningi kakhulu kunalokho engingakubala.

Igama lami ngingu-Edison, futhi njengoMphathi Wezokuthengisa e-Ningbo Yufan Beifan Automatic Door Co., ngisebenza nabaphathi bezikhungo zezimboni, abahleli bezikhungo zezokuthutha, kanye nabahlanganisi bezinhlelo zeminyango emazweni angaphezu kuka-30 ukuze ngichaze abaqhubi beminyango abangasinda kulezi zindawo ezijezisayo. Incazelo eyodwa ehlukanisa umqhubi weminyango yezimboni ofanele kulowo ozoba yikhanda lokulungisa ubuchwepheshe bemoto - futhi ikakhulukazi, ukuthi imoto isebenzisa amabhulashi e-carbon ukushintsha noma ukulawula ngogesi. Umehluko empilweni yesevisi phakathi kwalezi zobuchwepheshe ezimbili ulinganiswa ngokuphindaphinda, hhayi ngamaphesenti, futhi uhumusha ngqo ezindlekweni eziphelele zobunikazi empilweni yesevisi yokwakha yomnyango yeminyaka engu-15-20.

Ngokombono wokuthobela imithetho, abaqhubi beminyango yezimboni abanzima kumele bahlangabezaneIzindinganiso zokuphepha zemishini ze-ISOyeminyango yabahamba ngezinyawo neyasezimbonini esebenza ngogesi, kanyeIziqondiso ze-SAE zokuzenzakalela kwezimboniezichaza ukulinganiselwa kwamandla, ukutholwa kokuvinjelwa, kanye nezidingo zokuphuma eziphuthumayo. I-voltage yokusebenza engu-24V yenza kube lula ukuhambisana neziqondiso zokuphepha ze-voltage ephansi kakhulu — uhlelo lwe-24V lungafakwa ngezindlela ezijwayelekile zokuxhuma izintambo ze-voltage ephansi kunekhebula elivikelwe kanye nomsele wensimbi odingekayo kubasebenzi beminyango ye-line-voltage.

Ama-Brushless vs. Brushed Motors: Isinqumo Sobuchwepheshe Esichaza Impilo Yesevisi

Umehluko oyinhloko phakathi kwama-motor e-DC axutshwe ne-brushless yilapho kwenzeka khona ukushintsha kukagesi — futhi ukuqonda lo mehluko kubalulekile kunoma ubani ochaza umqhubi womnyango wezinhlelo zokusebenza zezimboni ezihamba phambili. Kumoto exutshwe ne-brush, amabhulashi e-carbon acindezela i-commutator yethusi ejikelezayo ukuze ashintshe isiqondiso samanje kuma-windings e-rotor njengoba imoto iphenduka. Lokhu kuxhumana komshini kudala ukungqubuzana, ukujikeleza kukagesi phakathi kwezingxenye zebhulashi ne-commutator, kanye nokuguga okuqhubekayo — amabhulashi ayagaya ngokoqobo ngokujikeleza ngakunye, akhiqize uthuli lwekhabhoni olungcolisa izingxenye zangaphakathi zemoto. Imoto exutshwe ne-brush kumqhubi womnyango osebenzisa imijikelezo engu-80,000 ngonyaka ngokuvamile izodinga ukushintshwa kwebhulashi emahoreni angu-3,000-5,000, noma cishe njalo eminyakeni engu-2-3 esenkonzweni yokugcina impahla.

Injini ye-DC engenamabhulashi isusa amabhulashi kanye ne-commutator ngokuphelele ngokusebenzisa i-electronic commutation — i-microprocessor kusilawuli senjini ishintsha amandla kagesi ngokusebenzisa ama-stator windings ngokulandelana okunembile, idala insimu yamagnetic ejikelezayo edonsa i-rotor ene-magnet ehlala njalo. Akukho ukuthintana komshini, akukho ukungqubuzana, akukho arcing, akukho zinhlayiya ezigugile, futhi akukho ukungcoliswa kothuli lwekhabhoni. Izingxenye ezigugile kuphela ama-ball bearings avaliwe asekela i-rotor shaft, alinganiselwe amahora angu-20,000-30,000 ngemithwalo nesivinini esivamile sesevisi yomqhubi weminyango. Ngokwezwi elingokoqobo, injini engenamabhulashi efakwe kumqhubi weminyango yendlu yokugcina impahla namuhla izobe isasebenza kahle lapho iphaneli yomnyango ngokwayo ifinyelela ekupheleni kokuphila kwayo kwenkonzo futhi idinga ukushintshwa.

Incazelo ye-24V/120W ifanelwe incazelo ethile, ngoba ama-watts angu-120 abonakala elula ukuhambisa umnyango ongu-500 kg. Isihluthulelo yi-helical worm gear reducer ehlanganisiwe enesilinganiso esingu-15:1, eguqula i-3,000 RPM yemoto ibe yisivinini sokukhipha esingu-200 RPM esidingekayo ukuze kuhambe kahle umnyango. Ukunciphisa igiya kwandisa i-torque yemoto cishe izikhathi ezingu-12-14 (okubalwa ukusebenza kahle kwegiya okungu-85-90% kusethi yegiya le-worm), kuguqula i-torque engu-0.38 Nm yemoto engu-120W ibe cishe yi-4.5-5.0 Nm ku-shaft yokukhipha i-gearbox. Le torque yokukhipha, esetshenziswa ngegiya le-pinion elihlanganisa i-rack enamazinyo kuphaneli yomnyango, ikhiqiza amandla aqondile adingekayo ukusheshisa isisindo somnyango osakazekile esingu-500 kg ku-0.3 m/s square - ukusheshisa okubushelelezi nokulawulwayo okunciphisa ukuguguleka ohlelweni lonke lomnyango.

Umklamo wegiya eliyindilinga ngaphakathi kwebhokisi legiya unikeza inzuzo eyengeziwe ngale kokuphindaphinda kwe-torque: kunciphisa umsindo wokusebenza ngo-10-15 dB uma kuqhathaniswa nokudluliselwa kwegiya eliqondile le-spur. Endaweni yokulayisha impahla yokugcina impahla lapho umnyango usebenza khona izikhathi ezingu-300 ngosuku ngaphakathi kokuzwa kwabasebenzi bokuthumela nokwamukela, lokhu kunciphisa umsindo kuguqula umnyango usuke ekuphazamisekeni okuzwakalayo uye emsindweni wangemuva abasebenzi abayeka ukuwubona ngemva kwesonto lokuqala lokusebenza. Umklamo ohlanganisiwe - inzwa yesimo semoto, i-gearbox, kanye ne-Hall-effect endlini eyodwa enesilinganiso se-IP54 - futhi uqeda inqubo yokuvumelanisa phakathi kwezingxenye zemoto ezihlukene kanye nebhokisi legiya ebangela ingxenye enkulu yesikhathi sokufakwa ezinhlelweni ezivamile zomsebenzisi weminyango.

Ukusatshalaliswa Kwesisindo Sephaneli Yomnyango: Kungani I-2x250kg Ibalulekile Ekwakhiweni Kokufakwa

Ukucacisa umthamo womqhubi njengo-2x250kg esikhundleni sesibalo esisodwa esingu-500kg kubonisa ukucushwa kwangempela kweminyango eshelelayo yezimboni. Iningi leminyango ye-bay yokulayisha impahla yokugcina impahla isebenzisa ukucushwa kwe-biparting - amaphaneli amabili ashelelayo ahlukene phakathi - iphaneli ngayinye inesisindo esingu-200-300 kg futhi ikhwele isethi yayo yama-hanger rollers kanye nesigaba sayo sethrekhi yesakhiwo. Isilinganiso esingu-2x250kg sisho ukuthi umqhubi wenzelwe ukushayela womabili amaphaneli ngesikhathi esisodwa ngohlelo lokushayela ibhande oluvumelanisiwe, iphaneli ngayinye ifaka umthwalo ofinyelela ku-250 kg ekuxhumekeni kwayo kwethrekhi. Lokhu kucushwa okusatshalaliswe kunciphisa imithwalo yamaphuzu agxilile esakhiweni sesakhiwo, kuvumela ukusetshenziswa kwamaphrofayili ethrekhi yeminyango ejwayelekile, futhi kunikeza ukungasebenzi kahle - uma iphaneli eyodwa ivimbekile ngenxa yemfucumfucu ethrekhini, indlela ye-clutch isusa idrayivu yephaneli ngenkathi elinye iphaneli lingase lithuthwe ngesandla ukuze liphume ngokuphuthumayo.

Iphaneli evamile yomnyango wokufaka insimbi evalekile enobubanzi obungamamitha ama-3 namamitha ama-4 ukuphakama, eyakhiwe ngamaphaneli esandwich agcwele i-polyurethane obukhulu obungu-40mm futhi aqiniswe ngohlaka lwensimbi oluhlanganisiwe, inesisindo esingaba ngu-180-220 kg kuye ngesilinganiso sensimbi kanye nobuningi bokufaka insimbi. Amaphaneli amabili anjalo ahlelwe ngokwahlukana angama-360-440 kg, angaphakathi kwesilinganiso somsebenzi esingu-2x250kg kanye nomkhawulo womthwalo okhululekile ongu-10-28%. Lo mkhawulo uvumela umthwalo womoya (onezela amandla angu-200-300 N kuphaneli engu-12 m² emoyeni ongu-50 km/h), ukuqongelela okuncane kweqhwa ezindaweni ezibandayo, kanye nokwanda kancane kancane kokumelana nokugoqa njengoba ukugcotshwa komzila womnyango kuncipha phakathi kwezikhawu zokulungisa.Ikhathalogi yomqhubi weminyango ye-YFBFifaka amathebula okubala umthwalo anemininingwane ukuqinisekisa ukuthi ukucushwa kwephaneli yomnyango ethile, okuhlanganisa uhlobo lwethrekhi kanye nezimo zemvelo, kuwela ngaphakathi komthamo olinganiselwe womqhubi.

Izindlela Ezinhle Zokufaka Zabasebenzi Beminyango Enzima

Iphutha elilodwa elivame kakhulu lokufaka engihlangana nalo — futhi ngokusekelwe ezingcingweni zesevisi eziphathwa yithimba lethu losekelo lobuchwepheshe, libangela cishe u-35% wazo zonke izinkinga zangemuva kokufakwa — ukungezwani kwebhande okungafanele phakathi kwephini lokukhipha lomqhubi kanye ne-drive rack yephaneli yomnyango. Ibhande lesikhathi elidlulisela amandla kusuka kumqhubi liye emnyango kumele liqiniswe ngokwencazelo yomkhiqizi, okuthi kumqhubi we-YF150 kube yi-120-150 N yokuqina okungaguquki ebhandeni lephrofayili le-HTD elingu-15mm ububanzi. Amabhande angaphansi kokuqina aweqa amazinyo ngesikhathi sesigaba sokusheshisa, okubangela ukuthi umnyango uqhume, ume, noma ume phakathi nohambo — iphutha isilawuli somnyango elilichaza njengesiphazamiso, okubangela ukuguguleka okungadingekile. Amabhande aqinile kakhulu abeka imithwalo ye-radial eningi kakhulu kuma-shaft bearings okukhiphayo emoto, asheshise ukuguguleka kwama-bearings futhi angase anciphise impilo yesevisi ngo-50% noma ngaphezulu.

Ukuqina okulungile kungaqinisekiswa ngokuhlolwa okulula kokujika okungadingi mathuluzi akhethekile. Faka amandla angaba ngu-20 N (cishe isisindo sesisindo esingu-2 kg) endaweni ephakathi nendawo yebhande elide kakhulu elingasekelwa. Ibhande kufanele lijike libe ngu-8-10 mm ubude bebhande elingu-300 mm. Uma ukujika kudlula u-10 mm, yandisa ukuqina. Uma ukujika kungaphansi kuka-5 mm, yehlisa ukuqina. Lokhu kuhlola kwemizuzwana engama-30, okwenziwa ekufakweni futhi kwaqinisekiswa ngezikhathi zesevisi zezinyanga ezi-3 kanye nezinyanga eziyi-12, kuvimbela iningi lezinkinga zokusebenza ezihlobene nebhande.

Ukufakwa kukagesi kulula ngenxa ye-voltage yokusebenza engu-24V. Umqhubi udinga ugesi owodwa ongu-24V DC olinganiselwe ku-150W (ohlinzeka ngomkhawulo ongu-25% ngaphezu kokudonsa okuphezulu kwemoto okungu-120W), uxhumano ohlelweni lokulawula umnyango ngokusebenzisa okokufaka kokuxhumana okomile ukuze kulandelwe imiyalo yokuvula/ukuvala/ukumisa, kanye nokuxhuma kwisekethe yesensa yokuphepha — ama-photocell noma imiphetho yokuphepha ezwela ukucindezela ebona ukuvinjelwa futhi ibangele umjikelezo wokuma nokubuyela emuva ngokushesha. Ngenxa yokuthi konke kusebenza ku-24V, zonke izintambo zensimu zingasebenza kumsele ojwayelekile we-PVC noma ngisho namathreyi ekhebula avele, okususa isidingo somsele wensimbi, amabhokisi okuxhumanisa angangenisi isimo sezulu, kanye nokukhishwa kukagesi onelayisensi okudingwa ukufakwa komnyango we-line-voltage. Ekufakweni okuvamile kwe-4-door loading bay, ukonga izindleko zikagesi kusuka ekusebenzeni kwe-24V kuphela kuvame ukusuka ku-USD 800 kuya ku-USD 1,500 uma kuqhathaniswa nezinye izindlela ze-line-voltage.

imibuzo ejwayelekile ukubuzwa

Nginganquma kanjani ukuthi umqhubi womnyango ongu-2x250kg usayizi ofanele yini ngokwesimo sami esithile somnyango?

Bala isisindo esiphelele sokuhamba kwesistimu yakho yeminyango ngokufingqa isisindo sephaneli yomnyango (kusukela ezicacisweni zomkhiqizi noma ezibalwe kusukela kubukhulu bephaneli kanye nobuningi bezinto ezibonakalayo), isisindo sama-hanger rollers kanye nama-bracket okufaka (ngokuvamile ama-5-10 kg ngephaneli ngayinye), kanye nezibonelelo zomthwalo wemvelo. Ngeminyango yangaphandle, engeza u-10-15% wokucindezela komoya — iphaneli engu-3m ​​x 4m ku-50 km/h umoya uhlangabezana namandla engeziwe angu-200-300 N okumele anqotshwe ngumsebenzisi. Ekufakweni kwesimo sezulu esibandayo, engeza u-5% wokuqongelela kweqhwa okungenzeka.
