Ukuqhathaniswa Kwesakhiwo: Ama-Vane Motors vs. Ama-Gear Motors

Indlela Imoto Ye-Vane Esebenza Ngayo

Injini ye-hydraulic vane isebenzisa i-rotor enezikhala efakwe emgodini ojikelezayo (indandatho ye-cam). I-rotor ifakwe ngendlela engavamile - okusho ukuthi ayihlali phakathi nendawo yendlu. Uketshezi lwe-hydraulic olungena ngaphansi kwengcindezi luphoqa ama-vane - ngokuvamile angu-7 kuya kwangu-12 ngenjini ngayinye kuye ngomklamo - luphuma ngomsindo ngokumelene nendandatho ye-cam, okudala umugqa wokuvala phakathi kwesihloko ngasinye se-vane nodonga lwangaphakathi lwendlu.

Njengoba i-rotor iphenduka, ama-vane ayashelela angene futhi aphume ezindaweni zawo. I-vane ngayinye idala igumbi lokucindezela elihlukile elixhumanisa ngokushintshana kuma-port okungena nawokuphuma, okwenza i-torque. I-geometry yendandatho ye-cam inquma ukufuduka ngokujikeleza ngakunye. Ngenxa yokuthi ama-vane antanta efilimini yoketshezi lwe-hydraulic, ukuvala kuyashintshashintsha futhi kuyazenzela imali — njengoba kwenzeka ukuguguleka, ama-vane avele anwebeke ukuze agcine ukuxhumana.

Lo mklamo ukhiqiza izakhiwo eziningana ezihambisana ngqo nezinhlelo zokusebenza ze-conveyor drive:

• Isivinini esiphezulu sokujikeleza— ngokuvamile i-400 kuya ku-2,600 RPM kumamodeli ajwayelekile, kanti eminye imiklamo ifinyelela ku-4,000+ RPM. Lokhu kusho ukuthi injini ivame ukushayela i-conveyor ngqo ngaphandle kwe-gearbox ephakathi, okunciphisa ubunzima bemishini yesistimu yokushayela.
• Ukulethwa kwe-torque okubushelelezi— ukugoqana koketshezi phakathi kwama-vane kusho umsindo omncane kanye nokudlidliza okuncane uma kuqhathaniswa nokugoqa amagiya.
• Ukugqoka okuzikhokhelayo— njengoba ama-vane eguga, umugqa wokuvala uyashintsha esikhundleni sokuwohloka ngokuzumayo. Lokhu kunikeza ama-vane motors ijika kancane kancane ekusebenzeni kwawo.
• Umkhawulo we-torque wokuqala ophansi— ama-vane motors ngokuvamile angaqala ngaphansi komthwalo ngezingcindezi eziphansi kunezinjini zamagiya, okubalulekile ekuqaliseni kabusha kwe-conveyor ngemva kokususwa kwe-jam.

Indlela Injini Yegiya Esebenza Ngayo

Injini yegiya le-hydraulic isebenzisa amagiya amabili axhumene — igiya lokushayela kanye negiya elingasebenzi — agcinwe ekamelweni elinomshini oqondile. Uketshezi olungena echwebeni lokungena lubhajwe phakathi kwamazinyo egiya njengoba luhlangana ohlangothini lokungena, bese luhanjiswa luzungeze indlu luye ohlangothini lokungena lapho amazinyo ephuma khona, akhulule uketshezi futhi akhiqize i-torque.

Ubulula balo mklamo bubangelwa amandla awo kanye nobuthakathaka bawo. Njengoba inezingxenye ezimbili ezijikelezayo kuphela, ama-gear motor alula ngokwemishini futhi ashibhile ukuwakhiqiza. Afaneleka kahle izinhlelo zokusebenza ezidinga i-torque ephezulu yokuqala ngesivinini esiphansi. Kodwa-ke, eza nokushintshana okungokwemvelo:

• Isivinini esiphezulu esiphansi— ngokuvamile kusuka ku-400 kuya ku-1,800 RPM, okunciphisa ukucushwa kwe-direct-drive.
• imvume ezinzile— izimbobo zamazinyo egiya zibekwe lapho kuhlanganiswa futhi azikwazi ukuzilungisa. Njengoba ukuguguleka kuqhubeka, ukuvuza okudlule emaceleni egiya kuyanda, okubangela ukusebenza kahle kwevolumu.
• Ukuzwela okuphezulu ekungcoleni— amazinyo egiya asogwini oluseduze asebenza njengesicupho sezinhlayiya. I-fiber eyodwa ebanjwe phakathi kwezinhlangothi zegiya ingasheshisa ukuguguleka kulo lonke ubuso bezinyo.
• Ukusebenza kahle kwevolumu okuphansi ngaphansi komthwalo oguquguqukayo— ama-gear motors athola ukuvuza okukhulu kwe-bypass lapho esebenza kude nendawo yokucindezela yomklamo wawo.

Amajika Okusebenza Kahle: Indawo Ye-Torque Engu-60–80%

Kuma-drive okuhambisa umoba, indawo yokusebenza evamile iphakathi kuka-60% no-80% we-torque yemoto elinganisiwe ngesikhathi sokusebenza okuvamile — kanye neziqongo ezimfushane eziya ku-110% ngesikhathi semicimbi yokulayisha ngokweqile. Yilapho ama-curve okusebenza kahle kwama-vane nama-gear motor ehlukana khona ngokuphawulekayo.

Ama-gear motors avame ukufinyelela ukusebenza kahle kwe-volumetric eduze kwe-design pressure point yawo — ngokuvamile ama-bar angu-150 kuya kwangu-200 kumamodeli ezimboni anomfutho ophakathi. Nge-torque engu-60–80% (cishe ama-bar angu-100–150), i-gear motor ingase isebenze kahle nge-volumetric 82–87%. Endaweni efanayo yokusebenza, i-vane motor eklanywe kahle ivame ukugcina ukusebenza kahle kwe-volumetric okungu-88–93% ngenxa ye-self-sealing vane.

Esikhathini sokuvuna sezinyanga eziyisishiyagalombili esisebenza amahora angama-24 ngosuku, lesi sikhala sokusebenza kahle samaphesenti ama-5-6 sihumusha umehluko wokusetshenziswa kwamandla okunengqondo - ikakhulukazi esikalini somshini wokugaya ocubungula amathani ayi-12,000 ngosuku lapho amandla okushayela kokuthutha angadlula ama-kW angama-75 ngenjini ngayinye.

Kuma-mill asebenzisa ama-gear motor kuma-conveyor awo njengamanje, ukushintshela kuma-vane motors akuyona iphrojekthi yobunjiniyela eyinkimbinkimbi - kuyisimo sokushintshana ngqo kumasayizi amaningi ozimele ajwayelekile. Ukucushwa kwedrayivu ephindwe kabili okudingwa ama-conveyor amaningi amamitha angu-50 kungaphakathi kakhulu kobubanzi bekhono lamamodeli e-vane motor ajwayelekile, futhi ukuxhumana kwezintambo kanye ne-hydraulic kuyashintshana nemikhuba ejwayelekile yezimoto zezimboni.

Icala lokutshalwa kwezimali lisekelwe ekuqhathaniseni okulula: ukusetshenziswa kwemali yokulungisa yonyaka kanye nokuvezwa kwesikhathi sokungasebenzi ngama-gear motors, ngokumelene nezindleko ezifakiwe kanye nempilo yesevisi ngama-vane motors. Ngokwezinombolo engizibonile eSão Paulo mills, ama-vane motors azikhokhela zingakapheli izinyanga ezingu-18 kuya kwezingu-24 ngesicelo esijwayelekile sokushayela i-conveyor.

Uma uhlola lokhu ngomshini wakho wokugaya noma iphrojekthi osebenza kuyo, ngingayamukela ingxoxo eqondile yobuchwepheshe. Ithimba lethu lobunjiniyela kwaVicks Hydraulic lingakunikeza ukwesekwa kokukhetha injini ngokusekelwe ezicini zakho ezithile zokuhambisa, kufaka phakathi isivinini sebhande, iphrofayili yomthwalo, kanye nokucushwa kwedrayivu.
