Ngokwesimo somzimba, i-motor kagesi yinto eguqula amandla ukuthi ahambise uhlobo oluthile lwengxenye yomshini, kungaba imoto, iphrinta.Uma injini iyeka ukujikeleza ngesikhathi esifanayo, umhlaba ubungeke uwucabange.
Izinjini zikagesi zitholakala yonke indawo emphakathini wanamuhla, futhi onjiniyela bakhiqize izinhlobo eziningi zamamotho phakathi namakhulu eminyaka.
Izinjini eziningi zingama-actuator, okusho ukuthi ngokusebenzisa i-torque, zidala ukunyakaza.Isikhathi eside, amandla okushayela nge-hydraulic amadrayivu we-hydraulic ayeyindinganiso yangaleso sikhathi.Kodwa-ke, lolu hlobo lwezinjini luyanda ngekhulu lama-21 ngokuthuthuka kwamadrayivu kagesi, okuhambisana neqiniso lokuthi amandla kagesi abe maningi futhi kulula ukuwalawula.Kokubili, ingabe oyedwa ungcono kunomunye?Noma lokhu kuncike esimweni.
Uhlolojikelele lwamasistimu we-hydraulic
Uma uke wasebenzisa ujeke waphansi, noma washayela imoto enamabhuleki anamandla noma isiteringi samandla, ungase umangale ukuthi ungakwazi ukususa inani elikhulu kangaka lezinto ngaphandle kokusebenzisa amandla amaningi.(Ngakolunye uhlangothi, kungenzeka ukuthi udliwe kakhulu umsebenzi wokushintsha isondo eceleni komgwaqo ukuze ucabangele le micabango.)
Le misebenzi neminye efana nayo yenziwa yenzeke ngokusetshenziswa kwamasistimu asebenzisa amanzi amaningi.I-hydraulic system ayiwakhi amandla, kodwa kunalokho iyawaguqula isuka emthonjeni wangaphandle iwayise efomini elidingekayo.
Ucwaningo lwama-hydraulics luhlanganisa izindawo ezimbili eziyinhloko.AmaHydraulics ukusetshenziswa koketshezi ukwenza umsebenzi ngamanani agelezayo aphezulu kanye nengcindezi ephansi.Izigayo “zakudala” zisebenzisa amandla okugeleza kwamanzi ukuze zigaye okusanhlamvu.Ngokuphambene, i-hydrostatics isebenzisa umfutho ophezulu kanye noketshezi oluphansi lwamanzi ukwenza umsebenzi.Ngolimi lwefiziksi, siyini isisekelo salokhu kuhwebelana?
Amandla, Umsebenzi kanye nesikhala
Isisekelo esingokomzimba sokusebenzisa ama-hydraulic motors umqondo wokuphindaphinda ngamandla.Inani lengqikithi ohlelweni liwumkhiqizo wamandla engqikithi asetshenzisiwe kanye nebanga elinyakaziswa kungekho sibalo Wnet = (Fnet)(d).Lokhu kusho ukuthi ngomthwalo womsebenzi owabelwe umsebenzi womzimba, amandla adingekayo ukuze asetshenziswe angancishiswa ngokwandisa ibanga ekusetshenzisweni kwamandla, njengokujika kwesikulufu.
Lo mgomo unwebeka ngokomugqa uye kuzigcawu ezinezinhlangothi ezimbili ukusuka kubudlelwano p=F/A, lapho u-p=pressure ku-N/m2, F=force ku-Newtons, kanye no-A=indawo ku-m2.Kusistimu ye-hydraulic lapho i-pressure p igcinwa ingashintshi, kukhona ama-piston-cylinder amabili anezindawo eziphambanayo i-A1 ne-A2 eziholela kulobu budlelwano.F1/A1 = F2/A2, noma F1 = (A1/A2)F2.
Lokhu kusho ukuthi uma i-piston ephumayo engu-A2 inkulu kune-piston yokufaka i-A1, amandla okufaka azoba mancane ngokulinganayo kunamandla okukhiphayo.
Amamotho kagesi asebenzisa iqiniso lokuthi insimu kazibuthe yenza ingcindezi kushaje enyakazayo noma yamanje.Ikhoyili ejikelezayo yocingo ibekwa phakathi kwezigxobo zikazibuthe kagesi ukuze indawo kazibuthe yakhe itorque ebangela ikhoyili ukuthi ijikelezise ku-eksisi yayo.Le shaft ingasetshenziselwa izinto eziningi, futhi, ngamafuphi, injini iguqula amandla kagesi abe amandla emishini.
I-Hydraulics vs Electric Motors: Izinzuzo kanye Nokubi
Kungani usebenzise injini enamanzi, injini evuthayo yangaphakathi noma injini kagesi?Izinzuzo nezinkinga zohlobo ngalunye lwemoto ziningi kangangokuthi kufanele zicatshangelwe esimweni ngasinye esiyingqayizivele.
Izinzuzo zama-hydraulic motors
Inzuzo enkulu yama-hydraulic motors ukuthi angasetshenziswa ukukhiqiza amandla aphezulu kakhulu.
Ama-hydraulic motors asebenzisa uketshezi olungacindezeleki, oluvumela ukulawula okuqinile kwenjini futhi ngaleyo ndlela kube nokunemba okukhulu ekuhambeni.Phakathi kwemishini ephathwayo esindayo, iwusizo kakhulu.
Ukungalungi kwama-hydraulic motors
Ama-Hydraulic motors nawo ayindlela ebizayo, wonke uwoyela asetshenziswa, ukwenza lokhu kabi impela, izihlungi ezahlukahlukene, amaphampu namafutha adinga ukubhekwa, kushintshwe, kuhlanzwe, futhi kushintshwe.Ukuchithwa kungadala ukuphepha kanye nezingozi zemvelo.
Izinzuzo motor
Ukuvulwa kwe-hydraulic motor akusheshi kakhulu, i-motor ishesha kakhulu (kufika ku-10m / s).Banezivinini ezihlelekayo kanye nezikhundla zokumisa, ngokungafani namamotho asebenza ngogesi, anganikeza ukuma okunembayo okuphezulu okudingekayo.Izinzwa ze-elekthronikhi ziyakwazi ukunikeza impendulo enembile ngokunyakaza kanye namandla asetshenzisiwe.
Ukungalungi kwezinjini
Lawa ma-motor ayinkimbinkimbi futhi anzima ukuwafaka uma kuqhathaniswa namanye ama-motor, futhi ajwayele ukwehluleka kakhulu uma kuqhathaniswa namanye ama-motor.Iningi labo, okubi ukuthi udinga amandla amaningi, udinga injini enkulu futhi esindayo, ngokungafani nama-hydraulic motors.
Isingeniso ku-Pneumatic Drives
Ama-actuator e-pneumatic, electronic, noma hydraulic angaba yinkinga ezimeni ezithile.Umehluko phakathi kwe-pneumatic actuators kanye ne-hydraulic actuators ukuthi ama-hydraulic motors asebenzisa ukugeleza kwamanzi kuyilapho ama-actuator womoya esebenzisa igesi, ngokuvamile igesi evamile.
Amadrayivu e-pneumatic anenzuzo lapho kunomoya omningi, ngakho-ke i-compressor yegesi iyadingeka kuqala.Ngakolunye uhlangothi, lawa ma-motor awasebenzi kahle ngoba ukulahlekelwa ukushisa kukhulu kakhulu uma kuqhathaniswa nezinye izinhlobo zama-motor.
