Ngokwasemzimbeni, i-motor yombane yinto eguqula amandla ekuhambiseni uhlobo oluthile lomatshini, nokuba yimoto, umshicileli.Ukuba i-motor iyeka ukujikeleza kwangaxeshanye, umhlaba ngewungenakucingelwa.
Iinjini zombane zikho kuyo yonke indawo kuluntu lwale mihla, kwaye iinjineli ziye zavelisa iintlobo ezininzi zeenjini ukutyhubela iinkulungwane.
Iinjini ezininzi zi-actuator, oku kuthetha ukuba ngokusetyenziswa kwetorque, zenza intshukumo.Ixesha elide, amandla okuqhuba i-hydraulic ye-hydraulic drives yayingumgangatho wexesha.Nangona kunjalo, olu hlobo lweemoto luyanda kwinkulungwane yama-21 kunye nenkqubela phambili yombane wokuqhuba, udityaniswa nento yokuba amandla ombane aye maninzi kwaye kulula ukuwalawula.Kwezi zibini, ngaba omnye ulunge ngakumbi kunomnye?Okanye oku kuxhomekeke kwimeko.
Isishwankathelo seenkqubo zamanzi
Ukuba ukhe wasebenzisa ijekhi yomgangatho, okanye uqhube isithuthi esineziqhoboshi zamandla okanye i-power steering, unokumangaliswa kukuba unokuhambisa inani elikhulu kangaka lezinto ngaphandle kokuchitha amandla amaninzi.(Ngakwelinye icala, usenokuba uxakeke kakhulu ngumsebenzi wokutshintsha itayara ecaleni kwendlela ukuze uqwalasele ezi ngcinga.)
Le misebenzi kunye neminye efana nayo yenziwa yenzeke ngokusetyenziswa kweenkqubo zoxinzelelo lwamanzi.Inkqubo ye-hydraulic ayidali amandla, kodwa endaweni yoko iguqulela kumthombo wangaphandle kwifom efunekayo.
Uphononongo lwe-hydraulics lubandakanya iindawo ezimbini eziphambili.I-Hydraulics kukusetyenziswa kwamanzi ukwenza umsebenzi kumazinga aphezulu okuhamba kunye noxinzelelo oluphantsi.Izingqusho “zakudala” zisebenzisa amandla okuqukuqela kwamanzi ukuze zisile iinkozo.Ngokwahlukileyo, i-hydrostatics isebenzisa uxinzelelo oluphezulu kunye nolwelo oluphantsi lwamanzi ukwenza umsebenzi.Ngolwimi lwefiziksi, yintoni isiseko solu rhwebo?
Amandla, uMsebenzi kunye neNdawo
Isiseko somzimba sokusebenzisa iimotor zehydraulic ngumbono wokuphindaphinda kwamandla.Ixabiso le-net kwisixokelelwano yimveliso ye-net force esetyenzisiweyo kunye nomgama ohanjiswe ngaphandle komfanekiso Wnet = (Fnet) (d).Oku kuthetha ukuba umthwalo womsebenzi owabelwe umsebenzi womzimba, amandla afunekayo ukuba asetyenziswe angancitshiswa ngokunyusa umgama kwisicelo samandla, njengokujika kwe-screw.
Lo mgaqo unabela ngokulandelelana ukuya kwimiboniso enemigangatho emibini ukusuka kunxulumano p=F/A, apho p=uxinzelelo kwi-N/m2, F=force kwi-Newtons, kunye no-A=indawo kwi-m2.Kwinkqubo ye-hydraulic apho uxinzelelo lwe-p lugcinwa rhoqo, kukho iisilinda ezimbini ze-piston ezineendawo ezinqamlezileyo ze-A1 kunye ne-A2 ezikhokelela kulo budlelwane.F1/A1 = F2/A2, okanye F1 = (A1/A2)F2.
Oku kuthetha ukuba xa i-piston ephumayo i-A2 inkulu kune-piston yokufakelwa kwe-A1, amandla okufakwayo aya kuba ncinane ngokomlinganiselo kunamandla aphumayo.
Iimoto zombane zithatha ithuba lokuba intsimi yamagnetic yenza uxinzelelo kwintlawulo ehambayo okanye yangoku.Ikhoyili ejikelezayo yocingo ibekwe phakathi kweepali ze-electromagnetic field ukuze imagnethi idale i-torque ebangela ukuba ikhoyili ijikeleze malunga ne-axis yayo.Le shaft ingasetyenziselwa izinto ezininzi, kwaye, ngokufutshane, i-motor iguqula amandla ombane abe ngamandla oomatshini.
I-Hydraulics vs Motors zoMbane: Izinto eziluncedo kunye nokungahambi kakuhle
Kutheni usebenzisa i-hydraulic motor, injini yokutsha yangaphakathi okanye injini yombane?Iingenelo kunye nokungalunganga kohlobo ngalunye lwemoto zininzi kangangokuba zifanelekile ukuqwalaselwa kwimeko nganye ekhethekileyo.
Izinto ezilungileyo zeenjini zehydraulic
Olona ncedo luphambili lweenjini zehydraulic kukuba zinokusetyenziselwa ukuvelisa amandla aphezulu kakhulu.
Iinjini zeHydraulic zisebenzisa ulwelo olungangqinelaniyo, oluvumela ulawulo olungqongqo lwemoto kwaye ngaloo ndlela ukuchaneka okukhulu kwintshukumo.Phakathi kwezixhobo eziphathwayo ezinzima, ziluncedo kakhulu.
Ukungalungi kweenjini ze-hydraulic
Iinjini zeHydraulic zikwalukhetho olubiza kakhulu, yonke ioyile iyasebenza, ukwenza oku kubi kakhulu, izihluzi ezahlukeneyo, iimpompo kunye neeoyile kufuneka zijongwe, zitshintshwe, zicocwe, zitshintshwe.Ukuchitheka kungadala ukhuseleko kunye neengozi zokusingqongileyo.
Izinto ezilungileyo zemoto
Ukuvulwa kwemoto ye-hydraulic ayikhawulezi kakhulu, i-motor ikhawuleza kakhulu (ukuya kwi-10m / s).Banezantya ezicwangcisiweyo kunye neendawo zokumisa, ngokungafaniyo neenjini ze-hydraulic, ezinokubonelela ngeendawo eziphezulu ezifunekayo ezichanekileyo.Iinzwa ze-elektroniki ziyakwazi ukubonelela ngengxelo echanekileyo malunga nokunyakaza kunye nokusebenza kwamandla.
Ukungalungi kweenjini
Ezi njini zintsonkothile kwaye kunzima ukuzifaka xa kuthelekiswa nezinye iinjini, kwaye zithande ukusilela kakhulu xa zithelekiswa nezinye iinjini.Uninzi lwazo, into engalunganga kukuba ufuna amandla angaphezulu, udinga i-motor enkulu kunye nobunzima, ngokungafaniyo neenjini zehydraulic.
Intshayelelo kwi-Pneumatic Drives
I-pneumatic, electronic, okanye i-hydraulic actuators inokuba yingxaki kwiimeko ezithile.Umahluko phakathi kwe-pneumatic kunye ne-hydraulic actuators kukuba iimotor ze-hydraulic zisebenzisa ukuhamba kwamanzi ngelixa ii-actuator ze-pneumatic zisebenzisa igesi, ngokuqhelekileyo igesi eqhelekileyo.
Ukuqhuba kwe-pneumatic kunenzuzo apho umoya uninzi, ngoko ke i-compressor yegesi kufuneka kuqala.Kwelinye icala, ezi motor azisebenzi kakhulu kuba ilahleko yobushushu inkulu kakhulu xa kuthelekiswa nezinye iintlobo zeenjini.
