Kwimisebenzi yoomatshini nezixhobo zoshishino, ioyile ye-hydraulic kunye nolwelo lokuthambisa ludlala indima ebalulekileyo "njengegazi lobomi" - ukuqinisekisa ukudluliselwa kwamandla okuhamba kakuhle, ukunciphisa ukungqubana phakathi kwezinto ezihambayo, kunye nokwandisa ubomi benkonzo yezinto zoomatshini. Ukulinganiswa ngokuchanekileyo kwamazinga okuhamba kwazo akusiyo nje into yokujonga ukusebenza kodwa yintsika yokugcinwa kwezixhobo, ukusebenza kakuhle kwamandla, kunye nokulawula iindleko. Phakathi kweendlela ezahlukeneyo zokulinganisa ukuhamba kwamanzi ezikhoyo, iimitha zokuhamba kwegiya ziye zavela njengokhetho olukhethwayo lweoyile ye-hydraulic kunye nolwelo lokuthambisa, ngenxa yokuchaneka kwazo okugqwesileyo, ukomelela, kunye nokuzivumelanisa neempawu ezizodwa zezi fluids.
Iimitha zokuhamba kwegiya ziphantsi kodidi lwemitha yokuhamba kakuhle, ezisebenza ngomgaqo olula kodwa osebenzayo kakhulu. Ngaphakathi kwendlu yemitha, iigiya ezimbini okanye ngaphezulu ezidibeneyo ziyajikeleza njengoko ulwelo ludlula kwigumbi. Ukujikeleza ngakunye kweegiya kususa umthamo omiselweyo wolwelo, kwaye inani lokujikeleza—elirekhodwe ngeenzwa (zoomatshini okanye ze-elektroniki)—liguqulwa libe kukufundwa kwesantya sokuhamba esichanekileyo. Le ndlela yokuhamba kakuhle inikezela ngeenzuzo ezisisiseko zeoyile ye-hydraulic kunye nolwelo lokuthambisa, oluhlala lubonisa ubushushu obuphezulu, amaqondo obushushu ahlukeneyo, kwaye luqulathe ungcoliseko oluncinci. Ngokungafaniyo neemitha zokuhamba ezisekelwe kwisantya (ezifana neemitha ze-turbine okanye ze-ultrasonic), iimitha zokuhamba kwegiya azichaphazeleki kangako lutshintsho lwe-viscosity yolwelo, ziqinisekisa ukuchaneka okuhlala kunjalo nangona zisebenza nolwelo oluqala kumanqanaba aphantsi ukuya kwaphezulu e-viscosity asetyenziswa rhoqo kwiinkqubo ze-hydraulic kunye neesekethe zokuthambisa.
Esinye sezizathu eziphambili zokuba iimitha zokuhamba kwegiya zigqwese kumlinganiselo weoyile ye-hydraulic kunye nolwelo lokuthambisa kukukwazi kwazo ukujongana neemeko ezinzima zeendawo zoshishino. Iinkqubo ze-hydraulic zihlala zisebenza kuxinzelelo oluphezulu (oluhlala ludlula iibha ezingama-300) kunye namaqondo obushushu, ngelixa ulwelo lokuthambisa lunokujikeleza ngemibhobho eqinileyo kunye neesekethe ezintsonkothileyo. Iimitha zokuhamba kwegiya zodidi lweshishini zenziwe ngezinto ezihlala ixesha elide ezifana nentsimbi engatyiwayo, iintsimbi ze-alloy eziqinileyo, okanye iipolymers ezingamelani nokugqwala, ukuqinisekisa ukuba zinokumelana noxinzelelo oluphezulu, ukuguquguquka kobushushu, kunye nohlobo lokurhawuzelela kolwelo oluthile lokuthambisa. Ukunyamezelana okuqinileyo kwimveliso yegiya kunciphisa ukuvuza kwangaphakathi, kuphucula ngakumbi ukuchaneka kokulinganisa—kubalulekile kwizicelo apho nokuba ukuphambuka okuncinci kwisantya sokuhamba kunokukhokelela ekungasebenzi kakuhle kwezixhobo okanye ekugugeni kwangethuba. Umzekelo, kumatshini wokwakha (njengee-excavators kunye nee-cranes), ukulinganisa okuchanekileyo ukuhamba kweoyile ye-hydraulic kunceda ukuphucula ukusasazwa kwamandla, ukuthintela ukugcwala kakhulu kweepompo ze-hydraulic kunye nokunciphisa ukusetyenziswa kwepetroli. Kwizakhiwo zokuvelisa, idatha echanekileyo yokuhamba kolwelo lokuthambisa iqinisekisa ukuba iibheringi, iigiya, kunye nezinye izinto ezibalulekileyo zifumana ubungakanani obuchanekileyo bokuthambisa obufunekayo, kuthintelwe ukuthambisa okungaphelelanga (okubangela ukungqubana nokushisa kakhulu) kunye nokuthambisa okugqithisileyo (okuchitha ulwelo kwaye konyuse iindleko zokulungisa).
Enye inzuzo yeemitha zokuhamba kwegiya kukuhambelana kwazo neempawu ezizodwa zeoyile ye-hydraulic kunye nee-lubricating fluids. Ezi fluids zihlala ziqulathe izongezo (ezifana nee-anti-wear agents, i-corrosion inhibitors, kunye ne-viscosity index improvers) ezinokuchaphazela ukusebenza kwezinye izixhobo zokulinganisa ukuhamba. Nangona kunjalo, iimitha zokuhamba kwegiya zinonxibelelwano oluncinci ne-fluid chemistry—umgaqo wazo wokulinganisa uxhomekeke ekufudukeni koomatshini kuneempawu zolwelo ezifana ne-conductivity okanye i-acoustic impedance. Oku kuzenza zilungele iintlobo ezahlukeneyo zeoyile ye-hydraulic (kubandakanya ii-mineral oil-based, synthetic, kunye ne-biobold hydraulic fluids) kunye nee-lubricating fluids (ezifana neoyile yemoto, ioyile yegiya, kunye ne-grease). Ukongeza, iimitha zokuhamba kwegiya zinokusebenza ngokufanelekileyo ngee-fluids eziqulethe ii-particles ezincinci (umz., ii-metal shavings ezincinci okanye uthuli), lo gama nje ii-particles zingekho nkulu ngokwaneleyo ukuba zivale ii-gears—imeko eqhelekileyo kwiindawo zoshishino apho ungcoliseko lolwelo ngamanye amaxesha lungenakuphepheka.
Ngokuphathelele ukufakwa kunye nokusetyenziswa, iimitha zokuhamba kwegiya zibonelela ngokuguquguquka okukhulu, okwenza kube lula ukuzidibanisa kwiinkqubo ze-hydraulic kunye ne-lubrication ezikhoyo. Zingafakwa kwiipayipi ezithe tye okanye ezithe nkqo, kunye neemfuno ezincinci zepayipi ezithe tye—ngokungafaniyo nezinye iimitha zokuhamba ezifuna ukuqhutywa kwepayipi ende phezulu nasezantsi ukuqinisekisa ukufundwa okuchanekileyo. Olu yilo oluncinci luluncedo ngakumbi kumatshini oshishino apho indawo incinci khona. Iimitha zokuhamba kwegiya zanamhlanje nazo zixhotyiswe ngeendlela ezahlukeneyo zokukhupha, kubandakanya imiqondiso ye-analog (4-20 mA), imiqondiso yedijithali (RS485, Modbus), kunye neziphumo ze-pulse, ezivumela ukuhlanganiswa okungenamthungo neenkqubo zolawulo, ii-data loggers, kunye nesoftware yokubeka esweni. Oku kwenza ukuba kulandelelwe izinga lokuhamba ngexesha langempela, ukujonga kude, kunye nezilumkiso ezenzekelayo zeemeko zokuhamba ezingaqhelekanga—ezifana nokuhamba okuphantsi (okubonisa ukuvuza okanye ukuvaleka okunokwenzeka) okanye ukuhamba okuphezulu (okubonisa ukungasebenzi kakuhle kwenkqubo). Kumaqela olondolozo, le datha ibaluleke kakhulu: ivumela ukusombulula iingxaki ngokukhawuleza, inciphisa ixesha lokungasebenzi, kwaye yandisa ubomi bemitha yokuhamba kunye nezixhobo ezizijongayo.
Xa ukhetha imitha yokuhamba kwegiya yokulinganisa ioyile ye-hydraulic kunye nomlinganiselo wolwelo lokuthambisa, kufuneka kuqwalaselwe izinto ezibalulekileyo ukuqinisekisa ukusebenza kakuhle. Okokuqala, uluhlu lokuhamba kwemitha kufuneka luhambelane neemfuno zesicelo—uluhlu oluncinci kakhulu luya kubangela ukugqithisa kakhulu, ngelixa uluhlu olukhulu kakhulu luya kuphazamisa ukuchaneka. Okwesibini, umlinganiselo woxinzelelo kunye nobushushu kufuneka udlule kwiimeko zokusebenza eziphezulu zenkqubo ukuthintela umonakalo. Okwesithathu, ukuhambelana kwezinto kubalulekile: kwiincindi ezirhabaxa okanye kwiindawo ezirhabaxa, kucetyiswa iimitha ezenziwe ngentsimbi engagqwaliyo okanye ii-alloys ezikhethekileyo. Okwesine, uhlobo lwesensor (yoomatshini okanye ye-elektroniki) kufuneka lukhethwe ngokusekelwe kwimfuno yokuchaneka, ukukhutshwa kwedatha, kunye neemfuno zokugcinwa—izinzwa ze-elektroniki zibonelela ngokuchaneka okuphezulu kunye nokuhlanganiswa kwedijithali, ngelixa izinzwa ze-mechanical zihlala zingabizi kakhulu kwaye zifuna ukugcinwa okuncinci. Okokugqibela, kufuneka kuqwalaselwe amaxesha okulinganisa: ukulinganiswa rhoqo (ngesiqhelo ngonyaka) kuqinisekisa ukuba imitha igcina ukuchaneka kwayo ngokuhamba kwexesha, ingakumbi kwizicelo ezifunwa kakhulu.
Ukuqukumbela, iimitha zokuhamba kwegiya zibonakala njengesisombululo esifanelekileyo sokulinganisa ioyile ye-hydraulic kunye nolwelo lokuthambisa kwiindawo zoshishino. Uyilo lwazo oluhle lokufuduka lubonelela ngokuchanekileyo okungenakuthelekiswa nanto, nokuba zinolwelo olunamandla aphezulu kunye neemeko zokusebenza ezahlukeneyo. Ulwakhiwo lwazo oluqinileyo luqinisekisa ukuqina nokuthembeka kwiindawo zoshishino ezinzima, ngelixa ukuhambelana kwazo neentlobo ezahlukeneyo zolwelo kunye nokufakelwa okulula kuzenza zibe nobuchule kwaye zibe lula ukuyisebenzisa. Ngokubonelela ngedatha echanekileyo, yexesha langempela, iimitha zokuhamba kwegiya zivumela amashishini ukuba aphucule ukusebenza kwezixhobo, anciphise iindleko zokulungisa, aphucule ukusebenza kakuhle kwamandla, kwaye athintele ixesha lokungasebenzi elibizayo. Kumashishini aqala kumveliso nokwakha ukuya kwiimoto kunye neenqwelo-moya, ukutyala imali kwimitha yokuhamba kwegiya esemgangathweni ophezulu akusiyonto yokulinganisa nje—sisigqibo esicwangcisiweyo esiphucula ukusebenza kakuhle kunye nokukhuphisana kwimeko-bume yanamhlanje yezoshishino ezifuna kakhulu. Njengoko ubuchwepheshe buqhubela phambili, iimitha zokuhamba kwegiya ziyaqhubeka nokukhula, ngezixhobo eziphuculweyo, izinzwa ezikrelekrele, kunye nokunxibelelana okuphuculweyo, okuqinisa ngakumbi isikhundla sazo njengokhetho oluphambili lweoyile ye-hydraulic kunye nolwelo lokuthambisa.
