Kwinkqubo yemizi-mveliso yanamhlanje, inkqubo ye-hydraulic isetyenziswa kakhulu kwiindawo ezahlukeneyo ezifana noomatshini bokwakha, oomatshini bemigodi, kunye nokwakha iinqanawa ngenxa yeenzuzo zayo zokudlulisela amandla ngokufanelekileyo nangokuzinzileyo. Ivalvu yebhuleki, njengenxalenye ebalulekileyo yenkqubo ye-hydraulic, ayibalulekanga kangako.
1. Ukuqinisekisa ukhuseleko lokusebenza kwezixhobo
Izixhobo eziqhutywa yinkqubo ye-hydraulic zihlala zinemithwalo emikhulu kunye nesantya esiphezulu. Ukuba kwenzeka ingozi kwaye ukuqhobosha kungenziwa ngexesha, kusenokwenzeka ukuba kubangele iingozi ezinkulu zokhuseleko. Ivalvu yebrake inokubonelela ngamandla okuqhobosha achanekileyo kwiimeko eziqhelekileyo zokusebenza, ivumela izixhobo ukuba zime kakuhle ngokwenjongo yomqhubi, ziphephe i-inertia ebalekayo; kwiimeko ezingxamisekileyo ezifana nokusilela kombane, ngokulungelelanisa ivalvu yebrake kwicala elingaphambili kunye nokulungelelanisa nezinto ezifana nee-accumulators, inokuphendula ngokukhawuleza kwaye ifezekise ukuqhobosha okungxamisekileyo. Umzekelo, ngexesha lemisebenzi yokwemba, izixhobo ezinkulu ezifana nee-excavators zixhomekeke kwivalvu yebrake ukuba ime ngexesha xa kwenzeka ukusilela ngequbuliso, ukuthintela izixhobo ekutyibilikeni okanye ekulahlekelweni lulawulo, kunye nokuqinisekisa ukhuseleko lwabasebenzi kunye nempahla yezixhobo.
2. Ukuqinisekisa ukusebenza ngokuchanekileyo nangokuzinzileyo
Ukusebenza kwenkqubo ye-hydraulic kufuna ulawulo oluchanekileyo, kwaye iimpawu zevalvu yebrake zichaphazela ngokuthe ngqo ukuchaneka kunye nokuzinza komsebenzi. Ulwakhiwo lwayo oluncinci luvumela ukuba ifakwe kwiindawo ezimxinwa ngaphandle kokuchaphazela uyilo lulonke lwenkqubo ye-hydraulic, kwaye inokubambisana ngokusondeleyo nezinye izinto. Ngaphezu koko, inemvakalelo yonyawo ekhululekileyo, impendulo yoxinzelelo olukhawulezayo, kunye nohlengahlengiso olugudileyo, okuvumela abaqhubi ukuba balawule ngokuchanekileyo amandla okubhuleka ngokweemeko zokusebenza zokwenyani. Thatha i-crane kumatshini wokwakha njengomzekelo. Ngexesha lokusebenza kokuphakamisa, ivalvu yebrake inokumisa ngokuchanekileyo ingalo yokuphakamisa kwindawo echaziweyo, iphephe ukungazinzi ekubhulekeni okunokubangela ukuba into enzima inyikime okanye iwe, iphucule umgangatho wokusebenza kunye nokusebenza kakuhle.
3. Ukuziqhelanisa neemeko zokusebenza ezahlukeneyo kunye neemeko
Iinkqubo ze-hydraulic kwimizi-mveliso eyahlukeneyo zijongene neendawo zokusebenza ezahlukeneyo kunye neemeko. Iiparameter zokusebenza kwevalvu yebhuleki zimisela ukulungelelaniswa kwayo. Le theyibhile ilandelayo ibonisa iiparameter eziphambili zevalvu yebhuleki kunye neemeko zokulungelelaniswa ezifanelekileyo:
| Uhlobo lweParamitha | Iiparameters ezithile | Iimeko zokuZiqhelanisa |
| Ukusebenza okuPhakathi | Ioyile yeHydraulic esekelwe kwiMineral | Igubungela uninzi lweenkqubo ze-hydraulic zoshishino kwaye ihambelana kakuhle. |
| Uluhlu lwe-Viscosity | 2.8 – 380mm²/s | Ingasebenza ngokuzinzileyo kwiimeko ezifana nokubanda ngaphandle kwimimandla esemantla (imfuneko ephantsi ye-viscosity) kunye neendawo zokusebenzela zoshishino ezinobushushu obuphezulu (imfuneko ephezulu ye-viscosity). |
| Uluhlu lobushushu beoyile ye-hydraulic | - 30℃ ukuya kwi-107℃ | Iyakwazi ukumelana neemeko ezahlukeneyo zokusebenza ezinzima ukusuka ekubeninda kakhulu ukuya kubushushu obuphezulu. |
| Uluhlu Lokuseta Uxinzelelo | 20 – 200bar | Iyahlangabezana neemfuno zokubhuleka zemithwalo eyahlukeneyo kunye nobukhulu, ukusuka kwizixhobo zokubhuleka ezincinci ukuya kwizixhobo zokubhuleka ezinamandla zemishini enzima. |
| Uxinzelelo oluphezulu lokufaka lwe-Series yonke | Ibha engama-210 | Ibonelela ngenkxaso eyaneleyo yamandla okubhuleka kwiinkqubo ze-hydraulic ezineemfuno zoxinzelelo oluphezulu. |
4. Ukuphucula ukuthembeka kunye nobomi benkonzo yenkqubo
Ivalvu yebhuleki ineemfuno ezingqongqo zokucoceka (ifikelela kumanqanaba e-18/16/13, ISO4406), kwaye ikwanciphisa uxinzelelo lweoyile olubuyayo oluphezulu lungadluli kwi-1 bar. Oku kunceda ukugcina ucoceko kunye nozinzo lwenkqubo ye-hydraulic. Indawo ecocekileyo yenkqubo inciphisa ukuguguleka kwezixhobo ze-hydraulic ngenxa yokungcola, kwaye uxinzelelo lweoyile olubuyayo oluzinzileyo luthintela ukothuka kwinkqubo okubangelwa kukutshintshatshintsha koxinzelelo, ngaloo ndlela kunciphisa izinga lokusilela kwenkqubo yonke ye-hydraulic, kwandisa ubomi benkonzo yesixhobo, kunciphisa iindleko zokugcinwa kweshishini kunye nexesha lokungasebenzi, kunye nokuqinisekisa ukuqhubeka kwemveliso.
Ivalvu yebhuleki idlala indima ebalulekileyo kwinkqubo ye-hydraulic ngokubhekiselele ekuqinisekiseni ukhuseleko, ulawulo lokusebenza, ukulungelelaniswa kwendalo, kunye nokuthembeka kwenkqubo. Yinto ebalulekileyo ebalulekileyo ekusebenzeni okuzinzileyo, okusebenzayo nokukhuselekileyo kwenkqubo ye-hydraulic. Ngophuhliso oluqhubekayo lwetekhnoloji yemizi-mveliso, iimfuno zokusebenza kwevalvu yebhuleki nazo ziya kuqhubeka zisanda. Ivalvu yebhuleki nayo iya kuhlala ihlaziywa kwaye iphuculwe, inika inkxaso enamandla ngakumbi kuphuhliso lwenkqubo ye-hydraulic.
