I-valve yokutywinwa kwe-bulldozer yinto ephambili kwi-bulldozer hydraulic system esetyenziselwa ukulawula ukuhamba kwamanzi (ngokuqhelekileyo ioli ye-hydraulic), ukukhusela ukuvuza, kunye nokugcina ukuzinza koxinzelelo lwenkqubo. Umsebenzi wayo ongundoqo kukuphumeza intsebenziswano echanekileyo phakathi kwesiseko se-valve kunye nesihlalo se-valve ukuvula, ukuvala okanye ukulawula izinga lokuhamba kwe-oyile ye-hydraulic, ngelixa uthembele kwisakhiwo sokutywinwa ukuthintela ukuvuza kweoli kwiindawo ezingalindelekanga, ukuqinisekisa ukusebenza kakuhle kwenkqubo ye-hydraulic. "Iivalve zokutywina", umsebenzi wayo ophambili kukuthintela ukuvuza kweoli kunye nokungcola kwangaphandle ekungeneni, ukuqinisekisa ukusebenza okuqhelekileyo kwezixhobo. Ezi zilandelayo ziintlobo eziphambili kunye neempawu zamatywina: V -umsesane wokutywina omile: umsesane wokutywina werabha elastic kunye nesenzo se-axial, ukuhamba kakuhle komlomo wokutywina kunye nokuguquguquka, kunokuhlawula ukunyamezela okukhulu kunye nokuphambuka kwe-angular, kunokuthintela igrisi yangaphakathi okanye ukuvuza kwe-oyile, kwaye iphinde ithintele ukutshiza kwangaphandle okanye uthuli olusetyenziswayo kwi-uthuli oluqhelekileyo{5}} amatywina abuyelanayo kwiinkqubo zamanzi, ezisetyenziswa ngokubanzi ekutywineni iisilinda zamanzi kumatshini wokwakha.O{7}}ringi: isetyenziselwa ukutywina okumileyo kunye nokutywinwa okubuyelanayo.Iringi yokutywina yoxande: ifakelwe ngokubanzi kwigroove ngomnqamlezo oxande{9}ukuya kwisangqa okanye icandelo lokutywina kwisangqa function.Y-imisesane yokutywina emile: isetyenziswa ngokubanzi kwizixhobo zokutywina ezihambelanayo. Uxinzelelo lwasentwasahlobo (ugcino lwamandla entwasahlobo) umsesane wokutywina: Yongeza imithombo (O-uhlobo, udidi lweV{14}}, U{15}}imilo, njl.njl.) 4 ukuya kwi-PTFE ukutywinwa kweoli, iintlobo ze-oyile yokutywina i-oyile eqhelekileyo. uphawu, njl. Umsebenzi walo oyintloko kukuthintela ukuvuza kweoli kunye nokuthintela uthuli, ukungcola, njl.
Inkqubo ye-hydraulic ye-bulldozer inoxanduva lokuqhuba izenzo eziphambili ezifana nokuhamba, ukuphakamisa i-blade, kunye nokukhulula umhlaba. Ivalve yokutywina idlala indima echanekileyo yokulawula kunye nokuthintela ukuvuza kuyo. Usetyenziso oluthile lubandakanya:
Ulawulo lokuphakamisa i-blade
Ukunyuswa kunye nokwehliswa kweebludo ze-bulldozer kuxhomekeke kwi-hydraulic cylinder drive, kunye neevalvu zokutywina (ezifana neevalvu ezikhomba indlela kunye neevalvu zokujonga) zisetyenziselwa ukulawula indlela kunye nokuhamba kweoyile ye-hydraulic engena kwi-cylinder:
I-valve yokuqondisa itshintsha i-oil flow flow direction ngokutshintsha i-valve core position, ukufezekisa ukuphakamisa okanye ukuthoba i-blade yefosholo;
Enye-ivalve yendlela inqanda ukuphuma kwe-oyile ngasemva, iqinisekisa ukuba umhlakulo uhlala ukwindawo ezinzileyo ngexesha lokusebenza kwaye unqanda ukutshona ngenxa yokuvuza.
Ukulawulwa kwesantya senkqubo yokuhamba
Ukulawulwa kwesantya se-bulldozer ehamba ngemoto kufuna ukulungelelanisa ukukhutshwa kweoli ye-hydraulic ngokusebenzisa i-valve yokulawula ukuhamba (kubandakanywa nesakhiwo sokutywinwa). Ivalve yokutywina ayilawuli kuphela ukuhamba, kodwa ikwanqanda{1}uxinzelelo oluphezulu lokuvuza kwe-oyile ukuqinisekisa ukuhanjiswa okuzinzileyo kwamandla okuhamba kunye nokunqanda ukuguquguquka kwesantya.
Ukulawulwa komsebenzi wokukhulula umhlaba
Ukufakwa kunye nokuphakamisa izenzo zesixhobo sokukhulula umhlaba nazo ziqhutywa yi-hydraulic system, kunye nevalve yokutywina (efana nevalve yokuphuphuma) inokumisela uxinzelelo oluphezulu lwenkqubo. Xa isixhobo sokukhulula sidibana nokugcwala komhlaba oqinileyo, ivelufa yokuphuphuma kwayo iyavuleka ukuthomalalisa uxinzelelo, ngeli lixa sixhomekeke kwisakhiwo sokutywina ukunqanda ukuvuza kwe-oyile kwimeko yokungaphumli kunye nokukhusela amalungu oxinzelelo lwehydraulic.
Ukugcinwa koxinzelelo lwenkqubo
Inkqubo ye-hydraulic ye-bulldozer idinga ukugcina uxinzelelo oluthile lokusebenza. Ivalve yokutywina (njengevalve yokulawula uxinzelelo) ibambelela ngokuqinileyo kumbindi wevalve kunye nesihlalo ukuthintela ukuvuza kwe-oyile xa kungekho ntshukumo, iqinisekisa uxinzelelo oluzinzileyo lwenkqubo kunye nokunciphisa ukulahleka kwamandla.
3, Ukubaluleka kweeVave ezitywiniweyo
Ukuthintela ukuvuza: Ukuvuza kweoyile yeHydraulic kunokubangela ukuncipha koxinzelelo lwenkqubo, ukusebenza kakuhle, kunye nokusilela kwesixhobo (njengokusebenza kancinci kunye nokungonelanga kwamandla). Ukutywinwa okuthembekileyo kwevalve yokutywina kunokuphepha iingxaki ezinjalo kunye nokwandisa ubomi benkonzo yeoli ye-hydraulic.
Ulawulo oluchanekileyo: Ngokusebenzisa isenzo esichanekileyo se-valve core, i-valve yokutywina inokufezekisa ukulungelelaniswa okuchanekileyo kwesantya sokuhamba, uxinzelelo, kunye nolwalathiso, ukuqinisekisa ukuguquguquka kunye nokulawulwa komsebenzi we-bulldozer (njengokulungiswa kakuhle kwe-blade yefosholo kunye nokuhluka okufanayo kwesantya sokuhamba).
Inkqubo yokukhusela: Ngaphantsi komthwalo ogqithisiweyo, ukuguquguquka koxinzelelo kunye nezinye iimeko zokusebenza, iivalve zokutywina (ezifana nezivalo zokhuseleko) zinokuphendula ngokukhawuleza kwaye zinqumle okanye zinciphise uxinzelelo, zidibene nezakhiwo zokutywina ukukhusela ukuvuza okungaqhelekanga kunye nokukhusela i-core hydraulic components ezifana neepompo zeoli kunye neesilinda kumonakalo.
Isishwankathelo, i-valve yokutywina i-bulldozer "yi-hub yokulawula" ye-hydraulic system, kwaye ukutywinwa kwayo kunye nokuthembeka kuchaphazela ngokuthe ngqo ukusebenza kakuhle, ukhuseleko kunye nobomi benkonzo ye-bulldozer. Licandelo eliphambili lokuqinisekisa ukusebenza okuzinzileyo kwebulldozer kwiimeko zokusebenza ezinzima ezifana nemigodi kunye neziza zeziseko zophuhliso.
