Ivalvu yokuvala i-bulldozer iyisici esibalulekile ohlelweni lwe-bulldozer hydraulic olusetshenziswa ukulawula ukugeleza koketshezi (imvamisa uwoyela we-hydraulic), ukuvimbela ukuvuza, nokugcina ukuqina kwengcindezi yesistimu. Umsebenzi wayo oyinhloko ukuzuza ukubambisana okunembile phakathi kwe-valve core kanye nesihlalo se-valve ukuvula, ukuvala noma ukulawula izinga lokugeleza kwephaseji kawoyela we-hydraulic, kuyilapho kuncike esakhiweni sokuvala ukuvimbela ukuvuza kwamafutha ezindaweni ezingalindelekile, ukuqinisekisa ukusebenza kahle kwesistimu ye-hydraulic. "ama-valve okuqinisa", umsebenzi wawo oyinhloko ukuvimbela ukuvuza kwamafutha kanye nokungcola kwangaphandle ukuthi kungangeni, ukuqinisekisa ukusebenza okuvamile kwemishini. Okulandelayo yizinhlobo eziyinhloko nezici zezimpawu:V-indandatho yokuvala emise okumise okwenjoloba: indandatho yerabha enwebekayo evalayo enesenzo se-axial, ukuhamba kahle kwezindebe ezivalekayo kanye nokuvumelana nezimo, inganxephezela ukubekezelelana okukhulu nokuchezuka kwama-angular, inganqanda ukuvuza kwamafutha kwangaphakathi noma uwoyela, futhi iphinde ivimbe ukuchaphazeka kwangaphandle noma ukugxambukela kothuli{5}}okusetshenziswe ngokujwayelekile{5}}. izimpawu eziphindaphindayo ezinhlelweni ezisebenza ngohydraulic, ezisetshenziswa kakhulu ekuvaleni amasilinda asebenza ngogesi emishinini yokwakha.O-indandatho: isetshenziselwa kakhulu ukuvala okumile kanye nokuvala okuhambisanayo.Indandatho yokuvala engunxande: ivamise ukufakwa emseleni onesiphambano esingunxande{9}ukuya ngaphandle kwesiqephu esiphakathi nendawo noma esihlinzekweni. function.Y{11}}indandatho yokuvala enomumo: isetshenziswa kakhulu kumishini yokuvala ehambisanayo.Ukungezwani kwentwasahlobo (isitoreji samandla entwasahlobo) indandatho yokuvala: Engeza iziphethu (O-uhlobo,-uhlobo,{15}}u{15}}okumise, njll.) 4 ku-PTFE izinhlobo ze-sealing oil Common, i-oil sealing sealthi evamile. uphawu, njll. Umsebenzi wayo oyinhloko ukuvimbela ukuvuza kwamafutha nokuvimbela uthuli, ukungcola, njll. ukungena ngaphakathi komshini.
Isistimu ye-hydraulic ye-bulldozer inesibopho sokushayela izenzo ezibalulekile njengokuhamba, ukuphakamisa ama-blade, nokukhulula inhlabathi. I-valve yokuvala idlala indima eqondile yokulawula kanye nokuvimbela ukuvuza kuyo. Izinhlelo zokusebenza ezithize zifaka:
Ukulawula ukuphakamisa i-blade
Ukuphakanyiswa nokwehliswa kwama-bulldozer blades kuncike ku-hydraulic cylinder drive, futhi ama-valve okuvala (njengama-valve aqondisayo nama-valve okuhlola) asetshenziselwa ukulawula indlela kanye nokugeleza kukawoyela we-hydraulic ongena kusilinda:
I-valve yokuqondisa ishintsha isiqondiso sokugeleza kwamafutha ngokushintsha indawo ye-valve core, ukufeza ukuphakamisa noma ukwehlisa i-blade yefosholo;
Ivalvu eyodwa-yendlela ivimbela ukugeleza kukawoyela, iqinisekisa ukuthi ifosholo lihlala lisesimweni esizinzile ngesikhathi sokusebenza futhi ligwema ukucwila ngenxa yokuvuza.
Ukulawulwa kwesivinini sohlelo lokuhamba
Ukulawula isivinini se-bulldozer ehamba ngemoto kudinga ukulungisa ukukhishwa kwamafutha we-hydraulic ngokusebenzisa i-valve yokulawula ukugeleza (kuhlanganise nesakhiwo sokuvala). Ivalvu yokuvala ayigcini nje ngokulawula ukugeleza, kodwa futhi ivimbela{1}}ukuvuza kukawoyela ocindezelwe kakhulu ukuze kuqinisekiswe ukudluliswa okuzinzile kwamandla okuhamba nokugwema ukushintshashintsha kwesivinini.
Ukulawulwa kokusebenza kokukhulula inhlabathi
Ukufakwa nokuphakamisa izenzo zomshini wokukhulula inhlabathi nazo ziqhutshwa uhlelo lwe-hydraulic, futhi i-valve yokuvala (njenge-valve yokuchichima) ingasetha ukucindezela okukhulu kwesistimu. Lapho umshini wokukhulula inhlabathi uhlangabezana nokugcwala okuqinile kwenhlabathi, ivalvu yokuchichima iyavuleka ukuze ikhulule ingcindezi, kuyilapho incike esakhiweni sokuvala ukuze kuvinjwe ukuvuza kukawoyela esimweni sokungakhululeki futhi kuvikelwe izingxenye ze-hydraulic.
Ukugcinwa kwengcindezi yesistimu
Isistimu ye-hydraulic ye-bulldozer idinga ukugcina ingcindezi ethile yokusebenza. I-valve yokuvala (njenge-valve yokulawula ukucindezela) ibambelela ngokuqinile kumongo we-valve kanye nesihlalo ukuvimbela ukuvuza kukawoyela lapho kungekho senzo, iqinisekisa ukucindezela kwesistimu okuzinzile kanye nokunciphisa ukulahlekelwa kwamandla.
3, Ukubaluleka Kwamavalvu Avaliwe
Ukuvimbela ukuvuza: Ukuvuza kukawoyela weHydraulic kungabangela ukwehla kwengcindezi yesistimu, ukusebenza kahle, ngisho nokwehluleka kwemishini (njengokusebenza kancane namandla anganele). Ukubekwa uphawu okuthembekile kwe-valve yokuvala kungagwema izinkinga ezinjalo futhi kwandise impilo yesevisi yamafutha we-hydraulic.
Ukulawula okunembile: Ngesenzo esinembile se-valve core, i-valve yokuvala ingakwazi ukufeza ukulungiswa okunembile kwezinga lokugeleza, ingcindezi, kanye nesiqondiso, iqinisekisa ukushelela nokulawulwa kokusebenza kwe-bulldozer (njengokulungiswa okuhle kwe-blade yefosholo nokuhluka okufanayo kwejubane lokuhamba).
Isistimu yokuvikela: Ngaphansi kokugcwala ngokweqile, ukushintshashintsha kwengcindezi nezinye izimo zokusebenza, ama-valve okuvala (njengama-valve okuphepha) angasabela ngokushesha futhi anqamule noma akhulule ukucindezela, kuhlanganiswe nezakhiwo zokuvala ukuvimbela ukuvuza okungavamile nokuvikela izingxenye eziyinhloko zama-hydraulic njengamaphampu kawoyela namasilinda ekulimaleni.
Kafushane, i-valve yokuvala i-bulldozer "ihabhu lokulawula" lesistimu ye-hydraulic, futhi ukuvala nokuthembeka kwayo kuthinta ngokuqondile ukusebenza kahle kokusebenza, ukuphepha, kanye nempilo yesevisi ye-bulldozer. Kuyingxenye ebalulekile yokuqinisekisa ukusebenza okuzinzile kwegandaganda ezimeni zokusebenza eziyinkimbinkimbi njengezimayini nezindawo zengqalasizinda.
