195-40-00800STEERING VALVE ASSY(B)
Ivalve yokulawula i-B idla ngokuthatha ivalve ye-cycloidal ejikelezayo egcwele uyilo lwehydraulic, equlathe amacandelo aphambili afana nomzimba wevalvu, undoqo wevalvu, umkhono wevalvu, kunye nentwasahlobo yokubuya. Ubume bayo obuphambili bubandakanya: Umzimba weValve kunye ne-oyile ye-oyile: Kukho izibuko zokungena (P), izibuko zokubuya (O), kunye namazibuko e-oyile asebenzayo (A, B) aqhagamshelwe kwisilinda sokuqhuba. I-oyile yangaphakathi ilawula ukuhamba kweoli ye-hydraulic ngokufuduka kwe-valve core.I-valve core kunye ne-valve sleeve: I-valve core iqhutywa yimiqondiso yomatshini okanye yombane ukuba ihambe nge-axially ngaphakathi komkhono wevalve, ukuguqula imeko yokudibanisa i-oyile. Umzekelo, xa undoqo wevalve usiya ngasekunene, i-oyile yesekethe ngu-P → A → igumbi lasekhohlo le-cylinder yamandla, ukufikelela kwisikhokelo sasekhohlo; Ngaphandle koko, jikela ngasekunene.Isiseko se-valve yokulinganisa kunye nomsebenzi wokubamba umthwalo: Ezinye iimodeli (ezifana ne-Crossmfg BA series) zithatha i-valve yokulinganisa i-design core yokunciphisa ukuvuza kunye nokuthintela ukuhla komthwalo, ukuqinisekisa ukuzinza kwee-bulldozers phantsi kwe-slope okanye iimeko ezinzima. Xa ivili lokuqhuba lijikeleza, ukufuduswa kwesiseko sevalve kubangela ukuba ioyile yehydraulic ingene kwisilinda sokuqhuba, ityhale intonga yepiston ukuphambukisa amavili. Ngexesha elifanayo, intwasahlobo yokubuya iqinisekisa ukuba i-valve core ibuyisela ngokuzenzekelayo kwindawo engathathi hlangothi, igcina ukuqhuba ngokuthe ngqo. Isishwankathelo seMvelaphi kunye neSicelo seSicelo seeValve zokuLawula ii-Bulldozers ze-ShantuiKwinkqubo ye-accessory ye-Shantui bulldozer, i-valve yokulawula, njengenxalenye ephambili yenkqubo yokulawula, idlala indima ebalulekileyo kwintsebenzo yokulawula jikelele yomshini. Okwangoku, nangona iiparameters ezithile ze "indibano yevalve yokulawula (B)" ayikhankanywanga ngokuthe ngqo kwiziphumo zokukhangela, uyilo lulonke kunye nolwazi oluhambelanayo lwe-accessory yenkqubo yokulawula ye-Shantui SD i-bulldozers yochungechunge inokudityaniswa ukubonelela ngereferensi yokuqonda ukusetyenziswa kweevalve zokuqhuba ngokweembono zemisebenzi yenkqubo yokulawula, imodeli eqhelekileyo yeempawu zoqwalaselo, njl njl. yamkela imodyuli yoyilo lwesakhiwo, kwaye ivalve yokulawula yeyona nto iphambili yolawulo. Isetyenziswa ngokubanzi kwiimeko ezahlukeneyo zokusebenza kwe-bulldozer ezifana nobunjineli bomhlaba, imigodi, kunye nolwakhiwo lweziseko ezingundoqo, ukuqinisekisa ukulawulwa okuguquguqukayo kunye nokuqhuba okukhuselekileyo kwezixhobo phantsi kweemeko zokusebenza ezinzima.
Iimeko zesicelo kunye neeparamitha zokusebenza
1. Iindawo zesicelo eziqhelekileyo
Ulawulo lokuqhuba i-Bulldozer: Qhuba ngokuthe ngqo isilinda sokuqhuba ukufikelela kwi-engile enkulu yokulawula i-± 30℃okanye ngaphezulu, ilungele iindawo zokwakha ezimxinwa okanye indawo entsonkothileyo.
Isantya esisezantsi esinzima{0}izixhobo zokusebenza ezifana nezilayishi, iitrektara, njalo njalo. Isixhobo sokuqhuba se-BRR sinokumelana nokususwa ukuya kuthi ga kwi-1000m ³/r kunye ne-torque ye-1.6-2.8N · m ngoyilo olululo lwesakhiwo.
I-Emergency manual steering: Ezinye iimodeli (ezifana ne-BZZ2) zixhasa ukusebenza kwe-manual kwimeko yokungaphumeleli kwe-injini, ukugcina umsebenzi osisiseko wokuqhuba ngokudibanisa komatshini.
2. Iimpawu eziphambili zokusebenza
Uxinzelelo kunye nokuhamba: I-BLV-ZXFZ{1}}SY{2}}Iqela le-valve yokulawula i-KTC linoxinzelelo oluphezulu lokusebenza lwe-21MPa kunye nesantya sokuhamba kwe-120L / min, ukuhlangabezana neemfuno zoxinzelelo oluphezulu kunye nokuhamba okukhulu.
Isantya sokuphendula: I-BHR5 yomthwalo we-sensing gear yokulawula, ngokubambisana ne-valve ephambili, inokufezekisa ukuhanjiswa kwenqanaba lokuhamba kwe-millisecond kunye nokuphucula ukuvakalelwa kokulawula.
Ukuthembeka: Ukusetyenziswa kweecores zevalvu ezilungelelanisiweyo kunye nokunxiba-izinto ezixhathisayo (ezifana ne-silicon nitride ceramics) kwandisa ubomi bendibano yevalvu ukuya kwiiyure ezingama-5000.
Iimpawu zobugcisa kunye neendlela zoshishino
Uphuculo olukrelekrele
Ngo-2025, isizukulwana esitsha se-valve yokulawula i-B sidibanisa i-CAN yokulawula ibhasi kunye neenzwa zokufuduka (ezifana ne-Hengli HSQD series), enokubeka iliso kwindawo engundoqo yevalve kunye noxinzelelo lwenkqubo ngexesha langempela, ukufezekisa ukuxilongwa kwempazamo kunye nokubeka iliso kude. Umzekelo, ngetekhnoloji yengxelo evaliweyo yelophu, impazamo yokuchaneka kokuqhuba inokulawulwa ngaphakathi ± 0.5 degree.
Uyilo lokonga amandla
Ukwamkela iteknoloji enovakalelo kumthwalo (njengohlobo lwe-BHR5), ukuhamba kwehydraulic kulungelelaniswa ngokuzenzekelayo ngokomthwalo wokuqhuba, konga i-15% -20% yamandla xa kuthelekiswa namaqela evalvu yemveli. Ezinye iimodeli zikwaxhasa "imowudi yokudada", evumela ukuba ibulldozer ilingane ngokuzenzekelayo nomhlaba kwaye inciphise ukusetyenziswa kwamandla.
Izinto ezintsha zokuQala
Ukusetyenziswa kwee-cores zevalve ye-ceramic (ezifana neeseramikhi ze-alumina) kuphucula ngokubonakalayo ukuxhathisa umhlwa kunye nokumelana nokunxiba, kunye nokwandisa ubomi benkonzo ngokuphindwe ngaphezu kwezihlandlo ezithathu kumhlaba oneasidi okanye kwiindawo ezinothuli oluphezulu. Ngexesha elifanayo, ukusetyenziswa kwezinto zokutywinwa kwe-bio esekelwe kwi-bio kuhambelana nemigangatho ye-EU yendalo, ukunciphisa ukukhutshwa kwekhabhoni nge-10%. Uthotho lweebulldozers ze-PLUS ziye zalungiswa kwinkqubo yolawulo, kunye nolawulo oluguquguqukayo lokulawula isantya esigxininiswe kwisibambo esinye esicwangciswe kwicala lasekhohlo lomqhubi.
uyilo oluhlanganisiweyo lolawulo lubeka iimfuno eziphezulu ekuchanekeni kokulawula kwe-valve yokulawula, efuna ukuba iphendule ngokuchanekileyo kwimisebenzi yokusingatha kunye nokufezekisa izenzo zokulawula ezigudileyo nezisebenzayo. Ukongeza, uthotho lweebulldozer ze-PLUS zisebenzisa iityhubhu ze-snakeskin ezingenamthungo kunye ne-T -izahluli ezinokwakheka kwesixhobo sokubopha isithuthi. Iityhubhu ze-snakeskin ezingenamthungo zinamandla aphezulu kunye nokutywinwa okulungileyo, okunokukhusela ngokufanelekileyo i-harness ye-wiring yesithuthi, kubandakanywa nesiphaluka sokulawula i-valve, ukunciphisa umngcipheko wokulahlekelwa kwevalve yokulawula ngenxa yeempazamo zesekethe, kunye nokuphucula ukuzinza kwenkqubo yokulawula.
