I-708-23-00921 I-VALVE YOKUPHUMELA
Intshayelelo kwivalvu yokhuseleko ye-bulldozer1. Inkcazo ye-valve ye-Bulldozer yokukhusela i-valve yokuvula ngokuzenzekelayo kunye nokuvala i-valve yokulawula uxinzelelo efakwe kwiisekethe eziphambili ze-hydraulic systems (ezifana nezixhobo zokusebenza, ukuqondisa, ukuhamba, njl.). Xa uxinzelelo lwenkqubo ludlula ixabiso lokhuseleko olusethiweyo, i-valve ivula ngokuzenzekelayo ukukhulula uxinzelelo; Emva kokuba uxinzelelo lubuyele ngokuqhelekileyo, i-valve ivaliwe ukugcina uxinzelelo oluqhelekileyo lokusebenza kwenkqubo.2. Umgaqo-siseko osebenzayoUmgaqo ongundoqo weevalvu zokhuseleko usekelwe "kwibhalansi yoxinzelelo lwamandla": Ivalve ixhotyiswe nge-spring kunye ne-valve core, kwaye amandla okulayisha kwangaphambili entwasahlobo ahambelana noxinzelelo lokhuseleko (ixabiso elimiselweyo) lenkqubo. Ioyile yehydraulic kumbindi wevalve inkulu kunamandla entwasahlobo, kwaye undoqo wevalve uyatyhilwa uvuleke. Inxalenye yeoli ye-hydraulic ikhutshelwa emva kwitanki yeoli ngokusebenzisa ivalve yokhuseleko (i-pressure relief), ibangela ukuba uxinzelelo lwenkqubo luhle. Xa uxinzelelo oluphakathi ngaphakathi kwesixhobo okanye umbhobho ukhuphuka kwaye udlula umda omiselweyo, i-valve yokhuseleko iya kuvula ngokuzenzekelayo ukunciphisa uxinzelelo ngokukhupha i-medium ngaphandle kwenkqubo, ukuphepha umonakalo wesixhobo okanye iingozi zokhuseleko ezibangelwa ukunyanzeliswa. Ulwakhiwo lwayo luhlala lubandakanya amacandelo aphambili afana nomzimba wevalvu, undoqo wevalvu, kunye nentwasahlobo. Undoqo wevalve ufezekisa ulawulo lokuvula kunye nokuvala phantsi kolungelelwaniso lwamandla entwasahlobo kunye noxinzelelo lwenkqubo, efana ne "spring valve core" umgaqo wokuqhuba weevalvu zokhuseleko lomlayishi.
Ukusetyenziswa kwevalve yokhuseleko lwebulldozer
Inkqubo ye-hydraulic ye-bulldozer "yiziko lamandla" ekusebenzeni kwayo kunye nokuhamba, ukugubungela izixhobo zokusebenza (i-bulldozer, i-bulldozer), inkqubo yokulawula, inkqubo yokuhamba, njl.
1. Isixhobo esisebenzayo se-hydraulic system (imeko yesicelo esingundoqo)
Ibulldozer blade (ukuphakamisa, ukuthambeka) kunye nesixhobo sokukhulula (ukuphakamisa, ukungena emhlabeni) zixhomekeke kwiisilinda ze-hydraulic ukuze ziqhube, kwaye ngexesha lokusebenza, imithwalo yequbuliso (efana ne-bulldozer blade idibana namatye aqinile okanye isixhobo esikhululayo sixinge) sinokubangela ukunyuka kwe-cylindender ngokukhawuleza ngaphakathi.
Ivalve yokhuseleko ifakwe kwisekethe ye-oyile yokungena kwi-cylinder yeoli. Xa uxinzelelo ludlula ixabiso lokhuseleko (ngokuqhelekileyo i-1.1 - i-1.2 amaxesha oxinzelelo olulinganisiweyo lwenkqubo), i-valve ivula ukukhupha i-oyile ephezulu yoxinzelelo kwi-tank yeoli, ukuphepha ukuguqulwa okanye ukugqabhuka kwe-cylinder barrel kunye ne-piston rod ngenxa yokulayisha ngaphezulu, kunye nokukhusela impompo ye-hydraulic eqhuba i-oyile yokukhusela i-oil cylinder.
Inkqubo ye-hydraulic yokulawula
Ukuqhuba iBulldozer kuxhomekeke kwiisilinda zehydraulic (okanye iimotor hydraulic) ukuqhuba isantya esahlukileyo kwiingoma. Ukuba iingoma ziphazamiseka ngequbuliso ngexesha lokuqhuba (njengokuxinga eludakeni okanye ukungqubana nemiqobo), uxinzelelo kwisekethe yeoyile yokulawula luya kwanda ngoko nangoko.
I-valve yokukhusela kwisiphaluka sokulawula inokukhawuleza ukukhulula uxinzelelo, ukukhusela i-cylinder yokulawula, ipompo yokulawula, okanye i-valve yokulawula i-valve ngenxa yokungaphumeleli ngenxa yokunyanzeliswa koxinzelelo, ukuqinisekisa ukuthembeka kwenkqubo yokulawula, kunye nokuphepha umngcipheko "wokunamathela kunye nokulawula"
. Inkqubo yokuhamba nge-hydraulic
Ezinye iibulldozers zisebenzisa i-hydraulic drive yokuhamba (ezifana ne-hydraulic bulldozers ngokupheleleyo), kunye nemoto ehambayo iqhuba umzila ukujikeleza ngeoyile yehydraulic. Ukuba umzila unamathele ngamatye okanye umthwalo ukhulu kakhulu xa ukhuphuka, uxinzelelo kwisiphaluka seoli sokuhamba siya kunyuka ngokungaqhelekanga.
Ivalve yokhuseleko lomjikelo wokuhamba ngoku ivulelwe ukuthomalalisa uxinzelelo, ukukhusela imotor ehambayo, impompo yehydraulic, kunye{0}}noxinzelelo oluphezulu lombhobho ukunqanda ukuqhekeka kwegiya yemoto, ukugqabhuka kwemibhobho, kunye nezinye iziphene ezibangelwa kukugcwala. Ixabiso loShishino Jikelele lweeValuvu zoKhuseleko
Iivalvu zokhuseleko zisetyenziswa ngokubanzi kwimimandla enje ngeebhoyila, iinqanawa zoxinzelelo, iinkqubo zomphunga, njl. njl., umzekelo:
Inkqubo yomphunga: ifakwe ezantsi kweevalvu zokunciphisa uxinzelelo, amatanki ombane, izixhobo zokugcina ubushushu, kunye nezinye izixhobo zokuthintela ukudubula okubangelwa kuxinzelelo olugqithisileyo.
Ishishini elikhethekileyo: I-boiler ye-oyile yokudlulisa ukushisa ithatha i-valve yokukhusela i-A40 ukujongana ne-oyile ephezulu yokushisa kunye negesi ngaphezu kwe-350 degree, kwaye i-compressor yomoya ikhusela ukhuseleko lwetanki yokuqokelela igesi ngokusebenzisa i-valve yokukhusela. Eyona ndlela iphambili "yokuvalwa koxinzelelo loxinzelelo oluzenzekelayo oluzenzekelayo" sisiqinisekiso sendalo yonke sokusebenza ngokukhuselekileyo kweenkqubo zoshishino.
Ivalve yokhuseleko lwe-bulldozer "lukhuseleko lokhuseleko" lwenkqubo ye-hydraulic, ethintela ukugcwala ngokulawula ngokuchanekileyo uxinzelelo. Ukusetyenziswa kwayo kuqhuba kwiinkqubo ezingundoqo ezifana nesixhobo esisebenzayo, ukuqondisa, kunye nokuhamba, kwaye yinxalenye ephambili yokuqinisekisa ukusebenza ngokufanelekileyo nokukhuselekileyo kwee-bulldozers. Ukusetyenziswa okusebenzayo, kuyimfuneko ukujonga rhoqo ukusetwa koxinzelelo kunye nokutywinwa kwevalve yokhuseleko ukuqinisekisa uvakalelo nokuthembeka kwayo.
