Tšebeliso ea valve ea tšireletso ea bulldozer

Sisteme ea hydraulic ea bulldozer ke "setsi sa matla" bakeng sa ts'ebetso ea sona le ho tsamaea, ho koahela lisebelisoa tse sebetsang (bulldozer, bulldozer), tsamaiso ea tsamaiso, tsamaiso ea ho tsamaea, joalo-joalo Li-valve tsa tšireletso li phetha karolo ea bohlokoa ea tšireletso tsamaisong ena:
1. Sistimi ea hydraulic ea sesebelisoa se sebetsang (boemo ba ts'ebeliso ea mantlha)
Lehare la bulldozer (ho phahamisa, ho thekesela) le sesebelisoa se lokollang (ho phahamisa, ho kena mobung) ho itšetlehile ka li-cylinders tsa hydraulic ho khanna, 'me nakong ea ts'ebetso, meroalo ea tšohanyetso (e kang lehare la bulldozer e kopanang le mafika a thata kapa sesebelisoa se thellang se khomarela) se ka baka keketseho ea tšohanyetso ea khatello ka har'a khatello.
Valve ea ts'ireletso e kentsoe potolohong e kenang ea oli ea cylinder ea oli. Ha khatello e feta boleng ba tšireletso (hangata 1.1 - 1.2 makhetlo a 1.2 khatello e lekantsoeng ea tsamaiso), valve e bula ho ntša oli e nang le khatello e phahameng ho khutlela tanka ea oli, ho qoba ho senyeha kapa ho phatloha ha cylinder barrel le piston rod ka lebaka la ho imeloa, le ho sireletsa pompo ea hydraulic e khannang ho senya pompo ea oli (ho thibela oli).

Sisteme ea hydraulic e tsamaisang
Tsamaiso ea bulldozer e itšetleha ka li-cylinders tsa hydraulic (kapa li-hydraulic motors) ho khanna lebelo la phapang la lipina. Haeba ka tšohanyetso litselana li sitisoa nakong ea ho tsamaisoa (joalo ka ho qaoa ka seretse kapa ho thulana le litšitiso), khatello ea potoloho ea oli e tla eketseha hang-hang.
Sephahla sa tšireletso sepotolohong se tsamaisang se ka imolla khatello ka potlako, se thibela moqomo oa ho tsamaisa, pompo ea ho tsamaisa, kapa valve ea ho laola ho se sebetse ka lebaka la khatello e feteletseng, ho netefatsa ho ts'epahala ha sistimi ea ho tsamaisa, le ho qoba kotsi ea "ho khomarela le ho tsoa taolong"

. Sistimi ea hydraulic e tsamaeang ka maoto
Li-bulldozer tse ling li sebelisa hydraulic drive bakeng sa ho tsamaea (joalo ka li-bulldozer tsa hydraulic ka botlalo), 'me koloi e tsamaeang e khanna pina ho potoloha ka har'a oli ea haeteroliki. Haeba pina e khomaretsoe ke majoe kapa mojaro o moholo haholo ha o hloa, khatello ea potoloho ea oli e tsamaeang e tla eketseha ka tsela e sa tloaelehang.
Belofo ea tšireletso ea potoloho ea ho tsamaea e se e buletsoe ho kokobetsa khatello, ho sireletsa mochini o tsamaeang, pompo ea haeteroliki, le phaephe e phahameng-ho thibela ho phatloha ha lisebelisoa tsa motlakase, ho phatloha ha lipeipi, le liphoso tse ling tse bakoang ke ho tlala. Boleng bo Akaretsang ba Indasteri ba Li-valve tsa Polokeho
Li-valve tsa polokeho li sebelisoa haholo libakeng tse kang li-boilers, likepe tsa khatello, litsamaiso tsa mouoane, joalo-joalo, mohlala:
Sistimi ea mouoane: e kentsoeng tlase ho li-valve tse fokotsang khatello, litanka tsa flash, lisebelisoa tsa polokelo ea mocheso, le lisebelisoa tse ling ho thibela ho phatloha ho bakoang ke khatello e feteletseng.

Indasteri e khethehileng: Mokelikeli oa oli o fetisang mocheso o amohela valve ea tšireletso ea mofuta oa A40 ho sebetsana le mocheso o phahameng oa oli le khase ka holimo ho likhato tse 350, 'me compressor ea moea e sireletsa tšireletso ea tanka ea pokello ea khase ka valve ea tšireletso. Mochini oa mantlha oa "ho koaloa ha khatello ea khatello ea khatello e feteletseng" ke tiisetso ea bokahohle bakeng sa ts'ebetso e bolokehileng ea litsamaiso tsa indasteri.
Valve ea polokeho ea bulldozer ke "mosireletsi" oa sistimi ea hydraulic, e thibelang ho imeloa ka matla ka ho laola khatello ka nepo. Ts'ebeliso ea eona e tsamaisana le lits'ebetso tsa mantlha joalo ka sesebelisoa se sebetsang, ho tsamaisa le ho tsamaea, 'me ke karolo ea bohlokoa ho netefatsa ts'ebetso e ntle le e bolokehileng ea li-bulldozer. Ka ts'ebeliso e sebetsang, hoa hlokahala ho hlahloba khafetsa boemo ba khatello le ho tiisoa ha valve ea tšireletso ho netefatsa hore e na le kutloelo-bohloko le ho tšepahala.
