Ki sa ki valv fren men?

1.Ki sa ki valv fren men
Valv kontwòl men an se aparèy kle nan pakin, fren pakin ak fren echapman nan pwosesis fren sèvis machin.
Fren pakin nan veyikil la konplètman lage epi veyikil la nan eta kouri;Lè manch lan se nan pozisyon an bloke, tren an se nan eta frenaj konplè;Lè manch lan se nan pozisyon chèk la, fren pakin nan traktè a se nan eta a frenaj, men trelè a se nan eta a frenaj konplètman lage.
Lè manch lan deplase, kam manch lan pouse gwo piston an desann, peze sezon prentan an balans, pouse piston an anba, fèmen tiyo echapman an, konplètman louvri valv la inlet nan valv adisyonèl la, ak lè a konprese nan kavite a antre nan kavite a. , ak Lè sa a, divize an de fason.Yon fason antre nan chanm fren an prentan nan bouch la lage fren an pakin nan traktè a;Antre valv fren trelè a nan pò a pou libere fren pakin trelè a.Lè manch lan nan ranje a, fren pakin nan machin nan konplètman lage.
2.Fonksyon valv kontwòl manyèl
Frenaj motè se frenaj echapman.Pou machin lou, frenaj sitou gen ladan sèvis frenaj;Espas pou, fren pakin, fren echapman.Fren sèvis la reyalize atravè tiyo mèt fren an doub-chanm, fren pakin ak fren pakin reyalize atravè tiyo kontwòl manyèl la, epi fren echapman reyalize nan tiyo papiyon fren echapman an.Se tiyo echapman fren papiyon enstale dèyè kawotchou tiyo echapman motè a.Lè yo opere valv bouton pouse a, presyon lè a pase nan silenn k ap travay nan tiyo echapman fren papiyon pou fè piston lè a nan silenn k ap travay la aji, konsa kondwi baton pouse a vire disk valv papiyon 90 degre, fèmen tiyo echapman an. kawotchou, fè tiyo echapman motè a bloke.Lè tiyo echapman motè a bloke, piston an nan silenn motè a pa ka vwayaje nòmalman, epi li dwe reziste rezistans sa a, Nan fason sa a, anba efè rezistans lè a, aksyon piston motè a ap redwi.Akòz fòs traction, vitès machin lan ap ralanti.
3.Fòt komen nan valv kontwòl oto manyèl
3-1 Lè manch lan deplase, gwo piston, prentan balans ak piston balans deplase anlè, tiyo echapman an louvri epi valv inlet la fèmen;Se valv la inlet nan valv adisyonèl la fèmen.Presyon lè pwodiksyon P, I "22 diminye lineyè a zewo pandan ang manch lan ap ogmante.
3-2 Lè manch lan soti nan 730 a 820, valv inlet lè 6 nan valv adisyonèl la louvri, epi efè frenaj trelè a lage.
3-3Tcheke si machin nan ka pake sou ranp lan sèlman anba fren pakin nan traktè a.Lè manch lan lage, manch lan otomatikman retounen nan pozisyon bloke fren pakin lan.
3-4 Pati ki domaje yo ka enspekte ak ranplase nan kò ki pi ba a ak nan mitan kò a.
3-4 Si gen divès kalite andedan valv kontwòl manyèl la, O-bag la domaje, piston an chire, kavite enteryè a oswa kèk pati bloke oswa bloke, efè frenaj nòmal la pa ka pwodwi.
3-5 Depanaj:
1.(1) Retire boulon yo nan kouvèti ki pi ba nan tiyo kontwòl manyèl la, retire piston an nan chanm enteryè a, tcheke, netwaye epi fè yon asanble rezonab.
2.(2) Limit itilizasyon deziyen valv kontwòl manyèl la se apeprè 50000 km.Li ta dwe demonte pou "enspeksyon konplè" epi ekipe ak yon twous reparasyon espesyal pou bay kondisyon pratik pou antretyen.
4. Fonksyon valv kontwòl manyèl
Se valv la kontwòl manyèl ki konekte ak bouton an chanjman nan taksi a.Se mouvman an nan valv la bobin nan kò a valv kontwole manyèlman kontwole konvèsyon an nan lwil idwolik.Se presyon lwil oliv prensipal la apwovizyone nan valv la kontwòl manyèl, epi se lwil oliv la presyon nan sikwi lwil oliv prensipal la apwovizyone nan sikwi lwil oliv ki koresponn lan anba diferan kondisyon travay atravè mouvman an nan valv la glise.
5. manyèl koòdone valv
Pati kontwòl valv la leve pou retire pousyè sak konpoze de silenn lè, valv ranvèse elektwomayetik, plak valv ak baton leve.
Lè limit switch la obligatwa, switch deteksyon an ka ajoute, epi switch mayetik sou silenn lan kapab tou itilize pou deteksyon limit.Valv kontoune jeneral la gen deteksyon vwayaj.
Sou kontwòl elektrik la, yo itilize yon sèl liy aksyon kontwòl pou kontwole valv ranvèse solenoid la.Se kantite liy yo detèmine dapre tiyo ranvèse chwazi a.
zafè ki bezwen atansyon:
Nan kèk kote, akòz limit tanperati a, valv la poppet ka chwazi tou valv elektrik olye pou yo silenn lè.Pifò tiyo poppet yo kontwole pa silenn lè.
Nou gen nimewo valv jan sa a:
