Umenzi,Umsebenzi onzima, Umgangatho oPhezulu we-KAMAZ HYDRAULIC LOCK

I-Hydraulic lock (i-valve yokuhlola i-hydraulic control check) isekelwe kwi-valve yokukhangela eqhelekileyo ukongeza icandelo lokulawula i-hydraulic, ukwenzela ukuba i-lock ye-hydraulic ikwazi ukuguqulwa ngesiseko se-valve yokujonga eqhelekileyo ukufezekisa imisebenzi emininzi.

Umgaqo osebenzayo wesitshixo se-hydraulic umi ngolu hlobo lulandelayo:

Xa kungekho ioli ye-hydraulic engena kwi-oyile yokulawula i-oil port, i-lock lock ye-hydraulic ifana ne-valve yokuhlola eqhelekileyo, kwaye ioli inokuhamba ngokukhululekileyo ukusuka kwi-oyile yokungena kwi-oyile, kwaye i-reverse ayikwazi ukudlula konke.Xa i-oyile ye-hydraulic ingena kwi-oyile yokulawula i-oyile kwaye ifikelela kwixabiso layo lokuxinzelela kwangaphambili, i-spool iqhutywe ivuleke phantsi koxinzelelo ukwenza i-valve yokukhangela ivuleke, kwaye i-lock lock iyakwazi ukudlula ngokukhululekileyo kwicala elingasemva.

Isitshixo seHydraulic sahlulwe ngohlobo lwangaphakathi lokuvuza kunye nohlobo lokuvuza lwangaphandle lwesibini.

Uhlobo lwangaphakathi lwe-drain, xa isiphelo esisezantsi sepiston yokulawula i-hydraulic ayilawuli ioyile, ngeli xesha, njengevalve yokujonga ngokubanzi, ioyile yoxinzelelo inokuhamba ngokukhululekileyo kwicala eliya phambili, kwaye ayinakuqukuqela kwicala elingasemva.Nangona kunjalo, xa ioyile yoxinzelelo ingeniswa kwizibuko leoyile yolawulo, isebenza kwisiphelo esisezantsi sepiston yolawulo, kwaye uxinzelelo lolwelo olwenziweyo lwenza ukuba ipiston yolawulo iphakame, idlulisele amandla kwintonga ye-ejector, emva koko inyanzelise enye- indlela ivalve core ukuvula, kwaye i-oyile yesiphaluka engundoqo inokuhamba ngokukhululekileyo kumacala omabini.

Uhlobo lokuvuza, ububanzi be-valve yendlela enye ye-spool inkulu, ukuba uhlobo lokuvuza lwangaphakathi, uxinzelelo lwe-oyile olubuyela umva luphezulu, kuba indawo ebambeleyo ye-valve spool inkulu, ngoko ke i-valve spool phantsi koxinzelelo kwisihlalo sevalve iphezulu, ke uxinzelelo lolawulo olufunekayo ukulawula ipiston ukuvula i-spool yevalve nayo iphezulu, idityaniswa ne-reverse flow outlet pressure esebenza kubuso bepiston yokulawula ukuvelisa amandla asezantsi, Ukucima inxalenye yamandla aphezulu episton yolawulo, ulawulo lweoli lwangaphandle lufuna uxinzelelo oluphezulu, ngaphandle koko i-spool ye-valve yokukhangela kunzima ukuyivula.Ivalve yokuhlola i-Litian yokuvuza yokulawula i-hydraulic yahlula igumbi eliphezulu lepiston yolawulo ukusuka kwisekethe yeoli ephambili kwigumbi, kwaye yongeza izibuko lokuvuza kweoyile elinxibelelana nesekethe yeoli, yehlisa indawo yoxinzelelo kwindawo ephezulu yepiston yolawulo, kwaye kakhulu. kunciphisa amandla okuvula i-valve core.Uhlobo lokuvuza lweLitian lokutshixa lwehydraulic lufanelekile kumathuba apho uxinzelelo lweoyile yehydraulic iphezulu.
