Izixhobo ze-Excavator 709-20-51800 umpu ophambili oncedisa ivalve yokunceda umpu

Ukungaphumeleli okubangelwa ivelufa yokhuseleko
Ukugqabhuka kwetyhubhu ye-Hydraulic, i-cylinder lever igobile. Isizathu esona sizathu kukuba i-valve yokukhusela ilungelelaniswe ngokufanelekileyo, kunye nabanye abahlobo bokwemba ukwenzela ukuba kuphuculwe amandla okusebenza ngokubanzi kwe-excavator, ukulungelelanisa ixabiso lokubeka uxinzelelo lwe-valve yokunceda kunye ne-valve yokukhusela ukunyusa amandla e-excavator. Nangona kunjalo, ngokwenza oko, phantsi koxinzelelo oluphezulu lwexesha elide lomsebenzi we-excavator, amathuba okuqhuma kwetyhubhu ye-hydraulic iya kwanda, kwaye i-cylinder lever iya kugoba ngenxa yokuba ayikwazi ukumelana noxinzelelo olukhulu.
Ngenxa yokungaphumeleli kwe-valve yokukhusela, i-spool ibambekile, okanye ioli ivaliwe kwi-port ephuphumayo, eya kubangela uxinzelelo oluphantsi, oluchaphazela ezinye izenzo, amandla anganeleyo, kunye nesenzo esicothayo. Ngeli xesha, abanye abahlobo bokumba baya kulungelelanisa uxinzelelo lwe-valve enkulu yokunceda, kwaye uxinzelelo lohlengahlengiso aluyi kuvuka. Isizathu sokungaphumeleli sinokuthi sibe yingxaki kwi-valve yokukhusela, ngoko i-valve yokhuseleko kufuneka ihlolwe ngokukhawuleza.
Ekubeni ukusebenza kwe-excavator ekusebenzeni okuqhelekileyo akuchaphazeli ngokuthe ngqo kwi-valve yokukhusela, i-valve yokukhusela isoloko ingahoywa kwi-excavator. Kwesi sikhumbuzo, kwinkqubo yokugcinwa kwe-excavator, ivalve yokhuseleko kufuneka ikhumbule kwakhona ukujonga, emva kokuba ivalve yokhuseleko ifunyenwe igugile kunye nezinye iziphene, kufuneka itshintshwe ngevalve entsha yokhuseleko ngexesha.
