Izesekeli ze-Excavator 709-20-51800 i-valve yokusiza isibhamu esikhulu

Ukwehluleka okubangelwa i-valve yokuphepha
Kuqhume amashubhu e-hydraulic, i-cylinder lever egobile. Isizathu esiyinhloko siwukuthi i-valve yokuphepha ilungiswe ngokwenziwa, futhi abanye abangani abambayo ukuze kuthuthukiswe amandla asebenzayo e-excavator, balungise inani lokusetha ukucindezela kwe-valve enkulu yokusiza kanye ne-valve yokuphepha ukuze kwandiswe amandla omshini wokumba. Kodwa-ke, ngokwenza kanjalo, ngaphansi kokusebenza kwesikhathi eside kwengcindezi ephezulu ye-excavator, amathuba okuqhuma kweshubhu ye-hydraulic azokhuphuka, futhi ngisho ne-cylinder lever izogoba ngoba ayikwazi ukumelana nokucindezela okukhulu.
Ngenxa yokwehluleka kwe-valve yokuphepha, i-spool ibambekile, noma uwoyela uvinjelwe embobeni yokuchichima, okuzoholela ekucindezelweni okuphansi, okuthinta ezinye izenzo, amandla anganele, kanye nesenzo esincane. Ngalesi sikhathi, abanye abangani bokumba bazolungisa ukucindezela kwe-valve enkulu yokusiza, futhi ukucindezela kokulungisa ngeke kuphakame. Isizathu sokuhluleka kungenzeka kube yinkinga nge-valve yokuphepha, ngakho-ke i-valve yokuphepha kufanele ihlolwe ngokushesha.
Njengoba ukusebenza kwe-excavator ekusebenzeni okujwayelekile akuthinteki ngokuqondile nge-valve yokuphepha, i-valve yokuphepha ivame ukunganakwa ku-excavator. Kulesi sikhumbuzo, ohlelweni lokugcinwa kwe-excavator, i-valve yokuphepha kufanele futhi ikhumbule ukuhlola, uma i-valve yokuphepha itholakala ukuthi igugile namanye amaphutha, kufanele ishintshwe i-valve entsha yokuphepha ngesikhathi.
