Ku-Komatsu PC200-8 Ivalvu yokukhulula i-Boom Main valve yokusiza isibhamu

Lokhu esikhuluma ngakho kuvalvu yokusiza enkulu yilapho umfutho wesistimu ukhuphuka kancane, imodeli yesithupha
Lapho umehluko wengcindezi phakathi kweziphetho ezimbili ze-valve eyinhloko ye-plunger udlula umsebenzi we-splunger ethambile ye-valve eyinhloko, i-valve enkulu ye-plunger iyaphakanyiswa, i-valve eyinhloko ivuliwe, isiphethu sixhunywe ethangini likawoyela, inani elikhulu. kawoyela iphonswa ngembobo ye-valve enkulu, bese igeleza ibuyele ethangini likawoyela ngembobo yokubuya kawoyela, okuyinqubo yokulawula ukuchichima kwengcindezi.Ukuqonda lesi simiso kungaqonda isimiso sokusebenza se-boom ukugcina i-valve iphansi ngokufanisa.
Uma ingalo ye-hydraulic excavator yehliswa, kubalulekile ukuqaphela ukuthi incike ku-valve ye-PPC elawulwa kusukela ekuguquleni.
Uwoyela wengcindezi eqondisayo kuqala uphusha i-valve yesilayidi elawula i-valve eyinhloko (i-valve ilingana ne-valve yokushayela kuvalvu yokusiza umshayeli, ehamba ngalesi sikhathi.
Amafutha asegunjini elingaphansi kwengalo abuyela ethangini ngembobo kawoyela yangaphakathi yevalvu eyinhloko ngendlela evulwe ivalve yesilayidi.Lapho ukugeleza kwamafutha okucindezela kudlula emgodini wokudambisa we-valve eyinhloko ye-valve yokubamba, ukwehla kwengcindezi kukhiqizwa, ukuze ukucindezela kwamafutha okusebenza emaphethelweni aphezulu nangaphansi kwe-valve eyinhloko kungalingani, okwenza umehluko othile wokucindezela.I-valve eyinhloko ivuliwe, futhi uwoyela ocindezelayo ogeleza usuka phansi we-boom ugeleza nge-valve eyinhloko ukuya ku-valve yokulawula i-boom.Uma kunomfutho ophakeme ongavamile endaweni engaphansi yesilinda se-boom, i-valve yokuphepha ku-valve yokubamba iyavuleka ukuze idlale indima yokuvikela.
