Ifanele izesekeli ze-excavator loader hydraulic proportional valve RE177539

Ungase ungazi okuningi mayelana nama-valve okuphepha, kodwa uma kuziwa ekugcwaliseni (okuchichimayo) ama-valve, ama-valve embobo kawoyela noma izibhamu zesibili, ungase ube nombono. Ezinye izinkinga ezivamile zokumba zibangelwa ukwehluleka kwama-valve okuphepha, njengejubane elincane, ubuthakathaka, ukuqhuma kwepayipi noma ukuqhuma kwepayipi le-hydraulic, ukugoba kwe-cylinder lever nokunye. Ngaphandle kokuningi ongakusho, umzalwane olandelayo wokumba uzokunikeza isingeniso esiningiliziwe sesixazululo se-valve yokuphepha kanye nokwehluleka kwayo, ngikholelwa ukuthi uzobe ugcwele isivuno.
I-valve yokukhulula ifakwe ku-valve yokulawula eyinhloko (umsabalalisi) ohlangothini lwesiqu sokusebenza. Ngokubukeka, i-valve yokukhulula iyisilinda futhi ifana kakhulu ne-valve enkulu yokukhulula. Umehluko yintambo yokulungisa phezulu. Ivalvu yokuphepha inomucu owodwa kanti ivalve enkulu yokusiza inemicu emibili. Endaweni yokusetha ingcindezi, indawo yokucindezela ye-valve yokuphepha iphakeme kune-setpoint yokucindezela ye-valve enkulu yokusiza.
Ngaphansi kwezimo ezijwayelekile, i-valve yokuphepha ayihlanganyeli emsebenzini, ngakho-ke isilinganiso sokucindezela kwe-valve yokuphepha sikhethekile futhi asikwazi ukulinganiswa ngokuqondile nethuluzi. Ukucindezela kwe-valve yokusiza eyinhloko kudinga ukukhushulwa kusengaphambili futhi kungalinganiswa kuphela ngemva kokuba kuphakeme kunevelu yokucindezela ye-valve yokuphepha.
