I-Hydraulic solenoid valve 4212228 TOSD-06-151 izingxenye zemishini yokwakha

I-electro-hydraulic proportional valve ibizwa ngokuthi i-proportional valve. Amavalvu avamile we-hydraulic angakwazi kuphela ukulawula ukucindezela nokugeleza kokugeleza koketshezi ngokusetha kusengaphambili. Kodwa-ke, lapho umshini wemishini udinga ukulungiswa noma ukulawulwa okuqhubekayo kokucindezela nokugeleza kwemingcele yesistimu ye-hydraulic ngesikhathi senqubo yokusebenza, isibonelo. Ithebula lomsebenzi liyadingeka ukuze kuzuzwe okuphakelayo ngesivinini soshintsho oluhamba kancane, olusheshayo nolunensayo phakathi kokuphakelayo komsebenzi, noma ukulingisa ijika elilungile lokulawula ngokunemba okuthile ukuze kuzuzwe ukulawula amandla. Ama-valve e-hydraulic ajwayelekile awakwazi ukufeza. Ngalesi sikhathi, i-hydraulic system ingalawulwa yi-valve ye-electro-hydraulic proportional valve.

I-electro-hydraulic proportional valve iwuhlobo lwevalvu elawula ngokuqhubekayo nangokulinganayo isiqondiso sokugeleza, izinga lokugeleza kanye nokucindezela kwesistimu ye-hydraulic ngokusho kwesignali kagesi yokufaka. Iqukethe izingxenye ezimbili: idivayisi yokuguqula ngokulinganayo kagesi-mechanical kanye ne-hydraulic control valve body. Owokuqala uguqula isignali kagesi yokufaka ibe amandla omshini kanye nokuphumayo kokugudluza ngokuqhubekayo nangokulingana, kuyilapho ugesi ukhipha ingcindezi futhi ugeleze ngokuqhubekayo nangokulinganayo ngemva kokwamukela amandla anjalo omshini nokugudluza.
Ukwakhiwa kwevalvu ye-electro-hydraulic proportional valve ikakhulukazi kunezindlela ezimbili: eyodwa iwukushintsha idivayisi yokulungisa eyenziwa ngesandla yevalvu ye-hydraulic yendabuko ngozibuthe olinganayo noma ukufaka esikhundleni sikazibuthe ojwayelekile. Eyesibili ithuthukiswa i-electro-hydraulic servo valve ukuze kube lula ukwakheka nokunciphisa ukunemba. Ama-valve alinganisayo achazwe ngezansi wonke abhekisela kowangaphambili, okuyiwona ojwayelekile wamavalvu alinganayo anamuhla. Iyakwazi ukushintshaniswa nama-valve avamile we-hydraulic.
