I-hydraulic balance valve Excavator i-hydraulic cylinder valve core NFED-LHN

Lapho i-valve yokusiza evamile isebenza, ilungiswa ngokuphelele futhi ilawulwa ukucindezela kwentwasahlobo. Ingakwazi ukulungisa ukucindezela kwamafutha we-hydraulic ngokucindezela. Ngokuvamile, uma ingcindezi yamafutha we-hydraulic incane kunokucindezela okudingekayo emsebenzini, i-spool icindezelwa yintwasahlobo ngalesi sikhathi futhi iku-attachment inlet yokugeleza kawoyela we-hydraulic. Kodwa uma ukucindezela kwamafutha we-hydraulic kukhulu kunokucindezela okuvumelekile emsebenzini, ngamanye amazwi, lapho ingcindezi inkulu kunomthombo, i-spool iqhutshwa ngokwemvelo ngamafutha we-hydraulic, futhi uwoyela we-hydraulic uzogeleza ungene futhi gelezela ethangini.

Lapho ingcindezi yamafutha we-hydraulic ikhula kancane kancane, i-spool nayo izobe ivaliwe kancane kancane. . Ngalesi sikhathi, uwoyela we-hydraulic ugeleza nge-valve yokusiza ukuya ethangini elifanele ukugeleza kuzokhuphuka kancane kancane, lapho ingcindezi kawoyela we-hydraulic yehla ukuze ilingane noma ibe ngaphansi komfutho wasentwasahlobo, i-spool izowela ngokwemvelo ukuze ivale i-inlet ehambisanayo. uwoyela we-hydraulic.
Ukukhishwa kukawoyela we-hydraulic yiphampu kawoyela evamile kunenani elinqunyiwe lokucindezela, futhi ingcindezi ehambisanayo yamafutha odonsa amanzi asetshenziswa isilinda esisebenzayo esihambisanayo ngokuvamile incane kakhulu kunokukhishwa kwengcindezi yiphampu kawoyela. Ngalesi sikhathi, sizobona ukuthi lapho ukusebenza sekujwayelekile, kuzoba khona uwoyela we-hydraulic ageleza ethangini ngomshini wevalvu wokusiza. Lokhu kungaqinisekisa ukuthi i-hydraulic cylinder inengcindezi evamile yokusebenza.
