I-hydraulic solenoid valve 4212228 TOSD-06-151 iindawo zoomatshini bokwakha

Ivalve ye-electro-hydraulic proportional valve ibizwa ngokuba ivelufa elinganayo. Iivalvu zehydraulic eziqhelekileyo zinokulawula kuphela uxinzelelo kunye nokuhamba kolwelo ngokuseta kwangaphambili. Nangona kunjalo, xa isixhobo sesixhobo sifuna ukulungiswa okanye ukulawulwa okuqhubekayo koxinzelelo kunye neeparitha zokuhamba kwenkqubo ye-hydraulic ngexesha lenkqubo yokusebenza, umzekelo. Itheyibhile yomsebenzi iyadingeka ukufezekisa ukutya ngesantya sokutshintsha okucothayo, okukhawulezayo kunye nokucothayo okuqhubekayo ngexesha lokutya komsebenzi, okanye ukulinganisa i-curve yolawulo olufanelekileyo ngokuchaneka okuthile ukufezekisa ulawulo lwamandla. Iivalvu eziqhelekileyo ze-hydraulic azikwazi ukufikelela. Ngeli xesha, inkqubo ye-hydraulic inokulawulwa yi-valve ye-electro-hydraulic proportional valve.

Ivalve ye-electro-hydraulic proportional valve luhlobo lwevalvu elawula ngokuqhubekayo nangokulinganayo indlela yokuhamba, isantya sokuhamba kunye noxinzelelo lwenkqubo ye-hydraulic ngokuhambelana nomqondiso wegalelo lombane. Iqulathe ngamacandelo amabini: isixhobo sokuguqula umbane-omatshini ngokulinganayo kunye nomzimba wevalve yolawulo loxinzelelo lolwelo. Eyangaphambili iguqula igalelo lombane libe ngamandla omatshini kunye nemveliso yokufuduswa ngokuqhubekayo nangokulinganayo, ngelixa isiphumo sokugqibela sikhupha uxinzelelo kunye nokuhamba ngokuqhubekayo nangokulinganayo emva kokwamkela amandla omatshini kunye nokufuduswa.
Ukuphuhliswa kwevalvu yokulinganisa ye-electro-hydraulic proportional ikakhulu kuneendlela ezimbini: enye kukubuyisela isixhobo sohlengahlengiso semanyuwali sevalve ye-hydraulic yesiqhelo kunye ne-electromagnetic valve okanye ukubuyisela umazibuthe wesiqhelo. Eyesibini iphuhliswa yi-valve ye-servo ye-electro-hydraulic ukwenza lula isakhiwo kunye nokunciphisa ukuchaneka. Iivalvu ezilungelelanisiweyo ezichazwe ngezantsi zonke zibhekisa kweyangaphambili, eyona ndlela iphambili yeevalvu ezilungelelanisiweyo zanamhlanje. Iyakwazi ukutshintshwa kunye neevalvu eziqhelekileyo ze-hydraulic.
