I-Hydraulic elinganayo yokhuseleko ivelufa ye-solenoid ye-23871482

Njengevalve yokukhusela ukukhusela ukugqithiswa kwenkqubo ye-hydraulic i-valve yokunceda isetyenziselwa ukuthintela ukugqithiswa kwenkqubo, i-valve ivalwe ngokuqhelekileyo. Xa uxinzelelo oluphambi kwevalve aludluli umda omiselweyo, i-valve ivaliwe ngaphandle kokuphuphuma kweoli. Xa uxinzelelo ngaphambi kokuba i-valve idlule le xabiso lomda, i-valve ivula ngokukhawuleza, kwaye ioli ibuyele kwi-tank okanye i-circuit ye-low pressure circuit, ngaloo ndlela ikhusela ukugqithiswa kwenkqubo ye-hydraulic. Ngokuqhelekileyo i-valve yokukhusela isetyenziswe kwinkqubo kunye nepompo eguquguqukayo, kwaye uxinzelelo olugqithisiweyo olulawulwa yiyo ngokubanzi luyi-8% ukuya kwi-10% ephezulu kunoxinzelelo olusebenzayo lwenkqubo.

Njenge-valve yokuphuphuma, uxinzelelo kwi-hydraulic system lugcinwa rhoqo kwi-quantitative pump system, kunye ne-throttle element kunye nomthwalo uhambelana. Ngeli xesha, i-valve ivame ukuvuleka, idla ngokugqithisa ioli, kunye nenani elahlukileyo leoli elifunwa ngumatshini wokusebenza, inani leoli elichithwe kwi-valve likhulu kwaye lincinci, ukwenzela ukuba ulungelelanise kwaye ulungelelanise inani leoli engena. inkqubo ye-hydraulic, ukwenzela ukuba uxinzelelo kwi-hydraulic system luhlale luhleli. Nangona kunjalo, ngenxa yokulahlekelwa kwamandla kwinxalenye yokuphuphuma, ngokuqhelekileyo isetyenziswa kuphela kwinkqubo kunye nepompo yobungakanani obuphantsi kwamandla. Uxinzelelo olulungisiweyo lwevalve yokunceda kufuneka lulingane noxinzelelo olusebenzayo lwenkqubo.

Ukulawulwa koxinzelelo olude: Xhuma i-oyile yokungena kwi-remote pressure regulator kwi-remote control port (i-port yokukhulula) ye-valve yokukhulula ukuphumeza ukulawulwa koxinzelelo olukude ngaphakathi koluhlu loxinzelelo olusetiweyo lwevalve enkulu yokunceda.

Njenge-valve yokukhulula, i-port yokulawula i-remote (i-port yokukhulula) ye-valve yokunceda idibaniswe ne-tank ye-fuel nge-valve yokubuyisela umva, ukwenzela ukuba umgca weoli unokukhutshwa.

Ukulawula izigaba ezininzi zoxinzelelo oluphezulu kunye noluphantsi, xa i-valve yokubuyisela idibanisa i-port ekude (i-port yokukhulula) ye-valve yokukhulula kunye ne-valve yokulawula uxinzelelo olukude, ulawulo lwezigaba ezininzi zoxinzelelo oluphezulu kunye noluphantsi lunokuphunyezwa.

Ukusetyenziswa njengevalve yolandelelwano, isigqubuthelo esingaphezulu sevalve yoncedo sicutshungulwa kwi-oyile drain port, kwaye umngxuma we-axial uqhagamshelwe kwivalve ephambili kunye nesigqubuthelo esingaphezulu sivaliwe, njengoko kubonisiwe kuMfanekiso e, kunye ne-oyile yokuchitheka kwezibuko. ivalve ephambili isetyenziswa njenge oyile yoxinzelelo lwesibini ekufuneka isetyenziswe njengevalve yolandelelwano.

Iivalvu zokukhulula zisetyenziswa ngokubanzi kwiinkqubo zempompo kunye ne-accumulator, njengoko kubonisiwe kuMfanekiso f. Xa impompo isebenza ngokuqhelekileyo, inika ioli kwi-accumulator. Xa uxinzelelo lweoli kwi-accumulator lufikelela kuxinzelelo olufunekayo, i-valve yokunceda iqhutywe ngoxinzelelo lwenkqubo yokwenza ipompo ikhuphe, kwaye inkqubo iya kunika ioli nge-accumulator kwaye isebenze njengesiqhelo; Xa uxinzelelo lweoli lwe-accumulator luhla, i-valve yokunceda ivaliwe, kwaye ipompo yeoli iyaqhubeka nokubonelela ngeoli kwi-accumulator, ngaloo ndlela iqinisekisa ukusebenza okuqhelekileyo kwenkqubo.
