I-hydraulic proportional rotary security valve solenoid 23871482

Njenge-valve yokuphepha ukuvimbela ukugcwala ngokweqile kwesistimu ye-hydraulic i-valve yokusiza isetshenziselwa ukuvimbela ukugcwala kwesistimu, i-valve ivamise ukuvala.Lapho ingcindezi phambi kwe-valve ingeqi umkhawulo osethiwe, i-valve ivaliwe ngaphandle kokuchichima kwamafutha.Lapho ingcindezi ngaphambi kokuba i-valve idlule leli nani elilinganiselwe, i-valve ivula ngokushesha, futhi amafutha ageleza abuyele ethangini noma kumjikelezo ophansi wengcindezi, ngaleyo ndlela avimbele ukugcwala kwesistimu ye-hydraulic.Ngokuvamile i-valve yokuphepha isetshenziswa ohlelweni olunepompo eguquguqukayo, futhi ingcindezi yokulayisha ngokweqile elawulwa yiyo ngokuvamile iphakeme ngo-8% kuya ku-10% ngaphezu kokucindezela kokusebenza kwesistimu.

Njenge-valve echichimayo, ingcindezi ohlelweni lwe-hydraulic igcinwa ingashintshi ohlelweni lwepompo lokulinganisa, futhi isici se-throttle nomthwalo kuhambisana.Ngalesi sikhathi, i-valve ivame ukuvuleka, ngokuvamile i-oyela echichimayo, ngenani elihlukile lamafutha elidingwa indlela yokusebenza, inani lamafutha elichithwe ku-valve likhulu futhi lincane, ukuze kulungiswe futhi kulinganise inani lamafutha angenayo. uhlelo lwe-hydraulic, ukuze ingcindezi ohlelweni lwe-hydraulic ihlale ingashintshi.Nokho, ngenxa yokulahlekelwa amandla engxenyeni echichimayo, ngokuvamile isetshenziswa kuphela ohlelweni olunepompo yokulinganisa amandla aphansi.Ukucindezela okulungisiwe kwe-valve yokusiza kufanele kulingane nokucindezela kokusebenza kwesistimu.

Ukulawula ingcindezi yesilawuli kude: Xhuma indawo yokungena kawoyela yesilawuli sokucindezela esikude endaweni yesilawuli kude (imbobo yokulayisha) yevalvu yokukhulula ukuze ufinyelele ukulawulwa kokucindezela okukude ngaphakathi kwebanga lokucindezela elimisiwe levalvu yokukhulula enkulu.

Njenge-valve yokuthula, imbobo yesilawuli kude (imbobo yokuthula) yevalvu yokukhulula ixhunywe nethangi likaphethiloli ngevalvu ehlehlayo, ukuze ulayini kawoyela ukwazi ukuthululwa.

Ukuze uthole ukulawulwa kwezigaba eziningi zokucindezela okuphezulu nokuphansi, lapho i-valve ehlehlayo ixhuma imbobo yesilawuli esikude (imbobo yokulayisha) ye-valve yokusiza kanye nama-valve okulawula ukucindezela okukude, ukulawulwa kwezigaba eziningi zokucindezela okuphezulu nokuphansi kungenziwa.

Ukuze isetshenziswe njenge-valve yokulandelana, ikhava engaphezulu ye-valve yokukhulula icutshungulwa ibe yimbobo yokukhipha uwoyela, futhi imbobo ye-axial exhunywe ku-valve eyinhloko kanye nekhava ephezulu ivaliwe, njengoba kuboniswe kuMfanekiso e, kanye nembobo yokuchitheka kukawoyela i-valve eyinhloko isetshenziswa njengendawo yokukhipha uwoyela wengcindezi yesibili ezosetshenziswa njenge-valve yokulandelana.

Amavalvu okwehlisa umthwalo ngokuvamile asetshenziswa kumasistimu epompo nawe-accumulator, njengoba kukhonjisiwe kuMfanekiso f.Uma iphampu isebenza ngokujwayelekile, ihlinzeka ngamafutha ku-accumulator.Lapho ukucindezela kwamafutha ku-accumulator kufinyelela ukucindezela okudingekayo, i-valve yokusiza isetshenziswa ngokucindezela kwesistimu ukwenza ipompo ilayishwe, futhi uhlelo luzohlinzeka ngamafutha nge-accumulator futhi lusebenze njengokujwayelekile;Lapho umfutho kawoyela we-accumulator wehla, i-valve yokusiza ivaliwe, futhi iphampu yamafutha iyaqhubeka nokuhlinzeka ngamafutha ku-accumulator, ngaleyo ndlela iqinisekisa ukusebenza okuvamile kwesistimu.
