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 yokufaka uwoyela yesilawuli sokucindezela esikude endaweni yesilawuli kude (imbobo yokulayisha) yevalvu yokukhulula ukuze ufinyelele ukulawulwa kwengcindezi ekude 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 kude (imbobo yokuthula) ye-valve yokusiza kanye nama-valve amaningana 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 yokuphuma kawoyela yengcindezi 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.
