1. Lungiselela uyilo lweKhoyili ye-Electromagnetic

Ikhoyili ye-solenoid ivelisa amandla emagnethi okuqhuba ivalvu. Uphuculo oluphambili luquka:

• Ukunyuka kweeKhoyiliUkongeza ii-wire windings ezingaphezulu kwandisa i-magnetic flux, kunciphisa ukulibaziseka kokusebenza14.

• Izixhobo ezinganyangekiyo kakhulu: Ukusebenzisa ucingo lobhedu olucocekileyo kakhulu kunciphisa ukulahleka kwamandla kunye nokuveliswa kobushushu, kuqinisekisa ukusebenza okuzinzileyo3.

• Uqwalaselo lwe-Dual-Coil: Uphononongo olwenziwe nguJiang et al. lufumene ixesha lokuphendula le-10 ms (ukusuka kwi-50 ms) kusetyenziswa uyilo olujikelezayo kabini, olulungele ukusetyenziswa kweenqwelo moya ezifuna ukusebenza ngokukhawuleza kakhulu4.

Into yokuphonononga: Ivalvu elungele ukubhabha yehlise ixesha lokuphendula nge-80% ngokusebenzisa i-geometry ye-coil ephuculweyo kunye nokunciphisa i-inductance4.

2. Cwangcisa ulwakhiwo lweValve kunye neeMechanics

Uyilo loomatshini luchaphazela ngokuthe ngqo isantya sokusebenza:

• IiPlungers eziKhaphukhaphu: Ukunciphisa ubunzima bokuhamba (umz., ii-titanium alloys) kunciphisa i-inertia, okuvumela intshukumo ekhawulezayo314.

• Ukulungiswa kwentwasahlobo okuchanekileyo: Ukudibanisa ukuqina kwentwasahlobo namandla emagnethi kuqinisekisa ukuvalwa ngokukhawuleza ngaphandle kokudubula kakhulu.

• Izikhokelo ze-Low-Friction: Imikhono yevalvu ekhazimlisiweyo okanye iingubo zeseramikhi zinciphisa ukunamathela, zibalulekile kwizicelo zemijikelo ephezulu1.

Umzekelo: Iivalvu zeCKD ziphucule impendulo ngama-30% kusetyenziswa ii-valve cores ezinciphileyo kunye nomthwalo wentwasahlobo ophuculweyo3.

3. Ukulungiswa kweSignali yoLawulo oluPhambili

Iiparameter zolawulo zichaphazela kakhulu impendulo:

• I-PWM (Ukuguqulwa kobubanzi bePulse): Ukulungisa imijikelo yomsebenzi kunye namaxesha okulibaziseka kuphucula ukuchaneka kokusebenza. Uphononongo luka-2016 lunciphise ixesha lokuphendula ukuya kwi-15 ms kusetyenziswa i-voltage ye-12V drive kunye ne-5% PWM duty8.

• Iisekethe ze-Peak-and-Hold: Iipulse zokuqala ezine-high voltage zikhawulezisa ukuvulwa kwevalvu, zilandelwe yi-low holding voltage ukunciphisa ukusetyenziswa kwamandla14.

Indlela Eqhutywa YidathaIndlela yokuphendula kumphezulu (RSM) ichonga umlinganiselo ofanelekileyo we-voltage, ukulibaziseka, kunye nomsebenzi, inciphisa ixesha lokuphendula ngama-40% kwiinkqubo zokutshiza kwezolimo8.

4. Ukukhethwa kwezinto ukuze zihlale ixesha elide kwaye zikhawuleze

Ukhetho lwezinto eziphathekayo lulungelelanisa isantya kunye nobomi obude:

• Ii-Alloys Ezingamelani Nokugqwala: Izindlu zentsimbi engagqwaliyo (316L) okanye zePEEK zimelana neendaba ezirhabaxa ngaphandle kokusebenza okonakeleyo114.

• IiCores eziPheleleyo eziphezulu: Izinto ze-Ferromagnetic ezifana ne-permalloy zonyusa ukusebenza kakuhle kwe-magnetic, zinciphisa ixesha lokunika amandla4.

5. Ulawulo lweNdalo kunye noLawulo lwaMandla

Izinto zangaphandle zifuna ukunciphisa:

• Ubonelelo lwaMandla oluZinzileyoUkuguquguquka kweVolthi >5% kunokulibazisa impendulo; abaguquli beDC-DC abalawulwayo baqinisekisa ukuhambelana314.

• Ulawulo lobushushu: Izinki zobushushu okanye iikhoyili ezizinzileyo kubushushu zithintela ukushukuma kokumelana kwiindawo ezinobushushu obuphezulu14.

Isicelo seShishini: Umatshini wokupakisha ufumene ixesha lokusebenza eliyi-99.9% ngokuhlanganisa abaqhubi abahlawulelwa ubushushu3.

Isifundo seTyala: Ivalvu ekhawulezayo kakhulu yezixhobo zonyango

Umenzi wezixhobo zonyango unciphise ixesha lokuphendula ukusuka kwi-25 ms ukuya kwi-8 ms ngo:

1. Ukusebenzisa ii-windings ze-dual-coil4.

2. Ukusebenzisa i-titanium plunger kunye nezikhokelo zokungqubana okuphantsi1.

3. Ukwamkela ulawulo lwe-PWM nge-voltage ye-14V peak8.
