Kuchita bwino kwamphamvu kwakhala chinthu chofunikira kwambiri pakupanga mafakitale a 2024. Zinthu zingapo zimayendetsa izi kusuntha: Ma Valvel-Ourcy-Enkoid Varves amapereka njira yosinthira. Zipangizo zapamwamba izi zimachepetsa kugwiritsa ntchito mphamvu mpaka 80%, kutsitsa ndalama zogwirira ntchito pogwiritsira ntchito zolinga zantchito pothandizira zolinga za owononga.
Makandulo Ofunika
- Mphamvu yopulumutsa mphamvu ya Enelenid imagwiritsa ntchito mpaka 80% mphamvu zochepa. Izi zimathandiza mafakitale amasunga ndalama zambiri.
- Maukali amenewa amagwira bwino ntchito komanso yatha nthawi yayitali. Amafunikira kukonza pang'ono ndikukhalabe wodalirika kwa nthawi yayitali.
- Kugwiritsa ntchito mavuvu opulumutsa mphamvu kumathandizira mafakitale kutsatira malamulo otetezedwa. Zimathandiziranso zolinga zapadziko lonse lapansi.
Kodi ma valves oyenda bwino a solenoid?
Tanthauzo ndi magwiridwe antchito
Ma Varves Ogwiritsa Ntchito Magetsi ndi zida zapamwamba zopangidwa kuti ziziwongolera zakumwa kapena mpweya pomwe mukuchepetsa kugwiritsa ntchito mphamvu. Ma uvuni amenewa amaligwiritsa ntchito pogwiritsa ntchito coil electromagnetic yomwe imayambitsa kutsegulanso valavu. Mosiyana ndi ma valves achikhalidwe cha solenoid Zinthu izi zimachepetsa mphamvu zomwe zimafunikira kuti azikhala ndi udindo, kuwapangitsa kukhala abwino pantchito zomwe zimakuthandizani.
Maukadaulo aukadaulo amatanthauzira magwiridwe awo. Mwachitsanzo:

Kusiyana kwa Mavalidwe Achikhalidwe a Solenoid
Ma Valvel-Ogwira bwino Mavavu amasiyana kwambiri ndi mitundu yazikhalidwe muzochita zawo ndi mphamvu zake. Zikhalidwe zachikhalidwe cha AC Sofikoid imafuna nsonga yamphamvu yamakono kuti itseguke koma imawononga mphamvu zocheperako kuti mukhale otseguka. Mosiyana ndi izi, DC Solenoid Valves ikufunanso zamakono, zomwe zimayambitsa kugwiritsa ntchito mphamvu zapamwamba. Mapangidwe oyenda bwino, monga matsenga a solalekoid solekoid, gwiritsani ntchito maginito okhazikika kuti agwire Valande, kuthetsa kufunika kofunikira mphamvu yopitilira. Izi zopanga zimachepetsa kumwa kwa mphamvu pofika 95% pambuyo pa kutsegula, kupereka ndalama zotsika mtengo.
Kufunika Kwamakono
Kupanga kwamakono kumadalira mphamvu zamagetsi zolimbitsa thupi kuti atseke njira ndikuchepetsa ndalama zogwirira ntchito. Mavevuwa amapulumutsa mphamvu pogwira ntchito pang'ono ngati ma wtts 0,5, omwe amatha kutanthauzira kukhala madola mamiliyoni a ndalama zosungira maofesi pogwiritsa ntchito mavalidwe osiyanasiyana. Kuphatikiza apo, amathandizira mafakitale amakumana ndi zingwe zazikulu ndi zolinga zokhazikika. Pochepetsa kugwiritsa ntchito mphamvu, mavuvuwo osati mtengo wotsika yekha komanso amalimbikitsa kukhala ndi udindo wa chilengedwe, wokondweretsa kwa otenga nawo mbali.
Ubwino wopanga zomera
Kusunga mphamvu ndi kuchepetsa mtengo
Ma Vallod-Ogwira bwino Maulamuliro amapereka ndalama zambiri, zomwe zimatanthauzira mwachindunji kuti zisawonongeke mitengo. Mavesi awa amagwiritsa ntchito matekinoloje apamwamba, monga kumenyana ndi dontho, kuti achepetse kugwiritsa ntchito mphamvu mpaka 80%. Kuchita bwino kumeneku kumapangitsa kuti ndalama zolipirira ndalama zoyendetsera ntchito, ndi maofesi ena omwe amapereka ma euro masauzande angapo omwe adapulumutsidwa pachaka. Phunziro lolemba za SBIR lomwe limapanga mapulani a SBIR omwe maamwachi amatha kukwaniritsa mphamvu za 20-25%, zomwe zingakhalepo kwa ndalama za $ 400 mpaka $ 500 miliyoni kwa US Opanga.
