M'magawo monga zamagetsi zamagalimoto ndi kuwongolera mafakitale, mawaya a AVS ndi AVSS amagwiritsidwa ntchito kwambiri ma conductor otsekeredwa, koma mainjiniya ambiri nthawi zambiri amasokoneza ukadaulo wa awiriwa. Nkhaniyi ithetsa kusiyana kwakukulu pakati pa mitundu iwiriyi ya mawaya kuchokera kuzinthu, magwiridwe antchito mpaka mawonekedwe ogwiritsira ntchito, ndikuthandizani kusankha molondola mwa kuphatikiza milandu yeniyeni.
1.Kusiyana kwamapangidwe
Onsewa ndi a PVC insulated mawaya, koma pali kusiyana koonekeratu pamapangidwe a zosanjikiza zotchingira, zomwe ndiye gwero la kusiyana kwa magwiridwe antchito.
Mtengo wa AVS
Makondakitala nthawi zambiri amakhala mawaya ofewa ofewa amkuwa, okhala ndi ma diameter a waya kuyambira 0.3 mpaka 2.0mm², mogwirizana ndi muyezo wa JIS C 3306.
Mtengo wa AVSS
Chipinda chamkati cha PVC chofewa chimatsimikizira kusinthasintha, pamene gawo lakunja la PVC lolimba limapangitsa chitetezo. Zolemba za conductor ndizofanana ndi za AVS.
2.Mawonekedwe ogwiritsira ntchito ndi zochitika zenizeni
①Mtengo wa AVS: Mtengo-kusankha kothandiza pa kutentha kwabwinobwino komanso kutsika kwamagetsi
Mawaya apakati pagalimoto: Mu projekiti ya dashboard wiring harness ya galimoto yophatikizika ya mtundu wina wake, ya zida zotsika-zochepa mphamvu monga -makina omvera mugalimoto (power 45W, 3.75A yomwe ikugwira ntchito pano) ndi kuyatsa kozungulira (single channel power 10W, 0.83mm 0.83Awaya yosankhidwa ngati AVs² yamakono), 0.83mm ya AV73 zida zopangira ma wiring. Malinga ndi mawaya a mkuwa-onyamula katundu wake, mphamvu yonyamulira-waya wa 0.75mm² ndi 6-9A, ndipo mphamvu yeniyeni ya chipangizocho ndi 41%-62% yokha ya mphamvu yonyamulira panopa, yomwe ikugwirizana ndi zofunikira zochepetsera ntchito yanthawi yayitali. Chochitikachi chili mkati mwa cockpit, ndi kutentha kozungulira komwe kumakhazikika pa -10 digiri mpaka 60 digiri, yopanda kuipitsidwa ndi mafuta, ndipo imakhala ndi zofunika kwambiri pakuwongolera mtengo. Chingwe chomaliza cha mawaya chinadutsa mayeso a kugwedezeka kwa maola 1000 pa 10-50Hz popanda cholakwika chilichonse. Kukana kwa kutchinjiriza kwa wosanjikiza wa insulation kunakhalabe pamwamba pa 1000MΩ, ndipo panalibe chodabwitsa chokalamba. Poyerekeza ndi kugwiritsa ntchito mawaya a AVSS, mtengo wazinthu udachepetsedwa ndi 15%.
②Mtengo wa AVSS: Chitsimikizo chodalirika cha-malo otentha kwambiri ndi{1}}mafuta ambiri
Chikwama cha chipinda cha injini yamagalimoto: Pa waya wolumikizira sensa yamafuta mugawo la injini yagalimoto inayake yamalonda, waya wa 1.0mm² AVSS adasankhidwa. Derali nthawi zonse limakhala ndi{2}}kutentha kwambiri kwa madigiri 80 mpaka 100 . Panthawi idling, kutentha kwa m'deralo kumatha kufika madigiri 105, ndipo pali chiopsezo chotaya mafuta a injini (mafuta amchere Ochepera kapena ofanana ndi 5mg/cm²). Mphamvu yapano{{9}yonyamula mawaya a copper a 1.0mm² m'malo a digirii 105 ndi 7.2A, ndipo mphamvu yogwira ntchito ya sensayo ndi 4.5A, yomwe ndi 62.5% yokha ya mphamvu-yakunyamulira, ikukwaniritsa zomwe zasankhidwe-zotentha kwambiri. Pambuyo pogwira ntchito mosalekeza pa digiri ya 105 kwa maola 3,000, makulidwe a waya wa AVSS adatsika kuchokera pa 0.35mm mpaka 0.33mm, ndi kutsika kwa 5.7% yokha. Mosiyana ndi izi, makulidwe amtundu wamtundu womwewo wa waya wa AVS adatsika ndi 0.1mm pamikhalidwe yomweyi, ndikuchepetsa kwa 28.6%. Kuphatikiza apo, wosanjikiza wake wakunja wa PVC wolimba wadutsa mayeso a 5,000 friction (pakukakamiza kwa 5N), ndi kuvala kwa 0.01mm kokha, motero amapewa kuwonongeka kwa kutchinjiriza komwe kumachitika chifukwa cha mikangano pakati pa ma wiring harness ndi zida za injini.
③Mlandu wopanda pake: Mtengo wosankha molakwika
Kuti achepetse ndalama, malo ena okonzera magalimoto analowa m'malo mwa mawaya pafupi ndi malo otumizira magalimoto (-kutentha kwanthawi yayitali kwa madigiri 90 mpaka 100, zomwe zimabweretsa chiwopsezo chachikulu cha kutayikira kwamafuta a hydraulic) ndi mawaya a 1.0mm² AVS m'malo mwa mawaya a AVSS. Mphamvu yapano{{5}yonyamula mawaya a 1.0mm² AVS pa digirii 100 ndi 5.4A yokha, pomwe mphamvu yonyamulira magetsi ndi 4.8A, yomwe yafika pa 88.9% ya mphamvu-yonyamulira panopo ndipo ili pafupi ndi mtengo wofunikira kuti-igwire ntchito yonse. Atagwiritsidwa ntchito kwa miyezi itatu (pafupifupi maola 500), chifukwa cha kutentha kwa kutentha kwa kutentha kwa 50% pa kutentha kwa madigiri 10 aliwonse, kutsekemera kwa waya wa AVS kunasonyeza kufewetsa kwambiri (kuuma kwatsika kuchokera ku 85Shore D mpaka 60Shore D), kusweka, ndi kukana kwa insulation kunatsika kuchokera pa 1M0M Ω0 mpaka 1M Ω0 koyamba. Izi zidapangitsa kuti chizindikiro cha sensor yopatsirana chisokonezeke, zomwe zidapangitsa kuti galimotoyo ikhale yolakwika (yolakwika P0700). Pambuyo posintha ndi mawaya a AVSS ovomerezeka, cholakwikacho chidathetsedwa. Mtengo wosinthira magawo, 8,000 yuan, ndalama zogwirira ntchito, 2,000 yuan ndi kutayika kwa nthawi yopumira magalimoto, zokwana 20,000 yuan, zidachitika chifukwa chosankha molakwika.
3.Zothandiza Kalozera pakusankha
Poganizira zinthu zazikulu zitatu za kutentha, kuipitsidwa kwa mafuta ndi mtengo wake wonse: AVSS imakondedwa m'malo okwera-otentha komanso apamwamba-monga mafuta (monga zipinda zamainjini ndi zida zamagetsi), pomwe AVS ndiyoyenera kutentha kwanthawi zonse ndi kuuma (monga zamkati zamagalimoto ndi zamagetsi zapakhomo).
Nthawi yomweyo, chonde dziwani:
Sankhani waya awiri malinga ndi katundu panopa. Pazida zomwe zimagwira ntchito kwa nthawi yayitali, sankhani 60% ya mphamvu zonyamulira-pakali pano; pazida zomwe zimagwira ntchito kwakanthawi kochepa, sankhani 60% mpaka 100%.
Zingwe zamawaya zamagalimoto ziyenera kusankhidwa motsatira ma code amtundu kuti zithandizire kuzizindikiritsa pakakonzedwanso pambuyo pake.
Kufanana pakati pa-kunyamula kwa kondakitala ndi kuchuluka kwa mzere kumatsimikiziridwa kudzera m'mapindikira otulutsa utsi ndi zida zoyeserera kuti zitsimikizire chitetezo ndi kudalirika kwa zomwe zasankhidwa.
