Galimoto yamagetsi yamagetsi imayendetsedwa ndi chipangizo chapadera chomwe chili pa thupi lake - retractor (kapena traction) relay.Werengani zonse za ma relay retractor, kapangidwe kake, mitundu ndi mfundo zogwirira ntchito, komanso kusankha koyenera ndikusinthanso ma relay pakagwa kuwonongeka.
Kodi starter retractor relay ndi chiyani?
Starter retractor relay (relay traction) - msonkhano wamagalimoto oyambira magetsi;Solenoid yophatikizidwa ndi gulu lolumikizana, lomwe limapereka kulumikizana kwa mota yoyambira ku batri komanso kulumikizana ndi makina oyambira ku korona wakuwuluka poyambira injini.
The retractor relay amalowa mu makina ndi magetsi mbali sitata, kulamulira ntchito olowa awo.Node iyi ili ndi ntchito zingapo:
- Kupereka kwa drive drive (bendix) ku mphete ya giya ya flywheel poyambitsa injini ndikuigwira mpaka kiyi yoyatsira itatulutsidwa;
- Kulumikiza injini yoyambira ku batri;
- Bwezerani galimoto ndikuzimitsa choyambira pamene kiyi yoyatsira itulutsidwa.
Ngakhale kuti traction relay imagwira ntchito ngati gawo loyambira, ndi gawo losiyana lomwe limagwira ntchito yofunika kwambiri pakugwira ntchito kwa injini yoyambira.Kuwonongeka kulikonse kwa chipangizochi kumapangitsa kukhala kovuta kwambiri kuyambitsa injini kapena kupangitsa kuti zisatheke, kotero kukonzanso kapena kusinthidwa kuyenera kuchitika posachedwa.Koma musanagule relay yatsopano, muyenera kumvetsetsa mitundu yake, mawonekedwe ake ndi mfundo zake
Mapangidwe, mitundu ndi mawonekedwe a retractor relay
Pakali pano, oyambitsa magetsi amagwiritsa ntchito ma retractor omwe amapangidwa mofanana ndi momwe amagwirira ntchito.Chigawochi chili ndi zida ziwiri zolumikizidwa - cholumikizira mphamvu ndi solenoid yokhala ndi zida zosunthika zomwe zimayatsa (ndipo nthawi yomweyo zimabweretsa bendix ku flywheel).
Maziko a mapangidwewo ndi cylindrical solenoid yokhala ndi ma windings awiri - retractor yaikulu ndi kusunga bala limodzi pamwamba pake.Kumbuyo kwa solenoid ndi nyumba yolumikizirana yopangidwa ndi zida zolimba za dielectric.Maboti olumikizana ali kumapeto kwa khoma la relay - awa ndi ma terminals apamwamba omwe choyambitsa chimalumikizidwa ndi batri.Maboti amatha kukhala chitsulo, mkuwa kapena mkuwa, kugwiritsa ntchito kulumikizana kotereku kumachitika chifukwa cha mafunde apamwamba mumayendedwe oyambira poyambira injini - amafika 400-800 A kapena kupitilira apo, ndipo ma terminals osavuta okhala ndi pano amatha kusungunuka.
Chithunzi cha mawaya a retractor relay ndi cholumikizira chowonjezera komanso chowonjezera choyambira
Pamene mabawuti olumikizana atsekedwa, mapindikidwe a retractor amafupikitsidwa (magawo ake oyandikana), motero amasiya kugwira ntchito.Komabe, mafunde otsekereza akadali olumikizidwa ndi batire paketi, ndipo mphamvu ya maginito yomwe imapanga ndi yokwanira kusunga zida zotetezedwa mkati mwa solenoid.
Pambuyo poyambira bwino injini, fungulo loyatsira limabwerera kumalo ake oyambirira, chifukwa chake chigawo chozungulira chimadutsa - mu mphamvu ya maginito yozungulira solenoid imasowa ndipo armature imakankhidwira kunja kwa solenoid. masika, ndipo ndodo imachotsedwa pazitsulo zolumikizana.Kuyendetsa koyambira kumachotsedwa ku flywheel korona ndipo choyambira chimazimitsidwa.Ma traction relay ndi choyambira chonse amasamutsidwa pamalo okonzeka kuyambitsa injini yatsopano.
Nkhani zakusankha, kukonza ndikusintha relay retractor
Ma traction relay amakhala ndi katundu wambiri wamagetsi ndi makina, kotero pali kuthekera kwakukulu kwa kulephera kwake ngakhale atagwira ntchito mosamala.Kusagwira ntchito kwa chipangizochi kumatsimikiziridwa ndi zizindikiro zosiyanasiyana - kusakhalapo kwa kugogoda pamayendedwe oyambira pomwe kuyatsa kumayatsidwa, kutembenuka kofooka kwa choyambira pomwe batire imayimbidwa, "chete" choyambira pomwe kuyendetsa. kupereka akuthamanga, ndi zina.Komanso, malfunctions amadziwika pamene relay akuthamanga - kawirikawiri pali yopuma ma windings, kuwonjezeka kukana mu dera mphamvu chifukwa choyaka ndi kuipitsidwa kwa kulankhula, etc. Nthawi zambiri, mavuto odziwika ndi ovuta kapena zosatheka kuthetsa (monga monga yopuma mu retractor kapena kusunga windings, kusweka kwa bawuti kukhudzana, ndi ena), kotero n'zosavuta ndi zotchipa kwathunthu m'malo mopatsirana.
Chida chachikulu cha choyambira chamagetsi ndi malo a retractor relay mmenemo
Mitundu ndi mitundu yokhayo ya ma retractor omwe amafotokozedwa ndi wopanga magalimoto ndiye ayenera kusankhidwa kuti alowe m'malo.Kugula kuyenera kupangidwa ndi manambala amndandanda - iyi ndi njira yokhayo yosinthira node molimba mtima ndikupangitsa kuti choyambitsacho chizigwira ntchito bwino.Ndizovuta kapena zosatheka kukhazikitsa mtundu wina (chifukwa cha miyeso yosiyana), ndipo ngati izi zingatheke, woyambitsayo sangagwire ntchito bwino kapena sangagwire ntchito yake yaikulu.
Kuti mulowe m'malo mwa relay, choyambira chamagetsi chiyenera kuchotsedwa mu injini ndi kupasuka, nthawi zambiri pogwiritsa ntchito chida chapadera.Mukayika relay yatsopano, maulumikizidwe amagetsi ayenera kupangidwa mosamala - mawaya amachotsedwa kale ndikupotozedwa, powakonza pamaterminals, kudalirika kuyenera kutsimikizidwa poletsa kutentha ndi kutentha.Ntchito zonse zimachitidwa bwino motsatira malangizo omwe amaperekedwa ndi automaker mu malangizo okonza ndi kukonza galimoto.
M'tsogolomu, traction relay, monga choyambira chokha, chimangofunika kuyang'anitsitsa nthawi ndi nthawi ndi kutsimikizira motsatira malamulo osamalira.Ndi kusankha koyenera ndi kusinthidwa, chipangizochi chidzagwira ntchito modalirika komanso moyenera, kuonetsetsa kuti injiniyo imayamba molimba mtima.
