M'magawa (ogawa) amitundu yambiri, ma rotor (slider) okhala ndi anti-interference resistors amagwiritsidwa ntchito.Werengani za zomwe slider yokhala ndi resistor ili, ndi ntchito ziti yomwe imagwira poyatsira, momwe imagwirira ntchito ndikugwira ntchito, komanso kusankha koyenera ndikusinthira gawo ili m'nkhaniyi.
Kodi resistor runner ndi chiyani ndipo imagwira ntchito yanji pogawa zoyatsira moto
Slider yokhala ndi resistor ndi rotor ya choyatsira cholumikizira cholumikizira ndi cholumikizira chopanda kulumikizana, chokhala ndi chopinga chosokoneza.
Dongosolo lililonse loyatsira ndi gwero lamphamvu la kusokoneza wailesi zomwe zimasokoneza kulandila mapulogalamu a wailesi m'magulu onse, m'galimoto momwemo komanso mgalimoto yodutsa pafupi.Zosokoneza izi zimamveka ngati kudina ndi kuphulika, kubwereza komwe kumawonjezeka ndi liwiro la injini.Kusokoneza kumapangidwa ndi zonyezimira zomwe zimachitika m'malo osiyanasiyana amagetsi amagetsi amagetsi oyatsira: m'mipata ya spark plugs ndi pakati pa zolumikizira pachivundikiro ndi slider ya wogawa.Phokoso likatsika, ma radiation ambiri a electromagnetic amapezeka - ndichifukwa chake kusokoneza kumamveka pafupifupi pamawayilesi onse.Komabe, kuwalako komwe kumapereka ma radiation otsika kwambiri, mphamvu yayikulu imatulutsidwa ndi zigawo zomwe zimagwirizanitsidwa ndi spark gap - mawaya apamwamba kwambiri omwe amakhala ngati tinyanga.
Kuti athane ndi zomwe zafotokozedwazo, zinthu zowonjezera zimalowetsedwa mu gawo lamphamvu kwambiri lamagetsi oyatsira - kugawidwa kapena kukana kokhazikika.Mawaya amphamvu kwambiri okhala ndi ma conductor osakhala achitsulo apakati amakhala ngati zokanira zogawidwa.Zotsutsa mu spark plugs ndi slider distributor zimakhala ngati zotsutsana kwambiri - izi zidzakambidwanso.
N'chifukwa chiyani kuyambitsidwa kwa resistor mu dera lapamwamba-voltage kumapangitsa kuchepa kwa kusokoneza?Chifukwa chake ndi chophweka.Pakakhala kusweka kwa spark gap, mafunde othamanga kwambiri amadutsa pa kondakitala wolumikizidwa ndi iyo, zomwe zimatsogolera kutulutsa kwa mafunde a wailesi ndi kondakitala uyu.Kuyika pakati pa spark gap ndi conductor wa resistor ndi kukana kwa zikwi zingapo ohms kusintha chithunzi: pamodzi ndi capacitances ndi inductances kuti conductors nthawi zonse, fyuluta yosavuta imapangidwa kuti amadula mkulu-pafupipafupi chigawo cha kusokoneza. .Pochita, kudula wathunthu sikuchitika, komabe, matalikidwe a mafunde othamanga kwambiri muwaya amachepa kwambiri, zomwe zimapangitsa kuti pakhale kuchepa kwapang'onopang'ono kwa kusokoneza kwa wailesi mu dera lapamwamba lamagetsi amagetsi.
Ngati tikunena kuti zonse zomwe tafotokozazi zimachokera ku slider distributor slider, ndiye kuti kusiyana kwa spark apa ndi kukhudzana kwa chivundikirocho ndi kukhudzana kwapafupi ndi slider, ndi mawaya othamanga kwambiri omwe amathamanga kuchokera ku koyilo kupita ku slider ndi kuchokera ku malumikizani kupita ku makandulo amachita ngati tinyanga.Choncho, apa resistor ali pakati kondakitala awiri, koma kupondereza kwambiri kusokoneza kumachitika pa waya kuchokera koyilo, ndi kupondereza kusokoneza pa mawaya kandulo kumachitika chifukwa kukana mawaya okha ndi resistors anamanga mu makandulo.
Wogawa moto ndi malo a slider mmenemo
Ichi ndichifukwa chake chotsutsachi chimatchedwa anti-interference (kapena kungopondereza).Komabe, kuwonjezera pakulimbana ndi kusokoneza wailesi, resistor imagwira ntchito zina zingapo:
● Kupewa (kapena kuchepetsa kuchulukira) kwa kutenthedwa kwa zolumikizana ndi chivundikiro chogawa ndi slider yokha;
● Kuchepetsa kuthekera kwa kuwonongeka kwa magetsi kuchokera kuzinthu zina zamphamvu kwambiri;
● Kuchulukitsa moyo wautumiki wa makandulo ndi zigawo zina;
● Kuwonjezeka kwa nthawi ya kutuluka kwa spark, zomwe nthawi zina zimawonjezera kukhazikika kwa injini.
N’chifukwa chiyani zonsezi zikuchitika?Chifukwa chake ndi kukana kwa magetsi, zomwe zimapanga resistor.Chifukwa cha kukana kwa dera lapamwamba-voltage, pamene kukhetsa kumayenda, mphamvu yamakono imachepa - ndikwanira kuti kuwala pakati pa ma electrode a makandulo kuyatsa chisakanizo choyaka moto, koma osakwanira kusungunuka kwachitsulo cha m'deralo. ma electrodes ndi ma contacts mu distribuerar.Panthawi imodzimodziyo, mphamvu yosungidwa mu koyilo imakhalabe yofanana, komabe, chifukwa cha kukana kowonjezereka kwa dera, sikuperekedwa ku makandulo nthawi yomweyo, koma kwa nthawi inayake - izi zimabweretsa kuwonjezeka kwa magetsi. nthawi yotulutsa, yomwe imatsimikizira kuyatsa kodalirika kwa osakaniza mu masilinda.
Choncho, resistor m'modzi yekha mu slider wa poyatsira distribuerar amachita ntchito zingapo zomwe zimawonjezera mphamvu ya injini ndi chitonthozo cha galimoto.
Mapangidwe ndi mawonekedwe a slider okhala ndi resistor
The slider (rota) ndi resistor tichipeza angapo mbali: mlandu wotayira, awiri rigidly anakonza kukhudzana (chapakati, kupumula pa ember mu distributor chivundikirocho, ndi mbali imodzi) ndi cylindrical resistor ili mu recess wapadera.Thupi limapangidwa ndi zinthu zoteteza magetsi, zomwe zimalumikizana nthawi zambiri zimakhazikika pa izo ndi ma rivets.Ma mbale a Springy amapangidwa pamalumikizidwe, pomwe chopingacho chimamangidwa.M'munsi mwa thupi la slider, njira yojambulidwa imapangidwira kukonza choyatsira pa shaft.
Malinga ndi njira yokhazikitsira resistor, pali mitundu iwiri ya slider:
● Ndi chopinga chosinthika;
● Ndi chotsutsa chosasinthika - gawolo limadzazidwa ndi malo osungiramo malo apadera opangidwa ndi epoxy resin kapena vitreous.
Slider yokhala ndi resistor
Othamangawo amagwiritsa ntchito zopinga zamphamvu zamapangidwe apadera okhala ndi ma terminals, opangidwa kuti aziyika pakati pa ma springy contacts.M'magalimoto apanyumba, zotsutsana ndi 5.6 kOhm zimagwiritsidwa ntchito nthawi zambiri, koma zotsutsana ndi 5 mpaka 12 kOhm zimapezeka muzitsulo zosiyanasiyana.
Kutengera ndi mtundu wa ogawa, chowongoleracho chimangoyikidwa pa shaft yogawa (nthawi zambiri mbali zotere zimakhala zooneka ngati T), kapena zomangika ndi zomangira ziwiri pa chowongolera nthawi yoyatsira (zigawo zotere zimapangidwa ngati silinda yathyathyathya) .Pazochitika zonsezi, chotsutsacho chimayikidwa kunja kwa slider, yomwe imatsegula mwayi wowunika ndipo, ngati n'kotheka, m'malo mwake.
Mafunso okhudza kusankha ndikusintha slider yokhala ndi resistor
Chotsutsa chomwe chimayikidwa mu slider chimakhala ndi katundu wambiri wamagetsi ndi makina, kotero pakapita nthawi zimatha kulephera - kutentha kapena kugwa (kuphwanyika).Monga lamulo, kuwonongeka kwa resistor sikulepheretsa injini, koma kumasokoneza kwambiri kugwira ntchito kwake - injini sichipeza mphamvu zonse, imayankha bwino poyendetsa gasi, "troit", amawombera, ndi zina zotero. dutsa pa chowotcha chowotcha kapena chogawanika, kotero makina oyatsira akupitilizabe kugwira ntchito, koma ndi zophwanya komanso mopanda bwino.Zizindikiro zotere zikawoneka, choyamba muyenera kuchotsa chivundikiro chogawa (izi ziyenera kuchitika pokhapokha injini itayimitsidwa ndikuchotsa chotengera ku batri), kumasula ndikuwunika chowongolera.Ngati slider ndi wamba, ndiye kuti ikhoza kuchotsedwa popanda zida, ndipo ngati gawolo likugwirizana ndi chowongolera nthawi yoyatsira, ndiye kuti zomangira ziwiri ziyenera kuchotsedwa ndi screwdriver.
Ngati, poyang'ana chopingacho, palibe zizindikiro zakunja za kusagwira ntchito kwake (sikuwotchedwa kapena kusweka), kapena kutsutsa kuli ndi pawiri, ndiye kuti muyenera kuyang'ana kukana kwake ndi tester - iyenera kukhala pamtunda wa 5-6 kOhm (kwa magalimoto ena - mpaka 12 kOhm, koma osachepera 5 kOhm).Ngati kukana kumakhala kosakwanira, ndiye kuti resistor ndi yolakwika ndipo iyenera kusinthidwa.Gawo la mtundu womwewo ndi kukana liyenera kutengedwa kuti lilowe m'malo - iyi ndiyo njira yokhayo yotsimikizira kuti chopingacho chidzagwera m'malo mwake ndipo dongosolo lonse lidzagwira ntchito bwino.Kusintha kotsutsa kumatsika ndikungochotsa gawo lakale (ndikosavuta kulichotsa ndi screwdriver) ndikuyika yatsopano.Ngati resistor wodzazidwa ndi pawiri, ndiye muyenera kusintha slider lonse - galimoto zoweta, m'malo amenewa ndalama makumi angapo rubles.
Slider yokhala ndi zodzaza
WotsutsaCholetsa chosinthika cha slider
Nthawi zambiri, eni galimoto amaika ma jumpers a waya m'malo mwa resistors - ndizoletsedwa kuchita izi.Kusowa kwa resistor kumawonjezera kuchuluka kwa kusokonezedwa kwa wailesi ndipo kumatha kusokoneza magwiridwe antchito a makina oyaka (kuphatikiza kutsogolera kuvala kwambiri kwa kulumikizana kwa slider ndi chivundikiro chogawa, ndi ma electrode a spark plugs).Sitikulimbikitsidwanso kusintha slider ndi resistor kuti slider yosavuta mumakina oyatsira okhala ndi mawaya othamanga kwambiri a zero resistance.Mitundu ndi mitundu yokhayo ya masilayidi omwe wopanga amayatsa ndioyenera kugwiritsidwa ntchito m'malo.
Ndi kusankha koyenera ndi kusinthidwa kwa slide ndi chotsutsa (kapena chotsutsa chokha), njira yoyatsira idzagwira ntchito modalirika komanso ndi "kuipitsa" kochepa kwa mpweya wa wailesi.
