Momwe mungayang'anire koyilo yamagetsi ndi multimeter

Zamkatimu

Koyilo cha poyatsira mukalephera, injini yamagalimoto amakono imasiya kuyambika. Kuzindikira kwamagalimoto kwamagalimoto sikuti nthawi zonse kumapangitsa kuti coil iwonongeke; Zikatero, njira yakale komanso yotsimikizika yoyeserera pogwiritsa ntchito chida chaponseponse (multimeter) mumayeso oyeserera a ohmic samalephera.

Cholinga cha koyilo yoyatsira ndi mitundu yake

Choyatsira poyatsira (chomwe chimadziwikanso kuti bobbin) chimasintha mphamvu yamagetsi kuchokera pa batire yomwe ili pa board kupita pachimake pamphamvu yamagetsi, kuyigwiritsa ntchito pazipilala zomwe zimayikidwa muzipilala, ndikupanga mphamvu yamagetsi mumphako wa mpweya. Kutulutsa kotsika kwamagetsi kumapangidwa mu chopper (wogulitsa), switch (poyatsira amplifier) ​​kapena unit control unit (ECU).

Kuti magetsi asokonezeke chifukwa cha kutha kwa mpweya wa 0,5-1,0 mm, pamafunika mpweya wokwanira ma kilovolts osachepera 5 (kV) pa 1 mm ya kusiyana, i.e. Mphamvu yamagetsi yamagetsi yosachepera 10 kV iyenera kugwiritsidwa ntchito pamakandulo. Kuti mukhale odalirika kwambiri, poganizira za kutayika kwamagetsi pama waya olumikizira ndi zowonjezera zowonjezera, magetsi omwe amapangidwa ndi koyilo amayenera kufikira 12-20 kV.

Chenjezo! Kutulutsa kwamphamvu kwamagetsi kochokera koyilo yamagetsi kumakhala koopsa kwa anthu ndipo kungayambitsenso magetsi! Kutuluka kumakhala koopsa makamaka kwa anthu omwe ali ndi matenda amtima.

Chipangizo choyatsira coil

Coil yoyatsira ndiyosinthira mosintha ndi ma windings a 2 - otsika-magetsi ndi othamanga kwambiri, kapena autotransformer momwe ma windings onse amalumikizana, otchedwa "K" (thupi). Chozungulitsira choyambirira chimamangirizidwa ndi waya wamkuwa wothira m'mimba mwake wa 0,53-0,86 mm ndipo imakhala ndi kutembenuka 100-200. The kumulowetsa yachiwiri wamangidwa ndi waya ndi awiri a 0,07-0,085 mamilimita ndipo muli kutembenuka 20.000-30.000.

Zambiri pa mutuwo:

Injini ikuyenda ndipo camshaft itembenuka, makina amagetsi omwe amagawika amatsekedwa motsatizana ndikutsegula olumikizanawo, ndipo pakatsegula, kusintha komwe kukukulira koyilo koyatsira malinga ndi lamulo la kupatsidwa mphamvu kwamagetsi kumapangitsa mkulu voteji.

Mu njira yomweyi, yomwe idagwiritsidwa ntchito mpaka zaka 90, kulumikizana kwamagetsi pamadongosolo otsegulira nthawi zambiri kumawotchera, ndipo mzaka 20-30 zapitazi, opanga zida zamagetsi asintha ma breaker amagetsi ndi ma swichi odalirika, komanso magalimoto amakono, opaleshoniyi koyilo yoyatsira imayang'aniridwa ndi makina oyang'anira injini, momwe mulinso chosinthira chomangidwira.

Nthawi zina chosinthiracho chimakhala chophatikizika ndi koyilo yoyatsira, ndipo ngati yalephera, muyenera kusintha chosinthira limodzi ndi koyilo.

Mitundu poyatsira koyilo

Pali mitundu ingapo yamafuta oyatsira omwe amagwiritsidwa ntchito mgalimoto:

  • wamba ku dongosolo lonse poyatsira;
  • mapasa wamba (a injini 4-yamphamvu);
  • ambiri patatu (a injini 6-yamphamvu);
  • payekha pa silinda iliyonse, iwiri.

Mapasa wamba amaphatikizana ndi ma katatu nthawi imodzi amatulutsa zokometsera m'miyendo yomwe imagwira ntchito chimodzimodzi.

Kuwona za koyilo yoyatsira ndi multimeter

Yambani kuwona koyilo yoyatsira ndi "kupitiriza" kwake, mwachitsanzo. kuyeza kukana kwa waya kumulowetsa.

Kuwona ma coil wamba oyatsira

Kuwona koyilo kuyenera kuyamba ndikamayambira. Kukaniza koyenda, chifukwa chakuchepa kwakanthawi kwa waya wakuda, ndiyotsikiranso, pakati pa 0,2 mpaka 3 Ohm, kutengera mtundu wa koyilo, ndipo imayesedwa pamalo osinthira a multimeter "200 Ohm".

Mtengo wotsutsana umayesedwa pakati pa malo "+" ndi "K" a koyilo. Mutayitanitsa olumikizana nawo "+" ndi "K", muyenera kuyeza kukana kwa koyilo kwamphamvu kwambiri (komwe switch ya multimeter iyenera kusinthidwa kupita ku "20 kOhm" malo) pakati pa malo "K" ndi Kutulutsa kwa waya wapamwamba kwambiri.

Kuti mulumikizane ndi malo othamanga kwambiri, gwirani kafukufuku wa multimeter kulumikizana ndi mkuwa mkati mwamphamvu yolumikizira waya. Kukaniza kwa kutsika kwamphamvu kwambiri kuyenera kukhala mkati mwa 2-3 kOhm.

Kupatuka kwakukulu kwa kukana kwamtundu uliwonse wa koyilo kuchokera koyenera (mwakuya kwambiri, dera lalifupi kapena dera lotseguka) kumawonetsa kuwonongeka kwake komanso kufunika kosintha.

Kuwona ma coil awiri oyatsira

Kuyesa ma coil awiri oyatsira ndikosiyana komanso kumakhala kovuta kwambiri. M'malo amtunduwu, zotsogola zoyambira nthawi zambiri zimatulutsidwa kuti zilumikizidwe ndi pini, ndipo kuti mupitirize, muyenera kudziwa zikhomo za cholumikizira chomwe chalumikizidwa.

Zambiri pa mutuwo:
  Stepper motor: magwiridwe antchito, mtundu ndi mtengo

Pali malo awiri okwera pamagetsi amtundu wama coil, ndipo kumalizirako koyenera kuyenera kulumikizidwa polumikizana ndi ma probes a multimeter okhala ndi malo onse okhala ndi ma voliyumu ambiri, pomwe kulimbana komwe kumayesedwa ndi multimeter kumatha kukhala kocheperako kuposa koyilo wamba wonse system, ndikudutsa 4 kΩ.

Momwe mungayang'anire coil yoyatsira ndi multimeter ya Renault Logan - Logan Yanga

Kuwona ma coil oyatsira

Chifukwa chakusowa kwa tinthu tating'onoting'ono tomwe timayatsa, kuphatikiza pakulephera kwayokha (komwe kumayang'aniridwa ndi multimeter monga tafotokozera pamwambapa), kungakhale kusokonekera kwa zowonjezera zowonjezera zomwe zimapangidwira. Chotsulirachi chimatha kuchotsedwa mosavuta pa coil, pambuyo pake kukana kwake kuyenera kuyezedwa ndi multimeter. Mtengo wabwinobwino wokana ndi 0,5 kΩ mpaka ma k several angapo, ndipo ngati multimeter ikuwonetsa dera lotseguka, cholumikizira chimakhala cholakwika ndipo chimayenera kusinthidwa, pambuyo pake kuthetheka kumawonekera.

Mafunso ndi Mayankho:

Momwe mungayang'anire koyilo yamoto ya VAZ ndi Multimeter? Pachifukwa ichi, coil ndiyosavuta kumasula. Kukaniza kumayezedwa pamakona onse awiri. Kutengera mtundu wa koyilo, kulumikizana kwa ma windings kudzakhala m'malo osiyanasiyana.

Momwe mungayesere koyilo ndi multimeter? Choyamba, kafukufukuyo amalumikizidwa ndi mafunde oyambira (kukana mkati mwake kuyenera kukhala mkati mwa 0.5-3.5 ohms). Zofananazo zimachitika ndi mafunde achiwiri.

Kodi ndingayang'ane koyilo yoyatsira? Mu garaja, mutha kuyang'ana pawokha poyatsira moto ndi choyatsira chamtundu wa batri (kupanga zakale). Makoyilo amakono amafufuzidwa pokhapokha pa ntchito ya galimoto.
