Electronic fan resistance yogwira ntchito, kukana kwa ma fan pakompyuta ndizizindikiro zosweka.
Sinthani mphamvu yamagetsi kukhala kutentha
Kukaniza kwamagetsi kwa fan yamagetsi kumagwira ntchito makamaka posintha zomwe zikuchitika kukhala mphamvu ya kutentha.
The resistor in the electronic fan, yomwe imadziwikanso kuti thermistor, imakhala ndi gawo lalikulu pakuwunika kutentha kwa ma windings a motor.Pamene kutentha kwa injini yamagetsi kumawonjezeka, kukana kwa thermistor kumachepa.Kusintha kumeneku kumachitika chifukwa cha mgwirizano wolakwika wa kutentha kwapakati pakati pa kukana kwa thermistor ndi kutentha, ndiko kuti, pamene kutentha kumawonjezeka, mtengo wotsutsa udzachepa.Pamene mtengo wotsutsa ufika pa kutentha kwina, umatsikira pamtengo wina, zomwe zidzachititsa kuti dera lamtengo wapatali lizimitse ntchito, kotero kuti fani yamagetsi imasiya kugwira ntchito.Makinawa kwenikweni amateteza fani yamagetsi, kuteteza kuwonongeka chifukwa cha kutenthedwa.
Kuonjezera apo, mfundo yogwira ntchito yotsutsa imaphatikizaponso kutembenuka kwamakono.Zomwe zilipo panopa zikadutsa chotsutsa, chifukwa cha mphamvu ya thermoelectric ya resistor, kutentha kwapamwamba kwa resistor kudzakwera, ndipo mtengo wamakono udzasinthanso.Mwa kusintha pakali pano, magawo a kukana akhoza kusinthidwa, monga kutsutsa mtengo ndi mtengo wamakono, kuti akwaniritse kukhazikika kwa dera ndikuletsa zochitika zowonjezereka.
Pogwiritsira ntchito mafani amagetsi, kukana sikumangogwira ntchito yoteteza, komanso kumagwira nawo ntchito yoyendetsa liwiro komanso kutentha kwa magetsi.Mwachitsanzo, mu chowotcha chamagetsi chozizira pamagalimoto, magwiridwe antchito amawongoleredwa ndi njira zosiyanasiyana zowongolera (monga "thermistor switch + relay" control mode), ndipo liwiro la fan limangosinthidwa malinga ndi kutentha kwa madzi kapena liwiro.Njira yoyendetsera iyi sikuti imangowonjezera mphamvu ya fani yamagetsi, komanso imatsimikizira kuti ikugwira ntchito bwino.
Zizindikiro zazikulu za kulephera kwa mafani amagetsi ndi awa:
Kutulutsa mpweya sikungasinthidwe, ndiko kuti, kutuluka kwa mpweya wa fan sikungasinthidwe monga momwe akufunira.
Palibe zida za 1234, pali malo amodzi okha, kapena sagwira ntchito.
Zizindikirozi zikuwonetsa kuti chotsutsa cha fani yamagetsi chikhoza kuwonongeka, zomwe zimapangitsa kuti zisagwire ntchito bwino.Chotsutsacho chimagwira ntchito ngati chitetezo chamakono komanso chitetezo cha overvoltage m'derali, ndipo chikawonongeka, chingayambitse kutuluka kwa mpweya wa fan kuti zisathe kusinthidwa, kapena sizingagwire ntchito konse.Kuonjezera apo, pamene resistor ikugwira ntchito bwino, kukana kwake kulibe malire, pamene voteji yowonjezera imaposa mtengo wina, kukana kwake kudzakhala kochepa, kotero kuti dera ndilofupikitsa, kukakamiza fuseyi kuti iwotchedwe, imagwira ntchito. chitetezo chamagetsi.
Momwe mungayesere kukana kwamagetsi kwamagetsi molondola
Choyamba, udindo wa kukana kwa mafani amagetsi ndi zolakwika wamba
Kukaniza kwa fani yamagetsi ndi chimodzi mwazinthu zofunika kwambiri kuti ziwongolere kuthamanga kwagalimoto, zomwe zimazindikirika posintha mphamvu yamagetsi.Zolakwa zofala zimaphatikizapo kuwonongeka kwa kukana, kukhudzana kosauka kapena kutseguka, ndi zina zotero, zomwe zimapangitsa kuti galimoto isagwire ntchito bwino.
Chachiwiri, masitepe ndi njira zoyezera kukana
1. Chotsani magetsi ndikuchotsa chivundikiro cha fan kuti muwonetse kukana.
2. Gwiritsani ntchito multimeter kuti mugwire ndodo yoyezera mpaka kumapeto kwa kukana.Multimeter iyenera kukhazikitsidwa ku zida zoyezera kukana.Ngati kukana kuli kosinthika, ikani multimeter ku zida za rheostat kuti kukana kuwerengedwe bwino.
3. Werengani mtengo wotsutsa ndikuyerekeza ndi mtengo wa calibration wa mita yotsutsa.Ngati kuwerenga kuli pafupi ndi mtengo wa calibration, kukana ndi kwachilendo;Apo ayi kukana kumawonongeka.
Chachitatu, chitetezo
1. Poyesa kukana, magetsi ayenera kuchotsedwa poyamba kuti apewe ngozi.
2. Ngati multimeter imagwiritsidwa ntchito kuyeza kukana kosinthika, potozani chopingacho kuti chikhale chamtengo wapatali musanayambe kuyesa kuti musawononge zowonongeka.
3. Ngati kukhudzana ndi kukana sikuli bwino, gwiritsani ntchito chotsukira kuti muyeretse magawo okhudzana ndikuwona ngati zomangirazo zatsekedwa.
Iv.Mapeto
Pogwiritsira ntchito njira yomwe ili pamwambayi yoyezera kukana, tikhoza kudziwa mwamsanga komanso molondola ngati kukana kwa fani yamagetsi kwawonongeka, kuti m'malo mwake mulowe m'malo mwake ndikuonetsetsa kuti fani yamagetsi ikugwira ntchito.Panthawi imodzimodziyo, tikulimbikitsidwa kumvetsera chitetezo mukamagwiritsa ntchito mafani a magetsi komanso kuti musawagwiritse ntchito mopitirira muyeso kwa nthawi yaitali.
Chonde tiyimbireni ngati mukufuna zinthu zotere.
