- Kodi nchifukwa ninji ma motors akutha kwambiri tsopano kuposa kale?
Chifukwa chakukula kosalekeza kwaukadaulo wamakina otchinjiriza, kapangidwe ka ma motors kumafunikira kutulutsa kowonjezereka komanso kuchepetsedwa kwa voliyumu, kupangitsa mphamvu yotenthetsera ya ma motors atsopano kukhala ang'onoang'ono ndi ang'onoang'ono, komanso kuchulukirachulukira kumakhala kofooka komanso kofooka; ndipo chifukwa cha kuwongolera kwa makina opangira makina, ma mota amafunikira kuthamanga pafupipafupi m'njira zosiyanasiyana monga kuyambira pafupipafupi, kubowoleza, kuzungulira ndi kubweza, ndi katundu wosiyanasiyana, zomwe zimayika zofunikira zapamwamba pazida zodzitetezera. Kuphatikiza apo, ma mota ali ndi ntchito zambiri ndipo nthawi zambiri amagwira ntchito m'malo ovuta kwambiri, monga chinyezi, kutentha kwambiri, fumbi, zowononga, ndi zina zambiri. Kuphatikizana ndi zolakwika pakukonza magalimoto komanso zosiyidwa pakuwongolera zida. Zonsezi zapangitsa kuti ma injini amasiku ano awonongeke mosavuta kuposa kale.
- Chifukwa chiyani chitetezo cha zida zodzitetezera sichiri chabwino?
Zida zachikhalidwe zodzitetezera pamagalimoto nthawi zambiri zimakhala ma fuse ndi ma relay otenthetsera. Fuse ndiye zida zoyambirira komanso zosavuta zotetezera. M'malo mwake, ma fuse amagwiritsidwa ntchito makamaka kuteteza mizere yamagetsi ndikuchepetsa kufalikira kwa zolakwika pakachitika zolakwika zazifupi.
Ndizosagwirizana ndi sayansi kuganiza kuti fuseyi imatha kuteteza mota kuti isayende mozungulira kapena mochulukira, ndikusankha fuyusiyo molingana ndi zomwe zidavotera m'malo moyambira pamotoka. Komabe, ndizotheka kuwononga mota chifukwa cha kulephera kwa gawo.
Thermal relay ndiye chida chomwe chimagwiritsidwa ntchito kwambiri poteteza kuchuluka kwa magalimoto. Komabe, relay yotenthetsera imakhala ndi ntchito imodzi, kukhudzika kochepa, zolakwika zazikulu, ndi kusakhazikika bwino, zomwe zadziwika ndi ambiri ogwira ntchito zamagetsi. Zowonongeka zonsezi zimapangitsa chitetezo cha injini kukhala chosadalirika. Izi ndizochitikadi; ngakhale zida zambiri zili ndi matenthedwe otumizirana matenthedwe, chodabwitsa cha kuwonongeka kwagalimoto komwe kumakhudza kupanga kwanthawi zonse kumakhala kofala.
- Chitetezo chamoto chabwino?
Wotetezera wamagalimoto abwino si omwe ali ndi ntchito zambiri, kapena otchedwa apamwamba kwambiri, koma othandiza kwambiri. Ndiye nchiyani chomwe chiri chothandiza? Kuchita kuyenera kukumana ndi zinthu zodalirika, zachuma, zosavuta, ndi zina zotero, ndikukhala ndi chiŵerengero chapamwamba chamtengo wapatali. Ndiye chodalirika nchiyani?
Kudalirika kuyenera kuyamba kukumana ndi kudalirika kwa ntchitoyo, monga kuchulukirachulukira ndi kulephera kwa gawo kuyenera kugwira ntchito modalirika pakulephera mopitilira muyeso komanso kulephera kwa gawo muzochitika zosiyanasiyana, njira, ndi njira.
Kachiwiri, kudalirika kwa chitetezo chokha (popeza chotetezera ndicho kuteteza ena, chiyenera kukhala chodalirika kwambiri) chiyenera kukhala chokhazikika, chokhazikika komanso chokhazikika kumadera osiyanasiyana ovuta. Zachuma: khalani ndi mapangidwe apamwamba, mawonekedwe oyenera, akatswiri komanso kupanga kwakukulu, kuchepetsa mtengo wazinthu, ndikubweretsa phindu lalikulu kwambiri lazachuma kwa ogwiritsa ntchito. Kusavuta: Iyenera kukhala yofanana ndi mawotchi otenthetsera potengera kuyika, kugwiritsa ntchito, kusintha, mawaya, ndi zina zambiri, komanso kukhala kosavuta komanso kosavuta momwe mungathere. Ndichifukwa chake akatswiri oyenerera adaneneratu kwanthawi yayitali kuti kuti muchepetse zida zodzitchinjiriza zamagetsi zamagetsi, kapangidwe kopanda magetsi (passive) iyenera kupangidwa ndikukhazikitsidwa, ndipo ma semiconductors (monga thyristors) ayenera kugwiritsidwa ntchito m'malo mwa electromagnetic. actuators ndi kukhudzana. Mwa njira iyi, ndizotheka kupanga chipangizo chotetezera chomwe chili ndi zigawo zochepa kwambiri. Tikudziwa kuti kuchitapo kanthu kumabweretsa kusadalirika. Wina amafunikira mphamvu yogwirira ntchito kuti agwire bwino ntchito, ndipo winayo amataya mphamvu yogwira ntchito gawo likasweka. Ichi ndi chotsutsana chomwe sichingagonjetsedwe nkomwe.
