Momwe mungayang'anire injini ndi multimeter? (3 njira zowongolera)

Galimoto yoyipa imatha kuyambitsa mavuto ambiri. Mwanjira iyi simudzadziwa nthawi yomwe mungafunikire kuyang'ana injini yanu. Ndicho chifukwa chake lero tiwona momwe tingayang'anire injini ndi multimeter. Komabe, pakuchita izi, mudzafunika maluso ena a DIY. Ndi luso lina la DIY komanso kuchita bwino, mutha kumaliza ntchitoyi mosavuta.

Nthawi zambiri, kuyesa injini, choyamba muyenera kuyika multimeter mumayendedwe okana. Kenako yang'anani ma terminals a mota ndi mawaya. Cholinga chake ndikuyesa ma windings kuti akhale otseguka kapena ozungulira.

Kuphatikiza pa njira yomwe tafotokozera pamwambapa, pali njira zina ziwiri zomwe tingayesere galimoto yamagetsi. Apa tikambirana mayeso onse atatu agalimoto. Choncho tiyeni tiyambe.

Mayeso 1: Fananizani ma voltage pa ma capacitor terminals ndi magetsi omwe amagwiritsidwa ntchito

Mukalumikizidwa bwino, voteji pa capacitor terminal iyenera kukhala 1.7 kuchulukitsa mphamvu yamagetsi. Ngati mukuwerenga molingana ndi chiŵerengero chomwe chatchulidwa pamwambapa, zikutanthauza kuti galimoto ikupeza mphamvu yoyenera. Pakuyesa kwa injini iyi, tigwiritsa ntchito ma multimeter awiri; Circuit tester A ndi circuit tester B.

Khwerero 1: Yang'anani voteji yamagetsi ndi choyesa dera A.

Monga momwe zilili pamwambapa, choyamba gwirizanitsani chiyeso chofiira ku waya wofiira; gwirizanitsani kafukufuku wakuda ku waya wakuda. Iyi ndi njira ya woyesa dera A. Multimeter iyenera kukhala mu AC voltage mode. Musanalumikizane ndi multimeter ku mota, muyenera kupanga zoikamo zofunika pa multimeter. Ngati mutsatira izi molondola, ndiye kuti muyenera kupeza voteji ya magetsi. Ngati mukugwiritsa ntchito mota ya 100V AC, mupeza 100V pa multimeter.

Khwerero 2: Yang'anani mphamvu yamagetsi pa capacitor terminals pogwiritsa ntchito circuit tester B.

Tsopano gwiritsani ntchito Circuit Tester B kuti muwone mphamvu yamagetsi kudutsa ma capacitor terminals. Lumikizani kafukufuku wofiyira ku waya wofiira. Kenako gwirizanitsani kafukufuku wakuda ku waya woyera. Tsopano yang'anani voteji ndi multimeter. Ngati malumikizidwe onse ali abwino, mupeza kuwerengera nthawi 1.7 kuchuluka kwa magetsi.

Mwachitsanzo, ngati mukugwiritsa ntchito 100V mota pamayeso awa, ma multimeter amawerenga 170V.

Mukawerenga ka 1.7 kuchuluka kwa magetsi, zikutanthauza kuti mota ikuyenda bwino. Komabe, ngati simukuwerenga izi, vuto likhoza kukhala ndi injini yanu.

Mayeso 2: yang'anani magetsi omwe amatengedwa kudzera pa chingwe

Mtundu uliwonse wa mawaya olakwika kapena zolumikizira zitha kukhala chifukwa cha kuwonongeka kwa injini. Choncho, nthawi zonse ndi bwino kuyang'ana mawaya ndi maulumikizidwe musanayambe kuganiza. Ndi njira iyi, tiwona ngati dera lagalimoto ndi lotseguka kapena lalifupi ndi mayeso osavuta opitilira.

Gawo 1 - Zimitsani mphamvu

Choyamba, zimitsani mphamvu. Mphamvu sizifunikira pochita mayeso opitilira.

Khwerero 2 - Pangani maulumikizidwe molingana ndi chithunzi

Yang'anani chithunzi pamwambapa ndikulumikiza choyesa dera la C ndi D motsatana. Kuti muchite izi, muyenera kulumikiza chotsogolera chofiira C ku waya wakuda ndi kutsogolera kofiira D ku waya wofiira. Tsopano gwirizanitsani zotsalira ziwiri zakuda zakuda C ndi D kumapeto kwa chingwe chowonjezera. Ngati pali zopumira padera poyesedwa, ma multimeter ayamba kulira.

Taonani: Mukamayang'ana mawaya, nthawi zonse sankhani malo otseguka pafupi ndi injini. Mukalumikiza masensa ku mawaya, onetsetsani kuti alumikizidwa bwino.

Mayeso 3: Kuyesa kukana kwa injini

Mu mayeso awa, tiyesa kukana kwa ma motor winding. Kenako tidzafanizira ndi zomwe zidawerengedwa poyambira ma motor winding. Pambuyo pake, tikhoza kuyang'ana mkhalidwe wa injini ndi mfundo ziwiri.

Khwerero 1 - Chotsani zigawo zonse zomwe mungasankhe

Choyamba, chotsani zowonjezera zowonjezera pamagetsi oyendetsa galimoto, monga ma capacitors ndi zingwe zowonjezera.

Khwerero 2 - Konzani ma multimeter anu

Tsopano ikani ma multimeter anu kuti akhale otsutsa. Ngati mukukumbukira, m'mayesero awiri apitawa, timayika ma multimeters kukhala ma voltage mode. Koma osati pano.

Gawo 3 - Lumikizani masensa

Lumikizani mayeso onse akuda kupita ku waya wakuda. Tsopano gwirizanitsani mzere wofiira wa circuit tester E ku waya wofiira. Kenako gwirizanitsani chingwe chofiira cha F circuit tester ku waya woyera. Ngati mudakali osokonezeka, phunzirani chithunzi chomwe chili pamwambapa. (1)

Khwerero 4 - Yang'anani ndi Kufananiza Zowerenga

Kuwerenga kwa ma multimeter kuyenera kukhala 170 ohms, kupatsidwa kuti ngati tigwiritsa ntchito injini ya volt 100. Nthawi zina zowerengerazi zimatha kukhala zosakwana 170 ohms, mwachitsanzo, ndi dera lalifupi lamkati, zowerengera zimatha kukhala zosakwana 170 ohms. Komabe, ngati ma windings awonongeka, kuwerenga kuyenera kukhala oposa zikwi zingapo ohms.

Muchitsanzo pamwambapa, tidagwiritsa ntchito mota ya 100V. Koma zikafika pama motors ena, muyenera kudziwa zomwe zidawerengedwa kutengera mtunduwo. Yesani kufufuza pa intaneti kapena funsani wopanga. Kenako yerekezerani mfundo ziwirizo. (2)

Kodi nditani ngati injini yalephera mayeso pamwambapa?

Ngati injini yanu ilephera mayesowa, ndiye kuti pali cholakwika ndi izo. Chifukwa cha nkhaniyi chikhoza kukhala choyipa cha injini kapena zida zolakwika monga; ma relay oyipa, masiwichi, zingwe kapena magetsi olakwika. Ziribe chifukwa chake, muli ndi injini yolakwika.

Komabe, kutengera mayeso aliwonse, mayankho amatha kusiyana. Mwachitsanzo, ngati galimoto ikulephera kuyesa 1, vuto liri mu wiring kapena capacitors. Komano, ngati galimoto ikulephera mayeso a 2, vuto liri mu cholumikizira kapena chingwe. Kuti mumvetsetse bwino, nayi kalozera wosavuta.

Ngati injini ikulephera kuyesa 1Mutha kusintha ma wiring ndi ma capacitors.

Ngati injini ikulephera kuyesa 2mungafunike kusintha cholumikizira ndi chingwe.

Ngati injini ikulephera kuyesa 03mungafunike kusintha motere.

Mavuto amakina monga kulephera kwa mpira kumatha kusokoneza injini yanu. Izi zimachitika chifukwa cha kuchuluka kwa axial kapena ma radial. Mwinanso mungafunike kufufuza za mitundu iyi. Choncho, tsatirani izi.

Chinthu cha 1: Choyamba, chotsani gearbox ndi mota.

Chinthu cha 2: Kenako tembenuzirani kutsinde mozungulira koloko.

Chinthu cha 3: Ngati mukumva kugwedezeka kwachilendo kapena phokoso pamene shaft ikuzungulira, ichi ndi chizindikiro cha kusalolera kapena kuwonongeka. Pankhaniyi, mungafunike kusintha injini.

Kufotokozera mwachidule

Njira zitatuzi ndi njira zabwino zoyesera ma mota amagetsi. Mukatsatira izi molondola, mutha kudziwa momwe injini iliyonse ilili. Komabe, ngati mukukayikirabe, khalani omasuka kubwerezanso nkhaniyo. 

Onani zina mwazolemba zathu pansipa.

• Momwe mungayesere injini ya fan ndi multimeter
• Momwe mungawerenge multimeter ya analogi
• Chidule cha Power Probe multimeter
