Nzira yekutarisa injini ne multimeter? (3 nzira yekufambisa)

Motokari yakaipa inogona kukonzera matambudziko mazhinji. Nenzira iyi hauzive paungangoda kutarisa injini yako. Ndicho chikonzero nhasi tichaona sei kutarisa injini ine multimeter. Nekudaro, kune iyi maitiro, iwe unozoda humwe hunyanzvi hweDIY. Nehumwe hunyanzvi hweDIY uye kuita kwakaringana, unogona kupedza basa zviri nyore.

Muzhinji, kuti uedze mota, iwe unofanirwa kutanga waisa iyo multimeter mukupikisa maitiro. Wobva watarisa materminals emota uye waya. Chinangwa ndechekuedza ma windings emhepo yakazaruka kana pfupi.

Mukuwedzera kune nzira inotsanangurwa pamusoro apa, kune dzimwe nzira mbiri dzatinogona kuedza nayo motokari yemagetsi. Pano tichakurukura ese matatu mota bvunzo. Saka ngatitangei.

Muedzo 1: Enzanisa voltage kuyambuka capacitor terminals neiyo inoshandiswa voltage

Kana yakanyatsobatanidzwa, voltage pa capacitor terminal inofanira kuva 1.7 nguva yemagetsi emagetsi. Kana iwe uri kuwana kuverenga zvinoenderana nereshiyo yataurwa pamusoro, zvinoreva kuti mota iri kuwana iyo voltage chaiyo. Kune iyi mota bvunzo, isu tichashandisa maviri multimeters; Circuit tester A uye muyedzi wedunhu B.

Danho 1: Tarisa magetsi ekupa magetsi ane dunhu retesta A.

Sezviri mudhayagiramu iri pamusoro, tanga wabatanidza iyo dzvuku bvunzo inotungamira kune tsvuku waya; batanidza probe nhema kune nhema waya. Iyi ndiyo nzira yedunhu tester A. Iyo multimeter inofanira kunge iri mu AC voltage mode. Usati wabatanidza iyo multimeter kune mota, iwe unofanirwa kugadzira iyo inodiwa marongero eiyo multimeter. Kana iwe ukatevera nhanho idzi nenzira kwayo, saka iwe unofanirwa kuwana voltage yemagetsi ekupa. Kana iwe uri kushandisa 100V AC mota, iwe unowana 100V pane multimeter.

Danho rechipiri: Tarisa voltage pa capacitor terminals uchishandisa wedunhu tester B.

Zvino shandisa Circuit Tester B kutarisa voltage pane capacitor terminals. Batanidza probe tsvuku kune tsvuku tsvuku. Wozobatanidza probe nhema kune waya chena. Zvino tarisa voltage ne multimeter. Kana zvese zvinongedzo zvakanaka, iwe uchawana kuverenga kwe 1.7 nguva yekuverenga magetsi.

Semuenzaniso, kana uri kushandisa 100V mota yebvunzo iyi, iyo multimeter ichaverenga 170V.

Kana iwe ukawana kuverenga kwe1.7 nguva yesimba rekupa simba, zvinoreva kuti mota iri kushanda zvakajairika. Nekudaro, kana usiri kuwana kuverenga uku, dambudziko rinogona kunge riri neinjini yako.

Muedzo 2: tarisa magetsi anotakurwa kuburikidza netambo

Chero chero mhando yewaya dzakakanganisika kana zvibatanidza zvinogona kuva chikonzero cheiyo injini kusashanda zvakanaka. Naizvozvo, zvinogara zvakanaka kuti utarise waya nekubatanidza usati watora chero mhedzisiro. Neiyi nzira, isu ticha tarisa kana mota yedunhu yakavhurika kana ipfupi ine nyore kuenderera bvunzo.

Danho 1 - Dzima simba

Kutanga, dzima simba. Simba haridiwi kana uchiita bvunzo yekuenderera mberi.

Nhanho 2 - Gadzira zvinongedzo zvinoenderana nedhayagiramu

Tarisa dhayagiramu iri pamusoro uye batanidza C uye D wedunhu tester zvakateerana. Kuti uite izvi, unofanirwa kubatanidza mutsara mutsvuku C kune tambo yakasviba uye mutsvuku unotungamira D kune tambo tsvuku. Ikozvino batanidza maviri asara maprobes matema C uye D kusvika kumagumo etambo yekuwedzera. Kana paine mabreak padunhu pasi pekuyedzwa, mamultimeters anotanga beeping.

Cherechedza: Paunenge uchitarisa waya, nguva dzose sarudza nzvimbo yakazaruka pedyo nejini. Kana uchibatanidza masensa kune waya, ita shuwa kuti akabatana nemazvo.

Muedzo 3: Motor winding resistance test

Muyedzo iyi, tiri kuenda kuyera mota inomonereka kuramba. Tichazozvienzanisa neyekutanga yakaverengerwa mota inotenderera tsika. Mushure meizvi, tinogona kutarisa mamiriro ejini nemaitiro maviri.

Danho 1 - Bvisa zvose zvingasarudzwa

Kutanga, bvisa zvimwe zvikamu kubva kudunhu remota, senge capacitors uye tambo dzekuwedzera.

Nhanho 2 - Seta yako multimeter

Zvino isa ma multimeters ako kune kuramba maitiro. Kana iwe uchiyeuka, mune mbiri yapfuura bvunzo, isu tinoisa iyo multimeter kune voltage mode. Asi kwete pano.

Nhanho 3 - Batanidza masensa

Batanidza ese matema bvunzo anotungamira kune nhema waya. Ikozvino batanidza muto mutsvuku wedunhu tester E kune waya tsvuku. Wobva wabatanidza iyo dzvuku lead yeF circuit tester kune chena waya. Kana iwe uchiri kuvhiringidzika, dzidza mufananidzo wakaratidzwa pamusoro apa. (1)

Nhanho 4 - Tarisa uye Enzanisa Kuverenga

Kuverenga kwe-multimeter kunofanira kuva 170 ohms, zvichipiwa kuti kana tikashandisa motokari yevolti 100. Dzimwe nguva kuverenga uku kunogona kuva pasi pe 170 ohms, somuenzaniso, nechepakati pfupi mukati, kuverenga kunogona kuva pasi pe170 ohms. Zvisinei, kana ma windings akakuvadzwa, kuverenga kunofanira kudarika zviuru zvishoma ohms.

Mumuenzaniso wepamusoro, takashandisa mota ye100V. Asi kana zvasvika kune mamwe mota, iwe uchafanirwa kuziva akaverengerwa kukosha zvichienderana nemuenzaniso. Edza kutsvaga pamhepo kana kubvunza mugadziri. Zvadaro enzanisa maitiro maviri. (2)

Chii chandinofanira kuita kana injini ikakundikana miedzo iri pamusoro?

Kana injini yako ikatadza bvunzo idzi, saka chimwe chinhu chakashata nayo. Chikonzero cheiyi nyaya chinogona kunge chiri mota yakaipa kana zvikanganiso senge; yakaipa relay, switch, tambo kana voltage isiriyo. Chero chikonzero, une mota yakashata.

Nekudaro, zvichienderana nebvunzo imwe neimwe, mhinduro dzinogona kusiyana. Semuenzaniso, kana mota ikatadza bvunzo yekutanga, dambudziko riri mu wiring kana capacitors. Kune rimwe divi, kana mota ikatadza bvunzo yechipiri, dambudziko riri mukubatanidza kana tambo. Kuti uwane kunzwisisa kwakanaka, heino gwara rakapfava.

Kana injini ikakundikana Test 1Iwe ungangoda kutsiva iyo wiring uye capacitors.

Kana injini ikakundikana Test 2ungangoda kutsiva chinongedzo netambo.

Kana injini ikakundikana Test 03ungangoda kutsiva mota.

Matambudziko eMechanical akadai sekutadza bhora kutakura anogona kukanganisa injini yako. Iyi mamiriro anoitika nekuda kwekunyanyisa axial kana radial mutoro. Iwe unogona zvakare kutarisa kune marudzi aya ematambudziko. Saka, tevera matanho aya.

1 Step: Kutanga, bvisa gearbox uye mota.

2 Step: Zvadaro shandura shaft newachi uye nekutarisana newachi.

3 Step: Kana iwe ukanzwa kukweshera kusina kujairika kana ruzha apo shaft inotenderera, ichi chiratidzo chekusarongeka kana kukuvadzwa. Muchiitiko ichi, ungada kutsiva injini.

Summing up

Idzi nzira nhatu ndidzo mhinduro dzakanakisa dzekuyedza mota dzemagetsi. Kana iwe ukatevera matanho aya nemazvo, unogona kuona mamiriro einjini chero ipi zvayo. Nekudaro, kana uchine kupokana kupi zvako, inzwa wakasununguka kudzokorora chinyorwa zvakare. 

Tarisa zvimwe zvezvinyorwa zvedu pazasi.

• Maitiro ekuyedza fan fan ine multimeter
• Maitiro ekuverenga analog multimeter
• Kutarisisa kweiyo Power Probe multimeter
