Nzira yekuyedza pombi yemafuta ine multimeter

Motokari yako haisi kutanga? Cheki injini chiedza chave nenguva yakadini?

Kana mhinduro yako kumibvunzo iyi iri hongu, ipapo pombi yako yemafuta inogona kunge iri dambudziko. 

Pombi yemafuta ndicho chikamu chemagetsi chiri mumotokari yako chinopa injini huwandu hwemafuta kubva mutangi remafuta kuti irambe ichishanda zvakanaka.

Kana zvisina kunaka, system yako yekupisa kana mota yese haisi kushanda.

Vanhu vazhinji havazive maitiro ekuyedza chikamu ichi uye isu tiripano kuti tibatsire.

Ngatitangei.

Chii chinoita kuti pombi yemafuta itande?

Tichifunga nezve mashandiro anoita pombi yemafuta, pane zvinhu zvitatu zvikuru zvinoita kuti itadze. Aya ndiwo mapfekero echisikigo, kusvibiswa uye kupisa.

Kupfeka uye kubvaruka kwakajairika kumapombi anga achimhanya kwemazana emakore uye akagadzirira kuchinjwa nekuda kwemagetsi asina simba.

Kusvibiswa kunokonzera kuwanda kwemarara netsvina kupinda mupombi yemafuta uye kuvhara sefa.

Izvi zvinodzivirira mudziyo kubva pakudhonzera mukati uye kuendesa mafuta akakwana kuinjini kana ichidiwa.

Kupisa zvakanyanya ndicho chikonzero chinowanzoitika chekutadza kwepombi yemafuta. 

Mazhinji emafuta anotorwa kubva mutangi yako anodzoserwa kwairi, uye mvura iyi inobatsira kutonhodza iyo yese pombi system. 

Paunogara uchidzikira mafuta mutangi, unorega iyi kutonhora uye pombi yako inotambura. 

Zvikamu zvaro zvemagetsi zvinokuvara nekufamba kwenguva, uye wobva watanga kuona zvimwe zviratidzo zvakaita sekutadza kushanda zvakanaka kweinjini, kupisa kweinjini, kusashanda zvakanaka kwemafuta, kumhanyisa kwakashata, kana kutadza kumhanyisa mota.

Zviratidzo izvi zvakafanana kana uine matambudziko kana uchida kutarisa chinja chako chekudzima kana PCM yako.

Saka, kuti uve nechokwadi chekuti pombi yako ndiyo ine mhosva, unoiongorora. 

Nekudaro, pane zvimwe zvikamu, senge pombi yemafuta relay, izvo zvakakodzera kutariswa usati wanyura mupombi pachayo ine multimeter.

Maitiro ekuyedza mafuta epombi relay ine multimeter

Iyo relay ndiyo chikamu chemagetsi chemagetsi ako chinopisa chinongopa simba pombi yehuni kana ichidikanwa.

Kutarisa relay inzira inonyengerera kuti utarise, asi inokuchengetedza kushushikana kwekutarisa pombi yemafuta kana dambudziko rawanikwa pano.

Iyo relay ine macontact mana; pini yepasi, pini yekupinza voltage, pini yekutakura (inoenda kune pombi yemafuta), uye pini yebhatiri.

Neiyi diagnostic, iwe unoda kutarisa kana relay iri kushanda nemazvo, ichiisa kunze huwandu hwakakodzera hwemagetsi. Aya mana ekubatika akakosha pabvunzo yedu.

1. Bvisa pombi yemafuta kubva pamotokari yako

Iyo relay inowanzo kuwanikwa mu distributor fuse box padhuze nebhatiri remota kana pa dashboard yemota. 

Inogona kunge iri kumwe kunhu mumotokari yako, saka unogona kutsvaga pawebhusaiti yenzvimbo chaiyo yemodhi yemotokari yako.

Kana wangoiwana, unongoisunungura kuti ufumure mapini mana.

2. Tora 12V Power Supply

Pabvunzo iyi, unozofanirwa kushandisa ekunze magetsi kupa 12 volts kune yako relay. Tinoda kutevedzera mamiriro ezvinhu kana ichiri yakabatana nemotokari. Bhatiri remotokari yako inzvimbo huru ye12V kushandisa.

3. Batanidza multimeter inotungamira kune bhatiri uye kutakura zviteshi

Iine multimeter yakaiswa kuDC voltage renji, batanidza iyo dzvuku bvunzo inotungamira kune bhatiri terminal uye dema bvunzo inotungamira kune yekuremedza terminal.

4. Isa simba kune pombi yemafuta relay

Iwe unozoda waya dzine alligator zvimedu kuti ubatanidze magetsi kune anotumirwa macontacts. Ngwarira pano.

Batanidza waya isina kunaka kubva kutsime kuenda kune yepasi terminal uye iyo yakanaka waya kune inopinza voltage terminal. 

5. Reta zvabuda

Kutanga, iwe unofanirwa kunzwa ruzha rwekudzvanya kubva kune relay pese paunoisa ikozvino kwairi.

Ichi chiratidzo chekuti chiri kushanda, asi mune zvimwe zviitiko iwe uchiri kuda kuita mamwe macheki ane multimeter.

Ukatarisa mita, kana usiri kuwana kuverenga kwakatenderedza 12V, iyo relay haina kunaka uye inoda kutsiviwa.

Kune rumwe rutivi, kana ukaona 12 volt kuverenga, relay yakanaka uye iwe unogona ikozvino kuenda kune pombi yemafuta pachayo.

Nzira yekuyedza pombi yemafuta ine multimeter

Batanidza iyo multimeter yakanaka inotungamira kune mhenyu yepombi yekubatanidza waya, batanidza iyo isina kunaka kumberi kwesimbi iri padyo, wobatidza moto usina kutanga injini. Iyo multimeter inofanira kuratidza anenge gumi nemaviri volts kana pombi yakanaka..

Iyi nzira inosanganisira zvakawanda, pamwe nezvimwe zvikamu zvekuyedza uchishandisa multimeter, uye isu tichaenda pamusoro pavo zvakadzama.

1. Tarisa fuse yepombi yemafuta

Sezvakaita nerelay, chimwe chikamu chaunogona kuongorora uye kukurerutsira kushushikana ndeye fuse.

Iyi 20 amp fuse iri mubhokisi rako rekusangana (nzvimbo inoenderana nemotokari yako).

Pombi yako yemafuta haishande kana ine fuse yakakanganisika, uye unogona kungoona kana fuse yako yakaipa kana yakatyoka kana kuti ine mucherechedzo wakatsva.

Neimwe nzira, multimeter inogonawo kuuya inobatsira.

Seta iyo multimeter kune yekupikisa maitiro, isa iyo multimeter probes pane yega yega fuse uye tarisa kuverenga.

Resistance mode inowanzotsanangurwa nechiratidzo "Ohm".

Kana iyo multimeter ichikuratidza "OL", iyo fuse yedunhu yakashata uye inoda kutsiviwa.

Kana iwe ukawana kukosha pakati pe 0 ne 0.5, fuse yakanaka uye unogona kuenda kune pombi yemafuta.

2. Isa iyo multimeter kune inogara voltage

Mota yako inomhanya paDC, saka iwe unoda kuseta multimeter yako kune DC voltage kuseta kuti bvunzo dzako dzive dzakaringana.

Kuenda kumberi, isu tichamhanyisa maviri voltage kudonhedza bvunzo pane akasiyana waya yekubatanidza papombi yako yemafuta.

Aya ndiwo mhenyu waya yekubatanidza uye yepasi waya yekubatanidza.

3. Shandura moto kune "On" nzvimbo.

Shandura kiyi yekudzima kune "On" chinzvimbo pasina kutanga injini.

Iwe unongoda kupa simba rako repombi waya kuti umhanye bvunzo dzayo.

4. Tarisa live connector 

Waya mhenyu ndicho chinongedzo chinobva kune relay. Zvinotarisirwa kunge zviri pamhepo yakafanana nebhatiri remotokari, saka ungangoda kubvunza bhuku rekushandisa usati waenderera nebvunzo iyi.

Pasinei neizvi, mabhatiri emotokari akawanda akaiswa pa12 volts, saka tinoshanda navo.

Iine multimeter yakabatana neDC voltage, ongorora waya yakanaka nepini uye ubatanidze iyo tsvuku yakanaka multimeter bvunzo inotungamira kwairi.

Iwe wobva wagaya yako dema negative probe kune chero simbi iri pedyo. 

Kana pombi yemafuta yakanaka, kana paine huwandu hwakakodzera hwemagetsi akaiswa kune mhenyu waya yekubatanidza, ungatarisira kuona kuverenga kwegumi nemaviri volts. 

Kana kukosha kwadonha nekupfuura 0.5V, pombi yemafuta yatadza kudonha bvunzo uye inoda kutsiviwa.

5. Tarisa pasi waya yekubatanidza

Waya yepasi ndicho chinongedzo chinoenda chakananga kune chassis yemotokari yako.

Iwe unoda kuiyedza kuti uone kuti yakanyatsodzika pasi uye kuti hapana dunhu rakavhurika kana kukanganisa mupombi yemafuta.

Mushure mekuisa pasi dema bvunzo inotungamira kune simbi pamusoro, batanidza yekumashure bvunzo inotungamira kune pasi waya uye batanidza iyo dzvuku bvunzo lead kune yekumashure bvunzo lead. 

Iwe unotarisirwa kuwana kukosha kweanenge 0.1 volts kubva kune yako multimeter.

Chero kukosha kuri pamusoro pe 0.5V kunoreva kuti pombi yemafuta haina kunyatsodzika pasi uye iwe unofanirwa kutarisa waya kuti kukuvara.

Tsiva kana insulate waya yekubatanidza kana ukavawana.

mhedziso

Chete kana iwe ukatarisisa kune zvakadzama unogona kuyedza nyore pombi yako yemafuta. Zvakafanana nekuongororwa kwezvimwe zvikamu zvemagetsi.

Inowanzobvunzwa Mibvunzo

Pombi yemafuta inofanira kuenderera mberi here?

Pombi yehutsi ine hutano inotarisirwa kuve nekuenderera mberi pakati peyakanaka (mhenyu) uye isina kunaka (pasi) waya. Uchishandisa iyo multimeter mukupikisa (ohm) modhi, unogona kutarisa zviri nyore mwero wekupokana kana kuvhurika redunhu mudunhu.

Chii chingaita kuti pombi yemafuta isawane simba?

Fuse yakakuvadzwa inodzivirira pombi yako yemafuta kubva pakushanda. Kana pombi relay yakakuvadzwa zvakare, pombi yako yemafuta haisi kuwana simba rainoda kuti rifambe nemazvo.
