Chii chinoita relay mumotokari?

I. Nhanganyaya

Automotive relaychinhu chakakosha chemagetsi emotokari.Vanoita semachinja anodzora kuyerera kwesimba remagetsi kunzvimbo dzakasiyana dzemotokari, semwenje, mhepo inofefetera, uye nyanga.Mota relay ine basa rekudzora mazinga emagetsi, kutungamira magetsi emagetsi, uye kuita logic mabasa anoita kuti mota ifambe zvakanaka.Muchinyorwa chino, isu tinopa tarisiro yezvinoitwa relay mumotokari, marudzi akasiyana erelay, uye maitiro ekuongorora zvakajairika nyaya nemotokari relay mumotokari.Pakupera kwechinyorwa chino, iwe uchave nekunzwisisa kuri nani kwekukosha kwemotokari relay mumotokari yemagetsi system.

II.Chii chinoita relay mumotokari?

Relays inoita basa rakakosha mumotokari yemagetsi system, kunyanya kana zvasvika pakudzora makwikwi ekuyerera anoyerera.Vanoita semagetsi emagetsi, vachibvumira matunhu akaderera emazuva ano kuti adzore masheji ekuyerera kwepamusoro kuitira kuti ape simba zvikamu zvakasiyana zvemotokari.Semuenzaniso, kana iwe ukabatidza mwenje wako wemwenje, dunhu rakaderera rinopa simba relay coil, iyo inogadzira iyo magnetic field inovhara relay contacts, ichibvumira simba remagetsi kuti riyerere kune malights.

Kusiyana nekuchinja, relays inobvumira kutonga kwemaseketi akawanda ane switch imwechete kana control module.Relays inogona kunge yakavhurika (NO) kana inowanzovharwa (NC), uye inogona kushandiswa kune dzakasiyana siyana dzekushandisa, sekudzora nyanga yemotokari.

Relays inoshanda nekushandisa dhizaini yekudzora kugadzira iyo magineti inodhonza kana kusundira seti yevanodzosera macontacts.Kana yazvino ichiyerera, inodhonza macontacts pamwe chete, ichibvumira simba remagetsi kuyerera.Kana iyo coil iine de-energized, iyo magineti inodonha, ichibvumira vanobatika kuti vaparadzane uye kutyora kubatana kwemagetsi.

Pakazere, relays inhengo dzakakosha mumotokari yemagetsi system, inobvumira kutonga kwemaseketi akawanda ane switch imwechete kana control module.

III.Mhando dzemotokari relays

Kune akati wandei emhando dzemotokari relay dzinowanzo shandiswa mumotokari.Heano mamwe emhando dzakajairika dzerelay uye mabasa awo:

Kazhinji vhura relay (NO): Iyi mhando yerelay yakavhurika kana coil isina simba, uye inovharwa kana coil yasimbiswa.Inowanzo shandiswa kudzora maseketi ekuyerera akakwira, senge maraiti emotokari kana nyanga.

Kazhinji yakavharwa relay (NC): Iyi mhando yerelay inovharwa kana coil isina simba, uye inovhurwa kana coil yasimbiswa.Iyo inowanzoshandiswa pakudzora yakaderera ikozvino inoyerera masekete, seaya anowanikwa ari kure switch kana in-line switch.

Changeover relay: Iyi mhando yerelay ine maviri seti yevanobatika uye inogona kushandiswa kushandura pakati pemaseketi maviri, kusanganisira anowanzo kuvhurika relay uye anowanzo kuvharwa relay.Inowanzo shandiswa kudzora mhepo yemota kana ma fan motors.

Single Pole Double Kanda (SPDT) relay: Iyi mhando yerelay ine imwechete yakavhurika yekubata uye imwe inowanzovharika kubata.Inowanzo shandiswa kudzora mafambiro emagetsi muDC masisitimu, seaya anowanikwa mumamota anoputika.

Micro relay: Iyi mhando yerelay idiki relay iyo inowanzoshandiswa mumahwindo otomatiki kana marambi ebetsero.

Imwe neimwe mhando yerelay inoshanda zvakasiyana uye inoshandiswa kune akasiyana maapplication mumotokari.Kunzwisisa mhando dzakasiyana dzemareyi uye mabasa awo anogona kubatsira kuongorora nyaya nemagetsi emotokari system.

IV.Nyaya dzakajairika nemotokari relays

Kufanana nechero chinhu chemagetsi, mareyi emotokari anogona kutadza kana kusangana nematambudziko.Heano mamwe matambudziko akajairika ane mota relays:

Relay kutadza: Nekufamba kwenguva, vanobatika mubreak relay vanogona kupera kana kukuvara, zvichikonzera kukundikana.Iyo yakaipa relay inogona kukonzera nyaya dzakasiyana-siyana, senge isiri-inoshanda sedunhu, kushanda kwepakati, kana kukuvadza kune zvimwe zvikamu mumagetsi emotokari.

Voltage spikes: Kana relay yakadzimwa, iyo magineti inodonha uye inogona kugadzira voltage spike mudunhu.Iyi voltage spike inogona kukuvadza zvimwe zvikamu mudunhu, senge control module kana relay coil pachayo.

Saka, chii chinoitika kana relay yakashata?Zviratidzo zvinogona kusiyana zvichienderana nedunhu chairo uye mashandisirwo, asi zvimwe zvinozivikanwa zviratidzo zveakaipa relay zvinosanganisira:

Isiri-inoshanda sedunhu: Kana relay yemota ikatadza, dunhu rarinotonga rinogona kumira kushanda zvachose.

Kushanda kwepakati: Iyo yakaipa relay inogona kuita kuti dunhu rishande zvishoma nezvishoma kana chete pasi pemamwe mamiriro.

Kudzvanya ruzha: Kana relay yapihwa simba, inofanirwa kuburitsa inonzwika yekudzvanya ruzha.Kana relay iri kutadza, inogona kuburitsa ruzha rwekudzvanya ruchienderera kana kusatombodaro.gadzira an

Akatsva kana akanyungudutswa mabikirwo: Muzviitiko zvakanyanyisa, kudzoreredzwa kwakashata kunogona kuita kuti mabatiro apise kana kunyungudika, zvichikonzera kukuvara kune zvimwe zvikamu mudunhu.

Kugaro gadzirisa uye kuongororwa kwerelays kunogona kubatsira kudzivirira nyaya nekudzibata nekukurumidza.

V. Nzira yekuongorora sei relay yakaipa mumotokari

Kana iwe uchifungidzira kuti relay mumotokari yako yakaipa, pane matanho mashoma aungatora kuti uongorore nyaya yacho:

Teerera pakudzvanya:

Paunobatidza chikamu chinodzorwa nerelay, senge maraiti emusoro kana air conditioning, teerera kune ruzha rwekudzvanya runobva pabreak relay.Ruzha urwu runoratidza kuti relay iri kupihwa simba uye inofanirwa kunge ichishanda nemazvo.

Tarisa fuse:

Usati waedza relay pachayo, tarisa fuse yedunhu rainotonga.Fuse inoputika inogona kukonzera zviratidzo zvakafanana kune yakaipa relay.

Chinjana neinozivikanwa relay yakanaka: 

Kana iwe uine imwe relay mumotokari yako yaunoziva kuti iri kushanda nemazvo, chinjanisa neanofungidzira relay.Kana chikamu chacho chikatanga kushanda nemazvo, unenge waona iyo yakanganisa relay.

Edza ne multimeter:

Kana uine multimeter, unogona kuedza relay zvakananga.Seta iyo multimeter kune iyo ohms kugadzika uye bata maprobe kune ekutumira mameta.Iwe unofanirwa kuona kuverenga kwe zero ohms kana relay yakasimbiswa uye kusingaperi kuramba kana zvisiri.

Nekutevera nhanho idzi, unogona kuongorora yakashata relay mumotokari yako uye kutora matanho ekuitsiva kana kutenga imwechete relay isati yakonzera kumwe kukuvadza.

VI.Chii chinoita kuti relay ikunde?

Relays dzakagadzirirwa kuti dzigare uye dzigare kwenguva refu, asi dzinogona kutadza nekufamba kwenguva.Hezvino zvimwe zvezvikonzero zvinowanzoitika zvekutadza kwerelay:

Zera:

Kufanana nezvakawanda zvemagetsi uye zvemagetsi zvikamu, akawanda relay anozopedzisira apera nekufamba kwenguva.Iyo yakawanda relay inoshandiswa, zvakanyanya mukana wekukundikana.

Kuratidzwa kune tembiricha yepamusoro:

Zvifambiso zvemotokari zvinowanzowanikwa mukamuri yeinjini, kwaanogona kuratidzwa kune tembiricha yakakwira.Nokufamba kwenguva, kupisa uku kunogona kuita kuti zvikamu zverelay zviputse uye zvikundikane.

Voltage spikes:

Voltage spikes, iyo inogona kuitika kana relay ikabatidzwa kana kudzimwa, inogona kukuvadza mabatiro eiyo relay uye kuita kuti itadze.

Overloading:

Kana relay inoshandiswa kudzora dunhu rinokwevera zvakawandisa ikozvino, rinogona kupisa nekutadza.

Kuisa zvisina kunaka:

Kana relay isina kuiswa zvakanaka, inogona kukuvara kana kutadza kushanda nemazvo.

Kuti udzivise kutadza kwerelay, zvakakosha kutevedzera aya matipi:

Shandisamareyi emhando yepamusoro:

Kusarudza relay yemhando yepamusoro kunogona kubatsira kuve nechokwadi kuti inogara kwenguva refu uye inoshanda nemazvo.

Chengetedza relay zvakanaka: 

Pese pazvinogoneka, ma mount relays munzvimbo umo anozosangana nekupisa kushoma.

Shandisa marelay akakodzera edunhu:

Ita shuwa yekusarudza relay ine yakakwira yakakwana ikozvino chiyero chekubata dunhu richange richidzora.

Tevera nzira dzekuisa dzakakodzera: 

Iva nechokwadi chekutevera mirairo yemugadziri paunenge uchiisa relay kuti urege kuikuvadza.

Nekutevera matipi aya, unogona kubatsira kudzivirira kutadza kwerelay uye kuona kuti mota yemagetsi system yako inoshanda nemazvo kwemakore anotevera.

VII.Mhedziso

Mukupedzisa, kutenderera kwemotokari kunoita basa rakakosha mumotokari.Ivo vanoshanda sema switch anodzora mazinga emagetsi uye anoshanda akasiyana siyana emotokari, senge maraiti emusoro, blower motors, uye air conditioning.

Takakurukura nezvemhando dzakasiyana dzemotokari relays, kusanganisira dzinowanzo kuvhurika relay, dzinowanzovharwa relays, shanduko yekuchinja, uye micro relays.Isu takaratidzawo nyaya dzakajairika dzinogona kumuka nerelays, senge voltage spikes uye kutadza, uye takapa matipi ekuongorora nekudzivirira nyaya idzi.

Kuti udzidze zvakawanda nezve mareyi emotokari, vaverengi vanogona kutarisa kune zviwanikwa zvakaita semugadziri wedatabase kana kubvunza neanovimbika nyanzvi yemotokari.Izvo zvakakosha kuve nekunzwisisa kwekutanga kwemotokari relays kuti uve nechokwadi chekuchengetedza uye kuvimbika kwemagetsi emotokari yako.
