Maitiro ekugadzirisa air conditioning muBMW

Varidzi veBMW, kunyanya E39 uye E53 modhi, vanogona kazhinji kunzwa zvichemo zvekuti injini inotanga kupisa kana air conditioner ichimhanya, kunyanya pamhepo tembiricha uye kubatikana mumigwagwa. Zvikonzero zvekuputsika, zvichiita kuti kuwedzere kugadziriswa kwemhepo yemhepo muBMW, inogona kunge yakasiyana.

Zvikonzero zvekuputsika kweBMW air conditioner

Kusashanda kwakanyanya ndiko kukundikana kwemhepo inogadzirisa feni. Uku ndiko kukanganisa kwakakomba muchiitiko chekuti air conditioner haigone kushanda zvakajairika. Ehe, pane mukana wekutyaira neasina-kushanda mudziyo, asi hapana anovimbisa kuti haufanirwe kugadzirisa iyo air conditioner, kana iyo yese injini system.

Kuzvigadzirisa kwekuputsika kwakadaro haisi iyo yakanakisa sarudzo, kunyanya pamotokari dzakagadziriswa. Asi pakati pevanoda motokari dzeGermany kune mhizha vane ruzivo rwekugadzirisa chigadzirwa chakadaro mumamiriro egaraji.

Chekutanga, kana uchishanda muRussia, mota air conditioners inokundikana nekuda kwekushanduka kwekushisa kamwe kamwe. Chishandiso hachimirire mitoro yakawedzera pazasi-zero tembiricha kusvika -40 madhigirii, uye tembiricha imwechete ine chiratidzo chekuwedzera muzhizha.

Muzviitiko zvakawanda, zvinotora makore 3-4 kuti mamodheru akasakara apfeke zvachose fan fan. Kana kukanganisa kwakadaro kwakaitika pamotokari itsva, saka iyi ndiyo muchato.

Kukuvadza kwerudzii kunogona kuitika?

Usati waenderera mberi nekugadzirisa, unofanirwa kusarudza kuti chii chaicho chinokanganisa chingave. Inogona kuva:

•       fan output stage;
•       fan relay;
•       fan motor;
•       tsime resimba;
•       control voltage output.

Miedzo yesimba

Chokutanga pane zvose, unofanira kutarisa kushanda kweinjini pachayo. Kuti uite izvi, inopihwa nevoltage ye12V, ine waya yebhuruu uye brown inobatanidza bhodhi uye mota. Waya yechitatu inodiwa kudzora minus yerelay.

Kana zvose zvichishanda, mutyairi ane rombo rakanaka - anongoda kuwana uye kutsiva zvimwe zvikamu. Kana mota ikasatendeuka, uchafanira kutenga imwe itsva, inoda mari yakawanda.

Kana iwe uine zvinodiwa zvemotokari zvinodiwa, kugadzirisa kunotora anenge maawa maviri. Nyanzvi dzine ruzivo dzinokupa zano kuti utange wabvunza ane ruzivo rwemagetsi emotokari, nekuda kwekudzikira kwemhando yezvikamu zvinogadzirwa pasi perezinesi kubva kuBMW.

BMW Compressor Kugadzirisa

Iyo air conditioning system mumotokari dzeBMW inokonzeresa nhanho yekunyaradza kumutyairi nevafambi. Kuvonga chete kuvapo kwavo, vanogona kunzwa zvakanaka mumotokari mumamiriro okunze anopisa. Imwe yemidziyo mikuru yeiyi system ndeye compressor, ine basa nderekuona kutenderera kwefiriji muhurongwa. Tinogona kutaura zvakachengeteka kuti pasina kuvapo kwe compressor, kushanda kwehurongwa kunenge kusingabviri.

Kushanda kwegadziriro iyi kuri nyore kwazvo. Nerubatsiro rweBMW compressor, freon inopinzwa muradiator, uko gasi rinotonhodzwa uye rinoshandurwa kuita mvura nekuita kwefani. Kana pasina gasi rakakwana kana paine yakawandisa, izvi zvinogadzira mamwe mitoro paBMW compressor, nekukasira kupfeka kwezvinhu zvayo.

Mukuona kweizvi, kugadzirisa nguva dzose kwakakosha zvikuru, umo kutariswa kunofanirawo kubhadharwa kune mhepo yekupisa yemotokari dzeBMW.

Zviratidzo zvikuru zvecompressor malfunction

Matambudziko anonyanyozivikanwa eair conditioning system ndeaya:

•       Kusakwana kwemhepo inotonhora muimba uye kuonekwa kwemvura inoyerera, iyo chiratidzo chekuora mwoyo kwehurongwa;
•       Kuonekwa kwemanzwi ekunze, zvichiratidza kupera kwemavharuvhu uye pistons ye compressor.

Kana isu tichitaura nezve kugadziridzwa kweBMW compressor, kutanga kune zvese, uku ndiko kuongororwa kwezvinhu zvayo zvekushanda kubva pahunyanzvi hwekuona. Chekutanga, iyo freon level inotariswa nediagnostics yemuchina.

Mune ramangwana, compressor inoparadzaniswa uye inoparadzaniswa, kunaka uye kushanda kwechimwe nechimwe chezvinhu zvayo zvinoongororwa. Kugadziriswa kwakanyanya kweBMW mota compressor ndiko kudikanwa kwekutsiva inotakura, solenoid valve, pressure plate kana piston boka.

Kune rimwe divi, zvinofanirwa kucherechedzwa kuti kugadzirisa BMW compressor kunodhura zvishoma pane kutenga imwe nyowani. Iyo compressor yekugadzirisa maitiro pachayo yakanyanya kuoma: inoda humwe ruzivo, yakakosha maturusi uye zvishandiso.

Hatifanire kukanganwa nezve kukuvadza kwemakemikari anoumbwa nefreon gasi, iyo yauchazofanira kutarisana nayo panguva yekugadzirisa. Iyi gasi inogona kukuvadza ganda uye kukonzera kupisa. Ndokusaka zvisingakurudzirwi kuita basa rekugadzirisa paBMW compressor.

Magadzirirwo ejini ega ega anogadziridzwa anopa imwe yeaviri tensioner sarudzo: mechanical kana hydraulic.

Iyo compressor inofambiswa ne-self-tensioning V-ribbed bhandi.

Usati wabvisa tambo, unofanirwa kugadzirisa nzira yekutenderera nemuseve wakadhirowewa nemucherechedzo kana ukaronga kuishandisa zvakare. Kuiswa kwebhanhire kunofanirwa kuitwa chete maererano neyakasungirirwa yekumaka.

Kana bhanhire rakasvibiswa neinotonhorera, hydraulic fluid kana mafuta, inofanira kuchinjwa. Kune V-belt kutapurirana, izvi zvinoitwa pasi pemamiriro anotevera:

•       Kusvibiswa nefiriji kana mafuta;
•       Kuonekwa kwebhanhire rinotsvedza ruzha nekuda kwekuzora kwayo kana kutambanudza;
•       Kutsemuka uye brittleness;
•       Kuputsika kwechimiro kana tambo dzega;
•       Kusununguka uye kupfeka kweparutivi rwepamusoro.

Iyo compressor drive bhandi ine hydraulic tensioner inotsiviwa mune iyi odha. Kutanga, iyo inodzivirira casing ye hydraulic device inobviswa. Iko tension yecompressor drive inosunungurwa nekuisa hex wrench pane idler roller bolt.

Iyo wrench inofanirwa kutenderedzwa zvishoma nezvishoma kuti ive nechokwadi chekuti hydraulic tensioner inobvisa kubva pabhandi uye bhandi reCompressor drive rinogona kubviswa.

Kuti uise bhanhire, zvakakosha kufambisa zvachose tensioner kurudyi uye kuisa bhanhire idzva, maererano nekugadzirisa kwayo. Iva nechokwadi chekuteerera kune chokwadi chokuti bhanhire rinopindirana zvakasimba mumakororo kana kupindira kwemapulleys.

Kana chigadzirwa chacho chakaitwa ne mechanical tensioner, zvichave zvakakosha kuti udzikise tension roller nekushandura wrench socket pane hexagon yemukati uye kubvisa bhanhire rekutyaira. Paunenge uchiisa bhandi idzva, roller inongogadzirisa tension. Iyo tension force ye roller haichinjiki. Iwe unofanirwawo kuve nechokwadi chekuti bhanhire remabhandi pamapulleys rakarurama.
