Momwe mungayang'anire sensor yothamanga kwambiri G65 ya air conditioning system
Zamkatimu
Kukhazikitsidwa kwa matekinoloje apamwamba kwambiri pamakampani opanga magalimoto kumapangitsa kuti zitheke kusintha machitidwe amitundu yonse, kukulitsa luso lawo komanso magwiridwe antchito awo. Koma, njira imodzi kapena imzake, iliyonse, ngakhale msonkhano wodalirika kwambiri komanso wapamwamba kwambiri wa galimoto ukhoza kukhala ndi zolephera zamtundu uliwonse ndi zolephera, zomwe sizingatheke kuzizindikira.
Kuti muthane ndi vutoli nokha, muyenera kubwezeretsanso mwadongosolo katundu wanu waluso ndi luso, kulabadira mfundo zazikuluzikulu za magwiridwe antchito ndi zida zosiyanasiyana.
M'nkhaniyi, tikambirana za zovuta za kayendedwe ka nyengo m'galimoto. Pankhaniyi, tikambirana chimodzi mwa mavuto wamba mu chimango cha mutu anapatsidwa: malfunctions wa kachipangizo G65.
Udindo wa sensa yapamwamba kwambiri mu air conditioning system
Dongosolo loperekedwa limasiyanitsidwa ndi kukhalapo kwamitundu yosiyanasiyana yomwe imalola kuti mpweya woziziritsa ukhale wosasunthika mkati mwagalimoto. Chimodzi mwazinthu zofunika kwambiri pakusintha kwanyengo ndi sensor yolembedwa G65.
Cholinga chake makamaka kuteteza dongosolo ku zowonongeka zomwe zimadza chifukwa cha kupsyinjika. Chowonadi ndi chakuti dongosolo loperekedwa limasungidwa mumkhalidwe wogwirira ntchito pamaso pa mtengo wapakati wogwirira ntchito mumayendedwe othamanga kwambiri, kutengera kutentha kwanyengo. Choncho, pa kutentha kwa 15-17 0C, kuthamanga koyenera kudzakhala pafupifupi 10-13 kg / cm2.
Kuchokera mu sayansi ya sayansi imadziwika kuti kutentha kwa mpweya kumadalira mwachindunji kupanikizika kwake. Nthawi ina, refrigerant, mwachitsanzo, freon, imakhala ngati mpweya. Pamene kutentha kumakwera, kupanikizika kwa kayendedwe ka nyengo kumayamba kukwera, zomwe ziri zosafunika. Panthawi imeneyi, DVD ikuyamba kugwira ntchito. Ngati muyang'ana chithunzi cha makina oyendetsa mpweya wa galimoto, zikuwonekeratu kuti sensa iyi imamangirizidwa ndi fani, kutumiza chizindikiro pa nthawi yoyenera kuti muzimitse.
Kuzungulira ndi kukonza kukakamiza kwa firiji mu dongosolo lomwe likuganiziridwa kumachitika chifukwa cha compressor, pomwe clutch yamagetsi imayikidwa. Chipangizo choyendetsa ichi chimapereka kutumiza kwa torque kupita ku shaft ya kompresa kuchokera ku injini yamagalimoto, kudzera pagalimoto lamba.
Kugwira ntchito kwa ma electromagnetic clutch ndizomwe zimachitika chifukwa cha sensor yomwe ikufunsidwa. Ngati kupanikizika kwadongosolo kwadutsa malire ovomerezeka, sensa imatumiza chizindikiro ku clutch ya compressor ndipo chomalizacho chimasiya kugwira ntchito.
Mwa zina, ngati vuto likuchitika pakugwira ntchito kwa node imodzi kapena ina, vuto likhoza kuchitika pamene mukuyenda mothamanga kwambiri, chizindikiro ichi chidzayamba kuyandikira mtengo wadzidzidzi, zomwe zingayambitse mavuto aakulu.
Izi zikangochitika, DVD yomweyo imayamba kugwira ntchito.
Chipangizo ndi mfundo ya ntchito ya kachipangizo G65
Kodi chipangizo chosavutachi ndi chiyani? Tiyeni timudziwe bwino.
Monga mu sensa ina iliyonse yamtunduwu, G65 imagwiritsa ntchito mfundo yosinthira mphamvu yamakina kukhala chizindikiro chamagetsi. Mapangidwe a chipangizo ichi cha micromechanical chimaphatikizapo nembanemba. Ndi imodzi mwazinthu zofunika kwambiri za sensor.
Mlingo wa kupatuka kwa nembanemba, kutengera kukakamizidwa komwe kumaperekedwa, kumaganiziridwa popanga kutulutsa kwamphamvu komwe kumatumizidwa kugawo lapakati lowongolera. Chigawo chowongolera chimawerengera ndikusanthula kugunda komwe kukubwera molingana ndi mawonekedwe achilengedwe, ndikupanga kusintha kwa magwiridwe antchito pogwiritsa ntchito chizindikiro chamagetsi. Ma node operekedwa a dongosololi, pankhaniyi, akuphatikiza clutch yamagetsi ya air conditioner ndi fan yamagetsi.
Tiyeneranso kukumbukira kuti ma DVD amakono nthawi zambiri amagwiritsa ntchito crystal silicon m'malo mwa nembanemba. Silicon, chifukwa cha mphamvu zake za electrochemical, ili ndi chinthu chimodzi chochititsa chidwi: pansi pa kukakamizidwa, mchere uwu umatha kusintha kukana kwa magetsi. Kuchita mogwirizana ndi mfundo ya rheostat, kristalo iyi yomangidwa mu board sensor imakulolani kutumiza chizindikiro chofunikira ku chipangizo chojambulira cha unit control unit.
Tiyeni tiganizire momwe zinthu zilili pamene DVD yayambika, malinga ngati ma node onse a dongosolo loperekedwa ali bwino ndipo akugwira ntchito mwachizolowezi.
Monga tafotokozera kale, sensor iyi ili mumayendedwe othamanga kwambiri a dongosolo. Ngati tijambula fanizo ndi dongosolo lililonse lotsekedwa lamtunduwu, tikhoza kunena kuti limayikidwa pa "zopereka" za firiji. Yotsirizirayi imalowetsedwa mumayendedwe othamanga kwambiri ndipo, kudutsa mumzere wopapatiza, imapanikizidwa pang'onopang'ono. Kuthamanga kwa Freon kumakwera.
Pankhaniyi, malamulo a thermodynamics amayamba kudziwonetsera okha. Chifukwa cha kuchuluka kwa firiji, kutentha kwake kumayamba kukwera. Kuti achotse chodabwitsa ichi, condenser imayikidwa, yofanana ndi radiator yozizira. Izo, pansi pa njira zina zogwirira ntchito za dongosololi, zimawombedwa mwamphamvu ndi fani yamagetsi.
Choncho, pamene choziziritsa mpweya wazimitsidwa, kuthamanga refrigerant mu madera onse a dongosolo dongosolo ndi ofanana ndipo pafupifupi 6-7 atmospheres. Air conditioner ikangoyatsidwa, kompresa imayamba kugwira ntchito. Popopera freon mu dera lothamanga kwambiri, mtengo wake umafika pa bar 10-12. Chizindikirochi chikukula, ndipo kupanikizika kowonjezera kumayamba kuchitapo kanthu pa kasupe wa HPD membrane, kutseka kulamulira kwa sensa.
Kuthamanga kuchokera ku sensa kumalowa mu unit control, yomwe imatumiza chizindikiro kwa fani yoziziritsa ya condenser ndi clutch yamagetsi ya compressor drive. Chifukwa chake, kompresa imachotsedwa mu injini, kuyimitsa kupopera firiji mumayendedwe othamanga kwambiri, ndipo fani imasiya kugwira ntchito. Kukhalapo kwa sensor yothamanga kwambiri kumakupatsani mwayi wosunga magawo ogwiritsira ntchito gasi ndikukhazikika kwa dongosolo lonse lotsekedwa lonse.
Momwe mungayang'anire sensa ya air conditioning kuti isagwire bwino ntchito
Nthawi zambiri, eni magalimoto omwe ali ndi dongosolo loperekedwa amakumana ndi mfundo yakuti panthawi imodzi yabwino, mpweya wozizira umangosiya kugwira ntchito. Nthawi zambiri, chomwe chimayambitsa vutoli chimakhala pakuwonongeka kwa DVD. Taganizirani zina mwazofala kwambiri za kulephera kwa DVD ndi momwe mungazindikire.
Pa gawo loyambirira loyang'ana magwiridwe antchito a sensor yomwe yatchulidwa, iyenera kuyang'aniridwa. Ndikofunika kuonetsetsa kuti palibe kuwonongeka kapena kuipitsidwa pamwamba pake. Kuphatikiza apo, muyenera kulabadira ma waya a sensa ndikuwonetsetsa kuti ili bwino.
Ngati kuyang'ana kowoneka sikunawulule zomwe zimayambitsa kulephera pakugwira ntchito kwake, kuwunikira mwatsatanetsatane kuyenera kugwiritsidwa ntchito pogwiritsa ntchito ohmmeter.
Mchitidwe wa zochitika mu nkhani iyi udzawoneka motere:
- Chotsani mawaya apansi pamadzi ku DVD;
- Lumikizani ma ohmmeter clamps ku ma terminals a sensor, pomwe gawo lokhazikika liyenera kukhala osachepera 100 kOhm;
- Yezerani kukana kwa sensor ndi tester.
Malinga ndi zotsatira za miyeso, tinganene kuti DVD ili bwino.
Chifukwa chake, sensor imagwira ntchito ngati:
- Pamaso pa kupanikizika kowonjezera pamzere, ohmmeter iyenera kulembetsa kukana kwa osachepera 100 kOhm;
- Ngati pali kupanikizika kosakwanira mu dongosolo, mawerengedwe a multimeter sayenera kupitirira chizindikiro cha 10 ohm.
Muzochitika zina zonse, tikhoza kuganiza kuti DVD yasiya kugwira ntchito. Ngati, malinga ndi zotsatira za mayesero, zinapezeka kuti sensa ikugwira ntchito, muyenera kuyang'ana sensa ya "fupifupi". Kuti muchite izi, muyenera kuponyera terminal imodzi pa imodzi mwazotulutsa za DVD, ndikukhudza yachiwiri ku "misa" yagalimoto.
Ngati pali kupanikizika kosakwanira mu dongosolo lomwe laperekedwa, sensa yogwira ntchito idzapereka osachepera 100 kOhm. Apo ayi, tinganene kuti sensor ili kunja kwa dongosolo.
Malangizo obwezeretsa
Ngati, chifukwa cha miyeso pamwambapa matenda, zinali zotheka kupeza kuti sensa analamula moyo wautali, m`pofunika m`malo mwamsanga.
Ndikoyenera kudziwa kuti chifukwa cha izi sikofunikira konse kulumikizana ndi mautumiki apadera ndi malo ogulitsa magalimoto. Mchitidwewu ukhoza kuchitidwa bwino mu garaja.
Kusintha kwa algorithm kumakhala ndi izi:
- Kugwetsa zinthu zathupi zomwe zimalepheretsa kupeza sensor;
- Kutseka kwa zotulutsa zapansi pamadzi za sensa;
- Kuchotsa sensa ndi galimoto;
- Kugwirizana kwa mfundo za m'madzi;
- Kuyika zinthu zathupi.
Payokha, kusintha sensa sikuyenera kuyambitsa zovuta, komabe ndikofunikira kutsatira malangizo ena ovomerezeka.
Choyamba, pogula sensa yatsopano yomwe siinali yoyambirira, muyenera kuonetsetsa kuti ikugwirizana ndi magawo omwe atchulidwa. Kuphatikiza apo, zimachitika kuti DVD yatsopano nthawi zonse imakhala ndi kolala yosindikiza. Chifukwa chake, pankhaniyi, ndikofunikira kuyang'anira kupezeka kwake, popeza pali kuthekera kuti chosindikizira chakale changokhala chosagwiritsidwa ntchito.
Nthawi zambiri zimachitika kuti m'malo DVD, mpweya dongosolo kubwezeretsa ntchito yake pang'ono. Pankhaniyi, ndi mwayi waukulu, zikhoza kutsutsidwa kuti mlingo wa refrigerant mu dongosolo ndi wotsika. Kuti muthane ndi vutoli, muyenera kuthira mafuta pamagalimoto apadera.
