Daga tsarin ilimin kimiyyar lissafi an san cewa zafin iskar gas yana dogara ne kai tsaye akan matsinsa. A cikin wani akwati na musamman, refrigerant, alal misali, freon, yana aiki azaman iskar gas. Yayin da zafin jiki ya tashi, matsa lamba a cikin tsarin kula da yanayi ya fara tashi, wanda ba a so. A wannan lokaci, DVD ya fara aiki. Idan ka kalli zanen tsarin kwandishan motar, zai bayyana a fili cewa wannan firikwensin yana daure da fan, yana aika sigina a daidai lokacin da ya dace don kashe ta.
Zazzagewa da kuma kula da matsa lamba na refrigerant a cikin tsarin da ake la'akari da shi ana yin godiya ga kwampreso, wanda aka shigar da kamannin lantarki. Wannan na'urar tuƙi tana ba da isar da juzu'i zuwa mashin kwampreso daga injin mota, ta hanyar bel ɗin.
Aiki na electromagnetic clutch shine sakamakon aikin firikwensin da ake tambaya. Idan matsa lamba a cikin tsarin ya wuce ma'auni da aka yarda, firikwensin yana aika sigina zuwa clutch na compressor kuma ƙarshen ya daina aiki.
Daga cikin wasu abubuwa, idan rashin aiki ya faru a cikin aiki na ɗaya ko wani kumburi na tsarin, wani yanayi na iya tasowa lokacin da a cikin babban matsin lamba, wannan alamar aiki zai fara kusantar darajar gaggawa, wanda zai haifar da sakamako mai tsanani.
Da zaran irin wannan yanayi ya taso, DVD ɗaya ya fara aiki.
Na'urar da ka'idar aiki na firikwensin G65
Menene wannan na'ura mai sauƙi? Mu kara saninsa sosai.
Kamar yadda yake a cikin kowane firikwensin irin wannan, G65 yana aiwatar da ka'idar canza makamashin injin zuwa siginar lantarki. Zane na wannan na'urar micromechanical ya haɗa da membrane. Yana ɗaya daga cikin mahimman abubuwan aiki na firikwensin.
Matsayin jujjuyawar membrane, dangane da matsa lamba da aka yi akansa, ana la'akari da shi lokacin samar da bugun jini da aka aika zuwa sashin kulawa na tsakiya. Ƙungiyar sarrafawa tana karantawa da kuma nazarin bugun jini mai shigowa daidai da halaye masu mahimmanci, kuma yana yin canje-canje ga aikin nodes na tsarin ta hanyar siginar lantarki. Abubuwan da aka gabatar na tsarin, a cikin wannan yanayin, sun haɗa da kama da wutar lantarki na kwandishan da fan na lantarki.
Ya kamata kuma a lura cewa DVD na zamani kan yi amfani da crystal crystal maimakon membrane. Silicon, saboda kaddarorinsa na electrochemical, yana da fasalin mai ban sha'awa: a ƙarƙashin rinjayar matsa lamba, wannan ma'adinai yana iya canza juriya na lantarki. Yin aiki akan ka'idar rheostat, wannan crystal, wanda aka gina a cikin allon firikwensin, yana ba ka damar aika siginar da ake bukata zuwa na'urar rikodi na sashin kulawa.
Bari mu yi la'akari da halin da ake ciki lokacin da aka kunna DVD, idan har duk nodes na tsarin da aka gabatar suna cikin tsari mai kyau kuma suna aiki a cikin yanayin al'ada.
Kamar yadda aka riga aka ambata a sama, wannan firikwensin yana cikin babban matsi na tsarin. Idan muka zana kwatanci tare da kowane rufaffiyar tsarin irin wannan, zamu iya cewa an ɗora shi akan "samar" na refrigerant. Ana yin allura na ƙarshe a cikin babban matsi mai ƙarfi kuma, wucewa ta kunkuntar layi, ana matsawa a hankali. Freon matsa lamba yana tashi.
A wannan yanayin, dokokin thermodynamics sun fara bayyana kansu. Saboda yawan firijin, zafinsa ya fara tashi. Don kawar da wannan al'amari, an shigar da na'ura mai kwakwalwa, a waje kamar radiator mai sanyaya. Ta, a ƙarƙashin wasu hanyoyin aiki na tsarin, ana busa shi da ƙarfi ta hanyar fanko na lantarki.
Don haka, lokacin da aka kashe na'urar kwandishan, matsa lamba na refrigerant a cikin sassan biyu na tsarin yana daidaitawa kuma yana kusan yanayi 6-7. Da zarar na'urar sanyaya iska ta kunna, compressor ya fara aiki. Ta hanyar yin famfo freon a cikin da'irar babban matsin lamba, ƙimar sa ta kai mashaya 10-12 mai aiki. Wannan mai nuna alama yana girma a hankali, kuma matsa lamba mai yawa ya fara aiki akan bazara na membrane na HPD, yana rufe lambobin sarrafawa na firikwensin.
Buga bugun jini daga firikwensin yana shiga sashin sarrafawa, wanda ke aika sigina zuwa fan ɗin sanyaya mai sanyaya da kwampreso drive ɗin lantarki. Don haka, ana cire kwampreso daga injin, yana dakatar da yin famfo a cikin da'irar babban matsin lamba, kuma fan ya daina aiki.

Yadda ake bincika firikwensin kwandishan don rashin aiki
Sau da yawa, masu motoci masu sanye da tsarin da aka gabatar suna fuskantar gaskiyar cewa a wani lokaci, na'urar kwandishan kawai ta daina aiki. Sau da yawa, dalilin irin wannan rashin aiki yana cikin rushewar DVD. Yi la'akari da wasu lokuta mafi yawan lokuta na gazawar DVD da yadda za a gano shi.
A matakin farko na duba aikin firikwensin da aka ƙayyade, ya kamata a duba shi ta gani. Wajibi ne a tabbatar da cewa babu lalacewa ko gurbacewa a samansa. Bugu da kari, ya kamata ka kula da wayoyi na firikwensin kuma tabbatar da cewa yana cikin yanayi mai kyau.
Idan duban gani bai bayyana musabbabin gazawa a cikin aikinsa ba, ya kamata a nemi ƙarin cikakken ganewar asali ta amfani da ohmmeter.
Jerin ayyuka a wannan yanayin zai yi kama da haka:
- Cire wayoyi na karkashin ruwa daga DVD;
- Haɗa maƙallan ohmmeter zuwa tashoshi na firikwensin, yayin da kewayon juriya ya kamata ya zama aƙalla 100 kOhm;
- Auna juriya na firikwensin tare da mai gwadawa.
Bisa ga sakamakon ma'auni, za mu iya kammala cewa DVD yana cikin yanayi mai kyau.
Don haka, firikwensin yana aiki muddin:
- A gaban matsanancin matsa lamba a cikin layi, ohmmeter dole ne ya yi rajistar juriya na akalla 100 kOhm;
- Idan akwai rashin isasshen matsa lamba a cikin tsarin, karatun multimeter kada ya wuce alamar 10 ohm.
A duk sauran lokuta, muna iya ɗauka cewa DVD ya rasa aikinsa. Idan, bisa ga sakamakon gwajin, ya nuna cewa firikwensin yana aiki, ya kamata ka duba firikwensin don "gajeren kewayawa". Don yin wannan, kana bukatar ka jefa daya m a kan daya daga cikin abubuwan da DVD, da kuma taba na biyu zuwa ga "jama'a" na mota.
Idan akwai rashin isasshen matsa lamba a cikin tsarin da aka gabatar, firikwensin aiki zai ba da aƙalla 100 kOhm. In ba haka ba, ana iya ƙarasa cewa firikwensin ba ya aiki.
Umarnin sauyawa
Idan, a sakamakon matakan bincike na sama, zai yiwu a gano cewa firikwensin ya ba da umarnin rayuwa mai tsawo, ya zama dole a maye gurbin shi da sauri.
Ya kamata a lura cewa saboda wannan ba lallai ba ne don tuntuɓar sabis na musamman da shagunan gyaran motoci. Ana iya samun nasarar yin wannan hanya a cikin yanayin garage na al'ada.
Algorithm na maye gurbin ya ƙunshi matakai masu zuwa:
- Rage abubuwan jiki waɗanda ke hana damar yin amfani da firikwensin;
- Kashe abubuwan da ke cikin ruwa na firikwensin;
- Cire firikwensin tare da kashe motar;
- Haɗin ƙaddamarwa na ƙarƙashin ruwa;
- Shigar da abubuwan jiki.
Da kanta, maye gurbin firikwensin bai kamata ya haifar da matsaloli ba, amma har yanzu yana da mahimmanci a bi wasu ƙa'idodi na yanayin shawarwari.
Na farko, lokacin siyan sabon firikwensin da ba na asali ba, kuna buƙatar tabbatar da cewa ya dace da ƙayyadaddun sigogi. Bugu da ƙari, yana faruwa cewa sabon DVD ba koyaushe yana sanye da abin wuyan rufewa ba. Sabili da haka, a cikin wannan yanayin, wajibi ne a kula da sayan sa, tun da akwai yiwuwar cewa tsohon sealant kawai ya zama marar amfani.
Sau da yawa yakan faru cewa lokacin maye gurbin DVD, tsarin kwandishan yana dawo da aikin sa kawai. A wannan yanayin, tare da babban matakin yiwuwar, ana iya jayayya cewa matakin refrigerant a cikin tsarin yana da ƙananan. Don magance wannan matsala, kuna buƙatar sake mai da tsarin a cikin sabis na mota na musamman.
