Kodi magetsi ophatikizika ndi chiyani?
Makina ogwiritsira ntchito mpweya ozungulira ndi gawo la gawo la firiji. Ntchito yake yayikulu ndikuwunika kukakamizidwa mu gireni yolumikizira mapaipi munthawi yeniyeni, onetsetsani kuti compressiner, ndikugwira ntchito ndi zigawo zina kuti muyambe kuwongolera molondola ndikuyimitsa tempressor. Nthawi zambiri imayikidwa mu chitoliro chachikulu kwambiri m'chipinda cha injini ndikutumiza deta yolumikizidwa ndi injini ecu kapena gawo lowongolera mpweya wabwino. Pamene ecu imalandira chizindikiritso chokhazikika, chimayamba compressor ndi zokutira zozizira; Ngati chizindikiro cha kupanikizana chimapezeka, zomwe zimachitika mwachangu zimasungidwa kuti zilepheretse zida za mpweya monga zopondereza poyambira, poteteza njira yonse yoyambira.
Kuwongolera kwa mpweya nthawi zambiri kumatengera mawilo am'manja atatu, njira yake yolamulira imaphatikizaponso chizindikiro cha Analog, mabasi ndi ntchito pozungulira mitundu itatu. Kuyeza kuthamanga kwa chowongolera mpweya, gwiritsani ntchito mankhwala kuyeza chingwe champhamvu, chingwe champhamvu, komanso chinsinsi cha sensor. Munthawi zabwinobwino, chingwe champhamvu ndi 5V kapena 12V, chinsinsi pansi ndi 0V, ndipo chinsinsi chosinthasintha mu mitundu 0,5v kupita 4.5V kapena 1V mpaka 5V. Ngati mtengo woyenerera ndi wosiyana kwambiri ndi mtengo wamtengo wapatali, zitha kutanthauza kuti sensor yawonongeka kapena pali kulumikizidwa kwenikweni.
Njira yogwirizira mpweya imagwira gawo lofunikira pakukhazikitsa njira ya mufiriji. Ngati sensor imalephera, zitha kubweretsa kuzizira mgalimoto, compresser singathe kugwira ntchito, kapena kuyamba pafupipafupi ndi kusiya mavuto. Chifukwa chake, kuyendera pafupipafupi ndi kukonza malo ogwiritsira ntchito mpweya ndi njira yofunika kwambiri kuti muwonetsetse kuti ntchito yamagalimoto.
Mfundo yogwira ntchito ya mpweya wagalimoto imakhazikika pamavuto, nthawi zambiri imakhala ndi filimu yopyapyala komanso gridi yopenda. Kupanikizika kwa makina owongolera mpweya kumasintha, kukakamizidwa kwa sing'anga yoyeserera kumaperekedwa ku filimuyo mu sensor. Ma filimu omwe amapezeka mothandizidwa ndi zochitika, zomwe zimapangitsa kusintha komwe kumagwirizana ndi gululi. Kusintha kumeneku kumatha kupezeka ndikuwerengedwa ndi dera lolumikizidwa ndi dashboard kapena gawo lina.
Kugwiritsa ntchito ma exotive eners othamanga mu makina owongolera mpweya wamagalimoto kumaphatikizapo mitundu yambiri, mtundu uliwonse umakhala ndi ntchito yake ndi malo ake. Mwachitsanzo, kusintha kwa magetsi kwambiri kumayikidwa pa chipika chodziwikiratu kuti musinthe liwiro la fan mota ndikuwonetsetsa kuti kukakamizidwa kukhazikika kumasungidwa. Pamene kukakamizidwa kutsika ndi kotsika kuposa 1.51 MPA, fanizo imasungabe kuthamanga kochepa. Kupanikizika kamodzi kopitilira 1.5 MPA, fan imathandizira kuthamanga kwambiri. Kuphatikiza apo, kusintha kwa kutentha kawiri kumakhala pafupi ndi condeenser ndikuphatikiza kusinthana kwakukulu ndi injini yozizira yowongolera katha kake. Kutentha kozizira chikakhala pakati pa 95 ndi 102 ° C, katswiri amazungulira liwiro lotsika; Kutentha kukapitilira 102 ° C, fanizo limagwira ntchito mothamanga kwambiri.
Udindo wa zowongolera zamagetsi zomwe zimapangitsa sensor mu makina owongolera mpweya ndikuteteza dongosolo ndikusintha. Amapewa kukakamiza kwambiri kuti asawonongeke pazigawo powunikira kusintha kwa dongosolo. Mwachitsanzo, kukakamizidwa kwa mzere wopanikizawu kuli pansipa 0,2 MPA kapena kupitilira apo12 MPA, ma elekitiror's elekitror's elekitrormar asokonekera kuteteza dongosolo; Clutchtot imachitika pakati pa 0,22 ndi 3.2 MPA. Kuphatikiza apo, kutentha kwakunja kumasintha kutsitsa compressor ecresmagneromagnetic pomwe kutentha kumakhala pansi pa 5 ° C, kupewa kusiyana kwa mpweya
Ngati mukufuna kudziwa zambiri, pitilizani kuwerenga nkhani zina patsamba lino!
Chonde ndiyitane ngati mukufuna zinthu ngati izi.
