Kodi sensor yamagalimoto yama air conditioning ndi chiyani
Sensor yamagetsi yamagalimoto yamagalimoto ndiye chigawo chachikulu cha firiji. Ntchito yake yayikulu ndikuwunika kuthamanga kwa refrigerant mupaipi yoziziritsa mpweya munthawi yeniyeni, kuonetsetsa kuti makinawo akugwira ntchito bwino, ndikugwira ntchito ndi zigawo zina kuti athe kuwongolera kuyambika ndi kuyimitsidwa kwa fani yakuzizira ndi kompresa. Nthawi zambiri imayikidwa mu chitoliro cha mpweya wothamanga kwambiri m'chipinda cha injini ndikutumiza deta yosonkhanitsidwa ku injini ECU kapena chipangizo chapadera chowongolera mpweya. Pamene ECU imalandira chizindikiro chodziwika bwino, imayamba compressor ndi fan fan; Ngati chizindikiro cha kuthamanga kwachilendo chizindikirika, njira zachangu zimatengedwa kuti aletse zida zowongolera mpweya monga ma compressor kuti ayambe, potero kuteteza dongosolo lonse la firiji. pa
Air conditioning pressure sensor nthawi zambiri imagwiritsa ntchito mapangidwe a waya atatu, mawonekedwe ake owongolera amaphatikizanso chizindikiro cha analogi, mabasi a Lin ndi mitundu itatu yoyendetsa ntchito. Kuti muyese mphamvu ya sensor ya air conditioner, gwiritsani ntchito multimeter kuyeza chingwe cha mphamvu, chingwe chapansi, ndi chingwe cha chizindikiro cha sensa. Nthawi zambiri, chingwe chamagetsi ndi 5V kapena 12V, chingwe chapansi ndi 0V, ndipo chingwe cholumikizira chimasinthasintha pakati pa 0.5V mpaka 4.5V kapena 1V mpaka 5V. Ngati mtengo woyezera ndi wosiyana kwambiri ndi mtengo wamtengo wapatali, zikhoza kutanthauza kuti sensa yawonongeka kapena pali kugwirizana kwenikweni mu harni.
Sensor ya air conditioning pressure imagwira ntchito yofunika kwambiri mufiriji yamagalimoto. Ngati sensa ikulephera, ikhoza kuyambitsa kuzizira m'galimoto, kompresa singagwire ntchito, kapena kuyambitsa ndi kuyimitsa pafupipafupi. Chifukwa chake, kuyang'anira nthawi zonse ndikukonza makina owongolera mpweya ndi gawo lofunikira kuti muwonetsetse kuti makina owongolera mpweya amayendera bwino pamagalimoto.
Mfundo yogwiritsira ntchito makina oyendetsa mpweya wamagalimoto amatengera kukakamizidwa, nthawi zambiri kumakhala filimu yopyapyala ndi gululi la resistors. Pamene kupanikizika mu makina oyendetsa mpweya wamagalimoto akusintha, kupanikizika kwa sing'anga yoyezera kumatumizidwa kufilimu mu sensa. Kanemayo amawonongeka chifukwa cha kukakamizidwa, zomwe zimapangitsa kusintha kofananira kwa gridi yotsutsa pafilimuyo. Kusintha kumeneku kungathe kuzindikirika ndikuwerengedwa ndi dera lolumikizidwa ndi dashboard kapena gawo lina lowongolera. pa
Kugwiritsa ntchito makina owongolera mpweya wamagalimoto pamagalimoto owongolera mpweya kumaphatikizapo mitundu yambiri, mtundu uliwonse uli ndi ntchito yake komanso malo ake oyika. Mwachitsanzo, chosinthira chamagetsi chapamwamba chimayikidwa pa chitoliro cha condenser cholowera kuti chiwongolere liwiro la injini ya fan ndikuwonetsetsa kuti kuthamanga kwa condenser kumasungidwa pamalo otetezeka. Kuthamanga kwa condensing kumakhala kotsika kuposa 1.51 mpa, faniyo imakhalabe yothamanga kwambiri. Kuthamanga kukadutsa 1.5 mpa, fani imathamanga kwambiri. Kuphatikiza apo, chosinthira chapawiri kutentha chimakhala pafupi ndi cholumikizira ndikuphatikiza chosinthira champhamvu kwambiri ndi kutentha kozizira kwa injini kuti chiwongolere magwiridwe antchito a injini yowongoka. Pamene kutentha kozizira kuli pakati pa 95 ndi 102 ° C, faniyo imazungulira pa liwiro lochepa; Pamene kutentha kupitirira 102 ° C, faniyo imagwira ntchito mofulumira kwambiri.
Ntchito yamagalimoto yama air conditioning pressure sensor mu automotive air conditioning system ndikuteteza dongosolo ndikuwongolera magwiridwe antchito. Amalepheretsa kukakamizidwa kwambiri kuti zisawononge kuwonongeka kwa zigawo poyang'anira kusintha kwamphamvu mkati mwadongosolo. Mwachitsanzo, pamene kuthamanga kwa mzere wapamwamba kumakhala pansi pa 0,2 mpa kapena pamwamba pa 3.2 mpa, clutch yamagetsi ya compressor imachotsedwa kuti iteteze dongosolo; Clutch imakhalabe yogwira ntchito pakati pa 0.22 ndi 3.2 mpa. Kuphatikiza apo, kusintha kwa kutentha kwakunja kumachotsa cholumikizira chamagetsi cha kompresa pamene kutentha kuli pansi pa 5 ° C, kulepheretsa mpweya wozizira kuti usagwire ntchito pa kutentha kochepa.
Ngati mukufuna kudziwa zambiri, pitilizani kuwerenga zolemba zina patsamba lino!
Chonde tiyimbireni ngati mukufuna zinthu zotere.
Malingaliro a kampani Zhuo Meng Shanghai Auto Co., Ltd. adadzipereka kugulitsa zida zamagalimoto za MG&750 zolandilidwa kugula.
