Galimoto intake pressure sensor ntchito
Ntchito zazikulu za sensor yamagetsi yamagalimoto yamagalimoto ndi izi:
Perekani chizindikiro cha katundu wa injini : Sensa yolowetsa mphamvu imapereka chizindikiro cha injini ku ECU (Chigawo choyang'anira injini) poyesa kusintha kwa mphamvu muzowonjezereka. Zizindikirozi zimathandiza ECU kuwongolera m'lifupi mwake m'lifupi mwake ndi kutseguka kwamphamvu kuti ikwaniritse bwino ntchito ya injini komanso kuchepa kwamafuta.
Yang'anirani jakisoni wamafuta ndi nthawi yoyatsira : Masensa amasintha kusintha kwamakasitomala kukhala ma siginecha amagetsi kuti ECU ikonze jekeseni wamafuta ndi Nthawi yoyatsira. Kuchuluka kwa injini kumachulukirachulukira, kupanikizika kwapang'onopang'ono kumachepa, chizindikiro cha sensor chimawonjezeka, ndipo ECU imawonjezera kuchuluka kwa jekeseni wamafuta ndikuchedwetsa kuyatsa koyambira. Kupanda kutero, jekeseni wamafuta adzachepetsedwa ndipo kuyatsa kudzakhala patsogolo.
Sinthani nthawi yotsegulira valavu ndi jekeseni wamafuta: Mu injini yokhala ndi makina owongolera ma valve amagetsi, sensor yothamanga imazindikira kusintha kwapaipi yolowera ndikuwerengera molondola kuchuluka kwa mpweya mu silinda iliyonse kuti musinthe nthawi yotsegulira valavu ndi kuchuluka kwa jekeseni wamafuta. Izi zimathandiza kupititsa patsogolo mphamvu ndi mphamvu ya injini.
Chitetezo cha injini : Sensa yothamangitsa yomwe imalowetsa imathanso kuzindikira momwe injini imagwirira ntchito, monga kusintha kwamphamvu kwamphamvu, ndikutumiza zidziwitso kumakina owongolera kuti ateteze injini. Izi zimathandiza kupewa kuwonongeka kwa injini chifukwa chodzaza kwambiri kapena zovuta zina.
Mfundo yogwirira ntchito : Sensa yamphamvu yotengera nthawi zambiri imalumikizidwa ndi kuchuluka komwe amamwa kudzera mu chubu cha vacuum ndipo imamva kusintha kwa vacuum mu kuchuluka kwa momwe amamwa. Pamene liwiro la injini ndi katundu zikusintha, kupanikizika muzowonjezereka kudzasintha, ndipo kukana mkati mwa sensa kudzasinthanso moyenera, motero kutulutsa chizindikiro chamagetsi. Chizindikirochi chimalandiridwa ndi ECU ndipo chimagwiritsidwa ntchito kusintha jakisoni wamafuta ndi nthawi yoyatsira.
Zowonongeka Zowonongeka : Ngati mphamvu yogwiritsira ntchito mphamvu yawonongeka, ingayambitse kuthamanga kosasunthika, kuthamanga kofooka, kuvutika poyambira, kuwonjezeka kwa mafuta ndi mavuto ena a galimoto. Nthawi yomweyo, kuwala kwa injini kudzayatsidwa, ndipo nambala yolakwika yofananira idzasungidwa.
Chifukwa chake, kuyang'anira nthawi zonse ndikukonza cholumikizira cholumikizira ndikofunikira kuti zitsimikizire kuti galimotoyo ikuyenda bwino.
Manifold Absolute Pressure Sensor (MAP) ndi gawo lofunikira mu injini yamagalimoto yomwe imayang'anira kusintha kwamphamvu kwa kuchuluka kwa zomwe amadya ndikusintha zosinthazi kukhala ma siginecha amagetsi kuti aziwongoleredwa bwino ndi injini yamagetsi yamagetsi (ECU). Sensor ya intake pressure imalumikizidwa ndi njira zambiri zolowera kudzera pa vacuum chubu ndipo imatha kuzindikira kusintha kwa vacuum mu kuchuluka kwa momwe amamwa. Ndi liwiro la injini ndi katundu wosiyanasiyana, kukana mkati mwa sensa kudzasintha, komwe kumasinthidwa kukhala chizindikiro chamagetsi kuti ECU ikonze kuchuluka kwa jakisoni wamafuta ndi nthawi yoyatsira.
Mfundo yogwira ntchito
Mfundo yogwiritsira ntchito mphamvu yogwiritsira ntchito mphamvu yowonjezera imachokera ku kusintha kwa kukana komwe kumachitika chifukwa cha kusintha kwamphamvu. Tengani varistor type inlet pressure sensor mwachitsanzo, chigawo chake chachikulu ndi silicon diaphragm yopangidwa ndi piezoresistive athari ya semiconductor. Pamene kupanikizika kwa manifold amalowedwe kumagwira ntchito pa silicon diaphragm, diaphragm imapunduka, zomwe zimapangitsa kusintha kwa kukana kwake. Kusintha kumeneku kumasinthidwa kukhala chizindikiro chamagetsi, chomwe chimakulitsidwa ndikupititsidwa ku ECU. Kutengera mphamvu yamagetsi yolandilidwa, ECU imayang'anira jakisoni wamafuta kuti agwirizane ndi zosowa zosiyanasiyana zoyendetsa.
Mitundu ndi ntchito
Pali mitundu yambiri ya masensa omwe amadya, omwe amadziwika kuti semiconductor varistor, vacuum bellows ndi capacitive. Pakati pawo, varistor ya semiconductor imagwiritsidwa ntchito kwambiri mu jekeseni wa D-mtundu chifukwa cha ubwino wake woyankha mofulumira, kulondola kwambiri, kukula kochepa komanso kusinthika kosinthika. Sensor capacitive imagwiritsa ntchito diaphragm kuti ipange chinthu chovuta kukakamiza chokhala ndi mtengo wosinthika, ndikusintha kusintha kwamphamvu kukhala chizindikiro chamagetsi poyesa dera.
Kusamalira ndi kuzindikira zolakwika
Kuzindikira kolakwika kwa sensa ya intake pressure sensor nthawi zambiri kumaphatikizapo kuwunika ngati chizindikiro chake chili mkati mwanthawi zonse. Ngati chizindikiro chotulutsa sensa ndi chosazolowereka, magwiridwe antchito a injini amatha kukhala odetsedwa kapena osakhazikika. Pokonza, nthawi ndi nthawi yang'anani kulumikizana ndi kusindikiza kwa sensa kuti muwonetsetse kuti ikugwira ntchito bwino.
paNgati 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.
