Inzwa yokucindezela 31Q4-40820 ifanele izingxenye zesimanje zokumba

I-pressure transducer

Inzwa yokucindezela isetshenziswa kakhulu ukuthola umfutho we-cylinder negative, i-atmospheric pressure, i-boost ratio yenjini ye-turbine, i-cylinder yangaphakathi yokucindezela kanye nomfutho kawoyela. Inzwa ye-suction negative pressure isetshenziswa kakhulu ukuthola ingcindezi yokuncela, ingcindezi engemihle kanye nomfutho kawoyela. I-Capacitance, i-piezoresistance, i-differential transformer (LVDT) kanye ne-surface elastic wave (SAW) isetshenziswa kabanzi kuzinzwa zengcindezi yemoto.

I-capacitive pressure sensor isetshenziselwa kakhulu ukuthola ingcindezi engemihle, i-hydraulic pressure kanye ne-air pressure, enebanga lokulinganisa lika-20 ~ 100kPa, elinezici zamandla okufaka aphezulu, ukusabela okuhle okuguquguqukayo kanye nokuvumelana nezimo kwemvelo okuhle. Inzwa yengcindezi ye-piezoresistive ithonywa kakhulu izinga lokushisa, elidinga esinye isinxephezelo sesifunda sokushisa, kodwa kufanelekile ukukhiqizwa ngobuningi. Inzwa yokucindezela ye-LVDT inokukhipha okukhulu, okulula ukuyikhipha ngedijithali, kodwa inokuphikisana nokuphazanyiswa okubi. Inzwa yokucindezela ye-SAW inezici zevolumu encane, isisindo esincane, ukusetshenziswa kwamandla okuphansi, ukwethembeka okuphezulu, ukuzwela okuphezulu, ukulungiswa okuphezulu, ukuphuma kwedijithali, njll. Iyinzwa efanelekile yokutholwa kwengcindezi ye-valve yemoto futhi ingasebenza ngokuzinzile ekushiseni okuphezulu. .

Inzwa yokugeleza

Inzwa yokugeleza isetshenziswa kakhulu ukukala ukugeleza komoya nokugeleza kukaphethiloli wenjini. Isilinganiso sokugeleza komoya sisetshenziselwa uhlelo lokulawula injini ukunquma izimo zokuvutha, ukulawula isilinganiso samafutha omoya, ukuqala, ukuthungela nokunye. Kunezinhlobo ezine zezinzwa zokugeleza komoya: i-rotary vane (uhlobo lwe-vane), uhlobo lwe-Carmen vortex, uhlobo lwezintambo ezishisayo kanye nohlobo lwefilimu eshisayo. I-rotary vane air flowmeter inesakhiwo esilula nokunemba kwesilinganiso esiphansi, ngakho ukugeleza komoya okukaliwe kudinga isinxephezelo sezinga lokushisa. I-Carmen vortex air flowmeter ayinazo izingxenye ezihambayo, ezibucayi futhi ezinembile, futhi zidinga isinxephezelo sokushisa. I-hot-wire air flowmeter inokunemba okuphezulu kwesilinganiso futhi ayidingi isinxephezelo sezinga lokushisa, kodwa ithinteka kalula ukushaywa kwegesi nezintambo eziphukile. I-hot-film air flowmeter inesimiso sokulinganisa esifanayo ne-hot-wire air flowmeter, kodwa incane ngosayizi, ifanele ukukhiqizwa ngobuningi futhi iphansi ngezindleko. Izinkomba eziyinhloko zobuchwepheshe zenzwa yokugeleza komoya yilezi: ububanzi bokusebenza ngu-0.11 ~ 103 m3 / min, izinga lokushisa elisebenzayo lingu-40 ℃ ~ 120 ℃, futhi ukunemba ≤1%.

Inzwa yokugeleza kukaphethiloli isetshenziselwa ukubona ukugeleza kukaphethiloli, ikakhulukazi okuhlanganisa uhlobo lwesondo lamanzi kanye nohlobo lwebhola elijikelezayo, enobubanzi obuguquguqukayo obungu-0~60kg/h, izinga lokushisa elisebenzayo elingu--40℃~120℃, ukunemba okungu-1% nesikhathi sokuphendula esingu-<10ms .
