Inzwa yokulawula injini

Kunezinhlobo eziningi zezinzwa zokulawula injini, okuhlanganisa inzwa yokushisa, inzwa yokucindezela, inzwa yejubane ne-engeli, inzwa yokugeleza, inzwa yendawo, inzwa yokuhlushwa kwegesi, inzwa yokugoqa nokunye. Lolu hlobo lwenzwa luwumgogodla wayo yonke injini. Ukuzisebenzisa kungathuthukisa amandla enjini, kunciphise ukusetshenziswa kukaphethiloli, kunciphise igesi yokukhipha umoya, kubonise amaphutha, njll. Ngenxa yokuthi asebenza ezindaweni ezinokhahlo njengokudlidliza kwenjini, umhwamuko kaphethiloli, udaka namanzi anodaka, inkomba yawo yobuchwepheshe yokumelana nemvelo enokhahlo ingaphezulu eyezinzwa ezijwayelekile. Kunezidingo eziningi zezinkomba zabo zokusebenza, phakathi kwazo okubaluleke kakhulu ukunemba kokulinganisa nokuthembeka, ngaphandle kwalokho iphutha elibangelwa ukutholwa kwenzwa ekugcineni lizoholela ekuhlulekeni kwesistimu yokulawula injini noma ukwehluleka.

1. Inzwa yokushisa: ithola ngokuyinhloko izinga lokushisa kwenjini, izinga lokushisa legesi ethathwayo, izinga lokushisa lamanzi okupholisa, izinga lokushisa likawoyela kaphethiloli, izinga lokushisa likawoyela wenjini, izinga lokushisa le-catalytic, njll. Izinzwa zokushisa ezisebenzayo ikakhulukazi ukumelana nesilonda sezintambo, i-thermistor kanye ne-thermocouple. Inzwa yokushisa yokumelana nenxeba yocingo inokunemba okuphezulu, kodwa izici zokusabela ezingezinhle; Inzwa ye-Thermistor inokuzwela okuphezulu nezici zokuphendula ezinhle, kodwa umugqa ompofu kanye nezinga lokushisa elisebenzayo eliphansi. Uhlobo lwe-Thermocouple lunokunemba okuphezulu kanye nebanga lokulinganisa izinga lokushisa elibanzi, kodwa i-amplifier nokwelashwa kokugcina okubandayo kufanele kucatshangelwe.

2. Inzwa yokucindezela: ibona ngokuyinhloko ukucindezela okuphelele kokuthatha okuningi, i-vacuum degree, i-atmospheric pressure, umfutho kawoyela wenjini, umfutho kawoyela wamabhuleki, umfutho wesondo, njll. Kunezinhlobo eziningana zezinzwa zokucindezela kwemoto, phakathi kwazo okune-capacitive, piezoresistive, variable inductance. eqhutshwa yi-diaphragm (LVDT) kanye ne-surface elastic wave (SAW) asetshenziswa kabanzi. Inzwa ye-Capacitive inezici zamandla okufaka aphezulu, impendulo enhle eguquguqukayo kanye nokuvumelana nezimo okuhle kwemvelo. I-varistor ithonywa kakhulu izinga lokushisa, ngakho-ke idinga ukusetha umjikelezo wesinxephezelo sokushisa, kodwa kufanelekile ukukhiqizwa ngobuningi. Uhlobo lwe-LVDT lunomkhiqizo omkhulu, okulula okukhiphayo kwedijithali, kodwa ukumelana nokudlidliza kwawo kuphansi. I-SAW iyinzwa ekahle ngenxa yobukhulu bayo obuncane, isisindo esincane, ukusetshenziswa kwamandla okuphansi, ukwethembeka okuqinile, ukuzwela okukhulu, ukulungiswa okuphezulu kanye nokukhishwa kwedijithali.
