I-RE542461 isetshenziselwa inzwa yokucindezela uwoyela kaJohn Deere.

Izinzwa zokulawula 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 yezinga lokushisa:

ithola ngokuyinhloko izinga lokushisa kwenjini, izinga lokushisa legesi elithathwayo, 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 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:

ithola ikakhulukazi ukucindezela okuphelele kokuthatha okuningi, i-vacuum degree, ingcindezi yomoya, umfutho kawoyela wenjini, umfutho kawoyela wamabhuleki, umfutho wesondo, njll. Kunezinhlobo ezimbalwa zezinzwa zokucindezela kwemoto, phakathi kwazo okune-capacitive, piezoresistive, inductance eguquguqukayo eqhutshwa i-diaphragm (LVDT). ) kanye ne-surface elastic wave (SAW) isetshenziswa 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 lunomphumela omkhulu, okulula okukhiphayo kwedijithali, kodwa ukumelana nokudlidliza akubi;I-SAW iyinzwa ekahle ngenxa yobukhulu bayo obuncane, isisindo esincane, ukusetshenziswa kwamandla okuphansi, ukwethembeka okuqinile, ukuzwela okukhulu, ukulungiswa okuphezulu kanye nokukhishwa kwedijithali.
