Ukusetshenziswa kwenzwa yokucindezela:
Inzwa yokucindezela ingashintsha ngokuqondile ingcindezi elinganisiwe ibe izinhlobo ezihlukahlukene zamasignali kagesi, okulula ukuhlangabezana nezidingo zokutholwa kwendawo eyodwa nokulawulwa kwesistimu ezenzakalelayo, ngakho-ke isetshenziswa kabanzi ekukhiqizeni izimboni.
Izinzwa zokucindezela zisetshenziswa kakhulu ezinhlelweni eziningi zokuqapha nokulawula.Ngokungeziwe ezilinganisweni zengcindezi eqondile, izinzwa zengcindezi zingasetshenziswa futhi ukulinganisa ngokungaqondile ezinye izinto, njengokugeleza koketshezi/igesi, isivinini, ukuphakama kwamanzi noma ukuphakama.
Ngesikhathi esifanayo, kukhona nekilasi lezinzwa zokucindezela eziklanyelwe ukulinganisa ngokuguquguqukayo izinguquko zejubane eliphezulu ekucindezelweni.Izibonelo zezinhlelo zokusebenza ukuqapha ingcindezi yokusha yamasilinda enjini noma ukugada ingcindezi yegesi ezinjinini ze-turbine.Izinzwa ezinjalo ngokuvamile zenziwe ngezinto ze-piezoelectric, njenge-quartz.
Ezinye izinzwa zokucindezela, njengalezo ezisetshenziswa kumakhamera wethrafikhi, zisebenza kumodi kanambambili, okungukuthi, lapho ingcindezi ifinyelela inani elithile, inzwa ilawula ukuthi isifunda sivuliwe noma sivaliwe.Lolu hlobo lwenzwa yokucindezela lubizwa nangokuthi i-pressure switch.
Izicelo eziyinhloko zimi kanje:
1. Kusetshenziswa ohlelweni lwe-hydraulic
Inzwa yokucindezela ohlelweni lwe-hydraulic ikakhulukazi ukuqedela ukulawulwa kwamandla okuvaliwe - loop.Lapho i-spool yokulawula ihamba ngokuzumayo, ingcindezi ephakeme izikhathi eziningana ukucindezela kokusebenza kwesistimu kungakhiwa ngesikhathi esifushane kakhulu.Emishinini yokuhamba evamile kanye nama-hydraulics embonini, noma iyiphi inzwa yokucindezela engadizayinwanga kucatshangwa ngezimo ezimbi kangaka izobhujiswa maduzane.Kuyadingeka ukusebenzisa inzwa yokucindezela engazweli.Kunezindlela ezimbili eziyinhloko zokubona inzwa yengcindezi ekwazi ukumelana nomthelela, enye iwukushintsha uhlobo lwe-chip, kanti enye iyikhoyili yangaphandle.Ngokuvamile, indlela yokuqala isetshenziswa ohlelweni lwe-hydraulic, ikakhulukazi ngoba kulula ukuyifaka.Ngaphezu kwalokho, inzwa yokucindezela kufanele futhi imelane nokucindezela okuqhubekayo kwe-pulsation kusuka kupompo ye-hydraulic.
2, isetshenziswa ohlelweni lokulawula ukuphepha
Inzwa yokucindezela ivame ukusetshenziswa ohlelweni lokulawula ukuphepha, ikakhulukazi emkhakheni wesistimu yokulawula ukuphepha kwe-compressor.Kunezinhlelo zokusebenza eziningi zenzwa emkhakheni wokulawula ukuphepha.Njengenzwa evamile kakhulu, inzwa yokucindezela ayimangazi ekusebenziseni uhlelo lokulawula ukuphepha.
Emkhakheni wokulawula ukuphepha, isicelo ngokuvamile sicatshangelwa kusukela ekusebenzeni, kusukela ngentengo, futhi kusukela ekusebenzeni kwangempela kokuphepha kanye nokulula okufanele kucatshangelwe, okwangempela kufakazele ukuthi ukukhethwa komphumela wenzwa yokucindezela kuhle kakhulu.Inzwa yokucindezela isebenzisa amasu omshini wemishini yokufaka izingxenye kanye nezilawuli zesignali ku-chip encane.Ngakho usayizi omncane ubuye omunye izinzuzo zayo, ngaphezu intengo ishibhile kungenye inzuzo enkulu.Ngokwezinga elithile, ingathuthukisa ukunemba kokuhlolwa kwesistimu.Kuhlelo lokulawula ukuphepha, inzwa yokucindezela ifakwe emishinini yepayipi le-outlet yomoya ukulawula ingcindezi elethwa i-compressor ngezinga elithile, okuyisilinganiso esithile sokuvikela, kodwa futhi uhlelo lokulawula olusebenza kahle kakhulu.Lapho i-compressor iqala ngokujwayelekile, uma inani lokucindezela lingafinyeleli umkhawulo ophezulu, isilawuli sizovula i-air inlet futhi siyilungise ukuze senze imishini ifinyelele amandla amakhulu.
3, esetshenziswa ekubunjweni komjovo
Inzwa yokucindezela idlala indima ebalulekile ekubunjeni komjovo.Inzwa yokucindezela ingafakwa ku-nozzle yomshini wokubumba umjovo, uhlelo lomgijimi oshisayo, uhlelo lomgijimi obandayo kanye nomgodi wokufa wesikhunta.Ingakwazi ukukala ingcindezi yepulasitiki endaweni ethile phakathi kwe-nozzle yomshini wokubumba umjovo kanye nomgodi wokufa ngesikhathi sokujova, ukugcwalisa, ukulondolozwa kwengcindezi nokupholisa.
4, isetshenziswa ekuqapheni ingcindezi yemayini
Kunezinhlobo eziningi zezinzwa zokucindezela, futhi ngokusekelwe endaweni ekhethekile yokuqapha ingcindezi yezimayini, izinzwa zokucindezela kwezimayini ikakhulukazi zifaka: inzwa yokucindezela i-semiconductor piezoresistive, inzwa yokucindezela kwensimbi yensimbi, inzwa yokuhlukanisa i-transformer pressure nokunye.Lezi zinzwa zinezinhlobonhlobo zezicelo embonini yezimayini, ukusetshenziswa okuqondile okumele kukhethwe inzwa ngokuya ngendawo ethile yezimayini.
I-5, esetshenziswa ku-compressor, imishini ebandayo ye-air conditioning
Izinzwa zokucindezela zivame ukusetshenziswa emishinini yokunyathelisa yomoya, kanye nemishini yesiqandisi ye-air conditioning.Lolu hlobo lwemikhiqizo yezinzwa luncane ngokwakheka, kulula ukulufaka, futhi imbobo yokuqondisa ingcindezi ivamise ukuklanywa ngenaliti yevalvu ekhethekile.
