Inzwa yengcindezi yamafutha engu-3083716 ye-Dongfeng motor excavator

Inzwa yokucindezela idivayisi enezici ezizwelayo kumfutho, ekala ingcindezi yegesi noma uketshezi nge-diaphragm eyenziwe ngensimbi engagqwali ne-silicon. Uma usebenzisa inzwa yokucindezela, ezinye izinkinga zizovela nakanjani, njengomsindo. Ubangelwa yini umsindo? Lokhu kungase kube ngenxa yokungaqhubeki kwezinhlayiya ze-conductive zangaphakathi, noma umsindo wokudubula okhiqizwa amadivaysi e-semiconductor. Ezinye izizathu zizochazwa ngokuningiliziwe ngezansi.

Izimbangela zomsindo kunzwa yokucindezela

1. Umsindo we-low-frequency wenzwa yokucindezela ikakhulukazi ubangelwa ukungaqhubeki kwezinhlayiya ze-conductive zangaphakathi. Ikakhulukazi ukumelana nefilimu ye-carbon, kuvame ukuba nezinhlayiya eziningi ezincane ezintweni ze-carbon, futhi izinhlayiya aziqhubeki. Enkambweni yokugeleza kwamanje, ukuqhutshwa kwe-resistor kuzoshintsha, futhi okwamanje kuzoshintsha, okuholela ku-flash arc efana nokuxhumana okubi.

2. Umsindo wezinhlayiyana ezihlakazekile okhiqizwe amadivaysi e-semiconductor ikakhulukazi ngenxa yokushintshwa kwamandla kagesi endaweni yokuvimbela kuzo zombili iziphetho ze-semiconductor PN junction, okuholela ekushintsheni kwenkokhelo enqwabelene kulesi sifunda, ngaleyo ndlela kubonise ithonya amandla. Lapho i-voltage eqondile iyancipha, isifunda sokunciphisa ama-electron nezimbobo siyakhula, okulingana nokukhishwa kwe-capacitor.

3. Uma i-voltage e-reverse isetshenziswa, isifunda sokunciphisa sishintsha ngokuphambene. Lapho i-current igeleza esifundeni esivimbelayo, lolu shintsho luzobangela ukuthi lwamanje olugeleza endaweni yokuvimbela luguquguquke kancane, ngaleyo ndlela lukhiqize umsindo wamanje. Ngokuvamile, ezingxenyeni zikazibuthe ebhodini lesifunda senzwa yokucindezela, uma kukhona ukuphazamiseka, amabhodi amaningi wesekethe anezakhi zikagesi ezifana namareyi namakhoyili. Enqubweni yokugeleza kwamanje okuzinzile, i-inductance yekhoyili namandla asabalalisiwe egobolondo kukhipha amandla endaweni. Amandla azophazamisa amasekhethi aseduze.

4. Sebenza ngokuphindaphindiwe njengama-relay nezinye izingxenye. Ukukhanyisa nokucisha amandla kuzokhiqiza amandla kagesi aphezulu ahlehla ngokushesha kanye namandla okwanda okusheshayo. Le voltage ephezulu esheshayo izoba nomthelela omkhulu kusekethe, okuzophazamisa kakhulu umsebenzi ojwayelekile wokuphakelwa kwamandla. Isekhethi.
