Kugogoda SENSOR. Mfundo ntchito ndi yachinsinsi

magalimoto amakono zili ndi masensa zosiyanasiyana umboni wokwanira kuti ulamuliro wagawo akulamulira ntchito unit lonse. Chimodzi mwa zinthu izi nawo dongosolo la mafuta jekeseni, ndi kachipangizo detonation, mfundo zomwe zachokera zotsatira piezoelectric.

Kugogoda kachipangizo ili injini galimoto. Iwo amapanga nyemba voteji ku detonation mabomba mu injini. Pamaziko a umboni kuwapeza iwo, ulamuliro wagawo akulamulira kundipatsako kwa mafuta, potero kukwaniritsa pazipita injini mphamvu ndi mafuta dzuwa.

Mitundu ya masensa kugogoda

Pali mitundu iwiri ya chipangizo - burodibandi ndi resonant. Koma tsopano kachipangizo kumveka kugogoda si zoyenera monga muyezo. Muyenera kudziwa kuti sakugwira ntchito mosinthana kwambiri moti Mwachitsanzo, mmalo mwa burodibandi resonant sizigwira ntchito.

Mfundo ntchito

ntchito kachipangizo zachokera zotsatira piezoelectric. Mtsogoleri akutumiza kachipangizo chizindikiro kuchokera DC voteji wa 5V. Ndi resistor, omwe amachepetsa voteji kuti 2.5V, ndi kubwerera kwa Mtsogoleri AC chizindikiro. n'zosiyana chizindikiro kutengerapo imagwiridwa ndi kupeza kutchulidwa voteji dera. Zimenezi n'zotheka chifukwa Mtsogoleri alandira chizindikiro kuchokera DC voteji, ndipo n'zosiyana - AC voteji. Pamene kuphulika akupezeka injini detonation kachipangizo mbendera ndi kwaiye AC matalikidwe ndi pafupipafupi zomwe mwachindunji amadalira mphamvu detonation. Ngati pa ntchito yachibadwa ya galimoto Mtsogoleri akubwerera ndi AC chizindikiro voteji 2.5V, Mtsogoleri masamba injini ntchito mu mode panopa. Ngati chizindikiro chifukwa ndi kupatuka a mtengo udindo, Mtsogoleri chimasintha ndi poyatsira nthawi, kuzimitsa ndi detonation ndi kutengerapo ntchito injini mu mode ndalama ndi otetezeka.

Afufuze kugogoda kachipangizo

Kunyumba, ndi kugogoda sensa ndi ntchito zake akhoza kufufuzidwa ndi multimeter a. Choyamba, tiyenera sakukhudzidwa cholumikizira ya magetsi, kenako unscrew izo kwa injini. Polumikiza Tester kuti kafukufuku motere: chofiira (zabwino) waya chikugwirizana ndi kukhudzana mu cholumikizira, ndi wakuda (zoipa) - nyumba ya. Kuyesa Mwachangu zofunika mopepuka dinani ulusi, umene ndi kachipangizo kugogoda uyenera nyemba wa ku 300 MV voteji, amene akaundula a multimeter. Ngati kukakhala mphamvu si anawawerenga, ndiye sensa ndi olakwika. Ngati multimeter voteji limagwira nthawi iliyonse sitiroko, fufuzani kachipangizo cholumikizira ndi mawaya. Nthawi zambiri ndi mu kukhudzana zoipa palibe Mtsogoleri kulankhulana ndi sensa, kotero muyenera kuyeretsa kulankhula ndi. Komanso fufuzani Kulumikizana kwa dera lotseguka. N'zotheka kuti chingwe ndi likusokonekera chabe, penapake kapena kusiya.
