Ezimotweni zanamuhla, ogandaganda nezinye izinto zokusebenza, amasistimu ahlukahlukene we-hydraulic asetshenziswa kabanzi.Indima ebalulekile ekusebenzeni kwalezi zinhlelo idlalwe yizinzwa-ama-alamu we-hydraulic - funda konke mayelana nalawa madivayisi, izinhlobo zawo ezikhona, ukuklama nokusebenza, kanye nokukhetha nokushintshwa kwezinzwa, esihlokweni.
Iyini inzwa ye-alamu ye-hydraulic?
I-sensor-hydrosignaling device (i-sensor-relay, inzwa-inkomba yezinga le-liquid) - isici sokulawula i-electronic, ukuqapha kanye nezinhlelo zezinkomba zezinhlelo ze-hydraulic zezimoto;Inzwa ye-threshold ethumela isignali kusibonisi noma i-actuator lapho uketshezi lufinyelela ileveli enqunyiwe ngaphambili.
Kunoma iyiphi imoto kunezinhlelo eziningana ze-hydraulic kanye nezingxenye: izinhlelo zamandla we-hydraulic (kumaloli, ogandaganda kanye nemishini ehlukahlukene), amasistimu wokuthambisa kanye nokupholisa weyunithi yamandla, uhlelo lokuphakela amandla, amawasha amafasitela, isiteringi sikagesi nokunye.Kwezinye izinhlelo, izinga le-liquid kufanele liqashwe njalo (njengasethangini likaphethiloli), kanti kwezinye kudingekile kuphela ukuthola ulwazi mayelana nokuba khona noma ukungabi khona koketshezi, noma mayelana noketshezi olunqoba izinga elithile (olwedlulayo noma oluwayo) .Umsebenzi wokuqala uxazululwa yizinzwa zezinga eliqhubekayo, kanti okwesibili, kusetshenziswa izinzwa ze-hydraulic alarm (DGS) noma izinzwa zezinga le-liquid.
I-DGS ifakwe emathangini okunweba, i-crankcase yenjini kanye nezinye izakhi zamasistimu we-hydraulic.Lapho uketshezi lufika ezingeni elithile, inzwa iyacushwa, ivale noma ivule isekethe, inikeze inkomba yokuvula/yokuvala kudeshibhodi (isibonelo, inkomba yokulahla uwoyela), noma ukuvula/ukuvala ama-actuator - amaphampu, amadrayivu kanye ezinye ezihlinzeka ngoshintsho ezingeni le-liquid noma ushintsho kumodi yokusebenza yalo lonke uhlelo lwe-hydraulic.Yingakho i-DGS ivame ukubizwa ngokuthi amadivaysi ama-sensor-signaling nama-sensor-relays.
Emishinini yesimanje yezimoto, kusetshenziswe ama-alamu ahlukahlukene wezinzwa-hydraulic - kufanele achazwe kabanzi.
Izinhlobo nezici zezinzwa ze-alamu ze-hydraulic
Izinzwa zanamuhla zihlukaniswe zibe izinhlobo eziningana ngokuvumelana nesimiso somzimba sokusebenza, indawo yokusebenza (uhlobo loketshezi) nezici zalo, isikhundla esivamile soxhumana nabo, indlela yokuxhuma kanye nezici zikagesi.
Ngokwesimiso somzimba sokusebenza, i-DGS yezimoto ihlukaniswe ngamaqembu amabili:
● i-conductometric;
● Nntanta.
Izinzwa ze-Conductometric zenzelwe ukusebenza ngoketshezi olusebenza ngogesi (ikakhulukazi amanzi nezipholile).Lawa ma-DGS akala ukumelana nogesi phakathi kwesiginali nama-electrode avamile (aphansi), futhi lapho ukumelana kwehla kakhulu, ithumela isignali kusibonisi noma ku-actuator.Inzwa ye-conductivity iqukethe i-probe yensimbi (evame ukwenziwa ngensimbi engagqwali) kanye nesekhethi ye-electronic (ihlanganisa i-pulse generator kanye ne-amplifier yesignali).I-probe yenza imisebenzi ye-electrode yokuqala, imisebenzi ye-electrode yesibili inikezwa esitsheni ngokwaso ngoketshezi (uma kuyinsimbi) noma umugqa wensimbi obekwe phansi noma izindonga zesitsha.Inzwa ye-conductometric isebenza kalula: lapho izinga le-liquid lingaphansi kwe-probe, ukumelana nogesi kuvame ukungapheli - asikho isignali ekuphumeni kwenzwa, noma kukhona isignali mayelana nezinga eliphansi le-liquid;Lapho uketshezi lufinyelela ku-sensor probe, ukumelana kwehla kakhulu (uketshezi luqhuba okwamanje) - ekuphumeni kwenzwa, isignali ishintsha ngokuphambene.
Izinzwa ze-Float zingasebenza nanoma yiluphi uhlobo loketshezi, kokubili okuguquguqukayo nokungaqhubeki.Isisekelo senzwa enjalo yi-float yomklamo othile ohlotshaniswa neqembu lokuxhumana.Inzwa itholakala ezingeni lomkhawulo lapho uketshezi olungafinyelela khona ngesikhathi sokusebenza okuvamile kwesistimu, futhi lapho uketshezi lufinyelela kuleli zinga, luthumela isignali kunkomba noma ku-actuator.
Kunezinhlobo ezimbili eziyinhloko zezinzwa ezintantayo:
● Nge-float exhunywe kothintana naye ohambayo weqembu lokuxhumana;
● Nge-float kazibuthe kanye neswishi yomhlanga.
I-DGS yohlobo lokuqala ilula kakhulu ekwakhiweni: isekelwe ku-float ngendlela ye-plastic probe noma isilinda sethusi esingenalutho esixhunywe kothintana naye othintekayo weqembu lokuxhumana.Lapho izinga le-liquid likhuphuka, i-float iphakama futhi endaweni ethile kukhona isifunda esifushane noma, ngokuphambene, ukuvulwa koxhumana nabo.
Izinzwa zohlobo lwesibili zinomklamo oyinkimbinkimbi kakhudlwana: zisekelwe phezu kwenduku engenalutho enomshini womhlanga (i-switch magnetic) etholakala ngaphakathi, eduze kwe-axis lapho i-annular float enozibuthe unomphela ingahamba.Ukushintsha kwezinga le-liquid kubangela ukuthi iflothi ihambe eduze kwe-eksisi, futhi uma uzibuthe edlula emshinini womhlanga, othintana nabo bayavalwa noma bavuleke.
Ngokusho kohlobo lwendawo yokusebenza, ama-alamu e-automotive sensors-hydraulic ahlukaniswe abe izinhlobo ezine eziyinhloko:
● Okokusebenza emanzini;
● Okokusebenza ku-antifreeze;
● Okokusebenza emafutheni;
● Ngokusebenza kuphethiloli (uphethiloli noma udizili).
I-sensor-hydraulic detector ene-probe yensimbi
Umdwebo wenzwa yokuntanta onokuxhumana okunyakazayo
Umdwebo wenzwa yomhlanga ene-float kazibuthe
I-DGS yemidiya ehlukene iyahluka ezintweni ezisetshenziswayo, futhi izinzwa zokuntanta nazo ziyahluka ngosayizi wezinto ezintantayo ukuze zinikeze ukuphakama okwanele ezindaweni zokuminyana okuhlukile.
Ngokwesimo esijwayelekile soxhumana nabo, izinzwa zihlukaniswe ngamaqembu amabili:
● Ngoxhumana nabo abavame ukuvuleka;
● Ngabathintwayo abavamise ukuvaleka.
Izinzwa zingaba nezindlela ezihlukene zokuxhuma ohlelweni lukagesi: izixhumi ezikude ezinokuxhumana kommese, izixhumi ezihlanganisiwe ezinokuxhumana kommese nezixhumi ezihlanganisiwe zohlobo lwe-bayonet.Ngokuvamile, i-DGS yezimoto inamaphini amane: amabili okunikezwa kwamandla ("plus" kanye "nokususa"), isignali eyodwa kanye nokulinganisa okukodwa.
Ezicini eziyinhloko zezinzwa, kuyadingeka ukugqamisa i-voltage yokuhlinzeka (12 noma 24 V), isikhathi sokubambezeleka kokuphendula (kusuka ekusebenzeni ngokushesha kuya ekubambezelekeni kwemizuzwana embalwa), ibanga lokushisa lokusebenza, ukusetshenziswa kwamanje, intambo ekhwezayo kanye nosayizi wehexagon ye-turnkey.
Idizayini nezici zezinzwa zezimoto-imishini yokubonisa i-hydraulic
Yonke i-DGS yezimoto yesimanje inomklamo ofanayo.Zisekelwe phezu kwekesi lethusi, ngaphandle lapho kukhona intambo kanye ne-hexagon ye-turnkey.Ngaphakathi kwecala kunesici sokuzwa (i-float probe noma i-probe yensimbi), iqembu lokuxhumana kanye nebhodi eline-amplifier / generator circuit.Phezulu kwenzwa kukhona isixhumi sikagesi noma ihhanisi lezintambo elinesixhumi ekugcineni.
Inzwa ifakwe ethangini noma kwenye ingxenye yesistimu ye-hydraulic isebenzisa intambo ngokusebenzisa i-O-ring (gasket).Ngosizo lwesixhumi, inzwa ixhunywe kusistimu kagesi yemoto.
Imoto ingaba nezinzwa ezinhlanu noma ngaphezulu-ama-alamu acindezelayo enza imisebenzi yokuqapha izinga likaphethiloli, isipholile, uwoyela enjinini, uketshezi kusistimu ye-hydraulic, uketshezi esiteringini samandla, njll.
Ungakhetha kanjani futhi ufake esikhundleni i-alamu ye-sensor-hydraulic
Izinzwa zeleveli yoketshezizibalulekile ekusebenzeni okujwayelekile kwezinhlelo zomuntu ngamunye kanye nemoto iyonke.Izimpawu ezahlukahlukene zibonisa ukuwohloka kwe-DGS - ama-alamu angamanga wezinkomba noma ama-actuator (ukukhanyisa noma ukuvala amaphampu, njll.), noma, ngokuphambene, ukungabikho kwesignali kunkomba noma ama-actuator.Ukuze ugweme ukungasebenzi kahle, inzwa kufanele ishintshwe ngokushesha ngangokunokwenzeka.
Ukuze kufakwe esikhundleni, kuyadingeka ukuthatha izinzwa kuphela zalezo zinhlobo namamodeli anconywe i-automaker.I-DGS kufanele ibe nobukhulu obuthile nezici zikagesi, lapho ufaka inzwa yolunye uhlobo, isistimu ingase ingasebenzi kahle.Inzwa iyashintshwa ngokuya ngemiyalelo yokukhanda imoto.Ngokuvamile, lo msebenzi wehlela ekukhubazeni inzwa, ukuyikhipha ngokhiye, nokufaka inzwa entsha.Qinisekisa ukuthi uhlanza indawo yokufaka inzwa ekungcoleni, futhi usebenzise i-O-ring (evame ukufakwa) ngesikhathi sokufakwa.Kwezinye izimo, kungase kudingeke ukukhipha uketshezi kusuka kudivayisi.
Izinzwa-hydraulic alamu
Ngemuva kokufakwa, ezinye izinzwa zidinga ukulinganisa, inqubo echazwe emiyalweni efanele.
Ngokukhetha okulungile nokushintshwa kwe-alamu ye-sensor-hydraulic, noma iyiphi isistimu ehlotshaniswa nayo izosebenza ngokujwayelekile, iqinisekise ukusebenza okuthembekile nokuphephile kwemoto.
