Kwiimoto zanamhlanje, iitrektara kunye nezinye izixhobo, iinkqubo ezahlukeneyo ze-hydraulic zisetyenziswa ngokubanzi.Indima ebalulekileyo ekusebenzeni kwezi nkqubo idlalwa ngama-alamu-hydraulic alarms - funda konke malunga nezi zixhobo, iintlobo zazo ezikhoyo, ukuyila kunye nokusebenza, kunye nokukhethwa kunye nokutshintshwa kwezinzwa, kwinqaku.
Yintoni i-alam ye-hydraulic sensor?
Isixhobo se-Sensor-hydrosignaling (i-sensor-relay, i-sensor-indicator yenqanaba le-liquid) - into yokulawula i-electronic, ukubeka iliso kunye neenkqubo zokubonisa iinkqubo ze-hydraulic zezithuthi;Isivamvo se-threshold esithumela isignali kwisalathisi okanye kwi-activator (s) xa ulwelo lufikelela kumphakamo omiswe kwangaphambili.
Kuyo nayiphi na isithuthi kukho iinkqubo ezininzi ze-hydraulic kunye namacandelo: iinkqubo zombane zamanzi (kwiilori, iitrektara kunye nezixhobo ezahlukeneyo), iinkqubo zokuthambisa kunye nokupholisa iyunithi yamandla, inkqubo yokubonelela ngombane, i-washers yefestile, i-power steering kunye nabanye.Kwezinye iinkqubo, umgangatho we-liquid kufuneka ubekwe esweni rhoqo (njengakwitanki yamafutha), ngelixa kwezinye kuyimfuneko kuphela ukufumana ulwazi malunga nobukho okanye ukungabikho kolwelo, okanye malunga nolwelo olugqithisayo kwinqanaba elithile (ukugqithisa okanye ukuwa) .Umsebenzi wokuqala uxazululwa ngamava amanqanaba aqhubekayo, kwaye okwesibini, i-hydraulic alarm sensors (DGS) okanye i-liquid level sensors isetyenziswa.
I-DGS ifakwe kwiitanki zokwandisa, i-crankcase ye-injini kunye nezinye izinto ze-hydraulic systems.Xa i-liquid ifikelela kwinqanaba elithile, inzwa iyashukunyiswa, ivala okanye ivule isiphaluka, inika isalathisi sokuvula / ukuvala kwideshibhodi (umzekelo, isalathisi sokulahla ioli), okanye ukucima / ukucima i-actuator - iimpompo, iidrives kunye ne-oyile. ezinye ezibonelela ngotshintsho kwinqanaba lolwelo okanye utshintsho kwindlela yokusebenza yenkqubo yonke yehydraulic.Yiyo loo nto i-DGS idla ngokubizwa ngokuba zii-sensor-signaling devices kunye ne-sensor-relays.
Kwizixhobo zemoto zanamhlanje, iindidi ezininzi ze-alamu-hydraulic alarms zisetyenziswa - kufuneka zichazwe ngokubanzi.
Iindidi kunye neempawu ze-hydraulic alarm sensors
Iinzwa zanamhlanje zihlulwe zibe ziintlobo ezininzi ngokomgaqo womzimba wokusebenza, indawo yokusebenza (uhlobo lolwelo) kunye neempawu zayo, indawo eqhelekileyo yabafowunelwa, indlela yokudibanisa kunye neempawu zombane.
Ngokomgaqo womzimba wokusebenza, ii-DGS zeemoto zahlulwe zibe ngamaqela amabini:
● i-conductometric;
● Ukudada.
I-Conductometric sensors ziyilelwe ukusebenza ngolwelo olusebenza ngombane (ingakumbi amanzi kunye nezipholileyo).Ezi DGS zilinganisa ukuchasana kombane phakathi komqondiso kunye ne-electrodes eqhelekileyo (umhlaba), kwaye xa ukuchasana kwehla ngokukhawuleza, kuthumela umqondiso kwisalathisi okanye i-actuator.I-sensor conductivity iqulethe i-probe yensimbi (edla ngokwenziwa ngetsimbi engenasici) kunye nesekethe ye-elektroniki (ibandakanya i-pulse generator kunye ne-amplifier yomqondiso).I-probe yenza imisebenzi ye-electrode yokuqala, imisebenzi ye-electrode yesibini ibelwa kwisitya ngokwayo kunye nolwelo (ukuba sisinyithi) okanye intambo yentsimbi ebekwe ecaleni kwezantsi okanye iindonga zesitya.I-sensor ye-conductometric isebenza ngokulula: xa inqanaba le-liquid lingaphantsi kwe-probe, ukuchasana kombane kudla ngokungapheliyo - akukho mqondiso kwi-output ye-sensor, okanye kukho umqondiso malunga nomgangatho ophantsi wamanzi;Xa i-liquid ifikelela kwi-sensor probe, ukuchasana kwehla ngokukhawuleza (i-liquid iqhuba ngoku) - kwi-output ye-sensor, isignali iyatshintsha ngokuchaseneyo.
Izinzwa ze-Float zingasebenza kunye naluphi na uhlobo lolwelo, zombini i-conductor kunye ne-non-conductive.Isiseko senzwa enjalo yi-float yoyilo oluthile oluhambelana neqela loqhagamshelwano.I-sensor ibekwe kwinqanaba lomda apho umbane unokufikelela ngexesha lokusebenza ngokuqhelekileyo kwenkqubo, kwaye xa i-liquid ifikelela kweli nqanaba, ithumela uphawu kwisalathisi okanye i-actuator.
Kukho iindidi ezimbini eziphambili zezivamvo zokudada:
● Ngefloti eqhagamshelwe kuqhagamshelwano olushukumayo lweqela loqhagamshelwano;
● Ngokudada ngemagnethi kunye nokutshintsha ingcongolo.
I-DGS yohlobo lokuqala yizona zilula kuyilo: zisekelwe kwi-float ngendlela ye-probe yeplastiki okanye i-cylinder yobhedu engenanto edityaniswe kuqhagamshelwano oluhambayo lweqela loqhagamshelwano.Xa inqanaba le-liquid likhuphuka, i-float iphakama kwaye kwinqanaba elithile kukho isiphaluka esifutshane okanye, ngokuchaseneyo, ukuvulwa kwabafowunelwa.
Izivamvo zodidi lwesibini zinoyilo oluntsonkothileyo ngakumbi: zisekwe kwintonga enomgongxo kunye neswitshi yengcongolo (iswitshi yamagnetic) ebekwe ngaphakathi, ecaleni kwe-axis apho i-annular float enemagnethi esisigxina inokuhamba.Utshintsho kwinqanaba lolwelo lubangela ukuba i-float ihambe ecaleni kwe-axis, kwaye xa umazibuthe edlula kwiswitshi yengcongolo, abafowunelwa bayo bavaliwe okanye bavulwe.
Ngokohlobo lwendawo yokusebenza, ii-alamu ze-automotive-hydraulic alarms zahlulwe zaba ziindidi ezine eziphambili:
● Eyokusebenza emanzini;
● Umsebenzi kwi-antifreeze;
● Eyomsebenzi kwioli;
● Ukusebenza kwipetroli (ipetroli okanye idizili).

Umzobo wenzwa yengcongolo enemagnethi edadayo
I-DGS yemidiya eyahlukeneyo iyahluka kwizinto ezisetyenzisiweyo, kwaye abenzi boluvo be-float nabo bahluke kubukhulu bezinto ezidadayo ukunika ukuphakama okwaneleyo kwiindawo ezixinana ezahlukeneyo.
Ngokwendawo eqhelekileyo yabafowunelwa, abenzi boluvo bahlulwe bangamaqela amabini:
● Ngabafowunelwa abavulwa ngokuqhelekileyo;
● Ngabafowunelwa abaqhele ukuvalwa.
Ii-Sensors zinokuba neendlela ezahlukeneyo zokudibanisa kwinkqubo yombane: izixhumi ezikude kunye neefowuni zokudibanisa, iziqhagamshelo ezidibeneyo kunye neefowuni zokudibanisa kunye ne-bayonet-type connectors.Ngokuqhelekileyo, i-DGS yeemoto inezikhonkwane ezine: ezimbini zonikezelo lwamandla ("plus" kunye ne "minus"), umqondiso omnye kunye nokulinganisa omnye.
Kwiimpawu eziphambili zeesensi zoluvo, kuyafuneka ukuba kuqaqambise amandla ombane (12 okanye 24 V), ixesha lokulibaziseka lokuphendula (ukusuka ekusebenzeni kwangoko ukuya ekulibazisekeni kwemizuzwana embalwa), ubushushu bokusebenza, ukusetyenziswa kwangoku, intambo yokunyuka kunye nobukhulu be-hexagon ye-turnkey.
Uyilo kunye neempawu ze-automotive sensors-hydraulic signaling devices
Zonke ii-DGS zeemoto zanamhlanje zinoyilo olufanayo.Zisekelwe kwityala lobhedu, ngaphandle apho kukho intambo kunye ne-hexagon ye-turnkey.Ngaphakathi kwimeko kukho into yokuva (i-float probe okanye iprobe yensimbi), iqela loqhagamshelwano kunye nebhodi ene-amplifier / generator circuit.Phezulu kwi-sensor kukho umdibaniso wombane okanye intambo yocingo kunye nekhonkco ekupheleni.
Inzwa ifakwe kwitanki okanye enye into yenkqubo ye-hydraulic isebenzisa intambo nge-O-ring (gasket).Ngoncedo lwekhonkco, inzwa ixhunyiwe kwinkqubo yombane yesithuthi.
Isithuthi sinokuba ne-5 okanye ngaphezulu i-alamu ye-hydraulic alarms eyenza imisebenzi yokubeka iliso kwinqanaba le-fuel, i-coolant, i-oyile kwi-injini, i-fluid kwi-hydraulic system, i-fluid kwi-power steering, njl.
Indlela yokukhetha kunye nokubuyisela i-alamu ye-sensor-hydraulic alarm
Izinzwa zomgangatho wolwelozibalulekile ekusebenzeni okuqhelekileyo kweenkqubo zomntu ngamnye kunye nesithuthi siphela.Iimpawu ezahlukeneyo zibonisa ukuchithwa kwe-DGS - ii-alamu zobuxoki zezibonakaliso okanye i-actuators (ukucima okanye ukucima iimpompo, njl.), Okanye, ngokuchaseneyo, ukungabikho komqondiso kwisalathisi okanye i-actuators.Ukuze ugweme ukungasebenzi kakubi, inzwa kufuneka itshintshwe ngokukhawuleza.
Ukutshintshwa, kuyimfuneko ukuthatha izinzwa kuphela kwezo ntlobo kunye neemodeli ezicetyiswa ngumenzi wemoto.I-DGS kufuneka ibe nemilinganiselo ethile kunye neempawu zombane, xa ufaka inzwa yolunye uhlobo, inkqubo inokusebenza kakubi.Inzwa iyatshintshwa ngokwemiyalelo yokulungisa isithuthi.Ngokwesiqhelo, lo msebenzi wehla ukukhubaza inzwa, uyikhuphe ngesitshixo, kwaye ufake inzwa entsha.Qinisekisa ukuba uhlambulule indawo yokufakela inzwa ekungcoleni, kwaye usebenzise i-O-ring (ngokuqhelekileyo ifakiwe) ngexesha lofakelo.Kwezinye iimeko, kunokuba yimfuneko ukukhupha ulwelo kwisixhobo.
Ii-alam ze-Sensors-hydraulic
Emva kokufakela, ezinye iinzwa zifuna ukulinganisa, inkqubo echazwe kwimiyalelo efanelekileyo.
Ngokukhetha okuchanekileyo kunye nokutshintshwa kwe-alamu ye-sensor-hydraulic alarm, nayiphi na inkqubo ehambelana nayo iya kusebenza ngokuqhelekileyo, iqinisekisa ukusebenza okuthembekileyo nokukhuselekileyo kwesithuthi.
