M'magalimoto amakono, mathirakitala ndi zida zina, machitidwe osiyanasiyana a hydraulic amagwiritsidwa ntchito kwambiri.Udindo wofunikira pakugwira ntchito kwa machitidwewa umaseweredwa ndi masensa-hydraulic alarm - werengani zonse za zida izi, mitundu yawo yomwe ilipo, mapangidwe ndi magwiridwe antchito, komanso kusankha ndikusintha masensa, m'nkhaniyi.
Kodi hydraulic alarm sensor ndi chiyani?
Sensor-hydrosignaling device (sensor-relay, sensor-indicator of fluid level) - chinthu chamagetsi, kuyang'anira ndikuwonetsa machitidwe a hydraulic system;Sensa ya pachimake yomwe imatumiza chizindikiro ku cholozera kapena chowongolera pamene madziwo afika pamlingo wokonzedweratu.
Mu galimoto iliyonse pali machitidwe angapo hayidiroliki ndi zigawo zikuluzikulu: mphamvu hayidiroliki kachitidwe (magalimoto, mathirakitala ndi zipangizo zosiyanasiyana), mafuta ndi kuzirala kachitidwe wagawo mphamvu, dongosolo magetsi, ochapira zenera, chiwongolero mphamvu ndi ena.M'makina ena, mulingo wamadzimadzi uyenera kuyang'aniridwa nthawi zonse (monga mu tanki yamafuta), pomwe ena amangofunika kudziwa za kukhalapo kapena kusakhalapo kwamadzimadzi, kapena zamadzimadzi zomwe zimapambana mulingo wina (kupitilira kapena kugwa) .Ntchito yoyamba imathetsedwa ndi masensa osalekeza, ndipo chachiwiri, ma hydraulic alarm sensors (DGS) kapena masensa amadzimadzi amagwiritsidwa ntchito.
DGS amayikidwa mu akasinja kukula, injini crankcase ndi zinthu zina za makina hayidiroliki.Madzi akafika pamlingo wina, sensa imayambika, imatseka kapena kutsegulira dera, kupereka chizindikiro cha / off pa dashboard (mwachitsanzo, chizindikiro chotsitsa mafuta), kapena kuyatsa / kuzimitsa ma actuators - mapampu, ma drive ndi zina zomwe zimapereka kusintha kwa mlingo wamadzimadzi kapena kusintha kwa machitidwe a hydraulic system yonse.Ichi ndichifukwa chake DGS nthawi zambiri imatchedwa zida zowonetsera masensa ndi ma sensor-relays.
Pazida zamakono zamagalimoto, ma alamu osiyanasiyana a masensa-hydraulic amagwiritsidwa ntchito - ayenera kufotokozedwa mwatsatanetsatane.
Mitundu ndi mawonekedwe a hydraulic alarm sensors
Masensa amasiku ano amagawidwa m'mitundu ingapo malinga ndi momwe thupi limagwirira ntchito, malo ogwirira ntchito (mtundu wamadzimadzi) ndi mawonekedwe ake, malo omwe amalumikizana nawo, njira yolumikizirana komanso mawonekedwe amagetsi.
Malinga ndi mfundo zakuthupi zogwirira ntchito, magalimoto a DGS amagawidwa m'magulu awiri:
● conductometric;
● Kuyandama.
Masensa a Conductometric adapangidwa kuti azigwira ntchito ndi zakumwa zamagetsi (makamaka madzi ndi zoziziritsa kukhosi).Ma DGS awa amayezera kukana kwamagetsi pakati pa chizindikiro ndi ma electrode wamba (pansi), ndipo kukana kutsika kwambiri, kumatumiza chizindikiro kwa chizindikiro kapena actuator.Sensa ya conductivity imakhala ndi kafukufuku wachitsulo (kawirikawiri wopangidwa ndi chitsulo chosapanga dzimbiri) ndi dera lamagetsi (amaphatikizapo pulse jenereta ndi amplifier chizindikiro).Kufufuza kumagwira ntchito za electrode yoyamba, ntchito za electrode yachiwiri zimaperekedwa ku chidebe chokhachokha ndi madzi (ngati ndi chitsulo) kapena chingwe chachitsulo choyikidwa pansi kapena makoma a chidebecho.Sensa ya conductometric imagwira ntchito mophweka: pamene mlingo wamadzimadzi uli pansi pa kafukufuku, kukana kwa magetsi kumakhala kosalekeza - palibe chizindikiro pa kutuluka kwa sensa, kapena pali chizindikiro cha mlingo wochepa wamadzimadzi;Madzi akafika pa kafukufuku wa sensa, kukana kumatsika kwambiri (madzi amadzimadzi amadzimadzimadzi) - pakutulutsa kwa sensa, chizindikirocho chimasintha mosiyana.
Masensa akuyandama amatha kugwira ntchito ndi mtundu uliwonse wamadzimadzi, oyendetsa komanso osayendetsa.Maziko a sensa yotere ndi kuyandama kwa mapangidwe enaake okhudzana ndi gulu lolumikizana.Sensa ili pamlingo wa malire omwe madzi amatha kufika panthawi yogwira ntchito bwino, ndipo madziwo akafika pamlingo uwu, amatumiza chizindikiro kwa chizindikiro kapena actuator.
Pali mitundu iwiri ikuluikulu ya masensa oyandama:
● Ndi choyandama cholumikizidwa ndi kukhudzana kosunthika kwa gulu lolumikizana;
● Ndi maginito zoyandama ndi bango lophimba.
Ma DGS amtundu woyamba ndi osavuta kwambiri pamapangidwe: amakhazikika pa choyandama mu mawonekedwe a kafukufuku wapulasitiki kapena silinda yamkuwa yopanda kanthu yolumikizidwa ndi kukhudzana kosunthika kwa gulu lolumikizana.Pamene mlingo wamadzimadzi umakwera, choyandamacho chimakwera ndipo panthawi inayake pali dera laling'ono kapena, mosiyana, kutsegula kwa ojambula.
Zomverera zamtundu wachiwiri zimakhala ndi mapangidwe ovuta kwambiri: zimakhazikitsidwa ndi ndodo yopanda kanthu yokhala ndi bango losinthira (maginito maginito) yomwe ili mkati, motsatira njira yomwe kuyandama kwa annular ndi maginito okhazikika kumatha kusuntha.Kusintha kwa mulingo wamadzimadzi kumapangitsa kuti zoyandama zisunthike motsatira nsonga, ndipo maginito ikadutsa pa bango losinthira, zolumikizira zake zimatsekedwa kapena kutsegulidwa.
Malinga ndi mtundu wa malo ogwirira ntchito, ma alarm amagetsi-hydraulic ma alarm amagawidwa m'magulu anayi:
● Ntchito m'madzi;
● Ntchito mu antifreeze;
● Ntchito mu mafuta;
● Kugwira ntchito mumafuta (petulo kapena dizilo).
Sensor-hydraulic detector yokhala ndi probe yachitsulo
Chithunzi cha sensa yoyandama yokhala ndi cholumikizira chosunthika
Chithunzi cha sensa ya bango yokhala ndi maginito oyandama
DGS yama media osiyanasiyana amasiyana ndi zida zomwe zimagwiritsidwa ntchito, ndipo zowunikira zoyandama zimasiyananso kukula kwa zoyandama kuti zipereke kukweza kokwanira m'malo osiyanasiyana.
Malinga ndi malo omwe amalumikizana nawo, masensa amagawidwa m'magulu awiri:
● Ndi omwe amatsegula nthawi zambiri;
● Ndi anzanu omwe nthawi zambiri amatsekedwa.
Zomverera zimatha kukhala ndi njira zosiyanasiyana zolumikizirana ndi magetsi: zolumikizira zakutali zolumikizana ndi mpeni, zolumikizira zophatikizika ndi mipeni ndi zolumikizira zamtundu wa bayonet.Childs, magalimoto DGS ndi zikhomo zinayi: awiri kwa magetsi ("kuphatikiza" ndi "opanda"), chizindikiro chimodzi ndi calibration mmodzi.
Mwa mawonekedwe akuluakulu a masensa, ndikofunikira kuunikira magetsi operekera (12 kapena 24 V), nthawi yochedwa kuyankha (kuchokera pakugwira ntchito nthawi yomweyo mpaka kuchedwa kwa masekondi angapo), kuchuluka kwa kutentha kwa ntchito, kugwiritsa ntchito pano, ulusi wokwera ndi kukula kwa hexagon ya turnkey.
Mapangidwe ndi mawonekedwe a zida zamagalimoto zamasensa-hydraulic signing
Ma DGS onse amakono amagalimoto ali ndi mapangidwe ofanana.Zimachokera pazitsulo zamkuwa, kunja kwake komwe kuli ulusi ndi hexagon ya turnkey.Mkati mwake muli chinthu chomverera (zoyandama probe kapena chitsulo probe), gulu lolumikizana ndi bolodi yokhala ndi amplifier / jenereta dera.Pamwamba pa sensa ndi cholumikizira magetsi kapena chingwe cholumikizira cholumikizira kumapeto.
Sensa imayikidwa mu thanki kapena chinthu china cha hydraulic system pogwiritsa ntchito ulusi kudzera mu O-ring (gasket).Mothandizidwa ndi cholumikizira, sensor imalumikizidwa kumagetsi agalimoto.
Galimoto imatha kukhala ndi masensa asanu kapena kupitilira apo - ma alarm a hydraulic omwe amagwira ntchito zowunika kuchuluka kwamafuta, zoziziritsa kukhosi, mafuta mu injini, madzimadzi mu hydraulic system, madzimadzi mu chiwongolero chamagetsi, ndi zina zambiri.
Momwe mungasankhire ndikusintha alamu ya sensor-hydraulic
Sensa zamadzimadzindi zofunika kuti yachibadwa kachitidwe munthu ndi galimoto lonse.Zizindikiro zosiyanasiyana zimasonyeza kuwonongeka kwa DGS - machenjezo onyenga a zizindikiro kapena ma actuators (kuyatsa kapena kutseka mapampu, etc.), kapena, mosiyana, kusowa kwa chizindikiro pa chizindikiro kapena actuators.Kuti mupewe zovuta zazikulu, sensor iyenera kusinthidwa posachedwa.
Kuti mulowe m'malo, ndikofunikira kutenga masensa okha amitundu ndi zitsanzo zomwe zimalimbikitsidwa ndi automaker.DGS iyenera kukhala ndi miyeso ina ndi mawonekedwe amagetsi, pakuyika sensa yamtundu wina, dongosololi likhoza kulephera.Sensa imasinthidwa malinga ndi malangizo okonza galimoto.Nthawi zambiri, ntchitoyi imatsikira kuletsa sensa, kuyitulutsa ndi kiyi, ndikuyika sensor yatsopano.Onetsetsani kuti mukuyeretsa malo oyika sensa kuchokera ku dothi, ndikugwiritsa ntchito mphete ya O (yomwe nthawi zambiri imaphatikizidwa) pakuyika.Nthawi zina, pangafunike kukhetsa madzi kuchokera pa chipangizocho.
Zomverera - hydraulic alarm
Pambuyo unsembe, masensa ena amafuna calibration, ndondomeko amene akufotokozedwa malangizo oyenerera.
Ndi kusankha koyenera ndikusintha alamu ya sensor-hydraulic alarm, dongosolo lililonse logwirizana nalo lidzagwira ntchito moyenera, kuonetsetsa kuti galimotoyo ikuyenda modalirika komanso yotetezeka.
