Mumotokari dzemazuva ano, matirakita uye zvimwe midziyo, akasiyana hydraulic masisitimu anoshandiswa zvakanyanya.Basa rakakosha mukushanda kweaya masisitimu rinoitwa nema sensors-hydraulic alarms - verenga zvese nezvemidziyo iyi, mhando dzadzo dziripo, dhizaini nekushanda, pamwe nekusarudzwa nekutsiviwa kwema sensors, mune chinyorwa.
Chii chinonzi hydraulic alarm sensor?
Sensor-hydrosignaling device (sensor-relay, sensor-indicator yezinga remvura) - chinhu chekutonga kwemagetsi, kutarisa uye zviratidzo zve hydraulic systems yemotokari;Chikumbaridzo sensor inotumira chiratidzo kune chiratidzo kana actuator (s) kana mvura yasvika padanho rakafanotemerwa.
Mune chero mota kune akati wandei ma hydraulic masisitimu uye zvikamu: simba hydraulic masisitimu (mumarori, matirakita uye akasiyana midziyo), lubrication uye kutonhora masisitimu eiyo magetsi unit, magetsi emagetsi system, washer mahwindo, magetsi ekufambisa uye nezvimwe.Mune mamwe masisitimu, iyo nhanho yemvura inofanirwa kutariswa nguva dzose (senge mutangi remafuta), nepo mune mamwe zvinongodiwa kuwana ruzivo nezve kuvapo kana kusavapo kwemvura, kana nezve mvura inokunda imwe nhanho (inodarika kana kudonha) .Basa rekutanga rinogadziriswa neinoenderera nhanho sensors, uye yechipiri, hydraulic alarm sensors (DGS) kana fluid level sensors inoshandiswa.
DGS yakaiswa mumatangi ekuwedzera, injini crankcase uye zvimwe zvinhu zve hydraulic system.Kana iyo mvura yasvika pane imwe nhanho, sensor inokonzereswa, inovhara kana kuvhura dunhu, ichipa on / off chiratidzo pane dashboard (semuenzaniso, chiratidzo chekudonha kwemafuta), kana kuvhura / kudzima ma actuators - pombi, madhiraivha uye vamwe vanopa shanduko muyero yemvura kana shanduko yeanoshanda modhi yeiyo yese hydraulic system.Ndokusaka DGS inowanzonzi sensors-signaling devices uye sensors-relays.
Pamichina yemazuva ano yemotokari, akasiyana-siyana masensa-hydraulic maalarm anoshandiswa - anofanirwa kutsanangurwa zvakadzama.
Mhando uye maitiro e hydraulic alarm sensors
Masensa anhasi akakamurwa kuva marudzi akati wandei zvichienderana nechimiro chemuviri wekushanda, nharaunda yekushanda (rudzi rwemvura) uye maitiro ayo, yakajairika chinzvimbo chevanobatika, nzira yekubatanidza uye hunhu hwemagetsi.
Zvinoenderana nemusimboti wekushanda, mota DGS yakakamurwa kuita mapoka maviri:
● conductometric;
● Kuyangarara.
Conductometric sensors dzakagadzirirwa kushanda nemagetsi conductive zvinwiwa (kunyanya mvura uye inotonhorera).Aya maDGS anoyera kupikisa kwemagetsi pakati pechiratidzo uye zvakajairika (pasi) electrodes, uye kana kushorwa kunodonha zvakanyanya, inotumira chiratidzo kune chiratidzo kana actuator.A conductivity sensor ine simbi probe (kazhinji yakagadzirwa nesimbi isina tsvina) uye yemagetsi dunhu (inosanganisira pulse generator uye chiratidzo amplifier).Iyo probe inoita mabasa ekutanga electrode, mabasa echipiri electrode anopihwa mugaba pachayo nemvura (kana iri simbi) kana simbi yesimbi yakaiswa pamwe nepasi kana madziro emudziyo.Iyo conductometric sensor inoshanda zviri nyore: kana chiyero chemvura chiri pasi peprobe, kupikisa kwemagetsi kunowedzera kusingagumi - hapana chiratidzo pakubuda kwe sensor, kana pane chiratidzo pamusoro pemvura yakadzika;Kana iyo mvura inosvika kune sensor probe, kushorwa kunodonha zvakanyanya (iyo mvura inoitisa ikozvino) - pakubuda kwe sensor, chiratidzo chinoshanduka kune chakapesana.
Float sensors inogona kushanda nechero rudzi rwemvura, zvese zvinoitisa uye zvisingaite.Nheyo ye sensor yakadaro inotenderera yeimwe dhizaini yakabatana neboka rekusangana.Iyo sensor inowanikwa pamuganho weiyo mvura inogona kusvika panguva yakajairika kushanda kweiyo system, uye kana iyo mvura yasvika padanho iri, inotumira chiratidzo kune chiratidzo kana actuator.
Kune marudzi maviri makuru emasensa ekuyangarara:
● Nekuyangarara kwakabatana kune inofambiswa kuonana kweboka rekusangana;
● Nemagnetic float uye tsanga chinja.
DGS yerudzi rwekutanga ndiyo yakapfava pakugadzira: yakavakirwa pane inoyangarara muchimiro chepurasitiki probe kana mhangura silinda yendarira yakabatana kune inofambiswa kusangana kweboka rekusangana.Kana chiyero chemvura chichikwira, iyo inoyerera inokwira uye pane imwe nzvimbo pane pfupi pfupi kana, pamwe chete, kuvhura kwevanobatika.
Masensa erudzi rwechipiri ane dhizaini yakawedzera kuomarara: iwo akavakirwa pane gomo tsvimbo ine tsanga switch (magnetic switch) iri mukati, pamwe neaxis iyo annular inoyangarara ine magineti isingaperi inogona kufamba.Shanduko muyero yemvura inoita kuti iyo inoyangarara ifambe neaxis, uye kana magineti inopfuura nepachinja rutsanga, mabatiro ayo anovharwa kana kuvhurwa.
Zvinoenderana nerudzi rwenzvimbo yekushanda, mota sensors-hydraulic maalarm akakamurwa kuita mana makuru marudzi:
● Yekushanda mumvura;
● Yekushanda muantifreeze;
● Yebasa mumafuta;
● Yekushanda mumafuta (peturu kana dhiziri).
Sensor-hydraulic detector ine simbi probe
Dhiagiramu ye sensor yekuyangarara ine inofambiswa yekubata
Dhiagiramu ye sensor yetsanga ine magnetic float
DGS yezvakasiyana midhiya inosiyana mumidziyo inoshandiswa, uye masensa anoyangarara anosiyanawo muhukuru hwezvinoyangarara kuti zvipe kusimudza kwakaringana munzvimbo dzakasiyana densities.
Zvinoenderana neyakajairwa chinzvimbo chevanobatika, ma sensors akakamurwa kuita mapoka maviri:
● Neanowanzo vhura mazita;
● Nemazita akavharwa.
Sensors inogona kuva nenzira dzakasiyana dzekubatanidza kumagetsi emagetsi: zvibatanidza zviri kure nemapanga ekubatanidza nemapanga, zvibatanidza zvakabatanidzwa nemapanga uye zvakabatanidzwa bayonet-type connectors.Kazhinji, motokari DGS ine mapini mana: maviri emagetsi ekupa ("plus" uye "minus"), chiratidzo chimwe uye imwe calibration.
Pamhando huru dzema sensors, zvinodikanwa kuratidza magetsi ekupa (12 kana 24 V), nguva yekunonoka yekupindura (kubva pakushanda kwepakarepo kusvika kunonoka kwemasekondi mashoma), tembiricha yekushanda, mashandisiro azvino, kukwira shinda uye saizi yeturnkey hexagon.
Dhizaini uye maficha emotokari sensors-hydraulic siginecha zvishandiso
Yese yemazuva ano mota DGS ine dhizaini yakafanana.Izvo zvinobva pamhangura yendarira, kunze kwayo kune shinda uye turnkey hexagon.Mukati mekesi mune chinhu chinonzwa (float probe kana simbi probe), boka rekuonana uye bhodhi rine amplifier / jenareta wedunhu.Pamusoro pe sensor pane chinongedzo chemagetsi kana tambo ye wiring ine chinongedzo pamagumo.
Iyo sensor inoiswa mutangi kana chimwe chinhu che hydraulic system uchishandisa shinda kuburikidza neO-ring (gasket).Nekubatsirwa kwekubatanidza, sensor inobatanidzwa kune motokari yemagetsi.
Mota inogona kuva neanosvika mashanu kana kupfuura masensa-hydraulic maalarm anoita mabasa ekutarisa huwandu hwehuturu, inotonhorera, oiri muinjini, fluid muhydraulic system, fluid mune simba steering, nezvimwe.
Maitiro ekusarudza uye kutsiva iyo sensor-hydraulic alarm
Liquid level sensorszvakakosha pakushanda kwemaitiro ega ega uye mota yese.Zviratidzo zvakasiyana-siyana zvinoratidza kuparara kweDGS - maaramu enhema ezviratidzo kana actuators (kuvhura kana kudzima pombi, nezvimwewo), kana, zvakasiyana, kusavapo kwechiratidzo pane chiratidzo kana actuators.Kuti udzivise kukanganisa kwakakomba, sensor inofanira kuchinjwa nekukurumidza sezvinobvira.
Kuti utsive, zvinodikanwa kutora masensa chete emhando idzo uye mhando dzinokurudzirwa neautomaker.DGS inofanira kuva nehumwe hukuru uye hunhu hwemagetsi, kana uchiisa sensor yeimwe mhando, iyo system inogona kusashanda.Iyo sensor inotsiviwa maererano nemirairo yekugadzirisa motokari.Kazhinji, basa iri rinouya pasi pakudzima sensor, kuiburitsa nekiyi, uye nekuisa sensor nyowani.Iva nechokwadi chekuchenesa nzvimbo yekuisa ye sensor kubva kune tsvina, uye shandisa O-ring (inowanzobatanidzwa) panguva yekuisa.Mune zvimwe zviitiko, zvingave zvakakosha kubvisa mvura kubva pachigadzirwa.
Sensors-hydraulic alarms
Mushure mekuisa, mamwe ma sensor anoda calibration, maitiro ayo anotsanangurwa mumirayiridzo yakakodzera.
Nekusarudzwa kwakakodzera uye kutsiva sensor-hydraulic alarm, chero system yakabatana nayo ichashanda zvakajairika, kuve nechokwadi chekuvimbika uye chakachengeteka kushanda kwemotokari.
