Iyo RE542461 inoshandiswa kuJohn Deere mafuta ekumanikidza sensor.

Sensors yekudzora injini

Kune akawanda marudzi ema sensors ekudzora injini, anosanganisira tembiricha sensor, kudzvanywa sensor, kumhanya uye angle sensor, kuyerera kwe sensor, chinzvimbo sensor, gasi rekugadzirisa sensor, kugogodza sensor uye zvichingodaro. Iri rudzi rwe sensor ndiyo musimboti weinjini yese. Kuzvishandisa kunogona kuvandudza simba reinjini, kuderedza kushandiswa kwemafuta, kuderedza gasi rekubuda, kuratidza kukanganisa, nezvimwewo. Nekuti vanoshanda munzvimbo dzakaoma senge injini vibration, peturu mhute, sludge uye mvura ine madhaka, indekisi yavo yehunyanzvi yekuramba nharaunda ine hutsinye yakakwira kupfuura. iyo yemasensa akajairwa. Pane zvakawanda zvinodiwa pazviratidzo zvekushanda kwavo, pakati peiyo inonyanya kukosha ndeyekuyerwa kwechiyero uye kuvimbika, kana zvisina kudaro kukanganisa kunokonzerwa nekuona sensor kunozopedzisira kwaita kuti injini yekudzora system kukundikana kana kukundikana.

1. Tembiricha sensor:

inonyanya kuona tembiricha yeinjini, tembiricha yegesi yekudya, tembiricha yemvura inotonhorera, tembiricha yemafuta emafuta, tembiricha yemafuta einjini, tembiricha inokonzeresa, nezvimwewo. Masensa anoshandiswa tembiricha anonyanya kupikisa waya ronda, thermistor uye thermocouple. Waya ronda rekudzivirira tembiricha sensor ine yakanyanya kurongeka, asi yakashata yekupindura maitiro; Thermistor sensor ine yakanyanya kunzwa uye yakanaka yekupindura maitiro, asi yakashata mutsara uye yakaderera inoshanda tembiricha. Thermocouple mhando ine yakanyanya kurongeka uye yakafara tembiricha yekuyera huwandu, asi amplifier uye kutonhora kupera kurapwa kunofanirwa kutariswa.

2. Pressure sensor:

inonyanya kuona kumanikidzwa kwakazara kwekutora manifold, vacuum degree, atmospheric pressure, injini yeoiri pressure, brake oil pressure, tyre pressure, etc. Kune marudzi akati wandei emota pressure sensors, pakati pawo capacitive, piezoresistive, variable inductance inofambiswa nediaphragm (LVDT). ) uye pamusoro elastic wave (SAW) inoshandiswa zvakanyanya. Capacitive sensor ine hunhu hwesimba rekuisa repamusoro, yakanaka simba remhinduro uye yakanaka kuchinjika kwezvakatipoteredza. Iyo varistor inopesvedzerwa zvakanyanya netembiricha, saka inoda kumisikidza tembiricha muripo wedunhu, asi yakakodzera kugadzirwa kwemazhinji. LVDT mhando ine yakakura yakabuda, iyo iri nyore kudhijitari kubuda, asi yayo vibration kuramba kwakashata; SAW inzwa yakanaka nekuda kwehukuru hwayo hudiki, huremu huremu, kuderera kwesimba rekushandisa, kuvimbika kwakasimba, kunzwisiswa kwakanyanya, kukwidziridzwa kwepamusoro uye kubuda kwedhijitari.
