Inokodzera rori yemagetsi pressure sensor 1846481C92

Mechanical nzira

Mechanical kugadzikana kurapwa kunowanzoitwa kana chigadzirwa chakanyatso kuumbwa mushure mekubhadhara uye kugadziriswa kwemutoro sero redunhu uye chisimbiso chekudzivirira. Iwo makuru maitiro ipulse fatigue nzira, overload static pressure nzira uye vibration kuchembera nzira.

(1) Pulsating kuneta nzira

Sero rinotakura rinoiswa pamushini wepasi-frequency kuneta, uye muganho wepamusoro wakatemerwa mutoro kana 120% yakatarwa mutoro, uye kutenderera kuri 5,000-10,000 nguva pane frequency ye3-5 nguva pasekondi. Iyo inogona kunyatso kuburitsa iyo yasara kushushikana kwe elastic element, kuramba dhizaini gage uye kuomesa inonamira layer, uye mhedzisiro yekuvandudza zero point uye kugadzikana kwekunzwa kuri pachena.

(2) Overload static pressure nzira

Tichifunga, inokodzera marudzi ese ekuyeresa marenji, asi mukugadzirwa kunoshanda, aluminium alloy diki-renji simba sensor inoshandiswa zvakanyanya.

Maitiro acho ndeaya anotevera: mune yakakosha chiyero kurodha mudziyo kana yakapusa mekiniki screw yekurodha, shandisa 125% yakayerwa mutoro kune inotakura sero kwe4-8 maawa, kana shandisa 110% yakatarwa mutoro kwemaawa makumi maviri nemana. Maitiro ese ari maviri anogona kuzadzisa chinangwa chekuburitsa kwasara kushushikana uye kugadzirisa zero point uye kugadzikana kwekunzwa. Nekuda kwemidziyo yakapusa, mutengo wakaderera uye mhedzisiro yakanaka, iyo yakawandisa static pressure process inoshandiswa zvakanyanya nealuminium alloy load cell vagadziri.

(3) vibration kukwegura nzira

Iyo sero yekutakura inoiswa papuratifomu yevibration ine yakatemerwa sinusoidal thrust inosangana nezvinodiwa zvekuchembera kuchembera, uye frequency inofungidzirwa zvinoenderana neyakayerwa huwandu hwehuremu hwesero kuona iyo yakashandiswa vibration mutoro, kushanda frequency uye vibration nguva. Kuchembera kweresonance kuri nani pane kuchembera kwekudedera mukuburitsa kwasara kushushikana, asi maitikiro echisikigo eredhiyo sero anofanira kuyerwa. Vibration kuchembera uye resonance kuchembera kunoratidzwa nekushomeka kwesimba rekushandisa, nguva pfupi, mhedzisiro yakanaka, hapana kukuvadzwa pamusoro peiyo elastic zvinhu uye nyore kushanda. Iyo nzira yekuzunguza kuchembera haisati yakwana. Mafungiro nemaonero anoiswa mberi nenyanzvi dzekunze anosanganisira: dzidziso yeplastic deformation, fatigue theory, lattice dislocation slip theory, simba rekuona uye material mechanics maonero.
