Ifanele i-Isuzu common rail pressure sensor 499000-6160 4990006160

Indlela yokulinganisa ingcindezi iqhathaniswa nohlobo lokulinganisa ingcindezi.

1. Izifutho

Izinsalela zisetshenziselwa ukukala ingcindezi. Zingenziwa ngama-capsules aqoshiwe. Ikhiqizwa ngokuyisisekelo ngokuhlanganisa ama-diaphragm amaningi ndawonye. I-Bellows element iyilungu elilodwa elinwebekayo, eligoqekayo nelivumelana nezimo nge-axially. Ingenziwa ngocezu oluncane lwensimbi. Izingxenye ezivamile ze-bellows zenziwa ngamapayipi aginqikayo, amapayipi okudweba nge-hydroforming kanye nokuphenduka kusuka ezintweni eziqinile zensimbi. Imibhobho egcwele uketshezi ingasetshenziswa ezinhlelweni ezihlukahlukene zezinzwa.

(1) Izinzuzo zokubhodla

Izindleko ezimaphakathi

Letha amandla

Ukusebenza okuhle phakathi nobubanzi bengcindezi ephansi

(2) ukushiyeka kwepayipi likathayela

Ayifanele umfutho ophezulu

Idinga isinxephezelo sezinga lokushisa elizungezile

2. Inzwa yokucindezela kwengcindezi

Lolu uhlobo lokungenzi lutho lwenzwa yokucindezela kokumelana. Uma yeluliwe noma icindezelwe, ukumelana kwayo kuzoshintsha. I-strain gauge iwuhlobo locingo. Uma ingaphansi kokucindezeleka kwemishini, ukumelana kwayo kuzoshintsha ngenxa yemiphumela yomzimba. I-strain gauge ixhunywe ku-diaphragm. Uma i-diaphragm igobile ngenxa yokucindezela okusetshenzisiwe, i-gauge yobunzima izokwelula noma icindezele, futhi ukumelana kwayo kuzoshintsha ngenxa yalolu shintsho endaweni yayo ye-cross-sectional. Lolu shintsho luguqulelwa ekubeni lunikeze amandla kagesi ngokuxhumanisa amamitha amabili noma amane afanayo nebhuloho le-Wheatstone, ukuze okukhiphayo kukhuliswe futhi kuncishiswe ukuzwela kwamaphutha.

(1) Izinzuzo zenzwa yokucindezela kokucindezeleka

Ukugcinwa okulula nokufakwa okulula

Ukunemba okuhle nokuzinza

Isivinini sokuphendula esisheshayo

Ibanga elibanzi lokulinganisa

Azikho izingxenye ezihambayo namandla esignali aphezulu aphuma kumthamo webanga

(2) Ukungalungi kwenzwa yokucindezela kokucindezeleka

Idinga isinxephezelo sezinga lokushisa kanye nokunikezwa kwamandla kagesi njalo

Ukufundwa kwe-elekthronikhi kuyadingeka.

3. Inzwa yokucindezela kwe-Piezoelectric

I-Piezoelectric yikhono lezinto ezithile (ikakhulukazi amakristalu) ukukhiqiza amandla kagesi ukuphendula ukucindezeleka kwemishini. Kule transducer, umphumela we-piezoelectric usetshenziswa kwezinye izinto (ezifana ne-Shi Ying) ukuze kukhiqizwe amasignali kagesi asheshayo futhi kukale ubunzima obubangelwa ingcindezi kumshini wezinzwa. Izinhlobo ezijwayelekile zezinzwa zomfutho we-piezoelectric wuhlobo lwemodi yokushaja kanye nohlobo lwemodi ye-impedance voltage ephansi.

(1) Izinzuzo ze-piezoelectric pressure sensor

Ukusabela okuhle kwefrikhwensi, asikho isidingo sokunikezwa kwamandla kwangaphandle.

(2) Ukungalungi kwenzwa yokucindezela kwe-piezoelectric

Ukushintsha kwezinga lokushisa kuzothinta okukhiphayo, futhi ingcindezi emile ayikwazi ukulinganiswa.

4. Inzwa ye-piezoresistive

I-Piezoresistance inguquko yokumelana nezinto ezibangelwa ukuguqulwa kokucindezeleka ezintweni. I-piezoresistive gauge factor iyancipha ngokunyuka kwezinga lokushisa. Inzwa esebenzisa lo mphumela iyinzwa yokucindezela kwe-MEMS esekelwe ku-silicon, enezinhlelo eziningi zokusebenza, ezifana nokuzwa umfutho wegazi kanye nokuzwa umfutho wesondo.
