Tam sim no muaj cov txiaj ntsig tshawb nrhiav tsuas yog muab cov ntaub ntawv khoom siv los ntawm cov tuam txhab tsim khoom thiab tsis suav cov kauj ruam tshwj xeeb rau kev ntsuas qhov kub khiav LVDT sensor. Raws li kev paub dhau los hauv cov xwm txheej kub khiav, cov hauv qab no yog ua tiav cov txheej txheem calibration:
Kev Npaj: Npaj ib lub siab -precision digital multimeter thiab tus qauv hloov chaw. Tshav kub kub khiav mus rau nws qhov kev khiav hauj lwm kub thiab tuav rau 1-2 teev kom txog thaum lub thermal expansion ntawm cov qauv yog tag nrho ruaj khov. Tshem tawm cov khoom siv cuam tshuam thiab xyuas kom lub zog hluav taws xob muaj zog ruaj khov nyob rau hauv qhov ntsuas ntau.
Zero-Point Calibration: Ua kom kaw lub qhov kub ntawm rab koob valve thiab paub meej tias qhov chaw kho tshuab yog xoom. Hauv kev tswj hwm, teeb tsa LVDT tus nqi tso tawm ntawm lub sijhawm no raws li qhov kev hloov pauv xoom taw tes thiab kaw qhov kev siv txoj haujlwm.
Tag Nrho -Kev Tshawb Fawb Ntau Yam:
Siv cov txheej txheem hloov chaw los ntsuas LVDT tag nrho cov kab mob stroke los ntawm taw tes. Sau cov sensor tso zis qhov tseem ceeb ntawm qhov sib txawv txav. Kho qhov system tsis ua kom ntseeg tau tias qhov sib txawv ntawm qhov ntsuas tus nqi thiab tus qauv tus nqi yog tswj tsis pub dhau 0.5%, lav qhov linearity thoob plaws tag nrho cov hlab ntsha. Kub-kev pov thawj hauv xeev: Lub tshuab tsis siv neeg lub koob valve ua tiav ntau dua 10 puv -stroke qhib thiab kaw lub voj voog kom paub meej tias cov lus tawm tswv yim hloov pauv tsis muaj dhia lossis qeeb, yog synchronized tag nrho nrog rau qhov tseeb txhua yam, thiab tsis muaj lub tswb tshwm sim. Calibration tiav.
