2024 Tus sau: John Day | [email protected]. Kawg hloov kho: 2024-01-30 09:24

Lub hom phiaj rau cov lus qhia no yog piav qhia cov txheej txheem ntsuas ntsuas rau cov ntsuas ntsuas dej siv hauv chav kuaj. Cov Kauj Ruam 1-4 cuam tshuam txog kev ntsuas ntawm cov tshuab thaum Kauj Ruam 5-8 cuam tshuam txog cov ntaub ntawv tau txais.

Ua ntej ntsuas ntsuas, nws yog qhov yuav tsum tau ua ob peb kauj ruam kev nyab xeeb. Txheeb xyuas tias lub qhov dej tawm tau raug kaw, thiab qib ntawm cov mercury hauv cov kua dej-mercury. Lub ntsuas ntsuas yuav tsum tau tshuaj xyuas rau lub ntsuas hluav taws xob hydraulic. Yog tias qib tsis sib npaug koj tuaj yeem sib npaug lawv los ntawm kev qhib thiab kaw ob qhov ntsuas qhov ntsuas dej, kom tso pa tawm kom khiav tawm ntawm lub qhov dej ntws. Txheeb xyuas tias qhov ntsuas hauv nruab nrab muab qhov nyeem xoom, thiab kho kom haum.

Kauj Ruam 1: Xoom Transducer

Pib los ntawm xoom qhov hloov pauv hloov pauv ntawm Validyne qhov sib txawv siab hloov pauv, sau npe VFn interface lub thawv. Cov cuab yeej no nyob ze ntawm lub khoos phis tawj.

Kauj Ruam 2: Qhib Manometer Bleed Valve thiab Sau Cov Ntaub Ntawv

Qhib lub ntsuas ntsuas ntshav ntsuas lub npe 'CAL VALVE' txhawm rau txo qee qhov kev tsim khoom siab uas tau tshwm sim hauv ib ntawm kab kab ntsuas, thaum ua kom lub qhov tso tawm kaw. Nyob rau tib lub sijhawm, sau cov ntawv nyeem los ntawm lub zog hloov pauv (hauv volts) thiab qib manometer (hauv cm). LABVIEW software tau siv los kom tau txais cov txiaj ntsig. Yuav tsum muaj 5 cov ntsiab lus cov ntaub ntawv khaws tseg uas ncua los ntawm xoom siab mus rau qhov siab tshaj qhov sib txawv tau nrog cov ntshav ntws qhib siab.

Kauj Ruam 3: Txheeb Xyuas Qhov Tawm

Txheeb xyuas tias qhov tso tawm ntawm VF n tsis ntau dua 10V. Yog tias cov zis ntau dua 10V koj yuav tsum rov ua qhov ntsuas kom ntseeg tau tias A/D pawg thawj coj yuav nyeem qhov ntsuas hluav taws xob kom raug.

Kauj Ruam 4: Kaw 'CAL VALVE'

Kaw 'CAL VALVE'. Txoj haujlwm LABVIEW yuav ua qhov kev txheeb xyuas qhov tsawg tshaj plaws-xwmfab ntawm cov ntaub ntawv raws li nws tau sau, txhawm rau txiav txim siab qhov tseeb ntawm cov ntaub ntawv tom qab hauv kev tshuaj xyuas.

Kauj Ruam 5: Txheeb Xyuas Qhov Tau Txais Kev Tswj

Tom qab ntsuas ntsuas cov ntsuas ntsuas, npaj rau kev nrhiav cov ntaub ntawv. Nrhiav Pn hauv daim duab ob. Nov yog Gain Adjust tswj ntawm lub paddlewheel flowmeter. Txheeb xyuas qhov no tau teeb tsa rau 6.25 tig rau P1 thiab P4, thiab tau teeb tsa rau 3.00 tig rau P3.

Kauj Ruam 6: Xoom Lub Paddlewheel Flowmeter Output

Xoom lub paddlewheel flowmeter tso tawm los ntawm kev siv xoom kho tswj.

Kauj Ruam 7: Qhib Lub Valve Tso Tawm

Kauj ruam kawg yog qhib tus nqi tso tawm kom txog rau thaum qhov ntsuas pom tau zoo manometer deflection, lossis txog thaum nws qhib tag. Ua tib zoo mloog VFn kev nyeem ntxiv nrog rau Signet paddlewheel voltage nyeem. Thaum Signet paddlwheel qhov hluav taws xob loj thiab tsis yog xoom, sau ob qho tseem ceeb.

Kauj Ruam 8: Kev Sau Cov Ntaub Ntawv

Thaum cov kav dej tau mus txog lawv qhov siab tshaj plaws, lub paddlewheel flowmeter readings thiab manometer nyeem yuav tsum raug kaw. Siv lub sijhawm ntsuas qhov hnyav. Nrog LABVIEW software, sau lub sijhawm-nruab nrab siab-hloov pauv hluav taws xob. Sau qhov siab tshaj plaws manometer deflection,.

Rov ua cov txheej txheem no ntawm tus nqi qeeb qeeb. Qhov deflections rau kev ua tiav cov txiaj ntsig yuav tsum yog (.9^2), (.8^2), (.7^2), (.6^2), (.5^2),… (.1^2)) ntawm qhov siab tshaj plaws pom nyob hauv thawj qhov kev sim.
