PEB COV TXHEEJ TXHEEM Thaum Cov Roj Hmab Sib xyaw Nrog Cov Roj Hmab Sib xyaw

Cov roj hmab sib tov tshuab ua ke muaj peb qho txheej txheem hauv cov roj hmab sib xyaw ua ke: yob qhwv, noj hmoov, ua kom zoo nkauj thiab ua kom zoo nkauj.

1. Yob Wrapping

Thaum sib xyaw, yuav muaj plaub qhov xwm txheej uas cov roj hmab nyoos tshwm rau cov menyuam ntawm lub zeb qhib

Thawj qhov xwm txheej tshwm sim thaum cov menyuam siv hluav taws xob tsawg dhau los yog cov roj hmab nyuaj, ua rau cov roj hmab sib tw, lossis tsuas yog ua kom tawg thaum yuam kom tau nkag rau hauv.

Qhov xwm txheej thib ob tshwm sim thaum cov roj hmab nyob hauv lub xeev siab elastic, nrog ob qho yooj yim ntws thiab tsim nyog zoo heev deformation. Cov khoom siv roj hmab tsuas yog qhwv ib ncig ntawm cov menyuam yaus pem hauv ntej tom qab dhau los ntawm cov kev ua haujlwm sib kis, uas tau txais kev sib xyaw nrog cov khoom siv hauv cov khoom siv roj hmab.

Qhov xwm txheej thib peb tshwm sim thaum kub dhau lawm, cov roj hmab ua kom muaj zog, thiab cov kev sib txuam thiab muaj zog txo. Nyob rau lub sijhawm no, kev ua yeeb yaj kiab tsis tuaj yeem muab qhwv rau ib ncig ntawm cov menyuam thiab tsim lub hnab zoo li cov duab zoo li cov duab, ua rau cov menyuam yaus ua haujlwm, thiab tsis tuaj yeem sib xyaw.

Qhov xwm txheej thib plaub tshwm sim ntawm cov roj hmab siab dua, uas cov roj hmab hloov los ntawm lub xeev muaj kuab, nrog yuav luag tsis muaj lub zog viscous thiab lub zog, ua rau nws nyuaj txiav cov khoom siv roj tais. Yog li, qhov ntsuas kub ntawm kev sib xyaw yuav tsum tau tswj kom cov roj hmab cov ntaub ntawv hauv cov khoom zoo, uas yog qhov ua rau cov txheej txheem sib xyaw.

2. Noj hmoov

Cov hmoov noj theem yog hais txog cov txheej txheem ntawm kev sib xyaw cov neeg sawv cev sib xyaw rau cov khoom siv nplaum. Tom qab cov roj hmab roj hmab yog qhwv, nyob rau hauv thiaj li yuav muab cov kua nplaum sib xyaw rau hauv cov roj hmab, ib qho nqi ntawm cov kua nplaum puv yuav tsum tau khaws cov kua nplaum uas muaj cov menyuam sab saud.

Thaum ntxiv cov neeg sawv cev sib xyaw, vim kev hloov pauv ntawm cov kua nplaum thiab cov neeg sawv cev sib xyaw ua ke, cov neeg sawv cev sib xyaw ua ke tau txais cov kua nplaum thiab cov kua nplaum ntawm cov menyuam sib xyaw.

Thaum lub sij hawm cov txheej txheem ntawm kev noj mij, tus nqi ntawm cov kua nplaum uas tau sib npaug yuav tsum muaj qhov nruab nrab. Thaum tsis muaj kua nplaum lossis cov khoom siv tau ntau dhau yog cov khoom siv shear thiab cov roj hmab sib sib zog nqus rau hauv cov khoom siv roj hmab, uas cuam tshuam rau cov khoom siv roj hmab, uas cuam tshuam cov nyhuv khib nyiab; Ntawm qhov tod tes, hmoov ntxiv uas tsis tau rubbed rau hauv cov roj hmab yuav squeezed rau hauv daim los ntawm lub nraub qaum thiab poob rau hauv lub tais. Yog tias nws yog kua ntxiv, nws yuav lo rau lub nraub qaum lossis lub caij nplooj zeeg mus rau lub tais uas tau txais, ua rau muaj kev nyuaj rau kev sib xyaw.

Yog tias muaj ntau dhau kev sib txuam ntawm cov kua nplaum, qee cov kua nplaum yuav tig thiab ua rau nws tsis yooj yim rau cov menyuam yaus sib tsoo kom sib tsoo (lossis ua kom ntev dua ntawm 32-45.

3. Ua kom zoo thiab ua kom zoo dua

Theem peb ntawm kev sib xyaw yog rov ua kom zoo. Vim tias cov roj hmab siab ntawm cov roj hmab, thaum sib xyaw, cov roj hmab cov ntaub ntawv tsuas yog ntws hauv cov kev taw qhia kev sib hloov ntawm cov neeg qhib cov menyuam, tsis muaj axial txaus. Ntxiv mus, cov roj hmab ntws hauv txoj kev taw qhia yog Laminar. Yog li ntawd, txheej txheem sab hauv, cov nplaum nplaum uas zoo nkauj uas zoo nkauj rau saum npoo ntawm li 1/3 ntawm cov duab ua kom ntws tawm thiab ua "cov txheej txheem tuag" lossis "stagnant txheej" lab.

Tsis tas li ntawd, cov kua nplaum sib txuas rau sab qaum kev ntawm cov menyuam sib cav yuav tseem ua tau ib qho wedge-puab "Reflux Deb Zone". Cov laj thawj saum toj no tag nrho cov txiaj ntsig nyob rau hauv tsis ncaj ntawm tus neeg sawv cev hauv cov khoom siv roj hmab.

Yog li ntawd, nws yog ib qho tsim nyog yuav tsum tau dhau los ntawm ntau cov puag ncig ntawm kev ua kom zoo nkauj, txiav nrog sab laug thiab sab xis, thiab cov roj hmab sib xyaw, thiab ua kom muaj kev sib xyaw thiab ua kom zoo nkauj thiab zoo nkauj thiab muaj kev sib xyaw.
