Dab tsi yog qhov txawv ntawm ntom theem conveying thiab dilute theem conveying?Qhov zoo thiab qhov tsis zoo?

Txhawm rau kom nkag siab qhov sib txawv ntawm qhov ntom ntom conveying thiab dilute theem conveying, tshwj xeeb tshaj yog nyob rau hauv cov nqe lus ntawm cov kua mechanics, thiab muaj peev xwm tsim kom raug thiab calibrate pneumatic conveying systems.Calibration ceev thiab cua siab yog ib qho tseem ceeb heev nyob rau hauv lub pneumatic conveying system.Qhov tseeb ntawm qhov calibration feem ntau yog nyob ntawm hom khoom siv.

Dab tsi yog qhov ntom ntu conveyance txhais tau tias?

Nthuav theem conveying yog ib lub tswv yim tshiab hauv kev lag luam.Dense theem conveying, raws li lub npe implies, yog hais txog ib txoj kev densely conveying tej ntaub ntawv nyob rau hauv ib tug pipeline.Nyob rau hauv ntom theem conveying, cov khoom yuav tsis raug tshem tawm nyob rau hauv cov huab cua, vim hais tias cov khoom conveyed yog hnyav heev los yog abrasive heev, thiab ib tug siab ceev ceev yuav tsum tau khaws cia.Qhov no txhais tau hais tias cov khoom yuav raug thauj mus rau hauv daim ntawv ntawm "nthwv dej", "plugs" lossis "strands", kom tsis txhob hnav tsawg dua, yog li kev thauj mus los ntev yog tsim nyog rau cov khoom tawg yooj yim.

Dilute theem conveyance txhais li cas?

Dilute theem conveying cuam tshuam nrog kev xa tawm ntau ntawm cov ntaub ntawv dispersed, cov khoom no sib dua thiab ntau dua abrasive.Qhov no txhais tau tias piv nrog cov theem ntom ntom tshuab, khoom tuaj yeem yog xa mus rau ntawm kev ceev nrawm dua thiab siab dua.Piv txwv li, talc yog sib dua thiab tsis tshua muaj abrasive dua li cov khoom yas, yog li nws tuaj yeem thauj tau ntawm qhov nrawm dua thiab huab cua.Nyob rau hauv dilute theem conveying, ib tug blower yog siv los xa cov khoom mus rau hauv lub system los ntawm airflow.Lub airflow tsuas yog khaws cov khoom ntws thiab tiv thaiv cov khoom los ntawm kev tso rau hauv qab ntawm cov yeeb nkab.

Qhov sib txawv ntawm ntom theem conveying thiab dilute theem conveying hauv pneumatic conveying

Qee qhov sib txawv ntawm qhov ntom ntom conveying thiab dilute theem conveying yog qhov kev zam tsis tau vim tias lawv yog cov yam ntxwv ntawm cov khoom siv nws tus kheej-piv txwv li, dilute theem conveying feem ntau ua haujlwm sib dua.Cov hauv qab no yog qee qhov sib txawv ntawm qhov ntom ntom ntu conveying thiab dilute theem conveying:

1. Ceev: Qhov ceev ntawm dilute theem pneumatic conveying feem ntau yog ceev tshaj qhov ntom theem.Xav txog qhov abrasiveness ntawm cov khoom nqa, lub conveying ceev ntawm ntom theem yog qis dua.

2. Cua siab: cua siab nyob rau hauv cov ducts thiab cov kav dej ntawm lub dilute theem conveying system yog qis dua li ntawm dilute theem conveying los yog ntom theem pneumatic conveying.Lub siab ntawm dilute theem yog qis dua, thiab lub siab ntawm qhov ntom ntom yog siab dua.

3. Abrasion: Abrasion hais txog kev crushing ntawm hmoov.Nyob rau hauv dilute theem thauj, qhov poob tuaj yeem loj heev vim qhov ceev ntawm particle txav.Thaum nws los txog rau theem kev thauj khoom hnyav, qhov xwm txheej tsuas yog qhov sib txawv, vim tias nyob rau hauv cov txheej txheem no, cov ntaub ntawv loj feem ntau yog xa mus rau qis qis kom cov ntaub ntawv zoo thiab tsis yooj yim tawg.

4. Cov yeeb nkab loj: Cov yeeb nkab loj ntawm lub dilute theem kev thauj mus los yog feem ntau loj dua cov yeeb nkab loj ntawm cov txheej txheem kev thauj mus los hnyav.Ntau yam khoom siv hauv cov tshuab pneumatic conveying no kuj txawv me ntsis ntawm cov lus qhia tshwj xeeb, vim tias lawv qhov kev ua tau zoo nyob ntawm cov khoom uas lawv nqa thiab lawv cov abrasiveness lossis rhiab heev.

5. Tus nqi: Tus nqi ntawm kev tsim cov txheej txheem ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom txheej txheej txheej txheej txheej txheej txheej txheej txheej txheej txheej txheej txheej txheej txheej txheej txheej txheej txheej txheej txheej txheej txheej txheej txheej txheej txheej txheej txheej txheej txheej txheej txheej txheej txheej txheej txheej txheej txheej txheej txheej txheej txheej txheej txheej txheej txheej txheem yog siab dua, feem ntau yog vim qhov tshwj xeeb ntawm cov khoom siv.Piv nrog rau lub dilute theem conveying system, lub ntom theem conveying system kuj muaj zog.

6. Lub peev xwm thauj khoom lossis qhov sib piv: Lub dilute theem pneumatic conveying system muaj cov khoom siv roj tsawg tsawg.Nyob rau hauv sib piv, lub ntom theem system muaj ib tug siab heev cov khoom-gas huab hwm coj load piv.

7. Distance: Qhov siab tshaj plaws conveying nrug ntawm ntom theem conveying thiab dilute theem conveying kuj txawv: lub conveying nrug ntawm dilute theem system yog ntev dua, thaum lub conveying nrug ntawm ntom theem system feem ntau luv.
