Yog koj integrate ib qholub twj tso kua mis me merau hauv cov khoom siv kho mob, cov cuab yeej siv hauv chav kuaj mob, lossis daim ntawv thov kev lag luam, ib qho ntawm cov lus nug tseem ceeb tshaj plaws yog: "Nws tuaj yeem rub lub tshuab nqus tsev muaj zog npaum li cas?" Tshwj xeeb, rau ib qholub tshuab nqus tsev diaphragm, cov lus teb yog txhais los ntawm nws qhov siab kawg, qhov tseem ceeb uas txiav txim siab nws qhov tsim nyog rau koj qhov project.

Tsab xov xwm no piav qhia txog cov yam uas cuam tshuam rau qib nqus tsev ntawm cov twj tso kua mis no thiab yam koj tuaj yeem cia siab tau tiag tiag.

Lub twj tso kua mis diaphragm yog dab tsi?

Iblub tshuab nqus tsev diaphragmyog ib hom twj tso kua mis uas siv lub diaphragm elastomeric oscillating, check valves, thiab ib lub chamber los tsim lub tshuab nqus tsev. Lawv txoj kev ua haujlwm tsis muaj roj, qhuav ua rau lawv zoo tagnrho rau cov ntawv thov uas qhov huv thiab kev yooj yim nqa tau yog qhov tseem ceeb.

Qhov Ntau Yam Nqus Tsev Rau Cov Twj Tso Kua Me Me

Txawm hais tias lub peev xwm sib txawv raws li tus qauv thiab qhov zoo, feem ntau cov twj nqus tsev me me ntawm hom diaphragm ua tiav qhov nqus tsev zoo tshaj plaws (qhov siab qis tshaj plaws uas lawv tuaj yeem ncav cuag) hauv cov hauv qab no:

15 txog 29.9 nti ntawm Mercury (inHg) lossis 50 txog 760 Torr lossis -7 txog -100 kPa (gauge).

• Qis Kawg (Lub Hom Phiaj Dav Dav): ~15-20 inHg (-50 txog -67 kPa). Feem ntau siv rau hauv cov twj tso kua mis pheej yig dua rau kev siv xws li kev kuaj cua, kev nqus yooj yim, lossis kev tuav.

• Qib Siab (Kho Mob & Chav Kuaj Mob): ~22-29.9 inHg (-75 txog -100 kPa). Cov no yog cov twj tso kua mis ua haujlwm siab siv rau hauv cov ntawv thov uas nyuaj xws li kev ntsuas ntshav, kev lim dej, thiab cov khoom siv kuaj mob tsis siv neeg.

Rau cov ntsiab lus:

• Siab ntawm huab cua: 0 inHg (gauge) lossis 101.3 kPa (absolute)

• Lub Tshuab Nqus Tsev Zoo Tshaj Plaws: 29.92 inHg (gauge) lossis -101.3 kPa (gauge)

Qhov no txhais tau tias muaj cov khoom zoolub tshuab nqus tsev diaphragmtuaj yeem tshem tawm li ntawm 95-99% ntawm cov huab cua los ntawm qhov ntim kaw.

Cov Yam Tseem Ceeb Uas Txwv Tsis Pub Lub Twj Tso Kua Diaphragm Poob Qis Li Cas

Muaj ntau yam ntxwv tsim uas tiv thaiv lub twj tso kua mis diaphragm kom tsis txhob mus txog lub tshuab nqus tsev zoo meej:

1. Kev Ua Haujlwm Zoo ntawm Lub Tshuab Pa thiab "Lub Tshuab Pa Tuag": Tsis muaj lub twj tso kua mis twg uas yuav tshem tawm tag nrho cov cua ntawm lub tshuab pa. Muaj ib qho me me ntawm cov pa seem, hu ua "lub tshuab pa tuag," uas tseem raug kaw tom qab txhua zaus nias thiab rov nthuav dav, ua rau lub zog qis tshaj plaws uas ua tau.

2. Kev Xaim thiab Lub Qhov (Seal and Valve): Kev xaim me me dhau lub qhov (diaphragm seal) lossis lub qhov (check valves) yuav ua rau huab cua nkag rov qab mus rau sab nqus tsev. Cov twj zoo siv cov khoom siv uas tau ua tiav thiab cov khoom siv zoo tshaj plaws los txo qhov no.

3. Cov Khoom Siv Pa Tawm: Thaum lub tshuab nqus tsev, qee cov khoom siv (xws li qee cov yas lossis roj hmab) tuaj yeem tso cov pa lossis cov pa dej tawm ntawm lawv cov qauv. Qhov xwm txheej no, hu ua kev tawm pa tawm, ua rau muaj kev nyuaj siab hauv lub kaw lus thiab tsim ib lub hauv pem teb uas lub twj tso kua mis tsis tuaj yeem kov yeej.

4. Kev Yoog Tau thiab Kev Kaw ntawm lub diaphragm: Qhov kev ywj pheej ntawm lub diaphragm nws tus kheej txwv qhov sib piv ntawm kev nias. Lub diaphragm uas tawv dua tuaj yeem tsim lub tshuab nqus tsev muaj zog dua tab sis tej zaum yuav xav tau lub cev muaj zog dua thiab muaj kev sib pauv ntev sib txawv.

Cov ntawv thov los ntawm Lub Zog Nqus Tsev

• Lub Tshuab Nqus Tsev Qis (15-20 inHg / -50 txog -67 kPa): Cov khob nqus rau kev tuav, kev siv tshuab yooj yim, cov hnab kuaj cua, cov khoom siv nqus yooj yim.

• Lub Tshuab Nqus Tsev Nruab Nrab (20-25 inHg / -67 txog -85 kPa): Kev nqus tshuaj, kev ntsuas ntshav siab, lub twj tso kua mis, kev tswj cov kua tsis siv neeg, cov tshuab ntim khoom.

• Lub Tshuab Nqus Tsev Siab/Sib Sib (25-29.9 inHg / -85 txog -100 kPa): Kev lim dej hauv chav kuaj, kev tshem cov pa roj tawm hauv lub tshuab nqus tsev, kev siv cov khoom siv semiconductor, cov cuab yeej kuaj mob siab heev.

Yuav Ua Li Cas Xaiv Lub Twj Tso Kua Mis Kom Zoo Rau Koj Cov Kev Xav Tau Ntawm Lub Tshuab Nqus Tsev

1. Saib Daim Ntawv Qhia Txog Tus Kheej: Ib txwm nrhiav qhov ntsuas "Ultimate Vacuum" lossis "Final Vacuum", ntsuas hauv inHg, kPa, lossis Torr. Qhov no yog qhov siab qis tshaj plaws ntawm lub twj tso kua mis.

2. Xav Txog Qhov Nqus Dej: Lub twj tso kua mis yuav ua tiav qhov nqus dej tob, tab sis yog tias nws muaj qhov nqus dej qis (CFM lossis LPM), nws yuav siv sijhawm ntev heev kom mus txog qhov ntawd. Koj feem ntau yuav tsum sib npaug qhov nqus dej kawg nrog qhov ceev.

3. To taub Koj Lub System Xav Tau: Lub twj tso kua mis yuav tsum muaj zog txaus los kov yeej txhua qhov xau hauv koj lub system thiab tseem ua tiav qhov siab ua haujlwm xav tau rau koj daim ntawv thov.

4. Muab Qhov Zoo Tso Ua Ntej: Rau cov ntawv thov tseem ceeb, nqis peev rau hauv lub twj tso kua mis los ntawm lub chaw tsim khoom muaj npe nrov uas siv cov qhov dej thiab cov foob zoo kom ntseeg tau tias nws ua tau raws li nws qhov kev ua haujlwm nqus tsev.
