Chilichonse Chimodzi Chulator CTA (B) - - ndi madoko awiri oyezera

Indunayi ya vacuum ndi gawo latsopano, labwino komanso loyera, laukadaulo lomwe limagwiritsa ntchito zovuta zina zomwe zimapangitsa kuti zikhale zovuta komanso zosavuta kupeza. Mitundu ya vacuum imagwiritsidwa ntchito kwambiri m'makina, zamagetsi, ma CD, kusindikiza, mapuloteni ndi maloboti ku makina opanga mafakitale.

Kugwiritsa ntchito kwachikhalidwe cha vacuum coneregar kumathandizira kuti adsorb ndi kunyamula zinthu zosiyanasiyana, makamaka zokhala ndi zida zofewa komanso zopyapyala. Mu mtundu uwu wa ntchito, chinthu chodziwika bwino ndichakuti kuyikiridwa kwa mpweya ndikochepa, digiri ya vacuum siitali ndipo imagwira ntchito mosamala. Wolemba akuganiza kuti kusanthula ndi kafukufuku pa makina opondera a vacuum conerator ndi zinthu zomwe zikukhudza magwiridwe ake ndizofunikira pakupanga ndi kusankha kwa madera osokoneza bongo.

Choyamba, mfundo yogwira ntchito ya vacuum generator

Mfundo yogwira ntchito ya vacuum ndikugwiritsa ntchito mphuno ya spraz yothira mpweya kuthamanga kwambiri, pangani ndege yopambana, ndikupanga zotulukapo. Pansi pa ntchito, mlengalenga mozungulira phokosoli amapitilirabe, kuti kukakamizidwa mu khungu la adsorption kumachepetsedwa kumaso kwa mlengalenga, ndipo mtundu wina wa vacuum umapangidwa.

Malinga ndi makina amadzimadzi, kuchuluka kwa mpweya wosagwirizana ndi mpweya (mpweya ukulankhulira mwachangu, komwe kungafanane ndi mpweya wosagwirizana)

A1V1 = A2V2

Komwe A1, A2-gawo la pamtanda wamapaipi, M2.

V1, v2-Airfrow velocity, m / s

Kuchokera pamwambapa, zitha kuwoneka kuti gawo la mtanda limakwera ndipo velocity yoyenda imachepa; Gawo la mtanda limatsika ndipo velocity yoyenda imachuluka.

Pazithunzi zopingasa, Bernoulline Ediction Edicy Equation wosagwirizana ndi

P1 + 1/11 = P2 + 1/1ρ22

Komwe ma P1, P2-Zolinga Zowonera Zigawo A1 ndi A2, PA

V1, v2-yolingana zofananira pazigawo A1 ndi A2, M / S

ρ-kachulukidwe ka mpweya, kg / m2

Monga momwe mungawonedwe kuchokera pamzere womwe uli pamwambapa, kupanikizika kumachepetsa ndi kuchuluka kwa kuchuluka kwa maluwa, ndi p1 >> v2 >> v1. V2 ikachulukanso pamtengo winawake, P2 idzakhala yocheperako mlengalenga umodzi, ndiye kuti, kukakamizidwa kolakwika kumapangidwa. Chifukwa chake, kukakamizidwa kolakwika kumatha kupezeka ndikukulitsa kuchuluka kwake kuti chizichotsetsa.
