Single chip vacuum jenereta CTA(B)-E yokhala ndi madoko awiri oyezera

Jenereta ya vacuum ndi gawo latsopano, logwira ntchito, loyera, lachuma komanso laling'ono lomwe limagwiritsa ntchito mpweya wabwino kuti upangitse kupanikizika koyipa, zomwe zimapangitsa kuti zikhale zosavuta komanso zosavuta kupeza kupanikizika koyipa komwe kuli mpweya woponderezedwa kapena pomwe kupanikizika kwabwino ndi koyipa. zofunika mu dongosolo pneumatic. Majenereta a vacuum amagwiritsidwa ntchito kwambiri pamakina, zamagetsi, zonyamula, zosindikiza, mapulasitiki ndi maloboti pamakina opanga mafakitale.

Kagwiritsidwe ntchito ka vacuum jenereta ndi mgwirizano wa vacuum sucker kutsatsa ndi kunyamula zinthu zosiyanasiyana, makamaka zoyenera kutsatsa zosalimba, zofewa komanso zoonda zopanda chitsulo kapena zinthu zozungulira. Pakugwiritsa ntchito kotereku, chinthu chodziwika bwino ndi chakuti mpweya wofunikira ndi wochepa, digiri ya vacuum sipamwamba ndipo imagwira ntchito modutsa. Wolembayo akuganiza kuti kusanthula ndi kafukufuku wa makina opopera a vacuum jenereta ndi zinthu zomwe zimakhudza momwe amagwirira ntchito ndizofunika kwambiri pakupanga ndi kusankha kwa mabwalo abwino ndi oyipa.

Choyamba, mfundo ntchito vacuum jenereta

Mfundo yogwirira ntchito ya jenereta ya vacuum ndiyo kugwiritsa ntchito mphunoyo kupopera mpweya woponderezedwa pa liwiro lalikulu, kupanga jeti pamalo otulutsira mphuno, ndikupanga kutuluka kwamadzi. Pansi pa kulowetsedwa, mpweya wozungulira potulutsa mphuno umayamwa mosalekeza, kotero kuti kupanikizika kwa adsorption cavity kumachepetsedwa kukhala pansi pa mphamvu ya mumlengalenga, ndipo mpweya wina wa vacuum umapangidwa.

Malinga ndi makina amadzimadzi, kuphatikizika kwa mpweya wa mpweya wosasunthika (gasi akupita patsogolo pa liwiro lotsika, lomwe limatha kuwonedwa ngati mpweya wosagwirizana)

A1v1= A2v2

Kumene A1, a2-gawo lodutsa mapaipi, m2.

V1, V2-kuthamanga kwa mpweya, m/s

Kuchokera pa ndondomeko yomwe ili pamwambayi, zikhoza kuwoneka kuti gawo la mtanda likuwonjezeka ndipo kuthamanga kwa magazi kumachepa; Chigawo chamtanda chimachepa ndipo kuthamanga kwa kuthamanga kumawonjezeka.

Kwa mapaipi opingasa, Bernoulli yabwino mphamvu equation ya incompressible mpweya ndi

P1+1/2ρv12=P2+1/2ρv22

Kumene P1, P2-kukanikizana kofanana ndi magawo A1 ndi A2, Pa

Kuthamanga kwa V1, V2-kogwirizana ndi magawo A1 ndi A2, m/s

ρ-kuchuluka kwa mpweya, kg/m2

Monga tikuonera pa chilinganizo pamwamba, kuthamanga amachepetsa ndi kuchuluka otaya mlingo, ndi P1 >> P2 pamene v2 >> v1. Pamene v2 ikuwonjezeka kufika pamtengo wina, P2 idzakhala yocheperapo kupanikizika kwa mlengalenga, ndiko kuti, kupanikizika koipa kudzapangidwa. Chifukwa chake, kupanikizika koyipa kumatha kupezeka powonjezera kuchuluka kwakuyenda kuti apange kuyamwa.
