Mu gawo la ukadaulo wamakono wopangira zinthu, makina opangira zinthu zopopera mpweya amakondedwa kwambiri chifukwa cha luso lawo lokonza bwino zinthu zopopera mpweya. Pakati pawo, kupanga malo opangira zinthu zopopera mpweya ndi gawo lofunika kwambiri logwirira ntchito, lomwe limaphatikizapo mapangidwe angapo apamwamba komanso ntchito zogwirizana zaukadaulo.

Gawo loyamba popanga malo osungira mpweya pogwiritsa ntchito makina opopera mpweya pogwiritsa ntchito vacuum pressure ndi kupanga makina otsekera. Bowo lonse la zida zoponyera mpweya, kuphatikizapo chophimbira chomwe chili ndi chitsulo chosungunuka, bowo la nkhungu komwe kuli nkhungu, ndi mapaipi olumikizira, ziyenera kutsimikizira kutseka kwakukulu. Zipangizo zotsekera zapamwamba kwambiri, monga mphete zapadera zotsekera mphira, nthawi zambiri zimagwiritsidwa ntchito ndikuyikidwa pamalo olumikizirana a zigawo zosiyanasiyana zolumikizira ndi zinthu zosuntha kuti mpweya usalowe mkati panthawi yopopera mpweya. Mwachitsanzo, pamalo olumikizirana chitseko cha ng'anjo ndi bowo, payipi yotsekera yokonzedwa bwino yophatikizidwa ndi mphete yotsekera ya kukula koyenera ndi zinthu zimatha kupanga mawonekedwe odalirika otsekera mutatseka chitseko cha ng'anjo, ndikuyika maziko a ntchito zotulutsira mpweya pambuyo pake.

makina oponyera opopera opopera opopera

Kenako, makina opopera mpweya wa vacuum amagwira ntchito yofunika kwambiri. Makina opopera mpweya wa vacuum makamaka amakhala ndi pampu ya vacuum, mapaipi ofanana, ndi ma valve. Pampu ya vacuum ndi gwero lamphamvu lopangira vacuum, ndipo wamba ndi ma pump a rotary vane vacuum, ma pump a Roots vacuum, ndi zina zotero. Pambuyo poti pampu ya vacuum yayatsidwa, imalumikizidwa ku chipinda cha makina oponyera mpweya kudzera mu payipi ndikuyamba kutulutsa mpweya kuchokera ku chipinda. Pa gawo loyamba lotulutsa mpweya, mpweya mkati mwa chipinda umakhala wokhuthala, ndipo pampu ya vacuum imachotsa mpweya wambiri pamlingo waukulu wotulutsa. Pamene mpweya mkati mwa chipinda umakhala wochepa pang'onopang'ono, momwe ntchito ya pampu ya vacuum imagwirira ntchito idzasinthidwa malinga ndi zofunikira za digiri ya vacuum kuti isunge liwiro lokhazikika la kupopera ndi digiri yomaliza ya vacuum. Mwachitsanzo, pampu ya vacuum ya rotary vane imagwiritsa ntchito masamba ozungulira mkati kuti ikoke ndikufinya mpweya kuchokera ku doko lolowera, kenako nkuwutulutsa kuchokera ku doko lotulutsa utsi, ikuzungulira mosalekeza ndikuchepetsa kuthamanga kwa mpweya mkati mwa chipinda.

Kuyeza ndi kuyang'anira digiri ya vacuum ndikofunikira kwambiri pakutsuka vacuum. Makina oponyera ali ndi choyezera cha vacuum cholondola kwambiri, chomwe chimayesa digiri ya vacuum mkati mwa chipinda nthawi yeniyeni ndikubwezera deta ku dongosolo lowongolera. Dongosolo lowongolera limawongolera bwino momwe pompo ya vacuum imagwirira ntchito kutengera mtengo wokhazikika wa vacuum. Mwachitsanzo, ngati digiri ya vacuum yoyesedwa sinafike pa muyezo wokonzedweratu, dongosolo lowongolera lidzawonjezera mphamvu ya pompo ya vacuum kapena kukulitsa nthawi yopopera; Mlingo wa vacuum wofunikira ukafika, pompo ya vacuum idzalowa mu mkhalidwe wogwirira ntchito kuti zitsimikizire kukhazikika kwa malo otulutsa vacuum. Nthawi zambiri, digiri ya vacuum yomwe makina oponyera vacuum angachite ikhoza kukhala yotsika mpaka ma pascals makumi kapena kutsika. Malo okwera otere a vacuum amatha kuchotsa bwino zinyalala za mpweya m'bowo la nkhungu, kuchepetsa kulowerera kwa mpweya mumadzimadzi achitsulo panthawi yothira, ndikukweza kwambiri mtundu wa ma castings, kupewa kupangika kwa zolakwika monga porosity ndi kumasuka.

Kuphatikiza apo, kuti apititse patsogolo kukonza malo osungira mpweya ndikuwonetsetsa kuti ndi odalirika, makina oponyera mpweya wa vacuum alinso ndi zida zina zothandizira komanso njira zotetezera chitetezo. Mwachitsanzo, mafyuluta amayikidwa paipi yotulutsira mpweya kuti fumbi, zinyalala, ndi zina zotero zisalowe mu pompo ya vacuum ndikukhudza magwiridwe ake ndi moyo wake; Nthawi yomweyo, ili ndi chipangizo chodziwira kutuluka kwa mpweya wa vacuum, chomwe chingathe kuzindikira mwachangu ngati pali kutuluka pang'ono mu gawo lotsekera ndikupereka alamu kuti ikonzedwe nthawi yake. Komanso, ma valve owunikira nthawi zambiri amayikidwa pamalo olowera ndi otulutsira mpweya wa vacuum kuti apewe kubwerera kwa mpweya ndikuwonetsetsa kuti dongosolo la vacuum likugwira ntchito bwino.

Themakina oponyera opanikizika opanda vacuumyapanga bwino malo osungira zinthu zotayira mpweya omwe amakwaniritsa zofunikira za njira yotulutsira mpweya kudzera mu dongosolo lodzaza ndi kutseka, makina amphamvu opopera mpweya, kuyeza ndi kuyang'anira mpweya molondola, komanso zida zothandizira ndi njira zotetezera chitetezo. Malo osungira zinthu zotayira mpweya awa amapereka mikhalidwe yabwino kwambiri yothira ndi kupanga chitsulo chosungunuka m'chimake cha nkhungu, zomwe zimapangitsa kuti pakhale kusintha kwakukulu kwa kuchuluka kwa zinthu, mawonekedwe a makina, komanso khalidwe la pamwamba pa zinthu zopangidwa ndi ...
