M'munda waukadaulo wamakono woponya, makina oponyera vacuum amayamikiridwa kwambiri chifukwa cha kuthekera kwawo kukonza bwino ma castings. Pakati pawo, kupanga malo opanda kanthu ndi sitepe yofunika kwambiri yogwirira ntchito, yomwe imaphatikizapo mapangidwe apamwamba ndi ntchito zogwirira ntchito zamakono.

Chinthu choyamba pakupanga malo otsekemera ndi makina oponyera vacuum ndi kupanga makina osindikizira. Mphepete yonse ya zida zoponyera, kuphatikizapo crucible yomwe ili ndi chitsulo chosungunula, nkhungu yomwe imakhalapo nkhungu, ndi mapaipi ogwirizanitsa, ayenera kutsimikizira kusindikiza kwakukulu. Zida zosindikizira zapamwamba kwambiri, monga mphete zapadera zosindikizira mphira, nthawi zambiri zimagwiritsidwa ntchito ndikuyika pamagulu a magawo osiyanasiyana olumikizirana ndi zida zosuntha kuti mpweya usalowe mkati panthawi yopopera vacuum. Mwachitsanzo, pamphambano ya chitseko cha ng'anjo ndi patsekeke, kupangidwa mosamala kusindikiza poyambira pamodzi ndi mphete yosindikiza ya kukula koyenera ndi zakuthupi zimatha kupanga mawonekedwe odalirika osindikizira atatha kutseka chitseko cha ng'anjo, kuika maziko a ntchito zotsatsira vacuum.

makina opangira vacuum pressure

Kenako, makina opopera vacuum amakhala ndi gawo lapakati. Makina opopera vacuum makamaka amakhala ndi pampu ya vacuum, mapaipi ogwirizana, ndi ma valve. Pampu ya vacuum ndi gwero lamphamvu yopangira vacuum, ndipo zodziwika bwino ndi monga mapampu a vacuum a rotary vane vacuum, mapampu a vacuum a Roots, ndi zina zotero. Pampu ya vacuum ikayamba, imalumikizidwa kuchipinda cha makina oponyera kudzera papaipi ndikuyamba kutulutsa. mpweya wochokera kuchipinda. Mu gawo loyamba la kutulutsa mpweya, mpweya mkati mwa chipindacho ndi wandiweyani, ndipo pampu ya vacuum imatulutsa mpweya wambiri pamlingo wokwera kwambiri. Pamene mpweya mkati mwa chipindacho ukucheperachepera pang'onopang'ono, malo ogwirira ntchito a pampu ya vacuum adzasinthidwa malinga ndi zofunikira za digiri ya vacuum yokonzedweratu kuti apitirize kuthamanga kwa kupopa ndi digiri yomaliza ya vacuum. Mwachitsanzo, pampu ya rotary vane vacuum imagwiritsa ntchito zingwe zozungulira mkati kuti zikoke ndikukanikizira mpweya kuchokera padoko lolowera, ndikuutulutsa padoko lopopera, ndikuzungulira mosalekeza ndikuchepetsa kuthamanga kwa mpweya mkati mwa chipindacho.

Kuyeza ndi kuwunika kwa digiri ya vacuum ndikofunikira pakuchotsa vacuum. Makina oponyerawo amakhala ndi chowunikira chapamwamba kwambiri, chomwe chimayesa kuchuluka kwa vacuum mkati mwa chipindacho munthawi yeniyeni ndikubwezeretsanso deta kudongosolo lowongolera. Dongosolo lowongolera limayang'anira bwino ntchito ya pampu ya vacuum potengera mtengo womwe mukufuna. Mwachitsanzo, ngati digiri ya vacuum yoyezedwa isanafike pamlingo wokonzedweratu, dongosolo lowongolera lidzawonjezera mphamvu ya pampu ya vacuum kapena kuwonjezera nthawi yopopera; Mukangofikira mulingo wa vacuum womwe mukufuna, pampu ya vacuum idzalowa m'malo ogwirira ntchito kuti atsimikizire kukhazikika kwa chilengedwe cha vacuum. Nthawi zambiri, digiri ya vacuum yomwe makina oponyera mphamvu ya vacuum imatha kukhala yotsika ngati ma pascals kapena kutsika. Malo otsekemera oterewa amatha kuchotsa zonyansa za mpweya mu nkhungu, kuchepetsa kutengeka kwa gasi mumadzimadzi achitsulo panthawi yothira, ndikuwongolera kwambiri khalidwe la castings, kupewa kupezeka kwa zolakwika monga porosity ndi looseness.

Kuphatikiza apo, pofuna kupititsa patsogolo malo osungiramo vacuum ndikuwonetsetsa kudalirika kwake, makina oponyera mpweya wa vacuum alinso ndi zida zina zothandizira komanso njira zotetezera chitetezo. Mwachitsanzo, zosefera zimayikidwa pa payipi yotulutsa mpweya kuti muteteze fumbi, zonyansa, ndi zina zotere kuti zisalowe mu mpope wa vacuum ndikusokoneza magwiridwe ake ndi moyo wautumiki; Panthawi imodzimodziyo, imakhala ndi chipangizo chodzidzimutsa cha vacuum, chomwe chimatha kuzindikira mwamsanga ngati pali kudontha kwakung'ono mu gawo losindikiza ndikutulutsa alamu kuti ikonzedwe panthawi yake. Komanso, ma valve owunika nthawi zambiri amayikidwa polowera ndi kutulutsa mapampu kuti apewe kubweza kwa gasi ndikuwonetsetsa kuti makina a vacuum akuyenda bwino.

Themakina opopera vacuum pressurewapanga bwino malo otsekemera omwe amakwaniritsa zofunikira za kuponyedwa pogwiritsa ntchito makina osindikizira okwanira, makina opopera amphamvu a vacuum, kuyeza kolondola kwa vacuum ndi kuyang'anitsitsa, komanso mndandanda wa zida zothandizira ndi njira zotetezera chitetezo. Izi vacuum chilengedwe amapereka kwambiri yabwino mikhalidwe kuthira ndi kupanga chitsulo chosungunula mu nkhungu patsekeke, chifukwa kwambiri kusintha kachulukidwe, makina katundu, ndi pamwamba khalidwe la zinthu zotayidwa. Imalimbikitsa bwino kutukuka kwamakampani opanga makina opangira zinthu kuti akhale apamwamba komanso olondola, ndipo imagwira ntchito yofunika kwambiri m'magawo ambiri monga zakuthambo, kupanga magalimoto, ndi zodzikongoletsera.
