Kupanikizika kwakukulu kwa pampu ya vacuum kuyenera kukumana ndi zovuta zogwirira ntchito popanga.Kwenikweni, kupanikizika kwakukulu kwa pampu yosankhidwa sikukhudza dongosolo la kukula kwake kuposa zomwe zimafunikira kupanga.Mtundu uliwonse wa mpope uli ndi malire ogwirira ntchito, kotero kuti malo ogwirira ntchito a pampu ayenera kumangidwa mkati mwamtunduwu, ndipo sangathe kusungidwa kwa nthawi yaitali kunja kwa mphamvu yovomerezeka yogwira ntchito.Pansi pa mphamvu yake yogwirira ntchito, pampu ya vacuum iyenera kutulutsa bwino kuchuluka kwa gasi wobwera chifukwa chopanga zida za vacuum.
Pamene mtundu umodzi wa mpope sungathe kukwaniritsa zofunikira za kupopera ndi kupukuta, m'pofunika kuphatikiza mapampu angapo kuti agwirizane wina ndi mzake kuti akwaniritse zofunikira za kupanga.Mapampu ena opanda vacuum sangathe kugwira ntchito pansi pa mphamvu ya mumlengalenga ndipo amafuna kuti asatayike;mapampu ena a vacuum ali ndi mphamvu yotulutsa yomwe siikwera kuposa mphamvu ya mumlengalenga ndipo imafuna mpope wakutsogolo, kotero onse amafunika kuphatikizidwa ndikusankhidwa.Pampu ya vacuum yomwe imasankhidwa kuphatikiza imatchedwa vacuum pump unit, yomwe imatha kupangitsa kuti vacuum ipeze digirii yabwino yopuma komanso kuchuluka kwa mpweya.Anthu ayenera kusankha pampu yolumikizira yophatikizika bwino, chifukwa mapampu osiyanasiyana amafunikira mosiyana kuti gasi atulutsidwe.
Mukasankha pampu yosindikizidwa ndi mafuta, muyenera kudziwa ngati vacuum yanu ili ndi zofunikira pakuyipitsidwa kwamafuta posachedwa.Ngati zida ziyenera kukhala zopanda mafuta, mitundu yosiyanasiyana ya mapampu opanda mafuta iyenera kusankhidwa, monga: mapampu a mphete zamadzi, mapampu a cryogenic, ndi zina zotero. Ngati zofunikira sizingatheke, mukhoza kusankha pampu yamafuta, kuphatikizapo Njira zotsutsana ndi kuipitsidwa kwamafuta, monga kuwonjezera misampha yozizira, misampha yamafuta, ma baffles, ndi zina zambiri, zimathanso kukwaniritsa zofunikira za vacuum.
Wodziwika bwino ndi mankhwala zikuchokera ku pumped mpweya, kaya mpweya lili condensable nthunzi, kaya pali tinthu akuyandama phulusa, kaya dzimbiri kukondoweza, etc. Posankha vacuum mpope, m'pofunika kudziwa mankhwala zikuchokera mpweya. ndi mpope lolingana ayenera kusankhidwa kwa mpweya wopopera.Ngati mpweya uli ndi nthunzi, zinthu zina, ndi mpweya wowononga mpweya, ziyenera kuganiziridwa kuyika zida zothandizira papaipi yolowera pampopi, monga condenser, chotolera fumbi, ndi zina zotero.
Posankha pampu yotsekemera yotsekedwa ndi mafuta, m'pofunika kuganizira momwe mpweya wamafuta (soot) umatulutsidwa ndi pampu yowonongeka pa chilengedwe.Ngati chilengedwe sichikuloleza kuipitsa, pampu yopanda mafuta iyenera kusankhidwa, kapena nthunzi yamafuta iyenera kutulutsidwa panja.
Kaya kugwedezeka komwe kumachitika chifukwa cha ntchito ya pampu ya vacuum kumakhala ndi vuto lililonse pakupanga ndi chilengedwe.Ngati kupanga sikuloledwa, pampu yopanda kugwedezeka iyenera kusankhidwa kapena njira zotsutsana ndi kugwedezeka ziyenera kuchitidwa.
