Ithuluzi lokuvala uhlobo lokusetshenziswa komoya ocindezelwe ngeqembu langempela le-vacuum lokucindezela okungalungile ukuze kutholwe futhi kuhlolwe ukusebenza kokuvala ukushisa kwezinto zokupakisha eziguquguqukayo zepulasitiki kanye nobuchwepheshe bokucubungula. Leli thuluzi lihlinzeka ngendlela yokuhlola ethuthukile, esebenzayo nephumelelayo yekhwalithi nokuthembeka kwephakheji yokuvala uphawu lwepulasitiki. Kulula ukuyisebenzisa, idizayini yomumo eyingqayizivele futhi inoveli yethuluzi, futhi kulula ukubona imiphumela yokuhlola, ikakhulukazi ukuthola ngokushesha nangempumelelo ukuvuza kwembobo encane yokuvala.
Ukusebenza kwensimbi yokuvala:
1. Vula iswishi yamandla. Amanzi ajovwa egunjini levacuum futhi ukuphakama kuphakeme kunendawo yepuleti elicindezelayo eliphansi ekhanda lesilinda. Ukuqinisekisa umphumela wokuvala, ufafaza amanzi amancane eringini yokuvala.
2. Vala isembozo sokuvala segumbi le-vacuum bese ulungisa ukucindezela enanini elizinzile elidingwa ukuhlolwa kugeji ye-vacuum pressure. Setha isikhathi sokuhlola entweni yokulawula.
3. Vula ikhava yokuvala yegumbi levacuum ukuze ucwilise isampula emanzini, futhi ibanga phakathi kwendawo engaphezulu yesampula nendawo yamanzi akufanele ibe ngaphansi kuka-25㎜.
Qaphela: amaphethini amabili noma ngaphezulu angase ahlolwe ngesikhathi inqobo nje uma ukuvuza kubonakala ezingxenyeni ezihlukahlukene zesampula phakathi nokuhlolwa.
4. Vala ikhava yokuvala yegumbi levacuum bese ucindezela inkinobho yokuhlola.
Qaphela: Inani le-vacuum elilungisiwe linqunywa ngokwezimpawu zesampula (njengezinto zokupakisha ezisetshenzisiwe, izimo zokuvala, njll.) noma izindinganiso zomkhiqizo ezifanele.
5. Ukuvuza kwesampula phakathi nenqubo yokucwenga kanye nesikhathi sokugcinwa kwe-vacuum ngemva kokufinyelela idigri ye-vacuum esethwe ngaphambilini kuncike ekutheni kukhona yini ukukhiqizwa kwebhamuza okuqhubekayo. Ibhamuza elilodwa elihlukanisiwe ngokuvamile alithathwa njengesampula yokuvuza.
6. Cindezela ukhiye we-back blow ukuze ukhiphe i-vacuum, vula isembozo sophawu, khipha isampula yokuhlola, usule amanzi endaweni yawo, bese ubheka umphumela womonakalo ebusweni besikhwama.
