M'njira zopangira mafakitale pogwiritsa ntchito ukadaulo wa vacuum, mapampu a vacuum amagwira ntchito ngati zida zofunika kwambiri popanga malo ofunikira. Pofuna kuteteza mapampuwa kuti asaipitsidwe ndi tinthu tating'onoting'ono, ogwiritsa ntchito nthawi zambiri amaika zosefera zolowera. Komabe, ogwiritsa ntchito ambiri amafotokoza kuchepa kwa digiri ya vacuum mosayembekezereka pambuyo pa kukhazikitsa zosefera. Tiyeni tiwone zomwe zimayambitsa ndi njira zothetsera vutoli.
Kuthetsa Vuto la Vacuum Yochepetsedwa
1. Yezerani kutsika kwa digiri ya vacuum
2. Onani kusiyana kwa kuthamanga
- Ngati apamwamba: Bwezerani ndi zosefera zotsika
- Ngati zachilendo: Yang'anani zisindikizo / mapaipi
3. Tsimikizirani ntchito ya mpope popanda fyuluta
4. Funsani zomwe opanga amapanga
Zifukwa Zoyambira Zochepetsera Digiri ya Vacuum
1. Zosefera-Pampu Kugwirizana Nkhani
Zosefera zolondola kwambiri, pomwe zimapereka chitetezo chapamwamba, zimatha kuletsa kwambiri kuyenda kwa mpweya. Zosefera zowuma zimapanga kukana kwakukulu, zomwe zimatha kuchepetsa kuthamanga kwa kupopera ndi 15-30%. Izi zimawonekera kwambiri mu:
- Mapampu a rotary vane osindikizidwa ndi mafuta
- Machitidwe a ring ring vacuum
- Mapulogalamu apamwamba
2. Kusindikiza Zopanda Ungwiro
Mavuto osindikizira ambiri ndi awa:
- Zowonongeka za O-mphete kapena gaskets (zowoneka ngati zakuda kapena zophwanyika)
- Kuyanjanitsa kolakwika kwa flange (kuyambitsa kusalinganika kwa 5-15 °)
- Makokedwe osakwanira pa zomangira (nthawi zambiri zimafunika 25-30 N·m)
Malangizo Osankha Zosefera
- Fananizani kulondola kwa fyuluta ndi kukula kwenikweni koyipitsidwa:
- 50-100μm kwa fumbi ambiri mafakitale
- 10-50μm kwa tinthu tating'onoting'ono
- <10μm pokhapokha pazogwiritsa ntchito zipinda zoyera
- Sankhani zojambula zokongoletsedwa (40-60% malo ochulukirapo kuposa zosefera zathyathyathya)
-Yendetsani pre-installation:
- Tsimikizirani kukhulupirika kwa nyumba zosefera
- Onani elasticity ya gasket (iyenera kubwereranso mkati mwa masekondi atatu)
- Yezerani kusalala kwa flange (<0.1mm kupatuka)
Kumbukirani: Njira yabwino kwambiri yothanirana ndi chitetezo ndi zofunika pamayendedwe a mpweya. Ntchito zambiri zamafakitale zimapeza zotsatira zabwino kwambiri ndi zosefera zapakati (20-50μm) zokhala ndi:
- Mphepete zomangirira
- Nyumba zolimbana ndi dzimbiri
- Zolumikizana zokhazikika
Kwa zovuta zomwe zikupitilira, ganizirani:
- Kukwezera ku madera akuluakulu osefera
- Kukhazikitsa ma bypass valves pazoyambira
- Kufunsana ndi akatswiri a kuseferakwa mayankho achizolowezi
Potsatira malangizowa, malo amatha kukhala ndi ukhondo wamakina komanso magwiridwe antchito a vacuum, potsirizira pake amathandizira kupanga bwino komanso kukhala ndi moyo wautali wa zida.
