Mavavu Okhazikika a Mpira Wazitsulo Zosapanga dzimbiri
Mawonekedwe
▪ Kukaniza kwamadzi ang'onoang'ono, mphamvu yake yolimbana nayo ndi yofanana ndi gawo la chitoliro cha utali wofanana.
▪ Kapangidwe kake, kamvekedwe kakang'ono ndi kulemera kopepuka.
▪ Kusindikiza kodalirika komanso kolimba.
▪ Ndi yosavuta kugwiritsa ntchito kutsegula ndi kutseka mwamsanga.
▪ Kusamalira bwino.Mapangidwe a valve ya mpira ndi osavuta, mphete yosindikizira nthawi zambiri imasunthika, ndipo ndiyosavuta kuyikapo ndikuyikapo.
▪ Njira zambiri zogwiritsira ntchito, zokhala ndi m’mimba mwake kuyambira mamilimita angapo kufika mamita angapo.
▪ Kukula kwa mapeto a flange a mndandanda wa valve kugwirizana kungapangidwe ndi kupangidwa malinga ndi zofuna za makasitomala.

Zigawo zazikuluzikulu ndi kusindikiza pamwamba zipangizo za mndandanda wa mavavu a mpira akhoza kupangidwa ndikusankhidwa malinga ndi zochitika zenizeni zogwirira ntchito kapena zofunikira zapadera za ogwiritsa ntchito. |
Kapangidwe
Kugwiritsa ntchito
▪ Ma valve opangidwa ndi zitsulo zosapanga dzimbiri amagwiritsidwa ntchito makamaka m'malo ogwirira ntchito omwe ali ndi zofunikira kwambiri pakuwononga, kupanikizika komanso ukhondo.Valve yachitsulo chosapanga dzimbiri ndi mtundu watsopano wa valve womwe wagwiritsidwa ntchito kwambiri m'zaka zaposachedwa.Mavavu a mpirawa amagwiritsidwa ntchito kwambiri podula kapena kuyendetsa mapaipi akutali mumafuta, gasi, mafakitale amafuta.
