Chiwonetsero cha Zamalonda
Ubwino wa Zamankhwala
1. Ntchito yaing'ono ya danga: Poyerekeza ndi valavu ya tsinde yotseguka, tsinde lobisika la tsinde la valve limangoyenda mkati mwa thupi la valve ndipo silifuna malo owonjezera pamwamba pa valve, choncho ndiloyenera kwambiri kuyika ndi malo ochepa.
2. Mtengo wotsika: Mavavu a zipata zachitsulo zachitsulo nthawi zambiri amakhala otsika mtengo kuposa ma valve okwera pachipata.Mapangidwe osavuta komanso mawonekedwe a ma valve obisika a tsinde amachepetsa ndalama zopangira.
3. Itha kugwiritsidwa ntchito ngati valavu yachipata chapansi panthaka: Chifukwa tsinde la valavu yobisika ya tsinde silimawululidwa ndi mpweya, ikhoza kukhala yoyenera kugwiritsidwa ntchito pansi pa nthaka, monga machitidwe ogawa madzi ndi mapaipi apansi panthaka.
4. Zofunikira zochepa zosamalira: Poyerekeza ndi ma valve okwera, ma valve obisika a tsinde alibe tsinde lokwera kunja kwa thupi la valve, zomwe zikutanthauza kuti pali zigawo zochepa zosuntha zomwe zimafunikira kukonza kapena kudzoza, motero kuchepetsa kufunika kokonzekera nthawi zonse.
Chilichonse chidzachitidwa mawonekedwe, zakuthupi, kulimba kwa mpweya, kuthamanga ndi kuyesa zipolopolo musanachoke kufakitale;zinthu zosayenera siziloledwa kuchoka kufakitale.
Amagwiritsidwa ntchito ngati cutoff ndi zida zosinthira pamitundu yosiyanasiyana yamadzi ndi ngalande pepeline pomanga, mankhwala, mankhwala, nsalu, sitima ndi mafakitale ena.Vavu ya Zhongfa imatha kupereka ma valve olowera pachipata cha OEM & ODM ndi magawo ena ku China.Nzeru ya valavu ya Zhongfa ndikufunafuna zinthu zamtengo wapatali zokhala ndi ntchito yabwino kwambiri yokhala ndi mtengo wapamwamba kwambiri.Zogulitsa zonse za valve zimayesedwa kawiri musanatumize kuti zitsimikizire mtundu wa mankhwala.Takulandirani kudzayendera mafakitale athu.Tidzawonetsa Luso la mavavu.
