Kusankha valavu yoyenera yapamadzi ndikofunikira kuti zitsimikizire kuti ntchito zake ndi zotetezeka, zogwira mtima, komanso zodalirika m'zombo ndi m'machitidwe akunja kwa nyanja. Ndi mitundu yambiri ya mavalavu ndi ntchito zomwe zimagwiritsidwa ntchito m'makampani a zapamadzi - kuyambira machitidwe a ballast mpaka ma cooling circuits, mizere yamafuta, ndi chitetezo cha moto - kusankha koyenera kumadalira zinthu zingapo zofunika.
1. Mvetsetsani Kugwiritsa Ntchito ndi Njira Yogwiritsira Ntchito
Dongosolo lililonse la m'madzi limagwira ntchito ndi mtundu winawake wa madzi (madzi, mafuta, mafuta, nthunzi, ndi zina zotero) pa mphamvu zosiyanasiyana, kutentha, ndi kuchuluka kwa madzi.
Dzifunseni kuti:
-
①Kodi ndi njira iti yomwe ikuyenda kudzera mu valavu? (monga madzi a m'nyanja, madzi abwino, mafuta, mafuta, gasi, nthunzi)
-
②Kodi chotchingacho chimawononga, chimakhuthala, kapena chimayaka?
-
③Kodi ndi njira yofunika kwambiri yotetezera (monga kuzimitsa moto, kuwotcha, kutseka mafuta)?
Langizo:Pa makina owononga kapena amchere, sankhanimkuwa, mkuwakapenamavavu achitsulo chosapanga dzimbiri.
2. Sankhani Mtundu Woyenera wa Valavu
| Mtundu wa Valavu | Zabwino Kwambiri |
|---|---|
| Valavu ya Mpira | Kuzimitsa mwachangu, kutsika pang'ono kwa kuthamanga kwa magazi |
| Valavu ya Chipata | Makina otseguka/otseka kwathunthu, opanda mphamvu zambiri |
| Valavu ya Globe | Kulamulira kayendedwe ka madzi kapena kupondereza madzi |
| Valavu ya Gulugufe | Kusunga malo, kuwongolera kuyenda kwa madzi ambiri |
| Valavu Yowunikira | Kuletsa kubwerera m'mbuyo |
| Valavu Yotetezera | Chitetezo chopitirira muyeso |
| Vavu ya Mphepo Yamkuntho | Kuwongolera kutulutsa madzi mwaukhondo |
3. Ganizirani Kugwirizana kwa Zinthu
Malo okhala m'nyanja amafuna zinthu zosagwira dzimbiri chifukwa chokumana ndi madzi amchere nthawi zonse, chinyezi, komanso kusintha kwa kutentha.
-
①Bronze/Mkuwa – Kukana dzimbiri bwino, komwe kumachitika m'madzi a m'nyanja
-
②Chitsulo Chosapanga Dzira - Kulimba bwino komanso kukana, koyenera kugwiritsa ntchito madzi othamanga kwambiri kapena owononga
-
③Chitsulo Chopangidwa ndi Cast – Chotsika mtengo, koma choyenera madzi osawononga okha
-
④Chitsulo cha Duplex/Super Duplex – Ma alloys ogwira ntchito kwambiri omwe amagwiritsidwa ntchito kwambiri
Langizo:Nthawi zonse gwirizanitsani zinthu za valavu ndi mapaipi ndi sing'anga kuti mupewe dzimbiri la galvanic.
4. Yesani Kuchuluka kwa Kupanikizika ndi Kutentha
-
①Chongani PN (Pressure Nominal) kapena Class rating
-
②Tsimikizani kutentha kwa ntchito
Ma valve ayenera kukwaniritsa kapena kupitirira zomwe zimafunika pa dongosolo ndikutsatira miyezo ya gulu la magulu.
5. Onetsetsani kuti bungwe la Classification Society lavomereza
Ma valve onse a m'madzi ayenera kukwaniritsa miyezo yapadziko lonse ya chitetezo cha m'madzi ndipo avomerezedwe ndi Mabungwe Oyenera Oyang'anira Magulu, monga:DNV (Norway).ABS (USA).BV (France).Kaundula wa Lloyd (UK).CCS (China)
Langizo:Onetsetsani kuti wopanga apereka zikalata zotsimikizira valavu iliyonse.
6. Sankhani Wopanga Valve Wodalirika wa Marine
Sankhani kampani yogulitsa ma valve a m'madzi yomwe:
-
①Ali ndi zaka zambiri akugwira ntchito mumakampani
-
②Imapereka mawonekedwe osinthika a pulogalamu yanu
-
③ Amapereka ma valve ovomerezeka, oyesedwa, komanso olembedwa
-
④ Imathandizira ntchito yogulitsa pambuyo pa malonda ndi upangiri waukadaulo
Qingdao I-FLOWndi mtsogoleriwopanga ma valve am'madzindi zaka zoposa 10 zakuchitikira. Timapereka mitundu yonse ya ma valve ovomerezeka a m'madzi, kuphatikiza ma valve a chipata, ma valve a globe, ma valve a gulugufe, ma valve owunikira, ma valve a storm, ndi zina zambiri — zombo zotumikira m'maiko opitilira 40 okhala ndi ziphaso za CE, DNV, ABS, ndi LR.
