Chidule

Valavu ya gulugufe ya mtundu wa NSEN Flange Triple offset ingapereke kutseka mbali zonse ziwiri komanso mbali imodzi, kutengera zosowa za makasitomala ndi momwe ntchito ikuyendera. Koma chonde dziwani kuti mitundu yosiyanasiyana ya kutseka ndi kutseka ili ndi mitundu yosiyanasiyana.

• Kutseka kwa zigawo zambiri & Kutseka kwachitsulo kuchokera kuchitsulo kupita kuchitsulo

• Yolunjika mbali zonse ziwiri ndi yolunjika mbali imodzi

• Mphamvu yochepa yotsegulira

• Malo okhala osapukutidwa ndi kuzunguliridwa

• Mphamvu yokhala pansi

• Nkhope yotseka yokhotakhota

Kapangidwe

NSEN imapereka mwayi wokonza mpando wokhazikika ndi mpando woyandama womwe ungakonzedwe popanda kuchotsa valavu pamalo pake, izi zitha kufupikitsa nthawi yokonza ndikuwonjezera magwiridwe antchito. Mpando wokhazikika umagwiritsidwa ntchito pa valavu pomwe kuyenda kwapakati kumapita patsogolo, kotero kutseka kolimba kumangoyang'ana mbali imodzi, ndipo kuyenera kulabadira njira yoyendera pamene idayikidwa. Ngakhale mpando uli wokhazikika, koma kutseka kwa disc kumatha kuchotsedwa. Ngati valavu igwira ndi mpando woyandama, mutha kuyiyika mbali iliyonse.

Kapangidwe ka mpando woyandama wa NSEN

Mphamvu yotsika yotsegulira

Chigawochi chimagwiritsa ntchito Radial Dynamically Balanced Sealing System, pogwiritsa ntchito kapangidwe kabwino kwambiri, mphamvu zomwe zimagwiritsidwa ntchito mbali zonse ziwiri kuti zilowe ndi kutuluka kwa ma disc a gulugufe zimakhala zofanana kuti zichepetse mphamvu yotsegulira ma valve.

Nyanjalmphete  
Mphete yotsekera yopangidwa ndi laminated imapangidwa ndi mbale yachitsulo chosapanga dzimbiri yokhala ndi graphite/carbon fiber/PTFE etc. Poyerekeza ndi mbale ya rabara ya asbestos, zinthu zathu zogwiritsa ntchito ndizosavuta kuvala, sizimatsuka, ndizodalirika komanso ndizabwino kwa chilengedwe.

Mphete ya mpando yopangidwa ndi valavu ya gulugufe yotsekedwa ndi chitsulo imapangidwa ndi chitsulo chopangidwa ndi alloy chomwe chili ndi ubwino woletsa kukanda, kukana kutopa, kukana kuthamanga kwambiri ndi kutentha komanso kukhala ndi moyo wautali.

Dongosolo lolongedza katundu wamoyo
Kawirikawiri, anthu amangoyang'ana kwambiri kutuluka kwa madzi mkati mwa galimoto komwe kumachitika pa mpando koma amanyalanyaza vuto la kutuluka kwa madzi kunja, mwachitsanzo kutuluka kwa madzi m'galimoto. Kapangidwe kake kodzaza ndi zinthu zogwirira ntchito limodzi kamatsimikizira kuti valavu ya NSEN Butterfly imatha kutayikira bwino kuposa ≤20ppm. Izi zimapangitsa kuti kutseka kwa galimoto kukhale kodalirika komanso kumawonjezera nthawi yosungiramo katundu popanda kukonza.

Bokosi la zida

Bokosi la giya lamanja loperekedwa mwapamwamba komanso mwachitetezo, lomwe laphatikizidwa ndi zida zodziwika bwino za giya la mtundu wamakono komanso mulingo woteteza umafika pa IP 67.

Mphamvu ya Chigawo:Siteshoni yamagetsi yotenthetsera, siteshoni yosinthira kutentha, fakitale ya boiler yachigawo, kuzungulira kwa madzi otentha, makina a mapaipi oyambira

Malo oyeretsera zinthu:Madzi amchere, Mpweya wa carbon dioxide, chomera cha propylene, dongosolo la nthunzi, mpweya wa propylene, chomera cha ethylene, chipangizo chodulira cha ethylene, chomera chophikira

Malo opangira magetsi a nyukiliya:kudzipatula kwa zosungira, njira yochotsera mchere m'madzi a m'nyanja, njira yamadzi amchere, njira yopopera pakati, kudzipatula kwa pampu

Kupanga mphamvu ya kutentha: kuziziritsa kwa condenser, kusungunula kwa pampu ndi nthunzi, chosinthira kutentha, kusungunula kwa condenser, kusungunula kwa pampu

Kutentha kochepa:mpweya wamadzimadzi, makina a gasi wachilengedwe wosungunuka, makina obwezeretsa mafuta m'munda, malo opangira gasi ndi zida zosungira, makina oyendera gasi wachilengedwe wosungunuka

Zamkati ndi pepala:kudzipatula kwa nthunzi, madzi ophikira, laimu ndi matope

Kuyeretsa mafuta:Kupatula mafuta, valavu yoperekera mpweya, makina ochotsera sulfurization ndi purosesa ya gasi wotayira, mpweya woyaka, kupatula gasi wa asidi, FCCU

Gasi wachilengedwe

NSEN ikutsatira mosamalitsa ntchito zokonza zaulere, kusintha kwaulere ndi kubwezeretsa kwaulere mkati mwa miyezi 18 valavu itatha ntchito zakale kapena miyezi 12 itatha kuyikidwa ndikugwiritsidwa ntchito pa payipi pambuyo pa ntchito zakale (ndipo imayamba poyamba). 

Ngati valavu yalephera chifukwa cha vuto la khalidwe panthawi yogwiritsa ntchito mapaipi mkati mwa nthawi ya chitsimikizo cha khalidwe, NSEN ipereka chitsimikizo cha khalidwe chaulere. Ntchitoyi siidzatha mpaka kulephera kukhazikika ndipo valavuyo ikugwira ntchito bwino komanso kasitomala atasaina kalata yotsimikizira.

Pambuyo pa nthawi yomwe yatchulidwa, NSEN imatsimikizira kuti idzapatsa ogwiritsa ntchito ntchito zaukadaulo zabwino pa nthawi yake nthawi iliyonse yomwe chinthucho chikufunika kukonzedwa ndi kusamalidwa.
