Momwe Mungasankhire Chida cha Valve Handwheel Choyenera Kugwiritsa Ntchito Panja Panja?

M'ndandanda wazopezekamo

1. Mbiri yamakampani ndi kusintha kwa zofuna

2. Kuyerekeza kuyerekeza kwa magwiridwe antchito apamwamba

3. Zinthu zazikuluzikulu zosankhidwa m'malo ovuta

4. Kusanthula zochitika zomwe zimagwiritsidwa ntchito

5. Miyezo yapadziko lonse lapansi ndi dongosolo la certification

6. Kupanga zinthu zatsopano mu 2025

1. Mbiri yamakampani ndi kusintha kwa zofuna

Ntchito yoyika kunja kwa mafakitale apadziko lonse lapansi ikupita patsogolo. Malinga ndi lipoti lapachaka la 2024 la International Valve Association, mavavu oposa 62 % a mafakitale amayenera kugwira ntchito pamalo otsegula-pampweya kapena pang'ono-potsegula-pa mpweya. Makamaka m'magawo omwe akubwera monga malo opangira magetsi atsopano, uinjiniya wam'madzi, ndi kafukufuku wasayansi wa polar, ma valve oyendetsa manja amakumana ndi zovuta zingapo monga cheza cha ultraviolet, corrosion ya mchere, komanso kuvala kwa mchenga ndi fumbi. Avereji ya moyo wautumiki wamagudumu am'manja achitsulo chachitsulo m'mphepete mwa nyanja watsika kwambiri kuyambira zaka 10 m'nyumba mpaka zaka 2-3 panja, kukakamiza ukadaulo wazinthu.

2. Kuyerekeza kuyerekeza kwa magwiridwe antchito apamwamba

●Makhalidwe a zitsulo zosapanga dzimbiri

1.316L austenitic chitsulo chosapanga dzimbiri: magwiridwe antchito abwino kwambiri m'malo am'madzi okhala ndi ma ion chloride Ochepera kapena ofanana ndi 5000ppm, ndipo kuuma kwapamtunda kumatha kufika HV3503 pambuyo pa anodizing.

2. Bidirectional zitsulo zosapanga dzimbiri 2205: kukana kupsinjika kwa dzimbiri kwawonjezeka ndi 40%, ndipo kwagwiritsidwa ntchito pazigawo zapamanja za nsanja zamafuta ndi gasi ku South China Sea.

3. Zochepa: Kuzizira kozizira kumakhala kosavuta kuchitika m'madera ochepera -40 digiri, ndipo mafuta oletsa kuzizira ayenera kugwiritsidwa ntchito.

●Kupititsa patsogolo ntchito zamapulasitiki zauinjiniya

1. Reinforced polyamide (PA66+GF30): passed ISO 4892-2 ultraviolet aging test, and the tensile strength retention rate after 5000 hours of irradiation is >85%.

2. Polyetheretherketone (PEEK): kutentha osiyanasiyana -100 digiri ~ 260 digiri , bwino m'malo magudumu am'manja achitsulo kwa LNG kulandira malo.

3. Chenjezo la Ngozi: Pali chiopsezo chotupa m'malo a asidi amphamvu (pH＜2).

● Mayeso opepuka a aluminiyamu aloyi

1.7075 aviation aluminiyamu: ukadaulo wa micro-arc oxidation umagwiritsidwa ntchito kupanga 50μm ceramic layer, ndipo kuyesa kwa kupopera mchere kupitilira maola 3000.

2. Kulemera kwake: 60% yopepuka kuposa mawilo achitsulo opangidwa ndi chitsulo amphamvu yofanana, oyenera kuchitira{2}}zitali zotalikirapo.

3. Conductive chitetezo: ndi insulating ❖ kuyanika wosanjikiza chofunika kupewa dzimbiri electrolytic.

●Njira zatsopano zopangira zinthu zosiyanasiyana

3. Zinthu zazikuluzikulu zosankhidwa m'malo ovuta

● Ndondomeko ya Corrosive media response

1. C4 level corrosion environment (ISO 12944): Ndibwino kuti mugwiritse ntchito faifi tambala-based alloy 625 handwheel, yokhala ndi dzimbiri pachaka<0.01mm

2. Acid-zikhalidwe zosinthira zoyambira: Hastelloy C-276 ndiyomwe imakonda, yokhala ndi kulekerera kwa pH kwa 0-14.

● Mayeso olekerera kusintha kwa kutentha kwambiri

1. Vuto la kutentha pang'ono: Mawilo osinthidwa a polytetrafluoroethylene (PTFE) akuyenera kugwiritsidwa ntchito mu -60 digiri chilengedwe kuti akhalebe olimba komanso osalimba.

2. Kutentha kwakukulu kwa kutentha: 316 zitsulo zosapanga dzimbiri zamanja ziyenera kukhala ndi makina opangira mafuta a graphite pansi pa 400 digiri ya ntchito.

● Kutha kunyamula katundu wamakina

1. Torque matching: DN200 valves are recommended to have a handwheel diameter of ≥400mm and an output torque of >300N.

2. Kamangidwe kakukana mphamvu: Wwilo lamanja la zisa lili ndi kukana kwa 70% kuposa mawonekedwe olimba.

● Anti-ultraviolet kukalamba index

1. Mayeso okalamba ofulumira: Anadutsa QUV Chiguduli cham'manja chayesedwa kwa maola 3000 ndipo chimakhala ndi moyo wautumiki wakunja kwa zaka zoposa 8.

2. Chithandizo chapamwamba: Kupaka kwa ceramic kumatha kukulitsa kuwala kwa UV mpaka 92%.

4. Kusanthula zochitika zomwe zimagwiritsidwa ntchito

●Chigawo chochititsa chidwi cha fakitale chimagwiritsa ntchito mawilo amanja a duplex zosapanga dzimbiri, omwe akhala akuyenda mosalekeza kwa zaka 5 m'malo a sulfure-wokhala ndi mafuta ndi gasi popanda zizindikiro za dzimbiri. Zofunikira zazikulu:

1. Kutentha kwapakati: 280-400 digiri

2. H2S ndende: 5000ppm

3. Nthawi yosamalira: kupitilira miyezi 181

● Mchitidwe woletsa{{0}kuwononga dzimbiri pamapulatifomu akunyanja

The East China Sea mafuta ndi gasi munda ali mokwanira m'malo mpweya CHIKWANGWANI gulu handwheels kukwaniritsa:

1. Zimbiri zopopera mchere zatsika ndi 90%

2. Kusunga ndalama zosungirako zokwana 2.2 miliyoni yuan/chaka

3. Kutsika kosayembekezereka kuchepetsedwa ndi maola a 150 / nsanja

● Kutsimikizira kulimba kwa chilengedwe chachipululu

Deta yoyeserera ya siteshoni yamagetsi ya solar ku Sahara ikuwonetsa:

1. Moyo woletsa -kuvala fumbi kwa injiniya wa ma wheel handwheel ndi > zaka 10

2. Kusintha makulidwe a pamwamba

3. Kusinthasintha kwa torque kumasiyanasiyana ± 5%

5. Miyezo yapadziko lonse lapansi ndi dongosolo la certification

6. Kupanga zinthu zatsopano mu 2025

Ndi kuphatikizika kwa zinthu zaukadaulo zasayansi ndiukadaulo wapa digito, mavavu akunja akuyenda kupita kumalo anzeru a "kudzimva-kudzimva-kusinthika, ndi kudzisamalira-kudzisamalira", kumapereka chitetezo chokhazikika pakugwira ntchito motetezeka kwa mafakitale.
