Maitiro Ekusarudza Iyo Valve Handwheel Material Yakakodzera Kushandiswa MuHarsh Kunze Mamiriro Ekunze?

Tafura yezviri mukati

1. Indasitiri kumashure uye shanduko yekuda

2. Kuenzanisa kuongororwa kwemaitiro makuru ezvinyorwa

3. Zvinhu zvakakosha zvekusarudza munzvimbo dzakaoma

4. Ongororo yezvakajairwa zvekushandisa zviitiko

5. International standards uye certification system

6. Material innovation muna 2025

1. Indasitiri kumashure uye shanduko yekuda

Maitiro ekuiswa kwekunze kwezvivakwa zveindasitiri zvepasi rose ari kukurumidza. Maererano neshumo repagore ra2024 reInternational Valve Association, zvinodarika 62% zvemavharuvhu emuindasitiri anofanira kushanda munzvimbo dzakavhurika-pamhepo-dzakavhurika-pasi. Kunyanya mundima dziri kusimukira dzakadai sezviteshi zvemagetsi emagetsi matsva, mainjiniya emugungwa, uye tsvakiridzo yesainzi yepolar, mavhiri emaoko anotarisana nematambudziko mazhinji akadai semwaranzi yeultraviolet, kupfapfaidza munyu, uye jecha neguruva kupfeka. Hupenyu hwepakati hwesevhisi hwechinyakare chakakanda simbi mavhiri emaoko munzvimbo dzemahombekombe akadzikira zvakanyanya kubva pamakore gumi ari mumba kusvika kumakore 2-3 kunze, zvichimanikidza kudzokororwa kwehunyanzvi hwezvinhu.

2. Kuenzanisa kuongororwa kwemaitiro makuru ezvinyorwa

● Hunhu hwesimbi isina tsvina

1.316L austenitic Stainless simbi: kushanda kwakanakisa munzvimbo dzemugungwa dzine chloride ion concentrations Zvishoma pane kana kuenzana ne5000ppm, uye kuomarara kwepasi kunogona kusvika HV3503 mushure meanodizing.

2. Bidirectional Stainless simbi 2205: stress corrosion resistance yakawedzera ne40%, uye yakashandiswa mumavhiri emaoko emafuta uye gasi mapuratifomu muSouth China Sea.

3. Kuganhurirwa: kutonhora brittleness kunowanzoitika munzvimbo dziri pasi -40℃, uye antifreeze lubricant inofanira kushandiswa.

● Mabhindauko einjiniya mapurasitiki ekushandisa

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): tembiricha yemhando -100 dhigirii ~ 260 dhigirii, yakabudirira kutsiva simbi handwheels yeLNG kugamuchira zviteshi.

3. Yambiro yengozi: Pachine njodzi yekuzvimba munzvimbo dzakasimba dzeasidhi (pH＜2).

● Kudzidzira kwealuminium alloy yakareruka

1.7075 aruminiyamu yendege: micro-arc oxidation tekinoroji inoshandiswa kugadzira 50μm ceramic layer, uye muyedzo wekupfapfaidza munyu unodarika maawa 3000.

2. Huremu hwakanakira: 60% yakareruka pane mavhiri emaoko esimbi esimba rimwe chete, akakodzera kukwirisa-kukwirisa mamiriro ekushanda.

3. Conductive dziviriro: insulating coating layer inodiwa kudzivirira kupera kwe electrolytic.

● Mafambiro ekuvandudza mune zvakaumbwa zvinhu

3. Zvinhu zvakakosha zvekusarudza munzvimbo dzakaoma

●Corrosive media response plan

1. C4 level corrosion environment (ISO 12944): Zvinokurudzirwa kushandisa nickel-based alloy 625 handwheel, ine corrosion rate yepagore<0.01mm

2. Acid-base alternating working conditions: Hastelloy C-276 inofarirwa, ine pH yekushingirira kubva 0-14.

● Kunyanya kupisa kwekushisa kuchinja kushivirira kuedza

1. Kuderera kwekushisa kwekushisa: Modified polytetrafluoroethylene (PTFE) handwheels inofanira kushandiswa mu -60℃environment kuchengetedza kuoma uye kwete brittle.

2. High tembiricha countermeasures: 316 Stainless simbi handwheels vanofanira akashongedzerwa ne graphite lubrication system pasi 400 dhigirii kushanda mamiriro.

● Mechanical kutakura mutoro

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

2. Impact resistance design: Chimiro chemuzinga wehuchi chine 70% yakakwirira deformation resistance pane yakasimba.

●Anti-ultraviolet aging index

1. Kukurumidza kuchembera bvunzo: Yakapfuura QUV Ruoko rworuoko rwakaedzwa kwemaawa 3000 uye ine hupenyu hwebasa rekunze kweanopfuura makore masere.

2. Surface kurapwa: Ceramic coating inogona kuwedzera UV reflectivity kusvika 92%.

4. Ongororo yezvakajairwa zvekushandisa zviitiko

●A catalytic cracking unit of a refinery inoshandisa duplex Stainless steel handwheels, ave nemakore mashanu achishanda munzvimbo ine sarufa-ine oiri negasi pasina kana zviratidzo zvekuora. Key parameters:

1. Kupisa kwepakati: 280-400 degree

2. H2S concentration: 5000ppm

3. Kutenderera kutenderera: kwakawedzera kusvika kumwedzi gumi nemasere1

● Kusaita{{0}kuora kwenzvimbo dzekunze kwemahombekombe

Iyo East China Gungwa oiri uye gasi munda yakatsiva zvizere kabhoni fiber composite handwheels kuti iwane:

1. Kuora kwemunyu kwakadzikira nechikamu che90%.

2. Kuchengetedza mari yekuchengetedza ye2.2 mamiriyoni eyuan / gore

3. Kuderera kusingatarisirwi kwakaderedzwa nemaawa 150 / platform

● Desert environment durability verification

Iyo data yekuyedza yeSahara solar power station inoratidza:

1. The anti-dust wear life of engineering plastic handwheels is > 10 years

2. Kukasharara kwepamusoro kuchinja

3. Kushanda torque kushanduka siyana ± 5%

5. International standards uye certification system

6. Material innovation muna 2025

Nekubatanidzwa kwebudiriro yesainzi uye tekinoroji yedhijitari, mavhiri emaoko ekunze ari kusimukira akananga kugwara rine hungwaru re "self-kuzviona, -kuzvigadzirisa, uye kuzvichengeta-kuzvichengeta", zvichipa dziviriro yakasimba yekushanda kwakachengeteka kwenzvimbo dzemaindasitiri.
