Graphite Packing Yakasimbiswa NeInconel Wire

1. Chigadzirwa Core

Graphite Packing Reinforced with Inconel Wire imhando yepamusoro-yekuita composite sealing chigadzirwa. Inoshandisa yakakwirira-kuchena kwakawedzera graphite (ine kabhoni yeGreater than kana yakaenzana ne99.5%) se substrate, uye Inconel Wire (mainstream kiredhi: Inconel 625/825) inoiswa zvakafanana kuburikidza-kuruka axis uye nepamusoro-tembiricha yekupora. Hukoshi hwayo hwepakati huri mukubatanidza kusimba kwecorrosion, kusamira kwetembiricha, uye kuvhara kuita kwegraphite nesimba guru, creep resistance, uye yakakwirira-temperature oxidation resistance yeInconel Wire. Izvi zvinopedza marwadzo echinyakare graphite packing-zvakadai sekuda kushanduka, kuva nehupenyu hupfupi, uye kutadza kusimba-pasi pemamiriro ekushanda akanyanya "tembiricha yakanyanya, high pressure, nekuora kwakasimba", uye zvinopa zvigadziriso zvenguva refu{13}nezvakavimbika zvekunamira zvemichina mikuru yemuindasitiri.

3. Core Features

(1) Superb Mechanical Simba uye Creep Resistance

MuGraphite Packing yakasimbiswa neInconel wire, Inconel Wire (ine dhayamita ye0.15 ~ 0.3mm) inogoverwa zvakafanana pachikamu chechikamu che15% ~ 25%, iyo inowedzera simba rekutakura rekutakura kusvika Kukura kudarika kana kuenzana ne18MPa (80% yakakwirira kudarika iyo yakachena graphite packing) 0.5%/1000 maawa (pasi pemamiriro e200℃/ 15MPa). Inogona kuchengetedza kugadzikana munzvimbo-yepamusoro-yetembiricha uye{13}}yakakwirira{13}munzvimbo inodzvanyirira, ichinzvenga kusakonesa kuvharika kunokonzerwa neplastic deformation.

(2) Yakakura{{0}Range Temperature Resistance uye Oxidation Resistance

Kuramba tembiricha mumhepo: -200 dhigirii ~800 dhigirii (iyo oxidation-resistant coating yeInconel Wire inogona kutadzisa kutonhora kwakanyanya);

Kupikiswa kwekushisa mumhepo inert (nitrogen/argon): -200 dhigirii ~1200 dhigirii, iyo inopfuura kure tembiricha inoganhurwa yepurefite packing yakachena (Isingasviki kana kuenzana ne600℃mumhepo yemhepo). Iyo yakakodzera kune yakakwirira-tembiricha mamiriro senge supercritical boilers uye ndege injini yekubatsira masisitimu.

(3) Yakanakisa Chisimbiso Kuita uye Corrosion Resistance

Compression rate: 30% ~ 45%, rebound rate: Yakakura kudarika kana yakaenzana ne18%, dynamic sealing leakage rate: Zvisingasviki kana zvakaenzana ne0.05 milliliters / awa (test medium: saturated steam pa 150 degree, pressure: 20 bar);

Iyo graphite substrate inoshingirira mukuora kubva ku-spectrum acids nealkalis (pH 0-14), organic solvents, nemunyu wakanyunguduka. Inconel Wire inoshingirira ku chloride ion uye sulfide corrosion (semuenzaniso, midhiya ine munyu wakanyanya mumafuta ekumahombekombe uye gasi mapuratifomu), pasina njodzi yekuparara kwezvinhu.

(4) Low Friction Coefficient uye Long Service Life

Nzvimbo yekurongedza inobatwa ne polytetrafluoroethylene (PTFE) micro-coating, iyo inoderedza friction coefficient kusvika 0.12 ~ 0.15 pasi pemamiriro akaoma, uye kupfekedzwa kweshaft sleeve Ishoma kudarika kana kuenzana ne0.02 mm / 1000 maawa. Pasi pemamiriro ekushanda akajairika, hupenyu hwayo hwesevhisi hunogona kusvika maawa gumi nemaviri-12,000-18,000, iyo inopfuura 50% kureba kupfuura iyo yechinyakare graphite kurongedza, kudzikisa huwandu hwemichina yekuvhara uye basa rekugadzirisa.

(5) Yakasimba Engineering Adaptability

Zvakajairwa muchinjiko-kutsanangurwa kwechikamu: Sikweya (3mm×3mm~50mm×50mm), Circular (Φ3mm~Φ50mm); customized irregular cross-zvikamu (trapezoidal, wedge-zvakaumbwa) zvinotsigirwa;

Chikamu chevhoriyamu cheInconel Wire chinogona kugadziridzwa zvinoenderana nemamiriro ekushanda (kusvika pa30%) kuti chienderane nemakamuri akavharwa emazinga akasiyana-siyana (eg, akaderera-mavharuvhu epressure, akakwira-zvinobatisa pressure).

4. Minda Yekushandisa

(1) Indasitiri yeMasimba (Core Scenario)

Thermal power: Kuvharwa kweshaft ye supercritical boiler feedwater pumps, flange sealing of turbine condensers-inokwanisa kumira pamusoro-tembiricha uye yakakwirira{2}}pressure steam pa540℃/30MPa. Kuramba kweInconel Wire kunodzivirira kurongedzerwa kubva-panguva refu yekudzvanya deformation, uye hupenyu hwayo hwesevhisi hunobata kutenderera kukuru kwekugadzirisa bhairi (inenge mwedzi gumi nemisere);

Simba renyukireya: Kuvharirwa kwepombi dzekubatsira muzvitsuwa zvekutonhodza muchitsuwa chenyukireya (semuenzaniso, pombi dzemajekiseni ekuchengetedza)-Inconel 625 Waya inodzivirirwa nemwaranzi-inodzivirira (-ray dose Iri pasi kana kuenzana ne10⁷ Gy), uye graphite inoshingirira mukuora muboric acid solution. Inosangana neRCC-M nuclear material-grade material standard uye inova nechokwadi chekuvimbika pasi pemamiriro ekuchengetedzwa kwenyukireya.

(2) Petrochemical uye Oiri & Gasi Kuchera

Indasitiri yemakemikari: Kuvharwa kwemaagitator mukukwira-asidhi yetembiricha{1}}alkali reactors (eg, acetic acid synthesis reactors){4}}inoshingirira mukuora kubva kumhute yeacetic acid pa280℃/12MPa, uye kudonha kwemvura kunodzorwa kubva pasi pe 0 polliliters/0. leakage;

Offshore oil and gas: Kuvharirwa kwemavharuvhu emiti yeKisimusi yepasi pegungwa-inconel 825 Wire inoshingirira kumvura yegungwa chloride ion corrosion (hapana pitting corrosion mushure mekunyura mumvura yegungwa inosvika madhigirii 50 kwemaawa 1000), uye graphite inoshingirira mukukukurwa nemafuta emvura yakadzika{4} yakakwirira{{5}nzvimbo dzekudzvanyirira (Zvishoma pane kana kuenzana ne40MPa).

(3) Aerospace uye High-End Manufacturing

Kufamba nendege: Kuvharika kwepombi dzemafuta einjini yendege{0}}inokwanisa kutsungirira kushanduka kwetembiricha ye-50 madhigirii ~650 madhigirii. Inconel Wire inopesana nekuneta kuneta (hapana kuparara kwewaya pasi pe1000 Hz vibration), kuve nechokwadi chekushanda kwakagadzikana kweinjini pasi pemamiriro ekukwirira;

Metallurgy: Kuvharirwa kwemavharuvhu mumidziyo isiri -yesimbi inonyungudutsa (eg, copper smelting converters){3}}inokwanisa kumira ne800℃high-temperature yeflue gasi uye kumwaya simbi yakanyungudutswa, uye packing ine simba rekubvaruka reGreater than 2MP kana kutadza kudzika, kudzivirira kupisa kwepamusoro kana kutadza kudzika 2MP. gasi rinofashukira.

(4) General Indasitiri uye Special Minda

Indasitiri yemishonga: Kuvharwa kwemapoto ehari dzepamusoro-dzekudzivirira kupisa{1}}iyo graphite substrate inosangana neFDA 21 CFR Chikamu 177.2600 chikafu-chiyero chegiredhi, pasina kuwedzera kunaya kwemvura, uye inofambirana nezvinodiwa neGMP yakachena kugadzira;

Indasitiri yekutumira: Kuvharira pombi dzekutonhodza mvura yegungwa dzeinjini huru dzengarava-inconel Waya inoshingirira mukuora kwemvura yegungwa, uye graphite inoshingirira kunamatira kumvura yegungwa. Hupenyu hwesevhisi hwayo hunodarika maawa 20,000, zvichideredza zvinodiwa pakugadzirisa panguva yakareba-nzendo dzechikepe.

5. Supplementary Explanation

(1) Customized Service

Tinopa shanduro dzakagadziridzwa dze-giredhi reInconel Wire (semuenzaniso, Inconel 718, ine tembiricha yekudzivirira inokwidziridzwa kusvika pa850 degrees ) uye yakakwirira-purity graphite (99.9% kuchena). Isu tinotsigira machina echokwadi ane muchinjika-sectional dimensional tolerance we ± 0.05 mm, zvichiita kuti chigadzirwa chikodzere -makamera ekuvharisa (eg, mudziyo wemuchadenga).
