1. Indasitiri kumashure uye kudiwa kwekutyaira
Nekukurumidza kukura kwesimba repasi rose, makemikari, kurapwa kwemvura uye mamwe maindasitiri,Gedhi Vavhavha Ruoko Wheel Sndiwo epakati ekudzora zvikamu zvemapombi masisitimu, uye kusarudzwa kwezvinhu zvemavhiri emaoko avo anofananidzira kunokanganisa zvakananga kushanda nekuchengetedzeka kwekushandisa kwemidziyo uye kugadzirisa. Sekureva kwe2024 mushumo weInternational Valve Association (IVA), musika wepasi rose wevhavhavhavha wasvika US$62 bhiriyoni, iyo iyo yakawedzerwa kukosha yakaunzwa nekuvandudzwa kwezvinhu zvemavhiri emawoko yakawedzera kusvika 18%.
Indasitiri yazvino inotarisana nematambudziko matatu makuru:
1. Mamiriro ekushanda akanyanya: Kuongorora kwakadzama-mafuta emugungwa negasi, magwenya emagetsi enyukireya nezvimwe zvinoonekwa zvakawedzera zvinodiwa pakusaita BP uye kusaora.
2. Hungwaru shanduko: Kuenderana zvinodiwa pakati pemagetsi / pneumatic drive zvishandiso uye handwheel zvinhu.
3. Mutengo wehupenyu hwakazara: Kubva pamutengo chaiwo wekutenga kusvika kune yakazara mutengo wekufunga kusanganisira kugadzirisa uye kutsiva
2. Core material classification uye hunyanzvi hunhu hwegedhi valve handwheels
● Kukanda simbi handwheel: ine mari uye shoma
Material properties:
(1.) Gray cast iron (HT200/250): compressive simba 200-250MPa, inodhura 30% yakaderera pane kabhoni simbi
(2.) Ductile iron (QT400-18): kureba kwakawedzera kusvika 18%, kukanganisa kupikisa kwakavandudzwa
Kuita:
Economical: 70% chikamu chemusika mune yakaderera-pressure water systems (Zvishoma pane kana kuenzana ne1.6MPa)
Kuganhurirwa:
(1.) Kurasika kwakashata: chiyero chekuora kwe0.5mm / gore munzvimbo dzine pH<4 or Cl⁻>200ppm

● Stainless simbi handwheel: mucherechedzo mumunda wekupokana nekuora
Material upgrade nzira:
(1.) 304 Stainless simbi: Ni content 8-10.5%, akakodzera general corrosion nharaunda
(2.) 316L simbi isina tsvina: wedzera 2-3% Mo, pitting resistance yakaenzana nePREN kukosha inosvika 281
(3.) Super duplex simbi: PREN kukosha kunodarika makumi mana, simba rinopetwa zvakapetwa kaviri resimbi yakajairwa.
Tekinoroji innovation:
Surface treatment process:
(1.) Electrolytic polishing: roughness Ra<=0.4μm, microbial attachment rate yakaderedzwa ne80%
(2.) PVD coating: kuoma kwakawedzera kusvika 2000HV, yakakodzera midhiya ine zvimedu zvakasimba.
(3.) Indasitiri kesi: Mushure memahombekombe ekemikari chirimwa chakatsiva kabhoni simbi handwheel nezvinhu 316L, kutenderera kwekugadzirisa kwakawedzerwa kubva kumwedzi mitatu kusvika kumakore maviri.
● Bronze handwheel: mhinduro yakasarudzwa yezviitiko zvakanyatsojeka
Zvinhu zvakanakira:
(1.) Pachako-zvivakwa zvekuzora: friction coefficient yakadzikira se0.15, yakakodzera kuvhurika nekuvhara nguva nenguva.
(2.) Precision casting: the dimensional tolerance inogona kusvika CT6 level, inokodzera yakakwirira-mavharuvhu chaiwo.
Performance parameter kuenzanisa:
| Indicators | Tin bronze (C83600) | Aluminium bronze (C95400) |
| Tensile simba (MPa) | 310 | 585 |

4. -kuongorora kwakadzama kwemaitiro ekushandiswa kweindasitiri
1. Oiri uye gasi kuongorora
Yakadzika-platform yegungwa: Titanium alloy handwheels haigadzirisike{{1}yemahara kwemakore gumi munzvimbo ine hudzamu hwemvura inosvika 1500m uye H₂S yemukati me300ppm.
Kubvisa gasi remushale: Nickel{{0}mavhiri emaoko anoshandiswa aruoyi anoshandiswa kugadzirisa jecha requartz richipfekwa mumvura.
2. Zvirongwa zvesimba idzva
Yakanyungudutswa munyu yekuchengetera kupisa: 316H Stainless simbi mavhiri emaoko anochengetedza kugadzikana kwechimiro munzvimbo yakanyungudutswa munyu ye565 degree.
Hydrogen simba pombi: Austenitic Stainless simbi mavhiri emaoko anopfuura iyo 140MPa hydrogen embrittlement bvunzo.
5. Chimiro chemusika wepasi rose uye maitiro ekuvandudza
1. Ongororo yemusika wedunhu:
Asia Pacific: 55% chikamu chemusika, China yekukanda maitiro ekusimudzira madhiraivha anodhura pasi ne20%
Musika wekuNorth America: Strict ASME B16.34 mwero unogadzira kudiwa kwepamusoro-end alloy handwheels
2. Technology maitiro ekufanotaura:
Intelligent sensor yekubatanidza: 30% yemavhiri emaoko achaiswa ne torque sensors muna 2026.
Zvinhu zvinogara zviripo: Mutengo we-based composite materials unotarisirwa kuenzana nesimbi dzechinyakare muna 2030.
6. Mutungamiri wekutenga uye mazano ekugadzirisa
Selection Matrix:
| Kushanda parameters | Zvinokurudzirwa zvinhu | Pfungwa huru |
| Temperature>400 degree | Nickel{{0}based alloy | High tembiricha simba, oxidation kuramba |
| Cl⁻ concentration>5000ppm | Super duplex simbi | Pitting yakakosha tembiricha |
| Kushanda kakawanda | Bronze + graphite lubrication | Pfeka kuramba uye kuvhura uye kuvhara torque |
Maintenance points:
(1.) Kukandira simbi handwheel: Tarisa uone kana ngura mwedzi mitanhatu yega yega uye shandisa WD-40 inodzivirira
(2.) Stainless simbi handwheel: Dzivisa kusangana zvakananga nekabhoni simbi maturusi kudzivirira kusvibiswa kwesimbi ion.
Mhedziso:
Nekubudirira mune zvesainzi uye tekinoroji yekugadzira,gedhi vharafu handwheelsvari kushandura kubva kuzvinhu zvinoshanda kuenda kuzvinhu zvakakwirira-zvakawedzerwa. Vatori vechikamu veindasitiri vanofanirwa kufambirana nekuvandudzwa kweASTM, ISO uye mamwe mazinga, uye kutarisisa kune zvinodiwa nemisika iri kusimukira yeakakosha ekushanda mamiriro ekugadzirisa, kuitira kuti vawane mukana mumusika wepasi rose unokwikwidza.
