Puas yog M8 txuas mus tiv taus roj thiab tshuaj lom neeg?

一, cov roj tsis kam ua tau zoo: Dual se ntawm cov khoom xaiv thiab kev tsim cov khoom lag luam
1. Cov roj ua rau kev ua kom zoo ntawm cov hlau
Cov neeg hlau (xws li pins thiab thomets) ntawm M8 txuas yog feem ntau ua los ntawm tooj liab Nickel plating lossis stainless hlau khoom. Tus tooj liab Nickel plating cov txheej txheem ua yeeb yaj kiab cov yeeb yaj kiab uas tsis muaj roj av, uas tuaj yeem tiv thaiv cov roj ntxhia thiab tiv thaiv kom tiv thaiv kev sib chwv. Piv txwv li, tom qab 5 xyoos kev ua haujlwm txuas ntxiv hauv cov khoom siv roj av M8 txuas tau ruaj khov dua li 5m ω, tsawg dua lossis sib npaug nrog 10m ω).
Cov khoom siv hlau stainless hlau txuas ntxiv nthuav cov roj ua rau cov roj tsis huv, xws li cov khoom siv cov khoom noj muaj zog, thiab cov ntsiab lus molybdenum. Raws li cov ntaub ntawv xeem los ntawm qee qhov chaw tsim khoom lag luam, M8 txuas nrog lub cev muaj zog ntawm 31000 teev cov khoom siv tau zoo dua li 15% kev ua raws li cov khoom siv tooj dag.
2. Cov tshuaj muaj kuab paug rau kev sib khi
Cov qauv dej thiab cov plua plav (IP67 / IP66 / IP68) ntawm lub pob zeb tsis kam muaj qhov zoo rau cov roj tsis huv. Tsoos silicone o -} rings yog ib tus kom nthuav dav thiab deformation nyob rau hauv cov ntxhia roj, ua kom ntim tsis ua haujlwm. Txog rau qhov kawg, kev lag luam tau tsim cov ntaub ntawv tshwj xeeb xws li fluororubber (FKM) thiab hydrogenated nitrile roj hmab (HNBR):
Fluororubber: Nrog kub tsis kam ntawm -40 Qib rau +200 degree, nws tuaj yeem tiv thaiv muaj zog roj thiab roj hloov roj ntev. Cov ntaub ntawv ntawm qee cov khoom lag luam aviation cov khoom siv qhia pom tias kev ua yeeb yam ntawm M8 txuas tau raug kaw nrog fluorububber tsis tau txo qis tom qab jour-8 aviation kerosene rau 2000 teev.
Hydrogenated Nitrile Roj Hmab: Txhim kho cov roj tsis kam thaum tswj cov roj hmab elasticity los ntawm hydrogenation kev kho mob. Hauv kev sim ntawm cov kis tsheb kis las, lub HNBR kaw M8 tseem muaj tus nqi to taub tsawg dua 0.01cc / min tom qab 100000 lub voj voog ntawm kev cuam tshuam hauv ATF cov roj sib kis tau.
3. Cov roj ua luam kev txhim kho ntawm cable sheath
Lub Txuas Txuas Cable yuav tsum ua kom tau raws li cov kev xav tau ntawm cov roj ua rau muaj kev tiv thaiv, thiab hloov tsis kam rau tib lub sijhawm. Pur (Polyurethane) Sheathe) yog nquag mus rau hydrolysis thiab tsis ua tiav hauv cov chaw ntsuab vim nws cov qauv ester. Kev lag luam txhim kho nws cov roj tsis kam los ntawm kev hloov kho tshuab:
TPU (thermoplastic polyurethane): los ntawm kev qhia txog cov roj uas muaj ntxhiab ntawm cov tshuaj diesel thiab lubricating roj yog txo los ntawm 15% rau hauv qab 3%. Qhov ntsuas ntsuas ntsuas ntawm qee cov khoom siv tsim kev tsim kho kom muaj cov qauv siv tshuaj tua kab mob tom qab 5+85 degree.
PVC + GF (iav Fiber ntau txhawb polyvinyl chloride (xws li ntxiv cov roj tiv thaiv kab ntxwv), thiab tib lub sijhawm tiv thaiv paraffin), thiab cov laus tiv thaiv lub sijhawm hauv cov roj hauv hydraulic yog txuas ntxiv rau ntau tshaj 10 xyoo.
2, Tshuaj lom neeg tiv thaiv corrigion: ib txoj kev txhim kho los ntawm cov khoom ua haujlwm saum npoo av tiv thaiv cov txheej txheem kev tiv thaiv
1. Nto Protection Technology rau cov khoom siv hlau
Hauv cov kev sib raug zoo ntawm cov tshuaj lom neeg thiab cov khoom siv hlau thiab cov hlau uas yuav tsum tau kho cov chaw tiv thaiv sab:
Nickel phosphorus alloy plating: ib txheej amoy Kev ntsuam xyuas ntawm ib qho chaw ua liaj ua teb offshore tau pom tias M8 txuas rau ntawm thaj tsam ntawm 0.5% ntawm cov tshuaj ntsuab
Trunticent Chromium passivation: hloov cov qub hoxavalent cov txheej txheem dense oxide, uas tuaj yeem tiv thaiv cov acid acid corrosion xws li sulfroric acid thiab sulfuric acid. Kev kuaj cov ntaub ntawv qhia tau tias 316L stainless hlau ua rau muaj kev sib cav sib zog muaj 0.01mm / xyoo tom qab ₂ daws tau li 72 teev.
2. Tshuaj lom neeg Kev Hloov Kho ntawm cov khoom siv yas
Lub tsev txuas thiab cov txheej txheem rwb thaiv tsev yog feem ntau ua los ntawm engineering sulfide) lossis PPS (polyphenylene sulfide), tab sis cov tshuaj lom neeg kuj yuav tsum tau txhim kho los ntawm kev hloov kho:
PBT + PTFE (polytetrafluoroethylene): Ntxiv 5% PTFE Micro Hmoov tuaj yeem ua kom cov kuab tshuaj tiv thaiv PBT los ntawm 50%. Tom qab soakic volvents xws li toluene thiab acetone rau 30 hnub, lub tensile lub zog khaws nyiaj ntawm kev hloov PBT los ntawm 60% txog 85%.
PPS + GF (iav fiber ntau txhawb polyphenylene sulfide): kev sib ntxiv ntawm cov ntsuas kub kom txo tau nws txoj kev sib ntxiv ntawm cov khoom siv sib txawv (pH =14). Cov ntaub ntawv kev tshawb fawb ntawm semiconductor kev tsim khoom ua qhia pom tias M8 txuas nrog rau pps + GF plhaub tsis tau pom kev yeem hauv HF acid ist ib puag ncig rau 3 xyoos.
3. Kev tsim kho cov txheej txheem ntawm cov txheej txheem kev tiv thaiv
Rau cov tshuaj lom neeg muaj ntau lub adopts ntau yam kev tiv thaiv kev tiv thaiv:
Epoxy Resin encapsulation: tag nrho cov encapsulation ntawm cov ntawv hluav taws xob hluav taws xob ib ob txheej ntawm kev siv tshuaj lom neeg thib ob. Kev xeem tau ua nyob rau hauv ib qho dej phwj dej uas tau cog lus pom tias tom qab 50ppm) rau ib xyoos, lub rwb thaiv tsev ntau dua li 10m ω qhov pib ntawm cov khoom lag luam.
Ob chav txheej sealing qauv: ob lub nplhaib sib khi tau ntsia ntawm cov txheej txheem txuas mus tiv thaiv roj thiab cov txheej sab hauv ua los ntawm silicone to tiv thaiv dej vapor infiltration. Cov khoom ntsuas ntsuas ntawm qee cov khoom hauv dej hiav txwv uas qhia tau tias ob peb txuas rau ntawm M8 Pressor rau 0.001MG / cm ion ² ² ² ion ² ² ² ² ² met at ntawm qhov tob tob ntawm 500 meters (siab 5Mpa).
3, kev lag luam daim ntawv thov cov ntaub ntawv: Cov ntaub ntawv pov thawj ntawm cov roj thiab corrosion tsis kam ua
1. Petrochemical Kev Lag Luam
Nyob rau hauv catalytic crushing chav tsev ntawm lub tshuab hluav taws xob, M8 txuas ntxiv yuav tsum tau tiv thaiv dual kev sim ntawm kev kub siab ntawm 150-}}}}}}}}}}}} muaj cov roj ua pa. Ib qho kev lag luam ua kom tiav kev daws teeb meem customized ntawm 316L Standor Thaiv-15 xyoo, thiab txo tus txij nkawm txhua xyoo los ntawm 800000 Yuan.
2. Kev lag luam khoom noj khoom haus
Cov txheej txheem ntxuav ntawm cov khoom noj nqaij yuav tsum siv cov tshuaj tua kab mob (pH}}}}}}} Ib qho chaw nres tsheb siv tau M8 txuas nrog PPS + GF Plhaub thiab Trunentent Chromium passivated stomium passivated stomium passivated stomium passivated cov hlau stainless hlau. Tom qab 1000 lub voj voog ntawm cov siab kub (85 degree) Alkali ntxuav hauv CIP (tu hauv qhov chaw), cov neeg kho tshuab hauv qhov chaw khaws cia mus txog 92%, deb tshaj cov qauv kev lag luam ntawm 80%.
3. Nyob rau hauv daim teb ntawm lub zog hluav taws xob tshiab
Lub kaw lus txias ntawm lub zog hluav taws xob pob yuav tsum siv cov tshuaj tiv thaiv kab mob uas muaj ethylene glycol thiab dej (pH =8-10), thaum tseem tab tom ntsib kev co cuam tshuam. Ib lub tuam txhab tsheb ua kom zoo ntawm M8 txuas (siv HNBR seeding tsim), yog li ntawd cov kev sib txuas lus (}
