Qhov zoo ntawm kev kho cryogenic ntawm li qub thiab cov xwm txheej ntawm cov ntawv thov kev lag luam

Qhov zoo ntawm cryogenic kev kho ntawm li qub thiab raws li txoj cai ntawm kev lag luam daim ntawv thov uas tsis tshua muaj kub cryogenic ua technology yuav ho txhim kho lub neej kev pab cuam ntawm cov ntaub ntawv yog: high-speed steel, cuab yeej steel, tuag steel, tooj liab electrode, hmoov cov ntaub ntawv, nyuaj alloy, ceramic, thiab lwm yam. Piv txwv ntawm kev siv cov kev kho mob cryogenic kom ntev lub neej kev pab cuam ntawm cov khoom los ntawm qee lub tuam txhab Asmeskas thiab qee qhov suav suav tau qhia hauv Table 2 thiab Table 3, feem. Table 4 qhia txog qhov sib npaug ntawm kev hnav tsis kam hloov ntawm qee cov khoom siv feem ntau siv tuag tom qab kev kho cryogenic. tuaj yeem txhim kho hnav tsis kam; Txhim khu lub zog thiab toughness; Txhim kho corrosion kuj, hnav tsis kam; Txhim khu kev cuam tshuam; Ua kom qaug zog ntxiv... Kev sib txuas sab saud: Valve cryogenic kho txoj cai thiab nws daim ntawv thov hauv kev lag luam (2) Qhov zoo thiab muaj daim ntawv thov kev kho cryogenic 3.1 Lub ntsiab zoo ntawm kev kho cryogenic tuaj yeem txhim kho hnav tsis kam; Txhim khu lub zog thiab toughness; Txhim kho corrosion kuj, hnav tsis kam; Txhim khu kev cuam tshuam; Txhim kho qaug zog; Tom qab kev kho cryogenic, nws tuaj yeem ua kom ntseeg tau tias cov khoom siv kho mob ib txwm muaj cov khoom siv kho kom zoo dua qub; Tsis ua rau cov duab loj deformation; tuaj yeem siv rau cov khoom siv tshiab / siv; tuaj yeem tshem tawm kev ntxhov siab sab hauv; Txhim kho cov khoom ruaj khov; Tus nqi ua haujlwm tsawg, vim tias kev ua kom lub neej ntev ntawm lub cuab yeej tuaj yeem txo lub sijhawm ntawm cov cuab yeej hloov thiab sib tsoo, kom txuag tau cov nqi tsim khoom; Ua tiav cov txiaj ntsig zoo ib yam li lwm yam kev kho saum npoo (xws li Chin plating, chrome, Teflon); Tighter molecular structures tuaj yeem tsim tau, txo kev sib txhuam, kub thiab hnav ntawm qhov chaw loj dua. 3.2 Lub luag haujlwm tseem ceeb uas tuaj yeem ua tiav los ntawm kev kho cryogenic Txiav cuab yeej; Internal combustion engine qhov chaw; * * * raj; Coj mus rhaub; Transmission ncej; Cov cuab yeej kho mob; me ntsis; Lub crankshaft. Agricultural machinery accessories; milling cutter; CAM; Suab paj nruag; Indexable hniav; Axis; Stainless hlau; Tuag; iav; Nickel puag alloy; Progressive tuag.

Piv txwv ntawm kev siv cov cryogenic kev kho mob kom ntev lub neej kev pab cuam ntawm cov khoom los ntawm ib co American tuam txhab uas muag thiab ib co Suav units muaj nyob rau hauv daim duab 2 thiab Table 3, feem. Table 4 qhia txog qhov sib npaug ntawm kev hnav tsis kam hloov ntawm qee cov khoom siv feem ntau siv tuag tom qab kho cryogenic. Raws li tuaj yeem pom los ntawm peb cov lus hauv qab no, kev kho cryogenic ua rau muaj qhov sib txawv ntawm cov khoom thiab cov cuab yeej ntawm cov khoom sib txawv, thiab kev hnav tsis kam ntawm cov khoom thiab cov cuab yeej tau zoo dua. 3.3.2 Txhim kho qhov ruaj khov ntawm cov ntaub ntawv Txhim kho qhov ruaj khov ntawm cov ntaub ntawv yog lwm qhov kev ua tiav ntawm kev kho cryogenic hauv txhuas, tooj liab, Chin thiab 300 series stainless hlau, tshwj xeeb tshaj yog txhuas thiab nws cov alloys. 3.3.3 Txhim kho cov khoom siv Cryogenic kho tuaj yeem txhim kho thiab txhim kho cov khoom siv, xws li lub zog, qaug zog, tiv thaiv corrosion, thiab lwm yam. Table 5 qhia cov txiaj ntsig tau los ntawm kev siv cov kev tshawb fawb hauv tsev kawm ntawv thiab kev tshawb fawb hauv kev lag luam. Nrog rau txoj kev loj hlob ntawm kev lag luam niaj hnub, cov kev xav tau ntawm cov khoom siv yog siab dua thiab siab dua. Muaj ob lub ntsiab lus tseem ceeb hauv kev tshawb fawb cov ntaub ntawv tam sim no: ① Tsis tu ncua tsim cov thev naus laus zis tshiab, cov txheej txheem tshiab thiab cov cuab yeej tshiab los tsim ntau yam khoom tshiab nrog cov kev xav tau tshwj xeeb lossis cov khoom zoo heev, xws li kev sib zog ceev ceev, kev sib tsoo, kev siv dav hlau, kev txhaj tshuaj molding thiab lwm yam. Cov txheej txheem los tsim microcrystalline, amorphous, quasicrystal, nanocrystalline structural thiab cov khoom siv. ② Rau cov ntaub ntawv uas twb muaj lawm xws li hlau thiab hlau, txhuas, tooj liab siv ultra-ntshiab purification, loj deformation ua, cryotreatment thiab lwm yam tshwj xeeb ua thiab ua technology, nyob rau hauv lub hauv paus tsis hloov cov muaj pes tsawg leeg ntawm cov ntaub ntawv uas twb muaj lawm nyob rau hauv lub hauv paus ntawm txhim kho nws cov kev ua tau zoo, yog li txhawm rau txhim kho kev siv thiab rov qab cov peev txheej. Nyob rau tib lub sijhawm, cov khoom siv tuaj yeem txhim kho, thiab tus nqi tuaj yeem raug txo kom txo tau qhov kev puas tsuaj rau ib puag ncig, uas tsis muaj kev ntseeg tau muab txoj hauv kev zoo los daws cov teeb meem loj zuj zus thiab ib puag ncig. Yog li cov kev tshawb fawb ntawm cov ntaub ntawv cryogenic kho yuav dhau los ua ib qho kev tshawb fawb tseem ceeb ntawm cov ntaub ntawv tshawb fawb cov neeg ua haujlwm hauv tsev thiab txawv teb chaws, tab sis kev ruaj ntseg ntawm cov kev tshawb fawb uas twb muaj lawm ob qho tib si hauv cov txheej txheem kho cryogenic thiab cov txheej txheem ntawm kev ua ntawm qee cov ntaub ntawv tshawb fawb tseem muaj ntau yam tsis txaus, rau loj-scale thiab daim ntawv thov ntawm cryogenic kho nyob rau hauv industrial coj obstacles, Yog li ntawd, kev txhim kho thiab kev tshawb fawb ntawm ruaj khov cryogenic txheej txheem system thiab cryogenic kho mechanism ntawm non-ferrous hlau yuav yog lub hom phiaj ntawm kev tshawb fawb nyob rau hauv daim teb no. Valve qauv npaj txoj kev: Qhov no STANDARD SPECIFIS LUB REPRESENTATION METHOD ntawm tus qauv NUMBER, HOM CODE, DRIVE MODE CODE, CONNECTION FORM CODE, STRUCTURE FORM CODE, sealing nto MATERIAL CODE, VALVE lub cev MATERIAL CODE thiab PRESSURE CODE.
