Valvesyog siv los ua tiav cov khoom sib cais huab cua hauv cov tshuab tshuaj, thiab feem ntau ntawm lawv cov sealing nto yog ua los ntawm stainless hlau.Nyob rau hauv cov txheej txheem sib tsoo, vim kev xaiv tsis raug ntawm cov ntaub ntawv sib tsoo thiab cov kev sib tsoo tsis raug, tsis yog tsuas yog cov khoom siv ntawm lub valve raug txo, tab sis kuj tseem cuam tshuam cov khoom zoo.Raws li cov yam ntxwv ntawm cov ntaub ntawv stainless hlau, peb tau xaiv lub zog siv zog thiab hnav tsis kam, thiab qhov zoo ntawm cov khoom tseem cuam tshuam tom qab cov khoom abrasive tawg hauv kev ua haujlwm.Nyob rau hauv xyoo tas los no, peb tau kawm cov ntaub ntawv abrasive uas nws cov formulations ntawm cov ntaub ntawv abrasive muaj peev xwm tswj tau lub sharpness, xws li dawb corundum thiab chromium oxide, xaiv cov cuab yeej abrasive thiab txoj kev abrasive, thiab lwm yam. Cov particle loj feem ntau xaiv w40, w14, w7. thiab W5, thiab lwm yam. Plaub yog tsim nyog.Los ntawm kev sim, nws tau raug txhawb nqa thiab siv rau hauv kev tsim khoom tiag tiag, uas tsis yog tsuas yog txhim kho qhov zoo ntawm qhov sealing nto, tab sis kuj txhim kho kev tsim khoom thiab tau txais txiaj ntsig zoo heev.
Rau lub valve rau grind lub workpiece, thawj zaug, cov cuab yeej sib tsoo yog embedded nrog xuab zeb, thiab tom qab ntawd kev sib tsoo yog tiav los ntawm kev sib tsoo ntawm cov khoom sib xyaw ntawm cov nplej thiab cov kua dej sib tsoo.Sib tsoo quab yuam yog hais txog lub zog ua haujlwm ntawm chav sib tsoo qhov chaw.Nws yog lub zog siv rau cov cuab yeej sib tsoo thiab ua haujlwm ntawm qhov chaw kom ua tiav los ntawm cov khoom abrasive.Yog tias qhov siab me dhau lawm, qhov sib tsoo cov nyhuv yuav me me, thiab lub siab yuav nce ntxiv.Cov nyhuv sib tsoo yog txhim kho, thiab kev sib tsoo zoo dua.Txawm li cas los xij, thaum lub siab nce mus rau ib qho txiaj ntsig, saturation tshwm sim, thiab kev sib tsoo efficiency feem ntau ncav cuag tus nqi loj.Tom qab ntawd, yog tias qhov siab ntawm ib cheeb tsam tseem nce ntxiv, qhov ua tau zoo yuav txo qis dua.
Qhov no yog vim hais tias lub valve abrasive hais muaj qee qhov kev txwv ntawm kev ua haujlwm siab.Thaum tus nqi txwv no dhau lawm, lawv yuav raug crushed, ua rau cov abrasive hais finer thiab txo tus kheej-sib tsoo muaj peev xwm.Yog li ntawd, chav tsev siab yuav tsum tau txiav txim siab raws li lub zog thiab crushing yam ntxwv ntawm lub abrasive.Tom qab kev sim, feem ntau yuav tsum tau xaiv cov kev txwv nram qab no: ① Hauv kev sib tsoo ntxhib, rau cov dawb corundum abrasive, xaiv 0.2 txog 0.5 MPa.③ Thaum lub sij hawm sib tsoo zoo, xaiv 0.03 ~ 0.12MPa rau cov pob zeb dawb abrasive.
Kev sib tsoo ceev yog hais txog qhov sib txawv txav ceev ntawm cov cuab yeej sib tsoo ntawm qhov chaw ua haujlwm.Kev sib tsoo ceev yog ib qho tseem ceeb ntawm cov txheej txheem los tswj tus nqi ntawm cov seem tshem tawm, tshem tawm ceev thiab qhov zoo ntawm cov txheej txheem nto.Daim duab 2 yog ib qho kev sib raug zoo nkhaus ntawm workpiece loj tshem tawm, machined nto roughness thiab sib tsoo ceev.
Kev ua haujlwm ntawm cov cuab yeej sib tsoo thiab nws cov khoom sib tsoo cov cuab yeej yog txhawm rau txhim kho cov abrasive ib ntus thiab tau txais qee qhov kev sib tsoo, thiab hloov nws tus kheej geometric duab mus rau workpiece nyob rau hauv ib txoj kev.Yog li ntawd, cov khoom ntawm cov grind yuav tsum muaj qhov zoo embedding ntawm abrasive grains thiab lub sij hawm ntev tuav ntawm nws tus kheej geometric raug.Grey cam khwb cia hlau HT200 yog cov khoom siv zoo tshaj plaws rau kev sib tsoo.Nws cov qauv muaj cov cementite nyuaj thiab hnav-resistant, ferrite nrog zoo toughness thiab plasticity, thiab kuj muaj graphite, uas muaj cov nyhuv lubricating thiab yooj yim rau kev tsim thiab txheej txheem..
Thaum lub sij hawm sib tsoo yuav tsum tau kom tau raws li qhov teev saum npoo zoo tshaj lub sij hawm yuav tsum tau tshem tawm cov npoo.Kev sib tsoo ceev yuav tsum raug txo kom tsim nyog.Tom qab kev sim, cov kev ntsuas ceev hauv qab no yog qhov tsim nyog dua: ① Thaum lub sij hawm sib tsoo, qhov ceev rau kev sib tsoo cov cuab yeej lossis cov khoom ua haujlwm hauv av yog 20-50m / min.②Thaum lub valve nyob hauv kev sib tsoo zoo, qhov ceev ntawm cov cuab yeej sib tsoo los yog cov khoom ua haujlwm hauv av yog 6 ~ 12m / min.Kev xaiv ntawm tus nqi nto roughness Surface roughness yog ib qho ntawm cov cim tseem ceeb ntawm qhov zoo.Nws muaj kev cuam tshuam zoo rau kev ua haujlwm saum npoo.Nws muaj kev cuam tshuam ncaj qha rau ntawm qhov chaw abrasion, tiv tauj nruj thiab sealing kev ua tau zoo, thiab tib lub sijhawm cuam tshuam rau kev ua haujlwm thiab lub neej ntawm cov khoom.Thaum siv cov kev sib tsoo sib txawv thiab qhov ntau thiab tsawg, qhov roughness tiav los kuj txawv.
