Lub luag haujlwm tseem ceeb ntawm kev txiav cov kua hauv cov txheej txheem machining
Raws li peb txhua tus paub, cov khoom tsim nyog tus nqi yog ib qho tseem ceeb qhia tias cov neeg kho tshuab kev lag luam tau them nyiaj rau, thiab nws kuj yog ib qho ntawm cov yam tseem ceeb uas cuam tshuam rau kev txhim kho kev lag luam. Kev saib xyuas cov cuab yeej yog ib qho tseem ceeb heev cuam tshuam rau cov khoom tsim nyog tus nqi. Tab sis qhov tseeb, cov tuam txhab machining feem ntau tsis quav ntsej qhov cuam tshuam ntawm lubrication ntawm cov khoom siv. Yog li ntawd, tsim nyog lubrication tau dhau los ua ib qho kev kawm yuam kev rau txhua lub tuam txhab machining.
Lub lubrication ntawm cov khoom siv tsis yog tsuas yog nyob rau ntawm lubricants. Raws li ib qho ntawm cov khoom siv tseem ceeb hauv cov txheej txheem machining, cov kua txiav kuj tseem cuam tshuam ncaj qha rau cov nyhuv lubrication ntawm cov khoom siv. Xaiv cov kua txiav zoo zoo pab txhim kho qhov tseeb ntawm machining thiab kev ua haujlwm ntawm cov khoom siv, yog li pab cov tuam txhab machining optimize cov khoom tsim nyog cov nqi thiab txhim khu kev sib tw.

Cov kua dej txiav muaj lub luag haujlwm ntawm lubrication, txias, tiv thaiv xeb thiab tu, thiab lwm yam, uas yuav pab txo qis kev hnav ntawm cov cuab yeej machining thiab txhim kho qhov tseeb ntawm qhov chaw machined. Feem ntau nws tuaj yeem npaj nrog cov dej kais dej rau kev siv. Yog li ntawd, mechanical processing enterprises thawj zaug yuav tsum tau ua kom paub qhov kev faib ua feem thiab concentration ntau ntawm cov tshuaj.

Kev daws teeb meem:

Rau kev txiav cov kua dej, cov roj-hauv-dej lub xeev yog qhov ruaj khov tshaj plaws. Qhov kev txiav txim proportioning yog txhaj dej ua ntej, tom qab ntawd ntxiv cov tshuaj thawj zaug ntawm kev txiav cov kua dej, thiab txuas ntxiv ua kom tag nrho. Qhov kev xa tawm feem ntau yog 1:20=5 feem pua ​​,

Kho qhov ceev:

Thaum cov concentration ntawm cov tshuaj nce los yog txo, nws yog ib qho tsim nyog yuav tau ntxiv cov tshuaj diluted los kho cov concentration. Tsis txhob ntxiv dej ncaj qha mus rau qhov kev daws teeb meem siab, txwv tsis pub cov dej-hauv-roj tshwm sim yuav tshwm sim thiab cov tshuaj yuav nyob rau hauv lub xeev tsis ruaj khov. Txoj kev raug yog ntxiv 1 feem pua ​​​​ diluent mus rau qhov kev daws teeb meem siab, lossis ntxiv 6 feem pua ​​​​dluent mus rau qhov kev daws teeb meem tsawg, thiab kho cov concentration kom tswj tau qhov zoo tshaj plaws concentration ntawm 5 feem pua.

Tsis tas li ntawd, cov neeg siv yuav tsum tau xyuam xim rau plaub lub ntsiab lus hauv qab no thaum siv thiab tswj cov kua dej txiav:

1. Ua npaws
Feem ntau cov neeg saib xyuas lubrication npaj cov kua dej ncaj qha los ntawm cov kais dej. Lub hardness ntawm kais dej yog mos, thiab cov tshuaj yog ib qho yooj yim mus ua npuas ncauj thaum ntsib concentration deviation. Tsuav qhov concentration yog tswj ntawm 5 feem pua, qhov teeb meem foaming tuaj yeem daws tau yooj yim.

2. Roj slick
Roj slicks feem ntau yog los ntawm ob qhov chaw. Ib qho yog tias cov ntawv qhia kev tsheb ciav hlau cov roj txau tsis tu ncua thaum lub tshuab khiav yog txau los ntawm cov tshuaj ua kua thiab tom qab ntawd ntws mus rau cov kua tshuaj tank; lwm yam yog cov roj to ntawm cov spindle thiab cov cuab yeej hloov hydraulic system. Cov roj tau yooj yim emulsified vim qhov sib ntxiv ntawm emulsifiers rau txiav cov kua. Yog li ntawd, ib zaug ib tug roj slick tshwm, nws yuav tsum tau muab tshem tawm nyob rau hauv lub sij hawm. Cov cuab yeej zoo tshaj plaws yog cov roj skimmer, tab sis lub hnab nqus tuaj yeem siv tau.

3. Qhov tsw
Thaum cov roj slicks npog saum npoo ntawm cov tshuaj, cov tshuaj yuav tshaib plab ntawm oxygen. Cov kab mob anaerobic ua haujlwm heev nyob rau hauv nruab nrab qhov kub thiab txias tsis muaj oxygen. Thaum cov kab mob anaerobic decompose roj kom tau cov zaub mov, lawv yuav tso cov roj hydrogen sulfide, uas yog tshuaj lom thiab txaus ntshai rau tib neeg lub cev. Tsis tas li ntawd, cov kab mob anaerobic yog rhiab heev rau pH. Qhov zoo tshaj pH tus nqi rau cov kab mob anaerobic yog li 6.8-8.5, thiab cov tshuaj concentration yog li ntawm 2-2.5 feem pua ​​. Txhawm rau tiv thaiv kev ua haujlwm ntawm cov kab mob anaerobic, qhov concentration ntawm cov tshuaj yuav tsum khaws cia li ntawm 5 feem pua.

4. Kev ua xua ntawm daim tawv nqaij
Tus nqi pH uas tib neeg cov tawv nqaij tuaj yeem kov hovers nyob ib ncig ntawm 7. Ob qho tshuaj acidic thiab alkaline tuaj yeem ua rau tawv nqaij thiab ua xua. Cov neeg siv tau raug qhia kom ntxuav nrog xab npum lossis tshuaj ntxuav tes, zoo dua yog cov khoom tu tes, sai li sai tau tom qab sib cuag nrog cov kua dej.

Nyob rau hauv xyoo tas los no, lub teb chaws tau tawm tsam lub tswv yim ntawm kev txhim kho ntsuab, thiab qhia meej meej tias cov kua txiav yuav tsum tsis txhob muaj halogens xws li chlorine. Lub hauv paus ntsiab lus ntawm cov tshuaj no yog additives, thiab lawv txuas rau cov khoom kuj ua rau nws tsis yooj yim sua kom dhau ib puag ncig tiv thaiv ntawv pov thawj.
