Lub khw Lavxias teb sab roj nplua nyeem tsis tu ncua ua rau muaj kev loj hlob tsis tu ncua. Nyob rau tib lub sijhawm, ib qho tseem ceeb ntawm kev hloov pauv poob rau ntawm cov khoom taw qhia rau kev lag luam kev lag luam nyob rau hauv cov xwm txheej ntawm qhov kub thiab txias hloov pauv thiab siab loads. Ib qho chaw tsim nyog nyob rau hauv ntu no yog nyob ntawm VMGZ roj (tawm-lub caij hydraulic thickened roj), uas, vim nws qhov tshwj xeeb muaj pes tsawg leeg, ua kom muaj kev ua haujlwm zoo ntawm cov khoom nruab nrog hydraulic drives hauv thaj tsam ntawm Far East, Siberia thiab Far. North.
Scope of application
Lub hom phiaj ntawm VMGZ yog qhov nruab nrab ua haujlwm rau cov tshuab hydraulic (cov twj hydraulic, hydraulic tswj, hydraulic drives) ntawm drilling rigs, nqa, tsheb, tshuab ua liaj ua teb, txiav thiab siv tshuab, khoom siv. Cov neeg tsim khoom pom zoo siv cov roj no hauv nruab nrab ntawm Russia ntawm qhov kub thiab txias (nws tau xav tias VMGZ hydraulic roj siv nyob rau hauv cov khoom siv sab nraum zoov) thiab cov cheeb tsam sab qaum teb (tsis hais lub caij nyoog twg).
Ib ob peb lo lus hais txog cov tuam txhab thiab thev naus laus zis
Ntawm cov tuam txhab lag luam Lavxias ua lag luam ntawm off-season hydraulic thickened roj, muaj plaub lub tuam txhab muaj npe nrov nrog lub koob npe nrov ua lag luam. Cov no yog Lukoil, Gazpromneft, Sintoil, TNK.
Raws li lub hauv paus rau yav tom ntej cov khoom kawg, cov roj xaiv zoo nrog cov ntsiab lus tsis tshua muaj leej faj, tau txais los ntawm kev siv cov roj av los yog cov dewaxing sib sib zog nqus. Xws li lub hauv paus yog tus cwj pwm los ntawm qhov tsawg kawg nkaus dynamic viscosity thiab qhov dej qis qis. Cov yam ntxwv ntawm kev ua haujlwm thiab lub cev physico-chemical uas VMGZ cov roj yuav tsum muaj yog muab los ntawm kev ntxiv cov khoom muaj txiaj ntsig zoo ntawm cov khoom siv ntxiv (tiv thaiv corrosion, tiv thaiv ua npuas ncauj, tiv thaiv hnav, antioxidant, thiab lwm yam).

txiaj ntsig
Los ntawm kev siv cov roj uas tsis yog lub caij ntuj no thickened hydraulic hauv kev ua haujlwm ntawm cov tshuab tshwj xeeb thiab khoom siv, cov neeg siv khoom tau txais lub sijhawm rau:
- tiv thaiv corrosion thiab txhua yam hnav qhov chaw ntawm hydraulic system;
- xyuas kom tsis muaj kev cuam tshuam ntawm cov khoom siv hauv qhov kub thiab txias (ntawm + 50 ° C txog - 40 ° C);
- pib lub hydraulic tsav, hla lub preheating theem;
- txo qis qhov xav tau ntawm cov roj hloov pauv (nrog rau lub caij nyoog) vim muaj tshuaj lom neeg thiab antioxidant stability ntawm VMGZ;
- zam qhov tsis tsim nyog ntawm cov kua dej ua haujlwm vim muaj cov khoom ua npuas ncauj thaum muaj kev ua haujlwm zoo ntawm cov cua txias thiab lubrication ntawm qhov chaw, uas yog ib qho tseem ceeb heev rau cov tshuab ceev ceev xws li hydraulic systems.
Vim li cas qhov khoom tseem ceeb?
VMGZ roj tsis zoo tuaj yeem ua rau muaj teeb meem ntau. Ntawm qhov tseem ceeb tshaj plaws, peb qhia txog qhov tsis zoo hauv qab no:
- nce kis kab mob ntawm hydraulic system;
- clogged lim;
- nce hnav thiab corrosion ntawm qhov chaw.
Vim li ntawd, cov khoom sivua tsis tiav ntxov, muaj kev pheej hmoo cuam tshuam nrog kev poob qis lossis kev ua haujlwm nres, thiab cov nqi kho mob nce ntxiv.
Yuav ua li cas xaiv cov khoom zoo?
Rau cov neeg siv khoom xws li VMGZ hydraulic roj, cov yam ntxwv ua lub luag haujlwm tseem ceeb. Txawm li cas los xij, cov khoom ntawm tib chav kawm muab los ntawm cov tuam txhab sib txawv ntawm cov roj nplua nyeem muaj kwv yees li tib yam kev ua haujlwm. Qhov tseeb no yog vim kev siv cov txheej txheem zoo sib xws ntawm cov additives. Nyob rau tib lub sijhawm, txhua lub tuam txhab, nrhiav kom muaj txoj haujlwm ruaj khov hauv kev sib tw hnyav, tso siab rau qee yam tseem ceeb ntawm cov khoom kawg. Piv txwv li, peb tuaj yeem tham txog kev tiv thaiv corrosion lossis qhov kub thiab txias (kev txwv tsis pub muaj hluav taws kub thiab hluav taws kub) ntsuas.
Yog li ntawd, cov cai uas yuav tsum tau ua raws thaum xaiv VMGZ roj tuaj yeem tsim raws li hauv qab no:
- Ua tib zoo kawm cov lus qhia txuas nrog, ua tib zoo saib xyuas cov khoom ua raws li cov qauv kev lees paub thoob ntiaj teb (ISO, SAE).
- Tsis txhob tsom mus rau ntu nqe xwb, lub hom phiaj yuav tsum yog tus txheej txheem txhais.
hmoov zoo nrog koj xaiv thiab tsis muaj teeb meem ua haujlwm ntawm koj cov cuab yeej!
