Siab radial cact thiab txuas ntxiv ncej yog cov neeg tua neeg ntawm bearings {}} Yog tias qhov no yog qhov xwm txheej tsis txaus ntseeg .
Piv txwv, txoj hlua khi khoov ntawm 3600 RPM khoov 7200 zaug hauv ib feeb kev sib cuag thiab cov kua dej siab yuav tsum muaj rau kev ua haujlwm kom tsim nyog rau kev ua haujlwm kom tsim nyog.
2.} lubrication paug
Rau bearings, tshaj 85% ntawm cov kabmob tsis ua tiav yog tshwm sim los ntawm kev nkag teb chaws, lossis dej tsis tau ntev li 250 1} {}.
Cov kev pabcuam lub neej yog qhov tseem ceeb .}} ki}} ki}} kis caug ib xyoo {}}
3.}} inhalation siab
Lwm yam tseem ceeb uas cuam tshuam rau kev coj tus kheej suav nrog kev tsav tsheb sib kho, thiab qee qhov ntsuas ntawm cov raj xa dej .
Rau Ib Leeg-theem Kab Rov Tav Cov Twj, Lub Axis quab yuam ntawm lub rotor yog qhia rau lub zog thawb, yog li txo nws lub neej kev pab cuam {}} cov cuab yeej siv ua ntu zus
Lub misalignment ntawm lub twj tso kua mis thiab cov khoom siv tsav ua rau muaj kev cuam tshuam nrog cov kabmob radial yog qhov ua rau muaj qee yam ntawm cov kabmob lossis cov teeb meem ntawm peb mus rau tsib lub hlis ntawm kev ua haujlwm; Txawm li cas los xij, tsis pub dhau ib qho kev sib txawv ntawm 0.025mm, tib lub twj tso kua mis yuav ua haujlwm ntau dua 90 lub hlis.
{{0 {}} pipeline lim
Pipeline Lim yog tshwm sim los ntawm kev tsis zoo ntawm kev nqus / cov twj tso kua mis tau yooj yim hloov cov kabmob muaj zog, lossis lawv cov kabmob tsis zoo tuaj yeem ua rau muaj kev ntxhov siab / lossis tsis zoo rau lwm cov kabmob hauv.
6.} cov yam ntxwv
Cov yam ntxwv ntawm pH, thiab cov khoom siv tshwj xeeb yog cov khoom siv ua kom muaj zog, yog tias cov khoom siv tsis zoo, thiab cov khoom siv tsis zoo, thiab cov khoom siv tsis zoo, .
7.} kev pab
Qhov mob hnyav ntawm kev pabcuam yog lwm qhov tseem ceeb, lub taub dej pib li cas hauv lub sijhawm? Piv txwv, lub twj tso kua mis uas pib thiab nres txhua ob peb vib nas this muaj ntau dua cov hnav khaub ncaws uas sau tsis tu ncua nyob rau hauv tib qho kev mob {}}
Raws li tib qho kev mob, submerged suction twj yuav ua haujlwm ntxiv rau kev txhawb nqa cov pa roj {0} .
8. net net lub taub hau
