Siv cov cuab yeej tshwj xeeb rau kev teeb tsa thiab tshem tawm
Cov cuab yeej txhim kho qib siab tuaj yeem zam kev puas tsuaj los ntawm cov cuab yeej tsis raug thiab kev ua haujlwm thaum lub sijhawm teeb tsa. Piv txwv li, thaum txhim kho cov kabmob, cov neeg ua haujlwm tau siv txoj kev sib tsoo tooj liab, uas yog ib qho yooj yim ua rau lub zog tsis sib xws ntawm cov kabmob, ua rau deformation ntawm lub tawb, kev puas tsuaj rau cov khoom dov, thiab kev tshem tawm loj. Cov hmoov tooj liab ya mus rau hauv lub tawb nqa khoom, uas yooj yim ua rau cov kabmob tsis ua haujlwm.
Txheeb xyuas cov kabmob ua ntej kev teeb tsa
Rau cov bearings qub, kos lub pob (kem) nto rau burrs, khawb, tawg. Txawm hais tias qhov radial clearance thiab axial clearance ntawm lub qub bearing yog tsim nyog, feem ntau tsuas yog ntsuas radial clearance. Rau cov kabmob tshiab, ua ntej xyuas tias cov kabmob muaj tseeb. Xa mus rau Table 1 rau cov qauv radial clearance ntawm dov bearings. Piv txwv li: Qauv 6318 sib sib zog nqus groove pob bearing, lub puab kab ntawm cov kabmob yog 90mm, radial clearance range yog 0.0}16 ~ 0.046mm, thiab qhov siab tshaj plaws hnav tus nqi ntawm cov kabmob kuj tuaj yeem pom tias yog 0.25mm
.
Txheeb xyuas qhov sib txuam qhov ntev ntawm cov kabmob thiab lub rotor ncej
Thaum sib sau ua ke lub cev muaj zog, nws tseem yuav tsum tau ua tib zoo xyuas qhov sib txuam ntawm cov kabmob thiab lub rotor ncej thaum cov kabmob raug teeb tsa (Table 2), thiab qhov sib txuam loj ntawm cov kabmob sab nraud thiab qhov kawg npog qhov.
Tswj kom muaj nuj nqis ntawm cov kabmob thiab cov kabmob chamber roj
Cov roj ntau dhau ntawm cov kabmob thiab lub thawv yuav ua rau cov kabmob dov lub cev plam, ua rau cov khoom siv dov hloov los ntawm kev sib txhuam ntawm kev sib txhuam mus rau kev sib txhuam, thiab kev puas tsuaj rau cov kabmob dov. Thaum nws nce, cov qib roj yuav txo qis, lub lubricating roj zaj duab xis ntawm cov khoom dov ua thinner, thiab lub lubrication mob tsis zoo, uas yooj yim ua rau lub suab nrov txawv txav ntawm cov kabmob, plam ntawm qhov chaw, thiab ua rau lub neej luv. bearing. Feem ntau, muaj cov roj chamber nyob rau sab ntawm lub cav kawg npog (tshwj tsis yog rau cov motors tsim nrog ob-sealed bearings). Raws li qhov ceev ntawm lub cev muaj zog, cov roj uas tuaj yeem ntim rau hauv cov kabmob chamber tuaj yeem ua raws li cov qauv hauv qab no: thaum lub cev muaj zog tsawg dua 1500r / min, cov roj ntxiv yog cov kabmob chamber. 2/3 ntawm qhov ntim. Thaum qhov ceev ntawm 1500 thiab 3000r / min, nws yog 1/2 ntawm cov kabmob chamber ntim. Thaum qhov ceev tshaj 3000r / min, nws yuav tsum tsawg dua los yog sib npaug rau 1/3 ntawm cov kabmob ntim. Hauv cov txheej txheem ua haujlwm tiag tiag, rau cov bearings khiav ntawm qhov kub thiab kub ceev, cov bearings nrog sealing nto yuav tsum tau siv tsawg li sai tau, lub peev xwm ntawm cov roj cia ntawm lub cav roj yuav tsum tau nce, thiab cov roj nozzles yuav tsum tau muab tso rau. los txhim kho lub neej ua haujlwm ntawm lub cev muaj zog bearings.
