I. Hloov lub nruas tam sim yog tias muaj qee yam hauv qab no tshwm sim:
1. Cov qauv kev puas tsuaj tsis tuaj yeem hloov tau
Los ntawm -los ntawm cov kab nrib pleb lossis deformation ntawm lub nruas nto, tshwj xeeb tshaj yog cov kab nrib pleb los yog tawg ntawm cov khoom siv hauv paus; txawm tias kev kho vuam hauv zos tsis zoo li yuav rov qab muaj zog tag nrho.
Kev cuam tshuam loj ntawm lub nruas roundness (radial runout> 1mm), ua rau tsis sib xws thiab tsis zoo ntawm lub tshuab vibration.
2. Kev puas tsuaj sab hauv rau cov eccentric blocks lossis vibration system
Kev hnav hnyav ntawm eccentric ncej bearings, xoob lossis tawg eccentric thaiv kev kho bolts, ua rau txo qis excitation quab yuam lossis qhov chaw ntawm lub ntiajteb txawj nqus hloov.
Nquag deterioration thiab blackening ntawm cov iav roj nyob rau hauv lub vibration chamber, nrog rau kub kub, qhia nyob rau hauv lub bearing lubrication tsis ua hauj lwm thiab irreversible puas.
3. Vibration damping system tsis ua hauj lwm thiab irreparable puas
Kev laus, hardening, los yog tawg ntawm cov roj hmab damping blocks, los yog txawv txav nruj ntawm lub pob khawm, ua rau tsis sib npaug vibration zog kis tau tus mob thiab lub tshuab loj vibration.
Yog tias hloov cov khoom damping tsis txhim kho kev vibration stability, nws qhia tau hais tias kev laus ntawm lub nruas sib dhos.
II. Kev ntsuam xyuas kom txiav txim siab seb qhov Kev Hloov Pauv yog los txog
1. Hnav kom ze rau tus qauv txwv
Raws li cov qauv kev lag luam, cov khoom hnav tshaj 80% ntawm "tsim hnav" yog suav tias yog tsis tsim nyog.
Ultrasonic thickness ntsuas ntawm lub nruas phab ntsa yog pom zoo. Yog hais tias lub zos thinning tshaj 30% ntawm thawj thickness, muaj kev nyab xeeb kev nyab xeeb.
2. Tsis tu ncua kev vibration Performance
Tsis ruaj tsis khov kev co zaus thiab hloov pauv amplitude, tom qab txiav txim tawm cov teeb meem hydraulic system, qhia txog cov qauv hauv lub nruas.
Nyuaj pib kev co lossis tsuas yog ua tiav ib qho - theem amplitude (tsuas yog qhov loj lossis me me vibrations) yuav qhia tau tias muaj kev puas tsuaj los yog lub cev muaj zog, tab sis kuj tuaj yeem tshwm sim los ntawm lub nruas load imbalance.
3. Cov nqi kho ntau zaus tshaj qhov hloov pauv
Yog tias cov ntsaws ruaj ruaj, bearings, thiab kev vibration dampers tau hloov ntau zaus hauv rau lub hlis dhau los, thiab qhov teeb meem rov tshwm sim, lub nruas lub neej yog ze rau qhov kawg.
Thaum tus nqi kho tag nrho tshaj li 60% ntawm tus nqi ntawm lub nruas tshiab, kev hloov ncaj qha raug pom zoo.
III. Cov lus pom zoo soj ntsuam txhua hnub: Kev kuaj pom ntxov thiab kev cuam tshuam
Txheeb xyuas qhov nruj ntawm eccentric thaiv bolts txhua 200 teev ua haujlwm.
Ntxuav lub hydraulic roj lim caij txhua hli thiab xyuas cov roj turbidity los tiv thaiv impurities los ntawm kev nkag mus rau hauv kev co.
Ua tib zoo saib xyuas tshwj xeeb rau kev sib khi ntawm lub thawv hluav taws xob thaum lub caij los nag los tiv thaiv kev ua haujlwm tsis sib xws los ntawm kev ya raws hauv cov tswj module.
Tsis tu ncua saib xyuas qhov kev vibration waveform ntawm steel log siv lub vibration analyzer thiab tsim cov ntaub ntawv kho mob rau cov khoom siv.
