Thaum cov bearings ua haujlwm, ntau lossis tsawg dua lawv yuav ua rau qee qhov kev puas tsuaj thiab hnav vim kev sib txhuam, tshwj xeeb tshaj yog thaum ua haujlwm ntawm qhov kub thiab txias, thiab txawm tias lub tawb bearings yuav puas. cov theem sib txawv, yog li cov kabmob tawb yuav tsum muaj cov yam ntxwv ntawm cov thermal conductivity zoo thiab kev sib txhuam me me, thiaj li txo qhov kev puas tsuaj ntawm cov kabmob.

Cov hauv qab no yog plaub theem ntawmbearing tawbkev puas tsuaj los koom nrog koj.Cia peb saib.

Ua ntej

Ntawd yog, lub budding theem ntawm cov kabmob tsis ua haujlwm pib, thaum qhov kub thiab txias, lub suab nrov yog qhov qub, tag nrho cov kev vibration ceev thiab cov zaus spectrum yog ib txwm, tab sis tag nrho cov ncov lub zog thiab cov zaus spectrum muaj cov cim qhia, uas qhia txog qhov pib ntawm lub sijhawm. bearing tsis ua hauj lwm.Lub sij hawm no, qhov tseeb bearing txhaum zaus tshwm nyob rau hauv lub ultrasonic seem nyob rau hauv lub cheeb tsam ntawm 20-60kHz.

Thib ob

Qhov kub thiab txias yog qhov qub, lub suab nrov me ntsis ntxiv, thiab tag nrho cov kev vibration tshaj tawm tau nce me ntsis.Qhov kev hloov ntawm kev vibration spectrum tsis pom tseeb, tab sis lub zog siab tshaj plaws tau nce ntau, thiab cov spectrum kuj tseem ceeb dua.Lub sijhawm no, cov kabmob tsis ua haujlwm tshwm sim nyob rau hauv thaj tsam ntawm 500Hz-2KHz.

Thib peb

Qhov kub thiab txias yog qhov qub, lub suab nrov me ntsis ntxiv, thiab tag nrho cov kev vibration tshaj tawm tau nce me ntsis.Qhov kev hloov ntawm kev vibration spectrum tsis pom tseeb, tab sis lub zog siab tshaj plaws yog nce ntau, thiab cov spectrum kuj tseem ceeb dua.Lub sijhawm no, cov kabmob tsis ua haujlwm tshwm sim nyob rau hauv thaj tsam li ntawm 500Hz-2KHz.Cov kabmob fault zaus, nws cov harmonics. thiab sidebands tuaj yeem pom meej meej hauv kev vibration velocity spectrum.Tsis tas li ntawd, lub suab nrov ntawm lub qab ntug nce siab hauv qhov kev vibration tshaj tawm spectrum, thiab tag nrho lub zog siab tshaj plaws yuav loj dua thiab cov spectrum tseem ceeb dua nyob rau theem thib ob.Lub sijhawm no, cov kabmob tsis ua haujlwm zaus tshwm sim hauv thaj tsam li 0-1kHz. .Nws raug nquahu kom hloov cov kabmob nyob rau hauv lub caij nyoog kawg ntawm theem thib peb, tom qab ntawd lub sijhawm no yuav tsum tau pom kev hnav thiab lwm yam kev coj tus kabmob ua txhaum.

Forth

Thaum qhov kub thiab txias nce ntau, lub suab nrov hloov pauv loj heev, tag nrho cov kev vibration tshaj tawm thiab kev vibration hloov pauv tau nce ntau, thiab cov bearing txhaum zaus pib ploj mus rau hauv kev vibration tshaj tawm spectrum thiab yog hloov los ntawm ib tug loj random broadband high-frequency suab nrov qab ntug. tag nrho cov nyiaj ncov lub zog nce sai thiab qee qhov kev hloov pauv tsis ruaj khov tuaj yeem tshwm sim.Bearings yuav tsum tsis txhob tso cai rau kev ua haujlwm hauv theem plaub ntawm kev txhim kho tsis ua haujlwm, txwv tsis pub muaj kev puas tsuaj loj tuaj yeem tshwm sim.

Plaub theem saum toj no yuav ua rau muaj kev puas tsuaj rau cov kabmob sib txawv.Qhov tseeb, tseem yuav muaj ntau yam teeb meem uas tsis tuaj yeem tiv thaiv hauv peb txoj haujlwm niaj hnub, vim tias nws tau hais tias cov neeg ua haujlwm cuam tshuam yuav tsum hloov lub tawb nqa khoom thaum cov teeb meem tau muab faib ua peb theem, kom tsis txhob muaj qhov ua tsis tiav loj dua.
