Feem ntau hais lus, qhov kev co tsim tawm hauv cov txheej txheem sib tsoo yog ib qho teeb meem tshwm sim uas rhuav tshem ib txwm sib tsoo. Thaum kev sib tsoo nrawm siab thiab cov hlau sib tsoo yog loj, muaj zog co feem ntau tsim. Vim yog qhov tsis tsim nyog ntawm cov cuab yeej siv, lub log sib tsoo lub cev muaj zog tau teeb tsa rau ntawm cov kab zawv zawg me me, thiab qhov kev co uas tsim los ntawm lub cev muaj zog raug xa mus rau lub log sib tsoo los ntawm tus ncej me me. Hauv cov txheej txheem ntawm kev sib tsoo, kev txav chaw hla ntawm lub tsheb me me xa cov kev co mus rau cov menyuam los ntawm kev sib tsoo lub log, thiab cov menyuam pub rov qab qhov kev co mus rau cov kab ke me me, uas ntxiv ua rau muaj kev vibration ntawm tag nrho cov kab ke. Hauv cov txheej txheem ntawm kev sib tsoo, kev co tsim los ntawm cov txheej txheem ua haujlwm ncaj qha cuam tshuam rau qhov ua tau zoo thiab tsim khoom ntawm cov menyuam nto. Yog tias tsis muaj kev co thiab tshem tawm hauv lub sijhawm nyob rau hauv cov txheej txheem ntawm ib nrab kev sib tsoo thiab kev sib tsoo zoo, qhov saum npoo ntawm cov menyuam yuav tsum tau teeb tsa nrog cov duab plaub fab xwm txheej kev co.
Kev co qhov chaw ntawm cov zom zom feem ntau yog los ntawm cov hauv qab no:
(1) Qhov laj thawj tseem ceeb yog tias kev sib tsoo lub log tsav tsis sib luag thiab ua rau muaj kev co.
(2) Lub log sib tsoo tsis sib txig sib luag thiab zoo li qub thiab vibrates thaum nws tig.
(3) Qhov ntev lossis nruj ntawm V-txoj siv tsav tsis sib xws, ua rau muaj kev co.
(4) Kev co ua los ntawm kev sib tsoo tsis sib luag thiab cov tuab tuab tsis sib xws ntawm cov hlau sib tsoo txheej.
(5) Yog tias lub tshuab ua kom lub zog ua haujlwm tsis zoo, lossis lub lapping yog nyob rau hauv daim ntawv ntawm qhov taw tes lossis kab, kev co yuav tshwm sim.
Ib txoj hauv kev zoo los tshem tawm kev co
Muaj peb hom kev co. Txhawm rau tshem tawm qhov kev co hauv txheej txheem kev sib tsoo, peb yuav tsum pib los ntawm peb yam: sib tsoo, sib tsoo lub log, thiab ua haujlwm. Kev co ntawm cov txheej txheem ua haujlwm lossis tshuab zom tuaj yeem kawm los ntawm kev sib tsoo kuaj. Nyob rau tib lub sijhawm, cov txheej txheem sib tsoo tuaj yeem tswj tau los ntawm kev hloov cov txheej txheem txheej txheem (xws li kev sib tsoo tus nqi) uas muaj kev cuam tshuam rau cov txheej txheem sib tsoo, thiaj li txwv tsis pub tsim kev co.
Txoj hauv kev tshem tawm kev quab yuam
Txoj hauv kev zoo tshaj plaws los tshem tawm kev quab yuam yog nrhiav kom paub qhov cuam tshuam sab nraud (qhov chaw muaj kev co) thiab tshem nws tawm. Yog tias nws tsis tuaj yeem tshem tawm tau, txoj kev rho tawm tuaj yeem siv tau. Kev sib tsoo log tsav lub cev tau teeb tsa ntawm tus ncej me me. Txawm hais tias cov ntaub qhwv roj hmab tau teeb tsa nyob rau sab qis ntawm lub hauv paus lub cev (nce kev ua kom ntub), tsis muaj damping ntawm kev sib koom ua ke ntawm cov phaj hauv qab thiab phaj npog sab saud ntawm cov thav duab me me. Raws li qhov ntub dej me me dhau, qhov kev vibration tsis raug tshem tawm, thiab nws tseem ua rau ntawm lub tsheb me. Kev ntsuas kev txhim kho yog txhawm rau txhim kho cov roj hmab ncoo rau hauv qab phaj thiab phaj npog sab saud ntawm cov kab zawv zawg me kom sib npaug lub cev muaj zog kom raug. Hloov txoj siv txoj siv txoj hlua kom ntseeg tau tias nws nruj nruj thiab ntev zoo ib yam. Ib qho ntxiv, qhov sib txig sib luag thiab zoo li qub ntawm lub log sib tsoo tau hloov kho kom tshem tawm cov centrifugal quab yuam ua los ntawm kev sib hloov ceev.
Txoj hauv kev kom tshem tawm qhov kev txaus siab rau tus kheej
(1) xaiv qhov tsim nyog ntawm qhov tsis cuam tshuam nrog kev sib tsoo
Txoj hauv kev ua tau zoo yog txiav txim siab qhov sib tsoo los ntawm kev sim. Kev sib tsoo tuaj yeem raug kuaj raws li qhov pib xaiv qhov sib tsoo, thiab tom qab ntawd cov nyiaj sib tsoo tuaj yeem hloov kho kom txog thaum txiav txim siab thaum kawg. Hauv kev xyaum, kev co ntawm lub log tau pom raws li hauv qab no: thaum txoj kab nrawm V ntawm kev sib tsoo lub log yog nyob ntawm thaj tsam ntawm 5-15m / s, qhov kev co me me heev; thaum V nyob hauv thaj tsam ntawm 15-25m / s, qhov kev co pom tseeb, tab sis nws tseem ruaj khov; thaum V nyob ntawm thaj tsam 25-30m / s, qhov kev co muaj zog tuaj; thaum v=35m / s, qhov kev co hnyav heev. Yog li, raws li tus yam ntxwv tsis txaus ntseeg ntawm lub log sib tsoo, qhov nruab nrab thiab qis-nrawm sib tsoo yuav tsum raug xaiv kom deb li deb tau kom tsis txhob muaj kev txaus siab rau tus kheej. Feem ntau, 18-20m / S zoo dua. Raws li kev taug kev nrawm ntawm lub tsheb loj, qhov dav tau txo nrog qhov nce ntawm qhov nrawm. Thaum qhov nrawm qis dua 300 mm/min, qhov nce siab nce ntxiv. Yog li ntawd, nyob rau hauv qhov xwm txheej uas yuav tsum tau siv lub tshuab ua kom nruj, qhov tsim nyog pub tus nqi thiab 400-500mm / min rau kev sib tsoo ib nrab thiab kev sib tsoo zoo yuav tsum raug xaiv. Thiab kev hloov kho nrawm yog qhov zoo thaum nws nyob ze rau qhov kawg ntawm kev hloov pauv. Txwv tsis pub, thaum thim rov qab, qhov nrawm hloov pauv sai sai, uas yog ib qho yooj yim los tsim kev co. Tus neeg teb xov tooj feem ntau xaiv 10-14r / min thaum lub tshuab ua haujlwm nrawm nyob rau hauv ib nrab zoo sib tsoo thiab sib tsoo zoo. Raws li kev soj ntsuam hauv kev coj ua, nws yooj yim dua tshwm rau qhov kev hloov pauv thaum siv qis dua. Kev daws teeb meem yog ua qhov sib txawv. Thaum n> 18 rpm / min, qhov tshwm sim ntawm kev hla kev hla tuaj yeem zam tau zoo los ntawm kev txhim kho cov lej sib hloov ntawm cov khoom ua haujlwm hauv cov txheej txheem ntawm kev sib tsoo ib nrab thiab kev sib tsoo zoo.
(2) Hauv cov txheej txheem ntawm kev sib tsoo zoo ib nrab thiab kev sib tsoo zoo, cov kua txias nrog qhov ua kom siab ntawm cov kua sib tsoo zoo kuj tseem tuaj yeem ua tiav qhov txo qis kev co zoo.
(3) Lub log sib tsoo kom raug yog siv los txhim kho kev tiv thaiv kev vibration. Muaj peb hom tseem ceeb ntawm kev sib tsoo log: ceramic, cob, thiab roj hmab. Hais txog kev tiv thaiv kev ua haujlwm tsis zoo, roj hmab sib tsoo lub log muaj qhov pom tseeb tshaj plaws tiv thaiv kev co." Saint Gobain" sib tsoo log, 23a60-lb24 (750 × 100 × 305), tau sim tawm. Nws daim ntawv cog lus yog thermosetting roj hmab, thiab nws qhov kev tiv thaiv kev ua kom pom tseeb yog qhov zoo dua li ntawm cov khoom siv sib tsoo ceramic sib tsoo.
(4) txhim kho qhov tseeb qhov tseeb ntawm kev txhawb nqa
Qhov chaw nyob ntawm qhov kev txhawb nqa yob yog ob lub ntsej muag conical. Yog tias ob lub caj dab txhawb nqa tsis sib haum nrog lub chaw sib tsoo tshuab, qhov kev txhawb nqa yob yuav ua rau lub zog txav mus los thiab lub zog khiav tawm hauv cov txheej txheem ntawm kev sib hloov. Yog li, nws yuav tsum tau ua tib zoo ua ke txhawm rau txhim kho qhov tseeb. Ib qho ntxiv, nws yuav tsum tau sau tseg tias cov ntsia hlau hauv pem teb ntawm lub caj dab yuav tsum nruj tom qab ua kom sib haum thiab tso chaw. Yog tias qhov chaw tsis raug, qhov sib npaug thiab sib luag yuav tsis ua siab ntev hauv cov txheej txheem sib tsoo. Qhov phom sij yog tias lub zeb zeb yuav ua haujlwm tsis ruaj khov, cov tuab ntawm cov kab sib dhos yuav ua tsis sib xws, nthwv dej khoov, nkhaus thiab nkhaus nkhaus yuav tsis tsuas yog cuam tshuam loj heev rau cov khoom lag luam zoo, tab sis kuj txo qhov kev pab cuam lub neej ntawm cov menyuam dov cov menyuam thiab lwm yam qhov Yog li ntawd, nws yog qhov teeb meem uas tsis tuaj yeem tsis quav ntsej los tswj thiab txheeb xyuas qhov coaxiality ntawm lub cev yob thiab yob txoj kab nruab nrab thiab qhov sib npaug ntawm lub cev yob. Ib qho ntxiv, phau ntawv glycerine lubrication yog siv rau lub lubrication ntawm lub caj dab bracket, thiab cov roj nplua nyeem tsis zoo. Raws li qhov tshwm sim no, cov roj tso tsheb hlau luam tuaj yeem qhib rau hauv qab thiab sab vuas ntawm lub caj dab ncej kom ua rau lub tshuab ua kom tsis tu ncua thiab cov roj zaj duab xis zoo ib yam, thiaj li ua kom ntseeg tau ruaj khov ntawm kev txhawb nqa cov menyuam. Hauv cov txheej txheem ntawm ib nrab kev sib tsoo thiab kev sib tsoo zoo, vim tias qhov ntsuas ntsuas feem ntau nres, thiab thaum rov ua haujlwm dua tom qab ntsuas, qhov sib npaug zoo tsim los yav dhau los yuav raug hloov pauv vim lub zog pib tam sim. Yog li ntawd, nws yog qhov zoo dua los ntsuas cov menyuam ntawm qhov nrawm uas tsis tas siv lub sijhawm sib tsoo zoo. Lossis qeeb thiab pib zoo ib yam yuav tsum tau txais thaum lub sijhawm rov pib ua haujlwm txhawm rau tiv thaiv kev cuam tshuam thiab xyuas kom muaj kev sib npaug sib luag tsis hloov pauv. Ntxiv mus, tom qab 2-3 dhau ntawm kev ua tiav ib nrab ua tiav, qhov ruaj khov sib tsoo nto tuaj yeem tau txais.
