Indentation chaw hloov txoj kev ntawm microhardness tester
Lub tshuab microhardness tester yog qhov yooj yim rau kev khiav lag luam thiab txhim khu kev qha, thiab nws tau siv dav hauv Suav. Tab sis kev ua haujlwm tsis raug thiab kev siv, qhov kev poob ntsej muag feem ntau mob siab los ntawm lub chaw nruab nrab ntawm qhov chaw saib. Yog hais tias qhov kab nrig tseem nyob hauv qhov kev saib, nws tsis nyuaj rau kev kho lub chaw. Thaum qhov indentation deviates deb ntawm qhov chaw saib, nws yog qhov nyuaj rau tawv lub indentation los ntawm cov txheej txheem pa. Peb tau sau cov txheej txheem yooj yim nram qab no raws li kev paub dhau los ntawm lub xyoo, thiab cov txiaj ntsig tau zoo heev. Txawm hais tias qhov kev mob siab poob los ntawm lub nroog, qhov chaw hloov kho haujlwm tuaj yeem ua tiav hauv ib nrab ib teev.
1.Cov kauj ruam yooj yim
(1) Kho qhov trajectory ntawm theem ntawm txoj kev qhia kev tsheb nqaj hlau yuav tsum mus tib seem rau txoj kab txuas rau txoj kab hluav taws xob mus rau hauv qhov chaw nruab nrab saib;
(2) Hloov qhov kev tshawb nrhiav ob ntu ntawm kev tshawb ntawm qhov chaw kom pom mus rau ib qho kev tshawb nrhiav ib ntu nyob rau hauv cov kev qhia ntawm txoj kev tsheb nqaj hlau loj.
2.Txujci
(1) thawb theem mus rau sab xis, thiab tsuas yog thawb txiav theem ntawm cov lus qhia kev taw qhia kom ua cov kab sib chaws, thiab qhov kev ncua deb ntawm qhov uas nyob ib sab, uas yog, qhov txav ntawm theem mus rau sab laug txhua lub sijhawm yuav tsum yuav tsawg dua qhov pom Lub pob cheeb kom paub meej tias ntau tshaj li ob qhov kev nkag tau tuaj yeem tshwm sim hauv ib qho kev saib. Cov kev sib txuas ntawm cov kab nrig yog cov txav kev taug ntawm theem ntawm cov lus qhia kev tsheb nqaj hlau
(2) Thawb theem mus rau sab laug thiab daws qhov kev qhia kev tsheb nqaj hlau nrawm thiab sab laug thiab txoj cai txwv screws ntawm theem.
(3) Txav rov qab thiab rov qab thiab maj mam tig txoj kev qhia kev tsheb nqaj hlau los saib qhov chaw ntawm lub qhov siab siab txuas rau hauv txoj kab ntawm pom. Vim hais tias ntawm qhov indentation rau hauv txoj hlua ntev. Yog li ntawd, qhov nrhiav ob ntawm ib qho ntev txoj kev nrhiav tau yooj yim mus rau ib-seem kab nrhiav txoj kab txiav kom haum rau cov kev taw qhia kev txav ntawm cov lus qhia kev tsheb nqaj hlau. Txhim kho cov lus qhia kev tsheb nqaj hlau thaum kev nkag mus tau txuas mus rau kab rov tav kab rov tav ntawm thaj chaw saib.
(4) Ua rau lwm qhov kev poob qis thiab kho sab laug thiab txoj cai txwv screws ntawm theem kom txog thaum qhov poob ntsej muag nyob hauv qhov chaw nruab nrab ntawm qhov chaw saib, uas yog, pom ib qho ntev ib qho kev sib piv rau cov kev taw qhia kev tsheb nqaj hlau.
3.Kev piav qhia
(1) Thaum ua cov kev hloov kho saum toj no. Tsis txhob twist lub kab rov tav thiab ntsug txee ntu screws ntawm theem.
(2) Thaum ntseeg tau tias lub chaw thau khoom xoom xoom yog qhov kev ntseeg tau, nws raug nquahu kom thawb theem kom kos txoj kab tsis poob ntawm qhov kev thauj khoom tsawg kawg nkaus ntawm dej hiav txwv muag heev. Tom qab ntawd ua tiav kab hais txog kev pom thiab taw tes nrhiav cov kauj ruam.

Ob peb cov teeb meem nyob rau hauv kev siv ntawm cov qauv hardness block
1.Tau ob sab ntawm tus qauv hardness block?
Lawv feem ntau ua ntsuas' t ua haujlwm, tsuas yog hammering Brinell hardness block tuaj yeem siv ob sab. Thaum lub sij hawm ua khoom thiab qhov ntsuas ntawm lub hardness block, lub hom phiaj tseem ceeb yog kom ntseeg tau tias thaj chaw zoo thiab hardness uniformity ntawm ntsuas ntsuas. Yog li ntawd, qhov saum npoo ntawm kev ntsuas ntawm qhov ntsuas thiab qhov chaw txhawb nqa feem ntau sib txawv. Qhov ntsuas hluav taws xob ntawm lub hardness block tsuas yog ua tiav ntawm qhov ntsuas qhov ntsuas, thiab kev txhawb nqa Tsis tas yuav tsum muaj qhov nyuaj ntawm qhov nyuaj lossis qhov nyuaj qhov tsis yooj yim ntawm qhov chaw. Koj puas xav kom ntsuas lub hardness tester nrog qee yam tsis paub lossis tsis tsim nyog?
Feem ntau, sab tau cim nrog lub hardness txheem tus nqi yog ntsuas sab, thiab sab nrog ntsuas qhov ntsuas ntawm lub hammered Brinell hardness block (Brinell bar) kuj tseem ntsuas.
2.Kuv yuam kev lub hardness rau sab nraum qab!
Don' t ua tau zoo" tshawb nrhiav" yav tom ntej.
Yog tias koj tsis txhob' t tsoo ntau dhau, siv cov ntaub ntawv los ua kom cov pob ntsej muag saum npoo ntawm qhov chaw txhawb nqa los ntawm qhov nyuaj ntawm qhov tsoo tsis yog.
Nws ncaj qha siv rau kev txhawb nqa yam tsis sib tsoo. Ntawm ib txhais tes, lub chaw txhawb nqa tsis tuaj yeem sib raug zoo nrog lub rooj tshuaj ntsuam saum npoo (rau Rockwell hardness test, nws tuaj yeem ncaj qha ua rau muaj qhov ua yuam kev loj) cuam tshuam rau qhov ntsuas ntsuas qhov tseeb, ntawm qhov tod tes, nws yuav ua kev puas tsuaj ntawm lub rooj ntsuas saum npoo. Cov. Hmoov tsis zoo, qhov tsis zoo ntawm qhov indenter thaum lub sij hawm nias txheej txheem kuj tseem tuaj yeem ua kev puas tsuaj rau tus indenter.
3.Tau lub hardness block siv tau tom qab nws tas sij hawm?
Nws feem ntau tsis pom zoo kom siv cov khoom siv tawv tawv dhau, uas tsis txhais tau hais tias qhov hardness block tsis zoo. Ib yam li peb tsis noj cov zaub mov tas sijhawm, tsis tas vim tias cov khoom noj uas tas sijhawm yuav tsum muaj pwm.
Txawm li cas los xij, qhov nyuaj ntawm cov khoom siv muaj qee yam kev laus, uas yog, lub hardness yuav hloov dhau sijhawm. Txawm hais tias feem ntau ntawm cov tawv hardness uas tsim los ntawm cov lag luam raug cai tau dhau los ua khoom cuav thiab lub ntuj laus, qhov hloov pauv lub hardness tsis loj, tab sis nws yuav yooj yim dua rau siv tom qab rov lees paub raws li kev txheeb xyuas lub voj voog.
4.Qhov teeb meem ntawm lub hardness tus nqi ntawm lub hardness block
Thaum xaiv qhov ua kom tawv tawv, peb muaj lub hauv paus ntsiab lus: uas yog, ze li sai tau rau qhov nyuaj ntawm qhov kuaj ntsuas. Txawm li cas los xij, nws tsis yooj yim sua rau cov lag luam txheem hardness block kom npog tag nrho cov qib hardness. Hom no tsis tuaj yeem tsim. Ntawm qhov tod tes, cov txheej txheem txheej txheem tsis tuaj yeem ua tsis tau raws txheej txheem thiab cov qauv. Yog li ntawd, cov chaw tsim khoom lag luam ntawm cov hardness block feem ntau siv cov hardness block rau kev kuaj xyuas raws li kev cai hauv cov ntawv pov thawj kev cai. Cov uas muaj ntau lawm.
Yog tias koj muaj qhov xav tau tshwj xeeb, koj yuav tsum hu rau lub chaw lag luam hardness block kom nws. Ntawm chav kawm, tus nqi ntawm cov customized hardness block yuav siab dua, thiab qee qhov lawv yuav nyuaj rau kev tsim khoom, thiab lub voj voog tsim khoom yuav tsis luv.
Feem ntau qhov ntsuas hardness yog siv hauv kev lag luam. Tom qab qhov ntsuas qhov hardness tau ntsuas nrog lub hardness block ntawm cov pov thawj ntau, yuav tsis muaj teeb meem loj (lossis qhov tseeb yog qhov txaus) thaum ntsuas qhov nyuaj ntawm lwm yam.
5.Puas tuaj yeem siv lub hardness block yog tias nws xeb?
Yog hais tias lub xeb yog qhov hnyav, nws yuav tsum muab pov tseg. Nws yuav raug siv yog tias nws tsuas yog me ntsis xeb hauv zos.
Yog tias tsuas yog qhov chaw txhawb nqa yog xeb, tsuas yog xuab zeb nws thiab tshem nws.
Yog tias muaj xeb nyob hauv thaj chaw ntsuas, koj yuav tsum zam qhov ntsuas ntawm no. Txawm hais tias koj tshem tawm qhov xeb, thawj qhov chaw yuav tsis muaj nyob, thiab lub hardness ntawm chav kawm yuav txawv.
Hloov ntawm racking koj lub hlwb kom pom txoj kev daws teeb meem, nws yog qhov zoo dua los tiv thaiv nws ua ntej. Tom qab cov kab thaiv tawv tawv tau siv, nws yuav tsum tau rov ua dua nrog roj los tiv thaiv xeb lossis qhwv nrog cov ntawv los tiv thaiv xeb
