Heavy workpiece
Cov tshuab nruab thiab cov khoom sib dhos tas mus li.
Kev sim nto ntawm qhov chaw me me hollow
Yuav tsum muaj cov ntaub ntawv tseem ceeb rau kev xeem
Kev txheeb xyuas cov ntaub ntawv hauv lub tsev khaws khoom ntawm cov khoom siv hlau
Kev soj ntsuam ceev ceev hauv ntau qhov ntau thiab ntau qhov ntsuas rau cov khoom ua haujlwm loj
Lub zog quotient yog hais nyob rau hauv lub hardness unit HL thiab yog xam los ntawm kev sib piv qhov cuam tshuam thiab rebound velocities ntawm lub cev cuam tshuam.Nws rebounds sai dua los ntawm cov qauv nyuaj dua los ntawm cov softer sawv daws yuav, ua rau ib tug ntau dua lub zog quotient uas yog txhais li 1000 × Vr / Vi.
HL = 1000 × Vr/ Vi
Qhov twg:
HL— Leeb hardness value
Vr - Rebound ceev ntawm lub cev cuam tshuam
Vi - Kev cuam tshuam nrawm ntawm lub cev cuam tshuam
Ua haujlwm kub: -10 ℃ ~ + 50 ℃ ;

1 Pib-Up
Nias lub hwj huam yuam sij kom pib lub twj paj nruag.Cov cuab yeej ces tuaj rau hauv hom kev ua haujlwm.
2 Chaw thau khoom
Thawb lub loading-tube downwards kom txog thaum muaj kev sib cuag.Tom qab ntawd cia nws maj mam rov qab mus rau qhov chaw pib lossis siv lwm txoj hauv kev txhawm rau txhawm rau cuam tshuam lub cev.
3 Localization
Nias cov khoom siv txhawb nqa lub nplhaib ruaj khov rau ntawm qhov chaw ntawm cov qauv, cov kev taw qhia cuam tshuam yuav tsum yog ntsug rau qhov chaw kuaj.
4 Kev sim
-Nias lub khawm tso tawm ntawm sab saum toj ntawm cov khoom cuam tshuam los kuaj.Cov qauv thiab cov khoom cuam tshuam nrog rau cov
tus neeg teb xov tooj txhua tus yuav tsum muaj kev ruaj ntseg tam sim no.Cov kev taw qhia kev txiav txim yuav tsum dhau lub axis ntawm cov khoom cuam tshuam.
-Txhua qhov chaw ntsuas ntawm cov qauv feem ntau xav tau 3 mus rau 5 zaug ntawm kev sim ua haujlwm.Qhov tshwm sim cov ntaub ntawv dispersion yuav tsum tsis txhob
ntau tshaj tus nqi ± 15HL.
-Qhov kev ncua deb ntawm ob lub ntsiab lus cuam tshuam lossis los ntawm qhov nruab nrab ntawm txhua qhov cuam tshuam taw tes rau ntawm ntug ntawm cov qauv kuaj
yuav tsum ua raws li kev cai ntawm Table 4-1.
-Yog xav tau qhov tseeb hloov dua siab tshiab los ntawm Leeb hardness tus nqi mus rau lwm yam hardness nqi, kev sib piv yog xav tau kom tau txais
hloov dua siab tshiab kev sib raug zoo rau cov khoom tshwj xeeb.Siv kev tshuaj xyuas tsim nyog Leeb hardness tester thiab sib xws
hardness tester los kuaj ntawm tib tus qauv feem.Rau txhua tus nqi hardness, txhua qhov ntsuas homogeneously 5
cov ntsiab lus ntawm Leeb hardness tus nqi nyob ib puag ncig ntawm ntau tshaj peb indentations uas xav tau kev hloov pauv hardness,
siv Leeb hardness arithmetic nruab nrab tus nqi thiab sib thooj hardness nruab nrab tus nqi raws li tus nqi sib txheeb
Feem ntau, ua rau tus kheej hardness contrastive nkhaus.Contrastive nkhaus yam tsawg kawg yuav tsum muaj peb pawg
cov ntaub ntawv sib txheeb.

5 Nyeem ntsuas tus nqi
Tom qab txhua qhov kev ua haujlwm cuam tshuam, LCD yuav tso saib tus nqi ntsuas tam sim no, lub sijhawm cuam tshuam ntxiv rau ib qho, lub buzzer yuav ceeb toom ntev npaum li cas yog tias qhov ntsuas tus nqi tsis nyob hauv qhov siv tau.Thaum ncav cuag lub sij hawm cuam tshuam presetting, lub buzzer yuav ceeb toom ib tug ntev howl.Tom qab 2 vib nas this, lub buzzer yuav ceeb toom ib tug luv luv howl, thiab tso saib qhov nruab nrab ntsuas tus nqi.
Tom qab cov cuab yeej cuam tshuam tau siv rau 1000 mus rau 2000 zaug, thov siv cov nylon txhuam uas tau muab los ntxuav cov raj qhia thiab qhov cuam tshuam lub cev.Ua raws li cov kauj ruam no thaum ntxuav lub raj qhia,
1.unscrew lub nplhaib txhawb nqa
2. tshem tawm lub cev cuam tshuam
3.spiral lub nylon txhuam nyob rau hauv counterclockwise kev coj mus rau hauv qab ntawm lub raj qhia thiab coj nws tawm rau 5 zaug
4.Nruab qhov cuam tshuam lub cev thiab lub nplhaib txhawb nqa thaum ua tiav.
Tso lub cev cuam tshuam tom qab siv.
Txhua lub roj nplua nyeem raug txwv nyob rau hauv cov khoom siv cuam tshuam.
