Yuav Ua Li Cas Ntsuas Qhov Hardness Ntawm Tooj Nozzle

Taw qhia:

Copper faucets, tseem hu ua dej nozzles los yog ceev-txuas cov kais dej hauv ntau qhov kev lag luam, yog cov khoom tseem ceeb hauv cov tshuab dej.

Kev ntsuam xyuas lub hardness ntawm tooj liab nozzle los xyuas kom meej tias nws tsis cuam tshuam rau deformation thaum siv yuav ua tau nyob rau hauv ntau txoj kev:

Nkag siab tus qauv hardness ntawm tooj liab nozzle

Tus qauv hardness ntawm tooj liab nozzle yuav txawv nyob ntawm seb lub hauv paus chiv keeb, kev lag luam thiab cov khoom tshwj xeeb. Hauv Suav teb tus qauv, qhov nyuaj ntawm tooj liab feem ntau ntsuas los ntawm Brinell hardness (HB) txoj kev sim, thiab qib hardness yog txiav txim siab raws li qhov deformation degree los ntawm lub zog ntawm cov tooj liab. Tsis tas li ntawd, Rockwell hardness (HRB, HRC) kuj yog ib qho kev siv hardness standard. Tus nqi hardness tshwj xeeb yuav tsum xa mus rau cov qauv kev lag luam hauv lub tebchaws lossis cov qauv kev lag luam, xws li qib tooj liab hardness thiab tus nqi HB uas tau teev tseg hauv Suav teb tus qauv.

Siv cov txheej txheem hardness kuaj kom tsim nyog

Brinell hardness xeem:

Siv Brinell hardness tester, lub pob steel ntawm ib txoj kab uas hla yog nias rau hauv qhov chaw ntawm cov tooj liab nozzle nyob rau hauv lub siab, thiab lub cheeb los yog qhov tob ntawm indentation yog ntsuas los txiav txim tus nqi hardness.
Txoj kev no yog tsim rau cov ntaub ntawv loj, hnyav, tab sis yuav tsis haum rau cov kais dej me me los yog nyias nyias.

Rockwell hardness xeem:

Rockwell hardness test suav nrog HRB thiab HRC nplai, uas tsim nyog rau cov khoom sib txawv hardness.
Thaum lub sij hawm qhov kev xeem, lub pob zeb diamond los yog steel pob indenter ntawm ib tug tshwj xeeb cov duab yog nias rau hauv qhov chaw ntawm lub tooj liab nozzle ntawm ib tug tshwj xeeb siab, qhov tob los yog txoj kab uas hla ntawm indentation yog ntsuas, thiab hardness tus nqi yog txiav txim raws li ib tug txheej txheem rooj.
Rockwell hardness test yog dav siv nyob rau hauv industrial ntau lawm vim nws ceev thiab simplicity.

Vickers Hardness Test:

Vickers hardness test, tseem hu ua pob zeb diamond pyramid hardness test, yog tsim rau micro-indentation hardness kuaj.
Thaum kuaj, lub pob zeb diamond indenter yog siv los tsim cov square indentation ntawm cov khoom siv, kab pheeb ces kaum ntev ntawm qhov indentation yog ntsuas, thiab tus nqi hardness yog xam raws li tus qauv.
Txoj kev no muaj qhov siab precision, tab sis kev ua haujlwm yog qhov nyuaj.

Xav txog lwm yam uas cuam tshuam rau hardness

• Alloy muaj pes tsawg leeg: Cov alloy muaj pes tsawg leeg ntawm tooj liab nozzle yuav ncaj qha cuam tshuam nws hardness. Qhov sib ntxiv ntawm cov ntsiab lus sib txawv thiab cov proportions tuaj yeem hloov pauv lub cev thiab tshuaj lom neeg ntawm cov khoom, yog li cuam tshuam rau hardness.
• Cov txheej txheem kev kho cua sov: lub hardness thiab lwm yam khoom siv ntawm cov tooj liab nozzle tuaj yeem hloov kho los ntawm annealing, quenching thiab lwm yam kev kho cua sov. Kev kho cua sov kom zoo tuaj yeem txhim kho hardness thiab hnav tsis kam ntawm cov khoom.
• Kev kho deg: Qee cov txheej txheem kho saum npoo (xws li electroplating, txau, thiab lwm yam) tuaj yeem tsim cov yeeb yaj kiab tiv thaiv ntawm lub ntsej muag tooj liab txhawm rau txhim kho corrosion thiab hardness. Txawm li cas los xij, nws tseem ceeb heev uas yuav tsum nco ntsoov tias cov kev kho mob no tuaj yeem hloov pauv tus nqi hardness qub ntawm cov khoom.

Kev ntsuam xyuas hauv kev siv tswv yim

• Nrog rau cov khoom siv phau ntawv: nkag siab txog tooj liab nozzle chaw tsim khoom, cov khoom siv, txheej txheem kev kho cua sov thiab cov qauv hardness thiab lwm yam ntaub ntawv.
• Kev sim ua piv txwv: Yog tias muaj kev tso cai, qhov kev sim hardness ntawm tus qauv tooj liab nozzle tuaj yeem ua tiav los xyuas seb nws puas ua tau raws li cov qauv tsim nyog thiab siv tau.
• Daim ntawv tshaj tawm kev soj ntsuam zoo: Tus neeg muag khoom yuav tsum tau muab daim ntawv tshaj tawm kev tshuaj xyuas cov khoom lag luam tawm los ntawm lub koom haum thib peb qhov kev soj ntsuam zoo kom paub meej tias qhov hardness thiab lwm yam kev ua tau zoo ntawm tooj liab nozzle ua tau raws li qhov yuav tsum tau ua.

Txhawm rau ua kom tiav, kev ntsuam xyuas ntawm qhov nyuaj ntawm lub taub dej tooj liab yuav tsum xav txog ntau yam thiab txoj hauv kev los xyuas kom meej tias nws tsis yooj yim rau deform thaum siv thiab ua tau raws li cov qauv thiab cov kev cai.
