Puas muaj qhov yuav tsum tau ua rau qhov chaw ua haujlwm kub ntawm lub diaphragm siab ntsuas?
Lub diaphragm siab ntsuas qhov tseeb muaj qee qhov kev xav tau ntawm qhov kub ntawm qhov chaw ua haujlwm thaum lub sijhawm ua haujlwm. Yog hais tias lub diaphragm siab ntsuas yog siv nyob rau hauv ib qho chaw uas kub heev, nws kuj yuav muaj ib co phem phem. Yog li txhua tus thawj zaug xav seb qhov ntsuas kub ntawm lub diaphragm siab npaum li cas tuaj yeem tiv taus. Yog li dab tsi yog qhov kub-resistant kub ntawm lub diaphragm siab ntsuas?
Nyob rau hauv cov qauv ntawm ntau yam diaphragm siab gauges nyob rau hauv peb lub teb chaws, feem ntau tsuas yog ib txwm ua hauj lwm qhov kub thiab txias ntawm lub diaphragm siab ntsuas. Piv txwv li, lub diaphragm siab ntsuas yog -40-70 degrees, thiab lub diaphragm siab ntsuas yog -25-55 degrees, tab sis tsis muaj kev cai. Qhov kub-resistant kub.
Txawm hais tias muaj cov diaphragm siab ntsuas cov chaw tsim khoom uas tsim cov cua kub-resistant diaphragm siab gauges los yog high-temperature diaphragm siab gauges, ob peb manufacturers ntawm diaphragm siab gauges qhia meej txog qhov kub-resistant kub los yog high-temperature kub ntawm diaphragm siab gauges. Qhov no kuj ua rau cov neeg siv cov diaphragm siab ntsuas qhov txaj muag.
Dab tsi yog qhov kev khiav hauj lwm kub ntawm qhov hu ua kub-resistant diaphragm siab ntsuas los yog stainless hlau high-temperature resistant diaphragm siab ntsuas? Puas yog qhov chaw ua haujlwm lossis qhov ntsuas kub nruab nrab?
Ntawm no peb yuav tsum xub nkag siab qhov ntsuas kub ntawm ntau yam stainless hlau diaphragm siab ntsuas lub caij nplooj ntoo hlav thaum vuam, lawv yog:
Brazing (tin soldering), qhov kub yog 120 degrees thaum lub sij hawm vuam, thiab feem ntau yog siv rau welding tooj liab pob qij txha thiab tooj liab caij nplooj ntoos hlav raj.
Nyiaj vuam, nrog rau qhov kub ntawm 600 degrees thaum vuam, feem ntau yog siv rau vuam tooj liab pob qij txha thiab stainless hlau caij nplooj ntoos hlav raj.
Argon arc vuam, vuam kub yog 1500 degrees, feem ntau yog siv rau vuam steel pob qij txha thiab stainless hlau caij nplooj ntoos hlav raj.
Yog li feem ntau, tsuav koj paub txoj kev vuam ntawm lub caij nplooj ntoos hlav raj ntawm lub diaphragm siab ntsuas, koj tuaj yeem paub qhov kub thiab txias uas lub diaphragm siab ntsuas tuaj yeem tiv taus, uas yog: brazed diaphragm siab ntsuas tuaj yeem ua haujlwm ib txwm qis dua 120. degrees, nyiaj vuam hom diaphragm siab gauge tuaj yeem ua haujlwm ib txwm qis dua 600 degrees, thiab argon arc vuam hom diaphragm siab ntsuas tuaj yeem ua haujlwm ib txwm qis dua 1500 degrees.
Tsis tas li ntawd, muaj qee qhov yuav tsum tau ua rau cov ntaub ntawv ntawm qee cov khoom siv hauv cov ntsuas kub-resistant diaphragm siab gauges lossis high-temperature resistant diaphragm pressure gauges. Piv txwv li, lub gasket rau diaphragm siab gauges yuav tsum tsis txhob ua los ntawm yas, tab sis yuav tsum tau siv txhuas los yog lwm yam high-temperature resistant ntaub ntawv; Lub dial ntawm lub diaphragm siab ntsuas yuav tsum tsis txhob siv lub phaj yas, tab sis ib lub phaj txhuas los yog hlau dial. Vim hais tias ntawm qhov kub siab dua, cov yas liner thiab dial yuav deformed thiab cuam tshuam rau kev ua haujlwm ntawm tus taw tes, ua rau lub diaphragm siab ntsuas qhov poob nws txoj haujlwm.
