Diaphragm siab gauges yeej muaj qee yam 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 neeg ua ntej nkag siab txog qhov ntsuas kub ntawm lub diaphragm siab npaum li cas tuaj yeem tiv taus. Yog li dab tsi yog qhov kub ntawm qhov ntsuas kub ntawm lub diaphragm siab ntsuas?
Nyob rau hauv cov qauv ntawm ntau yam diaphragm siab ntsuas nyob rau hauv kuv lub teb chaws, feem ntau tsuas yog ib tug ib txwm ua hauj lwm qhov chaw kub ntawm lub diaphragm siab gauge yog teev. Piv txwv li, lub diaphragm siab gauge yog -40-70 degrees, thiab lub diaphragm siab ntsuas yog -25-55 degrees. kub tiv thaiv 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-resistant diaphragm siab gauges, ob peb lub diaphragm siab gauge manufacturers qhia kom meej txog qhov kub-resistant kub los yog high-temperature kuj kub ntawm diaphragm siab gauges. Qhov no kuj ua rau nws nyuaj rau cov neeg siv cov diaphragm siab ntsuas.
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 ntoos hlav, uas yog:
Brazing (tin soldering), qhov kub thiab txias thaum lub sij hawm vuam yog 120 degrees, thiab nws yog feem ntau yog siv rau welding ntawm tooj liab pob qij txha thiab tooj liab caij nplooj ntoos hlav raj.
Nyiaj vuam, qhov kub thaum lub sij hawm vuam yog 600 degrees, thiab nws yog feem ntau yog siv rau vuam tooj liab pob qij txha thiab stainless hlau caij nplooj ntoos hlav raj.
Argon arc vuam, qhov kub ntawm vuam yog 1500 degrees, thiab nws 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 ntawm qhov ntsuas kub uas lub diaphragm siab ntsuas tuaj yeem tiv taus, uas yog, qhov ntsuas qhov ntsuas siab ntawm lub diaphragm tuaj yeem ua haujlwm ib txwm qis dua 120. degrees, thiab cov nyiaj welding Diaphragm siab ntsuas tuaj yeem ua haujlwm ib txwm qis dua 600 degrees, thiab argon arc welded diaphragm siab ntsuas tuaj yeem ua haujlwm ib txwm qis dua 1500 degrees.
Tsis tas li ntawd, kuj tseem muaj qee qhov yuav tsum tau ua rau cov khoom siv ntawm qee cov khoom siv hauv cov cua kub-resistant diaphragm siab gauges lossis high-temperature diaphragm siab gauges. Piv txwv li, cov gaskets siv nyob rau hauv diaphragm siab gauges yuav tsum tsis txhob ua los ntawm yas, tab sis txhuas los yog lwm yam high-temperature resistant ntaub ntawv. Lub dial ntawm lub diaphragm siab ntsuas yuav tsum tsis txhob siv ib tug yas disc, tab sis ib tug txhuas los yog hlau dial. Vim hais tias ntawm qhov kub siab dua, lub nplhaib yas thiab dial yuav deform thiab cuam tshuam rau kev ua haujlwm ntawm tus taw tes, ua rau lub diaphragm siab gauge poob nws txoj haujlwm.
