FAQ
Q: Kuv yuav xaiv qhov watt ntom ntom kom yog li cas thiaj li tiv thaiv kev ntsuas ntxov ntxov?
A: Keep surface watt loading below 12 W/cm² for standard tap water containing minerals. Exceeding this threshold accelerates calcium carbonate precipitation on the sheath surface, insulating the element and causing thermal overload failure. Use higher watt densities (>= 15 W/cm²) tshwj xeeb rau kev ua kom huv, deionized, lossis cov txheej txheem dej.
Q: Qhov txawv ntawm Incoloy 800 thiab SS316L sheath cov ntaub ntawv yog dab tsi?
A: SS316L muab kev tiv thaiv corrosion txaus rau cov dej huv thiab cov dej me me txog li 60 degree. Incoloy 800 nta nickel ntau dua -chromium cov ntsiab lus, muab kev tiv thaiv zoo tshaj plaws rau chloride kev nyuaj siab corrosion cracking, oxidation, thiab scaling ntawm kev khiav hauj lwm kub txog li 800 degree.
Q: Cov khoom puas tuaj yeem hloov tus kheej yog tias ib qho ua tsis tiav hauv cov flange pob?
A: Tus qauv hairpin nras tsim cov ntsiab lus welded ncaj qha rau hauv lub phaj flange, yuav tsum tau hloov tag nrho cov pob. Txawm li cas los xij, bolted-hauv cov txheej txheem tshem tawm tau siv cov compression fittings tuaj yeem tsim kho rau siab - muaj peev xwm ua haujlwm uas yuav tsum muaj kev pabcuam tus kheej.
Q: Cov ntawv pov thawj dab tsi siv rau qhov chaw muaj kev phom sij ntawm qhov chaw nres tsheb?
A: Standard units nkoj nrog NEMA 4/4X weatherproof enclosures. Rau cov chaw muaj kev phom sij uas muaj cov pa taws los yog vapors, cov ntaub ntawv pov thawj rau ATEX Zone 1/2 lossis UL / CSA Class I, Division 1 thiab 2 cov qauv raug teev tseg thaum lub sijhawm tshuaj xyuas engineering.
Q: Yuav ua li cas thermal cutouts muab tso rau hauv flange sib dhos?
A: Ib qho thermowell sab hauv tsev muaj lub ntsuas kub capillary, bimetallic disk hloov, lossis RTD sensor xaim mus rau tus tiv thaiv kev nyab xeeb sab nraud. Qhov no yuav txiav fais fab tam sim ntawd yog tias cov kua dej poob qis hauv qab ntawm thaj chaw ua cua sov, tiv thaiv kom qhuav - hluav taws xob sheath melting.
