FAQ
Q: Dab tsi ua rau roj coking ntawm lub rhaub dej kub, thiab nws tiv thaiv li cas?
A: Oil coking occurs when surface watt density is too high, causing local fluid temperatures to exceed the oil's thermal cracking threshold. Tiv thaiv qhov no los ntawm kev xaiv qhov tsawg watt ntom (3 mus rau 8 W / cm2) sib phim rau qhov tshwj xeeb viscosity ntawm koj cov roj.
Q: Cov cua sov no puas muaj kev nyab xeeb los khiav yam tsis muaj qhov hloov ua kua?
A: Tsis yog. Kev ua haujlwm ntawm lub rhaub dej kub nrog cov ntsiab lus nthuav tawm saum cov kab kua dej (qhuav-firing) ua rau cov sheath overheating sai thiab muaj kev puas tsuaj loj. Cov kua theem interlocks yog yuav tsum tau.
Q: Thaum twg kuv yuav tsum tau qhia meej txog qhov tawg NEMA 7 -cov ntaub ntawv pov thawj?
A: Qhia meej NEMA 7 thaum lub tshuab cua sov ua haujlwm nyob rau hauv qhov chaw muaj kev puas tsuaj uas tau muab faib ua raws li NEC Chav Kawm I, Division 1 lossis 2 ib puag ncig, qhov chaw uas muaj cov pa hluav taws xob lossis roj vapors.
Q: Puas tuaj yeem ntsia hlau ntsia hlau ntsia hlau ntsia hlau los ntawm lub tank saum?
A: Yog lawm, siv lub tank tsim nyog- sab saum toj txuas, muab thaj chaw cua sov ua haujlwm tseem nyob rau hauv tag nrho hauv qab cov dej tsawg kawg nkaus.
Q: Koj ua li cas tiv thaiv hluav taws xob tiv thaiv thaum tsim khoom?
A: Element wattage outputs yog calibrated nyob rau hauv +5% mus rau -10% ntawm nominal tsim specifications ntawm kev khiav hauj lwm kub, ua tau raws li industrial manufacturing qauv.
Q: Cov ntaub ntawv dab tsi yog muab nrog cov khoom xa tuaj?
A: Txhua qhov kev txiav txim suav nrog cov ntaub ntawv ntsuas hluav taws xob, daim ntawv pov thawj khoom siv (MTRs) rau cov khoom ntub dej, thiab cov ntaub ntawv teeb tsa / xaim xaim raws li kev thov.
