Kev ceev faj rau kev siv Finned Condensers
Tus yuam sij rau kev siv finned condensers yog nyob rau hauv cov qauv kev ua haujlwm, kev saib xyuas tsis tu ncua, thiab kev hloov pauv ib puag ncig kom ntseeg tau tias muaj kev sib pauv cua sov thiab kev ua haujlwm zoo.
Txhawm rau zam kev ua haujlwm tsis zoo lossis cov khoom puas tsuaj, cov ntsiab lus tseem ceeb hauv qab no yuav tsum tau hais txog thaum siv finned condensers:
Tswj cov kev khiav hauj lwm tsis thiab nruj me ntsis txwv tsis pub tshaj kub thiab siab txwv. Finned condensers tau piav qhia meej txog cov kev txwv siab rau lawv qhov kev ua haujlwm kub thiab siab. Piv txwv li, txhuas finned tubes feem ntau haum rau kub hauv qab 300 degree, thaum stainless hlau tuaj yeem tiv taus qhov kub ntawm 800-900 degree. Yog hais tias qhov kub ntawm cov kua dej kub los yog lub zog siab tshaj qhov tsim qhov tseem ceeb, nws yuav ua rau lub raj deformation, weld cracking, los yog lub raj rupture. Nws yog ib qho tseem ceeb los xyuas kom meej tias qhov nruab nrab tsis nyob hauv qhov ntau tau teev tseg ntawm cov khoom siv lub npe lossis cov ntaub ntawv kev tshaj lij.
Tiv thaiv corrosive media yaig thiab xaiv corrosion-cov ntaub ntawv tiv taus. Thaum cov kua dej muaj cov kua qaub, alkalis, lossis cov tshuaj chloride ion siab, nws yooj yim ua rau corrosion tsis ua haujlwm ntawm cov hlab finned. Cov lus pom zoo:
Thaum nyob rau hauv kev sib cuag nrog corrosive media, siv corrosion -cov ntaub ntawv resistant xws li stainless hlau los yog titanium alloy; Galvanize, tin-plat, lossis siv cov tshuaj tiv thaiv -corrosion txheej rau carbon steel fins kom ntev lawv lub neej kev pab cuam; Tsis txhob siv cov tshuaj ntxuav lossis dej txias nrog cov ntsiab lus chloride ion tshaj 25 ppm.
Kev tshuaj xyuas tsis tu ncua thiab kev saib xyuas kom sai txheeb xyuas cov teeb meem tshwm sim:
Kev tshuaj xyuas txhua hli ntawm fins rau deformation, scale buildup, los yog corrosion;
Kev ntsuas lub hlis twg ntawm cov kiv cua ua haujlwm tam sim no, kev hloov pauv huab cua, thiab kev sib pauv cua sov;
Kev ntsuam xyuas siab txhua xyoo thiab kev sib khi kev kuaj xyuas kom ntseeg tau tias muaj kev ncaj ncees.
