Kev tsim cov tank transformer yog cov txheej txheem tshwj xeeb uas yuav tsum tau ua kom lawv cov sealing, lub zog, thiab kev ua haujlwm kub. Qhov no feem ntau ua tiav los ntawm cov kauj ruam tseem ceeb xws li xaiv cov khoom siv, txiav, sib dhos thiab vuam, tiv thaiv- kho corrosion, thiab kev sim nruj.
1. Kev xaiv cov khoom siv
Lub tank feem ntau yog ua los ntawm qis- cov pa roj carbon steel phaj lossis siab - lub zog steel daim hlau kom ntseeg tau tias muaj zog thiab thauj khoom - cov kabmob muaj peev xwm. Rau cov ntawv thov tshwj xeeb los tiv thaiv- cov kev xav tau corrosion, stainless hlau daim hlau kuj tseem siv tau. Cov ntaub ntawv yuav tsum muaj cov thermal conductivity zoo, corrosion kuj, thiab weldability, thiab tau txais kev soj ntsuam zoo ua ntej siv.
2. Txiav thiab sib sau
Raws li kev tsim cov duab kos, cov phaj hlau raug txiav rau hauv cov duab thiab qhov ntau thiab tsawg uas siv lub tshuab txiav los yog txiav tshuab. Rau corrugated los yog folded - phaj (corrugated) tanks, ib txoj kab tshwj xeeb yog siv los nias tawm corrugations los yog quav tawm grooves kom lub tshav kub dissipation cheeb tsam thiab them rau lub thermal expansion thiab contraction ntawm cov roj.
3. Kev sib dhos thiab vuam
Tom qab sib sau ua ke cov ntawv txiav steel, lawv raug kho siv cov txheej txheem vuam. Cov txheej txheem welding feem ntau muaj xws li:
Gas shielded vuam: dav siv nyob rau hauv kev tsim cov corrugated roj tso tsheb hlau luam, txhim kho weld zoo;
Kev tuav arc vuam: Haum rau qhov tsis xwm yeem;
Submerged arc vuam: Haum rau ntev, ncaj welds, muab kev ua haujlwm siab thiab ruaj khov zoo.
Thaum vuam, tam sim no, voltage, thiab ceev yuav tsum tau tswj, thiab cov ntaub ntawv tshwj xeeb yuav tsum tau preheated thiab tom qab-kub kho kom txo tau kev ntxhov siab deformation. Hla pob qij txha yuav tsum tau zam, thiab tus naj npawb ntawm cov welds yuav tsum raug txo kom tsawg los txo qhov kev pheej hmoo ntawm kev xau.
