Ho betla tšepe ea Tubesheet bakeng sa Heat Exchanger
Lipalong tsa moralo bakeng sa li-exchange tsa mocheso oa lakane ea tube tse tsitsitseng, haeba ho na le boemo boo khatello ea axial ea khetla, khatello ea axial ea phapanyetsano ea mocheso, kapa matla a ho hula pakeng tsa phapanyetsano ea mocheso le lakane ea tube li ke keng tsa fihlela litlhoko tsa matla (kapa botsitso), hoa hlokahala ho kenya lenonyeletso la katoloso. Maemong a mang, kamora ho fumana botenya ba lakane ea tube, matla a lakane ea tube a kanna a se lekane ntle le lenonyeletso la katoloso. Leha ho le joalo, ka ho eketsa lenonyeletso la katoloso, botenya ba lakane ea tube bo ka fihlela litlhoko. Maemong a joalo, qeto ea ho kenya lenonyeletso la katoloso e lokela ho ipapisa le tlhahlobo e felletseng ea tšebeliso ea thepa, bothata ba tlhahiso, polokeho le litlamorao tsa moruo.
Mofuta o atisang ho sebelisoa oa lenonyeletso la katoloso ho li-transaction tsa mocheso tsa lakane ea tube e tsitsitseng ke lenonyeletso la katoloso le bōpehileng joaloka U, le lenyenyane, le bonolo ka sebopeho, le na le litšobotsi tse ntle tsa puseletso, 'me le theko e tlaase. Ka boholo bo ntseng bo eketseha ba lisebelisoa tsa lik'hemik'hale le lifeme tsa motlakase, bophara ba lakane ea tube bo se bo le boholo, 'me bophara ba 4m ho isa ho 5m bo tloaelehile. Lakane e meholo ea tube e khetholloa ka palo e kholo ea masoba a manyane a teteaneng a nang le litlhoko tse phahameng tsa ho nepahala le bohloeki.
Li-tube sheet li sebelisoa haholo liindastering tse kang li-heat exchanger tsa khetla le tube, li-boiler, li-pressure vessels, li-turbines, le litsamaiso tse kholo tsa central air conditioning. Li sebelisoa haholo-holo ho tšehetsa le ho lokisa li-tube tse ka har'a lik'hemik'hale, tse kang li-heat exchanger tsa khetla le tube, li-pressure vessels, li-condensers, litsamaiso tsa central air conditioner, li-evaporator le limela tsa ho tlosa letsoai metsing a leoatle. Thepa ea tšepe ea li-tube sheet ha e fane feela ka ho tiea ho hoholo empa hape e fana ka litšobotsi tse ntle tsa ho tsamaisa mocheso.
Nakong ea tlhahiso ea li-exchange tsa mocheso oa khetla le tube, ho tjheseletsa lakane ea tube le li-tube hangata ho etsoa ka ho tjheseletsa tšepe ea arc e sirelelitsoeng ka letsoho, e leng se lebisang boteng ba liphoso sebopehong sa weld, joalo ka likoti, li-pores le lintho tse kenyellelitsoeng, hammoho le kabo e sa lekanang ea khatello ea weld. Ha e sebelisoa, likarolo tsa lakane ea tube hangata li kopana le metsi a pholileng a indasteri, e leng se ka bakang ho bola ha lakane ea tube le li-weld ka lebaka la litšila, letsoai, likhase le likokoana-hloko tse teng metsing a pholileng a indasteri - sena se tsejoa e le electrochemical corrosion.
Diphuputso di bontsha hore metsi a diindasteri, ebang ke a foreshe kapa a lewatle, a na le di-ion tse fapaneng le oksijene e qhibilihileng, ka dipharologanyo tsa mahloriso tsa di-ion tsa chlorine le oksijene di bapala karolo ya bohlokwa sebopehong sa tshepe. Ho feta moo, ho rarahana ha sebopeho sa tshepe le hona ho ka ama sebopeho sa tshepe. Ka hona, mefuta ya mantlha ya tshepe ya lakane ya tube le di-weld tsa tube ke tshepe e nang le dikoti le tshepe e phunyang.
