1. Skel i kamap insait long 'heat exchanger' na dispela i mekim na 'heat transfer efficiency' i go daun.
Fouling i save mekim 'thermal resistance' i go antap na i save daunim 'heat transfer capacity'
Long taim bilong wok longpela taim, ol pipia, mineral, oil, o ol samting bilong korosen insait long wara i save go isi isi long hap bilong hat, na kamapim wanpela 'fouling layer'.
Fouling i save mekim 'heat transfer resistance' i go antap, na i save daunim 'efficiency' bilong 'heat exchange' namel long ol hot na kol wara, na dispela i save mekim 'outlet temperature' i no inap long inapim ol 'design requirements'.
2Fouling i save bagarapim ol kondisen bilong ron bilong wara
Wanpela tikpela 'fouling layer' i save daunim 'flow channel area', na daunim 'fluid velocity' na daunim 'turbulence', na dispela i save daunim moa yet 'heat exchange effect'.
Long ol bikpela hevi, 'fouling' inap long pasim 'flow channel', na dispela i save mekim 'pressure drop' i go antap na wok bilong ol ikwipmen i no wok gut.
3-pela rot bilong stretim hevi
Wokim wanpela plen bilong klinim oltaim bihainim ol pasin bilong medium, olsem yusim kemikel klinim, mekenikel klinim, o onlain CIP klinim.
Long ol wok kondisen we i save kamapim pipia, stretim 'fluid flow rate' bilong abrusim 'low-velocity operesen we i save kamapim 'deposition'.
2. Inaf Fluid Flow Rate i mekim Heat Exchange Efficiency i go daun
Low Flo Rate i save mekim hat i senis
Ol 'heat exchanger' i nidim wanpela 'flow rate' bilong kisim gutpela 'heat exchange'. Taim 'flow rate' long sait bilong hat na kol i liklik long 'design value', namba bilong wara we i stap insait long 'heat exchange' long wanwan yunit taim i go daun.
Sapos 'flow rate' i no inap, dispela bai mekim na 'outlet temperature' i no wankain olsem ol 'design parameters', na dispela bai daunim 'heat exchange efficiency'.
2-pela as bilong 'abnormal flow rate'
Dispela i ken kamap bikos 'pump operating capacity' i go daun, 'filta' i pas, 'valve' i no inap long op, o 'pipeline resistance' i go antap.
Long ol 'plate heat exchanger', 'uneven flow distribution' i ken kamap bikos 'plate blockage'.
3-pela rot bilong stretim hevi
Sekim wok bilong pam, op bilong valv, na senis bilong presa bilong paiplain.
Klinim ol 'flow channel' bilong filta na 'heat exchanger' long meksua olsem wara i wok long 'design flow rate'.
3. Nogat Inaf Tempereja Difrens i save mekim wok i go daun
Difrens bilong Tempereja em i as bilong hat senis
Ol 'heat exchanger' i save dipen long 'temperature difference' namel long ol hot na kol wara long kisim 'heat transfer'. Sapos 'temperature difference' namel long 'hot' na 'cold inlet' sait i liklik tumas, 'heat transfer force' i no inap.
Maski sapos ol ikwipmen i wok gut, ol i no inap long kisim 'heat exchange capacity' we ol i makim.
As bilong Nogat Inap Tempereja Difrens
Tempereja bilong hat sos i go daun, eksampel, presa bilong stim i no inap o tempereja bilong hat wara i go daun.
Tempereja bilong kol i save go antap, olsem, wara bilong kol i no inap ron gut.
3-pela rot bilong stretim hevi
Sekim saplai bilong ol 'heat' na 'cold sources' long painimaut sapos 'inlet temperature' i inapim ol 'design conditions'.
Skelim gut 'ratio' bilong 'hot' na 'cold fluid flow rates' long mekim 'average temperature difference' i go antap.
4. Heat Exchanger Flow Channel Blockage o Abnormal Pressure Drop
Blokej i save bagarapim nomol fluid flo
Sapos ol pipia i pasim ol rot insait long 'heat exchanger', wara i no inap ron gut long hap bilong 'heat exchange'.
Distribusen bilong wara i no wankain i save daunim gutpela eria bilong senisim hat, na i pasim sampela eria long insait long hat transfe.
Abnormal Presa Drop em i wanpela bikpela samting bilong soim olsem blokage
Taim 'operating pressure drop' i antap tru long 'design value', dispela i save soim olsem i gat 'internal fouling', 'scaling', o 'flow channel' i pas.
Longpela taim wok wantaim bikpela presa i pundaun inap tu long mekim pamp i yusim planti pawa moa.
3-pela rot bilong stretim hevi
Oltaim sekim 'inlet' na 'outlet' presa na skelim wantaim ol 'design parameters'.
Rausim na klinim o 'backflush' ol ikwipmen we i pas nogut tru.
5. Nogut Pefomens Bikos Nogut Heat Exchanger Disain na Seleksen
Nogat inap hap bilong senisim hat
Sapos namba wan disain eria bilong 'heat exchanger' i no inap, em i no inap long inapim ol samting ol i laikim bihain long ol senis i kamap long wok bilong en.
Ol samting we i save kamap planti taim em olsem, 'production capacity' i go antap, 'flow rates' i go antap, o senis long 'process tempereture'.
Kain Hit Eksenja we i no gutpela
Ol kain kain 'heat exchanger' i gutpela long ol kain kain ples bilong yusim. Olsem, ol 'plate heat exchanger' i gutpela long ol wok we i gat bikpela -efisiensi na liklik wok; ol 'shell-' na '-' 'tube heat exchanger' i gutpela long ol ples we i gat bikpela hat, na i gat bikpela presa.
Sapos kain ikwipmen i no wankain, dispela inap long kamapim liklik 'heat exchange efficiency' o hevi long mentenens.
3-pela rot bilong stretim hevi
Sekim gen ol samting bilong wok, olsem 'flow rate', tempereja, presa, na ol samting bilong 'medium'.
Sapos i gat nid, skruim hap bilong senisim hat o senisim wantaim wanpela kain hat senis we i gutpela moa.
6. Ol hevi bilong pasim 'heat exchanger' we i mekim wok bilong en i no gutpela
Siling Feil i Afektim Heat Exchange Process
Long ol 'plate heat exchanger', ol 'gasket' i go lapun, i bagarap, o ol i no putim gut na dispela inap long kamapim ol 'internal leaks'.
Taim yu miksim tupela wara dispela i save daunim 'heat exchange efficiency' na dispela inap long bagarapim kwaliti bilong prodak na sefti bilong sistem.
Ol samting i soim ol hevi bilong pasim
Ekstenel lik i kamap.
Ol 'inlet' na 'outlet' tempereja we i no stret na ol senis long presa we i no stap gut.
3-pela rot bilong stretim hevi
Oltaim sekim kondisen bilong ol gasket na senisim olpela o bagarap sil.
Putim ol plet long 'torque' we yu makim, na noken taitim tumas.
Sapos yu laik save moa long ol 'heat exchanger units' o yu laik baim, plis salim wanpela email i go long 9988xiaoshuai@gmail.com, mipela bai bekim yu hariap bihain long mipela i lukim dispela toksave!
