1. Operating Conditions a zirin Cleaning Frequency tihfel
(1) Fluid hman dan thianghlim
Heat exchanger hian tui thianghlim, tui thianghlim, demineralized water, emaw low-contaminant liquids te a khawih chuan fouling a lo thang zawi zawk a, tihfai hun chhung pawh a sei thei a ni.
Heng dinhmun hnuaiah hian enfiahna leh a tul anga tihfai a tha tlangpuikum 1–2 chhungin vawi khatheat transfer performance nghet tak vawng reng turin.
(2) High-Fouling emaw Contaminated Fluid hmanna
Heat exchanger-te hian suspended solids, sediment, oil emaw minerals sang tak awmna fluid an khawih hian heat transfer surface-ah awlsam takin deposit a awm khawm thei a ni.
Heng hmanna atan hian tihfai hun tawi zawk hman a tha. A tlangpuiin hmanrua chu a ni tur a nithla 3–12 danah enfiah thin a ni a, hnathawh dan tak tak angin tihfai thin a ni.
(3) Chemical leh Corrosive Media hman dan
Chemical processing industry-ah chuan fluid thenkhat chuan corrosion products, crystallization emaw chemical deposit emaw a siam thei a, chu chuan heat transfer efficiency a ti tlem thei a ni.
Process mamawh angin tihfai hun tur siam tur a ni a, a tul hunah online cleaning (CIP) emaw regular disassembly cleaning tih ang chi hmanraw hman tur a ni.
2. Operating Performance a zirin Cleaning mamawh tur ruat
(1) Heat Transfer Efficiency nasa taka tihhniam
Heat exchanger hian outlet temperature mamawh a neih theih tawh loh emaw, heat transfer performance a tlahniam emaw chuan heat transfer surface-ah fouling a awm tawh mai thei.
Fouling hian thermal resistance a tipung a, heat transfer efficiency a ti tlem bawk a, chuvangin enfiah leh tihfai dan tur ruahmanna siam vat tur a ni.
(2) Pressure Drop tihsan chhunzawm zel
Inlet leh outlet inkara pressure danglamna chu normal operating condition nena khaikhin chuan a sang hle a nih chuan flow channel chhunga blockage emaw deposit emaw a awm tih a tilang thei.
Pressure drop sang hian flow capacity a tihtlem bakah pump operating load a tisang a, a hun taka tihfai a ngai a ni.
(3) Flow Rate tlahniam emaw, a nghet lo emaw
Fluid flow tlahniam hian plate channel, tube bundle emaw flow passage-a bawlhhlawh emaw, deposit emaw a awm khawm tih a tilang thei.
Address a nih loh chuan blockage nasa tak a awm thei a, production system pumpui hnathawh dan a nghawng thei bawk.
3. Heat Exchanger chi hrang hrang tana Cleaning Intervals Reference
(1) Plate-a lumna inthlakthlengna
Plate heat exchanger hian heat transfer efficiency sang tak a pe a, mahse an flow channel te tak te hian fouling lakah a sensitive zawk a ni.
Industrial application tlangpui atan chuan enfiah a thathla 6–12 danah a awm thin. Fouling potential sang tak nei fluid tan chuan tihfai fo a ngai mai thei.
Plate heat exchanger te hian mechanical cleaning hi disassembly leh chemical cleaning method hmangin Clean-In-Place (CIP) te hmangin an thlawp tlangpui.
(2) Shell leh Tube-a Heat Exchanger te
Shell leh tube heat exchanger te hian structure nghet tak an nei a, high-temperature leh high-pressure application-ah an hmang nasa hle. Mahse, internal tube fouling hi tihbo a harsa thei hle.
A tlangpuiin enfiah leh tihfai a thakum 1–3 danah, operating medium-a contamination level a zirin a ni.
(3) Spiral Heat Exchanger hmanga thil siam chhuah
Spiral heat exchanger hian an flow design avang hian self-cleaning characteristic chak tak an nei a, mahse high-viscosity fluid emaw, particle awmna fluid emaw an handel hian deposit a la awm thei tho.
Maintenance hi a tlangpuiin pressure drop leh heat transfer performance inthlak danglamna atanga schedule tur a ni.
4. Faina Schedule \\ha tak siam dan
(1) Operating Data Monitoring System siam
Inlet leh outlet temperature, flow rate, pressure tlahniam, leh heat transfer performance te record fo thin ang che.
Operating data-a trend analysis hian fouling chhinchhiahna hmasa berte hriatchhuahna leh tihfai hun tha ber hriat theihna a pui thei a ni.
(2) Fouling Type a zirin Cleaning Method dik tak thlang rawh
Chemical cleaning hmang hian mineral deposit, scale leh chemical dang awmte chu paih chhuah theih a ni.
Mechanical flushing, brushing, emaw disassembly cleaning hi sediment leh solid particle te paih chhuahna atan a tha hle.
(3) Thianghlim lutuk loh tur
Thianghlim fo hian disassembly operation a tipung a, hei hian gasket wear a ti chak thei a, equipment service life pawh a ti tlem thei bawk.
Thianghlimna hi hun bituk chhunga a tul lo taka tih ai chuan hnathawh dan tak takah a innghat tur a ni.
5. Hun rei tak-Hun rei tak chhung enkawl dan tur rawtna
Company-te chuan heat exchanger-te enkawlna record an siam tur a ni a, chutah chuan tihfai hun, hman dan tur, leh hmanrua dinhmun te pawh a tel tur a ni.
Continuous operating system tan chuan preventive maintenance leh condition monitoring te chu inzawmkhawmin performance tihchhiat hmaa tihfai hun tur ruahman tur a ni.
Regular cleaning hian fouling resistance a ti tlem a, heat transfer efficiency a ti tha a, heat exchanger service life a ti rei bawk.
