A hman hun chhung hian plate-type heat exchanger unit hian hmanrua a tichhia ang a, heat exchange efficiency a nghawng ang a, thil hrang hrang avanga hman tangkai leh service life a nghawng bawk ang. Chuti a nih chuan, plate-type heat exchanger unit-a heat exchange efficiency tlahniam chhan chu eng nge ni?
Material leh structural factors te .
Material duhthlanna dik lo: Plate heat exchanger atana material thlan dan dik lo a nih chuan, heat transfer coefficient tlem zawk hmanga material hman ang chi a nih chuan heat exchanger-a heat transfer performance pumpui a nghawng dawn a ni. Material thermal resistance a lian a, chu chuan heat transfer efficiency a tihhniam a, chu chuan heat transfer efficiency a nghawng a ni.
A structure hi a dik lo: Plate structure-ah design defect a awm a nih chuan, a lum leh a lumna hmunte chuan heat exchange area chu a tawk kim thei lo ang, local temperature danglamna lian tak a thlen ang a, heat exchange area pawh a hmang kim thei lo ang. Heat transfer hi a inang lo a, hei vang hian heat exchange efficiency zawng zawng a tlahniam a ni.
fluid factors 1.1.
Low flow rate emaw blockage emaw: Fluid sir khata flow rate hniam chuan wall-a fluid boundary layer chu a ti thim lutuk ang a, heat transfer a nghawng ang. Chutih rual chuan fluid chhunga particle te chuan plate channel chu an block thei a, chu chuan fluid flow rate a ti tlem thei bawk. Heat transfer rate a tlahniam a, heat transfer efficiency pawh a tlahniam bawk.
Scaling: Fluid chhunga bawlhhlawh awmte chu plate chung lamah a lo awm thei a, chu chuan scale layer a siam thei a ni. Scale layer hian thermal conductivity tha lo tak a nei a, hei hian heat transfer a tikhawlo a, hei hian heat exchange efficiency a tihhniam phah a ni.
Sealing leh leakage .
Gasket aging emaw damage emaw: Hun rei tak chhung-Term-a hnathawh hnuah chuan plate heat exchanger-a gasket chu tar, chhiatna, emaw, detachment vangin a hlawhchham thei a ni. Fluid leakage a awm a, chu chuan heat transfer efficiency a tihhniam a, chutih rual chuan medium mixing hian system kalphung pangngai a nghawng thei bawk.
Blade deformation emaw misalignment emaw: Blade te chu accidental impact emaw, dik lo taka hman emaw a nih avangin a deform emaw misalign emaw thei. Hei hian seal a tichhia a, fluid leakage a thlen a, heat exchange efficiency a nghawng bawk.
Operating Conditions inthlak danglamna .
Temperature danglamna a tlahniam: Heat source leh cold source inkar temperature danglamna a tlahniam a, heat transfer atana driving force pawh a tlahniam bawk.
Flow Rate Change: Fluid flow rate inthlak danglamna, flow rate tihhniam ang chi hian unit time khata heat exchanger plate kaltlanga heat transfer a tlahniam ang.
Enkawlna dik lo .
Hun chhunga tihfai loh: Hun rei tak chhung-Term operation hnuah chuan plate surface-type heat exchanger chu impurities te chu scale emaw adhere emaw a ni thei. A hun taka tihfai loh chuan scale layer leh bawlhhlawh hian heat transfer a tikhawlo ang a, chu chuan heat exchange efficiency a ti tlahniam ang.
Maintenance not up to standard: chutiang chu gasket chu a hun taka thlak loh, plate siam that loh ang chi te, etc. Equipment performance chu a tlahniam zauh zauh a, heat exchange efficiency pawh a tlahniam bawk.
A tawp berah chuan, plate-type heat exchanger unit-a heat transfer efficiency tlahniam chhan chu material leh structure, fluid, seal leh leakage, operating conditions, maintenance leh aspect dang tam tak a ni thei. Heat transfer efficiency tihchangtlun nan design, selection, operation, maintenance leh link dangte atanga tan a ngai a, comprehensive measures kalpui a ngai bawk. Entirnan, material leh structure dik tak thlang la, fluid flow rate leh flow tha zawk siam la, seal leh leakage management tichak la, hmanrua tihfai leh enkawl reng la, etc.
