Spiral heat exchanger: Spiral flow channel structure hmangin fluid turbulence tha tak a pe a, scaling a nei tlem zawk a, self-cleaning capabilities chak tak a nei bawk. Viscosity sang, awlsam taka scaling, leh bawlhhlawh-containing media atan a tha a, chemical bawlhhlawh tihfai, oil processing, leh sewage tihfai nan te hman a ni nasa hle.
4
Air-cooled heat exchanger: Thli chu cooling medium atan hman a nih avangin tui resources a mamawh lo va, hei vang hian tui-a tlakchhamna hmun leh pawn lama hnathawhna hmun atan a tha hle. Oil leh gas industry, power plant, lungalhthei laihchhuahna hmun hla tak tak, leh ram pawn lama project dang tui-harsatna hmunah te hman a ni ber.
2. Ram pawn atanga siam heat exchanger te hi tualchhung atanga siam hmanrua nena khaikhin chuan eng nge an thatna bulpui ber?
- Process stability tihchangtlun:Precision welding leh mature flow channel design hian heat exchange efficiency mumal tak a siam a, chu chuan hun rei tak-a hnathawh chhungin energy hman a ti tlem a, ram chhunga hmanraw pangngai low-end aiin failure rate a hniam hle bawk.
- Material corrosion laka invenna tha zawk:High-end stainless steel, titanium alloys, leh duplex steel hmangin, complex acid leh alkali environment leh corrosive media atan a tha a, service life rei zawk a pe a, ram pawn lama hnathawhna hmun khirh takah pawh a insiamrem thei bawk.
- Dan zawm dan kimchang:A tlangpuiin international industry standard nena inmil a ni a, certification document set kimchang tak a keng tel a, Europe, America, Middle East, Southeast Asia leh ram danga project-te pawm dan tur a tlin a ni.
II. Core Selection Parameters (Procurement atana Core Basis) chungchanga zawhna leh chhanna
1. Imported heat exchanger thlan hunah key operating parameters confirm tur te chu engte nge ni?
Foreign trade purchase order zawng zawngah hian selection, return leh rework inmil lo a awm loh nan core parameter panga chu verified hmasak a ngai a ni. A chipchiar zawng chu hetiang hi a ni:
1
Medium parameters: Fluid lum emaw, lum emaw chi (tui, steam, heat transfer oil, acid/alkali solution, crude oil, etc.), medium concentration, viscosity, corrosiveness, scaling tendency, leh bawlhhlawh emaw particulate matter awmna.
2
- Temperature parameters: Hot leh cold media-a inlet leh outlet temperature, maximum withstand temperature, allowable temperature rise, normal leh extreme operating condition thliar hrang.
3
- Pressure parameters: Rated working pressure, pressure bearing capacity sang ber, pressure tlahniam phalsak; shell-leh-tube structure te hi high-pressure application atan chuan duh zawk tur a ni.
4
Flow parameters: Medium-a flow rate pangngai, maximum/minimum fluctuating flow rate, heat exchange area leh hmanrua dimensions direct-a tichiangtu.
5
Hnathawh dan: Hnathawh chhunzawm zel/a hun lai, load inthlak danglam theihna, installation environment (indoor/outdoor, dry/wet, corrosive atmosphere).
2. Heat exchange power tha lo leh heat exchange effect tha lo awm chhan ber berte chu engte nge ni?
- Selection parameter inthlak danglamna:Heat exchange load hi actual maximum operating conditions atanga chhut a ni lo va, hei hian full-load operation chhunga heat exchange mamawh phuhruk thei lo, undersized equipment a siam a ni.
- Flow channel matching dik lo:Medium flow velocity hi equipment flow channel nen a inmil lo a, hei hian fluid hian effective turbulence a siam thei lo va, heat exchange efficiency pawh nasa takin a tihhniam bawk.
- Scaling leh clogging chungchangah hian:Medium hi scaling a duh hle a, mahse anti-scaling structure erawh thlan a ni lo. Hun rei tak- hnathawh hian plate leh tube bundle-ah scaling a thlen a, hei hian heat transfer a tikhawtlai a ni.
- Installation leh commissioning tihsual a awm: Inlet leh outlet pipe connection inverted emaw, tilted equipment dah emaw hian fluid distribution a inang lo va, heat exchange hmanna a ti tlem bawk.
III. Material thlan dan Q&A (Corrosion laka invenna leh Service Life atana pawimawh) .
