Cooler enkawlna hi hmanrua hman dan pangngaia hman theihna tur leh a service life tihzauh nan a pawimawh ber a ni. A hnuaia tarlan te hi maintenance precaution pawimawh tak tak thenkhat an ni:
1. Nitin enfiah .
Hmuh enfiahna: Nitin hnathawh hmain emaw, shift tin emaw hnathawh hmain cooler hmel chu enfiah la, chutah chuan shell-ah leakage a awm leh awm loh te, a bik takin tube sheet connection, inlet leh outlet flanges, weld leh part dang te pawh a tel.
Temperature Monitoring: Inlet leh outlet pipe temperature tehna atan infrared thermometer ang chi hmanrua hmang la, a temperature chu a pangngaiin a awm theih nan.
Pressure Observation: Cooler inlet leh outlet-a pressure indicator instrument chu enfiah la, pressure value chu record la, pressure chu a nghet em tih enfiah rawh.
2. Enkawl dan pangngai .
Thianghlimna hna: Cooler shell chu uluk takin tifai la, leivut, oil leh bawlhhlawh dangte chu a chung lamah paih la, heat dissipation a nghawng loh nan leh shell tichhe lo turin.
Cooling Medium Inspection leh Replacement: Cooler hian tui leh cooling media dang awlsam taka tihbawlhhlawh emaw, scale emaw a hman chuan a tui quality test reng a ngai a, pH value, hardness, suspended matter content leh indicator dangte pawh enfiah a ngai a, test result atanga tui tihfai emaw, cooling media thlak emaw a ngai em tih rel a ngai bawk.
Bolt tightening: Cooler connection point tina bolt te chu enfiah la, tube sheet leh shell inkar connection bolt te, inlet leh outlet flanges te connection bolt te, etc. te pawh a tel a, torque wrench tha tak hmang la, torque mamawh tur tarlan angin tight la, chu chuan equipment operation laiin bolt te chu a vibration loh nan a lo awm loh nan, leakage leh harsatna dang a thlen thin.
3. Kum tin enkawl dan .
Internal inspection leh cleaning: Shutdown hnuah cooler tawp cover kha hawng la, tube bundle chu la chhuak la, tube bundle chhung leh pawn lam leh a chhung lam bang chu chipchiar takin enfiah rawh. Tube bundle-ah hian corrosion, wear, deformation, etc. a awm leh awm loh enfiah la, tube bundle-ah harsatna neiin, a chhiatna℃a zirin siam that emaw, thlak emaw tur nge tih i rel thei ang.
Instrument calibration: Temperature instrument, pressure instrument, etc. calibrate la, an measured value te dik leh dik loh enfiah turin cooler-ah dah rawh.
Anti-corrosion treatment: Anti-corrosion treatment hi a pawn lam shell leh cooler chhunga visible metal surface-ah an ti a. Pawn lam shell-a rusted part-te tan chuan rust removal hi tih hmasak tur a ni (grinding, sandblasting, etc. hman theih a ni), chutah chuan anti-corrosion paint dik tak hman tur a ni Internal metal surface tan chuan anti-corrosion coating chu a dinhmun tak tak angin a hman theih a, chu chuan hmanrua te corrosion resistance a tichak a, a service life a ti rei thei bawk.
4. Spare parts enkawl dan .
Spare parts inventory management system kimchang tak siamin spare part hman tlanglawn tak tak, sealing gaskets, tube bundles, bolts, etc. te chu reserve la, spare parts te chu a tling tawk a, quality tha tak a nih theih nan spare parts zat chhiar thin ang che. Thil hmanrua a chhiat a, thlak a ngaih hunah chuan hmanrua downtime tihtlem nan spare parts te chu a hun takah pek theih a ni.
