Silicon carbide heat exchanger hi chemical, metallurgical, leh energy industry-ah te hman a ni nasa hle a, a chhan chu a temperature sang-temperature leh corrosion resistance tha tak leh thermal conductivity sang tak a nih vang a ni. Hnathawh tha leh him taka kalpui theih nan hnathawh dan dik a pawimawh hle.
1. Pre-Startup atana inbuatsaihna
Silicon carbide heat exchanger i start hmain hmanrua chu uluk takin enfiah la, heat exchanger ngeiah pawh, piping-ah emaw, fittings-ah emaw leak emaw, chhiatna emaw a awm loh nan. Tin, cooling medium (tui emaw gas emaw ang chi) supply system chu a thawk tha em tih enfiah la, bawlhhlawhin flow channel a tihkhawtlai loh nan medium chu a thianghlim em tih enfiah bawk ang che. A tir lama hnathawh hmain system sealing dik tak a awm theih nan airtightness test neih hmasak a tha.
2. Startup leh Operation
Startup lai hian zawi zawiin low-temperature fluid (cooling water ang chi) dah la, chutah chuan temperature danglamna lian tak avanga thermal stress damage awm loh nan temperature chu zawi zawiin tihsan rawh. Operation chhung hian inlet leh outlet temperature leh pressure te chu design parameter chhunga awm a nih theih nan khauh takin control thin ang che. Temperature leh pressure monitoring devices dah a tha a, chu chuan hnathawh dan chu a hun takah enfiah a, overheating emaw overpressure emaw a awm loh nan a tha hle. Vibration emaw noise pangngai lo hmuhchhuah a nih chuan unit chu khar a, enfiah nghal tur a ni.
3. Enkawl leh Shutdown
Heat exchanger flow path chu tihfai fo la, heat transfer efficiency tichhe thei scale leh deposit awm loh nan. Downtime rei tak chhung hian internal media chu drain la, inert gas (nitrogen ang chi) hmangin boruak lum avanga corrosion awm loh nan. Hun rei tak chhung downtime hnua system hi i chhunzawm leh a nih chuan official-a hman tan hmain thil danglam a awm lo tih finfiah turin trial run nei rawh.
4. Fimkhur dan tur
Operator te hian operating error a awm loh nan equipment parameter te an hriat chian a ngai a ni. Silicon carbide heat exchanger hi temperature sang-resistant ni mahse, an service life rei zawk nan operating condition nasa tak (sudden overheating ang chi) atanga venhim a ngai a ni. Seal te hi enfiah fo tur a ni a, a tul chuan thlak tur a ni a, hei hian hun rei tak-a hnathawh dan nghet tak a neih theih nan.
Standardized operation leh regular maintenance hmang hian silicon carbide heat exchanger te hian heat transfer performance tha leh rintlak tak an vawng reng thei a, industrial production tan pawh support chak tak a pe thei a ni.
