Cooling Tower khar tawhte tana Routine Maintenance leh Anti-Freezing Protection chungchanga kaihhruaina kimchang tak

Industrial production-a heat exchange hmanrua pawimawh tak a nih angin, cooling tower-te stable operation hian direct-in production chhunzawm zel a tichiang a ni. Heat exchange structure hmanga siam a ni a, .Oasis Bingfeng chuan cooling tower te chu a khar ahun rei tak-efficiency sang tak-efficiency heat transfer vawng nung turin nitin standardized leh systematic maintenance a mamawh. Equipment-a technical specification original aṭanga chhut chuan, he document hian maintenance solutions a buatsaih a, core section pathum: spray system operation & maintenance, winter anti-freezing measures leh makeup water supply, production leh maintenance personnel-te en theih turin a huam a ni.

 

I. Spray System atana Routine Maintenance Point pawimawh tak tak

 

Spray system hian pawn lam core heat exchange component ofcooling tower khar a ni.Nitin enfiah leh enkawlnaah a hnuaia specification te hi hman tur a ni:

 

1. Tui Quality Control: 1.1.

Tui nêm (softened water) hi a hnuai lama tui dahna atan chuan a tha zawkcooling tower khar a ni.Heat exchange tube-a scaling leh corrosion hlauhawmna tihziaawmna turin tui pH value chu 6 leh 8 inkar a ni tur a ni.

 

2. A hun hunah tihfai thin:

Air intake grilles leh filter screen-a deposit awmte chu kar tin tifai la, boruak kal dan mumal tak a awm theih nan. Leivut leh hnathawhna hmun harsa takah pawh cleaning cycle hi tih tawi theih a ni a, hei hian air volume tihtlem leh cooling performance tihchhiat a veng thei a ni.

 

3. Pipeline enfiahna: 1.1.

Spray tui sem dan hi enfiah fo ang che. Tui luang dan inang lo emaw, tui cut-off emaw a nih chuan pipeline leh spray nozzle-a blockage awmte chu chinfel nghal vat tur a ni.

 

4. Fan dinhmun enfiah dan:

Fan blade te hi uluk takin ngaihven rawh. Dust nasa tak a awm chuan dynamic imbalance a siam ang a, chu chuan fan ri leh vibration pangngai lo a siam ang. Case na tak a awm chuan beisei loh takin shutdown a awm thei a, production pawh a tibuai thei bawk.

II. Thlasik atana Anti-Freezing Measures pawimawh tak tak (Top Priority)

 

A heat exchanger a nicooling tower khar a nicold resistance tlemte nei, thin-walled copper tube a hmang thin. Tui la awm chu temperature hniam hnuaia freezing hian awlsam takin copper tube a ti chhe thei a ni. Freezing avanga chhiatna thleng chu warranty hnuaiah a awm lo. Thlasik hnathawh chhung hian anti-freezing scheme khauh taka kalpui a ngai a ni:

 

1. Ambient temperature 0℃aia hniam a nih chuan copper tube chhunga tui awm chhunte chu a khar hnuah a freeze thei a, chu chuan tube a chhe thei a ni.

 

2. Continuous Winter Operation: Hun rei lote-shutdown-a freeze loh nan circulating medium-ah qualified antifreeze dah tel a ngai.

 

3. Hun rei tak-chhunga hmanraw tihtawp: Heat exchanger, circulating pipeline, valve leh pump atanga tui zawng zawng paih vek tur; spray water tank leh tui dahna tank kha empty la, blowdown valve hawng la, full drainage a awm theih nan, heat exchanger leh pipeline chhunga tui awm chhunte chu compressed air hmangin tifai rawh.

 

4. Idle Equipment Protection: Exhaust outlet leh tower body atan pawn lam khuhna dah tur a ni. System water tank layout chu shutdown status hnuaia heat exchanger aiin liquid level a hniam theih nan optimize rawh.

 

5. Spray system a service loh laiin spray tank atanga tui a hun taka chhuah tir la, a vawt loh nan.

 

⚠️ Vaukhânna pawimawh: Pipe freezing accident a awm loh nan thlasik chhunga hman theih turin circulating system-ah antifreeze dah tel a ngai!

 

III. Spray System-a Makeup Tui atana chhut dan

 

Hmanraw hman chhungin spray tui hi hman chhunzawm zel a ni ang. Makeup tui volume zawng zawng hi hloh chi thum zawng zawng zatvea chhut a ni:

Makeup Tui Volume=Evaporation hloh + Drift hloh + Blowdown Volume

 

1. Evaporation hloh: 1.1.

Operational consumption pangngai tak a ni. Spray tui a vawt chuan vaporization to latent heat a paih chhuak aheat exchange leh cooling tih hriat chian, leh operating load nen tui hman a pung bawk.

 

2. Drift hloh: 1.1.

Tui tla te te chu boruak lum lum chhuak chhuakin a luhchilh thin. He hmanrua hian drift loss tihtlem nan honeycomb inward-inclined air intake grilles a hmang a, hei hi theoretically chuan spray flow rate atanga 0.05% anga chhut theih a ni.

 

3. Blowdown atanga hloh: 1.1.

Continuous evaporation hian tuiah calcium leh magnesium ion a concentrate a, hei hian awlsam takin heat exchange tube pawn lam ah scale a siam a, heat transfer performance a tichhe bawk. Ion concentration tihhniam nan blowdown neih fo a ngai a, blowdown volume hi spray flow rate atanga 0.3% vel anga chhut theih a ni.

 

IV. Maintenance chungchang thupui

 

Hlawhchham tam zawk chucooling tower khar a ninitin enfiahna tling lo, thlasik anti-freezing measures mumal lo leh tui quality enkawl ngaihthah avanga lo chhuak a ni. Spray system tihfai fo, thlasik anti-freezing procedure khauh taka kalpui, makeup tui chhiar dan dik tak leh periodic blowdown cancooling performance a ti nghet thei, heat exchanger, fan leh pipeline te service life pawh ti sei. Hetihlai hian heng hmalaknate hian tube cracking leh scaling ang chi chhiatna lian tham a awm loh nan a pui a, factory khar avanga maintenance cost pawh a tihtlem phah bawk.
