Mabaka a ho hloleha ha khatello e phahameng ea screw chiller ke a latelang

Khatello ea ho tsoa ha screw chiller compressor e phahame haholo, e etsang hore relay ea tšireletso ea khatello e phahameng e sebetse. The khatello ea khatello ea mali e bonahatsa khatello e fokolang, boleng bo tloaelehileng e lokela ho ba 1.4 ~ 1.6MPa, ‘me boleng ba tšireletso bo behiloe ho 2.0MPa. Haeba khatello e phahame haholo ka nako e telele, e tla etsa hore mochine o sebetsang oa compressor o be moholo haholo, motlakase o bonolo ho chesa, ‘me ho bonolo ho baka tšenyo ea valve ea ho qeta compressor. Mabaka a ho hloleha ha matla a phahameng ke a latelang:

(1) Thempereichara ea metsi a pholileng e phahame haholo ‘me phello ea condensation e fokola. Boemo bo lekantsoeng ba ho sebetsa ba metsi a pholileng bo hlokoang ke screw chiller ke 30 ~ 35 ℃. Mocheso o phahameng oa metsi le mocheso o fokolang oa mocheso o tla lebisa khatellong e phahameng ea condensing. Ketsahalo ena hangata e etsahala linakong tsa mocheso o phahameng. Lebaka la mocheso o phahameng oa metsi e ka ‘na ea e-ba: ho hlōleha ha tora e pholileng, joalo ka ha fene e sa buletsoe kapa e sa fetohe, mofani oa metsi ha a fetohe, o bonahatsoa ha mocheso oa metsi a pholileng o phahame haholo,’ me o phahama ka potlako; mocheso o ka ntle o phahame, tsela ea metsi e khutšoanyane, ‘me palo ea metsi e ka tsamaisoang Tabeng ena, mocheso oa metsi a pholileng o atisa ho bolokoa ka mokhoa o batlang o le holimo, o ka rarolloang ka ho eketsa tanka ea polokelo.

(2) Phallo ea metsi a pholileng ha ea lekana ‘me ha e khone ho fihla ho phallo ea metsi e lekantsoeng. Tshebetso e ka sehloohong ke hore phapang ea khatello pakeng tsa metsi a kenang le a tsoang ho yuniti e fetoha e nyenyane (ha e bapisoa le phapang ea khatello qalong ea tsamaiso e kenngoa ts’ebetsong), ‘me phapang ea mocheso e ba kholoanyane. Lebaka la ho phalla ha metsi a sa lekaneng ke ho hloka metsi tsamaisong kapa boteng ba moea. Tharollo ke ho kenya valve ea ho ntša metsi sebakeng se phahameng sa pipeline ho ntša metsi; sefepi sa liphaephe se koetsoe kapa khetho e ntle haholo, ‘me ho kenella ha metsi ho fokotsehile. U lokela ho khetha sefe se loketseng ‘me u Hloekise sefe ka linako tsohle; pompo ea metsi e nyenyane ‘me ha e lumellane le tsamaiso.

(3) Condenser e silafalitsoe kapa e thibetsoe. Metsi a condensate hangata ke metsi a pompo. Ho bonolo ho lekanya ha mocheso o le ka holimo ho 30 ℃. Hobane tora e pholileng e bulehile, e pepesehile ka ho toba moeeng. Lerōle le lintho tse tsoang linaheng tse ling li ka kena habonolo tsamaisong ea metsi a pholileng, e leng se etsang hore condenser e be litšila le ho thibela le sebaka sa phapanyetsano ea mocheso se senyenyane. , Ho sebetsa hantle ho tlaase, hape ho ama ho phalla ha metsi. Ts’ebetso ke hore phapang ea khatello le phapang ea mocheso pakeng tsa metsi a kenang le a ho tsoa a yuniti e ba kholoanyane, mocheso o ka holimo le o tlase oa condenser o phahame haholo ha condenser e angoa ka letsoho, ‘me phala ea koporo ea condenser e chesa. The screw chiller e lokela ho hlatsuoa ka morao khafetsa, ‘me ho hloekisoa ha lik’hemik’hale le ho theola ho lokela ho etsoa ha ho hlokahala.

(4) The refrigerant is overcharged. This situation generally occurs after maintenance, and it is manifested as high suction and exhaust pressure and balance pressure, and high compressor operating current. It should be vented according to the suction and discharge pressure, balance pressure and operating current under rated conditions until normal.

(5) Likhase tse sa koaheleng tse kang moea le naetrojene li tsoakoa ka sehatsetsing. Boemo bona hangata bo etsahala ka mor’a tlhokomelo, ‘me vacuum ha e fele. E ka ntšoa feela, ea ntšoa hape, ‘me ea tlatsoa ka sehatsetsing.

(6) Li-alarms tsa bohata tse bakoang ke mefokolo ea motlakase. Hobane relay ea tšireletso ea matla a phahameng e mongobo, ha e kopane hantle kapa e senyehile, yuniti ea boto ea elektronike e mongobo kapa e senyehile, ‘me ho hlōleha ha puisano ho baka alamo e fosahetseng. Bakeng sa mofuta ona oa phoso ea bohata, letšoao la phoso la HP letlapeng la elektronike hangata le tima kapa le khanya hanyenyane, relay ea tšireletso ea matla a phahameng ha e sebetse ka letsoho, k’homphieutha e bonts’a “HP RESET”, kapa e nyamela ka boeona, motlakase o sebetsang oa Compressor ke ntho e tloaelehileng, ‘me khatello ea ho hula le ho ntša metsi le eona e tloaelehile.
