Chosungiramo zoziziritsira chimatchedwa choziziritsira, chomwe ndi gawo lofunika kwambiri la makina oziziritsira mpweya pakati pa data. Refrigerant nthawi zambiri imakhala madzi, yotchedwa choziziritsira. Kuziziritsa kwa condenser kumachitika mwa kusinthana kutentha ndi kuziziritsa madzi otentha bwino, motero imatchedwanso chipangizo choziziritsira madzi. . Malo oziziritsira deta ali ndi kufunikira kwakukulu kwa mphamvu yozizira, ndipo kugwiritsa ntchito bwino mphamvu kungapezeke posankha chipangizo choziziritsira magetsi. Choziziritsira chomwe chili munkhaniyi chikutanthauza makamaka chipangizo choziziritsira magetsi.
Chokometsera choziziritsira cha centrifugal ndi chokometsera cha liwiro lozungulira. Chitoliro chokometsera chimalowetsa mpweya woti upanikizidwe mu cholowera cha impeller. Mpweya umazungulira mofulumira kwambiri ndi impeller pansi pa mphamvu ya masamba a impeller. Mpweya umagwira ntchito, liwiro la mpweya limawonjezeka, kenako umachotsedwa kuchokera ku chotulutsira cha impeller, kenako umalowetsedwa mu chipinda chotulutsira; popeza mpweya umatuluka mu impeller, uli ndi liwiro lalikulu la kuyenda, kuti usinthe gawo ili la liwiro kukhala mphamvu yokakamiza, chokometsera cha A chokhala ndi gawo loyenda pang'onopang'ono chimayikidwa kuti chisinthe mphamvu kuti chiwonjezere kuthamanga kwa mpweya; mpweya wofalikira utasonkhanitsidwa mu volute, umalowa mu condenser ya unit kuti ukhale ndi condensation. Njira yomwe ili pamwambapa ndi centrifuge. Mfundo ya kukanikiza, monga momwe zasonyezedwera pa Chithunzi 1; Kuphatikiza apo, kuti zipangitse kuzizira ndikuchotsa kuzizira, makina oziziritsira mpweya amaphatikizapo makina oziziritsira madzi ndi makina ozizira amadzi.

Kapangidwe ka gawo la Centrifugal
Kapangidwe ka gawo la centrifugal ndi motere: kuphatikiza compressor ya centrifugal, evaporator, condenser, throttling orifice, chipangizo choperekera mafuta, kabati yowongolera, ndi zina zotero, monga momwe zasonyezedwera pa Chithunzi 2 ndi Chithunzi 3. Compressor imapangidwa makamaka ndi chipinda chokoka, impeller, diffuser, bend ndi reflux device, ndi volute.
Makhalidwe a chipangizo cha centrifugal
Makhalidwe a chipangizo chachikulu cha centrifuge ndi awa:
1. Mphamvu yayikulu yoziziritsira. Popeza mphamvu yoyamwa ya compressor ya centrifugal singakhale yaying'ono kwambiri, mphamvu yoziziritsira ya single-unit ya compressor ya centrifugal ndi yayikulu pang'ono. Kapangidwe kakang'ono, kulemera kopepuka komanso kakang'ono, kotero imakhala ndi malo ochepa. Pansi pa mphamvu yomweyo yoziziritsira, kulemera kwa compressor ya centrifugal ndi 1/5 mpaka 1/8 yokha ya ya compressor ya piston, ndipo mphamvu yoziziritsira ikakhala yayikulu, imakhala yowonekera bwino.
2. Zida zochepa zogwiritsidwa ntchito komanso zodalirika kwambiri. Ma compressor a centrifugal sagwiritsidwa ntchito nthawi zonse, kotero ndi olimba ndipo ali ndi ndalama zochepa zosamalira ndi kugwiritsa ntchito.
3. Gawo lokakamiza mu compressor ya centrifugal ndi lozungulira, ndipo mphamvu ya radial ndi yolinganizidwa, kotero ntchitoyo ndi yokhazikika, kugwedezeka ndi kochepa, ndipo palibe chipangizo chapadera chochepetsera kugwedezeka chomwe chikufunika.
4. Mphamvu yoziziritsira imatha kusinthidwa pang'ono. Ma compressor a centrifugal amatha kugwiritsa ntchito njira monga kusintha kwa vane yotsogolera kuti asinthe mphamvu mkati mwa mtunda winawake.
5. N'zosavuta kugwiritsa ntchito kukanikiza ndi kutsekereza zinthu m'magawo ambiri, ndipo zimatha kugwira ntchito ndi kugwirira ntchito firiji imodzi yokhala ndi kutentha kosiyanasiyana.
Zolakwika Zofala za Ma Chillers
Makina ozizira adzakumana ndi mavuto ena panthawi yomanga ndi kuyimitsa ntchito, ndipo kulephera kudzachitikanso panthawi yogwira ntchito. Kuthana ndi mavuto ndi zolakwika izi kukugwirizana ndi chitetezo cha ntchito ndi kukonza malo osungira deta. Izi ndi zina mwazochitika zomwe zinachitika panthawi yomanga ndi kugwiritsa ntchito makina ozizira. Njira zoyenera zogwirira ntchito ndi zokumana nazo ndizongogwiritsidwa ntchito.
01
Palibe kukonza zolakwika pa katundu
【Vuto lachilendo】
Malo osungira deta ayenera kukonza zolakwika ndikuyesa kuyendetsa chiller, koma kukhazikitsa zida zoziziritsira mpweya sikunamalizidwe, ndipo malowo alibe zinthu zofunikira, kotero ntchito yoyambitsa siingachitike.
【kusanthula mavuto】
Pambuyo poti makina oyeretsera magetsi akhazikitsidwe mu malo osungira deta atsekedwa, zida zoyeretsera zamagetsi mu chipinda cha makompyuta sizinaikidwe, njira yoziziritsira madzi pa malo osungira madzi imatsekedwa, ndipo choyeretsera magetsi sichingathe kukonzedwa. Katunduyo ndi wochepa kwambiri kuti afike pamlingo wotsika wa choyeretsera, ndipo ntchito yokonza makina singathe kuchitika. Kumbali ina, chifukwa makina ozizira sanakonzedwe, zida za seva mu chipinda chachikulu cha makompyuta sizingathe kuyatsidwa ndikuyenda, ndikupanga kuzungulira kosatha pakati pawo; kuphatikiza apo, panthawi yokonza makina, mphamvu yofunikira yamagetsi ndi yayikulu, ndipo njira yogwirira ntchito idzagwiritsa ntchito mphamvu zambiri; zinthu zomwe zili pamwambapa zimapangitsa kuti makina ozizira akonzedwe.
【vuto lathetsedwa】
Gwiritsani ntchito njira yochotsera kutentha popanda kunyamula katundu pochotsa kutentha. Njirayi ndikugwiritsa ntchito mokwanira mphamvu yosinthira kutentha ya plate exchange, kusinthana kuzizira komwe kumapangidwa ndi evaporator ya firiji kupita kumbali ya condenser ya firiji kudzera mu plate exchange, ndikusinthirana kutentha komwe kumatulutsidwa ndi condenser ya firiji kubwerera kumbali ya evaporator kudzera mu plate exchange, kuti pakhale mgwirizano wathunthu pakati pa mphamvu yoziziritsira ya friji ndi katundu wotentha, ndipo nsanja yoziziritsira imangochotsa mphamvu ya shaft ya compressor. Pogwiritsa ntchito njira iyi, ndikosavuta kukwaniritsa mayeso ogwirira ntchito pansi pa katundu wosiyanasiyana. Kuzungulira kwa madzi kwa cold plate replacement ndi debugging kukuwonetsedwa pa Chithunzi 4.
Njira zochotsera zolakwika za dongosolo ndi izi:
1. Tsegulani valavu yodutsa mu sub-collector, ndikuwonetsetsa kuti njira yamadzi yatsegulidwa kuti ipange kayendedwe ka madzi pamene choziziritsira mpweya sichinakhazikitsidwe;
2. Tsegulani bwino chiller kumbali ya madzi ozizira ndi valavu yosinthira mbale kuti muwonetsetse kuti njira ya madzi yosinthira chiller ndi mbale ndi yosalala, ndipo madzi ozizira omwe amakokedwa ndi chiller ndi kutentha komwe kumabwezedwa ndi chiller zitha kusakanikirana bwino; nthawi zambiri tsegulani pampu yamadzi ozizira ndikusintha ma frequency pamanja kukhala 45Hz kapena kuposerapo, ndikuwonetsetsa kuti kuyenda kwa madzi kuli bwino;
3. Tsegulani bwino valavu yamadzi ozizira ya chiller, tsegulani pang'ono valavu yomwe ili kumbali yamadzi ozizira ya chosinthira panelo, ndikuyatsa pampu yamadzi ozizira kuti muwonetsetse kuti madzi akuyenda bwino. Sinthani pafupipafupi ya pampu kukhala 41-45Hz; musayatse fan ya nsanja yozizira kaye;
4. Mu madzi ozizira ndi madzi ozizira, yatsani choziziritsira ndikuchita ntchito yoyesera yokha;
5. Kutentha kwa madzi ozizira kwa chitofu kumayamba kukwera, ndipo madzi ozizira akuyamba kuzizira;
6. Sinthani mphamvu yosamutsira kutentha kwa malo osinthira mbale malinga ndi kutseguka kwa valavu yamadzi ozizira ya malo osinthira mbale, ndikusintha kutseguka kwa valavu pakati pa 1/4 ndi kutseguka kwathunthu;
7. Yatsani pang'ono fani ya nsanja yoziziritsira malinga ndi kutentha kwa madzi ozizira, chilichonse chomwe chingachotse mphamvu ya shaft ya compressor.
【Zokumana nazo】
Pofuna kuchepetsa kugwiritsa ntchito mphamvu moyenera komanso kuganizira za kuziziritsa kwachilengedwe, malo osungira deta nthawi zambiri amapangidwa ndi ukadaulo woziziritsa tower + plate replacement. Pa nthawi yokhazikitsa, mphamvu yosinthira kutentha ya plate exchange ingagwiritsidwe ntchito kupeza kutentha kokwanira kuchokera ku condenser ya chiller chifukwa kutentha komwe kumayikidwa kuti chiller igwire ntchito, ndiko kuti, kuzizira komwe kumapangidwa ndi chiller kumachotsedwa ndi plate exchange.
Mfundo yothetsa vuto la kutentha popanda kunyamula katundu ndikugwiritsa ntchito mokwanira mphamvu yosinthira kutentha ya mbale yosinthira, kusinthana kuzizira komwe kumapangidwa ndi evaporator ya firiji kupita kumbali ya condenser ya firiji kudzera mu mbale yosinthira, ndikusinthirana kutentha komwe kumatulutsidwa ndi condenser ya firiji kubwerera ku evaporator kudzera mu mbale yosinthira, kuti akwaniritse kufananiza mphamvu yoziziritsira ndi kutentha kwa firiji, njira iyi ndi yosavuta kugwiritsa ntchito komanso yosavuta kuyigwiritsa ntchito.
