Mamwe ma screw chiller anoda kuzadzwa nefiriji panzvimbo yemushandisi, uye huwandu hwekuzadza hwefiriji uye giredhi refiriji hunofanirwa kuenderana nemirairo.Kusakwana refrigerant charge.zvichaguma nekusatonhodza kwakakwana.Yakawandisa refrigerant charge haingo wedzera mari chete, asi inogonawo kuva nemhedzisiro yakaipa pakushandisa simba rekushandisa.
Firiji yakakwana inofanira kugadzirirwa pachine nguva isati yachaja firiji.Paunenge uchizadza, inogona kuzadzwa zvakananga kubva kune yakakosha valve yekuzadza.Sezvo sisitimu iri muvacuum state, mutsauko wekumanikidza pakati pefiriji mucylinder uye system yakakura.Kana iyo valve yakavhurwa (mhepo iri mupombi yekubatanidza inofanira kubudiswa kunze nefiriji kutanga, kuitira kudzivirira mhepo kupinda muchikwata uye kukanganisa kushanda kwechikwata), firiji inokurumidza kusunungurwa kubva muhumburumbira.Mushure mokuzadza hurongwa, valve yekuzadza inofanira kuvharwa kutanga, uye ipapo pombi yekubatanidza inofanira kubviswa.
Kana kupisa kwekupisa kwe condenser kwakashata, iyo compressor inoshanda yakaderera uye kushanda ikozvino kunowedzera.Kana mweya wakatonhodzwa mukuru-pressure pressure ichikwira kusvika 24kg/cm2, uye mvura-yakatonhodzwa high-pressure pressure ichikwira kusvika 20kg/cm2, compressor inodzorwa nehigh-pressure switch protection, uye compressor inomira Operation, kusapisa kwakashata. disipation, high pressure overload uye kodhi yekukanganisa kana chiratidzo chekutadza chinoratidzwa.Panguva ino, ndapota tarisai kana mvura inotenderera yeshongwe yekutonhodza yakajairika, kana tembiricha yemvura inotonhorera yakakwira zvakanyanya, kana pombi yekutonhodza fan fan iri kushanda, uye kana vharuvhu yemvura inotonhorera yakavhurwa zvizere (ndapota tarisa kuti shongwe yekutonhodza yakazaruka zvizere).Kunyangwe radiator yakasviba kana kuvharika), dzvanya bhatani reset mushure mekunge zviri pamusoro zvakajairika, kana kudzima uye wotanga kushanda zvakajairika.Kana high pressure overload ichiitika kakawanda, ndapota ronga kuchenesa condenser nekukurumidza sezvazvinogona.
Iyo yakajairika chiyero chekushanda kwescrew chiller inofanirwa kusangana nemapoinzi anotevera:
1. Kupisa kwemafuta e compressor inenge 40-55 ℃;
2. Kupisa kwekushisa kwe compressor ndeye 45-90 ℃, uye tembiricha yepamusoro haifaniri kudarika 1.05 ℃;
3. The exhaust pressure of compressor is 1.8～1.47MPa (gauge pressure);
4. Kumanikidzwa kwemafuta e compressor ndeye 0.2～0.3MPa (gauge pressure);
5. Panguva yekushanda kwe compressor, inzwi rinofanira kunge rakafanana uye rakagadzikana, uye hapafaniri kuva nezwi risinganzwisisike;
6. Iyo tembiricha yekubuda kweiyo unit inofanira kunge iri 3-4 ℃ yakaderera pane yekubuda tembiricha yemvura yefiriji, uye tembiricha yekubuda kwemvura yefiriji kazhinji inenge 5-7 ℃;
7. Kupisa kwekushisa kwechikwata kunofanira kuva 3-5 ℃ yakakwirira kudarika tembiricha yemvura inotonhorera;iyo inotonhora danda uye tembiricha zvinofanirwa kudzorwa paanenge 40 ℃, uye condenser inlet tembiricha yemvura inofanira kunge iri pasi pe32 ℃.
Kunze kwekunze kwekuchengeterwa kunotonhora kwakabatanidzwa:
Chenesa nemvura yakapfava uye inodziya kuchengetedza kupera kwepamusoro, usashandise abrasive cleaners kana abrasive pads pakukwesha.
Nzvimbo yemukati yekuchengetera inotonhorera yakasanganiswa:
Shandisa mishonga yekuchenesa imba, amino cleaners uye detoxification solutions kuchenesa mukati, izvo zvisingazokanganise pamusoro , Usasasa mvura pane zvikamu zvemagetsi, usashandise solvent, mafuta kana asidi yekuchenesa.
Classification ye screw chillers:
1. Maererano nebasa rekugadzirisa mhepo, rakakamurwa kuva imwe chete inotonhorera rudzi uye kupisa pombi yemhando.
2. Maererano nemafiriji akasiyana-siyana anoshandiswa, akakamurwa kuva marudzi maviri: R134a uye R22.
3. Maererano nemaitiro ayo ekugadzirisa, yakakamurwa mumvura-yakatonhorera screw chiller uye air-cooled screw chiller!
4. Zvinoenderana nechisimbiso chimiro che compressor, yakakamurwa kuva yakavhurika mhando, semi-yakavharwa mhando uye yakazara yakavharwa mhando.
5. Zvinoenderana nechimiro cheiyo evaporator, inogona kukamurwa kuva yakajairika mhando uye mafashama emhando.
6. Zvinoenderana neakasiyana screw refrigeration compressors anoshandiswa muscrew chiller, inokamurwa.Screw refrigeration compressors yakakamurwa kuita marudzi maviri: mapatya-screw uye single-screw.Twin-screw refrigeration compressors ine peya yemarotor ane mazino ehelical anogeda akatarisana.Iyo single-screw refrigeration compressor ine rotor screw ine 6 helical grooves yakagadziriswa pamusoro wekunze cylindrical.Kune chaiwo magiya epuraneti ane marekeni gumi nerimwe akaiswa mudenga kuruboshwe nekurudyi kweshavishavi netsvimbo!Kunzwisisa kwakadzama kwekugadzika kwe screw chiller pasina mubvunzo kune rubatsiro rwakakura kushamwari dzinoda kutenga screw chiller!
Maverengero maitiro:
1: Vhoriyamu (marita) × nhamba yemarita ekushisa ÷ nguva yekudziya (maminitsi) × 60 ÷ 0.86 (coefficient) = (W)
2: Vhoriyamu (matani kana cubic metres) × nhamba yemalita ekushisa ÷ nguva yekudziya (maawa) ÷ 0.86 (coefficient) = (KW) kana ukaunza data rako, unogona kuwana maawa mana 10000L×(15-7)÷ 4h÷0.86=23255W =23.255KW maawa mashanu 10 matani×(15-7)÷5h÷0.86=18.604KW
