• Usambofa wakasiya silinda yekuzadza yakabatana nedunhu.

Verification isati yatumwa

• Shandisa zvigadziriso zvekuchengetedza senge kuchengetedza kudzvanywa chinja uye mechaniki yekuyamura vharafu mukuteerana neyakajairwa uye munharaunda inoshanda mirau uye kuchengetedza zviyero.
• Ita shuwa kuti ari kushanda uye akaiswa nemazvo.
• Tarisa kuti marongero e-high-pressure switch uye mavharuvhu ekuyamura haapfuure iyo yakanyanya kumanikidza sevhisi yechero chikamu chehurongwa.
• A low-pressure switch inokurudzirwa kudzivirira kushanda kwevacuum. Minimum setting ye 0.22 bar g.
• Wona kuti kubatanidza kwemagetsi kwese kwakanyatso kusungirirwa uye zvinoenderana nemitemo yenzvimbo.
• Kana heater yecrankcase ichidikanwa, inofanirwa kusimbiswa kwemaawa angangoita gumi nemaviri isati yatanga uye kutanga-mushure mekuvharwa kwenguva refu kwemabhandi emhando ye crankcase heaters.

Tanga

Usambofa washandisa compressor isina chivharo chebhokisi remagetsi rakaiswa.

• Usambofa watanga compressor kana pasina firiji inobhadhariswa.
• Ese mavharuvhu ebasa anofanira kunge ari munzvimbo yakavhurika.
• Balance iyo HP/LP pressure.
• Ipa simba compressor. Inofanira kutanga nokukurumidza. Kana iyo compressor ikasatanga, tarisa kuenderana kwe wiring uye voltage pamaterminals.
• Pakupedzisira reverse rotation inogona kuonekwa nekutevera zviitiko; iyo compressor haivake kumanikidza, ine yakakwira isinganzwisisike mwero uye yakaderera yakaderera simba rekushandisa. Mumamiriro ezvinhu akadaro, vhara compressor pakarepo uye batanidza zvikamu kune avo chaiwo materminals. DSG compressors inodzivirirwa kubva kune reverse kutenderera neyekunze yekudzivirira yemagetsi module. Vanozodzima otomatiki.
• Ini kana iyo yemukati yekuyamura vharafu yakavhurwa iyo compressor sump ichadziya uye iyo compressor inodonha ichibuda pamudziviriri wemota.

Tarisa nekumhanya compressor

• Tarisa ikozvino dhirowa uye voltage.
• Tarisa suction superheat kuti uderedze njodzi yekutsvedza.
• Tarisa huwandu hwemafuta mugirazi rekuona kweanenge maminetsi makumi matanhatu kuti uve nechokwadi chekuti mafuta akakwana adzokere kune compressor.
• Remekedza miganhu yekushandisa.
• Tarisa machubhu ese kuti ane kudengenyeka kusingaite. Kufamba kunopfuura 1.5 mm kunoda matanho ekugadzirisa akadai semabhuraketi echubhu.
• Pazvinenge zvichidikanwa, imwe firiji muchikamu chemvura inogona kuwedzerwa mudivi rekudzvanya-kudzvinyirira kusvika kure sezvinobvira kubva kune compressor. Iyo compressor inofanirwa kunge ichishanda panguva iyi.
• Usabhadharise system yacho zvakanyanya.
• Usambofa wakasunungura refrigerant kumhepo.
• Kune anodzoreredzwa masisitimu, ita shuwa kuti 4-nzira vharafu haidzokeri kana compressor yamiswa nekuda kwekudziya kana kutonhora kudiwa (mira pane thermostat)
• Usati wasiya saiti yekuisa, ita ongororo yekumisikidza yakajairika maererano nehutsanana, ruzha uye kuona kuvuza.
  Rekodha mhando uye huwandu hwefiriji yekuchaja pamwe nemamiriro ekushanda sereferensi yekuongorora mune ramangwana.

Maintenance

• Kumanikidzwa kwemukati uye tembiricha yepasi zvine njodzi uye zvinogona kukonzera kukuvara zvachose. Maintenance operators uye installers vanoda unyanzvi hwakakodzera uye maturusi. Tembiricha yeTubing inogona kudarika 100°C uye inogona kukonzera kupisa kwakanyanya.
• Ita shuwa kuti nguva nenguva yekuongorora sevhisi kuona kuvimbika kwehurongwa uye sezvinodiwa nemirairo yenzvimbo inoitwa.
  Kudzivirira matambudziko ane chekuita necompressor system, kutevedzera periodic kugadzirisa kunokurudzirwa:
• Ona kuti midziyo yekuchengetedza iri kushanda uye yakasetwa nemazvo.
• Ita shuwa kuti system yacho yadonha yakasimba.
• Tarisa iyo compressor ikozvino dhirowa.
• Simbisa kuti sisitimu iri kushanda nenzira inoenderana nemarekodhi ekugadzirisa ekare uye mamiriro ekunze.
• Tarisa kuti kubatanidza kwemagetsi kwese kuchiri kusungirirwa zvakakwana.
• Chengetedza compressor yakachena uye simbisa kusavapo kwe ngura uye oxidation pane compressor shell, machubhu uye magetsi ekubatanidza.

Warranty

Gara uchiendesa iyo modhi nhamba uye serial nhamba nechero kuda filed maererano nechigadzirwa ichi. Chigadzirwa waranti inogona kushaya muzviitiko zvinotevera:
