Kukwanisa kutonhora hakugone kuzadzisa zvinodiwa zvemutoro wemudura
(kushanda zvakanaka kwecompressor)
Pane zvikonzero zviviri zvikuru zvinoita kuti pasave nekupararira kweropa mufiriji.
Chekutanga, muripo wemufiriji hauna kukwana, uye huwandu hwakakwana hwemufiriji hunodiwa panguva ino;
Chimwe chikonzero ndechekuti kune maburi akawanda emuchina we refrigerant. Kuti ugadzirise dambudziko iri, unofanira kutanga wawana panobuda mvura, wotarisa pakubatanidza mapaipi ese nevharuvhu, wozozadza refrigerant yakakwana mushure mekugadzirisa zvikamu zvakabuda mvura.
Kushaikwa kwekukwanisa kutonhora
(Huwandu hwe refrigerant hushoma mu system)
Kusakwana kwe refrigerant mu system kunokanganisa zvakananga kufamba kwe refrigerant mu evaporator. Kana kuvhurwa kwe expansion valvu kwakanyanya kukura, expansion valvu hakugadziriswi kana kuvharwa zvisina kunaka. Refrigerant flow rate yakakura, evaporation pressure ne evaporation tembiricha zvinowedzerawo, uye tembiricha yekudonha kwe evaporation mu warehouse inodzikira; panguva imwe chete, kana expansion valvu ikavhurwa diki kana kuti yakavharika, refrigerant flow rate inodzikirawo, uye kutonhora kwe system kunowedzerawo nekudzikira kwe warehouse tembiricha inodzikirawo. Kazhinji, zvinogona kutariswa kana refrigerant flow rate ye expansion valve yakakodzera nekuona evaporation pressure, evaporation tembiricha uye frosting condition ye suction pipe. Expansion valve blockage chinhu chakakosha chinokanganisa refrigerant flow. Zvikonzero zvikuru zve expansion valve blockage i ice blockage uye tsvina blockage. Ice blockage imhaka yekuti dryer dryer haina kunaka, uye refrigerant ine hunyoro. Kana ikayerera nepavharuvhu yekutambanudza, tembiricha inodzikira pasi pe0 °C, uye hunyoro huri mufiriji hunooma kuita chando uye hunovhara buri revharuvhu yekudzora; kuvharika kwakasviba kunokonzerwa nekuti pane tsvina yakawanda yakaungana pachidzitiro chefirita panzvimbo inopinzwa vharuvhu yekutambanudza, uye firiji haina kutsetseka uye yakatsetseka, zvichikonzera kuvharika.
Kuyerera kwemufiriji kwakakura zvakanyanya kana kuti kudiki zvakanyanya
(kugadziriswa kusina kunaka kana kuvharika kwevharuvhu yekuwedzera)
Kuwanda kwemafuta anodziya mukati nekunze kwechubhu inodziya ye evaporator kunodzikira, kana mafuta anodziya abatanidzwa mukati nekunze kwechubhu inodziya ye evaporator. Saizvozvowo, kana paine mhepo yakawanda muchubhu inodziya, nzvimbo inodziya ye evaporator inodzikira, kushanda kwekupisa kunodzikirawo zvakanyanya, uye mwero wekudonha kwekupisa kwedura unodzikira. Saka, mukushanda nekuchengetedza kwezuva nezuva, kunofanira kutariswa kubviswa kwemavanga emafuta mukati nekunze kwechubhu inodziya ye evaporator uye kuburitswa kwemhepo mu evaporator kuti pave nekushanda kwe evaporator.
Kuderedzwa kwekushandiswa kwekupisa
(Muchina we evaporator mune mhepo yakawanda kana mafuta ekutonhodza)
Izvi zvinonyanya kuitika nekuti chando chiri kunze kwe evaporator chakakora zvakanyanya kana kuti guruva rakawandisa. Nekuti tembiricha yekunze ye evaporator mu cold storage inonyanya kuderera pane 0 ℃, chimwe chikonzero chakakosha chekudzikira kwekupisa kwekuchengetedza inyaya yekuti evaporator haishandise kupisa zvakanyanya. Hunyoro hwemudura hwakakwira zvakanyanya, uye hunyoro mumhepo huri nyore kuomesa kana kutoita kuti iome pamusoro pe evaporator, izvo zvinokanganisa mafambiro e evaporator pakupisa. Kuti chando chekunze che evaporator chisanyanya kukobvu, chinofanira kunyungudutswa nguva nenguva.
Heano nzira mbiri dziri nyore dzekunyungudutsa chando:
① Mira kuti unyungudike. Kureva kuti, misa kushanda kwecompressor, vhura gonhi reimba yekuchengetera zvinhu, rega tembiricha yeimba yekuchengetera zvinhu ikwire, wotangazve compressor mushure mekunge chando chanyunguduka chega.
②Chong cream. Mushure mekubvisa zvinhu mudura, sukurudza zvakananga pamusoro pepombi ye evaporator nemvura yepombi ine tembiricha yakakwira kuti inyungudike kana kudonha kubva pachando. Pamusoro pekusagona kutamisa kupisa kwe evaporator nekuda kwechando chakakora, pamusoro pe evaporator pakanyanya kukobvu nekuda kwekusvibiswa kwenguva pfupi, uye kushanda kwayo kwekutamisa kupisa kuchadererawo zvakanyanya.
Kuderedzwa kwekushandiswa kwekupisa
(Pamusoro pemuchina we evaporator pakaoma zvakanyanya kana kuti pakaita guruva rakawandisa)
Kusasimba kwekupisa uye kushaya simba kwekupisa, uye kusashanda zvakanaka kwekupisa kunokonzerwa nekusakwana kweukobvu hwezvikamu zvekupisa zvakaita semapaipi nemadziro ekuchengetedza kupisa. Izvi zvinonyanya kukonzerwa nekusasarudzwa kusina kunaka kweukobvu hwezvikamu zvekupisa panguva yekugadzira kana kushaya kunaka kwezvinhu zvekupisa panguva yekuvaka.
Pamusoro pezvo, panguva yekuvaka nekushandisa, kuputira kwekupisa uye basa rinodzivirira hunyoro hwezvinhu zvinoputira kupisa zvinogona kukuvara, zvichiita kuti jira rinoputira kupisa rive rakanyorova, rakakanganisika, kana kutokukurwa.
Chimwe chikonzero chakakosha chekurasikirwa kukuru kwekutonhodza ibasa risina kunaka rekuvharira, uye mhepo inopisa yakawanda inopinda mudura kubva pakubuda kwemvura. Kazhinji, kana paine kunyorova padanda remusuwo wedura kana chisimbiso chemadziro ekudzivirira kutonhora, zvinoreva kuti chisimbiso hachina kusimba.
Pamusoro pezvo, kuvhurwa nekuvharwa kwegonhi remudura nguva nenguva kana vanhu vakawanda vanopinda mudura pamwe chete kunowedzerawo kurasikirwa kwesimba rekutonhodza mudura. Gonhi redura rinofanira kudzivirirwa kuti risavhurike zvakanyanya kudzivirira mhepo inopisa yakawanda kuti isapinde mudura. Ehe, kana dura richigara rakachengetwa kana kuti stock yakakura zvakanyanya, kupisa kunowedzera zvakanyanya, uye kazhinji zvinotora nguva yakareba kuti dzitonhore kusvika patembiricha yakatarwa.
zvinotungamirira pakurasikirwa kukuru kwekutonhora
(nzvimbo inotonhorera nekuda kwekusapisa zvakanaka kwekupisa kana kushanda zvakanaka kwekuvhara)
Zvinhu zvakaita sema cylinder liners nema piston rings zvakasakara zvakanyanya, uye compressor iri kushanda kwenguva pfupi. Kana nzvimbo yekubvumidza ikawedzera, mashandiro ekuvharira achadzikira zvinoenderana, gas transmission coefficient ye compressor ichadzikirawo, uye kutonhora kuchadzikira. Kana kutonhora kuri pasi pekupisa kwewarehouse, tembiricha yewarehouse ichadzikira zvishoma nezvishoma. Kugona kutonhora kwe compressor kunogona kutsanangurwa nekutarisa kusveta nekuburitsa simba kwe compressor. Kana kutonhora kwe compressor kuchidzikira, nzira inowanzoshandiswa ndeyekutsiva cylinder liner ne piston ring ye compressor. Kana kutsiva kuchiri kushanda, zvimwe zvinhu zvinofanirwa kufungwa nezvazvo, kana kutoputsa nekuongorora kuti pasave ne fault fault fault factors.
