Mafuta anoshandiswa pakuzora zvikamu zvinofamba mucompressor yekutonhodza anonzi mafuta ekutonhodza, anozivikanwawo semafuta ekuzora. Zvichienderana nezvinodiwa neMinistry of Petrochemical Industry, kune mafuta ekutonhodza akagadzirwa muChina muzvikamu zvishanu, zvinoti, Nhamba 13, Nhamba 18, Nhamba 25, Nhamba 30 uye Nhamba 40 yemutemo webhizinesi. Pakati pawo, mafuta ekutonhodza anoshandiswa zvakanyanya ndeaya Nhamba 13, Nhamba 18 uye Nhamba 25, macompressor eR12 anowanzo sarudza Nhamba 18, macompressor eR22 anowanzo sarudza Nhamba 25.
Mu compressor, mafuta efriji anonyanya kushandiswa pakuzora, kuvhara, kutonhora uye kutonga simba zvine mabasa mana.
(1) Kuzora mafuta
Oiri yemufiriji pakushanda kwekuzora compressor, kuitira kuderedza mwero wekukweshana uye kupera kwekushanda kwecompressor, nokudaro kuwedzera hupenyu hwekushanda kwecompressor.
(2) Kuvhara
Oiri yemufiriji inoita basa rekuvharira mucompressor, kuitira kuti piston yecompressor nepamusoro pesilinda, pakati pemabheyaringi anotenderera kuti zvibudirire, kudzivirira kubuda kwemvura mufiriji.
(3) Kutonhodza
Kana yakazorwa mafuta pakati pezvikamu zvinofamba zvecompressor, mafuta emufiriji anogona kubvisa kupisa kunobva panguva yekushanda, kuitira kuti zvikamu zvinofamba zvirambe zvichidziya, zvichiita kuti compressor ishande zvakanaka uye ivimbike.
(4) Kudzora simba
Kune compressor yekudziya ine nzira yekudzora simba, inogona kushandisa kumanikidzwa kwemafuta emufiriji sesimba remuchina wekudzora simba.
Kutanga, ndezvipi zvinodiwa zvemidziyo yekutonhodza pamafuta ekutonhodza
Nekuda kwekushandiswa kwezviitiko zvakasiyana uye mafiriji, michina yekufiriji pakusarudza mafuta ekufiriji haina kufanana. Zvinodiwa zvemafuta ekufiriji zvine zvinotevera:
1, kusviba
Hunhu hwemafuta ekunakisa mafuta mufiriji hunokosha, kushandiswa kwemafiriji akasiyana kusarudza mafuta ekunakisa akasiyana zvinoenderana. Kana viscosity yemafuta ekunakisa yakakura zvakanyanya, simba rekunakisa, kupisa kwekunakisa uye torque yekutanga inowedzera. Kusiyana neizvi, kana viscosity iri diki, zvichaita kuti kufamba pakati pezvikamu kusakwanise kuumba firimu remafuta rinodiwa, kuitira kuti zvisasvike pakunakisa uye kutonhora kunodiwa.
2, nzvimbo yekusviba
Nzvimbo yekusviba kwemafuta emufiriji ndeyekuti tembiricha inodzikiswa kusvika pamutengo wakati, mafuta emufiriji akatanga kupinza parafini, zvekuti mafuta ekuzora anova tembiricha yekusviba. Nzvimbo yekusviba kwemidziyo inoshandiswa mufiriji inofanira kunge yakaderera pane tembiricha yekubuda kwemvura mufiriji, zvikasadaro ichakonzera kuvharika kwevharuvhu yemagetsi kana kukanganisa mashandiro ekufambisa kupisa.
3, nzvimbo yekusimba
Mafuta emufiriji mumamiriro ekuyedza ekutonhodza kuti amise kuyerera kwetembiricha inozivikanwa senzvimbo yekutonhora. Midziyo yemufiriji inoshandiswa munzvimbo yekutonhora yemafuta emufiriji inofanira kunge yakaderera sezvinobvira (senge R22 compressor, mafuta emufiriji anofanira kunge ari pasi pe -55℃), zvikasadaro zvinokanganisa kuyerera kwe refrigerant, zvichiwedzera kuramba kuyerera, zvichikonzera kutamiswa kwekupisa kwakashata.
4, poindi yekupenya
Nzvimbo yekupenya yemafuta emufiriji ndiyo tembiricha yakaderera apo mafuta anopiswa kusvika panosvika utsi hwawo pahunobatidzwa nemurazvo. Midziyo yekudziya inoshandiswa mufiriji inofanira kunge yakakwira kupfuura tembiricha yekubuda kwemhepo ye15 ~ 30.℃kana kupfuura, kuitira kuti mafuta ekuzora asapiswe kana kupiswa.
5, kugadzikana kwemakemikari uye kuramba okisijeni
Mafuta ekuzora akachena akaumbwa nemakemikari akasimba, kwete oxidation, haazokanganisi simbi. Zvisinei, kana mafuta acho aine refrigerant kana mvura ichizogadzira ngura, oxidation yemafuta ichagadzira acid, ngura yesimbi. Kana mafuta acho akabatanidzwa pakupisa kwakanyanya, pachava necoke, kana zvinhu izvi zvakabatana nevharuvhu, zvichakanganisa mashandiro evharuvhu, panguva imwe chete zvichaita kuti vharuvhu ivharwe ne throttle. Saka, inofanira kusarudzwa nemakemikari akagadzikana uye oxidation resistance yakanaka.
6, hunyoro uye tsvina yemakanika
Kana mafuta ekuzora aine mvura, zvichawedzera kuchinja kwemakemikari mumafuta, zvekuti mafuta anoora, zvichikonzera ngura yesimbi, asiwo muvharuvhu yekuzora kana vharuvhu yekuwedzeredza zvinhu zvichikonzera "kuvharika kwechando". Mafuta ekuzora ane tsvina yemuchina, anowedzera kukweshana kwenzvimbo dzinofamba, uye nekukurumidza anovhara firita nevharuvhu yekuzora kana vharuvhu yekuwedzeredza zvinhu, saka mafuta ekuzora mufiriji haafanire kunge aine tsvina yemuchina.
7, mashandiro ekudzivirira kupisa
Mufiriji yakavharirwa zvishoma nezvishoma uye yakazara, mafuta ekuzora anotonhorera uye refrigerant zvinopindirana zvakananga uye mota uye zvinosangana, saka mafuta acho ane hunhu hwakanaka hwekuzora uye voltage yakakwira. Kushanda kwemafuta ekuzora akachena kwakanaka, asi ane mvura, tsvina neguruva, kushanda kwekudzivirira kunodzikira, zvinodiwa zvemafuta ekuzora anotonhorera anokwira kusvika 2.5KV kana kupfuura.
8, nekuda kwehunhu hwemhando dzakasiyana dzemafiriji, tembiricha yekushanda kwefiriji inosiyana zvikuru, mafuta efiriji anogona kusarudzwa nenzira iyi: mamiriro ekupisa akaderera, ekumhanya kwakaderera kwemidziyo yefiriji anogona kusarudzwa se viscosity, nzvimbo yekuomesa yakaderera yemafuta; uye mamiriro ekupisa anomhanya zvakanyanya kana emhepo anofanirwa kusarudzwa se viscosity, nzvimbo yekuomesa yakawanda yemafuta.
二、 Tsanangudzo yekushandiswa kwemafuta efriji yecompressor
1. HFC-134a (R-134a) air conditioning system pamwe neHFC-134a (R-134a) zvinongogona kushandisa mafuta emufiriji akatarwa chete. Mafuta emufiriji asina kudzorwa anokanganisa mafuta ecompressor, uye kusanganiswa kwemafuta emufiriji akasiyana-siyana kunogona kukonzera oxidation uye kutadza kwemafuta emufiriji, izvo zvinogona kukonzera kutadza kwecompressor.
2. HFC-134a (R-134a) inotaura kuti mafuta emufiriji anogona kupinza hunyoro kubva mumhepo nekukurumidza. Ndokumbirawo mutevedzere matanho anotevera:
(1) Pakupatsanura zvikamu zvefiriji kubva mumidziyo yefiriji, zvikamu zvacho zvinofanirwa kuvharwa (kuvharwa) nekukurumidza sezvinobvira kuderedza kupinda kwehunyoro mumhepo.
(2) Pakuisa zvikamu zvefiriji, musabvisa (kana kuvhura) chifukidziro chezvikamu musati mazvibatanidza. Ndapota batanidzai zvikamu zvefiriji nekukurumidza kuti muderedze kupinda kwehunyoro mumhepo.
(3) Mafuta akataurwa chete akachengetwa mumidziyo yakavharwa ndiwo anogona kushandiswa. Mushure mekushandisa, ndapota vharai mudziyo wekuzora nekukurumidza. Kana mafuta asina kuvharwa zvakanaka, haagone kushandiswazve mushure mekunge apinzwa nehunyoro.
3. Usashandise mafuta emufiriji akaora uye ane madhaka, sezvo zvichikanganisa mashandiro akajairika ecompressor.
4. Sisitimu iyi inofanira kuwedzera mafuta emufiriji zvichienderana nechiyero chakatarwa. Kana mafuta emufiriji ari mashoma zvakanyanya, zvinokanganisa mafuta ecompressor. Kuwedzera mafuta emufiriji akawandisa kuchakanganisawo kugona kutonhora kwemhepo inotonhodza.
5. Pakuwedzera refrigerant, mafuta erefrigerant anofanira kutanga awedzerwa, uye wozowedzera refrigerant
