Kusarudzwa kwemafuta efriji
Imwe ndeyechinyakare mineral oil;
Imwe yacho inogadzirwa polyethylene glycol esters yakadai sePO,Polyester mafuta inogadzirwawo polyethylene glycol lubricating oil.POE mafuta inogona kushandiswa kwete muHFC refrigerant system chete, asiwo muhydrocarbon refrigerant.PAG mafuta inogona kushandiswa muHFC, hydrocarbon uye ammonia. masisitimu semafiriji.
Basa guru refiriji mafuta
·Deredzai friction work, friction heat uye kupera
·Zadza nzvimbo yekuisa chisimbiso nemafuta kuti uve nechokwadi chekuisa chisimbiso uye kudzivirira kubuda kwefiriji.
·Kufamba kwemafuta kunobvisa twumabrasive particles anogadzirwa nesimbi friction, nokudaro kuchenesa nzvimbo yekukwenya.
·Ipa hydraulic simba rekuburutsa michina
Performance zvinodiwa pafiriji mafuta
· Yakakodzera viscosity: iyo viscosity yefiriji yemuchina mafuta haingoiti chete kuti friction pamusoro peimwe neimwe inofamba ine lubricity yakanaka, asi zvakare inobvisa kumwe kupisa kubva kumushini wefiriji uye inoita basa rekuvhara. yekunyungudika kukuru kumafuta emuchina wefiriji, mafuta ane viscosity yakakwirira anofanirwa kutariswa kukunda simba remafuta akacheneswa nefiriji.
‣ Diki inovhuvhuta, yakakwira flash point: kutonhora kwemafuta ekupisa huwandu hwakakura, pamwe nefiriji kutenderera, huwandu hwemafuta huri, zvakanyanya saka zvikamu zvemafuta efiriji chikamu chakatetepa kwazvo cheflash point inofanirawo kunge yakakwira kupfuura tembiricha yekubuda nemuchina pamusoro pe25 ~ 30. ℃.
Kugadzikana kwekemikari yakanaka uye kugadzikana kwemafuta oxidation: mune yekupedzisira compression yefiriji muchina unoshanda tembiricha ndeye 130 ℃ ~ 160 ℃, tembiricha yemafuta akaomeswa kupisa uye kuora kwekugara metamorphism, gadzira kabhoni dhipoziti mufiriji kusashanda zvakanaka kwemuchina uye kupera. Uyezve, kuora. zvigadzirwa zvemafuta zvichabata nefiriji, izvo zvichaita kuti kutonhora kuwedzere, uye iyo inoguma asidhi ichaita corrode zvakasimba zvikamu zvefiriji.
· Hapana mvura uye tsvina: nokuti mvura inotonhora mu evaporator inokanganisa kupisa kwekushisa, kusangana nefiriji kunowedzera kuparara kwefiriji uye kunopisa midziyo, saka mafuta efiriji haagoni kuva nemvura uye tsvina.
•Zvimwe:Oiri yefiriji inofanirawo kunge iine chinhu chakanaka chekudzivirira kupupa uye kwete kunyungudika kana kuwedzera kuita rabha, waya ine enameled nezvimwe zvinhu.Kuvharisa kwemagetsi kwakanaka kunofanira kushandiswa muchina wakavharirwa firiji.
Zvinhu zvekufunga nezvazvo pakusarudza mafuta efiriji
·Viscosity: iyo yakakwirira kumhanya kwe compressor, iyo yakakwirira viscosity yemafuta efiriji inofanira kunge iri.
·Thermal stability:Kudzikama kwemafuta kunowanzoyerwa neflash point yemafuta einjini yakaomeswa nechando.Flash point inoreva tembiricha apo chiutsi chemafuta emuchina wefiriji chinopenya kana chapiswa.Flash point yemafuta emufiriji inofanira kunge yakakwira kudarika iyoyo. ye compressor exhaust tembiricha, senge R717, R22 compressor uchishandisa firiji mafuta flash point inofanirwa kunge iri pamusoro pe160 ℃.
· Fluidity: mafuta emuchina wefiriji anofanirwa kuve nekuyerera kwakanaka pakudziya kwakaderera.Mune evaporator, nekuda kwekuderera kwekushisa uye kuwedzera viscosity yemafuta, iyo fluidity ichave yakashata.Kana iyo firiji yemuchina mafuta inosvika kune imwe tembiricha, inomira kuyerera.Iyo inotonhora yefiriji yemuchina mafuta inodiwa kuve yakaderera, kunyanya kutonhora kwemafuta emushini we cryogenic kunokosha zvakanyanya.
·Solubility: kunyungudika kwemafiriji akasiyana-siyana nemafuta emufiriji kwakasiyana, ayo anogona kukamurwa kuita zvikamu zvitatu: imwe hainyungudika, imwe isinganyungudike, uye imwe iri pakati pezviviri zviri pamusoro.
·Turbidity point: tembiricha apo mafuta emufiriji anotanga kunayisa parafini (oiri inoita turbid) inonzi turbidity point.Kana refrigerant iripo, turbidity point yemafuta efiriji inoderera.
Chikonzero chikuru chekuora kwemafuta efiriji
·Kusanganisa mvura: nekuda kwekupinda kwemhepo mufiriji system, mvura iri mumhepo inosanganiswa nemafuta emuchina wefiriji mushure mekusangana.Mvura yemvura iri mufiriji yakakwirira, inogonawo kusanganisa mvura mumafuta efiriji.Kana mvura inosanganiswa mufiriji. mafuta efiriji, viscosity inoderera uye simbi yakasvibiswa.Mu freon refrigeration system, "ice plug" inokonzerwawo.
·Oxidation: kana mafuta efiriji achishandiswa, kana tembiricha yekubuda kwecompressor yakakwira, inogona kukonzera kuderera kweoxidative, kunyanya mafuta efiriji asina kugadzikana kwemakemikari, ayo anowanzo shatisa.Nekufamba kwenguva, zvisaririra zvichaumbwa mumafuta efiriji, zvichiita kuti mafuta ekuzora uye dzimwe nzvimbo adzike.Kusanganiswa kwemafuta ekuzadza uye kusvibiswa kwemagetsi mumafuta emuchina wefiriji kuchawedzerawo kuchembera kwayo kana oxidation.
Kusanganiswa kwemafuta emuchina wefiriji: kana mhando dzakasiyana dzemafuta emuchina wefiriji dzichishandiswa pamwechete, viscosity yemafuta emuchina wefiriji inoderedzwa, uye kunyange kuumbwa kwefirimu remafuta kuchakuvadzwa.
Kana marudzi maviri emafuta emuchina wefiriji aine akasiyana anti-oxidation ekuwedzera ezvivakwa zvakasiyana, kana akasanganiswa pamwe chete, shanduko yemakemikari inogona kuitika uye mvura inonaya ichaumbwa, izvo zvinozokanganisa mafuta e compressor.Naizvozvo, kutarisisa kunofanirwa kubhadharwa kana uchishandisa.
Mumafuta efiriji mune tsvina
Nzira yekusarudza mafuta efiriji
·Sarudza mafuta ekuzora zvinoenderana nerudzi rwekumanikidza: compressor yemuchina wefiriji ine marudzi matatu episton, screw uye centrifugal.Mhando mbiri dzekutanga dzemafuta ekuzora dzinosangana zvakananga neiyo compressed refrigerant, tichifunga nezvekudyidzana pakati pemafuta ekuzora uye refrigerant.Centrifugal oiri inongoshandiswa kuzora iyo rotor inotakura.Inogonawo kusarudzwa maererano nemutoro uye nekukurumidza.
·Sarudza mafuta ekuzora maererano nemhando yefiriji: mafuta ekuzora akabatana zvakananga nefiriji anofanira kufunga nezvekubatana pakati pezviviri.Semuyenzaniso, firiji yakadai sefreon inogona kuparara mumafuta emaminerari, saka giredhi yeviscosity yemafuta akasarudzwa. mafuta anofanirwa kunge ari giredhi rimwe chete rakakwirira kupfuura refiriji isinganyungudike, kuitira kudzivirira mafuta ekuzora kuti asakwanise kuvimbiswa mushure mekucheneswa. Pamusoro pezvo, zvinofanirwa kucherechedzwa kuti mafuta mashoma ekuzora akasanganiswa nefiriji achakanganisa basa refiriji system.The flocculation point yefiriji muchina mafuta indekisi yemhando yekutarisa kana mafuta ekuzora akasanganiswa nefiriji anogona kukonzera wax crystal uye kuvhara firiji system.
Sarudza mafuta ekuzora zvichienderana nekupisa kwekushisa kwefiriji: kazhinji kutaura, refrigerant evaporator ine tembiricha yekufefetera inofanirwa kusarudza mafuta efiriji ane nzvimbo yakaderera yekutonhora, kuitira kudzivirira mafuta ekuzora anotakurwa nefiriji kuenda kune firiji system kubva mukunyungudika pamhepo. vharafu uye evaporator, inokanganisa kushanda kwefiriji.
Nzvimbo yechando yemafuta ekuzora anoshandiswa muammonia refrigerant cooler inofanira kunge yakaderera pane tembiricha yekubuda.
Ikoko freon inoshandiswa sefiriji, nzvimbo yechando yemafuta ekuzora inogona kunge yakakwira zvishoma pane tembiricha yekubuda.
·Sarudza mafuta ekuzora zvinoenderana nemamiriro ekushanda efiriza.
HERO-TECH inoshandisa yakakwira-kirasi chetefiriji mafuta.Zvese zvikamu zvechiller zvedu ndezvemhando yepamusoro, zvakafanana zvinoenda kune firiji mafuta.Tinoda mafuta efiriji akanaka kuti titsigire kugadzikana uye kushanda kwenguva refu kwemuchina.
Saka, vimba HERO-TECH, vimba nenyanzvi yebasa refiriji.
