Chekutanga, basa remafuta ekuzora:
1) Chisimbiso chinoshanduka chinogadzirwa pakati pesikuruu, imba yekudzvanya uye masikuruu echirume neechikadzi kuderedza kubuda kwerefrigerant kubva kudivi rekudzvanya kwepamusoro kuenda kudivi rekudzvanya kwakaderera panguva yekudzvanya.
2) Kuti itonhorese firiji yakamanikidzwa, mafuta anopinzwa mucompressor kuti atore kupisa kunogadzirwa negasi refiriji panguva yekumanikidzwa uye kuderedza tembiricha yekubuda kwemhepo.
3) Firimu remafuta rinoumbwa pakati pebearing nescrew kuti ritsigire rotor uye riite mafuta.
4) Inotumira simba rekumanikidza kwakasiyana-siyana, inotyaira sisitimu yekugadzirisa kugona, uye inogadzirisa nzvimbo yeslider yekugadzirisa kugona kuburikidza nekushanda kwevharuvhu yesolenoid inorodha uye inoburitsa yecompressor kuti ione kutonga kwekugadzirisa kugona kwecompressor.
5) Deredza ruzha rwekumhanya
ratidza:
Mafuta ekuzora ari mukati mecompressor ndiwo musimboti wekuchengetedza mashandiro akajairika ecompressor. Matambudziko akajairika emafuta ekuzora ndeaya:
1) Zvinhu zvekunze zvinosanganiswa, zvichikonzera kusvibiswa kwemafuta ekuzora uye zvinovhara firita yemafuta.
2) Kupisa kwakanyanya kunokonzera kuora kwemafuta ekuzora uye kurasikirwa nebasa rekuzora.
3) Kusvibiswa kwemvura, acidization uye kuora kwemota musystem.
2. Kuongorora nekutsiva mafuta efriji yecompressor:
Kune vagadziri vemasystem, kutenderera kwekuona nekutsiva oiri yekutonhodza yecompressor kune chekuita nekudzora maitiro ekugadzirwa kwayo. Kana kuchena kwe evaporator, condenser uye pombi yesystem zvikadzorwa zvakanaka, kusvibiswa kunopinda mucompressor kuchava kushoma, uye nguva yekuongorora nekugadzirisa inogona kuwedzerwa zvishoma.
Zviratidzo zvikuru zvekutarisa:
1) PH value index: Kuwanda kweacid mumafuta ekuzora kuchakanganisa hupenyu hwemota yecompressor, saka zvakakosha kugara uchitarisa kana acidity yemafuta ekuzora inokodzera. Kazhinji, acidity yemafuta ekuzora yakaderera pane PH6 uye inoda kutsiviwa. Kana acidity isingakwanise kuongororwa, filter dryer yesystem inofanira kutsiviwa nguva nenguva kuti kuoma kwesystem kurambe kuri mumamiriro akajairika.
2) Nhamba yedhigirii rekusvibiswa: Kana kusvibiswa kuri mu 100ml yemafuta ekufiriji kwakapfuura 5mg, zvinokurudzirwa kutsiva mafuta ekufiriji.
3) Mvura: inopfuura 100ppm, mafuta emufiriji anofanira kutsiviwa.
Kutsiva kutenderera:
Kazhinji, mafuta ekuzora anofanira kuongororwa kana kutsiviwa maawa gumi ega ega ekushanda, uye mushure mekuvhiyiwa kwekutanga, zvinokurudzirwa kutsiva mafuta ekuzora uye kuchenesa firita yemafuta maawa maviri nemazana mashanu ega ega. Zvasara zvinokonzerwa nekuungana kwesystem zvichaungana mucompressor mushure mekushanda chaiko. Saka, mafuta ekuzora anofanira kutsiviwa maawa maviri nemazana mashanu ega ega (kana mwedzi mitatu), uye nguva nenguva zvichienderana nekuchena kwesystem. Kana kuchena kwesystem kwakanaka, kunogona kutsiviwa maawa gumi ega ega (kana gore rega rega).
Kana tembiricha yekubuda kwemuchina wecompressor ikaramba iri patembiricha yakakwira kwenguva yakareba, kuora kwemafuta ekuzora kuchakurumidza kukura, uye hunhu hwemakemikari emafuta ekuzora hunofanira kuongororwa nguva dzose (mwedzi miviri yega yega), uye kutsiviwa kana isina kukodzera. Kana kuongororwa nguva dzose kusingagoneke, kunogona kuitwa zvichienderana netafura inotevera yekurudziro.
3. Nzira yekushandisa yekutsiva oiri mufiriji:
1) Kutsiva oiri yekutonhodza pasina kucheneswa mukati:
Compressor inoita chiito chekupomba kuti idzorere refrigerant yesystem kudivi recondenser (cherechedza kuti kumanikidzwa kushoma kwekusveta kwekushanda kwekupomba hakusi pasi pe 0.5Kg/cm2G), bvisa refrigerant mucompressor, chengeta kumanikidzwa kwemukati sesimba remagetsi, woisa refrigerant. Mafuta anodururwa kubva muvharuvhu yekona yekudhonza mafuta yecompressor.
2) Tsiva oiri yefiriji wochenesa mukati:
Kubuda kwemafuta mufiriji kwacho kwakafanana nekutsanangurwa pamusoro apa. Mushure mekunge mafuta efriji abuda akachena uye kumanikidzwa mukati nekunze kwecompressor kwaenzana, sunungura mabhoti eflange neAllen wrench, uye bvisa joint yemafuta filter neflange yegomba rekuchenesa (kana oil level switch flange). Mushure mekuchenesa, bvisai tsvina mutangi remafuta recompressor, tarisai kana mesh yemafuta filter yakakuvara, uye bvisai tsvina, tsvina, nezvimwewo zviri pairi, kana kutsiva oil filter neimwe itsva. Filter interface nati inofanira kusimbiswa uye kuvharwa kudzivirira kubuda kwemukati; gasket yemukati yejoint yemafuta filter inofanira kutsiviwa neimwe itsva kudzivirira kubuda kwemukati; mamwe magasket eflange anokurudzirwawo kuti agadziriswe.
Zvinyorwa zvina:
1. Mafuta emufiriji akasiyana haafanirwe kusanganiswa, kunyanya mafuta emineral uye mafuta eester ekugadzira haafanirwe kusanganiswa.
2. Kana ukatsiva oiri yefiriji yeimwe mhando, chenjerera kubvisa oiri yefiriji yekutanga yasara musystem.
3. Mamwe mafuta ane hunhu hwe hygroscopic, saka usaise mafuta ari mufiriji mumhepo kwenguva yakareba. Paunenge uchiisa, deredza nguva yekuaisa uye ita basa rakanaka rekupukuta mafuta.
4. Kana mota yecompressor yatsva musystem, kutarisisa kwakakosha kunofanirwa kupihwa pakubvisa zvinhu zvine acidic zvasara musystem pakutsiva muchina mutsva, uye acidity yemafuta ekufiriji inofanira kuongororwa mushure memaawa makumi manomwe nemaviri ekuvhurwa nekushanda. Zvinokurudzirwa kutsiva mafuta ekufiriji nekuomesa, kuderedza mukana wekuora kweacid. Mushure mekushanda kwemwedzi ungangoita mumwe chete, tarisa kana kutsiva mafuta ekufiriji zvakare.
5. Kana paine tsaona yekupinda kwemvura musystem, kungwarira kunofanirwa kupihwa pakubviswa kwemvura. Pamusoro pekutsiva oiri yekufiriji, kutarisisa kunofanirwa kupihwa pakuona acidity yemafuta, uye kutsiva oiri itsva nefirita yekuomesa nenguva.
