A, basa remafuta ekuzora:
1) mu screw ne compression chamber uye pakati pe yin ne yang screw kuti pave dynamic seal, deredza refrigerant mu compression process kubva ku high pressure side kuenda ku low pressure side yekubuda kwemvura.
2) kutonhodza refrigerant iri kumanikidzwa, mafuta anopfapfaidzwa mucompressor, achitora kupisa kunogadzirwa negasi rerefrigerant panguva yekumanikidzwa, zvichideredza tembiricha yekubuda kwemhepo.
3) Mubheya uye sikuruu pakati pekuumbwa kwefirimu remafuta kutsigira rotor, uye kuita basa rekunyorovesa.
4) Chinja simba rekumanikidza rakasiyana, fambisa sisitimu yekugadzirisa kugona, nekuita kwekuburitsa nekuwedzera solenoid valve yecompressor, uchigadzirisa nzvimbo yecapacity adjustment slider, kuti uwane simba rekugadzirisa kugona kwecompressor.
5) Deredza ruzha rwekushanda
Tsananguro:
Mafuta emukati mecompressor ndiwo kiyi yekuchengetedza mashandiro akajairika ecompressor, matambudziko ese ekuzora ndeaya:
1) zvinhu zvekunze zvakasanganiswa, zvichikonzera kusvibiswa kwemafuta, zvichivhara firita yemafuta.
2) Kupisa kwakanyanya kunoita kuti mafuta apise uye asashande zvakanaka pakuzora mafuta.
3) Kusvibiswa kwemvura yemuchina, acidization, kuora kwemota.
Chechipiri, kuyedzwa nekutsiviwa kwemafuta efriji yecompressor:
Kune mugadziri wesystem, kuyedzwa kwecompressor refrigeration oil uye kutsiva oiri kunoenderana nekudzora maitiro ekugadzirwa kwayo. Kana evaporator necondenser uye system pombi yekucheneswa kwesystem zvakanaka, saka kusvibiswa kushoma mucompressor, kutenderera kwekuona nekugadzirisa kunogona kutora nguva yakareba.
Zviratidzo zvikuru zvekutarisa:
1) PH value index: acidization yemafuta ekuzora ichakanganisa zvakananga hupenyu hwemota yecompressor, saka acidity yemafuta ekuzora inofanira kuongororwa nguva nenguva kuti ionekwe kana yakakodzera. Acid yakawanda yemafuta ari pasi pePH6 inodiwa kuti itsiviwe. Kana acidity isingakwanise kuongororwa, filter dryer yesystem inofanira kutsiviwa nguva nenguva kuti system irambe yakaoma.
2) Nhamba yekusvibiswa: Kana tsvina iri mu 100ml yemafuta ekutonhodza ikadarika 5mg, zvinokurudzirwa kutsiva mafuta ekutonhodza.
3) Huremu hwemvura: Kana ichipfuura 100ppm, zvinodikanwa kutsiva oiri yekutonhodza.
Kutenderera kwekutsiva:
Kazhinji maawa gumi ega ega ekushanda anofanira kutarisa kana kutsiva mafuta acho, uye mushure mekushanda kwekutanga, maawa mazana maviri nemazana mashanu (2500) anokurudzirwa kutsiva mafuta acho nekuchenesa firita yemafuta. Nekuti zvasara zvemusanganiswa wesystem zvichaunganidzwa mucompressor mushure mekushanda kwepamutemo. Saka, mafuta ekuzora anofanira kuchinjwa kamwe chete mumaawa mazana maviri nemazana mashanu (kana mwedzi mitatu), uye wobva wachinja nguva nenguva zvichienderana nekuchena kwesystem, kana kuchena kwesystem kwakanaka, kunogona kuchinjwa kamwe chete mumaawa chiuru (kana gore rega rega).
Kana tembiricha yekuburitsa compressor ikaramba ichigadziriswa kwenguva refu mumamiriro ekupisa kwakanyanya, mafuta anoora nekukurumidza, anofanira kunge ari nguva dzose (mwedzi miviri yega yega) achitarisa hunhu hwemakemikari emafuta, asi haana kutsiviwa. Kana usingakwanise kutarisa nguva dzose, unogona kutevedzera tafura inotevera yemazano.
Nhatu, nzira yekushanda yekutsiva mafuta mufiriji:
1) Kutsiva oiri yemufiriji pasina kucheneswa mukati:
Compressor inoita chiito chekupomba kuti idzorere refrigerant yesystem kudivi recondenser (cherechedza kuti kumanikidzwa kushoma kwekupomba hakusi pasi pe0.5Kg/cm2G), bvisa refrigerant kubva mucompressor, chengeta kumanikidzwa kwemukati sesimba remagetsi, uye buritsa mafuta erefrigerant kubva muvharuvhu yekuburitsa mafuta yecompressor.
2) Chinja mafuta emufiriji wochenesa mukati:
Bvisa mafuta sezvakatsanangurwa pamusoro apa, mushure mekunge mafuta emufiriji abviswa uye kumanikidzwa mukati nekunze kwecompressor kwaenzana, shandisa chipanera chehexagonal kusunungura mabhoti eflange, bvisa chinongedzo chefiriji yemafuta uye bvisa flange yegomba (kana flange yekuchinja mafuta), bvisa tsvina mutangi remafuta ecompressor, uye tarisa kana mesh yegomba refiriji yemafuta yatyoka, uye bvisa tsvina netsvina pairi, kana kutsiva firiji yemafuta neimwe itsva, cherechedza kuti Pakutsiva firiji itsva yeinterface nati inofanira kukweshwa zvakasimba uye kuvharwa zvakanaka kudzivirira kubuda kwemukati; liner iri mukati mejoinhi yefiriji yemafuta inofanira kutsiviwa neimwe itsva kudzivirira kubuda kwemukati; imwe flange liner inokurudzirwawo kuti ivandudzwe.
IV. Zvinyorwa:
1. Mafuta emufiriji akasiyana haafanirwe kusanganiswa, kunyanya mafuta emineral uye mafuta eester ekugadzira haafanirwe kusanganiswa.
2. Kana uchitsiva mafuta emufiriji akasiyana-siyana, nyatsoteerera mafuta emufiriji ekutanga asara musystem kuti asaburitswe.
3. Mamwe mafuta haaonekwe zvakanaka, saka usaisa mafuta mumhepo kwenguva yakareba. Regedza nguva yekuiswa mumhepo zvakanyanya sezvinobvira uye bvisa mafuta akawanda panguva yekuisa.
4. Kana sisitimu yacho iine kutadza kupiswa nemota yecompressor, nyatso tarisa kubvisa acid yasara kubva musisitimu iyi paunotsiva muchina mutsva, uye tarisa acidity yemafuta ekufiriji mushure memaawa makumi manomwe nemaviri ekushanda, zvinokurudzirwa kutsiva mafuta ekufiriji nefiriji yekuomesa kuti uderedze mukana wekuora kweacid. Mushure meizvozvo, edza kana kutsiva mafuta ekufiriji zvakare mushure memwedzi mumwe chete wekushanda.
5. Kana sisitimu yacho yapinda mvura netsaona, nyatso cherechedza kubvisa mvura zvakanaka, uye pamusoro pekutsiva mafuta emufiriji, nyatso cherechedza kuti uone acidity yemafuta uye tsiva mafuta matsva nefirita nekufamba kwenguva.
