Ko synthetic uye semi-synthetic injini oiri inogona kusanganiswa here? ZIK, Mobile, Castrol, nezvimwe.
Vatyairi vazhinji vanowanzoshamisika kana ichibvumidzwa kusanganisa mafuta ekugadzira mota uye semi-synthetics? Ngatiedzei kuzvinzwisisa.
Chii chinonzi synthetic mota oiri?
Synthetic mota oiri (synthetics) inogadzirirwa murabhoritari, ichigadzira akawanda mafomula. Mafuta akadaro anogona kuderedza kupokana pakati pezvikamu zveinjini. Izvi zvinowedzera zvakanyanya hupenyu hweinjini. Panguva imwecheteyo, kushandiswa kwemafuta kunoderedzwa.
Injini yakadaro inogona kushandiswa chero ipi zvayo yekushisa, mumamiriro ezvinhu akanyanyisa. Chii chinosiyanisa mafuta ekugadzira kubva kumafuta emaminerari ndeye inodzorwa kemikari maitiro.
Nheyo yemafuta chero ipi zvayo mafuta, ayo anogadziriswa pachiyero che molecular kuti awane mineral oil. Inosanganiswa nekuwedzera, kuburikidza nekushandiswa kwavanopa mafuta anokosha maitiro.
Muchokwadi, synthetics inovandudzwa mineral oiri.
Mamiriro ekugadzira akakosha anokonzera mutengo wakakwira. Chete mhando dzemota dzakanakisa dzinozvibvumira kugadzira injini umo zvinokurudzirwa kushandisa mafuta akadaro.
Chimiro chechimiro chemafuta ekugadzira ndiko kugona kuchengetedza zvimiro zvayo nekufamba kwenguva. Zvimwe zvinhu zvinosanganisira:
- high viscosity;
- yakagadzikana thermal oxidation;
- inenge isingaputiki;
- inoshanda zvikuru muchando;
- yakaderedzwa coefficient of friction.
Kuumbwa kwesynthetics kunosanganisira zvinhu zvakadai se esters uye hydrocarbons. Chiratidzo chikuru ndeye viscosity (yakajairika iri muhuwandu hwe120-150).
Chii chinonzi semi-synthetic injini oiri?
Semi-synthetics inowanikwa nekubatanidza mineral uye synthetic mafuta mune imwe chikamu. 70/30 inoonekwa seyakanaka. Semi-synthetic mafuta inosiyana mune viscosity, i.e. kukwanisa kuramba uri pamusoro pezvikamu zvejini, asi pasina kurasikirwa nemvura. Iyo yakakwirira iyo viscosity, iyo yakakura iyo layer yemafuta pane zvikamu.
Semi-synthetic ndiyo yakajairika mhando yemafuta nhasi. Kugadzirwa kwayo hakudi kudhura kwakakwira, uye zvivakwa zvacho zvishoma zvakaderera kune synthetics.
Unogona kusanganisa here?
Vapepeti vevodi.su portal havakurudzire kusanganisa marudzi akasiyana emafuta. Zvakare, uye pamwe zvine njodzi zvakanyanya, kushandura mugadziri. Hazvibviri kufanotaura kuti chii chichaguma kubva pakubatanidzwa kwakadaro. Zvinongova nengozi kuita zviyedzo zvakadaro pasina marabhoritari, zvishandiso uye bvunzo dzakakwana. Sarudzo yakanyanyisa ndeye kushandisa zvigadzirwa zvemhando imwechete. Ipapo pane mukana wekumwe kuenderana. Kazhinji kusanganiswa kunoitika panguva yekuchinja kwemafuta. Iwe haufanirwe kushandura vagadziri, pachave nekukuvadza kwakawanda pane kutsiva mafuta ekugadzira ne semi-synthetics, asi kubva kumugadziri mumwe chete.
Injini yekutsvaira inodiwa riini?
Iwe unofanirwa kuchenesa injini:
- pakutsiva imwe mhando yemafuta neimwe;
- pakuchinja mugadziri wemafuta;
- pakuchinja mafuta parameters (somuenzaniso, viscosity);
- kana ikasangana nemvura yekunze;
- paunenge uchishandisa mafuta asina kunaka.
Nekuda kwekusagadzikana kwemafuta, injini inogona rimwe zuva kungojamba, tisingatauri kurasikirwa kwesimba, kukanganisa mukushanda uye mamwe "mazango".
Asi, hazvisi zvese zviri nyore. Kusanganisa mafuta akasiyana kune mafeni ayo. Kukurudzira kuri nyore. Kana iwe ukawedzera zvishoma zvinyorwa zvekugadzira, hazvizove zvakanyanya kuipa.
Zvimwe zvakadaro, asi mukati memutsara wemugadziri mumwe chete, uyezve kana zvigadzirwa zvaro zvichienderana neAPI uye ACEA zviyero. Mushure mezvose, munhu wose ane zvinyorwa zvake. Chii chichava mhedzisiro - hapana anoziva.
