Mafuta arambe achirema

Density - ndiyo uremu fuma, riri chikwata vhoriyamu. The chairema yakayerwa ndiwo arambe achirema (makirogiramu / m³) makirogiramu muzana cubic mita. Kubva makemikari anoumba boka kunoenderana arambe achirema ari mafuta. Zviduku arambe achirema vane Paraffin makabhohaidhiretsi uye yakakura - anonhuhwirira uye naphthenic makabhohaidhiretsi. Fractional Zvinoumba mafuta paupenyu arambe achirema ukoshi. Kunokonzera arambe achirema ari mafuta zvikamu zviduku (mafuta), hwepamusorosoro tembiricha neChikomonisiti rokukwatisa. In tsika nemamiriro dimensionless uwandu. Ichi hama arambe achirema inova nhamba yacho arambe achirema mafuta (mafuta) pane imwe tembiricha kuti arambe achirema mvura, kubatwa zvakaenzana, pane imwe tembiricha zvina Celsius. Pana 4 ° C ari arambe achirema kwemvura 1000 makirogiramu / m³. The hama arambe achirema kunotemwa pa 20 ° C.

The mudziyo, izvo anoyera arambe achirema ramafuta, yainzi hydrometer.

Kuti kuyera arambe achirema nemvura ari kemafuta hydrometer wakaiswa zvokuti aiyangarara pachena ikoko. Pamwero hydrometer nhungirwa arambe achirema tsika. Density inogona rinowanikwa nokushandisa nzira: uremu mu makirogiramu yakakamurwa bhuku iri marita.

Saizvozvowo, nokuziva vhoriyamu uye arambe achirema kusarudza hydrometer hydrometer anonhuwirira, peturu tonnage anogona kuona zviri nyore nokuda vachiwedzera kuti arambe achirema kubudikidza vhoriyamu.

In dzakawanda mafuta arambe achirema (Diesel mafuta, muchina, etc.). Plotnometrov akaita kushandisa hydrometer kana kuti peturu zvigadzirwa. Achienzaniswa chinyakare namano, izvo kuona arambe achirema mafuta (hydrometers) ane mikana yakawanda plotnometr chero. In rakamanikana chaizvo chikuva, uchakwanisa kuyera arambe achirema hydrometer. Kana mvura kuti kuyerwa nerimwe kutenga hydrometer, iwe, kune rumwe rutivi, ungagona kuponesa pamusoro kutenga wemagetsi arambe achirema meter, asi Ukuwo, vachafanira kutenga hydrometers itsva pachinzvimbo yakadonha. Asi kana imi vatenge plotnometr, zvichava nyore nzira kuyera arambe achirema, unogona kurishandisa kwemakore akawanda. Iva nechokwadi kuti kufunga kana kutenga plotnometra kuti chero mudziyo iyi mhando, kunze murabhoritari, unofanira kugara vanopupurirwa kuti kuputika kudzivirirwa, nekuti nokuyerwa rinoitwa mu dzinogona putika munzvimbo.

mafuta arambe achirema chipimo kunokosha kuti kufungidzira mafuta unhu uye kuti huwandu kwayo. Quantification nevazhinji kukarukureta chinhu peturu chigadzirwa nokuyera ayo tembiricha, arambe achirema uye pamwero (kuverenga vhoriyamu).

Misa vakaverenga chaizvo nemhaka parameters izvi zviri chete Kuchinja panguva dzose tembiricha zvichachinja huwandu (padanho) uye mafuta arambe achirema.

Lubrication pazvose zvikamu injini anobvumira mafuta injini. Rinotaura zvikamu unodzivirira firimu, izvo zvinoderedza kukweshera uye vanopfeka, zvichiguma zvakawanda simba hwakatamisirwa nemavhiri. Uyewo kuita tsvina, ngura kuti injini zvikamu uye kunokuvadza deposits. mafuta Engine anogona freshen nechokwadi chokuti combustion mukamuri inobvisa zvakawandisa kupisa nokuisa pasi kusvikira sump.

Mineral mafuta vari nyore anonhuwirira aishandiswa nevanhu kwemakumi emakore. Kubereka pavo wokunatswa kwakafumuka mafuta, ipapo mafuta yakavhenganiswa yokuvirisa siyana izvo kutadzisa paumbwe sludge, zvinodhaka kuti kudzivirira kusakara uye viscosity improvers. Mineral mafuta zvinoitika zvakachipa uye paavhareji.

Murabhoritari kubudisa mafuta chakaita zvokugadzirwa. Ndivo anodhura uye vawane navo kuburikidza kunzwisisa namakemikari pezvakaitwa.

Semisynthetic anonhuwirira muri wemisanganiswa vaviri vokutanga. Ivo avhareji nhamba 20-30% chakaita zvokugadzirwa mafuta uye 70-80% ane zvicherwa.
