Ndeipi density yepeturu?

Mamiriro ezvinhu ayo density yepeturu inotarwa

Iko hakuna hukama hwakananga pakati pemhando yepeturu (izvi zvinoshandawo kune density yemafuta edhiziri kana kuwanda kweparafini), nekuti zviyero zvese zvinofanirwa kuitika pane imwe tembiricha. Ikozvino GOST R 32513-2013 inogadzirisa tembiricha yakadaro pa15ºС, nepo yekare chiyero - GOST 305-82 - ichifunga tembiricha iyi kuva 20ºС. Naizvozvo, kana uchitenga peturu, hazvisi zvakanyanyisa kubvunza kuti ndeipi chiyero chakatemerwa density maererano. Mhedzisiro, sekunge ese mahydrocarbons, achasiyana zvakanyanya. Iyo chaiyo giravhiti yepeturu yakaenzana nekukosha kwehuwandu hwayo, apo iyo yekupedzisira inoyerwa mukg / l.

Gasoline density mu kg/m³ kazhinji inoshanda sechigumbuso muhukama pakati pemugadziri nemutengi wemafuta. Dambudziko nderekuti nekudzikira kwehuwandu, huwandu hwepeturu mubatch hunodzikira, nepo vhoriyamu yaro inoramba iri padanho rimwe chete. Musiyano unogona kusvika mazana nezviuru zvemarita, asi kana uchitenga peturu pakutengesa, izvi hazvisi kunyanya kunetsa.

Ne density, iwe unogona zvakare kuseta rudzi rweoiri kubva kwaigadzirwa peturu. Kune mafuta anorema, ane sarufa yakawanda, kuwanda kwakakwira, kunyangwe kuita kwakawanda kwepeturu hakukanganisike zvakanyanya nekuumbwa kwemafuta ekutanga, ingori yakakodzera tekinoroji ye distillation inoshandiswa.

Kuwanda kwepeturu kunoyerwa sei?

Chero peturu musanganiswa wemvura wemahydrocarbons unowanikwa semhedzisiro yefractional distillation yemafuta. Aya ma hydrocarbons anogona kuiswa muzvikamu zvinonhuhwirira, zvine zvindori zvekabhoni maatomu, uye aliphatic makomisheni, ayo anongove akatwasuka kabhoni cheni. Naizvozvo, peturu ikirasi yemakomponi, kwete musanganiswa chaiwo, saka kuumbwa kwayo kunogona kusiyana zvakanyanya.

Nzira iri nyore yekuona density kumba ndeiyi inotevera:

1. Chero mudziyo wapedza kudzidza unosarudzwa uye unoyerwa.
2. Mhedzisiro yakanyorwa.
3. Chigaba chacho chinozadzwa ne100 ml yepeturu uye inoyerwawo.
4. Huremu hwemudziyo usina chinhu hunobviswa kubva pahuremu hwegaba rakazadzwa.
5. Mhedzisiro yacho inokamurwa nehuwandu hwepeturu yaive mutangi. Izvi zvichava density yemafuta.

Kana uine hydrometer, unogona kutora kuyerwa neimwe nzira. A hydrometer chishandiso chinoshandisa iyo Archimedes musimboti wekuyera chaiyo giravhiti. Musimboti uyu unoti chinhu chinoyangarara mumvura chinobvisa huwandu hwemvura yakaenzana nehuremu hwechinhu. Zvinoenderana nezviratidzo zveiyo hydrometer chiyero, iyo inodiwa parameter inoiswa.

Kuyera kutevedzana kunotevera:

1. Zadza mudziyo wakajeka uye unyatsoisa iyo hydrometer mupeturu.
2. Tenderedza hydrometer kudzinga chero mabhuru emhepo uye tendera chiridzwa kuti chigadzikane pamusoro pepeturu. Zvakakosha kubvisa mabhuru emhepo nokuti achawedzera buoyancy ye hydrometer.
3. Isa iyo hydrometer kuitira kuti peturu iri pamusoro peziso.
4. Nyora pasi kukosha kwechiyero chinoenderana nepamusoro pezinga repeturu. Panguva imwecheteyo, tembiricha iyo kuyerwa kwakaitika inonyorwa zvakare.

Kazhinji peturu ine density muhuwandu hwe700 ... 780 kg / m³, zvichienderana nekugadzirwa kwayo chaiko. Mishonga inonhuhwirira haina kuomesesa pane aliphatic komisheni, saka kukosha kwakayerwa kunogona kuratidza chikamu chehukama hwemakomponi aya mupeturu.

Kakawanda kacho, pycnometers anoshandiswa kuona kuwanda kwepeturu (ona GOST 3900-85), sezvo zvishandiso izvi zvezvinwiwa zvinoputika uye zvakaderera-viscosity hazvina kusiyana mukugadzikana kwekuverenga kwavo.

Density yepeturu AI-92

Chiyero chinotaridza kuti density yeAI-92 unleaded peturu inofanirwa kunge iri mukati me760 ± 10 kg / m.³. Kuyera kunofanira kuitwa patembiricha ye15^ºC.

Density yepeturu AI-95

Iyo yakajairwa kukosha kwe density yeAI-95 peturu, iyo yakayerwa patembiricha ye15.^ºC, yakaenzana ne750±5 kg/m³.

Density yepeturu AI-100

Chiratidzo chepeturu iyi - Lukoil Ecto 100 - inoisa iyo yakajairika density chiratidzo, kg / m.³, mukati me725…750 (zvakare pa15^ºNE).
