Qhov ntom ntawm kerosene: qhov taw qhia nyob ntawm seb dab tsi thiab nws cuam tshuam dab tsi
Txheem
Qhov ceev ntawm kerosene yog ib qho ntawm ntau yam ntxwv ntawm ib yam khoom uas txiav txim siab nws cov khoom. Ua ntej lub advent ntawm cov cuab yeej tshwj xeeb, qhov parameter no qhia tau hais tias qhov zoo ntawm cov khoom. Kerosene yog siv nyob rau hauv ntau yam kev lag luam thiab tsim nyog rau ntau yam txheej txheem, yog li nws yog ib qho tsim nyog yuav tsum paub raws nraim qhov ceev thiab lwm yam kev ntsuas ntawm cov khoom no, lawv cov kev hloov pauv thiab cov cim ciam teb.
Qhov ceev ntawm kerosene nyob ntawm cov txheej txheem ntawm kev tsim khoom thiab kev hloov kub.
Dab tsi txiav txim siab qhov ntom ntawm kerosene hauv kg / m3
Xav txog qhov ceev ntawm kerosene (kg / m3), siv cov piv txwv ntawm T-1 hom, nws nyob ntawm:
- Fractional muaj pes tsawg leeg.
- txoj kev tsim khoom.
- cia tej yam kev mob.
- kub ntawm qhov teeb meem.
Qhov taw qhia nce nyob rau hauv kev faib ua feem rau cov ntsiab lus ntawm hnyav hydrocarbons nyob rau hauv muaj pes tsawg leeg ntawm cov qauv. Hauv qab no yog cov ntsuas qhov ceev hauv cubic meters ib kilogram nrog gradation ntawm t ° ntawm + 20 ° C rau + 270 ° C.
Rooj: Qhov ceev ntawm kerosene ntawm ntau qhov kub thiab txias nrog lub caij nyoog ntawm 10 ° C
Yuav ua li cas txiav txim siab qhov ntom ntawm kerosene
Txhawm rau txiav txim siab qhov ntom ntawm kerosene, nws yog ib qho tsim nyog yuav tsum siv cov nqi txheeb ze. Ntawm +20 ° C, qhov taw qhia tuaj yeem yog 780 txog 850 kg / m3. Txhawm rau ua cov lej, koj tuaj yeem siv cov qauv:
P20 = PT + Y(T + 20)
Hauv qhov sib npaug no:
- Р - roj ceev ntawm qhov ntsuas t ° (kg / m3).
- Y yog qhov ntsuas kub nruab nrab, kg / m3 (degrees).
- T yog qhov ntsuas kub ntawm qhov ntsuas qhov ntom ntom (° C).
Thaum xaiv cov roj thiab lubricants, nws yog ib qho tsim nyog yuav tsum coj mus rau hauv tus account cov yam ntxwv uas tau muab rau hauv daim ntawv pov thawj zoo.
Thaum T-1 kerosene yog rhuab, nws qhov ceev txo, vim thermal expansion thiab ntim loj hlob tshwm sim vim thermal expansion. Yog li ntawm t ° + 270 ° C, qhov ceev ntawm T-1 hom yuav yog 618 kg / m3.
Dab tsi yog qhov ceev ntawm kerosene ntawm qib sib txawv
Xav txog dab tsi yog qhov ceev ntawm kerosene rau ntau hom. Nrog kev hloov pauv hauv qhov hnyav molecular, qhov sib txawv tuaj yeem qhia tau hauv 5-10%. Nyob rau hauv tus qauv t ° + 20 ° C indications ntawm aviation kerosene nyob rau hauv kg / m3:
- 780 TS-1.
- 766 TS-2.
- 841 TS-6.
- 778 rau RT.
Qhov ceev ntawm lub teeb ci kerosene yog 840 kg / mXNUMX
Yog tias tsim nyog, cov thawj coj ntawm TC "AMOKS" yuav pab koj xam qhov ceev ntawm kerosene hauv cm. Hu rau tus xov tooj +7 (499) 136-98-98. Tom qab tham nrog lub tuam txhab cov kws tshaj lij, koj tuaj yeem kawm paub ntau ntxiv txog cov muaj pes tsawg leeg thiab cov yam ntxwv ntawm cov roj av, cov khoom tseem ceeb ntawm ntau hom thiab lwm yam ntxwv ntawm ntau yam roj.
