Lubricating oil ( Fat) The density of the relevant knowledge in jiaxing bearing group

There is rotational, have HRB bearing ( ) Lubricating oil ( Fat) The density of the relevant knowledge in jiaxing bearing group. Jiaxing bearing group sales co. , LTD. ( The company) Is in jiaxing bearing group set up by the spot sales window, specializing in HRB brand bearings, existing stocks of 50 million yuan, covers the whole bearing, have very strong cash supply ability. Lubricating oil ( Fat) Density: the density is the most simple petroleum and its products, the most commonly used physical properties index, it refers to the prescribed temperature quality content per unit volume, unit is: kg/m3 because under different temperature, the density changes, high temperature measured density measured density is smaller than the low temperature. For comparison, the density of general oil density is used to a specified temperature, under. Our country GB regulation, the standard temperature ( 20℃） The density of standard, the density of g/cm3. Density is important in the production greatly, metering, refinery process design are used in products. To some extent, can be judged in terms of product quality, also used in the conversion number density, the measurement of acceptance of delivery. Simple judgment oil properties, according to the density is roughly estimated crude oil types, such as alkane containing more crude oil density is often relatively low density of crude oil containing cycloparafin hydrocarbon and aromatic hydrocarbons. The more sulfur, oxygen, nitrogen compounds and colloid and asphalt, the more the higher density of crude oil. The density can be determined primarily oil varieties: gasoline P = 0. 7 - 0. 76 g/cm3 aviation kerosene 0. 77 - 0. 84 g/cm3 lubricating oil 0. 87 - 0. 89 g/cm3 density can approximate evaluation of oil quality and chemical composition change, especially in the process of shipping, if found some oil density increase or decrease obviously, can determine whether mixed with heavy oil or light oil. 24-hour customer service hotline: if you are more interested in jiaxing bearing manufacturer introduces industry information or have any questions, please click on contact us page on the right side of the online customer service, or call:, you close the way of jiaxing bearing purchasing advisors. - - - - - - Editor: HRB bearing company sourcing consultant LTD.
