Lubricating oil ( Fat) The viscosity of the relevant knowledge in jiaxing bearing factory

There is rotational, have HRB bearing ( ) Lubricating oil ( Fat) The viscosity of the relevant knowledge in jiaxing bearing factory in 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. Jiaxing bearing on lubricating oil ( Fat) The viscosity, viscosity is one of the important physical and chemical indicators, lubricating oil for different grade of lubricating oil classification, quality identification, determine the purpose have decisive significance, is also indispensable in the process of design and calculation of the physical constants. Liquid, semiliquid state substances under external force, the flow between the molecules of internal friction, or resistance. We use international standard and kinematic viscosity m2 / s, was used in practical production/s two relations for 1 m2 / s = 106 was/s ( Crude oil) Lubricating oil viscosity with temperature and the degree of change, as the viscosity-temperature property, average temperature, the lower viscosity, lower temperature, the viscosity increases, viscosity ratio refers to the oil temperature prescribed by the two kinematic viscosity under low temperature can be measured by the ratio of kinematic viscosity and higher temperatures. Our country and the international ISO standards, the use of 40 ℃ and 100 ℃, the viscosity index refers to the oil viscosity changes with temperature this feature a prescribed value, high viscosity index, said oil with temperature changes little, through the table can be found. The viscosity of oil production and use of what is the point? ( 1) In engine viscosity increases, will affect the power, the viscosity is too low will cause starting difficulty, reduce oil film support ability. ( 2) Most of the lubricating oil viscosity is according to the division is to choose lubricating oil a basis. ( 3) The viscosity cooling effect is poor. Because of the slow loop and fewer through filter, washing effect is poor. ( 4) Low viscosity of oil, the oil film is easy to broken. ( 5) The sealing effect is bad. ( 6) Increase the lube oil consumption. 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.
