1. what is viscosity. When the liquid moves by external force, the nature of the internal friction between the liquid molecules is called viscosity. In physics, viscosity is explained by the interaction force between fluids. Assuming that the liquid is considered to be a permutation of many layers, when the external force moves and moves each other, a layer of liquid flows along another layer of liquid and has a shear action between the liquid layers. This action is the internal friction of the liquid, and a shear force is produced for the slower liquid layer. At the same time, at the same time, the flow of the slow liquid layer produces the reverse shear force acting on the liquid layer which is faster and decelerates. The force of the shear force showing the impedance is called the internal friction force. The nature of the interaction inside the liquid is called the viscosity of the liquid. After a long period of use of the new hydraulic oil, the viscosity of the oil will become smaller. It is not easy to form a protective film in the equipment lubrication system and increase the wear angle of the equipment.
(1) power blight. Also called absolute viscosity. That is, when the area of lcm2 is two and the distance between the two layers of LCM is relative motion. The internal friction produced, called dynamic viscosity, is usually expressed as a symbol. When the internal friction force is equal to 1dyn at T C, the viscosity of the liquid is unit dynamic viscosity and the unit is g/ (cm.s) when the internal friction force is equal to the lcm/s2 acceleration of the object of 1G mass. The IP indicates that the interval 1cm layer is in the lcm'surface. The shear force of the product is ldyn, so the one percent berth is called crest. The dynamic viscosity is applied to the scientific research work.
(2) motion viscosity. Also known as dynamic viscosity or internal friction coefficient. It is the ratio of the dynamic viscosity of the liquid to the liquid density p at the same temperature. It is indicated by the symbol V, that is, when the temperature is t degrees, the kinematic viscosity is expressed by vt. Because the unit of dynamic viscosity is g/ (cm.s), the unit of density is g/cm', so the unit of kinematic viscosity is the unit of kinematic viscosity called "support" or "the" symbol is "St". The 1 support is equal to lcm's, and the one percent of the bracket is cSt. That is, 1 degrees of 1mm. is the most commonly used viscosity in the world.
(3) conditional viscosity. Refers to the viscosity measured by different viscometer. There are three kinds of conditional viscosity commonly used in the world. 1) a ratio of the number of seconds required for the flow of 200ml from the een's viscometer at a specified temperature (such as 50 C, 80 c) at the specified temperature (such as 50 and 80 c), and the ratio of the number of seconds (or water value) required for the flow of water at the temperature of the androgynous water at the specified temperature. It is represented by the symbol "E". At temperature tC, the viscosity of een is expressed in E. The unit is "degree".
2) the viscosity of the saibor, that is, the viscosity of the saiter. The number of seconds needed to discharge 60ml from the Sai's viscometer at a specified temperature (such as 100F, 210F) is based on "s". The viscosity is divided into the general viscosity of the Sai and the viscosity of the sirril heavy oil (or sirris flo viscosity), that is, the viscosity of redwood, which is a certain amount of sample. At the specified temperature, the number of seconds required to outflow the 50ml from the Rex viscometer is used as a unit of "s". The viscosity of Lei is divided into Lei's 1 (expressed in R) and Lei's 2 (expressed in R2) two.
The main factors affecting the viscosity of oil products. The new hydraulic oil is related to the fraction of the base oil. In general, the heavier the distillate from the same petroleum, the greater the viscosity. Conversely, the lower the fraction of the cut, the smaller the viscosity. That is to say, the viscosity of the same petroleum fraction increases with the increase of boiling point and decreases with the decrease of boiling point. It is related to the chemical composition of oil. A large number of experiments show that in the same fraction, the viscosity of alkanes is the smallest, the viscosity of ISO paraffins is slightly higher than that of n-alkanes, and the viscosity of cyclic hydrocarbons is much larger than that of alkanes, and the viscosity of glial and non hydrocarbon is the greatest. In the annular channel, the viscosity increases with the increase of the number of rings. The viscosity of oil has a great relationship with the temperature. The viscosity decreases with the increase of temperature and increases with the decrease of temperature. But this change is not linear, sometimes more stable. In addition, this change is related to the composition and refining process of crude oil. The pressure and velocity of liquid acting on the liquid also affect viscosity. The change of the viscosity of the waste liquid pressure is mainly with the operating time of the equipment and the operating environment of the equipment. The waste liquid in the steel industry is mainly containing more impurities, and the oil is easy to carbonization at high temperature. The main waste water in cement industry is water content. The filtration of waste liquid oil mainly adopts the imported vacuum dewatering and regeneration device of hydraulic oil filter. In vacuum, the viscosity and value of the oil and the impurities in the oil molecules can be diluted to meet the standard of use and save the cost.
