What are the factors that affect the demulsification time of turbine oil filter
2018/5/17 Viewers:
Oil and water are insoluble liquids, that is to say, pure oil and water can not form emulsion. There must be substances that can make oil and water form emulsion. This kind of substance is called "surfactant", such as naphthenic acid salt and colloid, which can make oil and water form emulsion. There are three kinds of surfactant - surfactant in oil: (1) low molecules with highly surface active naphthenic soap and low molecular asphaltic acid salts, (2) macromolecules of asphaltene and colloid. (3) inactive solid materials, such as dust, clay and metal scrap.
Therefore, it can be understood that the factors that affect the time of oil demulsification are as follows:
(1) in the process of oil refining, due to the improper depth of refining, the cleaning is not thorough, so that there are residual naphthenic acids and their salts in the oil, which are all surfactant, so the time of oil breaking and emulsifying is increased.
(2) the oil and water are separated from the oil and water, and the emulsification time of the oil is prolonged.
(3) after the continuous oxidation of the oil, naphthenic acid and other organic acids have been formed to increase the content of the naphthenic acid metal saponified substance in the oil, that is, the surfactant is added, and the time of the oil breaking and emulsification is prolonged.
(4) many years of turbine oil, because of its aging degree, oil sludge, sediment and so on, can also promote the emulsification of oil, increase the emulsification time of oil.
The main difference between the turbine oil and other lubricants is the better antioxidation stability and the emulsifying performance. It is mainly used in power plant steam turbines, hydroelectric generators of hydropower stations, and other lubrication situations requiring deep and delicate lubricating oil. Turbine oil is a kind of oil used for steam turbine engines and is suitable for high speed machines. Mechanical lubrication is mainly used for lubrication, cooling, cooling and speed regulation. Turbine is the transliteration of English turbine, which is derived from Latin turbo, which means rotating objects. It is also called a turbine and a turbine. The most important part of turbine is rotating element (rotor or impeller), which is installed on the turbine shaft, and has blades uniformly arranged along the circumference. The energy of the fluid is converted into kinetic energy through the nozzle in the flow, and the fluid impacts the blade when passing through the rotor, and propel the rotor to rotate, thus driving the turbine axis to rotate. The turbine shaft directly or through the transmission mechanism drives other machines to output mechanical work.
