Introduction
Cause analysis of oil emulsification:
Oil and water are two immiscible liquids, but under certain conditions, they will form stable or unstable emulsions. In contact with water, the emulsification of oil and the degree of emulsification are mainly determined by the composition of oil, the purity of water and the nature of the components contained, as well as the temperature and vibration of oil-water system.
For example, when there are some surfactants (such as carboxylic acid derivatives) in oil or water, when the temperature and concentration are appropriate, they will associate together to form a dense single molecular layer, which will contain water. A large number of connective bodies are evenly dispersed in the oil to form an oil in water emulsion. It can be seen that the fundamental way to prevent and resist the emulsification of two-phase coexisting system is to control the existence of surfactant in oil-water and destroy the dense monolayer of surfactant.
It is of great significance to prepare industrial gear oil with deep refined base oil to improve the anti emulsification performance of the product oil. However, there are various functional additives (surfactants) in industrial gear oil, which will inevitably affect the separation ability of oil from water. Therefore, the researchers and producers of oil products add a certain proportion of demulsifiers with special characteristics to inhibit this effect, so as to ensure that the oil products have good demulsification resistance.
The effect of controlling the quantity and quality of water mixed in oil on preventing oil emulsification cannot be ignored. In the process of using industrial gear oil, it is absolutely necessary to avoid the mixing of rolling fluid into the oil, because rolling fluid itself is emulsion, which can be considered as the accelerator of oil emulsion. The centralized lubrication system of large gear unit is also an effective way to prevent oil emulsification by prolonging the settling time of oil in use, filtering the circulating oil, centrifugal separation, etc.
To solve the problem of oil emulsification:
After oil emulsification, the special vacuum oil filter produced by our company is mainly used in the fields of petroleum, chemical industry, metallurgy, electric power, etc. it can quickly and effectively remove the free water, emulsion, impurity, gas and other harmful components from the oil, such as turbine oil, turbine oil and lubricating oil with high water content, and can also run online with the lubrication system for a long time, and can also feed the purified oil Line of high-precision, high-purity filtration and purification. Improve the quality of oil and restore its performance. Ensure the normal operation of steam turbine unit, hydraulic system, power system and lubrication system.
Features of special vacuum oil filter for dewatering:
Polymer materials were used to coalesce and demulsify, and micro water molecules in oil were separated.
It can remove 100% free water and 80% dissolved water.
The pressure difference type automatic back washing system is adopted to save the complicated manual removal and washing
Air cooling, water cooling and medium condensation heat exchange device are adopted.
Humanized design, low noise, easy operation, long maintenance interval, low energy consumption, saving operation cost.
