Suzhou how to do the water in the oil

Date of release:2017-12-09 Author: Click:

As the economy continues to evolve, the actual demand for lubricants in the industry continues to increase, and their performance is very prominent, therefore, very popular. If it is because of some external factors, resulting in changes in the quality, it really worth the candle. Well, in our life, if we do not care, there is water in the lubricating oil, what should we do? The following by industry experts for a detailed introduction.

There are three forms of moisture contamination in the lubrication system: dissolved water, emulsified water, free water. Dissolved water refers to the water dissolved in the oil, the naked eye can not see. When the oil content of Suzhou lubricating oil is higher than the limit of oil solubility, the oil will be saturated, tiny water droplets will be suspended in the oil to form emulsified water. From the exterior view, the transparency of the oil is reduced, the turbidity is whitish and the oil emulsifies. Free water refers to the water after stratification, because the oil is usually lighter than water, free water in the lower.

There are five common ways to determine the water content in a lubricating oil, which includes both methods that can be tested on site, as well as laboratory tests.

First, heating method:

This method can make the basic judgments, the operation is simple, the use of a piece of iron, heated to about 130 ℃ on the fire, drop a drop of oil on the iron, oil experts suggest that if there is water bubbles will be observed because Oil in the water evaporation caused by heat bubbles, the larger the bubble, the greater the number, indicating more water content. If you see the bubble can hear crackling crackle, indicating a relatively large amount of water, may have reached 2000ppm above, note that the heating method is only applicable to the determination of emulsified water and free water.

Second, calcium hydride reagent test:

Lube oil manufacturers say that the use of calcium hydride pressure detection device is also a simple method of on-site testing, the principle is that the reaction of moisture and calcium hydride will release hydrogen, causing the pressure in a sealed container changes. The change in pressure can calculate how much water reacts with calcium hydride, which is less costly.

Third, the relative humidity sensor test:

Humidity sensor is also a kind of on-the-spot test, through a layer of capacitance film, sensing the dispersion of humidity content on the film, the advantage is low price, can be installed on important equipment, long-term, real-time monitoring of equipment,

Water in the oil and equipment suffer, so the earlier the better, the early monitoring of the water and the root cause of the treatment as soon as possible can prevent the physical and chemical properties of the lubricating oil from being destroyed, if it is found that the oil enters the water.

Fourth, the natural settlement method:

Can only get rid of free water, oil lighter than water, by gravity, water subsidence in the tank after the water can be let down, but not for emulsified water and dissolved water.
