Application of Vacuum Dehydration Oil Purification System

July 19,2017.

Most of Vacuum Oil Purification System use vacuum tank to dehydration, the principle is to be treated into the vacuum tank, oil volatile gases (including water vapor) volatile to the vacuum tank, degassed after treatment of oil In the role of gravity gathered to the bottom of the vacuum tank. Vacuum Dehydration Oil Purification System is generally continuous operation, so with a vacuum pump from the top of the vacuum tank continuously withdraw the gas, pump from the bottom of the vacuum tank out of degassing treatment of oil. The higher the vacuum in the vacuum tank, the faster the degassing process, the better the effect.

Vacuum Oil Purification System remove free water, dissolved water, so the oil can be reduced to a low level of water, the actual can reach 10mg / L or so. In general, the oil system can control the oil content of 80mg / L can be.

Vacuum Oil Dehydration is the only technology that can make a small amount of water leakage in the lubricating oil system.


Technical advantages of Vacuum Dehydration Oil Purification System

A. In theory, the higher the degree of vacuum, the faster the dehydration rate, but the high vacuum operation, if the oil into the water suddenly become larger, vacuum tank will produce a lot of foam, it is easy from the top of the vacuum tank through the vacuum pipe ran into the vacuum pump , Caused by running oil accident, but also easy to make the vacuum pump damage. In order to avoid running oil phenomenon, the general vacuum oil dehydration are equipped with automatic control device, when the bubble and more to the vacuum tank to release the air. Since this reduces the operating vacuum, the actual dewatering speed is relatively slow.

B. In the past, Vacuum Dehydration Oil Purification System use oil rotary vane vacuum pumps. When the percentage of the gas vapor in the sample is high, the water vapor is precipitated inside the vacuum pump and mixed with the vacuum pump oil to cause the vacuum pump oil to emulsify. Excessive emulsification of the oil vapor pressure is high, the vacuum pump is no longer able to extract the gas from the vacuum tank, oil dehydration rate is very low. Serious may be from the vacuum pump outlet oil and water mixture, but also serious damage to the vacuum pump.

C. In order to compensate for the above problems caused by the slow speed of dehydration, the previous vacuum oil purification system are equipped with high-power heater, the oil temperature rose to 55 or more. But the disadvantage is high energy consumption, and high-power heater due to heat power, long-term reliability of the poor, there are security risks.


Application of Vacuum Dehydration Oil Purification System in Lube Oil

Lube Oil Purification System uses a new process to solve the problem of lubricating oil under high vacuum conditions, it can be in high vacuum conditions, the use of rapid flashing process rapid dehydration; oil-free vacuum pump to solve the vacuum pump oil water, maintenance cycle is short; high vacuum operation without heating, running low energy consumption, high reliability.

As the vacuum oil purification system does not need to change according to the change in water content at any time to adjust the operating parameters, in general use only need to start, stop button, the operation is very convenient.


Application of Vacuum Dehydration Oil Purification System in Transformer Oil

Double Stages Vacuum Dehydration Oil Purification System can do continuous dehydration operation, after a period of time, the oil content of water can reach less than 100mg / L GB requirements.

After the water content in the oil reaches the standard, it will significantly improve the operational safety of the oil system and reduce the wear of the moving parts. At the same time, the corrosion products in the oil will be significantly reduced, the particulate matter content will be significantly reduced, the filter life will be doubled. As the Double stages Vacuum Dehydration Oil Purification System supports the filtration diameter of 250mm, the filter area is more than 3 times the general filter, so the filter will have a longer life in the oil system with water qualified, it is estimated that the filter replacement cycle can be achieved Six months. In this way, the maintenance workload of the oil system will be significantly reduced, operating costs will be significantly reduced.
