III. Features

1. The advantages of integrated coalescence and vacuum dehydration technology can quickly reduce the water content in the oil to below 50PPM (the coalescence filter system is optional).

The water content in the oil is the main factor that affects the quality of the lubricating oil, and the dehydration efficiency is the first reference index for evaluating the quality of the oil filter. The water in the oil exists in three ways: deposited water, suspended water and dissolved water. The water dissolved in the oil is distributed in the oil in molecular form when it is not saturated. When the water molecules are saturated to a certain extent, the water molecules gather together to form fine particles suspended in the oil. When the water in the oil forms larger particles, it is deposited on the bottom of the container under the action of gravity. The saturated water content in oil is mainly determined by temperature and pressure. The higher the temperature and pressure, the more water the oil can dissolve.

    The advantage of coalescence dehydration is that it can quickly remove the sediment water and suspended water in the oil, but it can do nothing for the dissolved water in the oil; vacuum dehydration can reduce the water content in the oil to below 50PPM, but it is effective in removing the sediment water in the oil. And suspended water efficiency is low. When filtering the lubricating oil, the This lubricating oil filter first uses a coalescing separator to remove the deposited water and suspended water in the oil, and then removes the dissolved water in the oil through the vacuum degassing chamber.

2. Efficient degassing technology.

Improving the dehydration efficiency of the vacuum oil filter depends on reducing the absolute pressure of the degassing chamber, prolonging the degassing time, increasing the additional area and appropriately increasing the oil temperature. Compared with the method of spraying oil from the top to the bottom (other manufacturers use the method of drilling holes in the top partition, the hole diameter is about 1-2mm), the This vacuum oil filter adopts an inverted atomizer, and the oil is sprayed from the atomizer. After exiting, it rises and then falls, which greatly prolongs the residence time of the oil mist in the degassing chamber. The atomizer atomizes the oil into 50-250µm oil mist, which greatly increases the evaporation area and improves the degassing efficiency.

3. "One-key control" technology (optional).

   It adopts PLC intelligent controller, which can be started by pressing the "automatic" operation key, and the equipment runs fully automatically, minimizing manual operation errors.

4.  Heat recovery device (optional).

In order to reduce the heating load, the equipment with the processing capacity of This vacuum oil filter greater than 100L can be equipped with a heat recovery device. The hot oil discharged by the oil pump and the imported cold oil are exchanged for energy, and the heating efficiency is increased by more than 50%.

5.  High efficiency filtration system.

Adopting "gradual density" filtration technology, the highest filtration accuracy is 0.5μm, β≥1000, and the solid particle retention rate is as high as 99.99%. The first-stage filter has a filtering accuracy of 50µm, the second-stage filter has a filtration accuracy of 5µm, and the third-stage filter has a filtration accuracy of 1µm (optional).

6.  High density heater.

Increasing the oil temperature is beneficial for water molecules to obtain energy to escape the gravitational field of oil molecules and improve the dehydration efficiency of the vacuum oil filter. However, transformer oil is more sensitive to temperature. Excessive oil temperature will cause the carbon chain of oil molecules to break and destroy the oil structure. The This vacuum oil filter is equipped with a heat recovery device, which can recover most of the energy of the hot oil, thereby reducing the heating power. This vacuum oil filter also uses high-density heaters, and the heating load is as low as 2.5W/cm². The heater is equipped with liquid level detection to prevent the heater's surface temperature from being too high due to the heater's non-oil heating.

7.  Advanced liquid level control system.

The oil level control system of This vacuum oil filter is composed of main oil inlet solenoid valve, slave oil inlet solenoid valve and high liquid level sensor. When the oil temperature does not reach the set point, the heater continues to run, which greatly improves the heating efficiency.

8.  The front liquid level sensor of the vacuum pump prevents the vacuum pump from running out of oil. 

When the moisture or gas content in the oil is high, it is easy to produce a large amount of foam. If there is no anti-foam device, foam will enter the vacuum pump along with the gas, causing the vacuum pump to spray oil. When the condenser liquid level sensor detects the oil level, the vacuum system will stop working to prevent the vacuum pump from spraying oil.

9.  Free switching between inlet and outlet ports (optional).

When far away from the oil filter, it takes time and effort to replace the inlet and outlet oil pipes. The This vacuum oil filter is equipped with a free switching device for the inlet and outlet ports, which is easy and simple to connect the pipeline.

10. Power protection.

The This series vacuum oil filter is equipped with a power protection device. When the power supply voltage is higher than the set value, lower than the set value, or the power supply is out of phase or phase error occurs, the equipment will stop working to protect the electrical safety of the equipment.

11. Pressure protection.

The outlet of the oil pump is equipped with overflow and pressure detection devices.

When the filter is blocked or the oil outlet valve is not opened during the operation of the oil pump, the oil pump will automatically stop.

12. Motor overload protection.

When the vacuum pump motor or oil pump motor is overloaded, the equipment will automatically stop.

13. Humanized operation panel.

All equipment working status and fault status are displayed on the operation panel, which is greatly convenient for users.

IV. Working Principle

1.  The principle of coalescence and dehydration

There are two sets of filter elements with different functions inside the coalescing separator-coalescing filter element and separation filter element. When the oil flows through the coalescing separator, it goes through the four process stages of filtration, coalescence, sedimentation, and separation to achieve the functions of filtering particulate dirt and removing water.

The oil first flows through the coalescing filter element from the inside to the outside. The coalescing filter element is made of special glass fiber and other synthetic materials, and is specially formulated for turbine oil (turbine oil). It has good hydrophilicity. The coalescing filter element has the dual functions of filtering particulate pollutants and coalescing water. The innermost high-precision filter material first filters out particulate pollutants in the oil; the outer demulsification coalescence layer coalesces the tiny water droplets in the oil into water droplets. Larger water droplets will settle to the sump by their own gravity, and smaller water droplets will be carried by the oil to the separation filter element before it settles. The separation filter element is made of specially treated stainless steel mesh, which has good hydrophobicity. When the oil flows through the separation filter element from the outside to the inside, the small water droplets are effectively intercepted on the outside of the filter element, allowing only the oil to pass through. The water passes through to further separate the water.

2.  Principle of vacuum dehydration and degassing

The vacuum oil filter is designed according to the different saturated vapor pressures of water and oil. It consists of a primary filter, an oil feed pump, a heater, a vacuum separation chamber, a vacuum pump, a condenser, a fine filter, an oil discharge pump and an electrical cabinet. The vacuum pump draws out the air in the vacuum degassing chamber to form a vacuum. Under the action of the oil feed pump (or negative pressure), the oil is heated to 40-70℃ by the heater and enters the primary filter to eliminate larger particles, and then passes through the automatic oil Position valve, this valve is to automatically control the balance of the amount of oil entering the vacuum tank. The heated oil is sprayed into the vacuum container. The water in the oil quickly evaporates into water vapor and is continuously sucked into the condenser by the vacuum pump. The water vapor entering the condenser is cooled and then condensed into water and released. The dehydrated and degassed oil is discharged into the fine filter by the oil discharge pump, and the particulate impurities are filtered out through the filter element.

The vacuum oil filter is composed of several major components such as heating, filtering, degassing, condensation, and adsorption regeneration. It  includes heating system, filter system, vacuum atomization system, oil supply system and electrical control system. It can also be equipped with an acid removal and decolorization adsorption device.
