Coalescing Separation Oil filter Question And Answer

Coalescing separation oil filter principle?

The unqualified oil enters the primary filter first, and the large particles of impurities are intercepted. The oil from which the large particles of impurities are removed is then sent to the fine filter by the oil pump. After the smaller impurities are removed in the fine filter, it continues to enter the coalescing separator. It utilizes the principle of molecular separation technology to analyze the pressure of the oil, eliminate the intermolecular binding force, so that the dissolved water and free water in the oil can quickly break the oil film and separate from the oil molecules to precipitate; so far, the dehydration and impurity removal are completed, so as to achieve the desired Moisture and cleanliness requirements.

Coalescing separation oil filter design?

The design of the coalescing-separation oil filter can be customized according to the needs of customers, and the model can be customized according to the product requirements of different fields, so as to meet the needs of customers to the greatest extent and improve the efficiency of oil filtration. At the same time, the coalescing and separating oil filter also has the advantages of simple operation and convenient maintenance. It has high oil filtering efficiency, reliable operation, energy saving and environmental protection, and is widely recognized and used by enterprises.

The difference between coalescing filter element and separation filter element?

The coalescing separation filter element is mainly designed for liquid-liquid separation, and it contains two kinds of filter elements, namely: coalescing filter element and separation filter element.
The coalescing separation filter element is mainly designed for liquid-liquid separation, and it contains two kinds of filter elements, namely: coalescing filter element and separation filter element. For example, in the oil dewatering system, after the oil flows into the coalescing separator, it first flows through the coalescing filter element, which filters out solid impurities and coalesces extremely small water droplets into larger water droplets. Most of the coalesced water droplets can be separated and removed from the oil by their own weight, and settle into the sump.
The role of the separation filter element:
Then the oil product flows through the separation filter element. Because the separation filter element has good lipophilic and hydrophobic properties, the water is further separated. Finally, the clean and water-free oil product flows out of the coalescer separator.

How often should the coalescing filter be replaced?

Generally speaking, the replacement time of the coalescing filter element depends on its actual working condition. In the oil-water separation industry, there is no specific standard for the replacement time of the coalescing filter element. But we can judge whether the filter element needs to be replaced through several factors.
1. When the flow rate suddenly drops compared to usual and the pressure rises, it is a signal that the coalescing filter element is clogged. The filter element needs to be replaced.
2. When the oil-liquid separation is not clean, the oil-water mixture still appears after separation and filtration several times, and the oil layer floats.
3. Observe the pressure gauge. After a period of use, if the pressure gauge alarms or the pressure is too high, it is also a signal to replace the filter element.
It is recommended to replace the coalescing separation filter element according to the quality and environment of the filtered oil or gas, so that the appropriate replacement time can be well determined, the service life of the filter element can be extended, and clean oil, gas and liquid can be filtered out, saving unnecessary downtime and replacement The coalescing and separating filter element significantly reduces maintenance costs while serving the coalescing and separating filter.
