In modern industrial production, the quality of various oils such as lubricating oil and hydraulic oil plays a crucial role in the stable operation and production efficiency of equipment. During the use of oil, it is inevitable that pollutants such as moisture and impurities will be mixed in, which not only reduces the performance of the oil, but may also cause serious damage to the equipment. The coalescence dehydration oil filter，as an efficient oil purification equipment, has been widely used in the industrial field.

Working principle of coalescence dehydration oil filter

The coalescence dehydration oil filter is mainly based on the principles of coalescence and separation to achieve dehydration and purification of oil products. When oil containing moisture and impurities passes through the oil filter, it first passes through the coalescing filter element. The coalescence filter element has a special structure and material that can adsorb and coalesce tiny water droplets in oil. These tiny water droplets gradually coalesce into larger ones under the action of the coalescence filter element.

Subsequently, the oil enters the separation filter element. Due to the different densities of water and oil, larger water droplets that coalesce under the action of the separation filter will settle at the bottom of the filter, thereby separating from the oil. And impurities are intercepted by the filter element, further ensuring the purity of the oil. Through this method, the coalescence dehydration oil filter can efficiently remove moisture and impurities from the oil, restoring the oil to a good working condition.

Application in the petrochemical industry

Crude oil extraction and transportation process

During the process of crude oil extraction, crude oil is usually mixed with a large amount of formation water. If these moisture are not removed in a timely manner, it will not only increase transportation costs, but may also cause corrosion to the equipment during subsequent processing. The coalescence dehydration oil filter can perform preliminary dehydration treatment on crude oil at the wellhead or gathering station, reducing the water content in the crude oil to a standard that meets transportation and processing requirements. For example, in some offshore oil fields, due to limited space, efficient and compact dehydration equipment is required. The small volume and strong processing capacity of the coalescence dehydration filter oil machine precisely meet this demand, ensuring stable extraction and transportation of crude oil.

Application in the refining process

In refineries, various oil products are also prone to water and impurities during the refining process. Agglomeration dehydration oil filters are widely used in the refining process of intermediate and finished products. For example, in the production process of diesel, the water and mechanical impurities in diesel can be removed through a coalescence dehydration oil filter, improving the quality of diesel and making it comply with relevant national standards. At the same time, for the production of lubricating base oil, the coalescence dehydration oil filter can effectively remove impurities such as water and residual catalysts, improve the quality of lubricating base oil, and lay the foundation for the subsequent production of high-quality lubricating oil.

Application in the power industry

Purification of Transformer Oil

Transformers are key equipment in the power system, and the quality of transformer oil directly affects the safe operation of transformers. During long-term use, transformer oil will absorb moisture and impurities from the air, leading to a decrease in its insulation performance. The coalescence dehydration oil filter can regularly purify transformer oil, remove moisture and impurities, and restore the insulation performance of transformer oil. This can not only extend the service life of transformers, but also reduce the risk of power outages caused by transformer failures, ensuring the stable operation of the power system. For example, in some large substations, automated coalescing dehydration oil filter systems are used, which can monitor the quality of transformer oil in real time and automatically start the oil filter for purification treatment as needed, greatly improving operation and maintenance efficiency.

Maintenance of hydraulic oil system

In some large equipment in the power industry, such as hydraulic control systems for steam turbines, the cleanliness and moisture content of hydraulic oil are crucial for the normal operation of the equipment. The coalescence dehydration oil filter can perform online filtration and dehydration treatment on hydraulic oil, ensuring that the hydraulic oil is always in good working condition. When the moisture and impurities in hydraulic oil exceed the standard, the coalescence dehydration oil filter can remove them in a timely manner, avoiding equipment failures caused by hydraulic oil pollution, such as valve jamming, actuator failure, etc., thus ensuring the reliable operation of power production equipment.

Application in the mechanical manufacturing industry

Machine tool lubrication system

In mechanical manufacturing enterprises, machine tools are the core production equipment. The lubrication system of machine tools plays a crucial role in ensuring their accuracy and service life. Machine tool lubricating oil is prone to impurities such as cutting fluid, moisture, and metal debris during use. The coalescence dehydration oil filter can be installed in the circulation circuit of the machine tool lubrication system to filter and dehydrate lubricating oil in real time. By removing pollutants from lubricating oil, the wear of machine tool components can be effectively reduced, ensuring the machining accuracy of the machine tool and improving production efficiency. For example, in some high-precision CNC machining processes, using a coalescence dehydration oil filter to purify lubricating oil can ensure that the dimensional accuracy and surface quality of the machined parts meet strict requirements.

Maintenance of hydraulic equipment

Various hydraulic equipment, such as hydraulic presses and injection molding machines, are widely used in the mechanical manufacturing industry. The stability and reliability of hydraulic systems directly affect the continuity of production and product quality. The coalescence dehydration oil filter can effectively remove moisture and impurities from hydraulic oil, prevent oxidation and emulsification of hydraulic oil, and extend the service life of hydraulic oil. At the same time, maintaining the cleanliness of hydraulic oil can also reduce the wear and tear of hydraulic pumps, valves, and other components, lower equipment failure rates, and improve equipment operating efficiency. In the maintenance of some large hydraulic presses, regularly using a coalescence dehydration oil filter to treat hydraulic oil can significantly reduce the number of equipment repairs and maintenance costs.
