ASL electrostatic oil filter It is a kind of equipment used to filter pollutants, and its filtering principle is based on electrostatic effect. It is usually used in the fields of oil recovery and treatment system, lubricating oil filtration in the engine, machining coolant treatment, etc. The following will describe in detail ASL Electrostatic oil filter Its principle and filtering method for pollutants.

ASL electrostatic oil filter is mainly composed of filter element, filter element chamber, power supply device and control system. Filter element is a key component, including oil filtering medium and electrode. The filter element cavity is used to fix the filter element and oil flow. The power supply unit provides high voltage for the filter element, and the control system is used to control the working state of the power supply unit.

The filtering principle of ASL electrostatic oil filter is based on electrostatic adsorption and electrostatic separation. The goal is to remove solid particles, water and other impurities in the oil.

Specifically, when the contaminated oil flows through the filter element, a high voltage is applied to the electrode of the filter element. Under the action of high voltage, the filter element electrode generates a strong electrostatic field. This electrostatic field will absorb impurities in the oil, such as solid particles and water. The solid particles are positively charged, while the filter element electrode is negatively charged. The generation of electrostatic field makes the solid particles subject to the electric adsorption effect, thus being captured by the filter element.

In addition, the electrostatic oil filter can also remove water through the electrostatic separation principle. Water in oil mainly exists in the form of suspension. Since the water molecule contains positively charged hydrogen ions, and the filter element electrode has negative charges, the positively charged hydrogen ions will be adsorbed by the filter element under the action of electrostatic field, so that the water in the oil can be separated.

During the whole process, the electrostatic oil filter continuously accumulates solid particles and moisture, which leads to the gradual blockage of the filter element. In order to maintain the filtering efficiency of the oil filter, the filter element can be cleaned regularly. When cleaning the filter element, a liquid cleaner can be used to flush the accumulated pollutants out of the filter element through the back flushing of the filter element cavity to restore its filtering effect. When the filter element can no longer restore its original effect, it is necessary to replace the filter element.

ASL electrostatic oil filter has the following advantages over traditional oil filter:

Efficient filtration: The generation of electrostatic field enables ASL electrostatic oil filter to efficiently capture solid particles, water and other impurities, and provide cleaner oil.

Durable: The filter element of ASL electrostatic oil filter is specially designed, which can be used for a long time and maintain high filtration efficiency.

Economical and energy-saving: Compared with traditional oil filters, ASL electrostatic oil filters have lower energy consumption, longer service life, no need to replace filter elements frequently, and lower maintenance and operation costs.

Environmentally friendly: ASL electrostatic oil filter does not need chemical auxiliary filtration, and does not pollute the environment. AlfaLaval centrifuge

It should be noted that although ASL electrostatic oil filter has a good effect in filtering pollutants, its effect may not be satisfactory for some specific pollutants, such as acidic substances or viscous pollutants. Therefore, in practical application, it is necessary to select an appropriate filtering method according to the specific situation.

In general, ASL electrostatic oil filter can efficiently filter solid particles, water and other impurities in oil through the principle of electrostatic adsorption and electrostatic separation. It has the advantages of high efficiency, durability, economy, energy conservation and environmental friendliness. It is suitable for a variety of applications and plays an important role in ensuring the normal operation of equipment and extending the service life of oil.
