The working principle of oil bath air filter, who knows thank you.

The oil-bath air filter has a simple structure, and oil and metal wires are the main filtering materials. Principle: The rapidly rotating airflow sucks up the engine oil, and uses the viscosity of the engine oil to absorb the impurities in the air, while the oil particles generated by the engine oil are adsorbed and intercepted by the steel wire filter element, thus effectively removing the impurities in the air and achieving the filtering effect. The filtration process is that when the air containing impurities passes through the engine oil chassis, the impurities in the air contact with the engine oil and make it adhere to the oil film. The air then passes through a wire filter. Impurities wrapped in oil film adhere to metal wires. In order to realize the first-stage air filtration, in principle, single-stage oil filtration cannot be used to filter the machine intake. More commonly, it is used in combination with a dry paper filter. In this way, the air after coarse filtration enters the filter element (paper) for fine filtration, and then enters the engine to do work. The filtration effect is not as good as that of dry type, but it is more economical to change the filter element frequently. The disadvantage is that the air intake resistance is large. If the match is improper, it is easy to hold up the car.

Among them, the following oils can be used as waste engine oil or hydraulic oil for machine maintenance and replacement. ? Water won't do. Because there is no adhesion.

In addition, the working environment of freight cars is poor, and the air intake quality can not meet the requirements, which directly affects the service life of locomotives. Replacing the paper core of the original car is expensive and inconvenient to maintain. Many car owners adopt the method of adding one-stage oil bath air filtration to the original car air filtration. The effect is very good. Very cost-effective. It's better than replacing the whole component.
