With the rapid development of the times and the widespread popularity of automobiles, the demand for filters continues to increase. It has now become an industry in which supply exceeds demand, and its production capacity cannot keep up with the growth rate of demand.
Regarding filters, many car owners believe that the heavier the filter, the better the materials and the better the quality. In fact, this is not the case. The function of the filter is to filter, and filtration mainly depends on the following indicators, namely There are six indicators such as weight, thickness, pore size, air permeability, stiffness, and bursting resistance. These indicators all have certain values. Exceeding or failing to reach them will lead to differences in product quality. The above six indicators are also It is not directly proportional to the quality of the filter, so it is a wrong concept that the heavier the filter, the better.
For example, pore size, air permeability, stiffness, and bursting resistance. These indicators mainly depend on the quality and characteristics of the filter material. These are not directly related to the weight of the filter. In addition, what kind of material is selected for the filter? , what kind of structure is adopted is determined by the needs of the car model used by the filter itself. It is not that the material in the middle is more suitable for the car model used.
Let's talk about one thing, such as the sealing performance of the filter, which generally depends on the performance of the sealing ring and the strength of the shell. It has nothing to do with the weight of the filter. Many people may also say that the strength of the shell Isn't it true that the thicker the shell, the greater the strength? The thicker the shell, the higher the weight. In fact, this statement is not wrong, but it is not complete. Why? Because the filter has a working pressure range. As long as the filter The pressure-bearing capacity is actually sufficient within its working range, but if thicker materials are added, on the one hand it will be unnecessary cost, on the other hand, the heavy filter will cause unnecessary load on the car, which will cause environmental protection and cost-effectiveness. All of them are unreasonable. As for the sealing ring, whether it is tight or not depends on the nature of the material and has nothing to do with the weight.
Take the oil filter as an example. For the same product, if the filter wants to be heavier, the weight of the filter material needs to be heavier. If the weight is heavier, it is likely to increase significantly. The flow resistance causes the amount of engine oil to be insufficient for heavy driving during the driving of the car, resulting in a lack of engine oil while the car is driving, resulting in severe wear and tear as a result of insufficient lubrication.
Therefore, when choosing a filter, it is really not that the heavier the better, but the one that is suitable. When choosing a filter, you must also pay attention to the brand. Quality is important, and the quality of the brand is generally guaranteed.
