  • The role of air filtration and nanofiber filter media in heavy duty engines

    The role of air filtration and nanofiber filter media in heavy duty engines

    2019-08-03

    Engine air filters are developed based on filter performance requirements, vehicle operating environment, available space, filter media characteristics and production techniques. The design process includes analytical theory and empirical models describing the filter media properties and aerosol flow in the filter housing as well as the filter elements. Filter media carefully based on these models and simplified laboratory testing. The filter design was evaluated in great detail through a series of laboratory and field experiments. The role of the engine intake system has increased due to engine exhaust particulates and evaporative emission regulations. Engine life, engine emissions and fuel consumption depend on the design of the intake system and its performance. Providing an optimized solution to these requirements determines the trend of the filter. This has driven the need for smaller, more compact filters and more efficient permeability filter media. The efficiency can be significantly improved by applying a layer of nanofibers to the cellulose or synthetic substrate. The ISO fractional efficiency test method, in its final development stage, clearly shows the advantages of nanofiber filter media. The ISO fractional efficiency test method, in its final development stage, clearly shows the advantages of nanofiber filter media.

  • Filter filter material structure

    Filter filter material structure

    2019-07-26

    The structure of the filter material can be divided into two types: surface type and depth type. (1) surface type The surface type filter material is a fine filter mesh woven with a wire, and is also used in other forms such as wire winding. The filtration accuracy is determined by the size of the woven holes or the size of the wire gap. Any particles larger than the size or clearance of the aperture can not pass through just the ideal state, which is not practical in practice. The woven filter or wire is wound into a filter element having the same size of pores, and its filtering action only occurs on the surface of the filter screen, so it is called surface type filtration. As the dirt accumulates on the surface of the screen, its pores are constantly blocked, so that the pressure drop is gradually increased; the filtration efficiency is also lowered because the particles trapped in the mesh may be squeezed out of the mesh at any time. If it is desired to control the pressure drop within a certain range, the filter element should have a sufficiently large filtration area. This filter element can be reused after cleaning. (2) Deep filter media The deep filter media is made of fiber papermaking and has a certain thickness of filter media. The properties of this filter are quite different from those of surface type filtration. Its shape of the eyelet, the size is irregular, uneven, and the inner part is complicated by bending and twisting. Its filtering effect occurs not only on the surface of the filter medium but also in the depth of the filter medium, so it is called depth type filtration. Since the filter medium has a certain thickness and the passage is in all directions, its dirt holding capacity is much larger than that of the surface type filter, and the pressure drop is also much lower than that of the surface type filter. In addition, because of its wide range of pore size distribution, it can also filter out a large number of fine particles.   For the depth filter, the fiber diameter constituting the filter medium has a direct influence on the filtration efficiency and other properties. A filter layer made of a relatively small diameter fiber can form more through holes in a unit area, and can also form more channels in the interior. Therefore, its filtration efficiency and dirt holding capacity are higher than those of the coarser fiber. For the same reason, its pressure drop is also smaller than the latter. Therefore, the filter element made of fine fiber has a long working life.

  • The role of the air filter and the replacement cycle

    The role of the air filter and the replacement cycle

    2019-06-28

    An air filter is a device that purifies air. The air filter removes suspended particulate matter from the air entering the cylinder to reduce the wear of the cylinder and piston and piston ring to extend the life of the component. The air filter is a consumable item and is usually replaced once every 10,000 kilometers. The main requirements of the air conditioner are high filtration efficiency, low flow resistance, and continuous use for a long time without maintenance. · It is important to choose the right filter. Why do you say this? The main reason is that the bacteria dust in the summer air is abnormally active, and in other weathers, the filter may not feel anything, but the filter that is not suitable in summer will Shows the problem, because if you have pollen allergies and don't choose pollen filters or filters that filter well, then you are likely to be miserable while driving, and the summer air filter is better. For the protection of the body, pay special attention to the more hair, and a good filter can filter a lot of hair and dust, because the summer dry explosion often the road dust will float so good filter for summer road dust filter It is very good.

  • Filter PL420 can't replace filters PL421

    Filter PL420 can't replace filters PL421

    2019-06-21

    In the past, the PL420 was used as the first primary filter for the fuel tank girders. There is no pressure. The common rail is pressurized, and the PL420 is under negative pressure. Before the appearance of the electronic pressure pump, the transparent cup is very safe, there is no pressure damage to the transparent cup, but with the advent of the electronic pressure pump, the engine's two coarse filters change from negative pressure to 4 positive pressures or even greater pressure. The old-fashioned PL420 transparent cup has the risk of oil leakage. Some OEMs changed the PL420 on the engine to the PL421 without a cup. However, some OEMs did not consider this problem. They still loaded the PL420. (There are now Delong) there are design risks. It is recommended to use the filter PL421 for models equipped with an electronic pump. Filters PL420 and PL421, we can provide, if you need, please feel free to contact us.

  • What are the effects of fuel filter replacement and non-replacement?

    What are the effects of fuel filter replacement and non-replacement?

    2019-05-31

    What are the effects of fuel filter replacement and non-replacement? Gasoline filtration is one of the common filter products, the main function is to remove impurities from gasoline. If the fuel filter is too dirty or blocked, the main performance is: when the fuel is added, the power is slower, or it can't get up, the car is difficult to start, sometimes it takes 2-5 times to catch the fire. Most engines are equipped with disposable, non-removable paper filter fuel filters. The replacement cycle is generally 10,000 kilometers. If you add less gasoline, it is not a problem to replace one with 15000-20000 kilometers. The filter has an inlet and outlet arrow mark, and should not be reversed when replacing. The fuel filter is to filter the impurities in the gasoline you usually add. It takes a long time. Your fuel filter is full of dirt, dirt and dregs. Therefore, it is recommended to change the number of kilometers. If you don't change it, or delay the change, it will definitely affect the performance of your car; for example, the oil road is not smooth, the car is not motivated, the time is long, the filter performance of the steam filter is greatly reduced, and finally the engine is damaged chronically, and even the engine is overhauled. If you don't change it, it will definitely bring a lot of damage to the car.
