There are many kinds of filter elements in construction machinery equipment. According to different working purposes, the filter elements are divided into air filters and oil filters.
The air filter element can filter dust and particles in the air, ensure that the air entering the cylinder is clean, has good filterability, and ensures that a sufficient amount of air enters the cylinder. It is one of the most important components in the intake and exhaust system. Work performance has a significant impact.
The filter paper of low-quality air filters is easy to be blocked by dust in a short period of time, and the filterability of the filter paper deteriorates quickly, and the filter paper of low-quality air filters generally has fewer "wrinkles" and a small filter area, so it cannot allow air to enter smoothly The combustion chamber of the engine leads to insufficient intake of the engine, a decrease in engine power, and an increase in fuel consumption.
1. Reliable structure
The air filter element is mainly composed of filter paper, skeleton, adhesive, sealing ring and end cap.
Compare SDLG filter elements and sub-factory filter elements:
|
Name |
SDLG air filter |
Sub-factory air filter |
|
Filter paper |
Made of resin-treated microporous filter paper, the number of corrugations and wave heights are designed reasonably. The filter paper is porous, loose, has certain mechanical strength and water resistance, high filtration efficiency and high air permeability. |
Made with ordinary filter paper, the number of corrugations and wave height are unreasonable. Poor mechanical strength and easy to deform. Poor filtering effect and air permeability will easily cause early wear and tear of the diesel engine; poor air permeability, high fuel consumption, and black smoke. |
|
Skeleton |
The skeleton adopts cathodic electrophoresis technology for surface treatment of rhombic mesh, which has strong corrosion resistance, high strength and is not easy to deform. |
Ordinary rhombic mesh that does not use cathodic electrophoresis technology for surface treatment is used, which is not resistant to corrosion and is easy to produce substances to pollute the filter element itself. Its strength is poor, and it is easy to deform and cause short circuit during use, which will cause early wear and tear of the engine. |
|
Glue |
Good bonding and sealing performance. It can prevent external dust, moisture, water, dirt, etc. from entering the cylinder block; it can better prevent the sealing ring, end cover and other parts from cracking and short circuit caused by mechanical vibration. |
Bonding and sealing performance is poor. It is easy to cause cracking of the bonded parts, and problems such as dust, particles and other sundries entering the cylinder block. |
|
Sealing ring |
The special sealing ring has excellent corrosion resistance, tear resistance and compression deformation resistance, and good resistance to ozone, sunlight and weather. The operating temperature range is -40~150 ℃ |
Inferior sealing rings have poor corrosion resistance, tear resistance and compression deformation resistance; poor ozone resistance, sunlight resistance and weather resistance. Use range -20~120 ℃. It is easy to cause air short circuit and early engine wear. |
|
End cap |
Special end caps, high-quality adhesives are bonded to the filter layer, high temperature resistance, medium resistance, and firm bonding. |
There is no check valve, which cannot effectively prevent oil backflow. |
2. Advanced technology
A good product is not only reflected in the raw materials and composition, but also the processing technology of the product. SDLG filter elements use mature processing technology and high-quality basic materials to ensure that every product produced is safe, efficient and reliable. The opening between the corrugation and the corrugation is relatively large, and there may be folded
3. Excellent performance
Reliable and reliable basic materials, combined with reliable processing technology, the performance of natural products will not be bad.
According to calculations: when using inferior air filters, the fuel consumption will increase by about 1-2 liters per 8 hours of work, and the annual cost will increase by about $300-$700. Much higher than the cost of purchasing original filter elements.
High filtration efficiency: the filtration efficiency of the original air filter can be as high as 99.5%
Safety pressure guarantee: It can resist temperature changes, water resistance and safety, and ensure that the intake humidity of the engine is suitable for the ignition point.
Graded filtration: The treated filter material can be graded and filtered to ensure the filtering effect and make the engine output efficiently.
Longer life and lower cost: About 70% of the early wear of the engine is related to the air filter, and its filtering effect plays an important role in the wear and life of the engine. According to the case: when the original air filter element is used and replaced in time as needed, the frequency of replacing the four sets of accessories can be effectively reduced.
