Introduction to plastic oil and gas separator lattice product
As the core component of the engine oil and gas separation system, the plastic oil and gas separator grid builds a "purification line" for the efficient operation of the power system with precision structure and weather-resistant materials, and plays a key role in automobiles, engineering machinery and other fields.
In terms of material selection, reinforced PA66+GF30 composite material is used, which has high strength and oil resistance. This material has undergone high-temperature aging test at 150℃, and its mechanical properties retention rate exceeds 85%, which can withstand long-term high-temperature environment of the engine compartment. At the same time, it has passed a 1000-hour fuel soaking experiment, and has no swelling or cracking. It can withstand the corrosion of gasoline and engine oil, etc., ensuring structural stability under complex working conditions. Compared with traditional metal materials, the weight is reduced by 40%, effectively reducing the engine weight and helping to save energy and reduce emissions.
Separation efficiency is its core competitiveness, which is derived from the unique multi-layer lattice structural design. The first layer is a spiral flow guide grid. After the oil and gas mixture enters, it rotates at a high speed along the spiral channel. Centrifugal force is used to throw large-particle oil droplets toward the wall, and the initial separation efficiency is 60%; the second layer of honeycomb interceptor grid, 200 micro-scale honeycomb holes of 200 micro-scale honeycomb holes of 200 diameters per square centimeter form a "gas barrier", allowing oil mist with a diameter of 5-10μm is adsorbed when passing through the porous structure, and the secondary separation efficiency is increased to 85%; the third layer of wavy coalescing grid guides the airflow to turn multiple times through the wave curved surface, so that the tiny oil droplets accumulate into large oil beads during collision, and the final separation efficiency is stable to more than 98%, greatly reducing engine oil losses and exhaust pollutant emissions.
Structural details demonstrate engineering ingenuity. The edge of the grating adopts a stepped seal design, which forms a double sealing surface after being assembled with the separator housing. With a high-temperature resistant sealing ring, the leakage rate is controlled below 0.01%, to prevent unseparated oil and gas from directly rushing into the combustion chamber. The internal flow guide ribs are arranged in an inclined manner at 45°, which not only reduces the airflow resistance (pressure loss ≤3kPa), but also extends the residence time of oil and gas in the grid to ensure sufficient separation. A 0.5mm expansion gap is reserved between each grid unit to prevent the structure from deformation at high temperatures from blocking the airflow channel.
The convenience of installation and maintenance is also outstanding. The standardized snap-on design is suitable for mainstream engine models. No special tools are required for installation. The fixing can be completed by pressing the alignment hole, and the assembly time is shortened to 1/3 of the traditional bolt connection. The surface of the grating is treated with an anti-stick coating to reduce oil stain adhesion. During daily maintenance, you only need to reversely purge with a high-pressure air gun to remove residual oil stains on the surface without disassembling the entire separator. In addition, the product supports modular replacement, and there is no need to replace the overall components when a single grid is damaged, which greatly reduces the repair costs.
