进油滤网/滤袜

进油滤网/滤袜是安装在燃油泵吸油口（通常在油箱内）的关键过滤部件。它作为第一道屏障，阻挡污垢、铁锈、金属屑和碎屑等颗粒污染物，防止其损坏燃油泵、喷油器或其他下游部件。该部件采用具有精确微米额定值的网状或织物过滤介质，封装在耐用的外壳中，设计用于持续浸没在燃油中。它在保持燃油流动的同时捕获有害颗粒，确保向发动机输送清洁燃油。

进油滤网/滤袜基于机械过滤原理工作。当燃油流过泵的吸油口时，滤网的网状或织物介质会物理截留大于其孔径的颗粒，同时允许清洁燃油通过。这防止了磨蚀性污染物进入泵机构，减少磨损并防止喷油器堵塞。设计通常采用褶皱或圆柱形结构，以最大化表面积并最小化流动阻力，保持稳定的燃油压力和流量。

The inlet strainer/sock operates on mechanical filtration principles. As fuel flows through the pump's intake, the strainer's mesh or fabric media physically traps particles larger than its pore size while allowing clean fuel to pass. This prevents abrasive contaminants from entering the pump mechanism, reducing wear and preventing clogging in fuel injectors. The design typically incorporates pleated or cylindrical configurations to maximize surface area and minimize flow restriction, maintaining consistent fuel pressure and volume.
