进油滤网/滤袋

Inlet strainer/sock is a protective filtration component in fuel pumps that prevents contaminants from entering the fuel system.

技术定义与适配语境
典型 进油滤网/滤袋 会按材料、尺寸公差、适配关系和失效风险在 汽车制造 中评估。

The inlet strainer/sock is a critical filtration component installed at the fuel pump's intake point, typically within the fuel tank. It functions as a primary barrier against particulate contaminants such as dirt, rust, metal shavings, and debris that could damage the fuel pump, injectors, or other downstream components. This component features a mesh or fabric filtration medium with precise micron ratings, housed in a durable casing designed for continuous immersion in fuel. It maintains fuel flow while capturing harmful particles, ensuring clean fuel delivery to the engine.

定义
The inlet strainer/sock is a critical filtration component installed at the fuel pump's intake point, typically within the fuel tank. It functions as a primary barrier against particulate contaminants such as dirt, rust, metal shavings, and debris that could damage the fuel pump, injectors, or other downstream components. This component features a mesh or fabric filtration medium with precise micron ratings, housed in a durable casing designed for continuous immersion in fuel. It maintains fuel flow while capturing harmful particles, ensuring clean fuel delivery to the engine.
工作原理
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.

常见问题

How often should an inlet strainer/sock be replaced?

Replacement intervals vary by application but typically range from 30,000 to 100,000 kilometers in automotive use, or during scheduled fuel system maintenance. Signs of clogging or reduced fuel flow indicate immediate replacement.

What happens if the inlet strainer becomes clogged?

Clogging restricts fuel flow to the pump, causing symptoms like engine hesitation, power loss, stalling, or pump cavitation. Severe cases can lead to pump overheating and premature failure.
