What type of contaminants do strainers specifically target in hydraulic systems?

Strainers in hydraulic systems are designed specifically to target solid particles. Their primary function is to filter out contaminants such as dirt, dust, rust, and metal shavings from the hydraulic fluid. By removing these solid particles, strainers help to maintain the cleanliness of the hydraulic system, thereby preventing potential damage to components such as pumps and valves that could be caused by abrasive materials.

While liquid contaminants, pneumatic contaminants, and chemical contaminants can indeed affect hydraulic systems, strainers are not designed to address these types. Liquid contaminants might involve water or other fluids that are not effectively managed by a strainer. Pneumatic contaminants pertain to gases or air, which are not relevant within the scope of a fluid filtration system. Chemical contaminants, which can include various liquids and reactive agents, typically require different methods of filtration or purification.

In conclusion, the effectiveness of strainers in removing solid particles is critical for the prolonged performance and reliability of hydraulic systems, making them an essential component in maintaining hydraulic fluid integrity.
