What is the purpose of strainers in hydraulic systems?

The purpose of strainers in hydraulic systems is to prevent solid particles from entering the hydraulic circuit. These devices are designed to filter out contaminants, such as dirt, debris, and any other particulate matter that could potentially damage or obstruct hydraulic components like pumps, valves, and actuators. By maintaining the cleanliness of the hydraulic fluid, strainers help ensure the smooth operation of the system, extend the lifespan of components, and reduce maintenance costs.

Other choices mention functions that do not align with the primary role of strainers. While lowering fluid pressure, cooling fluids, and enhancing lubrication are important aspects of hydraulic systems, these functions are achieved through different components and mechanisms. Strainers specifically focus on the filtration of particulates, making them crucial for protecting the integrity and performance of the entire hydraulic system.
