The potential negative impact of a clogged inlet strainer in a hydraulic system is?

A clogged inlet strainer can significantly hinder the flow of hydraulic fluid into the pump. When the strainer is blocked, it restricts the volume of fluid that can enter the pump, leading to reduced efficiency. The pump may struggle to maintain adequate suction, which can cause it to work harder than normal to draw in fluid. This increased workload not only reduces the pump’s efficiency but can also lead to wear and tear over time, shortening the pump’s lifespan.

While the other potential impacts mentioned in the options could occur as a consequence of increased strain on the pump—such as increased fluid temperature due to friction and consistent actuator performance—these are more indirect results. The primary and immediate consequence of a clogged inlet strainer is indeed the reduced efficiency of the pump. This underscores the vital role of a properly functioning inlet strainer in maintaining the health and efficiency of the hydraulic system.
