Question 176General Subjects - Assistant Engineer

The correct answer is D) prevent solid particles from entering the pump. Strainers are commonly used in hydraulic systems to protect the pump from solid particles that could enter the system and cause damage. The pump is a critical component in a hydraulic system, and preventing contaminants from reaching it is important to ensure the system's reliability and performance. Strainers help trap larger particles before they can reach the pump, which could otherwise cause wear, damage, or even failure of the pump. The other options are not the primary purpose of a strainer in a hydraulic system. Option A is more applicable to filters, while options B and C are not the main functions of a strainer.
