Question 1050 Deck Safety

The correct answer is D) store fluid under pressure. A hydraulic accumulator is a device designed to store fluid under pressure. This stored energy can then be used to supplement the hydraulic system when needed, such as during periods of high demand or when the main pump is not operating. This helps to maintain system pressure and ensure a continuous supply of hydraulic fluid. The other answer choices are incorrect because they do not fully capture the primary function of a hydraulic accumulator. While a hydraulic accumulator may act as a fluid reservoir (A), provide overpressure relief (B), or replenish fluid to a system (C), its main purpose is to store fluid under pressure (D).
