Ramsay Test Ramsay Hydraulics & Pneumatics

Question 1

According to Pascal's Law, when pressure is applied to a confined fluid, it is transmitted:

Accepted Answer

Equally in all directions

Answer

Pascal's Law states that pressure applied to a confined fluid is transmitted equally in all directions throughout the fluid.

Question 2

What is the primary function of a hydraulic accumulator?

Accepted Answer

To store energy and dampen pressure fluctuations

Answer

A hydraulic accumulator stores pressurized fluid to dampen pressure spikes and provide supplemental flow on demand.

Question 3

In a hydraulic system, which component converts mechanical energy into hydraulic energy?

Accepted Answer

Pump

Answer

A hydraulic pump converts mechanical energy from a motor or engine into hydraulic energy by pressurizing the fluid.

Question 4

What does a relief valve do in a hydraulic system?

Accepted Answer

Limits maximum system pressure to prevent damage

Answer

A relief valve limits maximum system pressure by diverting excess flow back to the reservoir when the set-point pressure is reached.

Question 5

Which type of hydraulic pump uses meshing gears to displace fluid?

Accepted Answer

Gear pump

Answer

A gear pump traps fluid between meshing gear teeth and the housing, displacing it from inlet to outlet as the gears rotate.
