Cuestionario sobre Circuitos Hidráulicos

Which of the following components converts hydraulic energy into rotational mechanical energy?

• Hydraulic Cylinder

• Hydraulic Motor

• Pressure Intensifier

• Heat Exchanger

What is the main purpose of this element in a hydraulic circuit?

• Filter contaminants from the hydraulic fluid

• Evacuate to the tank the excess fluid when not needed

• Store hydraulic fluid at high pressure to provide extra energy when needed

• Improve the cooling process of the fluid

In a hydraulic circuit, this element is essential because:

• They increase the flow rate of the hydraulic fluid

• They prevent contaminants from entering and damaging components

• They cool the hydraulic fluid

• They increase the pressure of the fluid

Which heat exchanger is used for applications which have a high cooling demand:

• 
• 

Which of the following statements is true about hydraulic hoses compared to hydraulic pipes?

• Hoses are more rigid and cannot bend

• Pipes are used for applications that require flexibility

• Hoses are flexible and suitable for moving parts, while pipes are rigid and often used for fixed installations

• Pipes can only transport hydraulic fluid at low pressures

If an accumulator is emptied in 5 s, which is the most suitable assumption for the process?

• Adiabatic

• Isothermal

• Isochoric

• Polytropic

What role does this element play in a hydraulic circuit?

• Reduces the system pressure to prevent damage

• Converts hydraulic energy into rotational energy

• Increases the pressure in a specific part of the circuit

• Provides flow to the circuit from the tank

In hydraulic motors, the rotation speed is mainly controlled by:

• Adjusting the pressure relief valve

• Regulating the flow rate

• Using a direcctional valve

• Increasing the pressure at the inlet

What kind of filter is commonly used before the directional valves and actuators and after the pump?

• Screen Filter / Strainer

• Suction Filter

• Return Line Filter

• High Pressure Filter

An accumulator in a hydraulic circuit is typically charged with:

• Only hydraulic fluid

• Compressed air or nitrogen

• Water to increase cooling capacity

• Lubricating oil
