Hydraulic Components

What is the primary function of a hydraulic reservoir?

• Generate hydraulic pressure

• Store hydraulic fluid

• Filter contaminants from the fluid

• Regulate fluid temperature

What is the purpose of a filter in a hydraulic system?

• Regulate fluid temperature

• Increase fluid viscosity

• Remove contaminants from the fluid

• Control fluid pressure

Answer explanation

Filters in a hydraulic system are designed to remove particles and contaminants from the hydraulic fluid to maintain system cleanliness.

What is the function of a strainer in a hydraulic system?

• Store hydraulic fluid

• Remove large contaminants from the fluid

• Control fluid pressure

• Regulate fluid temperature

Answer explanation

Strainers are used to capture larger particles and prevent them from entering the hydraulic components.

What is the purpose of a heat exchanger in a hydraulic system?

• Remove contaminants from the fluid

• Store hydraulic fluid

• Regulate fluid temperature

• Control fluid pressure

Answer explanation

Heat exchangers help control the temperature of the hydraulic fluid by dissipating excess heat.

Which component is responsible for conducting hydraulic fluid between different parts of the system?

• Reservoir

• Filter

• Strainer

• Conductor

Answer explanation

Conductors are the components that carry hydraulic fluid between various parts of the hydraulic system.

In a hydraulic system, what is the purpose of a pressure relief valve?

• Remove contaminants from the fluid

• Regulate fluid temperature

• Control fluid pressure

• Store hydraulic fluid

Answer explanation

A pressure relief valve regulates and limits the maximum pressure in the hydraulic system to prevent damage.

What is the significance of maintaining proper fluid cleanliness in a hydraulic system?

• Increases fluid viscosity

• Reduces system efficiency

• Enhances heat exchange

• Prevents component wear and damage

Which type of filter is commonly used to remove very fine particles from hydraulic fluid?

• Magnetic filter

• Bag filter

• Cartridge filter

• Strainer

What is the primary role of baffles in a hydraulic reservoir?

• Facilitate fluid conduction

• Enhance heat exchange

• Separate air from the fluid

• Prevent fluid sloshing

Answer explanation

Baffles in a reservoir help prevent the fluid from sloshing excessively during movement.

Why is it important to monitor and maintain the proper fluid level in a hydraulic reservoir?

• To regulate fluid temperature

• To prevent fluid contamination

• To ensure proper fluid conduction

• To avoid cavitation and air ingestion

Answer explanation

Maintaining the proper fluid level in a reservoir helps prevent cavitation and the ingestion of air, ensuring the proper functioning of the hydraulic system.
