Test 6 (T3.1)

The two main groups of hydraulic machines are:

• Pumps and fans

• Positive displacement and centrifugal

• Volumetric and Fluidodynamic

• Centrifugal and axial

What is the main principle behind volumetric hydraulic machines?

• They operate based on the expansion and contraction of gases

• They utilize the kinetic energy of water flow

• They work by trapping and displacing a specific volume of fluid

• They rely on the conversion of thermal energy into mechanical energy

For safety reasons, a circuit fitted with a volumetric pump must always have to be equipped with:

• A flow regulator valve

• A distributor valve

• A non-return valve

• A pressure relief valve

Which of the following is a common example of a volumetric hydraulic machine?

• Hydraulic press

• Pelton wheel turbine

• Wind turbine

• Waterwheel

What is the primary application of volumetric hydraulic machines?

• Energy saving

• Fast movements

• Lifting heavy loads

• Cooling industrial equipment
