HEUBACH Colour Assistant Officer Interview Questions and Answers

Distillation is a process of separating components of a liquid mixture based on differences in boiling points.

• Distillation involves heating a liquid mixture to create vapor, then cooling the vapor to condense it back into liquid form.

• The different components in the mixture have different boiling points, allowing them to be separated through distillation.

• Types of distillation include simple distillation, fractional dist...read more

Cavitation is the formation of vapor bubbles in a liquid due to rapid changes in pressure, which can cause damage to machinery.

• Cavitation occurs when the pressure in a liquid drops below its vapor pressure, causing bubbles to form and collapse rapidly.

• This phenomenon can occur in pumps, propellers, and other machinery where rapid changes in pressure take place.

• The collapse of these bubbles can create intense shock wave...read more

Impellers are rotating components of a pump that transfer energy from the motor to the fluid being pumped.

• Impellers can be classified into different types based on their design and application, such as open, closed, semi-open, and vortex impellers.

• Open impellers have vanes that are attached to a central hub and are more prone to wear but are easier to clean.

• Closed impellers have vanes that are enclosed in a casing and ...read more

Cavitation is the formation of vapor bubbles in a liquid due to rapid changes in pressure, which can cause damage to equipment.

• Cavitation occurs when the pressure in a liquid drops below its vapor pressure, causing bubbles to form and then collapse rapidly.

• This phenomenon can occur in pumps, propellers, and other machinery where rapid changes in pressure take place.

• The collapsing bubbles can cause erosion and damage to...read more
