Prelim Quiz 2

What is the main working principle of a centrifugal purifier?

• Separation by gravitational force

• Separation by centrifugal force

• Breakdown of mixtures using heat

• Filtration through mesh screens

What happens when the bowl speed increases?

• Water remains mixed with oil

• Separation becomes more effective

• Solids pass through the outlet

• Oil and water mix evenly

Why is a sealing water system used in purifiers?

• To maintain an oil-water interface

• To remove sludge automatically

• To cool down the purifier bowl

• To filter solid particles

What is the function of the gravity disk?

• To adjust the separation interface

• To control the purifier speed

• To prevent oil overheating

• To collect heavy impurities

How does the clean oil outlet contribute to the system?

• It allows purified oil to exit

• It collects sludge for removal

• It prevents oil from thickening

• It mixes oil and water properly

What is the main role of the bowl periphery?

• To guide separated substances

• To heat the fluid before separation

• To mix oil and water uniformly

• To increase purifier efficiency

Why is the frame an important purifier component?

• It provides structural support

• It rotates to separate fluids

• It collects all impurities

• It controls flow pressure

What happens when the oil viscosity is too high?

• Oil separates instantly

• Purifier efficiency decreases

• Water is removed more quickly

• Bowl rotation slows down

Why must the oil temperature be regulated before purification?

• To reduce viscosity for better separation

• To allow water to mix easily

• To prevent solid deposits from forming

• To ensure complete oil filtration

What is the function of the feed pump?

• To supply oil at a controlled rate

• To remove excess water from oil

• To increase centrifugal force in the bowl

• To regulate purifier speed
