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
Why is excessive flow into the purifier a concern?
It speeds up the oil discharge process
It allows complete sludge removal
It reduces separation efficiency
It increases bowl rotation speed
What does adjusting the gravity disk achieve?
It modifies the separation boundary
It filters solid particles
It slows down oil discharge
It removes all impurities
What happens if the density difference between oil and water is minimal?
Oil becomes clearer faster
Separation is less effective
Purifier speed decreases
Water is completely removed
Why is the viscosity of oil important in purification?
It prevents water from separating
It affects the separation process
It improves sludge removal
It increases the bowl rotation
Why is monitoring the oil content in discharged water important?
To comply with environmental standards
To improve oil purity further
To ensure stable purifier speed
To increase flow rate
