In a closed loop of piping, a centrifugal pump's main job is to:
Answer: Move fluid by adding velocity and pressure
A centrifugal pump imparts velocity to fluid, raising its pressure to move it.
Cavitation in a pump is caused by:
Answer: Vapor bubbles forming and collapsing in the fluid
Low pressure forms vapor bubbles that collapse violently, causing cavitation damage.
A check valve is designed to:
Answer: Allow flow in one direction only
A check valve permits flow one way and prevents backflow.
A V-belt drive transmits power primarily through:
Answer: Friction between the belt and pulley grooves
V-belts grip the sides of grooved pulleys and transmit power by friction.
Which type of bearing is best suited to support a rotating shaft under radial load?
Answer: Ball bearing
Ball bearings carry radial loads while allowing low-friction rotation.
Misalignment of two coupled rotating shafts will most likely cause:
Answer: Increased vibration and premature wear
Shaft misalignment produces excess vibration and accelerated bearing or seal wear.
The purpose of a lubricant between two moving metal surfaces is to:
Answer: Reduce friction and wear
Lubricants form a film that reduces friction and wear between moving parts.
