Function of air vessel provided in a reciprocating pump is to_________________?
Correct answer: A. Reduce discharge fluctuation
- A. Reduce discharge fluctuation
- B. Reduce the danger of cavitation
- C. Avoid the necessity of priming
- D. Increase the pump efficiency
Explanation
An air vessel stores liquid during part of the stroke and releases it during another part, smoothing the pulsating discharge of a reciprocating pump. It can also reduce friction and cavitation risk, but discharge smoothing is its primary function.
