An air vessel is a close chamber having an opening at its base through which the liquid may flow into the vessel or it may flow out from the vessel air vessel fitted to suction and delivery pipes of a single-acting pump. The air vessel fulfill following functions.
(i) It continuous supply of provides liquid at a uniform rate.
(ii) It saves considerable amount of work in overcoming the frictional resistance in suction and delivery pipes.
(iii) It facilitates pump to run at a high speed without separation.

Air Vessels in Reciprocating Pump Installations

Air vessels are essential components in reciprocating pump installations. They serve a multitude of purposes, including reducing pulsations and pressure fluctuations in the system, increasing pump efficiency, and reducing energy consumption. The following statements describe air vessels in reciprocating pump installations:

1. The air vessels are fitted on both suction and delivery sides.
Air vessels are typically fitted at the discharge side of the pump to absorb the pressure fluctuations caused by the reciprocating motion of the pump. However, they can also be fitted on the suction side to provide a cushioning effect and reduce the suction head loss.

2. The air vessels are fitted away from the pump cylinder.
The air vessel should be located as far away as possible from the pump cylinder to maximize its effectiveness in absorbing pressure fluctuations. This distance depends on the size and type of pump and the operating conditions.

3. The air vessels save energy by reducing friction loss.
Air vessels act as a buffer between the pump and the system, reducing the amount of energy required to overcome friction losses. This results in significant energy savings and increased pump efficiency.

Conclusion
In conclusion, air vessels are an essential component of reciprocating pump installations. They serve a variety of purposes, including reducing pulsations and pressure fluctuations, increasing pump efficiency, and reducing energy consumption. The correct statements regarding air vessels are that they are fitted away from the pump cylinder and save energy by reducing friction loss.
