Which of the following are the beneficial effects of air vessel fitted to delivery side of a reciprocating pump?
1. Constant rate of discharge can be ensured
2. Power consumption can reduced
3. Discharge can be increased
4. Constant velocity of the piston can be ensured. Select the correct answer using the codes given below
Option (A)
1 and 4
Option (B)
1 and 2
2 and 4
1 and 3
Correct Option:
Question Solution:
The function of air-vessel are:-
(1) On suction side
(i) To reduce accelerating head. This will reduced the total vacuum head reduced the possibility of separation for supplying accelerating head
(ii) Pump can be run on higher speed
(iii) Length of suction pipe below the air vessel can be increased
(2) On delivery side
(i) To reduce the accelerating head and affecting in large amount of power consumed in supplying the accelerating head
(ii) A uniform rate of discharge is ensured
