Question 303General Subjects - QMED
70% to passWhen a reciprocating pump is operating at maximum speed, the cushioning valves should be _______________.
Awide opened
B3/4 opened
Chalf opened
Dalmost completely closed
AI Explanation
The correct answer is D) almost completely closed. When a reciprocating pump is operating at maximum speed, the cushioning valves should be almost completely closed. This allows the cushioning valves to effectively absorb the shock and pressure spikes generated by the rapid movement of the pump's piston, preventing damage to the pump and associated piping. If the cushioning valves were wide open (A), 3/4 opened (B), or half opened (C), they would not be able to provide adequate cushioning and the pump could be at risk of damage.
