Questions and Answers

What creates a pulsating flow of fluid in a reciprocating pump?

The discharge valve

The cylinder head

The suction valve

The reciprocating motion of the piston (correct)

In a reciprocating pump, what happens during the suction stroke?

Piston moves away from the cylinder head, creating a low-pressure area (correct)

Fluid is forced out through the discharge valve

Fluid is drawn into the cylinder through the discharge valve

Piston moves toward the cylinder head, creating a high-pressure area

What is the function of suction and discharge valves in a reciprocating pump?

Controlling fluid entry and exit (correct)

Regulating pressure

Creating pulsating flow

Ensuring a constant flow rate
