What components make up the power end of a power pump?

• A. Piston, sleeve, and tension rod
• B. Crankshaft, crosshead, and connecting rod
• C. Rotor, stator, and impeller
• D. Valve, motor, and gear

Answer: (B)

The power end of a power pump is primarily composed of components that convert rotational motion into linear motion, which is essential for the pump to function efficiently. In this case, the crankshaft, crosshead, and connecting rod work together to achieve this conversion. The crankshaft is responsible for converting the rotational energy from the motor into linear motion. The connecting rod then transmits that motion from the crankshaft to the crosshead, which ultimately drives the pistons or other pumping mechanisms. This entire setup is essential for the operation of positive displacement pumps, where the movement of the pistons creates pressure to move fluids. Other components listed in the options do not serve this specific function. While pistons and sleeves are indeed parts of a pump, they belong to the hydraulic end rather than the power end, which is focused on the conversion of motion. The rotor, stator, and impeller pertain to centrifugal pumps, and the valve, motor, and gear do not encompass the core components of the power end of a pump, but rather represent parts of different systems or configurations that do not relate to the same mechanism efficiently converting energy for pumping action.
