Question 368General Subjects - Assistant Engineer
70% to passWhat type of pump is shown in the illustration? Illustration GS-0144
ADeep well centrifugal pump
BSimplex reciprocating pump
CTriple screw rotary pump
DDouble screw rotary pump
AI Explanation
The correct answer is C) Triple screw rotary pump. The illustration GS-0144 depicts a triple screw rotary pump, which is a type of positive displacement pump used in marine applications. Triple screw pumps are characterized by their three intermeshing screw-like rotors that create a smooth, pulseless flow of the pumped fluid. This design makes them well-suited for handling a variety of liquids, including lubricating oils, fuels, and other fluids found on ships and boats. The other options are not correct because a deep well centrifugal pump (A) has a different impeller design, a simplex reciprocating pump (B) uses a piston mechanism, and a double screw rotary pump (D) has only two rotors instead of three.
