Excessive mechanical and pulsating vibrations developed in a main propulsion diesel engine may be more likely to cause damage to an attached __________.
A
scavenged air pump because it is designed for steady state operation rather than pulsating gas load
B
reciprocating scavenge pump because of its direct linkage to the crankshaft
C
centrifugal cooling water pump because of the close tolerances required between the impeller rim and the volute
D
gas driven turbocharger because it has a wide speed range, high operating temperatures and close tolerances.
