Installation and Startup(Engines) - Module

Question 1

True or False;
The engine installation affects how well the engine is fastened to the foundation, but does not affect the engine life.

Answer 1

False
-If the engine foundation and mounting methods aren’t adequate, several problems such as machine misalignment, machine and building vibration, and machine torsional stress could arise.

Question 2

True or False;
Vibrations from one machine can be transferred to other machines in the building.

Answer 2

True

Question 3

True or False;
A good foundation helps keep the bearing bores of the engine block in-line if the machine has a good initial alignment.

Answer 3

True

Question 4

True or False;
An inertia block is an engine that has the block reinforced with heavy ribs or a heavy skid filled with grout.

Answer 4

False
-An inertia block, also known as the engines foundation, should have a mass at least 2.5 times the mass of the complete engine, and the foundation should rest on an adequate base.

Question 5

True or False;
The engine foundation is often sealed to prevent deterioration from oil or other liquids.

Answer 5

True

Question 6

True or False;
Skid-mounted equipment must be levelled and aligned when it is to be attached to the foundation.

Answer 6

True

Question 7

True or False;
Vibration isolators reduce the transfer of vibration from machine to machine and to other parts of the building.

Answer 7

True

Question 8

True or False;
The best bolts for holding the engine down to the foundation are J-anchor bolts.

Answer 8

False
Avoid J-bolts because of their low holding power and their direct contact with concrete, which may cause premature deterioration of the bolts. Piped(good) and boxed(best) are good choices.

Question 9

True or False;
Crankshaft deflections are taken to determine the rod bearing position in several locations.

Answer 9

False
Crankshaft deflection readings indicate if the crankshaft is bent. If an engine block or base is bolted down to a foundation that is crooked or warped, the base bends to conform to the foundation. This bends the crankshaft so that neither the block crankshaft bores nor the crankshaft is straight.

Question 10

True or False;
A shim is placed between the engine base and the sole plate.

Answer 10

True

Question 11

True or False;
Crankshaft deflections tell the technician if the crankshaft sits in a straight or bent position.

Answer 11

True

Question 12

True or False;
The weight of the exhaust system can rest on the engine base or on the building foundation.

Answer 12

False
Exhaust pipes and silencers should be carried by independent supports or by the engines load carrying members. There should also be flexible steel pipe between the engine exhaust outlet and the exhaust pipe. This isolates any vibration from the engine, allows for thermal expansion and keeps any weight off the engine.

Question 13

True or False;
Engine buildings require proper ventilation if the intake and air cleaner are inside the building.

Answer 13

True

Question 14

True or False;
Engine startup procedures should be followed only for new engines or engines that have been moved to a new location.

Answer 14

False
Whether an engine is being started for the first time or if the engine has been running recently, proper engine start up procedures should always be carried out by a qualified operator to ensure a safe startup.

Question 15

True or False;
The cooling system for the engine must be mounted in front of the engine with access to cooler outside air.

Answer 15

False;
The cooling system can be located almost anywhere,
except expansion tank, needs to be higher than engine.
