Question #$1$

$[5$ Points$]$

ompare the main pillars or concepts of TPM and RCM strategies? Show the main weakness and strength points of each strategy. Why we should $/$ to combine both strategies?

Which industries are more suitable for TPM$?$

What are the main steps of applying RCM$?$

Question #$2$

$[5$ Points$]$

The diagram shows frequency spectrum of a pump driven by an electric motor rotating at $1200$ rpm $.$ The data are collected at the electric motor bearing $($ S $1)$ on the side near to the coupling directly connected to a reduction gearing that drives the pump propeller at $400$ rpm $.$ If the gears have $20$ and $60$ teeth and the deep groove bearings of the motor have $9$ balls of $8$ mm diameter each, bearing inner diameter $25$ mm $,$ outer diameter $52$ mm $,$ pitch diameter of $39$ mm and width of $15$ mm ;

use the fundamentals of vibration analysis of rotary equipment to complete the following:

Frequency of $1$ X is equal tc Hz $.$

Any frequencies in zone $B$ are called $\_$

High amplitudes in region C may be due tc $\_$ or

If the recorded vibration at $2$ X is in both axial and radial directions this is then caused by

The high peaks at zone $D$ may indicate

The crossing at region E indicates defective $q,$

To check for motor rotor faults, zoomed frequency spectrum near frequency should be checked for

To make sure of gear meshing faults, zoomed frequency spectrum nea frequency should be checked for

When a transducer S $2$ is placed on the pump shaft, it is normal to detect amplitude peaks at and Hz representing and
