1
|
As the name suggest, it is the
maintenance as a routine work i.e. daily work so routine maintenance is a overall
daily maintenance of the machine.
|
As the little name suggest, this
maintenance is essential in case of failure of machine activity/breakdown in
operation of machinery.

|
In daily routine work, current,
voltage, power, may be periodically observed or noted and a record may be
kept for certain purpose.
|
Electrical faults may be due to short
circuit, overheating, failure of insulation, earth fault etc.
|
|
3
|
Check the switches, starters,
indicators neatly before starting machine.
|
Failure of machine may take place due
to serious electrical or mechanical faults.
|

|
For mechanical stability of the
machine, see that the working is noiseless, vibration less. If not take it
for necessary corrections/ repairs/ maintenance.
|
Mechanical faults may be due to
damages of parts, bearing jamming, failure of cooling system, clogging of
ventilating ducts; much more deviation in the air-gaps, between rotating and
static parts, loosing of stampings of iron cores etc.

|
After the stoppage of the Machine is
to be nearly cleaned to remove dirt, dust, near wastages, scraps. For
cleaning, a soft cloth, broom, vacuum cleaner, blower may be used.
|
After mechanical faults arise the
machine is completely shut down and immediately to be taken for Inspection,
Fault finding and repairs so that continuity of working can be brought back
is a shorter period to avoid further shutdowns.

|
Earth connections must be checked to
avoid shocks from leakage currents. Also while machine is working thermal
conditions must be ascertained by checking temperature. Excessive temperature
may damage the insulation.
|
To avoid mechanical faults check that
Insulation is in tack. (It not make necessary replacement), check uniform air
gaps between static and rotating gars, tighten loose bolts, parts, nuts,
terminals etc. Air circulation system should be repaired.
