Preventive Maintenance
•
Correct problems as soon as they are discovered.
•
Inspect equipment frequently following changes in product
formulation, processing conditions or CIP regimen.
•
Always note and report any abnormal or unusual conditions.
•
Follow a regular preventive maintenance schedule. Many
factors determine the interval required for scheduled
servicing. The severity of the application and the time
between scheduled shutdowns are two of the most
significant.
When new units are first put into service, they should be
disassembled after each production run and inspected for any
obvious wear patterns. These initial inspections will establish a
process history, as well as provide a basis for establishing a
preventive maintenance schedule. Inspections should focus
primarily on tube, shaft, blade and seal components. During
normal production runs, any abnormal conditions such as
unusual noise, leakage or vibration should be noted and
corrective action taken.
Mutator Shaft Bearing
The Votator II has only one serviceable ball bearing assembly,
located in the Opposite Drive End Head of the unit. Lubrication of
this bearing while in service is done through the use of the grease
fitting located on the Opposite Drive End Head.
Install bearing with lubrication ring in line with grease fitting.
Use a suitable NLGI grade-2 bearing grease for the shaft bearing.
Do not over-lubricate. Excessively packed bearings will over heat
and fail prematurely.
Frequency of lubrication is dependant on the environment; daily if
it is in contact with water or steam, otherwise weekly lubrication
usually is sufficient.
WARNING:
Never immerse the Front Mutator Shaft
Bearing in cleaning solution or subject to steam. Clean
bearing with a dry cloth and lubricate.
Inspection of bearing should be ongoing. If looseness is detected,
replace bearing immediately. Worn out bearings cause shaft
misalignment that will cause mechanical seals and gearbox to
wear out prematurely.
Extra Heavy Duty Votator II Shaft Bearing
The shaft bearing on the Extra Heavy Duty Votator II located in
the opposite drive end head is a sealed bearing and does not
require lubrication.
