6.2 General dismantling set up
Step 1
NOTE
A rigorously implemented preventative maintenance program will significantly reduce repair costs over the life of the Alfa Laval
Gamajet. The foundation of such a program is regularly scheduled inspections to discover and replace worn or damaged parts
before they can cause the failure of other, more costly, components. The inspection intervals required will depend on the
severity of the application, but a complete internal inspection at 100 hours of operation is recommended initially.
Step 2
STORAGE
The Alfa Laval Gamajet should be washed out with clean water after each use to remove any foreign material or soft
substances left in the machine that may harden during storage and cause the Alfa Laval Gamajet to seize or lock up. A clean
water rinse through the Alfa Laval Gamajet will also wash out any residues of chemical cleaners or recirculated wash water that
could adversely affect the seals and O-rings during prolonged contact in storage. The best position to store the Alfa Laval
Gamajet is to stand it up with the inlet connection facing down.
Step 3
EXTERNAL INSPECTION INTERVALS
Before every shift, the Stator (9) and the Nozzles (7) should be inspected for debris. Examine the Stator by loosening the Collar
Set Screw (45) and removing the main section of the machine from the Collar (8).
Note:
One does not have to remove the Inlet
Collar (8) from the supply pipe when performing this check; simply, loosen the set screw (45) and unthread the body from the
(8). Look into each Nozzle for signs of debris or build-up. Also, the vent holes on either side of the (26) should be checked for
blockage. Use a fine wire or compressed air to clear them, if necessary.
Step 4
INTERNAL INSPECTION INTERVALS
An interval of 100 hours is recommended initially. If all of the components are found to be in acceptable condition after the first
100 hours, the Alfa Laval Gamajet may then be inspected and routine preventive maintenance should be performed every 300
to 500 hours of operation, depending on the severity of use.
Step 5
TIPS
All the Bearings, Bushings, Seals and O-rings are wear parts. Ideally, they should all be replaced, as a group, every 300 to 500
hours of operation, depending on the severity of use. If just one Bearing or Seal is worn or damaged, replace both it and its
mate, not just the worn or damaged part.
