MAINTENANCE
Every 1000 working hours the following parts should be checked:
1 Filter bag – for wear.
2 Rubber seals – for tears and over-compression.
3 Shaker mechanism (see fig. 12) with particular attention to:
tightness of mounting bolts.
play in eccentric.
splits in diaphragm.
broken locators on shaker bar.
torn shaker bar support strap(s).
eccentric bearing: check for lubrication; any absence may lead to
excessive heat being generated during operation.
Any defective parts should be replaced.
Annually
1 Flameproof maintenance – It is important that all flameproof enclosures,
motors and cable glands are inspected for corrosion and tightness on an
annual basis.
In particularly aggressive environments, this period should be more
frequent.
2 Antistatic earthing (if fitted) – Check collector earthing continuity.
