Pre-cleaner Inlet (Arr. D)
Under certain operating conditions, a deposit of dust will occur at the border
line of the dry and wet zones in the pre-cleaner inlet. The removal of this deposit
must become a part of regular maintenance. The frequency of removal can be
established only by periodic inspections when the RotoClone is first put in
operation. The deposit should never be allowed to obstruct more than one quarter
of the area of the pre-cleaner inlet.
A door is provided at the pre-cleaner inlet to remove this accumulation. Be
sure spray nozzle is not damaged or clogged and that nozzle orifice is vertical.
Gasket seal should be cleaned before closing inlet door.
11.6
RotoClone Impeller
Inspect the RotoClone impeller periodically for accumulations of foreign
material or obstructions in blade hooks. The blade hooks formed by the leading
edge of the impeller blades convey the collected dust and water out of the
airstream. A buildup of dust within these hooks may be sufficient to cause
pronounced vibration or dust and water entrainment. Such accumulations should
be removed either by flushing with high velocity water jet or scraping with long
screw driver through access door in back of RotoClone housing and from front side
of impeller.
Flat spray of flushing nozzle located at impeller (7 o’clock position, viewed
from the inlet) should be parallel to blade edges. Check this spray with water on
periodically to ensure proper positioning and spray pattern.
Certain accumulations in RotoClone impeller cause no difficulty and can be
disregarded. They include minor deposits on back of impeller blades, slight coating
or small deposits on front side of blades, and slight deposits in blade hooks that do
not obstruct flow of dust and water.
11.7
Drains
Keep all drains clean. If necessary flush out periodically. A plugged drain can
cause damage to the impeller. Inspect grating in bottom of the Arr. D RotoClone
hopper periodically and remove any accumulation.
