BAGHOUSE: PRE-START UP
BAGHOUSE
All joints and connections to the baghouse should be made air tight. Visual checks should be made on welds, flanged
connections and gaskets for any damage that could have occurred in transit, unloading, or erection. All hatches, access
doors, and clean outs should be bolted tight, and checked to insure a positive seal.
BAGS
Bags should be checked to be sure that all are in place, and are sealed against tubesheet.
SCREW CONVEYORS/AIRLOCK
Reference Wm. Meyer manual and drawing.
Inspect bearings and gear reducers for proper lubrication. Check the rotor for clockwise rotation (facing belt/chain
guard)
Make certain that no foreign objects, such as tools, have fallen into the conveyors or airlock during installation.
JET PULSE
The pressure gauge on the header pipe should read between 80 and 95 PSIG. Initiate the pulse cycle. One
diaphragm valve will open at a time to pulse one row of bags. The pressure in the header pipe must build back up too 80-
95 PSIG before the next pulse. If the pressure is too low between pulses, adjust the timer so that there is more time
between pulses.
Check that each diaphragm valve closes after every pulse and be sure there are no leaks in any of the piping.
AIR COMPRESSOR
Reference Ingersall-Rand manual and drawing.
Check crankcase oil level, compressor rotation, and prime condensate trap. Test pressure regulator and oil level
switch.
