Setting Up Your Unit (continued)
The firing sequence of the diaphragm valves on the dust collector should
be set so that no two adjacent rows of cartridges fire in succession to
insure maximum cleaning and life of the filter media. This can only be
achieved when wiring the pulse timer board to the solenoid valves. If you
are experiencing a high-pressure drop across the filter bags in your dust
collector the pulse interval should be reduced.
Apply electrical power to the timer and make sure that it is cycling
completely through all rows of the unit. In some cases the timer panel
may have more “positions” than required in which case the position
selector cable needs to be attached to the proper numerical value
corresponding to the number of diaphragm valves on the unit.
If your dust collector was shipped via common carrier rather than a
contract hauler there is a possibility that the solenoid enclosure was not
shipped installed on the unit. If this is the case, there is a mounting plate
welded on the housing or the air header with the bolt pattern of the
enclosure already drilled. Bolt the enclosure and install the nylon (or
copper) tubing with the fittings provided making sure that the solenoids
are connected to their corresponding diaphragm valve.
Valves and Piping: After the unit has been installed the diaphragm
valves should be checked to make sure that the port marked “IN” is
assembled to the compressed air manifold. The “IN” connection of the
solenoid valve is connected to the diaphragm valve by means of ¼” nylon
or ¼” copper refrigeration tubing. Each nut on the compression fittings
should be checked for tightness before the compressed air manifold is
pressurized. In most cases a slip fit fitting has been used. The integrity of
the nylon tubing inside each fitting should be checked by pulling gently on
each tube. If the tube pulls out, simply push it back into the fitting until it
will not go any further. The solenoids are shipped with a plastic plug in
the discharge side of the valve. These plugs must be removed for proper
operation.
Gauges: The differential pressure gauge, mounting bracket, fittings and
tubing are usually shipped loose in a box with the dust collector. When
installing these make sure that the high-pressure port of the gauge is
connected below the tube sheet and the low-pressure port is connected
above the tube sheet on the dust collector. There are pipe couplings
welded on the side of the dust collector for these connections. After the
differential pressure gauge is permanently mounted the gauge needs to
be zeroed prior to connecting the tubing to the gauge.
