Do you know what the heart of a pulse-jet baghouse system is?
A pulse valve is the key part in a pulse-jet cleaning system. Pulse valves are considered the heart of pulse-jet dust collectors and are the only moving part of these systems. It is vital that these valves are functioning correctly by producing a good, solid pulse.
What does a good pulse sound like?
A pulse valve should give off a loud sound similar to that of a gunshot. The valve should be exerting compressed air in the range of 80-90 psi in order to effectively clean the filters of excess dust in the collector. The pulse should also be short, as this reflects the released compressed air.
Locating a misfiring valve in a larger system can be tricky as there may be hundreds of pulse valves.
The trick to finding the problematic valve is very simple. Each pulse valve has a breather hole located at the top of the valve. The compressed air is released from the breather hole of the valve. If the valve is misfiring then it will not be exerting a sufficient amount of pressure from the breather.
Cover all the breathers with tape and check them the next day. If any breathers still have the tape intact over the hole, this indicates that the valve is not operating correctly.
If the pulse valve is indeed misfiring then the part may need to be rebuilt or replaced. Keeping all of the valves firing at the appropriate psi will reward you with optimum performance from your pulse-jet dust collector.
