By delivering these short bursts of compressed air, the pulse jet valve ensures the system operates smoothly and maintains efficiency by cleaning the filters regularly.
1. Compressed Air Supply: The pulse jet solenoid valve is connected to a compressed air reservoir, usually a large valve tank that stores compressed air at a set pressure.
2. Diaphragm Mechanism: Inside the pulse jet valve, there is a diaphragm that controls the flow of compressed air. When the diaphragm is closed, it blocks the air from flowing through.
3. Electromagnetic Solenoid Activation: The valve is operated by an electromagnetic solenoid. When the solenoid is energized, it creates a magnetic field that moves a plunger or releases a small pilot valve. This reduces the pressure on one side of the diaphragm.
4. Diaphragm Opens: With the imbalance in pressure, the diaphragm is lifted, allowing a sudden release of compressed air. This air travels through a pipe and is directed into the filter bag or cartridge.
5. Pulse of Air: The compressed air bursts into the filter bags or cartridges, momentarily expanding them. This pulse shakes off the dust particles, which fall into the hopper below the filter.
6. Diaphragm Closes: Once the solenoid is de-energized, the pilot valve resets, and the pressure equalizes, causing the diaphragm to close and stop the airflow.
7. Repeat Cycle: The pulse jet valve operates in rapid cycles, typically controlled by a timer , which detects when the filters need to be cleaned.
