DMF-Y-76S Immersion 3'' Inch Dust Collector Pulse Jet Valve
About Diaphragm:
The pulse valve diaphragm is divided into two, gas chamer (Front & Back), when switching compressed air, compressed air through the throttle orifice into the gas chamber after at this time of the gas chamber pressure will diaphragm components.
Close to the valve outlets, pulse valve is in " closed" status.
Pulse injection control instrument signal that the pulse valve bit back, after the gas room put stomatal open, and the gas chamber pressure loss after quickly, diaphragm components moved the compressed air. A valve lose export injection, pulse valve in the " open " status.
The diaphragm is damaged, after long-term work, the diaphragm is prone to fatigue, oxidation, etc., resulting in the appearance of the pressure relief port long-term gas, pulse valve does not work, the treatment is to replace the diaphragm

Pulse jet bag filter with dust collector valve working principle:
The dust-containing gas enters the middle of the dust collector, and the lower tank passes through the dust-removing bag to enter the upper casing due to various effects of the dust-removing bag. The dust gas is separated, the dust is sucked on the dust bag, and the gas passes through the dust bag and enters the upper tank from the venturi and is discharged from the air outlet.
During the process of purifying the dust-containing gas through the dust bag, as the time increases, more and more dust accumulates on the dust bag, so that the resistance of the bag is gradually increased, and the amount of gas passing through the bag is gradually reduced, in order to remove dust. The device can work normally, so the resistance should be controlled within a limited range (generally >120-150 mm water column). In this way, when the resistance rises to a limited range, the pulse controller will issue an instruction to trigger each DMF-Y-76S electromagnetic pulse valve in sequence to open DMF-Y-76S pulse solenoid valve. The compressed air in the air bag is sprayed into the corresponding dust bag by the venturi tube through the holes of the spray pipe, and the dust bag is rapidly expanded under the reverse action of the air flow, so that the dust accumulated on the surface of the dust bag is detached, and the dust bag is restored to the initial stage. Filter status. The dust that has been cleared falls into the ash hopper and is discharged from the body through the ash discharge system. Since the dust accumulated on the dust bag is regularly removed, the purified gas passes normally to ensure the normal operation of the dust collector.
