Double Diaphragm Pulse Valve , Pulse Jet Solenoid Valve 24VDC / 110VAC SBFEC Type
During installation and commissioning
1 . The valves cannot all be opened, but the leading part does act.
2 . Some valves do not work, but the others are normal.
3 . The valves cannot all be closed. There is leakage. There is no way to establish a gas dome.
4 . Some valves cannot be closed. There is leakage.
5 . A valve closing is slowly.
1 . Check the gas dome pressure to see if it is too low.
2 . Check the valve coil connection and coil
3 ( 1 ) . Y-valve. Some valves for the same gas dome are leaking, thus causing leakage for all the valves.
3 ( 2 ) . Z-valve. The valve inlet and blowing muzzle are installed backwards.
4 . There is some dirt or debris on the membrane, ii is blocking the moving iron core.
5 . The membrane orifice is blocked.
1 . Check the leakage
2 . Replace the accessories
3 ( 1 ) . Check the leakage
3 ( 2 ) . Re-install
4 . Clean the membrane and check that the membrane is complete. Check the moving iron core and air lock.
5 . Dredge the membrane orifice
During use period
1 . Some valves are leaking. The membrane cannot close tightly and the valve is always open a
2 . Coil is hot and burned out.
3 . Voltage exists but the valve does not operate.
4 . Ambient temperature is below -20℃. The valve is leaking and cannot open.
1 . There is some dirt or debris on the membrane, the leading part is damaged. Moving iron core is blocked.
2 . It has been turned on for too long.
3 . Membrane is damaged and the orifice is blocked.
4 . Ambient temperature is too low and here is frost in the valve.
1 . Clean the membrane and check that the membrane piece is complete. Check the moving iron core and the air lock. Replace the accessories if necessary.
2 . Check the working condition of the control system.
3 . Replace the accessories in time.
4 . Pay attention to insulation and maintaining proper temperatures.
Electromagnetic valve ( Also called diaphragm valve ) is the” switch “for compressed air in the dust clean blowing system of the pulse bag filter . Controlled by the output signals of the pulse jet control device , it makes dust clean to the filter bags cell by cell to keep the resistance of thebaghouse within the set range and thus guarantee the processing functions and the dust collecting efficiency of the baghouse .
Z type electromagnetic pulse valves is a right angle valve , with the 90 degree , angle between the inlet and outlet , which is suitable for the installation connection between the gas dome and the baghouse blow tube provide good air flow and dust clean pulses satisfying the requirements .
The electromagnetic pulse diaphragm valve is composed of two gas cells . When the compressed air is connected , it comes into the back bags cell though the orifice , the pressure in the back gas cell pushes the diaphragm against the outlet of the valve and the electromagnetic valve stays in the “closed” condition .
When the electromagnetic pulse valve returns to its original position .
The air escape of the back gas cell closes and the pressure in the back gas cell cellrises , which pushes the diaphragm closely again .
