(A) filter and duct leakage outward or inward leakage 1. gray dust of gold ducts and duct fans wear before and after perforation due to import filter design wind speed at around 6 ~ 10m / s, the fan wind speed at 14m / s or so, easy to wear and tear duct perforation. If leakage or outward leakage gray, slight leakage can cure serious need to replace the duct, the duct 2. gold dust and dust collector interface crack leak site wind speed and pressure when the system starts to gray dust inward changes, resulting in the duct has been sucked deflated phenomenon, over time, these areas will be cracking and leaking gray, double-check the site, the materials used to seal minor cracks and serious need to replace the duct or welding. Check the filter door is closed, connecting screws are loose. (B) the pulse jet dust collector not fault 1. No compressed air can not hear the sound of air blowing dust collectors at runtime concerns electromagnetic valve core action, "da da" sound, indicating that there is no dust compressed air supply, low air pressure display should retain compressed air valve check whether the recovery, if not, the explanation did not send compressed air power plant, maintenance repairman report. 2. All the injection valve can not open if there is no point solenoid valve core action, "da da" sound, indicating that the electrical control failure, there is no command to open the solenoid valve, electrical maintenance reports. 3. The portion of the injection valve can not be opened if only a few of the solenoid valve can not be opened, then the internal solenoid valve is damaged, the most common being damage to the injection valve return spring core operation, maintenance workers report processing. (C) dust bag pressure inspection "u" shaped pressure meter, generally should be about 800pa, if it reaches 1200pa above described bag blockage, there may be a bag to use for too long, there may be a lack of compression pulse reverse blowing system air or damaged. Under (d) the amount of ash dust precipitator ash exception checking whether the usually fairly, if too small, it can be determined under the precipitator ash exception. Ash fall under 1. Check whether the rotation. 2. Check push gray spiral rotation is normal. 3. Transparent dust precipitator tribes within the window to check whether it is normal to observe Ash, if there is dust adsorbed on the bag. 4. If the dust inside fouling serious, but do not fall down, there may be soot wetter need further cleaning clogged.
