Malfunctioning dust collectors can greatly affect the operations of your business. They can trigger unexpected shut-downs and expensive downtimes, with the produced airborne dust threatening the safety and health of your workers. When the dust collectors are ineffectually operating, they raise your utility bills since leaking valves make the fans and compressed air to work overtime to stay in the face with the plugged bags. You can always contact us for dust extractor filter bags when you discover problems with your existing plugged bags

Practical Tips to Efficiently Troubleshoot Major Dust Collector Issues - puratex

Filters Not Cleaning Properly

When the filters aren’t cleaning appropriately, they can make the pressure drop to go higher, which will ultimately lower the airflow within the dust pick-up points, triggering higher energy consumptions. Check out these tricks to troubleshoot filters that are proving hard to clean. You can as well contact us for dust extractor filter bags at any time.

●Have a look at the hoppers — hoppers are usually found in the lower end of the dust collector and should be the main part to check when troubleshooting issues with filters that are cleaning. If there is no rotary valve in your dust collector’s hopper, empty the hoppers regularly. Also, ensure the valve is properly discharging.

●Ensure there is no moisture in the dust collectors — ensure there is no excess moisture in the unit’s compressed air stream. You can use compressed air dryers to remove moisture. As well, you should also check for oil leaks.

●Check the timer operation — while evaluating the timer, check the LED lights and pay attention to the pulses. You may have to check the timer manually to familiarize yourself with the timer’s pulse duration and cleaning frequency.

●Check the solenoid valves — when malfunctioning, the solenoid valves will make the pulse valves to fail.

Dust Collector Operating at Lower Volume

When dust collectors run at lower volumes, they won’t pick enough dust, which will ultimately cost your plant more money and time. You can troubleshoot this problem in these easy steps.

●Get the filter bags cleaned — when the plugged filter bags aren’t properly cleaned, they trigger high-pressure drop, which causes lower air volume. Clean the filter bags in an off-line mode for about fifteen minutes with the fun turned off. If after cleaning the filter bags and turning on the dust collector, the pressure drop remains high, replace the filters.

●Check the performance of the exhaust fan — when the belts slip or the impeller is poorly conditioned, the exhaust fan will develop issues, which will need to be addressed immediately.

●Check the inlet ducts — ensure the inlet ducts are working proficiently by checking and correcting any improper fittings or connections.

Dust Collector Working at Higher Volume

When the dust collectors operate at excessively high volumes, picking more products, it simply means they are overworking, which can greatly affect their lifespan. These are the best ways to troubleshoot overworking dust collectors.

●Fine-tune the speed of the fan — an overworking dust collector signifies a fan running at an extremely high speed. Check and adjust the fan speed to handle the issue of dust overworking.

●Secure the inlet ducts properly — if the ducts are bigger than they should be, they will reduce the dust collector’s static loss hence causing higher airflow. Carefully check the ductwork static pressure and try modifying the fan to achieve perfect pickup volumes and ductwork velocities.

●Inspect the filter bags — missing or malfunctioning filter bags will lower the system static loss and raise the conveying air volumes. Consider replacing the filter bags to save yourself the hassle and minimize such issues.

Dust Collector Experiencing Higher Dust Leakage

This is another problem common with dust collectors that should be addressed immediately. Here are simple ways to address the issue amicably.

●Check the filter bags thoroughly — inspect the air plenum found on the top end of tube sheets for leaks and troubleshoot it at once. In the event of extreme dust leakage, try checking the filter bags to find out if they are properly installed. Ensure to reinstall the filters if you realize that they are improperly installed. Confirm there is no dust on the tube sheet as it may as well be a cause of such issues.

●Check the air plenum for leaks — conduct thorough visual inspections of the clean-air-plenum to find out if there are any dust leaks. If after checking it you don’t know where the leakage is coming from, check the fluorescent powders found under the backlight. Try introducing the fluorescent powder to the dust collector inlet and run it to efficiently clean the system off. Turn off the fan and then try inspecting the clean air-plenum using the backlight. When you do so, the leak point will often glow the bright fluorescent color. If you cannot do it by yourself, you should consider seeking the services of a professional.
