When conducting maintenance on a bag dust collector, there are several important precautions to keep in mind. First and foremost, always ensure the power supply is turned off before starting any maintenance work. The operator should carry the key to the control panel and clearly display a warning sign indicating that the equipment is under repair and must not be operated.
All transmission components like rapping devices, star unloaders, and exhaust fans—especially parts like couplings, belts, and linkage wheels—should be equipped with proper guards. These guards will help prevent injuries caused by loose bolts, flying belts, or chain breakage.
During routine checks or operational tasks, operators must be cautious to avoid clothing getting caught in moving parts. If personnel need to enter the ash hopper or work inside the baghouse, they must wear appropriate personal protective equipment (PPE) to guard against dust inhalation or eye injury.
For dust collectors handling combustible or explosive dust, regular cleaning of dust deposits is essential to prevent fires or explosions. Under no circumstances should electric welding be performed while the system is in operation. If pipe or shell repairs are necessary, it’s best to use gas welding instead.
In summer, when servicing positive-pressure fiberglass bag filters dealing with high-temperature gases, take precautions to avoid heatstroke when entering the gas distribution chamber to replace or suspend filter bags.
When working with dust collectors that handle harmful or toxic gases, it’s critical to replace the system gas with clean air to prevent oxygen deprivation or poisoning. Always follow safety protocols carefully.
After completing maintenance, thoroughly inspect the equipment to ensure no tools or foreign objects have been left behind. Ensure all protective covers are securely installed before restarting the system.
Before opening or shutting down any part of the dust collection system, make sure to communicate with all relevant positions and follow the prescribed startup or shutdown sequence outlined in the operating manual.
For major overhauls of bag filters, specific attention should be given to the vacuum hood. Key maintenance areas include:
a. Ensuring the mobile dust cover is positioned correctly.
b. Inspecting for deformation or damage.
c. Checking connections to pipelines for integrity.
d. Removing accumulated dust and ensuring thorough cleaning.
e. If a water cooling system is installed, monitor displacement, drainage temperature, and look for leaks to maintain optimal cooling performance.

Emergency downlights are lighting fixtures that are designed to provide illumination in the event of a power outage or emergency situation. These lights typically feature a battery backup system that allows them to continue functioning even when the main power source is unavailable.
Emergency downlights are commonly installed in commercial and industrial buildings, as well as in residential settings where reliable emergency lighting is essential. They are often mounted on ceilings or walls and are available in a variety of designs to suit different aesthetic preferences.
These lights are typically equipped with high-quality LED bulbs that provide bright and efficient illumination. Some models may also feature additional features such as motion sensors or adjustable brightness settings.
Overall, emergency downlights are an essential safety feature in any building, providing reliable lighting during emergencies to help occupants safely navigate and evacuate the premises.
