Performance and testing methods of mining air ducts

Mining air duct refers to the ventilation equipment used in industrial production sites such as mines, coal mines, and building materials factories, mainly used to discharge harmful gases and maintain a dry and clean environment as a tool. It is usually composed of motors, blowers, ducts, exhaust fans, fans, and other components, and is widely used in drilling, blasting, coal mining and other operations.
During the operation of mining air ducts, the accumulation of dust, grease and other substances often leads to abnormal operation of the blower. If not cleaned in time, it will seriously affect production efficiency and safety. Therefore, cleaning the mining air duct is very important. Below are the specific methods for cleaning the mining air duct.
1. Turn off the power
Before cleaning, the power supply of the air duct must be turned off first to avoid accidents. At the same time, the equipment and ventilation ducts connected to the air duct should also be isolated to ensure that cleaning does not affect them.
2. Disassemble the blower
Firstly, it is necessary to disassemble the blower, remove the gear sleeve and impeller, and clean the inner chamber, vortex chamber, and impeller. Use specialized tools to clean dust, scales, and oil stains inside the air duct, and be particularly careful not to use any cleaning agents containing acidic substances.
3. Clean the exhaust fan
The exhaust fan is the key to cleaning the mining air duct, as it is the last guarantee of the mining air duct and directly affects the air quality at the outlet. When cleaning the exhaust fan, it is necessary to remove the cover plate of the exhaust fan and remove the screws on the cover shell. Then, thoroughly clean the vortex chamber, impeller, and front lining plate.
4. Clean the dust
During long-term use, mining air ducts will produce a large amount of dust and oil stains, which can seriously block the inlet and outlet of the blower. When cleaning, be sure to completely clean the dust inside and outside the air duct, including the fan, air outlet, and other areas.
5. Install the blower
After cleaning the air duct, it is necessary to reinstall the blower to ensure the correct installation position and secure sealing of all components. Adjusting the angle of the fan blades can change the airflow and speed of the fan. In addition, all accessories should be installed on the original equipment and the air duct should be tested to ensure normal operation and correct installation.
In short, cleaning mining air ducts is an important measure to ensure production, improve efficiency, and ensure safety. When cleaning, it is necessary to strictly follow the procedures, comply with relevant safety operating norms, ensure that the cleaning effect meets the standards, and ensure the normal operation and production safety of the equipment.
