4×4kw mining flame-proof counter-rotating axial flow ventilation fan
4×4kw mining flame-proof counter-rotating axial flow ventilation fan is a type of fan specifically designed for use in hazardous environments, such as mines and industrial settings where there is a risk of explosion. These fans are built to withstand the harsh conditions of these environments and provide reliable ventilation.
Structures
1. Current collector 2. Panel-type muffler front tube 3. First-level panel-type muffler host 4. First-level impeller 5. Second-level impeller
6. Secondary panel-type muffler main engine 7. Third-stage impeller 8. Guide vane tube 9. Panel-type muffler diffuser tube
This fan prioritizes a comfortable working environment with its unique panel-type muffler structure. The entire outer flow channel utilizes flexible materials, effectively forming a muffler that significantly reduces the noise radiated by high-speed airflow. This innovative design translates to noticeably quieter operation during use.
The fan’s structure further optimizes performance and efficiency. The outer diameters of crucial components – the fan rectifier cap, muffler core, motor base, and rear muffler cone – are meticulously designed to maintain complete consistency. This ensures an uninterrupted and smooth flow channel throughout the fan body. As a result, the fan achieves an improved pressure coefficient, leading to a stronger wind delivery distance.
The panel-type muffler structure offers another key benefit: easy maintenance. The muffler cotton utilizes a fixed end with a movable installation form. This allows for effortless replacement in case of wear or tear, ensuring the fan maintains its optimal muffling effect throughout its extended service life.
