Press-in type 4×11kw counter-rotating axial flow fan for long distance tunnel
The Press-in type 4×11kw counter-rotating axial flow fan for long distance tunnel (hereinafter referred to as the fan) is a local fan designed for a wide range of applications. It boasts a robust structure, exceptionally low noise levels, high wind pressure, and impressive efficiency. This fan excels in maintaining stable operation within confined airflow areas while offering a broad, high-efficiency operation range. Its unique design prioritizes energy efficiency and overall effectiveness. This versatility makes it perfectly suited for ventilation needs across diverse underground mines and tunnel projects. For long-distance mine ventilation, the FBDY fan is the undeniable equipment of choice.
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.
