Product Description
The 160 kW Tunnel Construction Temporary Ventilation Fan is a high-efficiency and energy-saving ventilation device specifically designed for ventilation and air exchange in tunnel engineering construction. The product is mainly suitable for tunnel construction in high-speed rail, highways, railways, water diversion tunnels, and metal mines. It provides fresh air to the working face through forced air delivery via air ducts, while effectively removing harmful gases and dust from the tunnel.
Product Features
1. Compact structure, easy maintenance
2. High efficiency and energy saving, high air pressure and large air volume
3. Low noise
FAQ
Q: How to select the appropriate SDF fan model for tunnel construction?
A: When selecting a model, the required air volume (m³/min) and air pressure (Pa) need to be determined based on the tunnel length, cross-sectional area, and usage conditions. Standard SDF series fans can generally be used for tunnels; for tunnels with fire protection requirements, it is recommended to select models with fire-resistant features. The rated air volume of the fan should be 1.1 to 1.2 times greater than the calculated requirement, allowing for leakage and loss. Long tunnels (≥2000m) require segmented ventilation or relay air supply.
Q: How to install a 160kW temporary ventilation fan for tunnel construction?
A: A 160kW temporary ventilation fan for tunnel construction can be placed on the tunnel floor or supported on a bracket. No special equipment foundation is required; it can operate stably for a long time simply by being placed on a flat surface. If suspended installation is used, anchor bolts should be installed on the top lugs of the fan, connected with U-shaped suspension steel. The installation location should have good ventilation, avoiding bends or areas with significant elevation changes to reduce airflow resistance.
Q: What are the precautions for the operation and maintenance of a 160kW temporary ventilation fan for tunnel construction?
A: Before trial operation, check that all bolts are complete and reliable, and ensure that the impeller rotation direction matches the rotation direction mark on the casing. Start the primary fan first, then the secondary fan, and run for 20 minutes before stopping and inspecting. Regularly check the radial clearance between the impeller and the casing, ensuring it is between 0.25% and 0.4% of the impeller diameter. The maximum output power of each motor should not exceed 95% of its rated power.
