Product Description

Product Description

 

Our company has a complete standard product line of tunnel fans. At the same time, our company can also provide customized tunnel fan products based on the actual needs of the project. When we receive specific construction needs from customers, first of all, we will With the help of model re-selection or the use of professional software, the overall ventilation design can be carried out to minimize power consumption while meeting ventilation needs.

Tunnel fans can be divided into tunnel construction ventilation fans, tunnel jet fans and tunnel smoke exhaust fans.
 

Product Parameters

 

Tunnel construction axial flow ventilation fan

The axial flow ventilation fan for tunnel construction is a system selection and design model based on the aerodynamic model and vector optimization of our company. On the premise of ensuring ventilation needs, through reasonable fan/dryer configuration, the operating efficiency of the fan in all working conditions is optimized, and the energy saving effect of the fan purchase cost is achieved several times for the customer. All products are equipped with a frequency conversion control system as standard. The ventilator can be combined with multiple types of main blades and multiple types of guide blades to achieve tailor-made full-condition customization to meet the flow and pressure combination requirements of different altitude conditions.

Tunnel construction axial flow ventilation fans can be used to solve ventilation difficulties in over-long tunnels and tunnels with small cross-sections that cannot use thicker ventilation ducts. This series of products has an optimized multi-stage series combination structure and is suitable for ventilation of ultra-long tunnels. This product is composed of three, four and five stages respectively, all of which are put into operation to reach the highest pressure and meet the use in difficult periods. They can also be used in single stage or counter-rotation to ensure construction safety and protect the environment with low noise. It is an ideal choice for highways, Special ventilation equipment in railway and hydropower project construction.

Our company can customize axial flow fans for tunnel construction according to user requirements, and meet customer requirements by changing functions such as motor speed, hub ratio, blade material, blade number, and blade shape. The maximum air volume reaches 16000m³/min The maximum full pressure is 22000Pa

Tunnel jet fan
 

Tunnel jet fans are mainly used for longitudinal jet ventilation in traffic tunnels such as highways and railways. They use the high-speed jet airflow generated by the jet fan to push the air in the tunnel to move along the direction of the jet to achieve ventilation. However, fires in the tunnel are not possible. For the purpose of exhausting smoke, the transport medium of the jet fan is air, and the ambient temperature is between -25°C and 50°C. The dust content and other solid impurities in the medium are not more than 150mg/m3, and there is no sticky or fibrous material.

When a fire occurs in the tunnel, the tunnel jet fan can run continuously for two hours at an ambient temperature of 280°C.

Large tunnel smoke exhaust fan
 

The large smoke exhaust axial flow fan for the subway tunnel adopts advanced CFD design technology (computational fluid dynamics) and has reached the leading level among its peers in terms of wing theoretical research, fan anti-surge design, vibration and noise reduction, etc.

The large smoke exhaust axial flow fan for the subway tunnel passed the inspection of the China Fire Equipment Quality Supervision and Inspection Center and passed the national CCCF certification. Our company can change the rotation speed, number of blades, and blade installation angle according to the different technical performance parameters required for the use occasion to meet the needs of different working conditions.

The large smoke exhaust axial flow fan in the subway tunnel is equipped with an anti-surge device to prevent surge in the full performance area of the fan. During engineering installation, there is no need to install an anti-surge alarm device.

 

Underground tunnel mining dust removal fan
 

Underground tunnel mining dust removal fans can have single-stage structures and multi-stage combination structures according to the dust concentration and emission requirements at the working point. It is mainly used in tunnels, mines, subways and other places where dust is generated. It is also suitable for working conditions where it is inconvenient for ground industrial enterprises to use dust removal devices with other structural methods.

The dust removal fan for underground tunnel mining consists of two parts: an axial flow fan and a wet dust collector. The axial flow fan is composed of an air inlet flow guide tube, a main engine, a guide vane tube, and a muffler. The wet dust collector adopts a horizontal structure. In the horizontal casing with a cross-sectional shape such as rectangular or square, in the area from the air inlet to the air outlet, the rectifier grid, spray assembly, filter assembly, and dehydration assembly are arranged in sequence.

Tunnel face fan
 

The tunnel face fan is mainly used to solve the problem of insufficient ventilation at the tunnel face during tunnel mining, and is used to supplement air at the tunnel face of underground tunnels.

 

Certifications

 

Our company has passed CCC fire product compulsory certification, ISO9001 quality management system certification, CE EU certification, KA mining product safety landmark certification and other certifications.

 

Packaging & Shipping

 

1. The equipment is equipped with a number of signs such as a product nameplate, rotation direction sign, wind direction sign, grounding sign, lifting sign, safety warnings, and so on.

2. Product nameplate mainly includes the contents of the equipment: main technical parameters (flow, pressure, motor power, Revolutions Per Minute), product number, manufacturing date, and so on, which is convenient for users to check at any time.

3. Small equipment adopts the type of export wood packaging and large equipment, and the steel frame transports large cargo transportation.

4. All equipment is waterproof and rainproof.
