The SDF-I II III IV series counter-rotating high-pressure axial flow tunnel ventilation fans are mainly used in high-speed rail, expressways, railways, subways, water diversion tunnels, chemical storage warehouses, municipal cable tunnels, metal mine tunnels, and other fields. The temperature of the conveyed medium shall not exceed 60°C, the humidity shall not exceed 95±3% (at 25°C), and the medium shall be non-corrosive.
Product Advantages
-
Compact structure, safe to use
This series of fans consists of a collector, a primary fan, a secondary fan, a motor, a bipolar silencer, etc. The casing and structure are welded from thick steel plates. The impeller is made of aluminum alloy through high-pressure precision casting, subjected to X-ray flaw detection, and carefully selected high-quality blades ensure the raw materials are more precise and sturdy. The fan adopts a direct connection between the motor and the impeller, ensuring reliable transmission. The overall structure is simple and compact, sturdy and durable, safe to use, and easy to maintain.
-
Three-dimensional flow aerodynamics
The impeller is designed and manufactured using three-dimensional flow aerodynamic theory, variable-sweep combined orthogonal blades, and many other high-tech technologies such as aircraft turbo engine blades.
-
High efficiency, good performance
The whole machine features compact structure, low noise, high efficiency, good aerodynamic performance, high wind pressure, stable operation in the working area, and a wide range of high-efficiency applications. According to the length of the tunnel excavation face and different ventilation requirements of the roadway, it can be used as a whole machine or in stages, thereby reducing energy consumption and saving energy. It is an ideal device for medium and long-distance local ventilation in tunnel excavation.
-
Electric system
It adopts a controller specially designed for engineering machinery, with better dust resistance and water resistance, and an extremely low failure rate. Through integration with self-developed cloud platform technology, it can perform remote fault diagnosis, maintenance reminders, and other functions for the equipment.
-
Ultra-quiet
The silencer adopts an externally wrapped composite noise reduction device. All main units are equipped with silencers, giving the whole machine ultra-quiet characteristics.
