　　1、 Composition and representative significance of FBD series mining explosion-proof pressure type counter rotating axial flow local ventilation fan

　　Taking FBD No.6.3/30 × 2 fan as an example to illustrate

　　1. Environmental conditions for use

　　This product can be placed flat on the bottom of the tunnel or hung on the wall of the tunnel for use. When used on the base plate, the suction port (collector end) of the fan should not be immersed in water or cement. The gas temperature in the environment where the fan is used is -20~50 ℃, and the altitude should not exceed 1000m. The rated frequency of the power supply used is 50Hz, and the rated voltage is either 380V/660V or 660V/1140V.

　　2. Working conditions

　　This product has a dust content of no more than 200mg/m3 through gas. It should be installed in the intake airflow with a gas concentration of less than 1% underground in coal mines. When the gas concentration exceeds 1%, the power should be immediately cut off.

　　3. Impact on the environment and energy

　　This product has no pollution to the environment and belongs to high-efficiency energy-saving products.

　　4. Security

　　This product is designed reasonably and has explosion-proof certification and "MA" safety mark approval certificate. Its supporting motor also has these two certificates, making it a flameproof safety product.

　　IIFBDSeries of Explosion proof Compression Type Axial Flow Local Ventilators for Mining ApplicationsStructural characteristics and working principle

　　1. Overall structure, working principle, and working characteristics

　　This product has two impellers installed close to each other, driven by two explosion-proof motors to rotate in opposite directions. The airflow enters the first stage impeller from the collector end along the axial direction and is deflected into the second stage main engine. After being accelerated again by the second stage impeller, the airflow direction is reversed and discharged from the diffuser end along the axial direction.

　　2. Main components, operation and working principle

　　As shown in the figure, this product consists of four main components: collector, first stage host, second stage host, and diffuser. The collector is composed of an arc-shaped collector and a guide cover, and its main function is to reduce the local resistance loss of the airflow, creating good air intake conditions for the first stage main engine. The first stage main engine is composed of the first stage casing, first stage impeller, and first stage motor and other main components. The first stage casing is its load-bearing body, mainly responsible for ensuring the normal operation of the impeller and motor, while also serving as a muffler.

　　The FBD series explosion-proof press in axial flow local ventilation fan for mining is a new generation of widely used energy-saving local ventilation fan developed and produced by our company based on the summary of the existing structure and technical performance of axial flow local fans in China.

　　Tai'an Yucheng Mining Equipment Co., Ltd. mainly produces:FBDSeries mining explosion-proof pressure type counter rotating axial flow local ventilation fanWet dust removal fan Mining equipment such as extraction type counter rotating local ventilation fan, wind water linkage nozzle, balance air door, spray dust reduction device, etc.
