　　Daily operation of explosion-proof centrifugal fans

　　Explosion-proof centrifugal fans are fans that can be used in flammable and explosive factories, which do not produce electric sparks during operation. Explosion-proof motors are mainly used in industries such as coal mining, oil and gas, and petrochemicals. In addition, they are widely used in textiles, metallurgy, urban natural gas, transportation, grain and oil processing, papermaking, pharmaceuticals, and other sectors.

　　As the main power equipment, explosion-proof motors and explosion-proof fans are usually used to drive pumps, fans, compressors, and other transmission machinery. With the development of science and technology and production, there are more and more places with explosion hazards. For example, in the past, traditional pressing technology was used to produce edible oil, and our country began to introduce advanced foreign oil extraction technology, which requires the use of chemical solvents containing hexane.

　　Hexane is flammable and explosive; therefore, oil extraction workshops have become dangerous places for explosions, requiring the use of explosion-proof motors and other explosion-proof electrical products. Moreover, in recent years, the rapid development of roads in our country has led to a large number of fuel filling stations, which also provides a new market for explosion-proof fans. According to the principle of motors, they can be divided into explosion-proof motors and explosion-proof DC motors.

　　According to the place of use, they can be divided into underground explosion-proof motors for coal mines and explosion-proof motors for factories. According to the explosion-proof principle, they can be divided into explosion-proof motors, increased safety motors, positive voltage motors, spark-free motors, dust-proof explosion-proof motors, etc. According to the matching main engine, they can be divided into explosion-proof motors for coal mine conveyors, explosion-proof motors for coal mine winches, explosion-proof motors for rock loading machines, explosion-proof motors for local ventilation in coal mines, explosion-proof motors for valves, explosion-proof motors for fans, explosion-proof motors for ships, explosion-proof motors for lifting metallurgy, and increased safety brushless excitation synchronous motors.

　　In addition, they can also be classified according to rated voltage, efficiency, and other technical indicators, such as high-voltage explosion-proof motors, high-efficiency explosion-proof motors, high slip rate explosion-proof motors, and high starting torque explosion-proof motors. Fiberglass fans are widely used in general factories and various buildings for ventilation and explosion-proof purposes, especially in modern building designs for civil buildings, power, electroplating, pharmaceuticals, oil, chemicals, metallurgy, warehouses, etc., where strong ventilation and the discharge of corrosive gases are required. The mechanical strength of the body is high, and it is lightweight. The mechanical strength of fiberglass materials is far superior to that of plastic materials, comparable to steel, with a weight of only about one-third of steel. The efficiency of fiberglass centrifugal fans is similar to that of steel fans, with stable operation and low noise.

　　Exhaust gas treatment fanCharacteristics:

　　1. It has dual functions of blowing and suction, and can either suck air or blow air.

　　2. Low oil or oil-free operation, outputting clean air.

　　3. Compared to centrifugal fans and medium-pressure fans, its pressure is much higher, often several times that of centrifugal fans.

　　4. The pump body is integrally die-cast, using shock-absorbing mounting feet, so the installation foundation requirements are very low, and it can even operate normally, which is very convenient, saving installation costs and time.

　　5. Compared to similar fans, its operating noise is low, thus introducing ultra-quiet high-pressure fans.

　　6. Maintenance-free use, with wear only on two bearings, requiring basically no maintenance during the warranty period.

　　7. The mechanical wear of high-pressure fans is very small because there are no other mechanical contact parts except for the bearings, so the service life is naturally long, and as long as it is used normally, there is no problem for 3 to 5 years.

　　8. Simple installation and easy to use!
