Requirements for medium, temperature and operating conditions of centrifugal fans for plastics machinery
In the process of operation of plastic machinery centrifugal fan, it is mainly through the development and careful design and manufacture of a new generation of anticorrosive ventilation equipment. The main feature of the fan is the impeller when it is used. Using glass fiber reinforced polypropylene as raw material, the blade and air inlet are produced by injection molding, which greatly improves the mechanical strength of the impeller and has the advantages of smooth operation and low noise.
The impeller rear disc of plastic machinery centrifugal fan is added impeller, so that the gap between the shaft diameter of fan and the center hole of the shell can be produced in the process of operation, and the poisonous and harmful corrosive gas will not leak out during the operation. Fill in the domestic blank, is the current chemical, pharmaceutical, rare earth, smelting, electroplating and other industries corrosion-resistant ventilation equipment.
Plastic machinery centrifugal fan suitable for gas medium, temperature, and operating conditions
1. The fan is made of polypropylene raw material, suitable gas medium must meet the corrosion resistance requirements of polypropylene.
2. The auxiliary gas temperature must be ≤ 80 ℃, and the dust content of the gas must be less than 100 mg / m3. The auxiliary gas should be free of viscous matter and particulate matter.http://jnblower.com/
