Special blower for pneumatic conveying of sewage treatment

(' H' >First of all, the difference in air volume: the fan spindle speed of the connected Roots blower can be adjusted at will according to the ratio of the motor and the fan pulley, and the manufacturer can arbitrarily combine it, so the flow range and pressure range of the connected Roots blower on the market are wide. However, the direct-connected Roots blower can only have a fixed speed. The fan main shaft speed is equal to the motor speed. The same type of fan and the same level of motor flow can only be fixed. Secondly, the difference in application: Ironmaking and other working conditions with high ambient temperatures Under normal circumstances, direct coupling is generally used. The belt is not resistant to high temperatures and is easy to slip and break. Furthermore, under high static electricity conditions, ordinary belts cannot be used. Beryllium bronze belts or direct couplings can be used. Finally, direct coupling and belts have their own advantages. Don’t worry too much about the advantages and disadvantages of the two. There are no special requirements. Generally, the belt is used, which is easy to maintain. When it is difficult to choose and there are no special requirements, it can be based on the size of the base.
