Pipe fan selection control parameters for the air volume, total pressure, efficiency, noise, motor power and so on. Depending on the physical and chemical properties of the gas being transported, fans of different uses are selected.
Features
1. Pipe fan selection control parameters for the air volume, total pressure, efficiency, noise, motor power and so on.
2. According to the physical and chemical properties of the gas being transported, select the fan for different purposes. Such as the delivery of clean air, should choose a general fan; transport flammable and explosive gases, explosion-proof fan should be selected; corrosive gas transmission, corrosion-resistant fan should be used.
3. Ventilator selection, should consider the leakage of piping system losses, calculation errors, and the actual fan fan, the negative pressure deviation, the general use of air flow 1.05 ~ 1.1, wind pressure of 1.10 to 1.15 safety factor. However, it is neither too large nor too large to prevent the fan from operating in an area of low efficiency for a long time.
4. Pay attention to the matching characteristics of the pipe network resistance characteristics and fan characteristics. In order for the ventilator to operate stably, the ventilator should be operated near its maximum efficiency point. The operating point of the ventilator is located on the right side of the full pressure peak point in the performance curve (ie, on the gales side and generally at 80% of the full pressure peak) ).
5. For ventilation systems with muffler requirements, fans with high efficiency and low impeller circumferential speed should be selected first and operate near the highest efficiency point. Should also be based on the ventilation system noise and vibration propagation, take the appropriate noise reduction and damping measures.
6. Pipe fan is through the blade shape changes, the air flow into the fan, the existing part of the axial flow, but also produce part of the centrifugal effect, so its performance is between the axial flow fan and Centrifugal Fan.
7. Piping ventilator can provide medium pressure and moderate air flow, ventilation system used in high-rise civil buildings are more appropriate.
Installation points
1) The natural frequency of the basic device shall not be greater than 1/3 of the motor and fan speed;
2) The difference between the vibration speed when the ventilator is running and the vibration speed when the ventilator is stationary should be more than 3 times.
2. Ventilator inlet and outlet connections between the duct should be set flexible joints. Into the air duct, air duct and other devices should be a separate support, and by the foundation or other components of the firm support firm, the chassis should not bear the weight of other parts.
3. Fan installed in the building components, should take measures to isolate vibration.
4. Fan installation can refer to the following national building standard design atlas.
5. Pipe fan can be installed in the straight pipe, with easy to take over, taking up the advantages of smaller space.
