W5-48 high temperature fan performance fan performance and selection generally refers to gas transport performance in specified state. Specifies the state of the fans is: state of the atmosphere Pa = 101325Pa, medium flue gas temperature t = 400 ℃, gas density ρ = 0.522kg / m3. Performance Table with damper fans refer to the parameter when the damper blade is fully open (0 °) when. Many often occurs excess or shortage flow in use, the reasons for this phenomenon. As large a small event in the course of the phenomenon, mainly due to the resistance of the pipe network in big, sometimes small. As in the course bb24 temperature fan, gradually reduced over a longer period, or a sudden decrease in a short time, mainly due to the fan flow channel or pipe blockage. After installation, excessive or insufficient formal flow phenomenon occurs during operation, the main reasons are the following: the pipe network resistance difference between the actual value and the calculated value is too large by the general pipe network characteristic equation: P = KQ2 w473 hot fan, Where K- K drag coefficient as the actual value is less than the flow rate increases when calculating K, otherwise the flow rate decreases. 2. Select the fan itself is not considered when the full impact of the deviation △ P pressure value, the actual value is positive when the fan is poor, the flow rate increases, a negative difference temperature fan, the flow rate decreases. 3, the fan occur in the course of heavy traffic or too small can be used to regulate the flow damper. When adjusting the doors open, the flow rate is still too small w548 hot fan, the elimination of one of the following methods can be used: ① change the pipe network, reducing the drag coefficient of the tube network. ② increase fan speed, but not greater than the maximum speed of the aircraft performance table number. ③ Select the new high pressure turbine. W4-73 high temperature fans for conveying non-corrosive, not spontaneous combustion, the maximum temperature does not exceed 500 ℃ high-temperature gas, if a large amount of gas dust should be equipped with front air inlet fan collection efficiency of not less than 85% dust removal device, in order to improve fan life. Where the inlet conditions equivalent performance to adapt those can be selected. Impeller material is heat-resistant stainless steel, static and dynamic balance and speed test. Transmission Group is composed of the main shaft, heat sink, cooling the bearing housing, bearings.
