turbo blower operation process will also be subject to resistance from different aspects, which is the main source of energy consumption of equipment, but also the key to affect the operation effect of equipment. In fact, the gas in the pipeline of turbo blower will be driven and resisted at the same time, so that different flow velocities can be obtained.
The resistance of gas flow should be considered in two aspects, one is friction resistance, the other is local resistance. In order to make better use of high-pressure fan, it is necessary to master the control mode of local resistance in high-pressure fan pipeline.
In terms of local resistance, it is the energy loss caused by the change of velocity and direction and eddy current when air flows through the pipeline. That is to say, local resistance will occur when various variable diameter pipes, duct inlet and outlet, valve, elbow tee, four-way, exhaust outlet and so on change.
Therefore, the proportion of local resistance in turbo blower system is relatively large. In order not to affect its normal operation, it is necessary to remember and pay attention to the design, and minimize the local resistance. The usual way is to arrange the pipe as straight as possible and reduce the elbow.
If a round elbow is used, its curvature radius is larger than the diameter of the pipe; the longer the aspect ratio of the rectangular elbow section is, the better; the rectangular right elbow is best equipped with a guide vane. In order to reduce the local resistance of the tee, it is very helpful to pay attention to the connection of branch pipe and trunk pipe, to reduce the angle between branch pipe and trunk pipe, and to keep the velocity of branch pipe and trunk pipe equal.
