When, pipe resistance and pressure-drop in pipeline are exactly to have to emphasis to consider the problems of, such as design unreasonable, it will bring a large amount of power-equipments
Power attenuation, greatly waste of energy and equipment investment.
When coalmine ventilation pipeline is built, very more main pipes can be run into, branch pipe intersects the situation of connection, this mode of communicating
General right angle welding is docked or connected using right-angle tee, as shown in Figure 1.
This right angle connection mode belongs to the rapidly avried flow form that fluid flows in pipeline, in this manner, in pipeline
The inertia force that can not ignore can be formed, and the frictional force in pipeline also can be important on the section perpendicular to streamline, and meeting exists
Extremely complex resistance is partially formed, for example complicated turbulent gas can be formed at fluid junction, into the resistance in pipeline
Increase.
Current ground coal mine gas drainage pumping plant and wind turbine use at equipment ventilation in parallel or main pipe branch pipe docking
Be also all right angle connection, for large-scale vacuum pump or fan, since ventilation quantity is very big, inner air tube flow velocity is very high, resistance
Power problem can increase the meaningless power consumption of vacuum pump or wind turbine, simultaneously because pipeline junction is because the gas that resistance is formed
The increase for resonance noise when reasons bring pipeline work that turbulent flow is formed brings the working environment of worker very big noise dirty
Dye.
