Gas distribution in compressed air pipeline
The pressure drop of gas transmission pipeline consists of background pressure and pipeline pressure drop, and the pressure difference at each point is mainly caused by the pressure drop difference, which is affected by the density, viscosity, speed and size of the pipeline. In fluid mechanics, the corresponding pressure drop calculation formula is given. For a gas source, the gas consumption at multiple points is fixed and continuous. No matter how you install the pipeline, it is easy to calculate, but the calculation is quite complicated because there is intermittent gas consumption or large or small gas consumption in the system. That's a calculation test project, and I can't ask it here.
In practical application, according to personal experience, it is suggested to adopt the following methods: ensure that the gas source has enough gas, have a surge tank with appropriate volume, determine the maximum gas consumption of each gas consumption point, select the pipe diameter according to the maximum gas consumption value, and then enlarge it by 2 or 3 levels. All pipes are of the same caliber, and each gas point is equipped with a valve to adjust the air volume. Advantages are less specifications, low installation cost, low pressure loss and low power consumption.
