The influence of the pneumatic conveying system of pipeline leakage
The ash conveying pipe of the positive-pressure dense phase of the pneumatic conveying system is of seamless steel tube except the elbow. Because the ash flow velocity of the ash conveying pipe averages at 8 ~ 12 m/s. After running for a long time, it can make the pneumatic conveying system pipe wear and leak, causing stuck at the back of the tube due to the lower pressure head at the back leakage .It mainly manifests in the following aspects:
(1) The discharging door closed but not well0sealed,causing the short circuit.
(2) The straight pipe joint. In order to compensate for the pipe's heat bilges cold shrink, generally the straight pipe connection using gasket and snap ring. In the installation process, the seal dislocation, card ring by the vibration of the pipeline ash loose and causing leakage; If two straight pipe are of butt joint dislocation at the same time,it can cause the back pipes serious wear and tear and fuel leakage.
(3) the elbow part in the running process will gradually be worn and causes leakage.
Due to the leakage of pipeline and discharging door, it all can reduce the pipeline leakage points of pressure head, causing the thrust not strong enough at the back of the leakage point and block the pipe. If leakage is large, the reaction from the meter cannot be shown, so you should pay special attention to it.
The above is the impact of pipeline leakage of pneumatic conveying system. If you want more knowledge about the pneumatic conveying system, please pay attention to the website updates.
