Vacuum pump gas delivery pipe plug how to do

In fact, the flow of material in the vacuum pump gas delivery pipe is actually complicated and changeable. The material particles are sometimes separated from the gas flow, or settled in the bottom of the pipe to form agglomerates, or adhered to the pipe wall and gradually thicken . Once accumulated in a local section of the tube to the development of stuffed in the entire pipeline wear direction. And stay still, it will lead to complete stop the delivery process. This phenomenon, which we call "blockage." Vacuum pump gas delivery pipe plugging how to do In the vacuum pump gas delivery process often appear blocked pipe, which gives the dense phase pneumatic conveying has brought a lot of inconvenience, the main reasons are: the impact of system parameters set, the impact of gas source , The impact of the medium being transported, the effects of pipeline leakage, and other influences (such as unreasonable pipeline design). In order to prevent plugging pipe, it is necessary to fully consider the influence of various factors on the conveying performance and ensure the best working parameters of the conveying system; the conveying gas is clean and dry; the conveying devices and pipelines are regularly cleaned; the pipelines are regularly repaired to prevent the occurrence of seepage Leakage. Once found plugging phenomenon can immediately use "anti-pumping" method of blocking. Gas source with oil, with water, the ash particles will be bonded to each other, the flow resistance surge, resulting in blocked tube. So found gas source with oil, with water, should immediately stop the warehouse pump operation, stop the pump operation, open its exhaust valve inspection. If it is found that there is oil or water discharge, it should close its exit door, in accordance with the above reasons, eliminate consumption. That is, quickly open the gas tank drain valve, the use of residual gas in the pipeline to take away the oil or water, and then open the backup air compressor to charge the pipeline, and then repeat the previous process until the pure air is discharged.
