| Abstract: | According to theory of the high pressure water-jet for cleaning,combines the special parameters of small-diamter pipeline cleaning,chooses the key parameters that influence the effect of cleaning and rationally categorizes the parameters that influence each other.It also makes a detailed analysis of the pressure and flux of water,distance and slugging force,the angle of incidence and the velocity of cleaning,and the choosing and matching,between the angle of spread and the shape of the water-jet as well as the current method for choosing the related nozzle and sprayer in small diameter pipeline cleaning,thereby providing the basis for upgrading the efficiency of the high pressure water for pipeline cleaning. |
