Abstract:
According to theory of the high p ressure waterjet for cleaning, combines the special parameters of smalldiamterp ipeline 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 p ressure and flux ofwater, distance and slugging force, the angle of incidence and the velocity of cleaning, and the choosing and matching, between the angle of sp read and the shape of the waterjet aswell as the currentmethod for choosing the related nozzle and sp rayer in small diameter p ipeline cleaning, thereby p roviding the basis for upgrading the efficiency of the high p ressure water for p ipeline cleaning.
Key words:
high p ressure waterjet; cleaning efficiency; p ipeline; small diameter
