Determining the Equation of the Impact Forces Produced by Water Jets Used in Sewer Cleaning

Since 1950, the use of water jets has grown in the field of cleaning pipes and sewers. The regular cleaning of the materials deposed in sewer networks is realised especially with equipment that uses high pressure water jets. The functioning of this equipment is dependent on certain process parameters that can vary, causing variations of the impact forces. The impact force directly affects the cleaning of sewer systems. This article is a part of research activity what is centered on the study of the cleaning head - sewer system. The purpose of this research is to determine an equation of the impact forces of the water jet that depend on process parameters. The research method used is that of the full factorial plan. For the experimental determination of the impact forces a stand for generating water jets and a device for measuring the forces of impact are used. The equation of the impact forces measured is determined using the software Minitab 17.
