This session will inform sewer cleaning operators how the length of their high-pressure hose affects the overall performance of the sewer cleaning nozzle and its ability to remove debris, grease, and roots from sewer lines. The following factors will be discussed: 1. Pump configurations regarding GPM, pressure ratings and pressure regulators. 2. How the size and length of the sewer hose affects the flow and pressure of high-pressure water as it exits the sewer hose. 3. Pressure losses based upon various hose use situations. Performance of the rotation nozzle will also be discussed. We will examine how to achieve maximum nozzle performance, such as rotation speed of the nozzle, determining correct orifice size, and travel speed of the nozzle. This information will be presented through charts, graphs and video-based media and pictures. Testing of the physics presented in this presentation will be demonstrated through video captured during live field demonstrations.
After this session, attendees will be able to:
1. Discuss proper use and maintenance of rotation nozzles.
2. Apply the information to determine if your rotation nozzle is working properly.
3. Determine the proper orifice to use in a rotation nozzle for maximum performance.
4. Apply the information to determine approximate pressure loss due to the length of sewer hose in use during the cleaning process.
Ideal Audience: Maintenance workers and sewer cleaning operators who use rotation nozzles for cleaning pipelines.
