For small-diameter pipeline cleaning, we often use high-pressure cleaner as the main means of clarity, the use of high-pressure cleaner for pipeline cleaning with high cleaning efficiency, a wide range of applications, no pollution, and other advantages. In the cleaning process, due to the specificity of the small diameter pipeline, we will be different for the high-pressure cleaner pressure, flow rate, and other major parameters of the choice, in general, the small diameter pipeline is mainly annular distribution and curvature of the impact of the pipeline, making it and the general plane of the cleaning is very different, and with the reduction in the diameter of the pipeline, the specificity of this is more and more obvious. The following is a detailed introduction to the main factors affecting the high-pressure cleaner used to clean small-diameter pipes.
1. Target distance and striking force
We often use the method of increasing the length of the starting section of the jet to extend the jet cleaning range, which is conducive to improving the cleaning efficiency of the high-pressure cleaner, at the same time, near the front of the high-pressure water encountered the inner wall of the pipeline, as a result of the refraction of the resulting water cushion, a large degree of buffering the cleaning effect of the jet at the back end, so to make the cleaning of the striking force to become larger, you should choose a good cleaning point and the target distance of the jet coincide.
2. Pressure and flow
Generally speaking, the pressure and flow and high-pressure cleaner power are proportional to the relationship, but the two in the cleaning effect on the dirt are very different. When the pressure is unchanged, we can increase the cleaning speed and jet flow to strip the dirt from the substrate.
3. Impact angle and cleaning speed
The impact angle of the water jet refers to the cleaning plane, the axis of the nozzle, and the plane being cleaned between the normal angle. In other conditions are the same, different impact angle of the water jet cleaning effect is different. At the same time, the impact angle of the water jet is also related to the direction of movement of the jet. When the impact angle is biased towards the forward direction of the jet, due to cleaning after the water will carry the dirt has been broken at a certain speed to wash the surface to be cleaned, the water in the pipeline wall rebound will also accelerate the generation and growth of cracks, thus increasing the cleaning effect and improve the cleaning efficiency.
4. Nozzle and nozzle
For small-diameter pipelines, due to workspace restrictions on the external dimensions of the nozzle of the high-pressure cleaner, so generally a two-dimensional self-rotating nozzle. Cleaning, the nozzle and high-pressure hose connected to the nozzle by its rear jet stream generated by the counter-thrust forward, relying on the reverse torque generated by the jet to drive the rotating set of rotation. In this type of nozzle in addition to the necessary rear holes, there will be front or radial injection holes. The rear jet holes are mainly used to generate propulsion and sewage, radial holes are mainly used for cleaning, and the front jet holes of the rotating wheel body are mainly used to clear the blockage.
