For the cleaning of small-diameter pipes, we often use high-pressure cleaners as the main means of clarity. Using high-pressure cleaners to clean pipes has the advantages of high cleaning efficiency, wide application range, and no pollution. In the cleaning process, due to the particularity of small-diameter pipes, the selection of main parameters such as pressure and flow rate of high-pressure cleaners will also be different. Generally speaking, small-diameter pipes are mainly affected by annular distribution and curvature, making their It is very different from general plane cleaning, and as the diameter of the pipe decreases, this particularity becomes more and more obvious. The following editor will introduce to you in detail what are the main factors that affect the use of high-pressure cleaners for cleaning small diameter pipes?

1. Target distance and striking power

We often use the method of increasing the length of the jet starting section to extend the jet cleaning range, which is beneficial to improve the cleaning efficiency of the high-pressure cleaner. , which greatly buffers the cleaning effect of the rear jet. Therefore, in order to increase the impact force during cleaning, a good cleaning point should be selected and the target distance of the jet coincides.

2. Pressure and flow

Generally speaking, the pressure and flow are proportional to the power of the high-pressure cleaner, but there is a big difference between the two in the cleaning effect of dirt. When the pressure is constant, we can lift the scale from the substrate by increasing the cleaning speed and jet flow.

3. Impact angle and cleaning speed

The impact angle of the water jet refers to the angle between the axis of the nozzle and the normal to the plane being cleaned in the cleaning plane. When other conditions are the same, different impact angles make the cleaning effect of water jets different. At the same time, the impact angle of the water jet is also related to the moving direction of the jet. When the impact angle is deviated to the forward direction of the jet, since the water flow after cleaning will carry the broken dirt and wash the surface to be cleaned at a certain speed, the water flow will also accelerate the formation and growth of cracks after rebounding on the pipe wall, thereby increasing the cleaning effect. Improve cleaning efficiency.

4. Nozzle and Nozzle

For small-diameter pipes, since the working space limits the overall size of the nozzle of the high-pressure cleaner, it is generally a two-dimensional self-rotating nozzle. When cleaning, the nozzle is connected with the high-pressure hose, the nozzle moves forward by the reverse thrust generated by its own rear jet, and the rotating sleeve is driven to rotate by the reverse torque generated by the jet. In addition to the necessary rear nozzles, such nozzles also have front nozzles or radial nozzles. The rear nozzle holes are mainly used to generate propulsion and sewage, the radial holes are mainly used for cleaning, and the front nozzle holes of the rotary wheel are mainly used to clear blockages.
