Main factors affecting the use of ultra high pressure cleaning machine to clean small diameter pipes

For small diameter pipe cleaning, we often use Ultra high pressure cleaning machine As the main cleaning method. High pressure cleaning machine is used to clean the pipeline, which has high cleaning efficiency and wide application range. In the cleaning process, due to the particularity of small diameter pipe, we have different choice of main parameters, such as the pressure and flow rate of ultra-high pressure cleaning machine. Generally, the small diameter pipe mainly has annular distribution and curvature effect, which makes it very different from the conventional plane cleaning. With the decrease of pipe diameter, this characteristic becomes more and more obvious. The following details the main factors that affect the use of ultra-high pressure cleaning machine to clean small-diameter pipes?
 
1. Target distance and influence
 
We often use the method of increasing the start length of spray to expand the cleaning range of spray, which is conducive to improve the cleaning efficiency of high-pressure cleaning machine. At the same time, the high-pressure water near the front end impinges on the inner wall of the pipe and generates water cushion due to refraction. It greatly cushions the cleaning effect of the rear spray. Therefore, in order to maximize the impact in the cleaning process, the cleaning points should be selected and the spraying target distance should be consistent.
2. Pressure and flow
 
Generally, the pressure and flow rate are directly proportional to the power of the ultra-high pressure cleaning machine, but they are completely different in cleaning dirt. When the pressure is constant, we can remove the scale on the substrate by increasing the cleaning speed and spraying speed.
 
3. Impact angle and cleaning speed
 
The impact angle of water jet is the angle between the nozzle axis and the normal of the cleaned plane. Under the same other conditions, different impact angle will make the effect of water spray cleaning different. At the same time, the impact angle of water jet is also related to the movement direction of water jet. When the impact angle deviates from the forward direction of the jet, the washed water will carry broken dirt to clean the surface to be cleaned, so the water flow will accelerate the generation and growth of cracks after rebound. Tube wall, thus improving the cleaning effect. Improve cleaning efficiency.
 
4. Nozzle
 
For small diameter pipes, the size of the nozzle of the ultra-high pressure cleaning machine is limited by the working space, so it is usually a two-dimensional rotating nozzle. In the cleaning process, the nozzle is connected to the high-pressure hose, and the nozzle moves forward through the reverse thrust generated by the spray nozzle, and the rotation torque is driven by the reverse torque generated by the spray. In addition to the necessary back jet holes, this type of nozzle also has a front jet hole or a radial jet hole. The rear nozzle hole is mainly used to generate propulsion and sewage, the radial hole is mainly used for cleaning, and the nozzle hole at the front of the wheel is mainly used for cleaning.
