Exploration Of The Main Use Of High-pressure Cleaners in Cleaning Diameter Pipes
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 the 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, our choice of main parameters such as pressure and flow rate of the high-pressure cleaner will also be different. Generally speaking, small diameter pipes are mainly distributed in a ring shape and are affected by curvature. It is very different from general plane cleaning, and as the diameter of the pipe decreases, this particularity becomes more and more obvious.
1. Target range and striking power
We often use the method of increasing the length of the initial section of the jet to extend the cleaning range of the jet, which is beneficial to improve the cleaning efficiency of the high-pressure cleaner. At the same time, when the high-pressure water near the front end hits the inner wall of the pipe, a water cushion is generated due to refraction. , The cleaning effect of the back-end jet is greatly buffered. Therefore, in order to maximize the impact force during cleaning, an optimal cleaning point should be selected and the optimal target distance of the jet should overlap.
2. Pressure and flow
Generally speaking, 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 peel off the dirt from the substrate by increasing the cleaning speed and jet flow rate.
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 of the plane to be cleaned in the cleaning plane. When other conditions are the same, different impact angles make the cleaning effect of the water jet different. At the same time, the impact angle of the water jet is also related to the movement direction of the jet. When the impact angle deviates to the forward direction of the jet, since the cleaned water flow 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, because the working space limits the 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 advances by the reverse thrust generated by the back jet, and the rotating sleeve is driven to rotate by the reverse torque generated by the jet. In addition to the necessary rear nozzles, this type of nozzle will also have front nozzles or radial nozzles. The rear nozzle hole is mainly used to generate propulsion and sewage, the radial hole is mainly used for cleaning, and the front nozzle hole of the rotary wheel body is mainly used for clearing blockage.
