Yantai Durable Railway Insulator Water Flushing Equipment High Voltage Cleaning Machine

For the cleaning of small-diameter pipelines, we often use high-pressure cleaning machines as the main cleaning method. Using a high-pressure cleaning machine to clean pipelines has high cleaning efficiency and a wide range of applications. Will the following editor provide a detailed introduction to the main factors that affect the use of high-pressure cleaning machines to clean small diameter pipelines?

1. Target distance and influence: we often use the method of increasing the initial length of spraying to expand the range of spray cleaning, which is conducive to improving the cleaning efficiency of high-pressure cleaning machines. At the same time, high-pressure water near the front end collides with the inner wall of the pipeline and creates a water cushion due to refraction. It greatly reduces the cleaning effect of the rear spray. Therefore, in order to increase the impact during cleaning, the cleaning point should be selected and the target distance of spray should coincide.

2. Pressure and flow rate: Typically, pressure and flow rate are directly proportional to the power of a high-pressure cleaning machine, but they differ in terms of cleaning dirt. When the pressure is constant, we can remove scale on the substrate by increasing the cleaning speed and spraying speed.

3. Impact angle and cleaning speed: The impact angle of the water jet is the angle between the nozzle axis and the normal of the plane to be cleaned in the cleaning plane. When other conditions are the same, different impact angles will result in different water jet cleaning effects. Meanwhile, the impact angle of the water jet is also related to the direction of its motion. When the impact angle is biased towards the forward direction of the injector, the water flow will accelerate the generation and growth of cracks after rebound, as the cleaned water will carry broken dirt at a certain speed to clean the surface to be cleaned. The pipe wall has increased the cleaning effect. Improve cleaning efficiency.

4. Nozzle: For small diameter pipes, due to the limited workspace, the size of the high-pressure cleaning machine nozzle is usually a two-dimensional rotating nozzle. During the cleaning process, the nozzle is connected to the high-pressure hose, and the nozzle moves forward through the reverse thrust generated by the rear spray of the nozzle. The rotating torque is driven by the reverse torque generated by the spray. In addition to the necessary rear spray holes, this type of nozzle also has front or radial spray holes. The rear nozzle holes are mainly used to generate thrust and sewage, the radial holes are mainly used for cleaning, and the nozzle holes in front of the wheel body are mainly used for cleaning.
