Nowadays, the construction pace of modern cities is getting faster and faster, and the scale of cities is constantly expanding. The scale of infrastructure that is suitable for them has also been continuously expanded. The amount of water used in cities is increasing, the displacement is also getting larger, and the management of sewage pipelines is increasing. There are more and more jobs for maintenance, maintenance, and dredging. Due to the frequent inhabitants of dumping sewage and other sundries as well as the cement mortar on the construction site in the sewers, these debris are precipitated and deposited. Excessive siltation can cause blockage of the pipeline. If it cannot be cleared and dredged in time, it will cause overflow of sewage, pollute the environment, and cause economic losses. It is impossible to clean these fouls by traditional methods, so it must be washed with high-pressure water jets here. Pipeline , specifically with high-pressure water jet cleaning pipe can be cleaned? Let's take a look.
High-pressure water jet cleaning is a high-tech cleaning technology that has risen internationally in recent years. The so-called high-pressure water jet is the use of high-pressure pipe dredge vehicles to press common tap water through high-pressure pumps to several hundred to thousands of atmospheric pressure, and then through a special nozzle (only 1-2 mm in diameter), at an extremely high speed (200- 500 meters/second) A highly concentrated stream of energy that is ejected.
Because of the high pressure, this continuous stream of small water can be as powerful as a small bullet. It can cut steel plates, remove sand from castings, remove metal from rust, and effectively remove various blockages such as salt, alkali, and scale on the inner wall of pipes. The use of this highly energy-rich water stream for cleaning is a high-pressure water jet cleaning.
High-pressure water jet cleaning mainly has the following advantages
1, metal corrosion: As a result of pure physical methods, it does not have any corrosive effect on the metal.
2. Low cleaning cost: First, the medium used for high-pressure water jets is tap water, and its source is easy and ubiquitous. In the cleaning process, because of its powerful energy, it can be cleaned without adding any fillers and detergents, so the cost is very low. Secondly, saving water and energy. This kind of cleaning method is different from firefighting water and is a fine jet injection. The diameter of the nozzle used is only 0.5-2.5mm, so the water consumption is only 3-5 cubic meters per hour, and the power used is 37-90. Kilowatts, it is a water-saving energy-saving equipment.
3, cleaning speed: due to the water jet (above, called water bombs) of the scouring, deterrence, shear, grinding and other composite crushing effect, the debris can be immediately broken off. It is several times to dozens of times faster than conventional chemical methods, sand blasting methods, simple mechanical and manual methods.
4. Good cleaning quality: When cleaning the inner hole of the pipeline and the heat exchanger, all the foulants and plugs in the pipe can be removed and cleaned, and the metal body can be seen. High-pressure water jets with huge energy and moving at supersonic speeds can completely destroy hard foulants and plugs, but have no destructive effect on metals. At the same time, since the pressure of high-pressure water is less than the compressive strength of metal or reinforced concrete, there is no destructive effect on the pipeline. Achieve high quality cleaning.
5. No environmental pollution: Water jet cleaning does not produce as much dust as sand blasting and simple mechanical cleaning, polluting the atmosphere and damaging human health. Also, unlike chemical cleaning, there are a lot of acid and alkali wastes that pollute roads, soil and water quality. The water jet is based on tap water as the medium, odorless, odorless, and non-toxic. After the atomized jet is atomized, the concentration of air dust in the working area can be reduced, and the atmospheric dust can be reduced to 80 mg/cubic meter from other methods to the national regulations. The safety standard below 2 mg/m3, eradicating the source of silicosis, eliminating the flow of poisonous acid and alkali waste, is an important measure for China's environmental protection cause.
6. Wide range of applications: Wherever the water jet can directly reach, whether it is the pipeline and the container cavity, or the equipment surface, whether it is a hard fouling material or a solid plug, it can be quickly removed from the mother, completely It is clean and clean. This kind of cleaning method has no special requirements on the material, characteristics, shape and scale of the equipment. It only requires direct lighting, so its application is very extensive.
The principle of high pressure water jet cleaning
It uses high-pressure pump to pump out high-pressure water, and it reaches a nozzle through a certain pipeline, and then converts high-pressure and low-flow water into high-pressure and high-velocity jets. The jet then uses its high-impact kinetic energy to continuously clean the jets. The surface, so that the scale off, and ultimately achieve the purpose of cleaning.
High pressure water jet cleaning features
(1) Select the appropriate pressure level, high-pressure water jet cleaning will not damage the substrate of the equipment being cleaned.
(2) It is flushed with ordinary tap water at high speed, so it does not pollute the environment, does not corrode equipment, does not cause any mechanical damage, and removes special scale that is insoluble or insoluble with chemical cleaning.
(3) The cleaned equipment and parts do not need to be cleaned.
(4) It can clean components with complex shapes and structures, and can be cleaned in places with narrow space, complex environments, harsh and harmful environments.
(5) It is easy to realize mechanization, automation and digital control.
(6) Energy conservation, high cleaning efficiency, and low cost.
Why use high-pressure water jets to clean the pipeline
1. The traditional way to solve the blockage problem is to clear the bamboo slips and dredge machines, and these methods can only solve the temporary circulation of the sewage, but cannot fundamentally solve the problem.
2. Analysis of the causes of pipeline plugging: Vegetable oils, animal fats, feces and other viscous materials flow into the pipeline, stick to the wall of the pipeline, form a body of scale, hair, rags, decoration debris, microbial reproduction will be formed in the inner wall of the pipeline The body of scale accumulates over time, causing poor circulation or blocking of pipes.
3. High-pressure water jet cleaning Using water as the medium, the special equipment system enables water to produce ultra-high pressure water streams with multiple beams and multi-angles to clean and clear the dirt and debris in the pipeline. The high-pressure water jet cleaning application has a wide range of applications, high efficiency, cost savings, short construction period, no chemical reaction, no environmental damage, no unnecessary troubles to customers, and is the first choice for difficult problems.
Summary: The relevant information on the use of high-pressure water jets to clean the pipeline is introduced for everyone. I hope this article will be helpful to everyone.
