High-pressure cleaning Introduction to high-pressure water jet cleaning technology
High-pressure water jet cleaning is a high-tech cleaning technology that has emerged internationally in recent years. The so-called high-pressure water jet is to pressurize ordinary tap water to hundreds or even thousands of atmospheres through a high-pressure pump and then spray it through a special nozzle (the hole diameter is only millimeters) at an extremely high speed (m/s) to eject a stream of water with highly concentrated energy. . This small stream of water has huge impact energy like a small bullet. It can cut steel plates, cast sand, clean metal, and remove rust. It can also remove salt-alkali scale and various blockages on the inner wall of the pipe. Utilize this huge energy. The water flow for cleaning is high-pressure water jet cleaning.
The main advantages of high-pressure water jet cleaning
Low cleaning cost. First of all, the medium used by high-pressure water jet is tap water, and its source is easily ubiquitous. During the cleaning process, due to energy It is powerful and can be cleaned without adding any fillers and detergents, so the cost is very low. Secondly, it saves water and energy. This cleaning method is different from fire water. It is a fine jet spray. The diameter of the nozzle is only millimeters, so the water consumption is only cubic meters/hour. The power of the power is kilowatts, so it is a water-saving and energy-saving equipment.
The cleaning quality is good. When cleaning the pipes and the inner holes of the heat exchanger, all scales and blockages in the pipes can be removed, and the metal body can be seen. It has huge energy. And the high-pressure water jet moving at supersonic speed can completely destroy hard scales and blockages but has no destructive effect on metal. At the same time, because the pressure of high-pressure water is less than the compressive strength of metal or reinforced concrete, it has no effect on pipelines. Destructive effect. Achieve high-quality cleaning.
Fast cleaning speed. Due to the composite crushing effects of water jets (called water bombs abroad) such as scouring, chopping, shearing and grinding, the scale can be immediately broken and fallen off. It is faster than traditional The cleaning speed of chemical sandblasting and shot blasting methods is several to dozens of times faster with simple mechanical and manual methods.
Environmental pollution-free water jet cleaning does not produce a large amount of dust that pollutes the atmosphere and damages the atmosphere like sand blasting and shot blasting and simple mechanical cleaning. Human health. Unlike chemical cleaning, which produces a large amount of acid-base waste liquid that pollutes the soil and water quality. Water jet uses tap water as the medium, is odorless, tasteless and non-toxic. After atomization, the water jet can reduce the air dust concentration in the working area. It is an important measure for my country's environmental protection cause to reduce atmospheric dust from mg/cubic meter by other methods to mg/cubic meter below the national safety standard, eradicate the source of silicosis and eliminate the poisonous acid-base waste liquid.
It is a purely physical method, so it has no corrosive effect on metal.
Wide range of applications: Any part that the water jet can directly hit, whether it is the inner cavity of pipes and containers or the surface of equipment, whether it is hard scale or solid blockage It is quickly separated from the mother body and cleaned thoroughly. This cleaning method has no special requirements on the material properties, shape and scale type of the equipment. It only requires direct irradiation, so it is widely used.
The main object of high-pressure water jet cleaning
Various specifications of water pipes, industrial water pipes, industrial and mining enterprises and residential areas, sewage pipes, slag pipes, rain pipes, gas pipes, flue pipes, oil pipes and blockages in two-phase flow pipes
Various heat exchangers, condensers, air preheating Scales in refrigerators, rehydrators, dust collectors, evaporation tanks, reaction kettles, heating devices, etc.
Scale, salt scale, alkali scale and materials in various boiler tanks and containers
Scale in heating systems and air-conditioning equipment (special treatment is required) )
Attachments on the internal and external surfaces of various large buildings and equipment.
The application conditions and scope of high-pressure water jet
The diameters of various types of pipes, generally upper and lower pipes and industrial water pipes, are mostly in millimeters. Our equipment can treat any scale in any length of millimeters (the length can be pushed in meters at a time). Efficient cleaning of pipes and clogged pipes. Application conditions: The pipe hole is blocked or semi-blocked and the surrounding or bottom structure of the pipe hole is cleaned. The high-pressure hose with a nozzle is sprayed to the surrounding scale to automatically advance through the spray reaction force for cleaning and descaling.
The inner diameter of various types of tube heat exchangers is generally about millimeters and meters. We use steel spray guns of corresponding lengths and various types of nozzles to attack and crush the scale in the tubes and then discharge them out of the tubes.
Cleaning of boilers, heaters, large containers and other equipment mainly relies on high-pressure water jets and corresponding spray guns and nozzles. When high-pressure water jets cannot be directed, chemical methods are supplemented.
