高压射流清洗应用场景：管壳换热器、板式换热器、凝汽器、冷凝器、预热器、空冷器、初冷器、再沸器、蒸发器、管道、反应釜、水冷管等设备应用High pressure jet cleaning application scenarios: shell and tube heat exchangers, plate heat exchangers, condensers, condensers, preheaters, air coolers, primary cooler, reboiler, evaporator, pipeline, reactor, water cooling pipe and other equipment applications.
高压水射流清洗是利用经设备增压系统加压的水由喷头射出形成高速水射流，这种水射流有很高的冲击和剥削能力，可将管壁上的结垢、金属氧化物和其他附着物清除，主要用于换热器，管道，槽罐的清洗。凯利清洗2004年开始应用高压水射流清洗技术，已经在国内完成几百套设备的高压水射流清洗施工。尤其针对堵塞换热，高压水有独特的优势，采用二维旋转喷头，可对12-50直径的管束进行高压射流疏通清洗。凯利公司经过多年研究，运用高压水射流和超声波结合技术应用清洗煤制油精密过滤器的清洗，取得突破性成果。High pressure water jet cleaning is the use of the pressure equipment pressurization system of water formed by the injection nozzle of high speed water jet, the jet of water has very high impact and exploitation ability, can be pipe fouling and metal oxide on the wall and other attachments removed, mainly used for heat exchanger pipe cleaning tank. Kelly began to use high pressure water jet cleaning technology in 2004, and has completed several hundred sets of high pressure water jet cleaning construction in China. Especially for blocking and heat transfer, high pressure water has unique advantages. Using two dimensional rotating nozzle, the 12-50 diameter tube can be cleaned by high pressure jet. After years of research, Kelly has applied high pressure water jet and ultrasonic technology to clean coal and oil filter, and achieved breakthrough results.
高压水清洗的优点Advantages of high pressure water cleaning
（7）在设备维修中，能较好恢复设备性能、延长设备寿命； 与其他物理清洗技术相比，高压水射流清洗也有着独特的优势。Advantages of high pressure water cleaning
(1) when cleaning quality is good, high pressure water jet cleaning pipeline and heat exchanger hole, can remove dirt and blockage in the pipe, and see the metal body. High pressure water jets with huge energy and supersonic movement can completely destroy hard dirt and clogging, but have no damage to the metal.
(2) the cleaning speed is fast. Due to the combined crushing effect of water jet scour, wedge splitting, cutting and grinding, it can quickly destroy the scaling. It is several times faster than traditional chemical method, sand blasting method, simple machine and manual method.
(3) no environmental pollution. Because high pressure water jet cleaning is based on clear water as medium, water as medium, water jet, odorless, tasteless, non-toxic, and jet atomization after ejection, it can also reduce the concentration of air dust in the operation area, so it will not cause any pollution.
(4) for a wide range of high pressure water jet cleaning can shape and structure of complex parts, can be cleaned in the narrow space and complex operating environment under the condition of poor, has no special requirements for equipment, material properties, shape and scale types, only requires the ability to direct, therefore its application is very extensive.
(5) it is easy to mechanization and automation.
(6) energy saving, water saving, cleaning cost low pressure water jet used medium is tap water, it is easy to source, common.
(7) in equipment maintenance, it can better restore equipment performance and extend equipment life. Compared with other physical cleaning technologies, high pressure water jet cleaning has unique advantages.
This “water jet” is generally more than doubling the Maher number, with a huge strike energy and can accomplish different kinds of tasks. The technology of using this highly concentrated water jet to complete various cleaning operations is called the “high pressure water jet cleaning technology”.
The high pressure water jet is used for cleaning, which has the advantages of high efficiency, low cost, no damage to the workpiece, no pollution to the environment, easy operation and safety. Germany, the United States, Japan and other developed countries after 1980, high pressure water technology has been widely applied. As an environmental protection technology, instead of polluting the environment, chemical cleaning is popular in power generation, petroleum, chemical industry, foundry, nuclear power plants, airports, cement and other industries.
