| The main application and functional manifestation of high-pressure cleaners in urban development are reflected in the cleaning of pipelines, cleaning of heat exchangers, cleaning of heat exchangers, cleaning of boiler pipes, and so on. The most used in these projects is the high-pressure cleaner. Next, I will briefly introduce the application of high-pressure cleaners: 1. For general water supply and drainage pipes with a diameter of 150~500mm, timely cleaning of the pipes can alleviate the blockage and corrosion of the pipes caused by the accumulation of urban garbage at any time, and can make the pipes truly reflect their value. 2. Heat exchanger cleaning machine Heat exchanger is a device for heat energy conversion and waste heat utilization, which is widely used in chemical plants, power plants and petrochemical enterprises. Some large enterprises have dozens or even hundreds of heat exchangers in a production base. In the heat exchange process of the cooling water, the chilled water absorbs the heat of the cooling water and raises its temperature. At this time, the Ca(HCO3)2 and Mg(HCO3)2 originally soluble in water will precipitate CO2 under the action of temperature, forming CaCO3 and MgCO3 which are slightly soluble in water. Since the solubility of calcium carbonate and magnesium carbonate decreases with increasing temperature and crystallizes out of water, when these crystallites are continuously deposited on the surface of the heat exchanger, very hard scale will be formed, which not only affects the heat exchange efficiency, but also Will increase energy consumption. In severe cases, it will shut down due to insufficient cooling water flow and reduced pressure, so the heat exchanger must be cleaned after a period of use. 3. Boiler pipes and large water tanks and kettle cleaning machines After boilers, heating pipes, large tanks, and large containers run for a period of time, scaling will inevitably occur. The high-pressure water jet has a composite crushing effect of scouring, wedge splitting, shearing, and grinding, which can immediately break off and wash away the scale, thereby Realize the separation of scale layer and pipe wall. Therefore, high-pressure cleaners are ideal cleaning equipment. When the high-pressure water jet cannot be directed directly, it is supplemented by chemical methods, and its economic benefit is roughly equal to the above. |
