Since the water temperature in the water tank of the sprinkler is kept at a high temperature, the hydrocarbons in the water will be combined with calcium and magnesium ions to form water-insoluble calcium carbonate and magnesium carbonate, commonly known as water alkali. Then, as the water evaporates and concentrates, the water alkali content increases and reaches saturation, forming scale. Therefore, adding pure water containing higher concentrations of calcium and magnesium ions will result in the formation of scale more easily than the addition of ordinary tap water. Therefore, adding this pure water to the sprinkler tank has no effect on suppressing the scale formation of the tank.
The hazard of scale in the circulating waterway of sprinkler
As we all know, sprinkler tanks function as heat sinks under normal operating conditions, but once scales form around the tanks of the sprinklers, they greatly affect the cooling effect of the tank. Because the thermal conductivity of scale is very low, it is only 1/25 of that of cast iron and 1/50 of that of brass. It forms scales in the cylinder lining and the water channel of the cylinder head, which causes the local area to rise due to poor heat dissipation, which can cause the engine to rise. Cracks and cylinder head deformations occur in weak parts. It also not only deteriorates the cooling performance of the cooling system, but also causes local high temperature areas, deteriorates the lubrication conditions, increases the engine temperature, and accelerates the wear of the sprinkler engine system; it also blocks the heat pipe or cooling system piping, greatly reducing heat transfer. The efficiency of overheating the sprinkler engine directly jeopardizes the safety of the driver.
Scale cleaning method
1, manual cleaning method: the sprinkler tank needs to be removed, with an artificial hammer, scraping, shovel, etc. to remove scale; descaling, low efficiency, labor intensity, not easy to clean, easy to cause secondary damage to the tank.
2. Ordinary scale cleaning agent: The tank needs to be dismantled. The cleaning is not complete, the odor is large, and the corrosion is strong. It can easily cause aging of the tank and shorten its service life.
3, professional sprinkler tank descaler: no need to disassemble can be cleaned, but also without stopping the cleaning conditions. The dedicated scale cleaning agent can be directly poured into the sprinkler water circulation system, allowing it to be soaked, idling cycled or after 20-30 minutes of travel, the sprinkler tank and the system's internal scale remover will be discharged, and the water can be washed repeatedly. Effectively remove scale, rust, mud and various harmful substances in the engine water circulation system.
Aircraft Engines Honeycomb Seals
Honeycomb sealing can produce good sealing effect, reduce airflow loss, and improve aerodynamic efficiency. The Honeycomb Seal at the top of the blade also has a good dehumidification effect, which can effectively protect the blades from erosion by water vapor.
