In the cold winter, you are afraid that you will be greeted by a windscreen frost in the morning when you are rushing to start a sewage suction truck or a suction truck. When you use a wiper to toss it for a long time, it is not clean. No way, because of the cool days of winter, the temperature difference between the inside and outside of the car is large, the water vapor condenses on the windshield, and it is normal to add some frost to you after the snow. To deal with this thing, it is difficult to work with a wiper, and it is very easy to damage the wiper strip, so you have to use a little clever trick. You will have to prepare some methods soon after entering the winter season: Prevention of icing on the windshield of suction-cleaning vehicles and suction trucks: The icing on the windshield glass is caused by the temperature difference between the inside and outside of the car. When the temperature inside the vehicle is high, the frost (snow) on the windshield melts. After the temperature is lowered, the temperature is reduced. It will form ice. Therefore, when you stop the big nose suction truck and suction truck, first open the door ventilation, so that the temperature inside the suction truck and suction truck is reduced to the outside temperature, which can greatly reduce the degree of ice on the windshield, even Do not freeze. Physical de-icing method: Prepare a rigid plastic blade, such as hand-side can not use ID card or co-driver's license instead. When there is snow and ice on the suction truck and suction truck glass, use a plastic scraper to gently scrape in the same direction, but remember not to scrape back and forth to prevent scratching the glass. Of course, if there is a dedicated glass frost shovel is more convenient and faster. The snow on the suction truck, suction truck, and body can be removed with a soft, small broom. For example, a home sweeping broom, preferably a soft plastic brush, does not damage the paint or dampness. Chemical deicing methods: Normal antifreeze glass water - Glass water with antifreeze added. Spray the frost-proof glass water on the glass on the suction truck and suction truck, and wait for a while to remove the basically melted ice with a plastic scraper. Windshield Concentration Deicing Additive, a powerful de-icing agent, is added directly to common cleaning fluids to make it an effective de-icing fluid to melt thin ice and frost, reducing the risk of re-freezing. Spray Deicing Agent - A high-speed anti-icing spray concentrate for icing windows and wipers that freezes without damaging the car's surface, preventing it from freezing and contaminating again. Windshield glass removes ice and snow - it can remove ice and snow at a low temperature below 30°C. At the same time, it can prevent the icing truck, suction truck windshield and water accumulation from freezing, and does not damage the surface of the vehicle. After cleaning, the glass is clean and smooth. Leave traces.
The finned tube is to improve the heat exchange efficiency. By adding fins on the surface of the heat exchange tube, the outer surface area (or inner surface area) of the heat exchange tube is increased, so as to achieve the purpose of improving the heat exchange efficiency. Such a heat exchange tube . Usually used for heat exchange between liquid and gas.
Finned tube is a heat exchange element. As a heat exchange element, finned tubes usually work under high-temperature flue gas conditions for a long time. For example, the finned tubes usually used in boiler or harsh environments, high temperature and high pressure, and in a corrosive atmosphere. This requires that the finned tubes should have high anti-corrosion properties, Anti-wear properties, lower contact resistance, higher Stability and anti-dusting ability.
There are many types of finned tubes, and new varieties are constantly emerging. According to the classification of processing technology, there are extruded fin tube; high frequency welded finned tubes; rolled formed finned tubes; suit formed finned tubes ; cast finned tubes; tension wound finned tubes; Inserted tubes.
According to the shape of the fins, there are square finned tubes; circular finned tubes; spiral finned tubes; longitudinal finned tubes; corrugated finned tubes; spiral serrated fins Helical Serrated Finned Tubes; pin-shaped finned tubes; integral plate-shaped finned tubes; inner finned tubes.
According to whether the fin material of the finned tube is the same as that of the base tube, it can be divided into: single metal finned tube, bimetallic composite finned tube.
Single metal finned tubes are classified by material into copper finned tubes; aluminum finned tubes; carbon steel finned tubes; stainless steel finned tubes; cast steel finned tubes.
