How to clean solar vacuum tubes
After using solar energy for a long time, a lot of scale will accumulate inside the vacuum tube, reducing water temperature and water flow. How to clean the solar vacuum tube? Let's learn together below.
1. How to clean solar vacuum tubes
1 Use a cloth to clean the dust and dirt on the surface of the vacuum tube to prevent slipping. when disassembling the vacuum tube.
2. Use a screwdriver to pry up the dust ring on the upper end of the vacuum tube and slide it down about a foot.
3. Wearing non-slip, heat-resistant gloves, grasp the outermost vacuum tube firmly and slowly rotate it upwards. During rotation, the vacuum tube will enter the water tank about ten centimeters.
4. Onces the vacuum tube has penetrated about ten centimeters, you can see that the bottom of the vacuum tube has come out of the rear bracket. At this time, you should grasp the vacuum tube with both hands and. remove it slowly. Follow the same steps to remove the other vacuum tubes.
5. After the vacuum tube is disassembled, all the water inside the vacuum tube must be drained. If there is a lot of scale inside, you can inject an appropriate amount of clean water and shake the vacuum cleaner. tube continuously, then pour the waste water again. After the poured water becomes clear and there is no more scale in the vacuum tube, you can stop rinsing and pour water.
6. Reinstall the vacuum tube in the reverse order of previous disassembly and install the dust ring in its original position. Once the installation is completed, you can use solar energy normally.
2. What should you pay attention to whensolar vacuum tube cleaning
1 To improve the effect of solar vacuum tube cleaning, you can pour a. appropriate amount of acid into the vacuum tube Descaler, wait about ten minutes, then insert the brush deep into the pipe and pull it back and forth continuously to clean the scale inside, and finally rinse the pipe to clean water.
2. If you want to clean the vacuum tube, you must wait until the solar water temperature drops before starting, and you must wear gloves for cleaning to prevent your hands from being burned by the temperature of the vacuum tube. water. To ensure the efficiency of solar hot water supply, it is recommended to clean the vacuum tubes every two years.
How to clean the solar vacuum tube? What are the cleaning steps
1. Remove the solar vacuum tube, pour in the appropriate amount of white vinegar and let-soak it for 10 minutes, then use a brush to pull it back and forth to remove it. To remove remaining tartar, rinse twice with clean water. But be sure to handle it with care, as vacuum tubes are very fragile.
2. If it is inconvenient to remove the vacuum tube, you can open the water inlet of the solar water heater and pour white vinegar into the water storage tank. Allow the water heater to circulate automatically for 20 to 30 minutes to allow the white vinegar to fully contact all parts, then open the drain and drain the white vinegar that cleaned the scale. Finally, fill the tank with water, circulate it again for two minutes, then drain the circulating water.
Solar water heaters generally need to be cleaned, inspected and disinfected every one and a half to two years. You can ask professionals to clean them, or you pYou can carry out disinfection work yourself. People ignore solar power cleaning. For water quality reasons, a large quantity of scale and rust is deposited there. The power and thermal efficiency of solar energy are significantly reduced and more than a third of the energy is wasted.
Due to long-term accumulation of scale, it not only wastes energy, but also creates hidden safety risks. Scale causes uneven heating, causing pipes to burst and pipes to block. the water temperature drops. Solar water heaters will have problems in the water tank after being used for more than two years. There is a layer of water stains. This is because water contains a certain amount of calcium and magnesium salts, such as bicarbonate, carbonate, etc., which also contain sediment and organic matter. These salts undergophysical and chemical changes during the heating process to form scale. like when we boil water with an electric kettle for a long time, we see a layer of water stains. The calcium bicarbonate in the water will break down into insoluble calcium carbonate as the water temperature increases. So clean it regularly.
How to clean a solar water heater
1. Remove the vacuum tube, handle it gently and do not break it;
2. Remove the vacuum tube. Empty the tartar.
3. Clean the scale on the inner wall of the solar vacuum tube. This requires the use of a special acid descaler. .
Pour in acidic scale remover and soak for about ten minutes, then use a brush to pull back and forth to remove remaining scale, then rinse twice with clear water. Note: It is best to pore gloves when cleaning to avoid burning or scalding the skin! It is best to use the water the day before, disassemble and wash it the next morning, repair it before sunrise, and then refill it again without affecting the day's use.
4. The solar water heater should be cleaned about once a year, because there will be more scale on the inner wall of the vacuum tube and the density of the scale is much larger than that of water, so it will accumulate in a vacuum tube.
How to clean solar pipes
To clean the solar water heater, you need to remove the pipe, drain the water and then rinse.
1. When cleaning the solar water heater, first slowly remove all the sealing rings, then disassemble the solar tubes one by one. During this step, make sure to wear gloves to avoid scratches. your hands.
2. After removing the pipe, vYou will find that a lot of water will flow out of the pipe. Empty the water from the solar pipe.
3. When dismantling solar pipes, especially those that have rusted for a long time, it is more laborious. Be sure to remove them carefully and slowly. force to avoid scratches.
4. After emptying the water into the solar pipe, rinse it with clean water. Because the water in the solar pipe is waste water and dirt, we need to reuse it. Rinse with plenty of water.
5. After flushing for a while, put a little detergent diluent on the top of the solar pipe, then install it into the solar pipe. At this point, simply rinse it with clean water.
Methods to reduce scale in solar water heaters:
1. The hot water in the bucket should be refilled in time after use in summer, which can reduce the temperature of the water in the bucket.
2. Use warm wateras much as possible in summer, then fill it with tap water in time to lower the water temperature in the bucket.
3. Cover the glass tube with a sunscreen net to reduce sun exposure.
4. Install a water temperature gauge to easily check the water temperature and water level in the bucket. Try to keep the water temperature in the bucket below 80 degrees, preferably between 60 and 70 degrees, so that there is no scale.
To clean the solar tubes, we can follow the following steps: first pour the water into the collector tube, and at the same time pour out the scale. Remove one, shake it lightly, and pour it in while it's still hot. Then pour water with a spoon, shake and rinse several times until clean.
Remove the rubber sealing ring inside the water tank mouth. After theOnce you have all removed them, rinse them with water, especially on the inside, to ensure a good seal with the collection tube. Clean the scale from the water tank. Use a curved tool to remove large areas of tartar, then rinse with plenty of water.
Finally install the rubber seal. Use your hands to facilitate installation from the two holes and place it on the stainless steel edge of the water tank. After installing the heat collecting tube, prepare a little detergent diluent, rinse the top of the solar tube with water, apply a little detergent solution, and slowly push the top into the water tank. Be careful not to damage the lower vacuum glass nozzle.
After using a solar water heater for a period of time, a large amount of scale will be produced, which is related to water quality. Once scale is generated, thermal efficiency is significantly reduced. The waterwas heating up very quickly, but now the water temperature no longer increases because the scale forms an insulating layer between the inner wall of the heating tube and the water. , blocking heat transfer. After using ordinary solar water heater for 3-4 years, the hot water temperature drops significantly, the sensor fails, the electric heating tube ruptures, and the hot water turns yellow and mixes. The reason is due to tartar. This is because a small amount of sediment and impurities in tap water are deposited inside the vacuum tube and inner tank; the solubility of calcium and magnesium salts in water decreases during heating, forming crystalline precipitates and precipitating water in the solar water heater; heats up slowly and a large number of bacteria reproduce and form dirt with scale. If you want to clean it yourself at home, you need to prepare a thimblesolar scaler for household appliances and some common tools needed.
