Remove the first tube from the solar side first, as it has a larger contact area and is less likely to damage the vacuum tube.
The specific steps are as follows:
1. Hold the upper and middle parts of the vacuum tube with both hands and twist it left and right. Note that older solar panels work harder.
2. While rotating, push up to remove the vacuum tube from the base.
3. Lift the lower end of the vacuum tube, twist it and remove it. That's all. If it is difficult to turn, use a syringe to draw up the dishwashing liquid and inject it into the rubber fitting between the vacuum tube and the barrel.
Detailed information
The points to note when disassembling solar vacuum tubes are:
1. First of all, it is recommended to do the following: you choose to disassemble in the dark during the day, in the morning or on the eveningr, because you need to drain all the hot water from the solar water heater before dismantling it (to avoid getting burned by the hot water seeping in when dismantling the pipe).
2. When disassembling, it is recommended to use water soaked in detergent or washing powder to lubricate the vacuum tube. At the same time, pay attention to the angle of the vacuum tube and avoid it. pull the angle to prevent the vacuum tube from breaking.
3. After the vacuum tube is disassembled, it must be packed in special polyester foam compartments and placed in special cartons to avoid shock during transportation.
The solar vacuum tube is the heart of the solar water heater. Its structure is like an elongated thermos bottle. There is a void between the inner and outer layers. The surface of the inner glass tube is covered. a spectrum-selective absorption coating using a special layer to further absorb radiation energysolar.

How to disassemble the solar vacuum tube
< p>When disassembling, use water soaked in detergent or washing powder to lubricate the vacuum tube. At the same time, pay attention to the angle of the vacuum tube and pull it gently to prevent the vacuum tube from bursting and injury. After disassembling the vacuum tube, use special polyester foam compartments. Install it and place it in a special carton to avoid shock during transportation. It is best to choose a cloudy day first, in the morning or evening, because you need to empty everything. hot water from the solar water heater before disassembly (to avoid being damaged when disassembling the pipe). Burns caused by hot water leakage)Disassembly method:
Use water. soaked in dish soap or laundry detergent to lubricate the connection between the vacuum tube and the water tank,then turn left and right and push it slightly, then remove the other end of the vacuum tube from the circlip and gently pull the vacuum tube out of the water tank.
What should be paid attention to when disassembling solar vacuum tubes:
1. First of all, it is better to choose a cloudy day, morning or early morning. evening for disassembly, because before disassembly, You must first drain all the hot water from the solar water heater (to avoid getting burned by the hot water that seeps in when disassembling the pipe
2. Use water soaked in detergent or lye when disassembling to lubricate the vacuum tube. At the same time, pay attention to the angle of the vacuum tube. It should be pulled smoothly and avoid. cross each other.Pull hard at an angle to prevent the vacuum tube from bursting and hurting people
After the vacuum tube is disassembled, it should be packed in special foam compartments; ofpolyester and placed in a special cardboard to avoid shocks. during the transport.
Working principle of solar water heater:
The solar water heater converts solar energy into thermal energy, heating water at low high temperature temperature to satisfy people. of hot water in daily life and production.
Solar water heaters are divided into vacuum tube solar water heaters and flat plate solar water heaters based on their structural shapes. Evacuated tube solar water heaters are the leading ones, accounting for 95% of the domestic market share.
Home evacuated tube solar water heaters are composed of heat collecting tubes, water storage tanks, brackets and other related accessories. The conversion of solar energy into thermal energy mainly relies on heat collecting tubes. The heat collector tubeuses the principle of hot water floating up and cold water going down to cause water microcirculation to achieve the required hot water.
