1. First of all, inspection personnel must wear plastic gloves. Since the temperature of the solar hollow tube is relatively high, wear plastic gloves to avoid burning your hands when removing the solar vacuum tube.
2. Before disassembly, apply a little detergent to the contact area between the upper heat collector tube and the bucket. Detergent will increase the softness and reduce its stability. This makes disassembly easier.
3. Hold the vacuum tube with both hands, use force and twist it left and right, once to the left, then to the right. Try several times. Some of the rusty tubes require several turns. turn. Once the vacuum tube can rotate, slowly push it upwards to pop it out.

Individuals must lend atPay attention to the following points when disassembling solar vacuum tubes:
1. It is best to choose a cloudy day, in the morning or evening. for disassembly, because disassembly You must first drain all the hot water from the solar water heater (to avoid getting burned by the hot water leaking in when removing the pipe).
2. When disassembling, it is best 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 bursting.
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.
4. Be patient during the rotating process, don't be impatient, rotate it several times and never use brute force. You not only need to protect the tubesolar, but also pay attention to your own safety. In addition, there is a vacuum sealing mouth at the bottom of the vacuum tube, be careful not to touch it, which will break the air inlet and lose the insulation effect.
How to remove the heating pipe from the solar water heater?
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 fittingd rubber 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 dismantle in the dark during the day, morning or evening, because you need to drain all the hot water from the solar water heater before dismantling (to avoid getting burned by the hot water that seeps in when removing the pipe).
2. When disassembly, it is recommended to use water soaked in detergent or lye to lubricate the vacuum tube, and pay attention to the angle of the vacuum tube should be pulled gently and avoid pulling the angle to prevent the vacuum tube from breaking and causing injury to people.
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 tube solar vacuum 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 energy from solar radiation.

How to remove the heating tube from the solar water heater:
p>1. First of all, it is better to choose a cloudy day, morning or evening for disassembly, because you need to drain all the hot water from the solar water heater before disassembly to avoid hot temperatures. water flows out when the pipe is dismantled. If it is noon at this time, since the water in the vacuum tube has emitted light, the strong sunlight will damage the vacuum tube and shorten its service life.
2. When dismantling, it is pIt is recommended to use water soaked in detergent or lye 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 bursting. After disassembly, the vacuum tube must be packed in special polyester foam compartments and placed in special cartons to avoid shock during transportation.
3. Use water soaked in detergent or washing powder to lubricate the connection between the vacuum tube and the water tank, then turn it left and right and press it in lightly, then remove the other end of the Remove the vacuum tube of the circlip. Carefully remove the vacuum tube from the tank.

Solar water heater leak repair
1. Water tank leak
Solar insulation Water leaks are relatively rare. If upon inspection it is found that the water tank liner is leakingindeed, then you should consider replacing the solar water tank. The quality and age of the water tank coating directly causes the water tank to rust and leak. But in general, the solar seal ring is usually damaged. In this case, just ask the master to come and replace a few silicone solar rings.
2. Water pipe leak
If the water pipe is leaking or the water pipe is leaking, it is because the PPR water pipe or aluminum-plastic pipe has aged after years of wind. and exposure to the sun. This situation It is necessary to replace the solar hot water pipe. A valve leak means a valve failure. In this case, a new solar valve or solenoid valve must be replaced.
3. The solar heating pipe is leaking
If the solar heating pipe is leaking from the electric heating position, it means that the celectric heater is rusted and damaged, and a new gasket or electric heating rod needs to be replaced. Water leakage of the solar vacuum tube is basically caused by the aging of the solar silicone ring, and the vacuum tube needs to be removed and replaced with a new silicone ring. Water leaks from the solar exhaust outlet are usually caused by damaged sensors or meters. In this case, the water temperature and level meter or a new solar meter must be replaced.
