1. Installation of the pipeline
To prevent the backflow of hot water, a non-return valve must be installed in the pipeline. The check valve is installed where the hot water pipe is connected to the tap water and is installed in a vertical direction to ensure that the arrow is upwards, in the same direction as the tap water. Block the exhaust vent. All pipes must be effectively secured. Choose a suitable size hose clamp, and the distance between hose clamps should not exceed 1 meter. The ball valve should be installed at the junction of the solar hot water system pipe and tap water.
2. Pipeline insulation
It is recommended to use high-quality polyurethane, rubber or polyethylene materials (wall thickness 20-50 mm) as insulation materials, which are easy to install and dismantle . and do not requirewater absorption, low thermal conductivity and good dimensional stability. After testing the pipes with water, the heating cables are installed and then insulated.
3. Antifreeze of pipes
In areas with low temperatures and easy freezing, closed balcony pipes should be added to increase the antifreeze properties of the heating cables. This heating cable has the characteristics of anti-aging, self-limiting temperature, fast start-up speed, low operating cost, easy installation and maintenance and 'strong thermal stability.
Detailed information
Daily maintenance of solar water heaters:
1 When installing a water heater solar, there may be dust. or dust in the water pipe If there is an oily smell, you can open the faucet to remove debris before using it for the firsttimes.
2. The water stored in the solar water heater should be discharged regularly depending on local water quality conditions. Drain time can be selected in the morning when the sensor temperature is lower.
3. The surface of the solar water heater should be wiped regularly depending on the amount of dust in the area. It can be cleaned when it rains. Keeping the water heater surface clean can get higher heat. collection efficiency.
4. When hot water is not used for several consecutive sunny days, the hot water temperature will be very high. When using the solar water heater, please turn on the cold water first, then turn on the cold water. hot water to avoid burns.
The solar water heater is an environmentally friendly and energy-saving device, but during long-term use, the pipes may become clogged. If he is notcleaned in time, it will affect the normal use of the solar water heater. Here are some methods to unclog solar water heater pipes, which can help you solve this problem.
1. Free dredging method
Free dredging method refers to the use of special hooks or thin curved rattan sticks, bamboo sticks and other materials to be inserted from the pipe mouth inward, and then push it by hand, when you encounter an obstacle, gently shake it and move it back and forth to loosen it, then take it out. This method is relatively simple and convenient, but if the blocked material is relatively hard, the unblocking effect may not be very good.
2. Hydraulic unblocking method
The hydraulic unblocking method involves injecting clean water into the pipeline and using pressure to force the pipeline blockage. The construction canbe carried out with sprinklers or other high flow water sources. Normally, you can use a screwdriver to unscrew the drain outlet or ordinary motor outlet, and then pour or spray water into the drain pipe to clear the blockage. This method requires a larger water pressure comparison, more suitable for situations where there is a lot of scum and dirt attached to the pipe after long-term use.
3. Acid and alkali dredging method
Acid and alkali dredging method refers to the use of acid and alkali for cleaning, which has a certain effect. Certain acidic substances such as acetic acid and fruit acid can be used to remove rust and grease from pipes. You can also use alkaline substances such as laundry detergent, etc., and put them down the drain to clean them. However, this method requiressite pay close attention to the selection of materials and the correctness of the cleaning method, otherwise it will affect the service life and health of the pipeline.
4. Vibration dredging method
The vibration dredging method involves first fixing the pipe, then using a hammer or other tools to gently tap the pipe and vibrate it to remove the des solids in the pipe are loose. This method is more suitable for the case where the material in the pipeline is relatively light, but the effect is not very good for relatively hard materials.
In short, there are many methods for unclogging solar water heater pipes. It is better to choose the corresponding method according to the cause and situation of the blockage to avoid secondary damage to the pipes. At the same time, you should also pay attention to the use and maintenance of pipelines, cleaning themer in time and inspect them regularly to keep the pipes clear to prolong the life of the solar water heater.
