4 stent is not the collapse of support for solar energy;

5, is to protect the pipeline from the outdoor hot water to transfer the security of the home;

6 electrical heating rainy days in a row, solar hot water are not good when the security;

7 safety lock in a fixed roof on solar energy, security is not falling;

8 temperature controller is easy to use automation to achieve control of solar energy.

If you have a professional production and rigorous testing, these problems are avoidable. Solar Energy Industry Alliance

If the electrical heating:

Looked very simple, it is not possible to do wounding leakage, fire.

The requirements of its solar electric water heater is higher than that: the water heater is usually self-limiting temperature of 60 degrees. Solar Energy Industry Alliance

The solar electric heating tubes in the summer to work in the long-term 90-1000 high-temperature, high-temperature chemical reaction to make all kinds become more active, c1 ion in the water and electric wall will occur electrochemical corrosion, rust into iron atoms to form Localized corrosion;

As the impurities in the water heater will control scale, the scale of different density to form a porous, when the electrical heating starts in the local Department micro scale high-temperature, water vapor and air bubbles formed, in a partial vacuum, liquid To a very high speed to add to crack down on metal surfaces, so the surface of metal fatigue due to the impact of crack and peel or perforation, 2012 will be wearing a rust caused by broken belly cut open, leakage of electric wire, live in the water.

Such electric heating are thousands of manufacturers, the market more than 10 million can buy one of the tanks in the security, dare to use it?

To avoid problems in the choice of raw materials, at least to choose "the British 800 Luce," It is a high-temperature alloys, corrosion resistance of the main raw material nickel, chromium levels as high as 33% and 22%. Excellent resistance to chloride stress corrosion cracking capacity, mainly in the petrochemical industry at high temperature.

If the liner: can not see, touch less, a problem most of the trouble, once the entire solar water leakage on the end-of-life, so that not only white Huale Qian, also own a lot of trouble. Solar Energy Industry Alliance

Liner of a potential bright spot:

First: Welding

The easiest is the corrosion of the weld, handled properly, the water leakage.

For example, prior to welding without rubbing alcohol, the Department of welding left a fingerprint or a little oil, containing carbon atoms inside easily with the liner in the chromium atoms react chemically (6 combined with carbon 23 Cr), the formation of chromium depleted zone 90 stainless steel iron, 2-3-year corrosion would be leaking, short-lived machine;

If the use of hand-welding and resistance welding, it is easy to form a welding Xu Han-off, leakage is almost inevitable that the (current welding in the field of common welding technology: welding, resistance welding, and welding by hand, etc.).

Second: The selection

Material at hand, the high-grade stainless steel and stainless steel, solar energy liner material on the market more than 50 kinds of applications, at least, uneven, high-standard materials and specifications for a low price difference between the material several times, if the liner using low-grade material, Play a critical role in the anti-corrosion chromium, low nickel, nickel-free even in the short term it is easy to corrosion leaks;

Stainless steel liner thickness enough, and some only 0.2mm, like a sheet of paper, and is likely to corrosion breakdown;

To avoid these problems, the raw materials to use at least SUS304 stainless steel liner, the thickness of 0.5mm or more, play a critical role in anti-corrosion of 9% nickel, chromium 18%, and its anti-corrosion ability to meet local water quality requirements;

To guarantee the quality of welding, before welding seam on the specific use for cleaning liquid, and finished in polished within 10 minutes, then application of TIG welding process, more than 10 minutes to wipe.

Fixed wire:

Solar energy in the fixed roof, if 2mm-3mm cold galvanized wire, not strength, strong wind and poor, short-term began to rust corrosion, high winds hit fracture easily; if simple fixed in the mine belt, as a result of Lightning with the standard low, strong winds hit the weather, it is easy to fly on from the roof down and hit Mercedes-Benz cars, were injured, who lost the play? This phenomenon throughout the country where there are strong winds have happened.
To avoid these problems, we must adopt high-quality marine grade wire made of safety locks, anti-aging coat of PVC plastic layer, the performance of fixed, long service life.
