Agents how to choose parts of
80% of sales of s rely on accessories to protect, the option is also very important.
In the fierce market competition, how to create maximum profit for their development, as this is solar energy companies are seriously considering. At present, the rapid rise in the solar industry, there are about 4,000 large and small manufacturers, while the really big manufacturers also only a few dozen. Choose what kind of factory, agent what kind of brand, which is very important for solar dealers. Strength of large manufacturers, after-sale protection, but also hard to protect the dealer market development, development prospects, but the price is relatively high. However, this also depends on the local level of consumption, if the low level of local consumption, large selection of brand customer base is small, in order to have a big development is quite difficult, unless there is a large developer or government support. Large selection of manufacturers of brand is a good medium to do, after-sale protection, the face of middle-class consumers, a large customer base, development potential, could also face a more vast rural market, the development of space is very broad. Only choose the brand, to long-term development. 80% of sales of solar water heaters rely on accessories to protect, the option is also very important.
How to choose solar energy meter?
Solar instrument is the heart of the entire solar water heaters, solar water heater is running Command, solar water, heat, electric heating and other functions controlled by it. If the quality of the solar meter is not reliable, no end of trouble. The original bell solar instrument controller, display with highlights instead. After the 2002 launch of large-screen color LED digital display, full Chinese display running to fill the domestic solar industry in this field instrument blank, causing the solar industry, a major instrument of change.
Solar instrument consists of three parts:
One for the host controller can be divided into semi-automatic, automatic controllers and all intelligent controller. DC and AC automatic controller has two, simple, cheap, the main function: to set the water level, water temperature display, water water full alarm. Automatic control device by a solenoid valve sensor and the host component, the main features include semi-automatic controller, there are automatic Sheung Shui, Sheung Shui, water, regular Sheung Shui, Sheung Shui and low-pressure pipe insulation function, general instrumentation as well as anti running water feature. Whole host intelligent controller with sensors and solenoid valve components, including not only the above functions, as well as intelligent heating, heating time, smart water, regular water supply, power failure memory function, and some instruments have constant water temperature constant level of functionality. Quality of the mold with a host of times in the 30 micron thickness, no varistor, easy to lightning, the electrical wire inside the square is not easy to leakage resulting in serious consequences. Second instrument transformer temperature is too high, easy to burn and explode. Times the chip will lead to procedural confusion, poor immunity, prone to crash.
Two of the probe can be classified according to the material of stainless steel probe and silicone probe. Stainless steel probe of stainless steel jacket heat shrink tubing and thermistor composition. The quality of a probe used it mainly to see the quality of heat-shrinkable tube. Solar water heaters in the annual 5 to 10 months, the water temperature in 80 ? ~ 100 ?, heat-shrinkable tube and plastic tube with the composition of rubber itself volatile, volatile at a high temperature plastic and stainless steel probe tube quality is the fundamental life Once glue or leaking pipes, damaged thermistor probe scrapped, instrument failure occurs. The best thermal resistance with an accuracy of one per cent, self-determined life of the material. Soft silicone sensor is divided into two kinds of silica gel and hard gel sensors. The external silicone sensor is composed of silica gel and activated carbon. The quality of the sensor silica gel and activated carbon depends on the viscosity and sex. The sensor is bad stick and easy to crack, resulting in the probe transmission signal denial or failure. General four-wire stainless steel probe, probe for the two silicone wire.
Three instruments for the solenoid valve by the manufacturer on behalf of the general election, there are only back to the generation of filters, coils inside the standard as well.
How to Select Solar tracer?
The first tracer Raychem Corporation in the United States in the 1950s developed in 1984, China began to widely used in industry, 100 yuan per meter. In 1985, the Science and Technology Commission issued to the development of scientific research institutions file with the tropics, and set Spark Program. 1989 Siping use fluorine rubber research institutes and other polymer materials, the use of chemical technology, successfully developed the first hinge, and further improved, and the level of technology to stay ahead. Self-regulating heating cables are designated as National Torch Project, our research institutes and Siping said Lian Ping, with tropical sea. East China University of conductive plastics used technology developed using light radiation with tropical, but also tell you that the Wuhu tracer. Fluorine rubber stable performance, long life, high prices, conductive plastic to be cheaper.
With tropical works: two parallel wires in the middle of filled polymer conductive plastic or rubber as with the core fluorine, fluorine rubber, plastic or polymer which is the skeleton of the matrix material and filler vectors Qi role of inorganic filler is the current carriers in the conductor insulation the formation of conductive network connectivity, from the current channel effect. When the power is turned on, the current through a wire through them with a wire core to another, and form a loop, with a fever after the core power and maintain the pipeline flow. This conductive plastic or fluorine rubber in the temperature rise, thermal expansion, so that part of the current channel network has gradually broken by the current is reduced, along with the reduced heat, when the temperature rises to a certain extent, the current and temperature are relatively stable . When the temperature decreases, with a core contraction, the current increased temperature, when the temperature rises a range Shiyou stabilized, which is self-limiting heating cables automatically adjust the temperature and the temperature of the principle. From the current market, with tropical allow the solar industry is not satisfied with the quality, we can only follow a large selection of manufacturers of solar products, after-sale guarantee. Super catheter stability, there is a certain Bureau of.
How to choose solar water pipes?
Connect with users of solar water channel, if a problem occurs, it will stealing or water filled camp, the consequences could be disastrous. Solar water used for the glue, the normal grip with three lit a look at two ways to verify. A look: pure color wall thickness; two grip: 30 cm with water several times 180 degrees of grip, grip at times on the white water, good water on the grip at the shiny; three lit: with 50 cm water in a circular motion on the gas stove burn center, when the water-like transparent burning, the hands turn a few laps the opposite direction, let go to recovery, his hands pulling the middle outside, round the more open the more homogeneous, the greater the sound off the better the quality.
