how to choose
Instrument selection adopts the principle of combining advancedness and applicability. Attention should be paid to the characteristics and functions of the product to meet the requirements of production stability, reliability and safety, and the performance-price ratio is reasonable. The principle of multiple detectors is to consider different detectors with different relative densities and different protection radii. In order to prevent a blind spot at the intersection of the two detectors in the protected area, there is a 1m overlap. The first two conditions are easy to determine. The first condition is explosion detection, the second condition is poison detection, and the third condition is that someone has leaked the poison detection. For example, no one has leaked the explosion detection. In some production enterprises, field instruments are the main means of production process detection, such as field temperature display, pressure display, liquid level display and so on. Combustible gas detection and alarm require only an alarm with indication and alarm functions. As with other analytical instruments, toxic and harmful gas detectors are determined by relative comparison.
Failure detection and analysis: The displayed value in the SUI may be a large amount of material leakage, circuit failure, damage to detection components, detectors entering stolen goods or droplets. Failure inspection and analysis: The first probe inspection was normal, and no flammable gas leaked. After the second inspection, it was found that the secondary instrument was poorly grounded and there was a virtual connection phenomenon, which caused the secondary instrument alarm. The alarm sound is continuous, and the alarm blinks. Check whether the instrument is in fresh air environment. Is the power supply normal? Is the alarm point set correctly? Is the connection between the sensor and the motherboard firm and reliable? Adjust the zero potentiometer to display the alarm Click the reading below, observe the alarm sound, and indicate whether the ****** stopped; if the alarm sound disappears, the ****** will go out, then the meter is normal; if not, you should send a professional to keep it high at any time Or very low readings to calibrate the instrument. Regular calibration of the instrument is the key to ensuring the accuracy of the measurement. For domestic flammable gas alarms should be installed near the stove near the kitchen gas pipeline.

With the adjustment of the international economic structure and the development of a low-carbon economy, the world is entering a new energy transition period. A few days ago, the European Commission adopted a strategic long-term vision called "giving everyone a clean planet" to build a prosperous, modern, competitive, and climate-neutral economy by 2050. This shows that the demand for the global new energy market will continue to grow steadily. Photovoltaic power generation has become an industry with development potential among all renewable energy sources due to its unlimited source and unlimited application methods. China's photovoltaic industry is currently in a critical period of accelerated transition from incomplete marketization that requires subsidies to full marketization that does not require subsidies. The introduction of the 531 New Deal this year will undoubtedly have a huge impact on the domestic photovoltaic industry. The new policy has played a certain role in regulating the market, purifying the market environment; the cost of photovoltaic modules has been reduced, and first-tier manufacturers have accelerated technological innovation. However, the introduction of the New Deal has also caused the domestic market to shrink suddenly, and even caused a loss of 100 billion yuan in market value of the photovoltaic industry. At the same time, affected by the adjustment of the domestic photovoltaic market policy, many photovoltaic companies have begun to regain the development of the international market. In fact, China's photovoltaic industry has a good gene for the international market. At the beginning of development, the capital, talents, equipment, and demand of China's photovoltaic industry all came from the international market, but after the cold winter of 2012, plus the subsequent "double anti" (anti-subsidy, anti-dumping) measures launched by European and American countries against Chinese photovoltaic companies. ), Leading to a sharp decline in the performance of many Chinese photovoltaic companies listed in the United States. At the same time, the huge domestic market opportunities have suddenly started, and there have been a lot of government subsidies, which has caused Chinese photovoltaic companies to shift their development focus to the domestic market. The overall competitiveness of the international market has shrunk-the number of Chinese PV module exports and production capacity At one time, the proportion dropped from more than 95% in 2011 to about 30%. However, the strength of China's photovoltaic industry continues to occupy an international position. According to a report issued by the International Energy Agency (IEA), China ’s new and cumulative installed capacity of photovoltaics in the market in 2017 are both in the market position, with an additional installed capacity of 53GW, accounting for the world ’s total new installed capacity. As of the end of 2017, China's cumulative installed capacity of photovoltaics was 131GW, accounting for the total cumulative installed capacity of photovoltaics worldwide. From 2012 to 2017, the cost of installing distributed solar photovoltaic power generation systems worldwide fell by 55% per kilowatt, of which the cost of photovoltaics in China's industrial and commercial scale fell significantly. In 2017, China's photovoltaic industry accounted for 2/3 of the global photovoltaic industry, reaching 3.4 million. In terms of competition in the international market, the development of international photovoltaic companies has been troubled. SolarWorld, a European photovoltaic company, and Suniva, one of the U.S. module companies, have successively announced their application for bankruptcy protection.In the global technology industry, SunPower has laid off employees and shut down some Philippine production lines, and Panasonic has also closed down some cell production lines and reorganized its photovoltaic business. When the market structure changes, Chinese photovoltaic companies should seize the opportunity, adjust their own international development strategies, effectively combine domestic and international markets, and steadily improve the competitiveness of the international market. At the same time, we need to pay attention to several points: First, the scale of China's photovoltaic industry is huge. The global production scale of all links in the industry chain accounted for over 50% of the world's total, and continued to maintain the world's number one position. In addition, the intelligent manufacturing gradually implemented in the country is also at a level in the world. However, there are still shortcomings in photovoltaic high-end battery technology, equipment, and materials, including key equipment required for N-type, black silicon, PERC technology, etc., still rely on imports to a certain extent, and the capacity of intelligent factory system integration still needs to be improved. Second, due to the high homogeneity of Chinese photovoltaic products, price wars may be triggered when companies develop international markets. In 2017, China's total exports of photovoltaic products were US $ 100 million, a year-on-year increase, but the prices of product exports continued to decline. Chinese photovoltaic companies need to change the business philosophy of the industrial economy period and shift to the strategic thinking of "cooperation and symbiosis" in order to improve the overall production efficiency and ability to resist risks of the Chinese photovoltaic industry, so as to occupy a competitive advantage in the international market and improve internationalization. Management capacity. Third, at present, although China's photovoltaic industry ranks globally in terms of processing and manufacturing, its competitiveness in the global photovoltaic application market is not enough. With the gradual convergence of technologies such as the Internet of Things and regional blocks to the Chinese photovoltaic industry, there are more and more scenarios in which photovoltaics can choose to directly apply. Combining the development of the photovoltaic industry with China's industrialization development path, truly applying the characteristics of photovoltaic power generation with high efficiency, environmental protection and energy saving to real life, improving the domestic industrial chain, integrating the domestic market with foreign markets, and promoting the industry's international competitiveness Enhancements. Fourth, photovoltaic companies need to have a strategic vision when opening up the international market. We must not only focus on product production and sales markets in the international market, but also focus on talent, R & D, and investment and financing markets, so as to establish a global photovoltaic industry supply chain.
