China Drying News In 2012, China's machinery industry ended its annual high-speed growth of over 25% from 2000 to 2011. The growth rate of production and sales was between 11% and 13%, and the industry entered a period of moderate growth.
This reporter learned from the press conference held by China Machinery Industry Federation on the 1st. According to Cai Weici, executive vice president of China Machine Co., the total industrial output value and sales value of the machinery industry in 2012 were 18.41 trillion yuan and 18.04 trillion yuan, up 12.64% and 12.54% year-on-year respectively.
“In 2012, the added value of the machinery industry increased by 8.4% year-on-year, an increase of 6.7 percentage points from the previous year, and 1.6 percentage points lower than the average national industrial growth rate for the same period. For the first time in years, it was lower than the average growth rate of national industrial added value.†Cai Weici said This shows that compared with other industrial sectors, the machinery industry faces particularly severe challenges in this round of adjustments.
It is understood that the market demand for machinery products in 2012 was weak. The growth rate of benefits has dropped significantly and profitability has decreased. The foreign trade situation is grim, and the growth rate has fallen sharply.
According to statistics, the total profit of the machinery industry from January to December totaled 1.23 trillion yuan, up only 5.18% year-on-year, and the growth rate has dropped by 15.96 percentage points from the same period of last year. The industry's main business income profit margin fell to 6.81%, lower than the 7% level in 2010 and 2011. The total tax revenue was 655.3 billion yuan, a year-on-year increase of 12.86%; the company's loss was 11.25%, an increase of 2.78 percentage points from the same period of last year.
Cai Weici said that in a comprehensive view, in 2012, the machinery industry realized a modest increase in major economic indicators such as production and sales, and efficiency. At the same time, under the influence of the market forcing mechanism, the company's endogenous resilience has been increasing, and the industry's transformation and upgrading are working hard. The market demand situation in 2013 will be milder than that in 2012. The annual production and sales growth rate is expected to be around 12%, the profit growth rate is around 8%, and the export growth rate is around 8%.
As one of the important members of the SCR system, the Nox sensor consists of a sensor probe and an electronic control unit. They are connected by wire harnesses and are used to measure the concentration of nitrogen oxides and oxygen in the exhaust gas. In practical applications, the probe is installed in the automobile exhaust pipe, and the exhaust gas concentration is fed back to the electronic control unit in the form of voltage through the ceramic chip. The heating temperature of the sensor probe is controlled by electronic control and through a series of signal conditioning, the concentration of Nox and oxygen in the pump is finally determined. The electronic control unit communicates with the vehicle control center (ECU) through CAN, and transmits the measured gas value to the vehicle control center (EUC) in real time, providing a basis for the SCR injection amount, thereby reducing NOx emissions.
Different types of nitrogen oxygen sensor are suitable for different models, and the nitrogen oxide sensor in this category are all suitable for SCANIA.
