Instrumentation industry will see an inflection point in the industrial structure

In recent years, China's instrumentation industry has developed rapidly. The growth rate of production and sales remained above 20%, and the growth rate of exports rose sharply. The first year of the "Twelfth Five-Year Plan" has now come to an end. In the first 10 months, China's instrumentation industry completed a gross industrial output value of 55.117 billion yuan, an increase of 24.73% over the same period of last year. The total output value of instrumentation sales reached 54.116 billion yuan, a year-on-year increase of 26.12% and a negative growth of 0.85%. This shows that China's instrumentation industry still has great development prospects.

The instrumentation industry mainly serves the petrochemical, thermal power, nuclear power, wind power, rail transportation and other fields. The prospects for the development of these industries are closely related to the development prospects of the instrumentation industry. In the National Twelfth Five-Year Plan, many industries have pointed out that the changes in market demand are relatively rapid, the adjustment of product structure is urgent, and the economic development rate is slowing down. However, whether other industries slow down the pace of development will affect the market demand for instrumentation and whether there will be a new turning point in the instrumentation industry. The answer is in fact affirmative. However, this inflection point does not mean that the instrumentation will be declining. On the contrary, the industry will make major adjustments to the industrial structure along with other industrial industries.

With rapid economic and fierce competition, the instrumentation industry has also exposed some of the current problems. We still face the lack of scientific and technological content, poor innovation capabilities, the market is more chaotic, not enough concentration, and lack of strong national major projects. Support.

At present, China is moving toward the ranks of industrialized countries. One of the issues is how to develop the instrumentation industry. China Instrument and Instrument Network pointed out that China's instrumentation industry can follow the requirements of the country's macroeconomic policies and "strengthen innovation, pay close attention to the basics, market orientation, broaden the scope, institutional innovation, optimize the structure, and continue to promote and revitalize the industry." For strategy. The instrumentation industry will target the high-end product market to improve the stability and reliability of products; aim at the country's strategic emerging industries, expand the traditional areas of service into emerging areas; and vigorously strengthen the adjustment of enterprise structure through certain joint In the form of mergers and other forms, we will strive to build a number of leading enterprises; strengthen the continuous advancement and long-term investment in the achieved results, maintain the continuous accumulation of core technologies, and form a mechanism for the sustainable development of the industry.

In this inflection point, the industry will enter into a new phase through adjustment and adjustment. It basically completes the autonomy of typical equipment control systems in petrochemical, thermal power, nuclear power, wind power, rail transit, etc., and basically meets the needs of key areas represented by environmental protection, food and drug safety, and emergency public safety handling.

Main control valve is an important hydraulic parts for an Excavator. It controls the action of the excavator.

The control valve function as follow:

(1) double pump confluent oil supply and increase the speed of moving arm. (only when the arm is raised)
(2) when the bucket is operated separately, double pump stations supply oil to speed up the action speed of the bucket rod.
(3) the motion of the arm is given priority, and the movement of the arm will be given priority when the arm is carried out at the same time as other movements.
(4) rotary priority, rotary and bucket at the same time, rotation will be a priority.
(5) negative flow control, give the main pump a negative flow signal, so that the stem in the middle, the main pump displacement to the minimum.
(6) walking in a straight line, when the excavator moves forward or backward, other actions can be done at the same time, in order to ensure the needs of special working conditions.
(7) the electric sensor can be configured to meet the needs of electronic control.
