[Digital Meter] 72: 3 items of measuring device research
On December 24th, 11th, the Association of Smart Manufacturing Association of China Association for Science and Technology established a joint conference in Beijing. The consortium consists of China Mechanical Engineering Society, China Instrument and Control Society, China Automotive Engineering Society, China Electrotechnical Society, and China Electronics Association. Family Society co-sponsored.
The establishment of the Institute of Intelligent Manufacturing Association will help improve the technological innovation capability and core competitiveness of China's smart manufacturing industry, and promote the effective integration of universities and research institutes.
December 11-20, according to the data on market price changes of major production materials in the latest circulation areas (December 11-20, 2016), the prices of rebars used to manufacture the instrument's raw materials rose, and the prices of electrolytic copper and aluminum ingots. In decline.
The raw material of manufacturing instrumentation as the upstream industry of the instrument industry, its price trend will directly affect the development of the instrument market.
3 recently, Zhejiang Institute of Metrology, "Study of conductive liquid medium thermal conductivity testing device", "Study of portable blackbody metrology furnace based on semiconductor technology", "Study of portable temperature and humidity standard device based on flow separation method" and other 3 items Scientific research projects passed the acceptance of the Provincial Bureau of Quality Supervision.
Comments The research and development of these metrology device research projects facilitates on-site inspections that are more efficient and convenient, and at the same time improve the laboratory's on-line inspection and calibration capabilities.
3200 households On December 26th, the reporter learned from the Yibin Power Supply Company of the Sichuan Provincial Power Company of the State Grid that the "multiple-in-one-in-one" collection and construction work was successfully piloted in Nanxi District, Yibin, China. It completed the first time the "electricity meter, water meter, gas meter, and heat meter. "Multiple forms combined to transform 3,200 households.
Comments on the "multiple-in-one" collection and construction work can provide customers and enterprises with more convenient services, and at the same time promote the rapid development of "smart cities".
The 12 annual "Committee for Annual Meetings and Regulations of the Force Hardness Measurement Technical Committee 2016" was successfully held in Yubei District of Chongqing on December 15th. The "Measurement System for Measuring Force (<1MN)" was conducted in the meeting. Tables and other 12-item verification procedures for force values ​​in the area of ​​hardness.
Review The use of mechanical metrology instruments has a wide range of uses and many applications. It has an important role in daily mechanical calculations and in-depth studies.

A drilling and bolting machine consists of one, two or three rock drill carriages, sometimes a platform, which the miner stands on to load the holes with explosives, clear the face of the tunnel or else. The carriages are bolted onto the chassis, which supports also the miners cabin and of course the engine. Modern drilling jumbos are relatively large, there are however smaller ones for use in cramped conditions. Whereas modern jumbos usually fitted with rubber tyres and diesel-powered, there are also exist variants with steel wheels, to ride on rails and even single carriage sled-mounted ones. Electric power is also common, historic jumbos were powered by compressed air. Electricity and compressed air produce no exhaust gases, which is preferable if work is done in smaller tunnels where good ventilation is difficult.
