With the extensive application of ultra-high pressure technology in China's major equipment manufacturing and emerging industries, the accurate delivery of ultra-high-pressure power values ​​is high-speed locomotive manufacturing, launch vehicles, new nuclear power materials, high pressure fuel injection of engines, and ultra-high pressure food sterilization. High-pressure water cutting and other fields provide reliable measurement technology guarantees. The performance of ultra-high pressure metering instruments puts higher requirements on the accuracy of ultra-high-pressure force values. In order to adapt and promote the application and development of ultra-high pressure technology in emerging fields, it is particularly necessary to improve and perfect the comparison method and device for ultra-high pressure.
The "Ultra-high-pressure National Reference Comparison Method and Device Study" project group uses manganese-manganese pressure gauges as the pressure measurement cores. Through bridge arm resistance matching, a Wheatstone bridge for pressure measurement is constructed and an integrated UHV differential is designed. Pressurized manganin pressure gauge assisted balance device realizes the comparison of ultra-high pressure controlled gapped piston pressure gauge, realizes the function of differential pressure measurement under ultra-high pressure, integrated bridge structure, offsets the effect of temperature drift, and improves The accuracy of differential pressure measurement. The direct balance method was used to compare the controlled-gap piston pressure gauge and the high-pressure free-displacement piston pressure gauge, and the effective area and deformation coefficient of the free deformable piston pressure gauge under zero pressure were reproduced. The project team published 2 related articles and applied for 2 invention patents. After the investigation of science and technology, the “integrated differential pressure manganese copper pressure gauge auxiliary balance device†developed by the project is novel, the research results have reached the international advanced level, and provide a specific experimental complex for the deformation coefficient of the high pressure piston pressure gauge. The current method opens up a unified experimental exploration and technical support for high-pressure pressure values.

According to the size of the crushed material or the crushed material, the mill can be divided into coarse crusher, medium crusher, fine mill and superfine mill. There are four kinds of external forces applied to the solid in the grinding process: pressing, cutting, impact and grinding. Press rolling is mainly used in coarse and medium crushing, suitable for the crushing of hard materials and bulk materials. Shearing is mainly used in fine crushing, suitable for the crushing of ductile materials. Impact is mainly used in medium crushing, fine grinding, ultrafine grinding, suitable for crushing brittle materials. Grinding mainly in fine grinding, ultrafine grinding, suitable for small pieces and fine particles.
The crusher makes use of the high speed relative motion of the movable tooth plate and the fixed tooth plate, so that the crushed object can be crushed by the comprehensive action of tooth impact, friction and the impact between the materials. The crusher is suitable for crushing Chinese herbs, precious medicinal materials, ores and chemical raw materials in small batches in various varieties, alloys, metallurgy, geology, scientific research and other units.
The pulverizer machine has the advantages of simple structure, solid, stable operation and good crushing effect. The pulverized material can be discharged directly from the grinding chamber of the main machine. The particle size can be obtained by replacing the mesh screen with different aperture. The powder collecting chamber adopts the completely closed silencer structure, which can effectively reduce the working noise. In addition the machine is all stainless steel. The inner wall of the casing is machined to achieve smooth surface, which changes the phenomenon of rough inner wall and powder accumulation of the previous models, so that the production of drugs, food, chemical industry and so on is more in line with national standards and meet the requirements of GMP.
