Ma Liandi, Research Associate of the Institute of Chemistry, China Institute of Metrology, is the head of the acceptance expert group, Professor Xie Qingji of the College of Chemistry and Chemical Engineering of Hunan Normal University, deputy leader, Professor Fu Ming of Changsha University of Science and Technology, and Bi Junping, chief engineer of Hunan Provincial Environmental Monitoring Center. Wang Yan, director of the Changsha City Environmental Monitoring Station in Hunan Province, highly praised the project and believed that the project team successfully completed the planned tasks with high quality, met the requirements of the assessment indicators, and used project funds in a reasonable manner, agreeing to pass the acceptance check.
Since the implementation of the project in 2013, the research group of the Hunan Institute of Metrology and Standard Materials Research Institute under the auspices of Zhu Xiang, the senior engineer of the director, has worked on three aspects of technical specifications, development of standard materials, and automated measurement and verification devices to monitor the quality of heavy metal water. The establishment of a metrological traceability system laid the technical foundation.
This project has formulated 4 measurement verification regulations in Hunan Province, and formulated one national measurement technical specification as the main drafting unit. Developed a standard substance for calibrating/calibrating cadmium water quality monitoring instruments. Developed an automatic measurement and verification device for water quality on-line monitoring instruments. He has published 4 papers in academic journals, obtained 1 national software copyright, and applied for 1 national invention patent. The results obtained by the project have been promoted and used in environmental protection companies and environmental monitoring agencies and other units, with broad application prospects.

Portable Diesel Electrical Screw Air Compressor

Portable Diesel Screw Air Compressor


A compressor can be used to power a variety of jobs such as inflating tyres or operating a nail gun at home or in a workshop. Portable air compressors are good for light, quick jobs as they tend to have a smaller tank with a handle and wheels to make them easy to movement. The size of the tank will determine how much air is stored and therefore how long it will run so if you are using tools that require a high volume of air for longer, then you should consider a larger tank.


The energy contained in the compressed air can be used for a variety of applications, utilizing the kinetic energy of the air as it is released and the tank depressurizes. When tank pressure reaches its lower limit, the air compressor turns on again and re-pressurizes the tank. An air compressor must be differentiated from a pump because it works for any gas/air, while pumps work on a liquid.


It mainly used in a lot of drilling fields, such as Water Well Drilling Rig in rocky layer,DTH Drilling Rig in rock works,underground jumbo drilling rig,percussion drilling piling rig,Core Drilling Rig in geological investigation and so on.


Our power-driven portable rotary screw air compressors can meet different demands. Several main advantages of our portable compressors include high reliability and adaptable.
