[China Instrument Network Instrument R&D] A few days ago, the Ministry of Education organized a group of experts led by academician Du Shanyi to carry out preliminary acceptance of the project “Development and Application of Materials Micro-Mechanical Performance Testing Instruments†undertaken by Jilin University for major national scientific instrument equipment development. .
Sun Youhong, vice president of Jilin University, Ren Luquan, chief scientist of the project and academician of the Chinese Academy of Sciences, the person in charge of the relevant functional departments in the school and the person in charge of the project participating units attended the acceptance meeting. The meeting was chaired by Wang Fangzhan, Deputy Director of the Basic Division of the Science and Technology Department of the Ministry of Education.
In his speech, Sun Youhong stated that the in-situ tester for micro-mechanical properties of materials in the multi-load and multi-physics environment developed by the project has achieved major breakthroughs and has broad application prospects, providing strong technical support for the development of the country's strategic emerging industries. It is hoped that the project team will do a good job in follow-up research and development and strive to produce more excellent results.
At the meeting, Prof. Lunquan Quan, technical director of the project, Professor Zhao Hongwei, and the person in charge of each project carried out work reports. The expert group conducted inquiries, on-the-spot examinations, and discussion of the project and agreed that the project successfully developed an in-situ tester for micro-mechanical properties of materials under a multi-load and multi-physics environment with independent intellectual property rights in China and associated analysis and processing software. International zero breakthrough of this kind of instrument. The R&D equipment has been tested, developed and expanded in advanced steel, aluminum alloy, high-end equipment manufacturing, aerospace and other fields; key technologies/instruments for R&D have been applied and promoted.
The project achievements have provided technical support for major national science and technology needs, such as high-tech numerical control equipment, large aircrafts, manned spaceflights and other national major science and technology projects, and national key research and development plans, as well as strategic emerging industries such as new materials and high-end equipment manufacturing. The project satisfactorily completed various tasks as stipulated in the mission statement. Some of the tasks were exceeded and agreed to pass preliminary acceptance.
It is reported that the project of "Development and Application of Micromechanical Properties of In-situ Testing Instruments for Materials" of the National Major Scientific Instruments and Equipment Development Project was approved by the Ministry of Science and Technology in 2012. The mission-taking units include Jilin University, Peking University, Beijing University of Technology, and the General Iron and Steel Research Institute. Institute, Chengdu Aircraft Industry (Group) Co., Ltd., Northeast Light Alloy Co., Ltd., Zhongjie Machine Tool Co., Ltd., Yangzhou Jiemai Forging Machinery Co., Ltd., and SINOMACH Changchun Machinery Science Research Institute Co., Ltd.

Gamma 99% Purity Medical Oxygen Generator is used to produce oxygen with purity up to 99%. It is the combination of standard 93% purity Oxygen Generator with one oxygen purifier. Detailed parts combination is as below:
Air Compressor
Function: provide
compressed air source for the PSA oxygen generator, the flow and
pressure are to be decided by the desired oxygen flow rate, purity,
outlet pressure. As it is the air source of whole system, the
performance of air compressor has remarkable influence to the whole
oxygen generator system. Air source must be stable, sufficient with
pressure not less than 7.5 bars.
Compressed air treatment part
Function: get rid of
water, oil, impurities in compressed air coming from the air compressor,
providing clean, dry, oil-free compressed air for the PSA oxygen
generation part. It includes 3 filters, 1 refrigerated dryer and 1
activated carbon oil remover. After treatment, dew point of compressed
air can reach -20 degree (normal pressure) , dust content is not larger
than 0.01mg/m3, solid particles diameter is not larger than 0.01μ, oil mist content is not more than 0.003mg/m3.
Air tank
Air tank function:
It quickly increases the pressure of adsorber;
It also stores gas for air compressor, buffers system pressure;
PSA oxygen generation part
Function:
It is the key part of
whole system. In this part, the oxygen is separated from compressed air,
sent to buffer tank as produced gas. Nitrogen, carbon dioxide,
argon,etc are discharge from muffler as exhausted gases. The efficiency
of this machine is mainly decided by adsorption tower structure, air
distribution structure, molecular molecular sieve performance, process
flow, etc.
O2 buffer tank
O2 buffer tank function:
It balances pressure fluctuation, ensure stable oxygen supply;
With oxygen re-blowing system, the O2 buffer tank can also quickly increases the pressure of adsorption towers.
PSA oxygen storage tank 1
Function:
To help the performance of oxygen purifier, one oxygen storage tank is supplied.
Oxygen purifier
Function:
This is another key part for the high purity oxygen generator. After its treatment, 99% purity oxygen is achieved.
Oxygen storage tank 2
Function:
After treatment of
oxygen purifier, the 98% purity oxygen has very low pressure, for
getting higher pressure, another oxygen storage tank is supplied.
Oxygen Compressor
Function:
As the 99% purity oxygen pressure is very slow, to get 150 bars pressure, one oxygen compressor is needed.
Oxygen filling station
Function
It is used to fill the high pressure oxygen into cylinders for storage or selling.
High purity Medical Oxygen Generator specification:
Oxygen purity: 99%
Oxygen flow rate: 5-100 Nm3/Hr
Oxygen outlet perssure: 5-200 bars99% Purity Medical Oxygen Generator
99% Purity Medical Oxygen Generator,Hospital Oxygen Generators,Cylinder Filling Oxygen Generators
