Speed-high Centrifuges is commonly used equipment in scientific research production and in the medical and health system. With the development of medical science and technology, the area on molecular biology, genetic engineering, and clinical medicine had a high standard of quality requirements of Centrifuges, that made the centrifuge and centrifugal technology had a very rapid development, and better meet demands in the industrial production, scientific research and medical care.
A. the overview of centrifuge development
The centrifuge is also called the precipitator; there are some types of centrifuge. The separated type centrifuge are used to separation of suspended material in the liquid very quickly, the preparation type large centrifuge is useful concentrate and purification of particle, the analysis low speed centrifuge always be applied to experimental analysis , although centrifuge type is different, the function can be regarded as separation, enrichment, purification, and analysis several categories.
The Centrifuge’s developments were performance in continuous improvement of structure and centrifugal method. Structure improvement firstly embodies in the speed of increase, for six generations , By the initial dozen round to development today's hundreds of thousands round of high-speed centrifuge, drive system of the life from 1000 million to 20 billion RPM; Work time has developed from a few hours to dozens hours or a few days; Centrifugal rotor (turn) the kinds of continuous improvement and increase; Control automation degree enhances unceasingly; The body shape in the direction of the beautiful, practical, miniaturization development; The greatest progress is the centrifugal method is unceasingly rich and development; The centrifuge application scope unceasingly expands.
B. The Centrifuge driving methods had a conversion process. The driving methods Has experienced the hand cranking, electric, Mechanical variable speed, the power of oil pressure and air pressure mechanical variable speed, and frequency conversion motor variable speed methods.
a.to further improve the speed of centrifuges. As a study of Body Science test, the technology request we having super-speed centrifuges appear, and now our country only had production centrifuges of 6,0000(r/min), however, the super-speed centrifuges had 120,000(r/min) in developed countries.b.to improve the method of speed control. The Variable frequency motor and micro computer control technology had used to the centrifuge’s production by some manufacturers. Which controls the rotation speed and temperature and vacuum degree has reached the work state of man-machine dialog monitoring, and had some function of speeding, over current and over temperature alarm ;
c.To extend the work time of centrifugal, get a reliable guarantee on hardware structure, the time can continuous work for a few minutes to 5 hours, up to 99 hours;
d.the improve of centrifuge rotor. Which is performance on the types and materials, due to the increaing of species, more than 10 kinds centrifuge rotor were be made. Can be respectively suitable for separation, purification, preparation and analysis of a variety of occasions，Materials of high strength aluminium alloy developmented titanium alloy, glass fiber reinforced plastic, etc, improved the durability.
e. the application of microcomputer. The technology made the running parameters from few to dozens. and keeping constant of operation conditions; and the operate not only delay, but also operate step by step. It’s implement the program operation convenient; For operation monitoring, judgment, storage, display, simulation calculation and print multi-functional modern management, the more complete the characteristics of centrifuge.C. Conclusion: During of hundred years’ developing and perfecting of centrifuge, no matter what in the scale or standards, it had a satisfactory level. And the highly automated driving and management of operation, greatly convenient for the user, but it had a new demand of centrifuge’s use and development.
The structure of centrifuge and centrifugal analysis method are has reached a high level and large scale, but there are lots of content need to improvement and innovation.
