Development of a high-speed table centrifuge with pneumatic drive

The article contains the formulation and solution of the problem of rotor dynamics using the laboratory microcentrifuge as an example. The aim of the work was to develop a high-speed table centrifuge with improved technical parameters. This paper considers the reasons for the appearance of the added imbalance and its negative effect on the operation of the microcentrifuge. A numerical simulation of the stressed-deformed state of the rotor was conduct, and a conclusion about its strength characteristics was made on the basis of design loads. There was presented the rationale of the choice of material for the manufacture of rotor. There was designed the microcentrifuge drive – pneumatic turbine. An optimization and development of geometry of a microcentrifuge’s rotor were carried out. There was produced a prototype of a laboratory pneumatic centrifuge for clinical diagnostic studies.
