Abstract
A drive has been developed for a tubular centrifuge having a 10 kW ASTs-10-504 high-frequency electric motor with a synchronous rotation speed of 15,000 rpm. Despite a few demerits, the drive met the basic production requirements; simplicity and reliability of design, admissable rotation speed, and explosion resistance. However, this drive for tubular centrifuges had to be abandoned because experimental prototypes of high-frequency motors were used for the industrial tests and lot production of such motors is not probable in the near future. Industrial tests of a new hydrodynamic drive were performed, and the schematic diagram is shown. The hydrodrive was tested during centrifuge operation with polyester lac. It was found that the hydodynamic drive is distinguished by operational reliability and easy serviceability, holds promise for increased centrifuge speed, ensures smooth start of the centrifuge and satisfactory stability of the rotor rotation speed in the steady regime, reliably protects the motor from overloading and is fully explosion-proof.
