VIBRATORY VISCOSIMETER

摘要

Vibratory viscosimeter that has body, circuit for excitation of vibrations, this has twin electric magnet. Additionally it is equipped with amplifier of excitation of low frequency, control block, electric magnets of control block, phase inverter, second circuit of excitation of vibrations, frequency-selective section that includes two console shafts with cone rigidly fixed at the end of one of its consoles, springs, units for adjustment of rigidity of dynamical system, induction indicators, permanent magnets, power supply source, frequency measuring device and register of controlled parameters, inside the body two partitions are placed, in each of the partitions slide bearings are installed, on the wall of the body between the partitions opening is provided, this is closed with cover, to each circuit of excitation of vibrations additional pair of electric magnets is included, frequency-selective section if connected to circuit of excitation of vibrations through force-transfer ferromagnetic plates that are rigidly and symmetrically fixed on the other console of the shaft in plane of its axis, the shaft is arranged as such that it goes through slide bearings, inside electric magnets of control block springs are installed, each of those is in contact with the end wall of the body and with the end section of two-console shaft, control block is arranged as connected to electric magnet of control block, outputs of induction indicators are arranged as connected to electric magnets in series through amplifier of excitation of low frequency vibrations and phase inverter, outputs of power supply source are connected to electric magnets of control block through control block, with frequency measuring device and register of controlled parameters, at that to the free end of one shaft cone is fixed by the top, and on the other shaft the cone is fixed to console of the shaft in its cavity, the cones are arranged as such that they go one to another, the cones are in contact one with another with the inner and the outer surfaces, respectively, and the cavity between the partitions of the body is made tight.
