Description

Known methods for.: | Students of ultrahigh pressure through y. and sound conversations.

ilo and the proposed method, from the point of view according to the method of 11llei pressure. 1 m; 1 high-frequency current of the power supply is supplied in the form (. pu.chsiryupp1, its phase-shifted current, with amplitudes of the same sign, at several times. Vibrators. From one source, those converge at the same point.

With a shock of the numerical co-components of the echemical current amp.titude riepeMeLneiin; i of the tip of the pulp during the first half of the period increases but in a sinusoidal law, and in the second one, the exponent decreases to a large slope to pool.

Such hara1; ter.chbeing creates a constant pressure, independent of the times1, but on the pressure of the nerves, 1t |:), sonic soot. These are long-term pr-proporpions. 1S1On the square of the product of the oscillation of oscillations by frequency.

By selecting the appropriate values of amp.chptudy kits and frequency at the focus of the intersecting y,: 1 ultrasonic rays with a shock-pulsating form of ch.caps, you can pressure at nearly ten thousand atmospheres. Mixing the phases of current oscillations in vibrators reduces the pressure pulsation at the focus of ultrasonic beams.

The diagram shows the focusing of oscillations from two acoustic 1X heads, the number of which may be more in accordance with the technical capabilities of their razmepdenn.

Circuits with rectifiers BI and 2 are placed between the chasms of the generator M of the high Mactotbi and the electrodes of piezoquartz plates P; the coil L and the capacitor C. p. 1 are used to receive the phase displacement; Kk oncentratory, uve.1ichuayuschie amplitude of oscillations.

The capacitance C and the resistance RI, in combination with the rectifier B, cause a shock in the electric current circuit with a shock-pulsing formog oscillations in the circuit.

The capacitance Cz, the resistance R2 and the recirculation-iirre.ib 82 perform the analogous role. When focusing the pulsating oscillations, it is necessary to ensure that the karay; 1io ko..ch; biii goes from the vibrators.

In a similar way it is possible to produce surface hardening of the part, 1y.

P I e d e m invention

The method of obtaining ultrahigh pressures by means of ultrasonic cabins, a tl and h and yc g, and with the fact that, as before, the first position of pressure, the first half of the current, is highly charged; in phase, in amplitudes of the same sign, in aesco.chicho vibrato / yuv, the directions of which are similar in each other.
