SU531961A1 - Signaling device of the presence of metal particles in a dielectric liquid medium - Google Patents

Description

the role of the sensor of small metal particles, which is wound by the same wire and made smaller than the main winding, in inter-step pitch. The ends 4 of the main n additional windings removed from the frame to the outside. In the frame, the windows are filled with rolling windows for the passage of a liquid controlled medium into the interturn spaces of the windings (the movement of the liquid medium is shown on fit. 3 arrows).

The block diagram of the detector is made of the following elements connected in an electric circuit of a direct current source (for example, an onboard battery): additional Winding 3 and its generator 6 opening short-circuited coils, amplifier 7, counting part 8, cleaner 9 additional winding and common electric light bulb as well as the main & hank 1 and its generator 10, amplifier 11 interlocked to a common source of light signal — an electric light bulb.

The detector works as follows.

When metal particles get into the liquid dielectric medium controlled by the detector, the particles carried by the liquid medium pass to winding winding 1 and then through the windows 5 of the frame to winding 3 acknowledgments. Through the: winding 1 with large inter-turn wobble small metal particles pass smoothly and do not close its turns. These parts | Zy only close the VIT.ki additional winding 3, inter-turn sh-g. which is calculated on their size in advance. When two adjacent turns of the winding 3 are closed, its generator 6 reacts to the short-circuiting of its turns and gives an electrical signal which, after passing through the amplifier 7, is supplied to the particle counter 8 and the light source a light bulb. At the same time, the signal arrives at the cleaner 9 of the winding 3, which frees its turns from the closure particles. The coils of winding 3 open and

electric lamlochka stops issuing a light signal.

The particle counter 8 registers the presence of small metal particles passing through the system. When a large metal part is dropped into the liquid medium (large chips, a part of a gear tooth, etc.), the latter closes the turns of the main winding 1. In this case, the generator 10 of the winding 1 reacts to the short-circuiting of its turns and gives an electrical signal to amplifier II, from which the amplified signal falls on a common source of light signal - the electric light bulb. The light bulb gives a constant light

signal (even in the case of breaking turns), warning the operator.

The quality of the signal emitted by an electric bulb (flashing light signal and constant) allows the operator to degrade and unambiguously 0 to prevent the actual degree of accident rate of the monitored system.
