摘要:
An apparatus for cleaning surfaces from substances adhered thereto comprises a multilayer electromagnet coil (1), a source (3) of pulse current, a paramagnetic plate (4) disposed between the surface (5) being cleaned and the electromagnet coil (1). The number n of layers (8) in the coil (1) is within two and five, each such layer having the form of a current-conducting helical bar (7) of rectangular cross section. The layers (8) are arranged in parallel planes and are connected in an aiding connection. With respect to two-layer, three-layer, four-layer, and five-layer electromagnetic coils (1) there is a predetermined dependence of the number W of coil turns (9) in each layer (8) on the optimum number W.sub.1 of turns (9), and the height h of the current-conducting bar (7) on the equivalent depth .DELTA. of penetration on the magnetic field into the metal of the electromagnetic coil (1).
摘要:
The apparatus for vibratory cleaning the surface of an article from foreign matter, comprising at least one exciter (1) of mechanical pulses, including an electromagnetic inductor (2) with a plate (3), a frame (7) and at least one striking surface to be cleaned in an area or areas of the most probable location of the foreign matter, fixedly mounted on the frame (7). Each electromagnetic inductor (2) with the plate (3) closely adjoining this inductor (2) is fixedly mounted on the frame (7).
