Abstract

The invention can be used as a diagnostic tool for internal combustion engines for detecting wear products in oil. The purpose of the invention — to increase the information content by taking into account magnetic and non-magnetic particles — is achieved by making the magnet 3 movable, through the filter 5 and the filter housing 6, matched with the inner side surface of the housing. Pressing the rod 10 between the filter 5 and the magnet 4 creates a gap, the value of which depends on the volume of soil particles 21 accumulating on the filter 5. This value is controlled by the axial movement indicator 16. 1.il (L years with N4 00 to

The invention relates to the diagnosis of internal combustion engines, in particular, to devices for detecting the destruction products of its parts in engine oil, and can also be used in self-cleaning filters.

The aim of the invention is to increase the information content by taking into account the accumulated particles in the total volume, as well as taking into account, in addition to magnetic particles and non-magnetic soils.

In the drawing. Schematically depicted signaling the presence of chips in the oil section.

The detector contains a cylindrical body 1 and a bottom 2, made of conductive material and connected by threads, located in case 1 ring ferrite upper 3 and bottom 4 magnets. The magnet 3 is rigidly connected to the filter 5, which through the metal case 6 of the filter is mated with the inner side surface of the case 1. The magnet 3, made in the form of a screw 7 and a washer 8, is rigidly connected with pin 10 through contact 9 made of an insulating material. The filter housing 6 is spring-loaded when the spring 11 is fitted. The bottom 2 is connected by means of thread 12 to a conductive cup 13, to the bottom of which pin 15 is connected through the insulating sleeve 14, which is connected by means of threads to the axial displacement indicator 16 at risk 17. The alarm device contains an inlet 1.8 and an outlet 19 nozzles. Between the contact plate 8 of the contact 7 and the filter housing 6 there is an annular surface 20 on which the ferromagnetic soil particles 21 are deposited. The latter also accumulate on the magnet 4. The electric wires 22 through the insulator 23 are connected to the power supply 24 and the signal lights 25 and 26. The arrows in the drawing indicate the direction of oil movement.

The device works as follows.

Before starting work, contact 15 is adjusted so that when the rod 10 is pressed to contact the filter 5 with the magnet 4 in the complete absence of contaminants, the contact 15 would connect with the screw 7, and the light 26 lights up, as the electrical circuit is connected

Oil goes through the internal cavity of the cup 13, filter 5 through the inlet 18 to 5 through the outlet of the outlet 19. When the alarm device is working, ferromagnetic particles impurities are deposited on the surface 20

 the magnet 3 and accumulate on the filter 5, and not only ferromagnetic particles accumulate, but all particles whose dimensions exceed the cell size of filter 5. When the conductive ferromagnetic particles block the surface 20, the lamp 25 lights up as the electrical circuit of the filter 6 - body 1 - bottom 2 - glass 3 - light bulb

Before stopping down, ferromagnetic particles from magnet 3 and filter 5 jump to magnet 4, which has a higher magnetization, while ferromagnetic particles of contaminants accumulate on magnet 4. When pressing the rod 10 down until it stops due to the presence of particles 21 soils on magnet 4 and particles of soils on filter 5 creates a certain gap between filter 5 and magnet 4. By the size of this gap at any time, you can determine the degree of pollution of filter 5. Dp this index of axial displacement

Thus, the detector allows you to control the penetration of the conductive ferromagnetic particles of 50 gr in time with the surface 20 of the magnet 3, to clean this surface and the filter 5 without dismantling the detector by pressing on the rod 10, the gap between

In addition, any types of particles, both non-magnetic and non-conductive, are controlled by the ingress into the oil system. Under pressure of the oil, after switching on the system, the 10-t IOt, together with the filter 5, move upward, squeezing the bushes 11, Mto allows for the height of the rod protruding from the housing 1 to conclude that the filter element is clogged. with constant oil pressure in the system.
