The invention relates to spectral analysis and can be used to control the wear of friction pairs of the engine by determining the chemical composition of the investigated substances in flammable liquids.

There is a method of measuring the degree of contamination of the engine oil, designed for the determination of the composition of the products increased wear of friction [1]. The disadvantage of this method is the inefficiency of its use for the control of pollution oil at the initial stage of operation of the engine.

The elimination of this disadvantage can be achieved using way of measuring the degree of contamination of the fluid based on the use of hub microcontaminants in the aerosol containing the controlled spray oil, a heating chamber, a refrigerating chamber, a conduit for draining the condensed liquid, the output channel for the concentrated aerosol [2].

The disadvantage of this method is loss of controlled products, carry out the condensation.

The invention is aimed at ensuring the completeness of the collection of products wear.

This is achieved by the known method of measuring the degree of contamination of the engine oil, based on the use of hub microcontaminants in the aerosol containing the controlled spray oil, a heating chamber, a refrigerating Cham is ru, channel for draining condensed liquid, the output channel for the concentrated aerosol that is associated with the excitation source, an aerosol controlled motor oil get through the jet-centrifugal atomizer and ignite it through a high-voltage flare discharge guiding in plasma-chemical reactor axial axis of the plasma stream for subsequent reuse of aerosol particles, and the obtained solid, liquid and gaseous products after they pass through the refrigerating chamber and the filter control methods of spectral analysis.

The block diagram of the method shown in the drawing, where:

1 - receipt of the aerosol through the jet-centrifugal nozzles [3];

2 - ensuring the ignition of aerosol by high-voltage flare discharge [4];

3 - oxidation of aerosol particles in plasma-chemical reactor [5];

4 - condensation products chemical pyrolysis in a cooling chamber;

5 - the collection of condensate;

6 - weigh-in condensate;

7 - spectral analysis of the condensate [6];

8 - the collection of particles of solid residue on the filter;

9 - ashing filter;

10 - the weighing of the products of digestion;

11 - spectral analysis of the products of digestion [6];

12 - lead gas;

13 - Spectro-analytical control of product composition, carried away by the gas stream.

the manual measurement of the degree of contamination of the motor oil provides its flow through the jet-centrifugal nozzle, forming a stream of aerosol without using a carrier gas, typically used in pneumatic sprayers, which increases the amount of controlled aerosol, reducing the accuracy of microtraces. Using high-voltage flare discharge as ignition flow of aerosol, characterized, for example, arc discharge DC more extensive plasma area, providing heating and ignition of aerosol particles directed to the plasma-chemical reactor, where the implement complete drainage of oil particles. Condensation products of oil collected in the cooling chamber, is subjected to spectral analysis to control, as well as solid particles deposited on the filter, pyrolization in the process of digestion. Passing through the filter gases sent into the pipeline associated with spectral analysis equipment, to control microcontaminants out of the cooling chamber by the flow of exhaust gas.

SUBSTANCE: method of determining colloidal stability of grease is realised from the amount of oil squeezed from the grease, where a cup full of grease with a piston and fitted with an oiled filter together with a set of dry filters is subjected to thermal stabilisation and subsequently held under a load, after which the amount of oil squeezed from the grease into the dry filters is determined. Before thermal stabilisation, a medium boundary is created between the analysed grease and the dry filters by separating them from each other in order to prevent penetration of oil into the dry filters before loading. The amount of oil squeezed from the grease is determined from the displacement of the piston during loading. The invention also discloses a device for realising the said method.

SUBSTANCE: in the method which involves centrifuging a prepared oil solution and subsequent suspension of the obtained residue, deposition takes place in a thin annular layer of the oil solution which rotates together with a rotor. Centrifugation is done once and decantation of the centrifuge effluent is done automatically when the centrifugal rotor stops. In the device which has a housing, an electric motor with a vertical shaft, the rotor is made in form of a reservoir with a removable cover, in which there are two cavities for putting the analysed oil solution, depositing impurities and decantation of the centrifuge effluent. The rotor also has a removable cylindrical insert made from metal foil for collecting residues which undergoes control weighing. The rotor is driven by the shaft of the electric motor through an overrunning centrifugal clutch which automatically connects them in startup and centrifugation mode and also disconnects when the electric drive is switched off, thereby providing smooth free run-out of the rotor with the filtered centrifuge effluent.
