Description

one

The invention relates to the field of mechanical engineering, repair and operation of hydraulic machines and equipment, in particular, to centrifuges for monitoring the purity of the working fluids of hydraulic systems, oils and process fluids under operating and repair conditions.

Centrifuges for separating the solid phase of suspensions, consisting of a frame, a rotor with holders for cylindrical or sector forms of ClJ, and also laboratory centrifuges with a rotor having radial partitions with inclined nests and a sample receiver of the analyzed liquid L2 3 are known.

These centrifuges have surfaces on which the deposition of fine impurities occurs, which are located at an angle to the direction of the centrifugal force. Under the action of adhesion forces and electric (SIL impurities are held on the surfaces during the whole centrifugation process and it is difficult to determine their concentration in the liquid.

Closest to the proposed technical entity is a centrifuge for analyzing the contamination of a liquid, comprising a housing, a rotor, including a disk with brackets, in which conical cups for the analyzed liquid are fixed, equipped with caps and capillary tubes with a scale of 3. a fine layer of soil particles on the conical surfaces of the cups during the entire sample processing process. This makes it difficult to determine the concentration of fine impurities in a liquid, since some of the contaminants do not enter the capillary tubes, but remain on the conical surfaces of the glasses.

The purpose of the invention is to increase the degree of solid particles in the liquid.

The goal is achieved by the following: in a centrifuge for analyzing the contamination of a fluid, comprising a housing, a rotor, including a disk with arms, in which conical cups for the analyzed fluid are fixed, fitted with caps and capillary tubes from a scale 0824912

at least two plates bent at a right angle are radially fixed on the bottom of the case, the glasses are fixed in hinge brackets5. However, they are associated with drains placed in guide bushings mounted in the rotor disk, while plastics are also attached to the ends of the racks located under the disk.

15 arrow A in FIG. 2

The centrifuge includes a housing 1, a rotor, which includes a disk 2 with brackets 3, in which glasses 5 for the analyzed liquid are fixed with hinges 4, equipped with pockets 6 and capillary tubes 7 with a scale, Krishki 6 cups 5 are fixed in holders 8 brackets 9 and are associated with racks 10 placed 25 in guide bushings 11 mounted in the rotor disk 2. The brackets 9 are connected to the disk 2 through elastic pads 12, which allow the cups 5 to perform vertical directional oscillations about the axes 13 of the hinges A. At the bottom 14 of the housing 1, at least two plates bent at a right angle are radially fixed located under the rotor disk 2, also

5, the plates 16 are fixed. Between the plates 15 and 16, there is a gap varying circumferentially from ACO to create alternating pressure under the plates 16 as the rotor rotates. A ring 17 is attached to the disc 2 of the rotor, which overlaps the height of the curved plates 15, to create an overpressure in the under-rotor space.

The centrifuge works as follows.

The cone glass 5 filled with the analyzed liquid, closed. the crank 6 and the stopper 18 is installed in the socket of the hinge 4 and fixed in the holder 8. The rotor is driven into rotation and in the cavity between the rotor disk 2, the bottom 14 of the housing 1 with the curved plates 15 and the ring

55 17 air circulation and excess pressure are created under the surface of the plates 16 mounted at an angle to the bottom 14 of the housing 1, for example, 12-20. The curved plates 15 create an uneven pressure perceived by the plates 16, as the gap between them around the circumference changes. As a result, when the rotor rotates the plate 16 is brought into oscillatory motion, the vertically directed oscillations are transmitted through the post 10, the bracket and the holder 8 to the cup 5, which oscillates around the axis 13 of the hinge 4.

As a result of oscillations of a glass, finely dispersed particles of dirt with a diameter, for example, less than 1 µm, settled on a conical surface.

strength due to adhesion forces and electrical forces, are detached and moved under the action of centrifugal force until the next contact

5 with a surface.

This process is repeated until the particles enter the channel of the capillary tube 7.

The degree of separation of solid finely dispersed particles from the analyzed liquid in the proposed centrifuge with the vibration of glasses increases in comparison with limestone, in which these particles remain on conical surfaces during the entire process of sample processing.
