Description

The invention relates to installations for controlling the purity of working media and can be used in the manufacture and testing of hydraulic, fuel, and oil systems.

The aim of the invention is to improve the accuracy and performance of the control and to expand the technological and operational capabilities of the installation.

The drawing shows a schematic diagram of the installation.

The installation contains a cylindrical body 1 having a calibrated volume, with a piston 2 located therein with a mechanism 3 for its movement, an interchangeable coarse filter 4 and an optically transparent glass 5. The drain pipe 6 is connected to the output pipe by means of a three-way valve 7 the pipeline 9 and the node 10 control filtering, equipped with a rotary cassette 11, having a control and working position and a replaceable filter 12 fine cleaning. The test position of the filter 12 is protected by optically transparent glass 13.

Above the housing 1 perpendicular to the plane of the optical transparent glasses 5 and 13 on the scanning device 14 an optical system 15c is installed with the possibility of relative movement parallel to the plane of the glasses 5 and 13. The optical system 15 is connected via an information pick-up device 16 (for example, a television camera with a video monitor ) and an information processing device 17 (for example, an automatic particle control device) with an information recording device 18.

The inlet pipe 9 through a three-way valve 19 is connected to an additional outlet pipe 20 located under the bottom of the piston 2 in its extreme upper position and having a gas supply system 21 into the cavity of the housing 1. To the working medium line 22, the output pipe 9 is connected through an air separator 23, a flow meter 24 and check valve 25.

The inlet pipes 26 and 27 are connected to line 22 by a crane 28. On pipe 27, a fine filter 29 and a check valve 30 are installed. On line 22, an installation mode regulator 31 is installed. To protect the installation from the ingress of extraneous inclusions, the installation has a casing 32 of optically transparent material.

The device works as follows.

When sampling, the mode control 31 is set to the Selection position and the working medium from line 22 through valve 28 through line 26 enters the cylindrical body 1 with a tared volume and out through valve 19 through line 9 into line 22. When carrying out control of the control medium the operating mode torus 31 is set to the trunk position.

In the case of separate (large and small fractions) control, the housing 1 is disconnected from the main line by a crane 28. The piston 2 moves from the position 2i to the extreme upper position 22 by means of the movement mechanism 3, and the replaceable filter 4 with settled mechanical impurities with particles of a large fraction is pressed tightly against the optically transparent glass 5. Particles of the fine fraction together with the controlled working medium enter from the upper part of the housing 1 through a replaceable filter 4 to the lower part of the housing 1,

The optical system 15, the information retrieval device 16 and the program-controlled scanning device 14 are switched on, moving the optical device 15 installed on it to view the entire area of the filter 4 according to a given program both continuously and discretely. The parameters and the number of soil particles are analyzed automatically by means of device 17. If the size and number of particles of a large fraction are normal, then the control over particles of a large fraction will end.

When controlling particles of the fine fraction, the piston 2 remains in the extreme upper position 22. A replaceable fine filter 12 is installed in the control filtration unit 10 at position C and D of the rotary cassette 11, the valve 7 is opened and the working medium located in the housing 1 is piped 6 and 9, displaced by purified neutral gas from device 21, passes through filter 12 (pos. B) and is directed to line 22. Fine filter 12 with unfiltered controlled particles on it using a turning cassette 11 from working position B At the control position G under the optically transparent glass 13. The optical device 16 with the help of the scanning system moves from the control position A to the control position B.

Filter 12 at position D is viewed similarly to the control of large particles on filter 4. After analyzing the particles on filter element 12 (pos. D), the used filter element is removed. The newly installed fine filter 12 is moved to the filtration position B.

When inspecting the unsplitted (into large and small fractions) calibrated volume of the working medium, the piston 2 is in the extreme upper position 22. The working medium from line 22 is pumped through housing 1 with the help of taps 28 and 19 and pipelines 26, 20 and 9 and is directed to the line 22. Case 1 is disconnected from line 22 by means of a crane 28. The valve 7 is opened and the liquid under the pressure of neutral gas from device 21 through line 6 is expelled from case 1 through filter 12 (in position B) and sent through pipe 9 to highway 22 .

With separate control, the volume of the sample, other than the calibrated volume of the housing 1, the working medium is supplied from the pipe 26 with the valve 19 closed and the piston 2 lowered to the 2i position and open valves -28.7 through the fine filter 12, the air separator 23, the flow meter 24 and a check valve 25 to line 22. After passing through the flow meter 24 a predetermined amount of controlled working medium, the piston 2 is set to the upper position 22 and the large and small particles are counted as if the particles of a tared volume were separately controlled.

With an integral control (for coarse and small fractions) of a sample volume different from the calibrated volume of body 1, piston 2 is in the extreme upper position 2z and the entire flow of controlled working medium from pipe 26 is passed through body 1, drain pipe 6, taps 28 and 7 , the filter element 12 is fine, the air separator 23, the flow meter 24, the check valve 25 and goes to the trunk 22. With the passage of a predetermined volume of working medium through the flow meter 24, the housing 1 is disconnected from the highway 22 by a crane 28. Particles of all sizes, axis Chiyah in Hepa filter 12 are controlled in position 1 in this manner.

When controlling only particles of a large fraction of a sample other than the calibrated volume of body 1, the working medium passes from line 22 through conduit 26 and body 1 with piston 2 installed in position 21 (with valve 19 closed)

through the discharge pipe 6 through valve 7, bypass pipe 8, air separator 23, flow meter 24, check valve 25 into line 22. After passing through the flow meter 24 of a predetermined volume of controlled working medium, piston 2 is set to position 22 and in this way (as with separate control coarse fraction is controlled by the amount and size of the particles.

Protective casing 32 made of transparent material prevents contact with optically transparent glass 5 and 13 foreign particles from the environment.
