MACHINES LUBRICATION SYSTEM
The principle of improvement of machines and mechanisms friction joints lubrication system has been worked out.
Oxygen dissolved in oil in balanced conditions stipulates the running of oxidizing thermo- and tribochemical processes
which influence negatively both the forming tribojoints operation indices and their lubrication systems: decrease in
friction steam wear-resistance, oil ageing. The essence of the principle is in providing of oxidizing phenomena inhibition
in oil surroundings by saturating of the system with neutral gas (nitrogen). As the result of the dissolved in oil products
oxygen diffusion into this gas, their rectification from oxygen takes place.
Carrying out desorption in closed volume with pipe-bend is conducive to deoxidizing not only liquid but air space above
it. To provide lubrication systems with necessary quantity of neutral gas the method of gaining enough quantity of inert
gas directly in the process of operation has been worked out.
Technical characteristics. The system has
the main oil tank, to which the oil pump 2, oil cooler 3, filter 4,
fluid friction bearings 5 are connected in succession. Reservoir
6 for collecting non-conditioned oil has the bulkhead 7, which
5 partitions off hermetic section 8, which is connected by a
30
bypass line with bolt 9. Flowing of dirty oil from: conditioner
1, stand 11, filter 4 along line 12 is connected to reservoir 6.
31 4 The settled oil runs to regenerator along the pipe 13. The
29
12 pulley for receiving of inert gas surroundings is situated in
section 8. Receiver 20 is connected to the upper part of the
32 3
27 28 26 36 section. The cooler 21 (condenser of water steam) is situated
35 inside the receiver 20. Union 22 for draining water is in the
25 34 2
24 1 lower part of the receiver 20 and selector 23, which takes gas
33 samples for chemical analyses, safety-valve 24 and main slide-
23 10
valve 25 are in the upper part of the receiver 20. Gas-pipe 26
21 is connected to the tank with oil 1; gas-pipe 27 – to electric
20 11 thermo satellite 28, which is laid under pipe 29, with the help
22
19 of which the oil is transported from store to the tank 1; gas-
18
pipe 30 is connected to water lacuna of the reserve grease

cooler in the sector the of dead admission water-pipe 31 (after
6 the bolt). Reverse-valve 32 prevents overpressure of inert gas

Sphere of application: lubrication systems of steam turbines, compressors, cotton-spinning machines, rolling-mills,
internal-combustion engines, technological equipment, machine-tools.
Comparison with analog (advantages): The slowing down of the oxidizing processes intensity by decreasing contents of
the dissolved oxygen in oil because of saturating the surroundings by the neutral gas nitrogen is conducive to complex
improvement of friction joints wear-resistance and increasing the time of oil work (without change) because of inhibition
its “ageing”. As the result the oxidizing stability and wear-proof quality of oil increase by 1.3, 1.4 times and negative
influence of filling with water decreases.
