Description
Technical field
This utility model belongs to air separation turbocompressor field, is specifically related to a kind of turbine sliding bearing.
Background technology
It is exactly low temperature processing that air separates industrially most common method, and air supplies after all needing turbocompressor pressurization
Rear system uses, and turbocompressor is generally individually equipped with a set of independent lubricating oil station system, and general lubricating oil is through oil pump, cooled
After device cooling, enter twin filter, after pressure regulation, after filtering out impurity, flow to each sliding bearing needing lubrication, tooth respectively
Wheel.Lubricating oil forms oil film, support shaft and rotor thereof in sliding bearing and runs well, and takes away the heat of generation.
Owing to lubricating oil can produce degraded when compressor runs up, and temperature is the highest more easily degrades, and easily produces
Paint film.
Paint film is a kind of higher hydrocabon base polymer, and typical elementary analysis is as follows: C, 81%～85%, H, 7%～
9%, O, 7%～9%, N, 2%～3%, color from light brown, brown to sepia.Paint film is using the machinery of a period of time
Equipment fluid generally exists, especially the most common in steam turbine oil and the higher hydraulic system oil liquid of pressure.Paint film has pole
Property, easily stick to metal surface.The harm of paint film has: reduces gap, increase friction, causes spool bond operation to be lost time serious
Spirit；Blocking filter causes equipment lubrication bad；On cooler the paint film of deposition cause dispelling the heat bad, oil temperature rises, oil product oxygen
Change and accelerate；Paint film can adhere to solid particle, causes equipment abrasive wear.
Paint film is oil deterioration product, and formation mechenism is broadly divided into oil oxidation and fluid " micro-combustion " two class, this reality
It is primarily upon oil oxidation with novel.
Hydro carbons oil oxidation follows radical chain reaction mechanism, generates the peroxide such as carboxylic acid, ester, alcohol after oxidation.These
The further polycondensation reaction of peroxide generates the polymer of high molecular, such as paint film and greasy filth.Being distinguished as of paint film and greasy filth:
(1) temperature that paint film generates is higher, and low temperature is more beneficial for the generation of greasy filth；(2) containing a certain amount of moisture in greasy filth.
Fluid contacts and is in certain temperature conditions with air and metal material the most always.Research table
Bright, temperature, water, air and metallic catalyst are to accelerate the basic reason that oil ageing is rotten, and the rule of impact has: (1) oil
Liquid temp often improves 10 DEG C, and oxidation rate increases by 1 times；(2) exceeding a certain amount of moisture can make oil oxidation speed increase by 10
On times one；(3) along with the increase of air content in fluid, the paint film that oxidation generates is the most linearly increasing；(4) metal in fluid
Grain can accelerate oil oxidation as catalyst.
Along with paint film formation on bearing tile, the vibration of turbocompressor and temperature signal can produce irregular ripple
Dynamic, constantly it is attached on tile fragment mainly due to paint film, changes the structure of tile fragment, have impact on the heat exchange effect of tile fragment and lubricating oil
Really, further resulting in a watt temperature and slowly rise, and the rising of temperature is the formation that can encourage paint film, thus formation one is pernicious
Circulation.
At present to controlling and reduce paint film method to have external oil filtration system, employing resin filter element is mainly had to pass through outer circulation
Method constantly the paint film precursor of the dissolved is removed from running oil；The method thoroughly eradicating paint film has employing high-performance axle
Hold, the lubricating oil simultaneously more renewed.Both controls the method for paint film and is required for bigger investment, particularly high-performance bearing
Price is 10 times of general bearing.
Summary of the invention
The purpose of this utility model is to provide a kind of turbine sliding bearing, is improved by structure, increases lubricating oil
Flow, improves the heat exchange situation at tile fragment, reduces watt temperature about 10 DEG C, thus reaches to delay the purpose of varnish formation.
For reaching above-mentioned purpose, the technical solution of the utility model is:
A kind of turbine sliding bearing, it is split-type structure, is made up of two split bodies, and each split body includes, axle
Bearing, for semi-circular ring, circumferentially sets annular groove in the middle part of bearing block extrados, to should annular groove, it offers two
The most through oilhole；Bearing block intrados offers in the middle part of an annular anchoring groove, and this intrados two the most respectively
Side respectively sets a fixing hole；Upper and lower catch, in semicircular ring structure, the end face of upper stop piece and the outer side bottom surface end of lower stop piece are circumferentially
If step surface, and it is embedded at, with this this outboard end, the annular anchoring groove that described bearing block intrados is upper and lower；The bottom surface of upper stop piece
And in the middle part of the end face of lower stop piece, circumferentially setting annular guide channel, bottom upper stop piece intrados and lower stop piece intrados top is the most convex
If a collar stop；Habenaria dipionema Sohltr block, tile fragment is curved, and tile fragment upper and lower end face sets guide pillar, and is arranged at described upper stop piece with this
Annular guide channel in the middle part of the end face of bottom surface and lower stop piece；Set fixing post in the middle part of tile fragment extrados, be arranged at described bearing block with this
Fixing hole in the middle part of intrados；Tile fragment intrados one side end is inclined-plane.
Further, the diameter of the fixing hole in the middle part of described bearing block intrados is more than fixing in the middle part of described tile fragment extrados
Column diameter 0.1～0.5mm.
This utility model is that the sliding bearing extending and easily generating paint film oil system uses the time, by sliding bearing tile fragment
Do a certain amount of biasing (cut away a part for tile fragment intrados one side end, this side end formed inclined-plane), increase tile fragment
Oil catch (collar stop) internal diameter etc., makes the temperature at tile fragment reduce by 10～15 DEG C, thus reaches the speed delaying paint film to generate,
Extend the service life of sliding bearing.
The beneficial effects of the utility model:
1, delay the sliding bearing paint film problem that lubricating oil degradation brings, prevent paint film (half a year) in a short time from being formed.
2, improve the service life of the sliding bearing of large-scale compressor group, increase economic efficiency.
3, the reliability and stability of unit operation are improved.
