Specific embodiment
The present invention is described in further detail in the following with reference to the drawings and specific embodiments.
As shown in Figure 1, a kind of high-temperature submersible electric pump plane thrust bearing arrangement, including movable plate 1 and quiet plate 2, dives in high temperature
Fixing sleeve is equipped with movable plate protective shell 4 on oily electric pump hollow spindle 3, and the movable plate 1 is embedded in movable plate protective shell 4, and movable plate 1 with
It is contactless between high-temperature submersible electric pump hollow spindle 3；The quiet plate 2 is fixedly mounted on high-temperature submersible electric pump housing 5；It is described dynamic
The material of plate 1 and quiet plate 2 is the tungsten-cobalt alloy of YG20C.For YG20C tungsten-cobalt alloys, with high rigidity, high abrasion
The good characteristic of property, at 500 DEG C, the hardness and wearability of YG20C tungsten-cobalt alloys will not change technology temperature.Due to
The toughness of YG20C tungsten-cobalt alloys is more a bit weaker than bearing steel, and in order to utmostly avoid movable plate 1 broken, movable plate 1 is embedded in
In movable plate protective shell 4.
The material of the movable plate protective shell 4 is the iron-nickel alloy of 4J42.For 4J42 iron-nickel alloys, have with
The coefficient of expansion similar in YG20C tungsten-cobalt alloys is a kind of fabulous insert material, movable plate 1 can be effectively ensured after insert not
It comes off and does not crush.
Pairing forms friction pair 6 between the movable plate 1 and quiet plate 2, is lubricated at friction pair 6, and the quiet of friction pair 6 rubs
It is 0.05 to wipe coefficient, and the coefficient of kinetic friction of friction pair 6 is 0.029~0.12.In the fabrication process, polished, can made by lappingout
The roughness grade of movable plate 1 and quiet plate 2 is increased to minute surface grade, and coefficient of friction can be with smaller, and makes frictional heat lower.
It is offered on the secondary 6 corresponding high-temperature submersible electric pump hollow spindles 3 of friction and gets rid of oilhole 9, lubricating oil is by getting rid of oil
It gets rid of to friction pair 6 in hole 9.Lubricating oil under the action of the centrifugal force, can constantly from get rid of oilhole 9 throw away to friction pair 6 in, so as to effectively
Increase the flow of lubrication in friction pair 6, further improve lubrication and heat dissipation effect.
Flat key 7, high-temperature submersible electric pump are provided between the movable plate protective shell 4 and high-temperature submersible electric pump hollow spindle 3
Hollow spindle 3 transfers torque to movable plate protective shell 4 and movable plate 1 by flat key 7.In 1 rotation process of movable plate protective shell 4 and movable plate
In, effectively prevent the stress concentration of movable plate 1.
Gasket 8 is added between the quiet plate 2 and high-temperature submersible electric pump housing 5, gasket 8 uses soft metal.Gasket 8
By taking red copper gasket as an example, effectively it can mitigate and alleviate the hardness that quiet plate 2 is subject to by red copper gasket and impact.
4 top of movable plate protective shell be oil storage space 10, the hollow master of high-temperature submersible electric pump in oil storage space 10
Main shaft pillar 11 is set on axis 3, high-temperature submersible electric pump hollow spindle 3 passes through the lubrication in main shaft pillar 11 and oil storage space 10
Oil phase is isolated.By the lubricating oil of convection circulation in oil storage space 10, heat dissipation effect can be made more preferable, while pass through main shaft pillar
11 keep apart high-temperature submersible electric pump hollow spindle 3 and the lubricating oil in oil storage space 10, avoid most lubricating oil high
Warm submersible electric pump hollow spindle 3 drives rotation, effectively eliminates agitation heat.
Illustrate the one-off process of the present invention below in conjunction with the accompanying drawings：
First, high-temperature submersible electric pump hollow spindle 3, which rotates, drives movable plate protective shell 4 to rotate, and then movable plate 1 is driven to turn together
It is dynamic, sticky and quiet 2 surface grooves of plate of lubricating oil is subject to act on, shape in friction pair 6 that can be between movable plate 1 and quiet plate 2
Into the oil film with certain bearing capacity, and when rotating speed is higher and the viscosity of lubricating oil is bigger, then the thickness of oil film is also just also big, this
When greasy property it is better.Meanwhile the lubricating oil in high-temperature submersible electric pump hollow spindle 3 is under the action of the centrifugal force, can constantly from
It gets rid of oilhole 9 to throw away into friction pair 6, so as to the flow of lubrication being effectively increased in friction pair 6, further improves lubrication and heat dissipation
Effect.
When under static state, the lubricating oil in friction pair 6 can be forced out under the effect of gravity, the table of movable plate 1 and quiet plate 2
It is separated between face by oxide layer and adsorption layer, therefore, starts moment, the startup between movable plate 1 and quiet plate 2 in high-temperature submersible electric pump
Frictional force is in maximum, and this Frotteurism is referred to as boundary friction.
When the rotating speed of movable plate 1 reaches normal speed, due to the viscous effect of adsorption layer and lubricating oil, lubricating oil can be passive
Plate 1 drives and in engaging friction pair 6, and then the oil film thickness in friction pair 6 can increase, and make between movable plate 1 and quiet plate 2 by half-dried
Boundary friction is changed into liquid friction, and the pressure in oil film can also raise, and realizes the favourable operating condition under liquid friction.
Scheme in embodiment be not to limit the scope of patent protection of the present invention, it is all without departing from carried out by the present invention etc.
Effect implements or change, is both contained in the scope of the claims of this case.
