Specific embodiment
Below in conjunction with the accompanying drawings the present invention is described in further detail with specific embodiment.
As shown in figure 1, a kind of high-temperature submersible electric pump plane thrust bearing arrangement, including dynamic plate 1 and quiet plate 2, it is latent in high temperature
Equipped with dynamic plate containment vessel 4, the dynamic plate 1 is embedded in dynamic plate containment vessel 4 fixed cover on oily electric pump hollow spindle 3, and dynamic 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, it has high rigidity, high abrasion
The good characteristic of property, at 500 DEG C, the hardness and wearability of YG20C tungsten-cobalt alloys also will not change technology temperature.Due to
The Toughness Ratio bearing steel of YG20C tungsten-cobalt alloys is a bit weaker, and in order at utmost avoid dynamic plate 1 from crushing, dynamic plate 1 is embedded in
In dynamic plate containment vessel 4.
The material of the dynamic plate containment vessel 4 is the iron-nickel alloy of 4J42.For 4J42 iron-nickel alloys, its have with
The close coefficient of expansion of YG20C tungsten-cobalt alloys, is a kind of fabulous insert material, dynamic plate 1 can be effectively ensured after insert not
Come off and do not crush.
Pairing between the dynamic plate 1 and quiet plate 2 forms friction pair 6, 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 by lappingout, can be made
The roughness grade of dynamic plate 1 and quiet plate 2 brings up to minute surface level, and coefficient of friction can be less, and makes frictional heat lower.
Offer on the corresponding high-temperature submersible electric pump hollow spindle 3 of the friction pair 6 and get rid of oilhole 9, lubricating oil is by getting rid of oil
Get rid of to friction pair 6 in hole 9.Lubricating oil under the action of the centrifugal force, constantly can be thrown away into friction pair 6, so as to effective from getting rid of oilhole 9
Increase the flow of lubrication in friction pair 6, further improve lubrication and radiating effect.
Flat key 7, high-temperature submersible electric pump are provided between the dynamic plate containment vessel 4 and high-temperature submersible electric pump hollow spindle 3
Hollow spindle 3 is by the transmitting torque of flat key 7 to dynamic plate containment vessel 4 and dynamic plate 1.In dynamic plate containment vessel 4 and the rotation process of dynamic plate 1
In, effectively prevent the stress concentration of dynamic plate 1.
Pad 8 is added between the quiet plate 2 and high-temperature submersible electric pump housing 5, pad 8 adopts soft metal.Pad 8
By taking red copper pad as an example, can effectively mitigate and alleviate the rigid impact that quiet plate 2 is subject to by red copper pad.
The dynamic top of plate containment vessel 4 be oil storage space 10, the hollow master of the high-temperature submersible electric pump in oil storage space 10
