Abstract

The invention discloses a water-lubricated thrust bearing assembly. The assembly comprises a thrust disc and a stainless steel thrust disc, wherein the thrust disc comprises a hard metal substrate, the annular end surface of the metal substrate at the contact sides of the thrust disc sector-ring shaped friction blocks is covered with a non-metal wear-resisting layer, the stainless steel thrust disc comprises a stainless steel annular substrate and a plurality of sector-ring shaped friction blocks on one side of the annular substrate, a lubrication water channel is formed between the adjacent sector-ring shaped friction blocks, the corresponding number of the stainless steel sector-ring shaped support blocks with the sector-ring shaped friction blocks are arranged on the other side of the annular substrate, a cool water channel is formed between the adjacent sector-ring shaped support blocks, the sector-ring shaped support blocks and the sector-ring shaped friction blocks are arranged in the circumferential direction in the staggered way, the symmetry axis of the sector-ring shaped support block coincides with the projection of the middle line of the lubrication water channel in the annular end surface of the substrate. The water-lubricated thrust bearing assembly has features of great axial bearing capacity, good cooling effect, great wear resisting capacity, high corrosion resistance, low operation resistance, and long service life.

Description

technical field

[0001] The invention relates to a water-lubricated bearing assembly of a submersible pump, in particular to a water-lubricated thrust bearing grinding assembly installed at the lower end of a submersible pump motor. Background technique

[0002] The water-lubricated thrust bearing assembly is an important part of the submersible pump. It is composed of a cast iron or steel thrust plate installed at the lower end of the submersible pump motor shaft and a thrust plate installed at the bottom of the submersible pump motor housing. When working, the thrust plate and The thrust plate is friction fit, and the axial load of the submersible pump rotor is carried by the thrust plate. Since the submersible pumps used in deep wells require a higher lift, the number of stages of the submersible pumps and the power of the motor need to be increased, which makes the water-lubricated thrust bearing assembly need to carry a larger axial load. The thrust plate used in early ...
