AI Technical Summary
The installation process of existing submersible pump rubber bearings is difficult, which can easily lead to deformation or damage, affecting service life and efficiency.
The design employs a pressure head and a press-in nested structure, with a guide section and inner snap edge design to stably guide and secure the rubber bearing, ensuring its smooth press-in into the pump body assembly cavity and reducing deformation and damage.
This improves the installation efficiency of rubber bearings, reduces deformation and damage, extends the service life of pump heads, and enhances the overall performance and reliability of submersible pumps for wells.

Abstract
Claims
1. A well submersible pump rubber bearing press-fit structure comprising a pump body and a rubber bearing fitted into the pump body, characterized by: The press-fitting structure includes: Indenter; and A press-fit nest for housing the rubber bearing, wherein the press head is inserted into the press-fit nest; the press-fit nest comprises: The first guide section is used to guide the pressure head; The second guide portion is disposed at the end of the first guide portion and is used to guide the rubber bearing when it is secured and when it is pressed into the assembly cavity of the pump body.
2. A rubber bearing press fit structure for a submersible pump for a well according to claim 1, characterized in that: The second guide portion is an inwardly curved inner edge forming a ring, and the included angle between the inner edge and the first guide portion is 130°-150°.
3. A rubber bearing press-fit structure for a submersible pump for a well according to claim 2, characterized in that: The inner diameter of the opening at the inner buckle is equal to the diameter of the assembly cavity of the pump body.
4. A rubber bearing press fit structure for a submersible pump for a well according to claim 1, characterized in that: The pressure head includes: The sliding end slides up and down in conjunction with the first guide portion; The press-in end abuts against the rubber bearing.
5. A rubber bearing press fit structure for a submersible pump for a well according to claim 4, characterized in that: The diameter of the press-in end is smaller than the diameter of the sliding end, and the diameter of the press-in end is equal to or smaller than the inner diameter of the opening of the inner buckle.
6. The press-fit structure for a rubber bearing of a well submersible pump according to claim 4, characterized in that: The sliding end is coaxial with the first guide portion.
7. A rubber bearing press fit structure for a submersible pump for a well according to claim 4, characterized in that: An inner support body is provided below the press-in end, and the inner support body extends into the rubber bearing.
8. A rubber bearing press fit structure for a submersible pump for a well according to claim 7, characterized in that: The inner support body includes a connecting rod and a support body disposed at the bottom of the connecting rod; wherein, when the pressure head presses into the rubber bearing, the support body abuts against the inner wall surface of the rubber bearing.
9. A rubber bearing press fit structure for a submersible pump for a well according to claim 8, characterized in that: The connecting rod forms an annular space between its circumference, the press-in end, and the support body, allowing the rubber bearing to contract inward.
