AI Technical Summary
Technical Problem
Existing electrical submersible pumps (ESP) face difficulties in removing and replacing the pressure equalizing bladder due to adhesive bonding, which requires discarding part of the expensive retainer during maintenance, making the process inefficient and costly.
Method used
The use of rigid sleeves bonded to the bladder ends and secured by retaining rings or set screws, allowing easy detachment and reusability of the retainers, thereby simplifying maintenance and reducing waste.
Benefits of technology
Facilitates easy disassembly and replacement of the bladder without damaging the retainers, reducing maintenance costs and extending the lifespan of ESP components.

Abstract
A well pump seal section housing (25) connects between a pump (13) and a motor (17). Upper and lower retainers (37, 59) at upper and lower ends of the housing have outward facing cylindrical walls (41, 61). Bladder (45) has an interior in fluid communication with dielectric lubricant in the motor. Rigid upper and lower sleeves (51, 69) are bonded within upper and lower openings of the bladder. The sleeves slide over the cylindrical walls of the retainers and are sealed by seal rings (43, 63).Fasteners (57, 77) secure the sleeves to the cylindrical walls.
