Neck Clamp for Electrical Submersible Pump and Method of Installation

摘要

A well pump assembly has a number modules, including a pump and a motor, secured together. Each of the modules has a housing, and at least one of the modules has a neck of reduced diameter relative to the housing. A clamp is secured around the neck. The clamp has a dovetail groove extending around and within the outer surface of the clamp. An accessary member protrudes radially outward from the outer surface of the clamp and has an inner portion located in the groove. A threaded fastener secures the accessary member to the clamp. The accessary member is slidable along the groove to a selected orientation prior to tightening the fastener.
