Shim Free Pothead Housing Connection to Motor of Electrical Submersible Well Pump

摘要

A submersible well pump assembly has an electrical motor connected with the pump. An electrical receptacle on the motor has a base into which a central bore and first and second threaded holes on opposite sides of the bore extend, the threaded holes having nominal major diameters that are the same. A motor lead extends to the motor and has an electrical connector that mates with the receptacle. The electrical connector has a flange containing first and second bolt holes, the second bolt hole having a diameter nearly the same as the diameter of the second threaded hole. The first bolt hole has a diameter that is larger than the diameter of the second bolt hole and also larger than the diameter of the first threaded hole. Bolts extend through the bolt holes into threaded engagement with the threaded holes.

主权项

1. A submersible well pump assembly, comprising:
a pump; an electrical motor operatively connected with the pump for driving the pump; an electrical receptacle on the motor that has a base into which a central bore and first and second threaded holes on opposite sides of the bore extend; a motor lead extending to the motor and having an electrical connector on an end of the motor lead that mates with the receptacles, the electrical connector having a plurality of electrical conductors, each having a motor lead terminal for electrically connecting with a mating motor terminal in the motor; the electrical connector having a flange containing first and second bolt holes, the first bolt hole having a larger cross sectional area than a cross sectional area of the second bolt hole and also larger than the cross sectional, area of the first threaded hole; and a pair of bolts, one extending through the first bolt hole into the first threaded hole and the other extending through the second bolt hole into the second threaded hole to secure the electrical connector to the electrical receptacle.
