Abstract:
1. An installation assembly for a submersible pump fluid flow sleeve, including a flow sleeve made of a pipe section, the pipe section with a top end opening and a bottom end opening and the pipe section with a length and inside diameter sized for compatibility with a submersible pump, the pump with a top arranged with a discharge and electrical and safety rope connections, a pump suction centrally located, and a bottom arranged with a motor, comprising: (a) a bottom cap, a first upper cap half and a second upper cap half; (b) the bottom cap arranged with two or more flow openings each configured with a flow guide and further arranged with an upper surface and one or more protrusions from the upper surface, the protrusions with an insert surface arranged to provide pipe section support and a well pump centering surface arranged to provide radial pump motor support, the upper surface further arranged with an end cover surface section projecting radially outward from the protrusions and arranged to provide a mating surface with the pipe section bottom end, the upper surface further arranged with one or more well pump support surfaces projecting radially inward of the protrusions and arranged to provide axial pump restraint, (c) the first and second upper cap halves each with a mating surface and at least two alignment protrusion/opening combinations arranged to align the two halves mating surfaces; (d) the aligned first and second upper cap halves providing an insert surface arranged to insert into and mate with the pipe section inside diameter and an end cover surface arranged to mate with the pipe section top end; (e) the aligned halves also providing a discharge opening arranged to fit around the submersible pump discharge, and at least one wiring/safety rope breakaway opening adjacent to the discharge opening arranged to fit around an electrical wire and a safety rope connected to the submersible pump electrical and safety rope connections; and (f) a multiplicity of removable fasteners installed to retain the upper cap halves and bottom cap whereby the bottom cap is installed on the pipe section bottom opening, the pump is installed into the pipe section top opening and supported radially and axially by the bottom cap protrusion well pump centering surfaces and the well pump support surface respectively, and the upper cap halves are aligned around the submersible pump discharge and electrical wire and safety rope and inserted into the pipe section top opening, providing the pump a cooling fluid flowpath through the bottom cap flow openings around the motor to the pump suction.
