Abstract
Modular protector apparatus for oil-filled submergible electric motors that drive submergible pumps comprises pluralities of components that are interconnected in different system permutations to form protectors appropriate for different applications. The components include heads, chambers, bases, and interconnecting bodies. The bodies have fluid passages that are adapted to communicate with other components and that are opened and closed selectively to provide desired inter-component flow paths. By virtue of the invention, a wide variety of protector apparatus may be manufactured economically.

A method of manufacturing protector assemblies for use with oil-filled submergible electric motors of the type employed to drive submergible pumps, each protector assembly having at least one protector chamber, each said protector chamber having a body, comprising the steps of:
- providing a plurality of protector chambers adapted to be interconnected physically and hydraulically to form different protector assemblies, said plurality of protector chambers including protector chambers of different types, each said protector chamber including a pressure equalization system, each said type of protector chamber having communication passages for facilitating fluid communication;
- providing a plurality of identical bodies for coupling at least one of said protector chambers to another component, each of said bodies having a plurality of passages, said passages arranged and oriented to operatively communicate with said communication passages of each of said types of protector chambers;
- selectively opening or closing at least one of said passages in at least one of said bodies to cause said passage to provide a selected opened or closed path of fluid communication with said protector chamber when said body is operatively coupled to said protector chamber;
- and
- operatively coupling said at least one body to at least one of said protector chambers to form a protector assembly.
A method of manufacturing oil-filled submergible electric motors of the type employed to drive submergible pumps, comprising the steps of:
- providing plurality of protector components adapted to be interconnected in different permutations to form different types of protector apparatus, the components including a plurality of identical heads, a plurality of identical chambers of a first type, a plurality of identical chambers of a second type, a plurality of identical bodies, and a plurality of identical bases, each head being adapted to connect any chamber to a submergible pump physically and hydraulically, each body being adapted to interconnect any pair of chambers physically and hydraulically, having a plurality of passages adapted to communicate with connected chambers, and having means for opening and closing passages selectively, whereby selected fluid flow paths are provided between chambers, each body also being adapted to connect any chamber to a base physically and hydraulically;
- and
- forming different systems of the components including a system that comprises a head, at least one chamber of the first type, a body, and a base, and a system that comprises a head, at least one chamber of the second type, a body, and a base to form a protector assembly for coupling to an oil-filled submergible electric pump unit.

- providing pluralities of protector components adapted to be interconnected in different permutations to form different types of protector apparatus, the components including a plurality of identical heads, a plurality of identical chambers of a first type, a plurality of identical chambers of a second type, a plurality of identical bodies, and a plurality of identical bases, each head being adapted to connect any chamber to a submergible pump physically and hydraulically, each body being adapted to interconnect any pair of chambers physically and hydraulically, having a plurality of passages adapted to communicate with connected chambers, and having means for opening and closing passages selectively, whereby selected fluid flow paths are provided between chambers, each body also being adapted to connect any chamber to a base physically and hydraulically;
- and
- forming different systems of the components including a system that comprises a head, at least one chamber of the first type, a body, and a base, and a system that comprises a head, at least one chamber of the second type, a body, and base wherein said first type of chamber comprises a labyrinth chamber type, and wherein said second type of chamber comprises an expansible chamber type to form a protector assembly for coupling to an oil-filled submergible electric pump unit.
A method of manufacturing protector assemblies for use with oil-filled submergible electric motors of the type employed to drive submergible pumps, each protector assembly having at least one protector chamber, each said protector chamber having a body, comprising the steps of:
- providing a plurality of protector chambers adapted to be interconnected physically and hydraulically to form different protector assemblies, said plurality of protector chambers including protector chambers of different types, each said protector chamber including a pressure equalization system, each said type of protector chamber having communication passages for facilitating fluid communication;
- providing a plurality of identical bodies for coupling at least one of said protector chambers to another component, each said body having a plurality of passages at least one of said passages adapted to be selectively operable to be in a first, open, state wherein fluid may pass through said passage, or in a second closed, state, wherein fluid flow is precluded through said passage, said passages arranged and oriented whereby at least one of said passages will operatively communicate with said communication passages of each of said types of protector chambers;
- and
- operatively coupling at least one of said bodies to at least one of said protector chambers, with said selectively operable passage in the appropriate of said first and second states to facilitate operation of said protector chamber when said protector chamber is coupled to said body member to form a protector assembly.
