摘要： A submersible electric motor has feature to enhance thermal conductivity from the motor interior to the exterior. The motor has a cylindrical housing and a stator rigidly mounted within housing. A rotatable rotor is located within the stator. A gap formed between the stator's outer diameter and the inner wall of the housing is filled with a high thermal conductivity material to improve heat transfer from the motor. The remaining portion of the housing may be filled with a dielectric lubricant that has lesser thermal conductivity than the high thermal conductivity material.

摘要： A heat-pipe electric-power generating device capable of converting thermal energy to electrical energy is provided. The device includes a heat pipe and the heat pipe has a sealed internal space that can produce a steam-flow from an evaporating end to a condensing end according to a pressure difference caused by a temperature difference between the ends. A steam-flow electric-power generating device has at least a rotating portion disposed in the internal space for generating electric power when driven by a steam-flow. An electrode structure is used for leading the electric power out. The heat pipe is maintained in a sealed condition. In addition, several heat-pipe electric-power generating devices can be arranged into an array to form a heat electric-power generator or disposed inside an apparatus with a heat source for recycling the conventional waste thermal energy into useful electrical energy.

摘要： The invention relates to crude oil production, and can be suitably used for hydroprotection of submersible electric centrifugal motors. A hydroprotection protector of a borehole pump electric motor comprises at least one stage, which stage includes a cylindrical body (7), a tube (8) coaxially positioned inside said body and surrounding a shaft (5), nipples (9, 10), a damping bushing (11), an end-face seal (12) and an annular piston (13), which piston is adapted to reciprocate in an annular chamber (14), which chamber is defined within the space between the cylindrical body (7) and the tube (8). The piston (13) separates the chamber (14) into two areas (15, 16) filled, respectively, with the dielectric fluid and the formation fluid arriving from the annulus. Two protective annular elements (17, 18) are attached to the piston (13) end-face, contacting the formation fluid, the protective annular elements (17, 18) protrude beyond outline of the piston and are contiguous, respectively, to the body (7) interior surface and to the tube (8) exterior surface. The space between the elements (17, 18) and the surfaces of body (7) and tube (8), contiguous to said elements, is filled with a protective lubricant. Embodiment of the invention prevents the formation fluid from seeping into the chamber containing the dielectric fluid, and allows to avoid contamination and wear of chamber's surfaces subjected to friction.
