FIELD: well drilling technology. ^ SUBSTANCE: device has combined, consisting of at least two parts metallic body with channel for flow of liquid, nipple ends of body with connecting threads on them, electro-insulating material respectively on the body, on channel surface and between body parts in their engagement(mating). Nipple ends of both parts of body are made with tails coaxial to the latter, in each of which on the end side a recess is made for placement of electro-conductors. Further portions of channels for electro-conductors are made in body parts in form of longitudinal groove along channel generating line for liquid flow. ^ EFFECT: higher durability and reliability of separator, as well as an additional functional capability for it. ^ 1 dwg |
