ASSEMBLY TO ATTACH PROTECTOLISER TO PUMP UNIT (VERSIONS) AND UNIVERSAL LAY-ON PROTECTOLISER (VERSIONS) TO FIX EXTENSION CABLE OF PUMPING UNITS

摘要

FIELD: engines and pumps. ^ SUBSTANCE: set of invention may be used in oil industry for protection and attachment of extension cable to electrically-driven rotary pump sections. Protectoliser housing is provided with chamfered flanges with lateral and bottom surfaces jointed along curved line to allow mounting protectoliser on bases of various-size pump sections, and electrically-and-thermally insulated plate to protect said cable against breakdown at the point it is secured by clip. ^ EFFECT: simplified design, reduced overall dimensions, higher reliability and expanded applications. ^ 8 cl, 18 dwg
