Title: SUBMERGED-MOTOR-PUMP PROTECTION PUMPING-PIPE FOR DEEP WELL
Abstract:
The present invention relates to a submerged-motor-pump protection pumping-pipe for a deep well that can achieve safe construction of a pumping pipe to be installed in a deep well and stable pumping through a submerged motor pump. To achieve this, the present invention provides a submerged-motor-pump protection pumping-pipe for a deep well, comprising: a guide means for constructing a pumping pipe in a borehole, the pumping pipe including a first pipe to which a submerged motor pump is attached and second to nth pipes connected thereto; a packing that is divided into halves in the longitudinal direction to surround the first pipe and has first fixing parts formed on the upper and lower portion thereof, an extending part formed between the first fixing parts, and a longitudinal cutaway part formed on the surface thereof; a clamp band coupled to the first fixing parts to secure the packing to the pumping pipe; and a first coupling secured to the opposite ends of the packing through insertion into the first pipe, wherein the first coupling is subjected to injection molding such that first and second vertical guides formed on the outer peripheral surface thereof alternate with each other, thereby making an electric wire and a wire rope pass through a space between the first and second guides.
