Winding and unwinding stator of spindle drag pump - comprises reel and flexible tape wound spirally around stator from one end to other

摘要

The device is used to wind and unwind the stator (1) of a spindle drag pump. The stator (1) has a cylindrical outer form with a suction end and a pressure end, and the rotor (3) rotates and oscillates radially within the stator (1). - The device comprises a reel (5) around which a draw tape winds and unwinds. The reel (5) has a mounting (6). The tape (4) is wound spirally around the stator (1) from one end to the other, and the rotor (3) has a device (7) to prevent it rotating.
