The invention discloses a long-life spiral energy exchange device, wherein, a stator of the long-life spiral energy exchange device comprises an outer cylinder and an elastic stator rubber core which is made of flexible elastic materials; the outerwall of the stator rubber core has a cylindrical shape which is matched with the shape of a cavity body of the outer cylinder, and the inner wall of the stator rubber core has a double-head or multi-head spiral cavity which is matched with a rotor; the stator rubber core is fixed inside a cavity of the outer cylinder in the axial direction and the circumferential direction; an annular hollow inner tube which is also made of flexible elastic materials is arranged inside an annular space between the stator rubber core and the outer cylinder and sleeved on the outerwall of the stator rubber core; a slurry inlet/outlet is arranged on the inner tube; an inner tube joint is arranged on the slurry inlet/outlet; a slurry inlet/outlet is also arranged on the side wall of the stator rubber core; and a joint is arranged on the slurry inlet/outlet and connected with the inner tube joint through a duct. The spiral energy exchange device can make up for the abrasion of the stator and the enlarged gap caused by shrinkage of the stator rubber core when the pressure is increased through expansion of the inner tube, and maintains high volumetric efficiency for a long time.
