The invention provides a torsion spring vane pump for oil well lifting. The torsion spring vane pump for oil well lifting comprises: a cylindrical stator, a rotor disposed inside the stator and vanes arranged on the outer edge of the rotor. The torsion spring vane pump for oil well lifting also includes torque springs disposed in the rotor. The outer ends of the vanes are close to the inner surface of the stator. The inner ends of the vanes abut against the torsion spring. The invention can overcome the problems of difficult throwing of vanes in viscous crude oil and sand jamming in existing double-acting vane pumps. With the advantages of convenient processing and installation, etc., the torsion spring vane pump provided in the invention has a long service life, eliminates the hidden danger that the vane pump vanes cannot be thrown out, and improves the lifting efficiency. The invention is of important significance to crude oil lifting, especially high viscosity well lifting.
