Abstract
Description
technical field
[0001] The invention relates to a power vane pump or motor that directly exchanges power with fluid energy, especially can increase the output pressure, flow rate, efficiency of the power pump or the rationality and efficiency of the motor absorbing fluid power, and the extended application of the method. Background technique
[0002] At present, the dynamic vane pump has stable fluid output, basically no pulsation, and the rolling fit between the pump vane and the pump body is non-contact friction. It is widely used, but its output pressure or flow as a pump is small. The power exchange efficiency is low, which reduces its application volume and scope, so it is an important issue to increase the output pressure and efficiency of the pump, and to improve the exchange efficiency of the fluid and power of the power vane pump as a motor.

Embodiment Construction
[0015] exist figure 1 Among them, the fins (7, 9, 11, 16, 17) of the pump supercharger are subjected to the rotational movement of the pump blades (10, 12, 14) so that the fluid is sheared and extruded to flow to the fins of the supercharger One side, (2) is the action fluid surface of the sharp angle between the supercharger fin and the pump blade, and the mating surface of the pump blade (in the application of axial flow pump) or the tangent line of the sharp angle (in the application of centrifugal pump) (18) The included angle is R 2 , the smaller the angle is, the better it is for the supercharger fin to shear the fluid, and the more the conversion efficiency between the power of the pump blade and the fluid flow is increased; (8) is the matching surface of the supercharger fin and the sharp angle of the pump blade at the shortest distance, ( The sharp angle formed by 2 and 8) is the closest part between the turbocharger fin and the pump blade, (8) and the pump blade m...
