Embodiment Construction

[0019] The present invention will be further described below in conjunction with accompanying drawing.

[0020] Such as figure 1 , figure 2 As shown, the vane differential pump driven by an incomplete gear mechanism in the present invention is mainly composed of an incomplete gear mechanism driving system 1 and a pump body 7 .

[0021] The incomplete gear mechanism drive system 1 is mainly composed of a drive shaft 2, a first output shaft 14, a second output shaft 15, a first incomplete gear 3, a second incomplete gear 4, and a third incomplete gear mounted on the drive shaft 2. Gear 5 and the fourth incomplete gear 6, the first spur gear 13, the second spur gear 12 installed on the first output shaft 14, the third spur gear 11 and the fourth spur gear installed on the second output shaft 15 10 composition; at the initial position, the first incomplete gear 3 meshes with the first spur gear 13, the second incomplete gear 4 separates from the second spur gear 12, and the thi...

Abstract

The invention discloses an incomplete gear mechanism-driven blade differential pump. The pump comprises an incomplete gear mechanism driving system and a pump body; the incomplete gear mechanism driving system consists of four pairs of incomplete gear mechanisms, a driving shaft and two output shafts, wherein the driving shaft is fixedly connected with a three-phase asynchronous motor, the two output shafts are fixedly connected with two impeller shafts respectively, two blades are arranged on each impeller shaft, and the adjoining blades and a pump housing form a seal cavity. Aiming at the defect that the existing volume pump is small in displacement, unbalanced in radial force and the like, the incomplete gear mechanism driving system and the impellers coaxially installed within the pump housing are combined with one another, and the incomplete gears are periodically meshed with and separated from one another, so that the uniform rotation is converted into the periodic non-uniform velocity rotation, and the blades on the two impellers are periodically opened and closed, therefore, the volume of the seal cavity formed by the adjoining blades and the pump housing is periodically changed, the liquid discharging process and the liquid absorbing process of the pump can be realized, and the applicability of the volume pump in the fields of industrial production and life can be improved.

Description

technical field [0001] The invention relates to a displacement pump, in particular to a periodic differential rotation of the impeller shaft by driving an incomplete gear mechanism, and then drives the blades to open and close periodically, so as to realize the change of the volume of the closed cavity and complete the differential speed of the blades. Vane differential pump driven by incomplete gear mechanism for pump suction and discharge process. Background technique [0002] The vane differential pump is a new type of volumetric pump, which relies on the periodic changes in the volume of the closed working space contained in the liquid to periodically transfer energy to the liquid. The current positive displacement pump has defects such as unbalanced radial load on the rotor and small displacement volume ratio, which makes it difficult for the positive displacement pump to be widely used. In order to expand the application field of the displacement pump, the present inv...
