Problems solved by technology

Gears with these tooth profile curves have their own advantages in transmission, but they will generate high output pulsation during transmission, which will affect the stability of transmission and shorten the service life of the pump.
Moreover, the processing of the above tooth profile curves is difficult and costly

Abstract

The invention discloses a transfer pump of a high viscosity fluid. The transfer pump which comprises an end cover (1), an internal gear (2), a fixed shaft (4), a pump body (5), an external gear (7), a right end cover (8), a support (12), and a transmission shaft (15) is characterized in that: an inner geared gear pair which is composed of the internal gear (2) and the external gear (7) is arranged in the pump body (5); the external gear (7) is a driving gear, the internal gear (2) is a driven gear; tooth profile curves of the gears are arc in shape, and the centers of the internal arc and the external arc of a crescent shaped plate are respectively coincident with centers of the internal gear (2) and the external gear (7). The transfer pump of the present invention has the advantages of strong self-priming capability, realization of high viscosity fluid transfer, stable transfer, long life, low cost and the like.

Description

technical field [0001] The invention relates to the field of fluid machinery, in particular to a high-viscosity fluid transmission pump. Background technique [0002] The gear pair in the internal gear pump and the crescent member between the gear pair have a great influence on the working performance of the pump. [0003] The traditional internal gear pump uses the internal gear as the driving wheel, the external gear as the driven wheel, and the design of the offset crescent plate. This design is suitable for the transmission of fluids with a certain viscosity such as organic acids, animal fats, and vegetable oils. Due to the weak self-priming ability of the traditional internal gear pump for high-viscosity fluid, there will be problems such as low transmission efficiency during transmission, or even failure to work normally. [0004] The gears used in traditional internal gear pumps mostly use cycloids, straight lines and compound curves for their tooth profile curves. ...
