Abstract
The invention relates to a positive displacement spherical rotor pump. A pump body and a pump cover are matched to form an inner cavity of a spherical structure. A rotor is arranged in the inner cavity, is of a cardan joint structure and is in a spherical shape on the whole. The rotor comprises two semispherical blocks which are movably connected through a cross piece coupler. A rotor spindle is arranged in the cross piece coupler. The two semispherical blocks and the cross piece coupler form two independent cavities. One side of one semispherical block and one side of the other semispherical block are provided with a driving shaft and a driven shaft respectively. A certain included angle alpha is formed between the driven shaft and the driving shaft in the horizontal direction. The cavities are continuously opened and closed for four times in every cycle of operation of the driving shaft for conveying liquid materials. An overflow valve communicated with the inner cavity is arranged on the top of the pump body. The angle of the driven shaft can be adjusted in the perpendicular direction. The included angle of 10-30 degrees is formed between the driven shaft and the driving shaft in the horizontal direction in the same plane, and therefore the working efficiency of the pump body is adjusted. The positive displacement spherical rotor pump has the advantages of being free of friction, low in noise and low in abrasion, and the service life is prolonged.
