The invention discloses a rotating variable capacity pump with axisymmetric curved surfaces, and relates to the field of variable capacity pump manufacturing. The variable capacity pump comprises a pump body, a main shaft, a separating plate, rotating pieces, a pump liquid outlet and a pump suction inlet, wherein the main shaft is arranged inside the pump body; the separating plate is arranged at the middle part of the main shaft; the rotating pieces are arranged at two ends of the separating plate; the pump liquid outlet and the pump suction inlet are formed in two sides of the pump body; the pump liquid outlet is connected with a segment of a vertically upward conveying pipeline. The variable capacity pump can prevent the opposite surfaces of the rotating pieces and the separating plate from being scoured and worn by high-pressure fluid, and is long in service lives of the rotating pieces, high in pump efficiency and is adaptable to three-phase mixed conveying of gas, water and oil.
Description
technical field [0001] The invention is an improvement to the axisymmetric curved surface rotary variable capacity pump, especially relates to a pump that can prevent the facing surfaces of the rotary vane and the partition plate from being scoured and worn by high-pressure fluid, the service life of the rotary vane is long, the pump efficiency is high, and it can pump air and water. , Oil three-phase mixed transmission axisymmetric curved surface rotary variable displacement pump. Background technique [0002] Axisymmetric curved surface rotary variable displacement pump is a new type of rotary volumetric pump, its working efficiency is very high, the pumping efficiency is as high as 70-80%, which is about 30-40% higher than that of ordinary centrifugal pumps, especially in small flow, When used under high pressure conditions, the efficiency will be about 40% higher than that of centrifugal pumps. For example, the flow rate is 20~30m 3 / h, a centrifugal pump with a head o...
