Problems solved by technology
In chemical, food, pharmaceutical, bioengineering and other fields, there are high requirements for flow pulsation and flow accuracy, but traditional pumps cannot fully meet the requirements, and product quality cannot be guaranteed during use.
The traditional peristaltic pump (pipeline pump) sucks or discharges liquid by moving the dead point of the pipeline. Although it has the characteristics of easy cleaning and disinfection and low cost, it is used because of the large force and fatigue at the dead point of the pipeline. The life is low, and it has defects such as poor fluidity

An infusion pump, comprising a first pump casing, a second pump casing, a main shaft, and a wobble plate assembly, the opposite sides of the first pump casing and the second pump casing are respectively provided with first pipe accommodating grooves for clamping elastic pipes and the second pipe accommodating groove, the main shaft is provided with a first bearing seat and a second bearing seat, and the wobble plate assembly includes a first wobble plate set on the first bearing pedestal and a second wobble plate set on the second bearing pedestal plate, the first wobble plate is provided with a first convex part matching with the first pipeline accommodating groove, the second wobble plate is provided with a second convex part matched with the second pipeline accommodating groove, the first wobble plate and the second pipeline accommodating groove are provided with There is a distance between the two wobble plates, if the center line of the first wobble plate is L 1 , The center line of the second swing plate is L 2 , the axis of rotation of the spindle is L 3 , then L 1 , L 2 respectively with L 3 Intersect and L 1 and L 2 is a non-planar straight line. The invention has the advantages of simple and reliable structure, reducing the friction between the convex part and the corresponding elastic pipe, eliminating the friction on the inner wall of the elastic pipe, prolonging the service life of the pump and the like.
Description
technical field [0001] The invention relates to a liquid pump, in particular to an infusion pump. Background technique [0002] A pump is a machine that transports or pressurizes a liquid. It transfers the mechanical energy of the prime mover or other external energy to the liquid to increase the energy of the liquid. Pumps are widely used to transport liquids such as water, oil, acid and alkali liquids, emulsions, suspoemulsions and liquid metals, as well as liquids, gas mixtures and liquids containing suspended solids. Traditional pumps include centrifugal pumps, diaphragm pumps, piston pumps, peristaltic pumps, etc. In chemical, food, pharmaceutical, bioengineering and other fields, there are high requirements for flow pulsation and flow accuracy, but traditional pumps cannot fully meet the requirements, and product quality cannot be guaranteed during use. The traditional peristaltic pump (pipeline pump) sucks or discharges liquid by moving the dead point of the pipeli...
