Problems solved by technology

Its disadvantages are: with the increase of use time, the elastic hose will appear elastic decline, aging, damage, etc., so it must be replaced regularly. When replacing, the upper pump casing and the lower pump casing must be completely disassembled. It is not convenient to reassemble after the tube replacement is completed

Abstract

The invention discloses a liquid conveying pump with pipelines easy to replace. The liquid conveying pump comprises a first pump casing, a second pump casing, locking pieces for locking the first pumpcasing and the second pump casing, an eccentric spindle assembly which is arranged between the first pump casing and the second pump casing and can move axially as well as a swinging disk assembly mounted on the eccentric spindle assembly; a first pipeline accommodating groove and a second pipeline accommodating groove which are used for clamping elastic pipelines are formed in the opposite sidesof the first pump casing and the second pump casing; a first elastic piece is arranged between one end of the eccentric spindle assembly and the first pump casing in an abutting manner; and a secondelastic piece is arranged between the other end of the eccentric spindle assembly and the second pump casing in an abutting manner. The liquid conveying pump has the advantages of simple and reliablestructure, capability of replacing the pipelines easily and the like.

Description

technical field [0001] The invention relates to a liquid pump, in particular to an infusion pump which is easy to replace pipelines. Background technique [0002] A pump is a machine that transports or pressurizes a 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. Patent document CN 110425121 A discloses a uniform-flow pipeline pump, which includes a pump casing with a cylindrical inner cavity, and an annular pipeline accommodating cavity is provided on the side wall of the cylindrical inner cavity. There is a pipeline inlet and outlet connected with the pipeline accommodating ca...
