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
Although traditional diaphragm pumps have good fluidity and longer life than peristaltic pumps, they are complex to manufacture, high in cost, and not conducive to cleaning and disinfection

Abstract

A pipeline membrane pump is provided with a pump case. A cylindrical inner cavity is formed in the pump case. A plurality of arc-shaped pipeline containing cavities are formed in the side wall of the cylindrical inner cavity. An elastic hose is arranged in each of the multiple pipeline containing cavities. The two ends of each elastic hose are connected with a liquid input pipe connector and a liquid output pipe connector correspondingly. One-way valves are arranged at the two ends of each elastic hose. An inclined offset shaft is arranged in the pump case. The outer portion of the inclined offset shaft is connected with swing wheels through third bearings. A flange is arranged on the outer side of each swing wheel and extends to the position between the elastic hoses. When the inclined offset shaft is driven by a motor to rotate, the swing wheels are made to do cone swinging, the elastic hoses are extruded or released through the flanges of the swing wheels, and liquid is discharged out and sucked in one direction in a one-way manner through the one-way valves. The pipeline membrane pump can be manufactured into a single stage or multiple stages and has the beneficial effects of being good in liquid flow state, high in work efficiency, convenient to clean and disinfect, long in service life, low in cost, easy to produce and manufacture and the like.

Description

[0001] 【Technical field】 [0002] The invention relates to a liquid pump, in particular to a pipeline diaphragm pump with simple structure and manufacture, long service life and low production cost. [0003] 【Background technique】 [0004] 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 t...
