Extrusion pumping module and diaphragm fluid supply device using same

Abstract

An extrusion pumping module of the present invention may be formed by combining a plurality of pumping units. Each pumping unit includes, as a plate-shaped member, a plate member which is formed to beinclined toward one side toward the outside with respect to a flow hole opened in the center thereof, a coupling member which is provided such that a pair of plate members overlap each other to forma space therein, and a sealing member disposed between the coupling member and the plate member, wherein the plurality of pumping units may be coupled to each other such that the flow holes can communicate with each other. In addition, the diaphragm fluid supply device of the present invention includes the above-described pumping module, an operating shaft disposed through the communicating flow hole of the pumping module, and a casing provided with an inlet hole into which content is introduced, and an outlet hole through which the content is extruded, and configured to have a space therein formed to communicate with the flow hole on one side of the pumping module such that the content introduced through the inlet hole can flow into an inner space of the pumping module. One end of the operating shaft is coupled by penetrating the pumping module to close the flow hole opposite to the pumping module coupled to the casing, an operation of contracting and expanding the inner space of thepumping module according to a reciprocating movement of the operating shaft is repeated, and a process of introducing the content through the inlet hole and extruding the content through the outlet hole may be repeated.

Description

technical field [0001] The present invention relates to a squeeze suction module and a diaphragm type fluid supply device using the same. Compresses and expands the inner space without any physical interference, is less prone to damage or breakage even when subjected to repeated external forces, and has an extra elastic area for a stronger squeeze effect. Background technique [0002] Generally, a pump (pump) for transferring stored liquid or gas to a predetermined position is widely used. [0003] A pump is a device that conveys a fluid as a liquid or a gas through a pipe by the action of pressure, or pushes the fluid in a predetermined direction by pressure. [0004] In this case, the pressure for pumping the fluid can be generated in a number of ways. [0005] Depending on the method of pressure generation, reciprocating pumps using pistons or plungers, rotary pumps that convert rotational force into linear motion to reciprocate pistons, centrifugal pumps that transfer ...

AI Technical Summary

Problems solved by technology

[0009] However, the technique as described above has the disadvantage that since the bellows member that repeatedly shrinks and expands is made of metal, the amount of paint discharged per unit time is relatively low in terms of the characteristics of the metal, although a strong discharge pressure is obtained. few

[0010] In addition, there are also disadvantages in that the possibility of fatigue failure due to repeated shrinkage and expansion is high, resulting in a short life, and in order to prevent damage to the bellows parts, it is necessary to bond a wide area more tightly by welding
