Description

액체 정량 이송 펌프 { fluid metering pump }Fluid metering pump

본 발명은 액체의 이송 펌프에 관한 것으로, 더욱 상세하게 설명하면, 하우징 내부로 3개의 이송 롤러가 배열된 회전판을 수장하고, 이송 롤러의 외부를 따라 연질의 이송관을 설치한 후, 일측은 마개에 의해 결합되며, 타측에 설치된 구동 모터에 의해 이송 롤러가 결합된 회전판 전체가 회전함에 따라 이송관 내부의 일정량의 액체가 지속적으로 이송되는 액체 정량 이송펌프에 관한 것이다.The present invention relates to a liquid conveying pump, and in more detail, after storing a rotating plate having three conveying rollers arranged inside the housing, and installing a soft conveying pipe along the outer side of the conveying roller, one side is plugged. It is coupled to, and relates to a liquid metering transfer pump that is continuously transported a certain amount of liquid in the transfer pipe as the whole rotating plate is coupled to the transfer roller by the drive motor installed on the other side.

일반적으로 펌프는, 압력 작용에 의하여 액체나 기체의 유체를 관을 통해서 수송하거나, 저압의 용기 속에 있는 유체를 관을 통하여 고압의 용기 속으로 압송하는 기계를 말하며, 이송되는 유체의 양을 정확하게 제어하기 위한 펌프를 정량 펌프라 한다.Generally, a pump is a machine that transports a liquid or gas fluid through a pipe by a pressure action, or pumps a fluid in a low pressure container into a high pressure container through a pipe, and precisely controls the amount of fluid transferred. The pump for doing this is called a metering pump.

상기 정량 펌프는 종래에 다양한 형태로 시도된 바, 그 중 주로 사용되는 정량 펌프의 일 예를 살펴보면, 실린더 내에 설치된 피스톤의 회전운동과 왕복운동에 의해 작동되는 형태로, 한번의 피스톤 주기에 의해 흡입과 토출이 발생하도록 하여 정량의 액체를 이송하도록 구성된다.The metering pump has been attempted in various forms in the related art. Looking at an example of a metering pump mainly used therein, the metering pump is operated by a rotational motion and a reciprocating motion of a piston installed in a cylinder. And discharging to occur so as to transfer a fixed amount of liquid.

이와 같은 정량 펌프는, 그 구조가 피스톤과 실린더 등으로 구성되되, 피스톤이 1회전 시, 1왕복 운동을 해야함으로써 그 구성이 정교하고 복잡하게 되고, 이로 인해 제작이 난해하여 생산원가가 높은 문제점을 내포하고 있었다.Such a metering pump is composed of a piston, a cylinder, and the like, but when the piston is rotated once, the reciprocating motion is precisely complicated and complicated, which makes the production difficult and the production cost high. It was implicated.

또한, 작동과정에 있어서는 액체의 맥동이 발생하게 되며, 이를 보완하기 위해서는 3개의 실린더를 설치하여 사용해야 하는 문제점이 있었으며, 또 유속을 제어하기 위해서는 펌프헤드 부분의 위치를 변화시켜 피스톤의 왕복운동거리를 조정하여 하는 번거로움을 내포하고 있었다.In addition, the pulsation of the liquid occurs in the operation process, there was a problem to install and use three cylinders to compensate for this, and to control the flow rate to change the position of the pump head portion to adjust the reciprocating movement distance of the piston It was a hassle to adjust.

또한, 이송되는 액체가 화공약품 등의 부식성이 강한 것일 경우, 실린더와 피스톤의 부식은 물론, 이송관의 부식으로 인해 장기간 사용이 불가능한 또 다른 문제점을 내포하고 있었다.In addition, when the liquid to be transported is highly corrosive, such as chemicals, there was another problem that can not be used for a long time due to the corrosion of the cylinder and the piston, as well as the transport pipe.

이에 본 발명은 상기와 같은 문제점을 감안하여 발명한 것으로, 하우징의 내부로 회전판을 결합하되, 회전판에는 3개의 이송 롤러를 안착시키고, 이송 롤러의 외부를 따라 연질의 이송관을 설치한 후, 하우징의 일측은 마개에 의해 결합되며, 타측은 구동 모터가 결합되어 구동 모터의 회전력에 따라 이송 롤러가 안착된 회전판 전체가 회전함으로써 이송관 내부의 액체가 일정량씩 지속적으로 이송됨을 목적으로 한다.Therefore, the present invention was invented in view of the above-mentioned problems. The rotary plate is coupled to the inside of the housing, but the three rotary rollers are seated on the rotary plate, and a soft transfer tube is installed along the outside of the transfer roller. One side of the is coupled by a stopper, the other side is driven by the drive motor is coupled to rotate the entire rotating plate seated on the transfer roller in accordance with the rotational force of the drive motor for the purpose of continuously conveying a constant amount of liquid in the transfer pipe.

또한, 종래의 정량 펌프에 비해 구성이 간단하여 제작시간과 비용이 절약되며, 구동 모터에 공급되는 전류의 양을 조절함으로써 이송되는 액체의 양을 용이하게 조절 가능하여 각종 액체의 정량 이송용 소형 펌프로 적용 가능함을 목적으로 한다.In addition, the configuration is simpler than the conventional metering pump, which saves manufacturing time and cost, and by controlling the amount of current supplied to the drive motor, the amount of liquid to be transferred can be easily adjusted. It is intended to be applicable.

특히, 이송관의 부식을 야기하는 화공약품 등을 이송할 경우에는 연질의 내부식성 고무 재질의 이송관을 사용함으로써 장기간 사용 시에도 부식의 우려가 없으며, 잉크젯프린터용 잉크 카트리지의 충전 시 정량 토출 펌프로 사용이 적합함을 또 다른 목적으로 한다.In particular, when transporting chemicals or the like that cause corrosion of the transport pipe, a soft, corrosion-resistant rubber transport pipe is used, so there is no fear of corrosion even when used for a long time. It is another object that it is suitable for use.

상기 구성을 갖는 본 발명은, 종래의 정량 펌프에 비해 구성이 간단하여 제작시간과 비용이 절약되며, 구동 모터에 공급되는 전류의 양을 조절함으로써 이송되는 액체의 양을 용이하게 조절 가능하여 각종 액체의 정량 이송용 소형 펌프로 유용한 효과가 있다.The present invention having the above-described configuration is simpler than the conventional metering pump, which saves manufacturing time and cost, and easily adjusts the amount of liquid to be transported by adjusting the amount of current supplied to the drive motor. It has a useful effect as a small pump for quantitative transfer of.

특히, 이송관의 부식을 야기하는 화공약품 등을 이송할 경우에는 연질의 내부식성 고무 재질의 이송관을 사용함으로써 장기간 사용 시에도 부식의 우려가 없으며, 잉크젯프린터용 잉크 카트리지의 충전 시 정량 토출 펌프로 사용이 적합한 또 다른 효과가 있다.In particular, when transporting chemicals or the like that cause corrosion of the transport pipe, a soft, corrosion-resistant rubber transport pipe is used, so there is no fear of corrosion even when used for a long time. There is another effect that is suitable for use.
