Description

정밀유량제어에 적용되는 로타리 피스톤 펌프를 사용하는 구성요소와 연결방식.{Flow Control System with Rotary Pistion Pump}Components and connection method using rotary piston pump for precision flow control. {Flow Control System with Rotary Pistion Pump}

발명은 특허청구범위 제1항에 전제부에 따르는 정밀유량제어에 적용되는 로타리 피스톤 펌프(rotary piston pump)를 사용하는 구성요소와 연결방식에 관한 것이다.The invention relates to a component and a connection method using a rotary piston pump applied to precision flow control in accordance with the preamble of claim 1.

펌프 헤드(도 2)는 피스톤의 상하왕복운동과 회전운동을 통해 매질의 펌핑(Pumping)작용과 입출력 개ㆍ페 기능을 동시에 처리하는 구조로 되어 있다. 상ㆍ하왕복운동은 유체나 공압과 같은 매질의 압력차를 발생시키고 회전운동은 피스톤 홈(D-Cut)의 각도별 위상차에 의해 입력과 출력 구멍의 개폐기능을 회전각도에 따라 순차적으로 일어나게 한다. 피스톤 상ㆍ하 왕복운동시에 최대, 최소 stroke의 상대위치 변이는 실린더 중심축과 원동축 간의 각도 차이가 증가함에 따라 그 크기가 선형적으로 증가한다.The pump head (FIG. 2) has a structure which simultaneously processes the pumping action and the input / output opening / closing function of the medium through the up and down and the reciprocating motion of the piston. The up / down reciprocating motion generates the pressure difference of the medium such as fluid or pneumatic, and the rotational motion causes the opening and closing function of the input and output holes to be sequentially made according to the rotation angle by the phase difference of the piston groove (D-Cut). . In piston up / down reciprocation, the relative position shift of the maximum and minimum stroke increases linearly as the angle difference between the cylinder center axis and the driving axis increases.

동력전달부분(도 6)은 원동축의 회전운동을 피스톤의 상하왕복운동과 회전운동으로 변환하는 기능을 수행하는 구조로 만들어진다. 피스톤은 구명베어링의 중심을 관통하는 내경원에 피스톤의 축 중심과 직각인 핀으로 연결되어 Rotate, Yaw, Rolling, Sliding 운동이 일어나면서 펌프 헤드내에서 회전과 상하왕복운동을 수행하게 된다.The power transmission part (Fig. 6) is made of a structure that performs the function of converting the rotational movement of the circular shaft to the reciprocating and rotating movement of the piston. The piston is connected to the inner diameter circle passing through the center of the life bearing by a pin perpendicular to the center of the piston, and rotates, yaws, rolls, and slides to perform rotation and up and down movement in the pump head.

메인 베이스(도 5)는 원동기에서 전달된 힘으로 원활한 펌프 작용을 하는 각 부분을 고정해주는 기능을 목적으로 한다. 펌프 헤드는 원동축과 각도가 기울어지게 체결된다. 기울어진 각도에 따라 회전당 유량값이 정해진다.The main base (FIG. 5) aims to fix each part of the smooth pumping action by the force transmitted from the prime mover. The pump head is fastened at an angle to the driving shaft. The angle of inclination determines the flow rate per revolution.

본 발명은 국내 특허출원번호 10-2004-0013230과 20-2002-0012716과 같은 튜빙 펌프과 같은 정밀유량제어를 목적으로 제작된 펌프이다. 튜빙 펌프는 튜브로 관을 롤러로 회전시키면서 유량의 이송시킨다. tube에 가해지는 롤러의 외압과 반복적인 형상변경은 tube 내경의 크기와 탄력성 저하를 야기한다. 따라서 점진적으로 롤러와 맞닫은 tube는 변형에 의해 단시간내에 토출되는 유량값이 변한다. 그와 더불어 높은 온도와 내화학적 특징을 만족시키기에는 tube를 구성하는 물질의 종류와 사용시간에 의해 많은 제약이 있게 된다. 본 발명 로타리 피스톤 펌프는 피스톤과 실린더가 모두 세라믹 재질로 구성되어 기본적인 내화학성과 내열성, 내마모성이 매우 우수하다. 또한 펌프 헤드(도 2)의 재질을 내화학성이 우수한 재질의 금속으로 구성할 수 있어 tubing pump와 차별되는 상황에서 사용할 수 있다.The present invention is a pump produced for the purpose of precise flow control, such as tubing pumps such as domestic patent applications No. 10-2004-0013230 and 20-2002-0012716. The tubing pump transfers the flow rate as the tube is rotated by a roller with a tube. The external pressure and repeated shape change of the roller applied to the tube causes a decrease in size and elasticity of the tube inner diameter. Therefore, the flow rate value discharged within a short time due to the deformation of the tube which is gradually in contact with the roller. In addition, there are many limitations to satisfy the high temperature and chemical resistance by the type of material and the time of use. Rotary piston pump of the present invention, both the piston and the cylinder is made of a ceramic material is very excellent in basic chemical resistance and heat resistance, wear resistance. In addition, the material of the pump head (FIG. 2) may be made of a metal having excellent chemical resistance, and thus may be used in a situation that is different from the tubing pump.

우수한 내열, 내마모성, 내화학적 특징을 지닌 세라믹으로 실린더와 피스톤을 만들고, 유량별 요구사항에 따라 펌프 헤드 체결 각도를 설계하였다. 그리고, 원동기가 분당 회전하는 속도를 가변적으로 적용하면 원동기의 회전속도에 따라 폭넓은 유량값을 정밀하게 제어할 수 있다.Cylinders and pistons were made from ceramics with excellent heat, wear and chemical resistance, and pump head tightening angles were designed according to flow-specific requirements. In addition, if the speed at which the prime mover rotates per minute is variably applied, it is possible to precisely control a wide flow rate value according to the prime mover speed.

In addition, if the speed at which the prime mover rotates per minute is variably applied, it is possible to precisely control a wide flow rate value according to the prime mover speed.

세라믹으로 만들어진 피스톤과 실린더의 펌프 헤드는 요구되는 유량값에 맞게 정확히 계산된 각도로 가공 후 체결되어 진다. 체결된 펌프 헤드의 피스톤은 원동기의 원운동을 전달받아 피스톤의 상하 운동과 회전운동을 하게 되고, 입력과 출력 포트의 순차적인 개폐 과정상에서 유량의 흡입과 토출이 동시에 진행된다. 유량에 따른 펌프 헤드, 펌프 헤드의 체결 조건의 설계 및 가장 심플한 구조와 요소로 구성하는 것이 본 발명의 내용이다.The piston and cylinder pump heads made of ceramic are tightened after machining at precisely calculated angles to meet the required flow values. The piston of the coupled pump head receives the circular motion of the prime mover to perform vertical movement and rotational movement of the piston, and the suction and discharge of the flow rate are simultaneously performed in the sequence of opening and closing the input and output ports. It is the content of the present invention to design the pump head according to the flow rate, the design of the fastening conditions of the pump head, and to constitute the simplest structure and elements.
