한편 도 1 및 도 2는 종래 부스터 펌프를 도시한 것으로, 액츄에이터(10a)에 의해 스크류(1a)가 회전하면 스크류(1a)에 결합하고 있는 너트부(2a)가 상하 운동을 하게 되고, 너트부(2a)와 결합하고 있는 플런저(3a)가 동시에 상하운동을 하면서 챔버(120a) 내부의 액을 충진하거나 토출하게 된다.1 and 2 illustrate a conventional booster pump. When the screw 1a is rotated by the actuator 10a, the nut part 2a coupled to the screw 1a moves up and down, and the nut part The plunger 3a coupled to 2a simultaneously fills up or discharges the liquid inside the chamber 120a while vertically moving.
부스터 펌프의 액 충진구와 토출구에는 제어장치로부터 지령에 따라 열고 닫을 수 있는 충진 밸브(4a)와 토출 밸브(5a)가 각기 구비되어 액츄에이터(10a)에 의해 스크류(1a)가 회전하고, 따라서 너트부(2a)와 결합하고 있는 플런저(3a)가 동시에 상승할때 충진구 측의 충진 밸브(4a)가 열리면서 액이 챔버(120a) 내부로 들어온다. The filling and discharging ports of the booster pump are respectively provided with a filling valve 4a and a discharge valve 5a which can be opened and closed according to instructions from the control device, so that the screw 1a is rotated by the actuator 10a. When the plunger 3a engaging with (2a) rises at the same time, the filling valve 4a on the filling port side is opened and the liquid enters the chamber 120a.
액이 채워지는 상사점에 이르면 제어장치에 의해 충진 밸브(4a)는 닫히고 액츄에이터(10a)는 역회전을 시작하면서 너트부(2a)와 플런저(3a)를 동시에 하강시키게 되는데 제어장치에 의해 토출 밸브(5a)가 열리면서 충진된 내부의 액이 토출구(32a)를 통하여 토출하게 된다. The filling valve 4a is closed by the control device when the top dead center where the liquid is filled, and the actuator 10a starts the reverse rotation while simultaneously lowering the nut part 2a and the plunger 3a. 5a is opened, and the filled liquid is discharged through the discharge port 32a.
토출이 끝나는 하사점에서 다시 제어장치에 의해 토출 밸브(5a)는 닫히고 액츄에이터(10a)는 역회전하여 플런저(3a)를 상승시키게 되는데 마찬가지로 제어장치에 의해 동시에 충진 밸브(4a)가 열리면 액이 충진되는 과정을 반복하게 된다. At the bottom dead center where the discharge is completed, the discharge valve 5a is closed by the control device and the actuator 10a is reversely rotated to raise the plunger 3a. Similarly, when the filling valve 4a is opened by the control device, the liquid is filled. The process is repeated.
도 3은 종래 부스터펌프에서 상기의 점성액을 충진하고 토출하는 과정을 보여주며, 플런저(3a) 끝단과 챔버(120a) 최하단 구석은 항상 액이 접착되어 있거나 고여있게 되어 시간이 경과하면서 변성되어 굳어지게 되어 잔존액 고화물(X)이 남게되고, 이 잔존액 고화물(X)이 점차 크기가 커져 일부가 떨어져 나오게 되면서 토출구(32a)를 막게 되는 문제를 야기한다.

도 4 내지 도 7에 도시된 바와 같이, 본 발명에 따른 고점도 액 이송용 부스터펌프는, 일측에 액츄에이터(미도시)가 장착되고, 타측에는 토출밸브(400)가 형성되며 내부에 챔버(120)가 형성된 바디(100); 상기 바디(100)의 내부에 삽입되며 액츄에이터의 작동에 의해 전진 및 후진되어 압축력과 흡입력을 발생하는 플런저(200); 상기 바디(100)의 일측에 형성되며, 플런저(200)의 전진 및 후진작동에 연동되어 개폐되면서 상기 바디(100)의 내측으로 유체를 공급 또는 차단하는 충진 밸브(300);를 포함하여 구성된다.As shown in Figure 4 to Figure 7, high-viscosity liquid transfer booster pump according to the present invention, an actuator (not shown) is mounted on one side, the discharge valve 400 is formed on the other side chamber 120 in the interior Body 100 is formed; A plunger 200 inserted into the body 100 to move forward and backward by the operation of an actuator to generate a compression force and a suction force; It is formed on one side of the body 100, the filling valve 300 for supplying or blocking the fluid to the inside of the body 100 while opening and closing in conjunction with the forward and backward operation of the plunger 200; .
여기서 상기 충진 밸브(300)는 토출밸브(400)로부터 이격되어 바디(100)의 일측 상부에 형성된 흡입구(130)에 장착된다. 상기 흡입구(130)와 챔버(120)의 연결부위는 모따기 되어 만곡부(140)가 형성된다. Here, the filling valve 300 is spaced apart from the discharge valve 400 is mounted to the suction port 130 formed on one side of the upper portion of the body (100). The connection portion between the suction port 130 and the chamber 120 is chamfered to form a curved portion 140.
충진 밸브(300)에는 외부에 연결되어 유체를 공급하는 유체공급부(미도시)가 구비되며, 유체는 주로 고점도 액이 공급된다. Filling valve 300 is provided with a fluid supply unit (not shown) connected to the outside to supply the fluid, the fluid is mainly supplied with a high viscosity liquid.
바디(100)의 내부에는 챔버(120)가 수직되게 형성되고, 이 챔버(120)에 플런저(200)가 삽입된 상태로 플런저(200)의 상승 또는 하강작동에 의해 충진 밸브(300)를 통한 유체의 흡입 및 압축작동이 유발된다. The chamber 120 is vertically formed in the body 100, and the filling valve 300 is operated by the raising or lowering operation of the plunger 200 while the plunger 200 is inserted into the chamber 120. Suction and compression of the fluid is caused.
바디(100)의 상부 일측에는 흡입구(130)가 형성되며, 흡입구(130)에 통하는 이송로는 충진액 이송로(600)가 나선상으로 바디(100)의 내부에 형성되고, 충진액 이송로(600)의 하단 출구(620)는 시이트(170)에 근접되게 저부에 형성된다. The suction port 130 is formed on one side of the upper part of the body 100, and the transport path through the suction port 130 is formed inside the body 100 in a spiral shape, and the filler fluid transport path ( The bottom outlet 620 of 600 is formed at the bottom in proximity to the sheet 170.
따라서 플런저(200)가 상승하기 시작하면 충진 밸브(300)와 흡입구(130)에 연결된 충진액 이송로(600)의 하단 출구(620)로부터 흡입력이 발생되므로 이에 연동되어 충진 밸브(300)가 열리면서 유체가 챔버(120) 내부로 유입된다. Therefore, when the plunger 200 starts to rise, suction force is generated from the bottom outlet 620 of the filling liquid transport path 600 connected to the filling valve 300 and the inlet 130, so that the filling valve 300 is opened in conjunction with the filling valve 300. Fluid flows into the chamber 120.
여기서 충진액 이송로(600)의 상단, 즉 흡입구(130)와 연결된 부위로부터 하단 출구까지 차있던 액은 챔버(120) 내부로 인입되고, 새로 유입된 액이 충진액 이송로(600)에 충진된다. Here, the liquid filled from the upper end of the filling liquid conveying path 600, that is, the portion connected to the suction port 130 to the lower outlet is introduced into the chamber 120, and the newly introduced liquid is filled into the filling liquid conveying path 600. do.
플런저(200)가 하강하면 챔버(120)에 충진된 유체는 압축되면서 토출밸브(400) 및 노즐(430)을 통해 분사된다. When the plunger 200 is lowered, the fluid filled in the chamber 120 is compressed and injected through the discharge valve 400 and the nozzle 430.
본 실시예에 따르면, 충진 밸브(300)에 연결된 흡입구(130)에 통하며, 바디(100)의 챔버(120)의 내주면에 나선상으로 충진액 이송로(600)가 형성되며, 상기 충진액 이송로(600)의 출구(620)는 상기 토출밸브(400)가 연결되는 토출구(180)에 근접되어 형성된다.According to the present embodiment, the filling liquid conveying path 600 is formed on the inner circumferential surface of the chamber 120 of the body 100 in a spiral manner through the inlet 130 connected to the filling valve 300, and the filling liquid is conveyed. The outlet 620 of the furnace 600 is formed to be close to the discharge port 180 to which the discharge valve 400 is connected.
즉, 챔버(120)의 내주면을 나선상으로 1줄 또는 복수의 줄의 충진액 이송로(600)가 형성되고, 이 충진액 이송로(600)는 챔버(120)의 내주면으로부터 일정 깊이로 파여져 형성되므로, 플런저(200)의 외주면이 지나가면서 플런저(200)가 상승하면서 원주 방향으로 개방되는 이송로로부터 액이 나와 적층이 되면서 충진되고, 아울러 플런저(200)이 하강하면서 챔버(120) 내의 액을 토출함과 동시에 충진액 이송로(600) 내의 유체도 가압하게 되어 유체가 나선상으로 된 충진액 이송로(600)를 통해 최종 출구로 토출되는 효과도 있어 토출밸브(400)에 근접된 저부에 고인 유체를 회전시키면서 토출밸브(400)로 토출하여 챔버(120)의 저부에 잔류물을 남기지 않게 된다. That is, the filling liquid transport path 600 of one row or a plurality of rows is formed on the inner circumferential surface of the chamber 120 in a spiral shape, and the filling liquid transport path 600 is formed by being drilled to a predetermined depth from the inner circumferential surface of the chamber 120. Therefore, as the outer circumferential surface of the plunger 200 passes, the liquid plunges from the transport path opened in the circumferential direction as the plunger 200 rises and is filled while being stacked, and the liquid in the chamber 120 is lowered while the plunger 200 descends. Simultaneously with discharging, the fluid in the filling liquid feeding path 600 is also pressurized, so that the fluid is discharged to the final outlet through the spiral filling liquid feeding path 600. The fluid is discharged to the discharge valve 400 while rotating the fluid so that no residue is left at the bottom of the chamber 120.
한편 상기 플런저(200)의 끝단은 콘(CORN) 형상으로 돌출된 선단부(250)가 형성되고, 상기 플런저(200)의 선단부(250)가 접촉되는 챔버(120)의 저부에는 콘 형상으로 오목하게 시이트(170)가 형성된다. On the other hand, the end of the plunger 200 has a tip portion 250 protruding in the shape of a cone (CORN) is formed, the concave shape in the bottom of the chamber 120 that the tip portion 250 of the plunger 200 is in contact Sheet 170 is formed.
이렇게 플런저(200)의 선단부(250)가 뾰족하게 돌출 형성함으로써 고점도 액이 잔류될 부위의 표면적을 줄이고, 아울러 플런저(200)의 선단부가 밀착되는 챔버(120)의 저부도 콘 형상에 대응되는 시이트(170)가 형성되는데, 상기 시이트(170)의 중심부는 토출밸브(400)와 통하는 토출구(180)가 형성된다.The tip portion 250 of the plunger 200 is sharply protruded to reduce the surface area of the portion where the high viscosity liquid remains, and also the bottom portion of the chamber 120 in which the tip portion of the plunger 200 is in close contact with the cone shape. A 170 is formed, and the discharge port 180 communicating with the discharge valve 400 is formed at the center of the sheet 170.
따라서 시이트(170)의 중심으로 집중되는 고점도 액이 토출통로(180)를 통해 토출되고, 아울러 시이트(170)는 오목하게 요입되어 있으므로 고점도 액이 중심으로 흘러가도록 하여 잔류될 소지를 예방할 수 있고 플런저(200)이 상승하며 액을 충진할 때 플런저(200)의 선단을 돌아가며 이송로(600)이 개방되면서 액을 충진하므로 항상 새로운 액이 상층부에 충진되어 액의 선입선출을 완전하게 이루게 된다. Therefore, since the high viscosity liquid concentrated at the center of the sheet 170 is discharged through the discharge passage 180, and the sheet 170 is recessed concave, the high viscosity liquid flows to the center to prevent the residue from being left. As the 200 rises and fills the liquid, the liquid is filled as the transport path 600 opens while rotating the tip of the plunger 200, so that a new liquid is always filled in the upper layer to completely complete the first-in, first-out of the liquid.
이하 본 발명에 따른 고점도 액 이송용 부스터펌프의 작용을 설명하면 다음과 같다. Hereinafter, the operation of the high viscosity liquid transfer booster pump according to the present invention will be described.
도 7에 도시된 바와 같이(작동순서는 (a)->(i)으로 진행된다.). As shown in Fig. 7 (the operation sequence proceeds from (a)-> (i)).
(a)는 플런저(200)가 최저점에 하강된 상태이며, 액이 완전히 토출된 상태이다.(a) is the state in which the plunger 200 fell to the lowest point, and liquid is discharged completely.
(b)~(h)는 플런저(200)를 상승 작동을 순차적으로 나타낸 도면이며, 상부의 흡입구(130) 및 그에 연결된 이송로의 출구까지 차있던 새로운 액이 챔버(120)의 저부로부터 점차적으로 충진되기 시작한다.(b) ~ (h) is a diagram showing the sequential operation of the plunger 200, the new liquid gradually filled from the bottom of the chamber 120 to the inlet 130 of the upper portion and the outlet of the transport path connected thereto Begins to fill.
화살표는 액 충진 위치를 의미한다. Arrows indicate liquid filling position.
(i)는 (h)단계에서 완전히 충진된 후 플런저(200)가 하강하면서 액의 토출시 실시된다. (i) is performed when the liquid is discharged while the plunger 200 descends after it is completely filled in step (h).
따라서 항상 새로운 액이 충진된 후 토출되는 선입선출 방식을 따르게 되므로 플런저(200)의 끝단에 점성액이 누적되어 점착되지 않도록 씻어주게 된다. Therefore, it always follows the first-in, first-out method of discharging after the new liquid is filled, so that the viscous liquid accumulates at the end of the plunger 200 and is washed away.
아울러 플런저(200)의 하단과 챔버(120)의 시이트(170)를 경사도를 갖는 콘 형상으로 가공함으로써 토출시 액의 잔류가 없이 신속하게 토출될 수 있다. In addition, by processing the lower end of the plunger 200 and the sheet 170 of the chamber 120 into a cone shape having an inclination, it can be quickly discharged without remaining of the liquid during discharge.
