본 고안은 오수처리 또는 식품제조시에 첨가되는 액상의 화학제나 약제등을 일정량 주입할 수 있도록 한 다이어 프램식 정량펌프를 구성함에 있어서 약액의 펌핑량을 손쉽게 조절하면서도 다이어 프램을 작동시키는 캠과 로드의 내구성을 향상시키고 마모율을 최대한 감소시켜서 펌프의 수명을 연장시킬 수 있도록 한 고안에 관한 것이다.The present invention is to construct a diaphragm metering pump that can inject a certain amount of liquid chemicals or drugs added during sewage treatment or food manufacturing, cam and rod to operate the diaphragm while easily adjusting the pumping amount of the chemical liquid The invention relates to a device designed to extend the life of the pump by improving the durability and reducing the wear rate as much as possible.

일반적으로 다이어프램식 정량펌프는 모터의 축에 캠이 형성된 캠축을 연설하여 모터로 회동되는 캠이 스프링으로 탄지되는 다이어 프램의 로드를 타격함에 따라 다이어 프램이 펌핑 작동되면서 정량의 약액을 주입하도록 되어있다.In general, the diaphragm metering pump speaks a camshaft with a cam formed on the shaft of the motor, and the diaphragm is pumped to inject a fixed amount of chemical liquid as the cam rotated by the motor strikes the rod of the diaphragm carried by the spring. .

그런데 상기한 종래의 정량펌프는 모터로 회동되는 캠축의 캠이 직접 다이어프램의 로드를 회전 타격하여 작동시켜 주거나 캠의 외주연에 꼭맞는 베어링을 씌워서 베어링의 외주연으로 다이어 프램의 로드를 전후직선 방향이 아닌 상하 전후방향으로 타격하여 작동시켜주기 때문에 그 충격으로 인해 소음이 크면서도 약액의 펌핑량을 조절하기 힘들고 캠과 로드의 내구성이 떨어지며, 마모율이 심해서 장시간 사용할때 약액의 정량주입이 점차 어렵게 됨에 따라 정량 펌프로서의 기능을 원활히 수행할 수가 없음은 물론 펌프수명이 짧게 되는 폐단이 있었다.However, in the conventional metering pump, the cam of the cam shaft rotated by the motor is operated by directly hitting the rod of the diaphragm, or the bearing is fitted to the outer periphery of the cam so that the rod of the diaphragm is moved forward and backward in the direction of the bearing. Because it is operated by hitting up and down and up and down directions, it is difficult to control the pumping amount of the chemical liquid due to the noise, and the durability of the cam and rod is reduced, and the wear rate is severe, which makes it difficult to quantify the chemical liquid for a long time. As a result, there was a closed end that the pump life could not be smoothly performed as well as the pump life was short.

본 고안은 이와같은 종래의 폐단을 감안하여 캠과 로드의 마모율 감소와 내구성을 향상시켜서 펌프수명을 최대한 연장시킬수 있도록 창안된 것인바 이를 첨부된 도면에 의해 상세히 설명하면 다.음과 같다.The present invention is designed to extend the life of the pump as much as possible by reducing the wear rate and durability of the cam and rod in consideration of the conventional closed end, which will be described in detail with reference to the accompanying drawings.

모터(3)의 축에 연설된 캠축(4)의 캠(5) 또는 캠의 외주연으로 베어링이 씌워진 캠이 스프링(8)으로 탄지되는 다이어프램(7)의 로드(6)를 타격하여 약액을 펌핑하도록 된 정량펌프에 있어서 케이스(1)의 내부상하면에 가이드편(9)(9a)을 형성한후 캠축(4)의 캠(5)외주면에 베어링(10)을 축설하되 내측레이스(11)는 캠(5)과의 유격(ℓ)이 케이스(1)일측에 설치된 조절구(13)에 의해 조절되게 하고 베어링(10)의 외측레이스(12)는 상하의 가이드편(9)(9a) 사이에 접면된 상태에서 로드(6)를 작동시키도록 한 것으로서 도면중 미설명 부호(14)는 펌프헤드(2)의 유입구이고, (15)는 배출구이며, (16)은 볼시트, (17)은 역지변용 체크볼이고 (18)은 와셔이며, (13a)는 조절구(13)의 선단이다.The cam 5 of the cam shaft 4 extended to the shaft of the motor 3 or a cam bearing the outer periphery of the cam hits the rod 6 of the diaphragm 7, which is carried by the spring 8, and the chemical liquid is discharged. In the fixed-quantity pump to be pumped, the guide pieces 9 and 9a are formed on the upper and lower surfaces of the case 1, and then the bearing 10 is laid on the outer peripheral surface of the cam 5 of the cam shaft 4, but the inner race 11 The clearance (l) with the cam (5) is adjusted by the adjusting opening 13 installed on one side of the case (1) and the outer race 12 of the bearing 10 is between the upper and lower guide pieces (9) (9a) In the drawing, the rod 6 is operated in a state in which it is contacted with reference numeral 14, which is an inlet port of the pump head 2, 15 is an outlet port, and 16 is a ball seat, 17. Is a check valve for reverse displacement, 18 is a washer, and 13a is the front end of the adjuster 13.

이와같이 형성된 본 고안은 모터(3)에 의해 캠축(4)이 회전되면 캠(5)이 회동하여 베어링(10)의 내측레이스(11)를 밀어줌에 따라 측레이스(12)가 다이어프램(7)의 로드(6)를 밀어서 작동시켜주는 것이다.According to the present invention formed as described above, when the cam shaft 4 is rotated by the motor 3, the side race 12 is diaphragm 7 as the cam 5 rotates to push the inner race 11 of the bearing 10. The rod (6) is to operate by pushing.

즉, 캠(5)이 캠축(4)을 중심으로 제 3 도의 이점쇄선과 같이 후진될 때에는 캠(5)과 내측레이스(11)사이의 유격(ℓ)이 앞쪽(로드(6)방향쪽)에 있게 되므로 베어링(10)은 유격(ℓ)만큼 뒤로(조절구(13) 방향으로) 밀릴 수 있는 상태가 된다.That is, when the cam 5 is retracted about the camshaft 4 as shown by the dashed-dotted line of FIG. 3, the clearance l between the cam 5 and the inner race 11 is forward (in the direction of the rod 6). Since the bearing 10 is in a state that can be pushed back (in the direction of the adjuster 13) by the play (L).

이에따라 로드(6)가 스프링(8)의 힘에 의해 뒤로 탄발되면서 다이어프램(7)을 당겨주므로 약액은 상하의 볼시트(16) 및 체크볼(17) 작용에 의해 유입구(14)를 통해 펌프헤드(2)내로 유입되는 것이며, 상기와 같이 로드(6)가 스프링(8)에 의해 탄발되어 뒤로 밀리는 힘에 의해 베어링(10)은 상하의 가이드편(9)(9a)에 접면된 상태에서 수평이동하여 제 3 도의 이점쇄선과 같이 조절구(13)의 선단(13a)에 닿게된다.Accordingly, the rod 6 is pulled back by the force of the spring 8 and pulls the diaphragm 7, so that the chemical liquid is pumped through the inlet port 14 through the action of the upper and lower ball seats 16 and the check ball 17. 2) It is introduced into the inside, and the bearing 10 is horizontally moved in contact with the upper and lower guide pieces 9 and 9a by the force of the rod 6 being pushed back by the spring 8 and pushed back as described above. Like the dashed-dotted line of FIG. 3, it comes in contact with the front-end | tip 13a of the control opening 13. FIG.

그후 캠(5)이 제 3 도의 실선과 같이 전진 회동되면 캠(5)이 베어링(10)의 내측레이스(11)를 밀어서 상하의 가이드편(9)(9a)에 접면된 베어링(10)을 수평으로 전진시켜 줌에따라 베어링(10)의 외측레이스(12)가 로드(6)를 눌러주는 것이며, 이에따라 로드(6)는 스프링(8)을 압축하면서 다이어프램(7)을 밀어주어 펌프헤드(2)내에 유입된 약액이 배출구(15)로 배출되게 하는 것이다.Then, when the cam 5 is rotated forward as shown by the solid line in FIG. 3, the cam 5 pushes the inner race 11 of the bearing 10 to horizontally align the bearing 10 which is in contact with the upper and lower guide pieces 9, 9a. As the outer race 12 of the bearing 10 presses the rod 6 as it moves forward, the rod 6 pushes the diaphragm 7 while compressing the spring 8 so that the pump head 2 The chemical liquid introduced into the) is to be discharged to the outlet (15).

이러한 본 도안은 조절구(13)의 선단(13a)을 케이스(1)내에 진입시키는 정도에 따라 약액의 펌핑량이 손쉽게 조절되는 것으로서 즉, 조절구(13)의 선단(13a)을 깊숙히 진입시켜 베어링(10)을 밀어주면 베어링(10)은 유격(ℓ) 범위내에서 밀리게 되며, 이와같이 베어링(10)이 밀리면 베어링(10)에 접면된 로드(6)가 따라 밀린상태(전진된 상태)에서 다이어프램(7)이 작동되므로 다이어프램(7)의 작동행정이 적게되어 흡입과 배출되는 약액의 량이 감소되는 것이고, 반대로 조절구(13)의 선단(13a)을 후진 시켜주면 그만큼 스프링(8)으로 탄발되는 로드(6)가 베어링(10)을 밀면서 함께 후진된 상태에서 다이어프램(7)의 작동행정을 크게 작동시켜 주므로 흡입과 배출되는 량이 많아지는 것으로서 조절구(13)에 의해 약액의 주입량을 펌프 가동중에도 조절할 수가 있다.The present figure is that the pumping amount of the chemical liquid is easily adjusted according to the degree of entering the front end (13a) of the adjusting device 13 in the case (1), that is, the bearing (13) deeply enters the front end (13a) of the adjusting device (13) When the bearing 10 is pushed, the bearing 10 is pushed in the play (ℓ) range. Thus, when the bearing 10 is pushed, the rod 6 which is in contact with the bearing 10 is pushed along (advanced state). Since the diaphragm 7 is operated, the operation stroke of the diaphragm 7 is reduced, so that the amount of inhaled and discharged chemicals is reduced. Since the rod 6 being pushed back along with the bearing 10, the operation stroke of the diaphragm 7 is greatly operated, so that the amount of intake and discharge is increased, and the injection amount of the chemical liquid is pumped by the regulator 13. I can adjust it in the middle.

그리고 종래와 같이 로드(6)를 캠(5)이 직접 선접촉하며 타격 작동시키는 것이 아니라 캠(5)이 점접촉되는 베어링(10)을 직선으로 밀어서 로드(6)를 작동시키는 것이기 때문에 즉, 로드(6)가 타격에 의해 작동되는 것이 아니라 베어링(10)의 구동력과 상하의 가이드편(9)(9a)에 의해 부드럽게 직선으로 왕복 운동하는 베어링(10)에 의해 수평으로 밀려서 로드(6)가 작동되는 것이기 때문에 작동시 소음이 적고 캠과 로드의 내구성이 뛰어나면서도 마모율이 별로 없어서 펌프의 수명을 최대한 연장시킬 수 있는 매우 유용한 고안인 것이다.Since the cam 5 is not in direct contact with the cam 5 and hits the rod 6 as in the related art, the rod 6 is pushed in a straight line to operate the rod 6. The rod 6 is not driven by the hitting but is horizontally pushed by the bearing 10 which reciprocates smoothly and linearly by the driving force of the bearing 10 and the upper and lower guide pieces 9 and 9a. It is a very useful design that can extend the life of the pump as much as possible because of its low noise, excellent durability of the cam and rod, and low wear rate.
