본 고안은 가동중 유량(SPM)을 조절할수 있으며 피스턴후진스프링없이 정량을 할수 있는 피스턴후진스프링 없는(Back spring less) 정량펌프에 관한 것으로 정량펌프의 펌프실 다이어프램 작동피스턴 후진스프링을 없애서 다이어프램을 전진시키는 동력모우터의 가동력을 반으로 줄이고 다이어프램을 전진시키는 피스턴의 압력은 웜기어축판에 편심으로 연결된 볼조인트 연결대의 전,후진거리에 의하여 변경되도록 구성하므로서 피스턴후진스프링으로 인한 제한된 힘을(유량과 압력) 기계적인 힘으로 유량의 량과 압력을 크게 향상시키는 힘을 유지할수 있도록 한 것이다.The present invention relates to a back spring less quantitative pump which can adjust the flow rate (SPM) during operation and can quantify without a piston reverse spring. The pump chamber diaphragm operation of the metering pump eliminates the piston reverse spring to advance the diaphragm. The piston's pressure, which reduces the driving force of the power motor in half and advances the diaphragm, is configured to be changed by the forward and backward distance of the ball joint connecting rod eccentrically connected to the worm gear shaft, thereby limiting the limited force (flow rate and pressure) due to the piston spring. It is to maintain the force that greatly improves the flow rate and pressure by mechanical force.

종래의 정량펌프는 모우터의 동력으로 회전시키는 웜기어축의 캠에 다이어프램 중심후면에 고정시킨 연결로드의 단부를 접촉설치시켜서 캠의 회전에 의하여 다이어프램의 연결로드가 전진작용을 하고 동시에 연결로드 외부와 캠 사이에 탄력설치한 후진스프링의 복귀탄력으로 연결로드가 후진작용하도록 구성한 것이였다.The conventional metering pump is installed by contacting the end of the connecting rod fixed to the center rear surface of the diaphragm to the cam of the worm gear shaft which rotates by the power of the motor. The resilient installation of the reversing springs installed between the connecting rods were configured to reverse the action.

이는 후진스프링을 이용한 정량펌프로서 후진스프링의 반발력에 가중하여 다이어프램로드 피스턴을 밀어야 하는 큰동력이 요구되고 큰정량펌프를 필요로 하는 경우 이에 상응하는 후진스프링을 가지는 펌프를 제작해야 하므로 큰정량펌프의 제작에는 동력모우터의 크기가 커져서 어려움이 따르고 또 정해진 후진스프링의 반발력에 맞추어진 펌프는 정지시키지 않고는 정량조절을 할수 없는 어려움이 있었다.This is a fixed-quantity pump that uses a reversing spring, which requires a large power to push the diaphragm rod pistons to the repulsive force of the reversing spring, and when a large capacity pump is required, a pump having a corresponding reverse spring must be manufactured. In manufacturing, the size of the power motor increased, which made it difficult, and it was difficult to quantitatively control the pump without stopping the pump set to the repulsion force of the predetermined reverse spring.

본 고안은 종래 그와같은 문제점을 감안한 것이며 정량펌프의 가동중 외부에서 손쉽게 유량을 조절할수 있으며 후진스프링을 없애서 다이어프램을 전진시키는 동력모우터의 가동력을 반으로 줄이고 후진스프링으로 인한 제한된 힘을 기계적인 힘으로 유량의 량과 압력을 크게 향상시키는 힘을 유지하는 정량펌프를 제공함에 있다.The present invention takes into account such a problem in the related art, and it is possible to easily adjust the flow rate from the outside while the metering pump is running, and to remove the reverse spring, the driving force of the power motor for advancing the diaphragm is halved and the limited force due to the reverse spring is mechanical. It is to provide a metering pump that maintains the force to greatly increase the flow rate and pressure by force.

또한 본 고안은 웜케이스 내에 웜과 웜기어가 치합회전하도록 설치한 웜기어축 전단부에 웜기어축판을 고정하여 웜과 웜기어의 치합회전에 따라 웜기어축판이 회전할수 있게 하고 또 다이어프램 후면중앙에 연결한 피스턴로드 및 피스턴을 기체케이스에 설치하여 피스턴과 웜기어축판 사이를 볼조인트와 볼조인트 연결대로서 웜기어축판에 대하여 편심으로 연결하여 후진스프링 없이 피스턴이 전,후진 하도록 하고 또 웜케이스 일측 돌출편에 볼조인트를 고정하여 기체 케이스 외부로 노출 설치한 각도조절 나선봉을 핸들로서 돌려틀어서 웜케이스와 웜기어축판의 각도조절을 하게 하여 웜기어축판의 편심회전에 의한 피스턴과 연결된 다이어프램의 요동거리를 조절할수 있도록 구성하므로 가동중 유량조절을 자유로히 할수 있는 정량펌프를 제공하고져 한다.In addition, the present invention secures the worm gear shaft plate to the worm gear shaft front end where the worm and the worm gear are installed in the worm case so that the worm gear shaft plate can rotate according to the rotation of the worm and the worm gear, and the piston rod connected to the center of the diaphragm rear And the piston is installed in the case, and the piston and the worm gear shaft plate are connected to the ball joint and the ball joint eccentrically with respect to the worm gear shaft plate so that the piston can move forward and backward without the reverse spring and the ball joint is fixed to one side of the worm case protrusion. Rotate the angle adjusting spiral rod exposed to the outside of the aircraft case as a handle to adjust the angle of the worm case and the worm gear shaft to adjust the swing distance of the diaphragm connected to the piston by the eccentric rotation of the worm gear shaft. Provides a fixed quantity pump for free flow control The gojyeo.

Piston installed in the fixed pin 16 and the gas case 10 at the center of the rear of the diaphragm 6, in which the check valves 14 and 14 'are internally installed by connecting to the outlet pipe 15'. 18 and the piston rod 19 are assembled and assembled to the motor shaft 20 'of the motor 20 installed in the gas case 10 with a worm case 1 installed therein. The worm shaft 21 is connected to the worm shaft 21 so that the worm 22 in the worm case 1 is supported by the lower shaft 32 of the worm shaft 21, and the worm case 1 is configured to be angle-adjusted in the body case 10. In addition, the worm gear (3) in the worm case (1) is installed on the worm gear shaft (4) to rotate the worm 22 and the worm gear (4) one end of the worm gear shaft (4) exposed to the outside of the worm case (1) worm gear The plate 5 is fixed and between the piston 18 and the worm gear shaft plate 5 as the ball joints 26, 26 'and the ball joint connecting rods 8, 8' and 24 to the worm gear shaft plate 5; The connection was installed eccentrically.

이러한 본 고안은 모우터(20)의 가동으로 동력전달이 되어 웜(22)과 웜기어 (3)가 회전작용하고 또 웜기어축(4)에 고정 설치된 웜기어축판(5)이 따라서 회전을 하게 된다. 또한 웜기어축판(5)이 도 3의 (가)의 도시와같이 웜케이스(1)와 함께 수평상태 일때는 웜기어축판(5)의 회전이 볼조인트(26)(26') 및 볼조인트 연결대(24)(8)(8')로서 연결된 피스턴(18)의 스트로크가 영(0)으로 정지상태가 되고 각도조절 나선봉(29)을 외부의 핸들(31)로 돌려서 웜케이스(1)의 각도조절로 웜기어축판(5)의 각도를 조절하면 도 3의 (나) 및 (다) 도시와 같이 웜기어축판(5)과 피스턴(18) 사이의 볼조인트(26)(26') 및 볼조인트 연결대(24)(8)(8')가 웜기어축판(5)의 편심회전으로 인하여 피스턴(18) 이동거리를 변화시키게 되므로 피스턴로드(19), 피스턴(18) 및 고정핀(16)으로 연결된 다이어프램(6)의 요동거리를 보유케되므로 이때는 다이어프램(6)이 요동작용을 하게 되어 정량을 할수 있게 된다.The present invention is a power transmission by the operation of the motor 20, the worm 22 and the worm gear (3) is rotated and the worm gear shaft plate 5 is fixed to the worm gear shaft (4) is rotated accordingly. In addition, when the worm gear shaft plate 5 is horizontal with the worm case 1 as shown in FIG. 3A, the rotation of the worm gear shaft plate 5 is performed by the ball joints 26 and 26 'and the ball joint connecting rod ( The stroke of the piston 18 connected as 24) (8) (8 ') is stopped at zero (0) and the angle of the worm case 1 is turned by turning the angle adjusting spiral rod 29 to the external handle 31.

The diaphragm connected with the piston rod 19, the piston 18, and the fixing pin 16 because the moving distance of the piston 18 is changed due to the eccentric rotation of the worm gear shaft 5. Since the oscillation distance of (6) is retained, the diaphragm 6 oscillates and thus can be quantified.

이와같이 구성된 본 고안은 기체 케이스(10) 내에 각도조절이 되도록 설치된 웜케이스(1)와 웜기어축(4) 선단에 고정설치된 웜기어축판(3)을 웜케이스(1) 일측 돌출편(27)에 연결된 볼조인트(28), 각도조절봉(29) 및 핸들(31)의 핸들(31)을 돌려서 웜케이스(1)의 각도조절로 웜기어축판(5)의 각도를 조절하여 웜기어축판(5)의 편심회전에 의한 피스턴(18) 및 피스턴로드(19) 이동거리를 변화시켜 피스턴(18)과 피스턴로드(19)에 연결된 다이어프램(6)의 요동거리를 조절하므로 피스턴후진스프링 없이 피스턴후진스프링으로 인한 제한된 힘을 기계적인 힘으로 유량의 량과 압력을 크게 향상시켜 정량 할수 있고 모우터(20)의 가동력을 피스턴후진스프링이 있는 종래의 정량펌프보다 반으로 줄일수 있는 효과가 있다.The present invention configured as described above is connected to the worm case 1 and the worm gear shaft plate 3 fixedly installed at the distal end of the worm case 1 and the worm gear shaft 4 so as to adjust the angle in the body case 10. Eccentricity of the worm gear shaft 5 by adjusting the angle of the worm case 1 by turning the ball joint 28, the angle adjusting rod 29 and the handle 31 of the handle 31. By changing the moving distance of the piston 18 and the piston rod 19 by the rotation, the oscillation distance of the diaphragm 6 connected to the piston 18 and the piston rod 19 is adjusted, thereby limiting the piston back spring without the piston back spring. The force can be quantified by greatly improving the amount and pressure of the flow rate by the mechanical force, and there is an effect of reducing the movable force of the motor 20 by half compared to the conventional metering pump having a piston reverse spring.

또한 다이어프램(6)의 요동거리 조절은 정량펌프의 가동중에도 각도조절 나선봉(29) 외단의 핸들(31)로 조절 이용할수 있으므로 사용상 매우 편리한 효과가 있다.In addition, the oscillation distance of the diaphragm 6 can be adjusted and used by the handle 31 at the outer end of the angle adjusting spiral bar 29 even while the metering pump is in operation.
