도 6a와 6b는 본 고안에 따른 실시 예로써 여과펌프(3)의 토출압력에 의하여 발생하는 유체의 흐름과 개폐판(5)의 이동을 보여주는 도면으로 도 6a에서와 같이 여과펌프(3)가 정상적으로 작동하면 토출압력에 의하여 개폐판(5)은 스프링(6)을 압축하며 화살표 방향으로 유체의 흐름이 발생한다. 6A and 6B are views showing the flow of the fluid generated by the discharge pressure of the filtration pump 3 and the movement of the opening and closing plate 5 as an embodiment according to the present invention. As shown in FIG. 6A, the filtration pump 3 When normally operated, the opening / closing plate 5 compresses the spring 6 due to the discharge pressure, and a flow of the fluid is generated in the direction of the arrow.

이때 펌프 흡입구의 막힘, 여과해야할 액의 부족으로 여과펌프(3)의 토출압력이 저하될 경우에는 도 6b와 같이 스프링(6)의 탄성에 의하여 개폐판(5)은 몸체(2)의 입구를 막아 유체의 흐름이 정지하게 된다.When the discharge pressure of the filtration pump 3 is lowered due to the clogging of the pump suction port and the lack of the liquid to be filtered, the opening / closing plate 5 is moved by the elasticity of the spring 6 as shown in FIG. The flow of the fluid stops.

도 7a와 7b는 유체의 흐름에 따라 개폐판(5)의 이동에 의하여 무전원 접점이 구성되는 것을 보여주는 도면으로 도 7a와 같이 여과펌프(3)의 정상작동에 의하여 토출압력이 발생하면 개폐판(5)이 스프링(6)을 압축하여 전도체인 가동접점(11)과 고정접점(10) 접촉하여 여과펌프(3)가 정상적으로 작동하고 있다는 신호를 발생하며, 펌프 흡입구의 막힘, 여과해야할 액의 부족으로 여과펌프(3)의 토출압력이 저하되면 유체의 흐름이 정지되고 스프링(6)의 탄성에 의하여 계폐판(5)이 복귀되고 전도체인 가동접점(11)과 고정접점(10)이 분리되어 여과펌프(3)의 고장을 방지하기 위한 이상감지 신호를 발생하게 된다. 7A and 7B are diagrams showing that the non-power source contact is formed by the movement of the opening / closing plate 5 according to the flow of the fluid. When the discharge pressure is generated by the normal operation of the filtration pump 3 as shown in FIG. 7A, 5 generates a signal indicating that the filtration pump 3 is operating normally by contacting the movable contact 11 and the stationary contact 10 by compressing the spring 6 to cause clogging of the pump suction port and lack of liquid to be filtered When the discharge pressure of the filtration pump 3 is lowered, the flow of the fluid is stopped and the movable plate 5 is returned by the elasticity of the spring 6 and the movable contact 11 and the stationary contact 10 are separated from each other Thereby generating an abnormality detection signal for preventing the failure of the filtration pump 3.
