본 발명의 일 실시예에 따른 진공형 볼류트펌프(1000)는, 도 1 내지 도 7에 도시된 것과 같이, 일측에 엔진(A)에 연결되고 하부에 베이스프레임(B)에 고정된 단단볼류트펌프(1100)과, 이 단단볼류트펌프에 연결되어 지하의 물이 유입되도록 된 양단에는 플랜지가 구비된 유입진공하우징(1200)과, 상기 단단볼류트펌프(1100) 또는 유입진공하우징(1200)의 상부에 설치되어 진공상태로 흡입함과 더불어 양정되는 물을 감지하도록 센서(1310)가 구비된 진공액체감지부(1300)와, 상기 베이스프레임에 고정된 진공펌프(1400)와, 이 진공펌프의 작동에 의해 진공액체감지부로 진공흡입하도록 진공펌프와 진공액체감지부에 연결설치된 진공흡입라인(1500)과, 상기 볼류트펌프의 상부에 설치되어 일정압력으로 액체가 유입되면 열리도록 된 체크밸브(1600)와, 상기 진공펌프와 진공액체감지부를 조작하도록 된 조작부(1700)로 이루어진다.Vacuum type volute pump 1000 according to an embodiment of the present invention, as shown in Figure 1 to 7, a single stage ball is connected to the engine (A) on one side and fixed to the base frame (B) at the bottom A lute pump 1100, an inlet vacuum housing 1200 provided with a flange at both ends connected to the single stage volute pump, and having underground water introduced therein, and the single stage volute pump 1100 or the inlet vacuum housing 1200 And a vacuum liquid detecting unit 1300 provided with a sensor 1310, a vacuum pump 1400 fixed to the base frame, and installed at an upper portion of the upper portion thereof to suck water in a vacuum state and to lift water which is lifted. The vacuum suction line 1500 connected to the vacuum pump and the vacuum liquid detecting unit to suck the vacuum into the vacuum liquid detecting unit by the operation of the pump, and the check installed to be opened when the liquid flows at a constant pressure installed on the upper portion of the volute pump. Valve 1600, the vacuum pump and the vacuum Made of the operation unit 1700 to the operation unit detects the liquid.

따라서 상기 조작부(1700)를 조작하여 진공펌프(1400)가 동작하게 되면 진공흡입라인(1500)과 진공액체감지부(1300) 및 유입진공하우징(1200)을 통해서 진공을 이루어 지면 아래쪽의 물을 양정하여 유입진공하우징(1200)에 물이 찰 때까지 진공상태가 유지된 상태로, 상기 진공액체감지부(1300)에서 유입진공하우징(1200)에 물이 채워진 것을 센서(1310)가 감지하게 되면 진공펌프(1400)의 동작이 멈추게 되고, 이렇게 진공펌프(1400)가 동작을 멈춘 것을 확인한 작업자가 엔진(A)을 가동하게 되면 단단볼류트펌프(1100)와 상부로 연결된 체크밸브(1600)가 열리면서 단단볼류트펌프(1100)에 의해 물이 멀리까지 압송되게 된다.Therefore, when the vacuum pump 1400 is operated by operating the operation unit 1700, the vacuum is drawn through the vacuum suction line 1500, the vacuum liquid detecting unit 1300, and the inlet vacuum housing 1200 to lift the water below the surface. When the vacuum state is maintained until the water is filled in the inlet vacuum housing 1200, the vacuum liquid detecting unit 1300 detects that the water is filled in the inlet vacuum housing 1200. When the operation of the pump 1400 is stopped and the operator who confirms that the vacuum pump 1400 stops operating the engine A operates, the check valve 1600 connected to the single stage volute pump 1100 is opened. Water is pumped to a far distance by the single stage volute pump 1100.

여기서 상기 유입진공하우징(1200)은, 축방향으로 관통된 관통구멍(1211)이 형성됨과 더불어 축방향 외부면에서 내부로 관통되도록 설치된 축관(1210)과, 이 축관(1210)의 양측 축방향으로 양단에 용접되어 다른 축관부재와 연결할 수 있도록 제1,2플랜지(1221,1222)로 이루어진 플랜지(1220)를 구비한다.Here, the inflow vacuum housing 1200 has a through hole 1211 formed in the axial direction, and is provided with a shaft tube 1210 installed so as to penetrate from the outer surface in the axial direction, and the shaft tube 1210 in both axial directions.

Will be sucked up in a vacuum.

상기 센서감지부(1350)의 센서(1351)는, 상기 유입진공하우징(1320)내부의 물을 3가지의 높이로 진공펌프(1400)의 작동을 멈추도록 된 만수위감지봉(1351a)과, 물이 감지되지 않으면 지속적으로 진공펌프(1400)를 작동시키도록 신호를 보내도록 된 급수감지봉(1351b) 및 물이 감지되면 기준수위를 인식하도록 제어신호를 보내도록 된 수위기준감지봉(1351c)으로 이루어진다.The sensor 1351 of the sensor detecting unit 1350 includes a water level sensing rod 1351a which stops the operation of the vacuum pump 1400 at three heights of the water inside the inflow vacuum housing 1320. If it is not detected by the water supply detection rod (1351b) to continuously send a signal to operate the vacuum pump 1400 and the water level reference detection rod (1351c) to send a control signal to recognize the reference level when water is detected. Is done.

따라서 상기 만수위감지봉(1351a)과 급수감지봉(1351b) 및 수위기준감지봉(1351c)으로 이루어진 센서(1351)에 의해 유입진공하우징(1320)내부의 수위를 감지하여 진공펌프(1400)의 동작을 제어하게 되고, 이 진공펌프(1400)가 정지되면 상기 엔진(A)를 작업자가 작동시키게 되고, 이때 상기 단단볼류트펌프(1100)가 동작되면서 물을 체크밸브(1600)쪽으로 압송시키게 된다.Therefore, the water level inside the inlet vacuum housing 1320 is detected by the sensor 1351 including the water level sensing rod 1351a, the water supply sensing rod 1351b, and the water level reference sensing rod 1351c to operate the vacuum pump 1400. When the vacuum pump 1400 is stopped, the operator operates the engine A. At this time, the single-stage volute pump 1100 is operated to pressurize water toward the check valve 1600.

또한 상기 체크밸브(1600)는 단단볼류트펌프(1100)의 작동에 의해 상측으로만 물이 압력에 의해 압송되도록 구성되어 있고, 측면으로 체크밸브(1600)에 남아 있는 물을 선택적으로 배수할 수 있도록 배수밸브(1610)가 설치되어 있다.In addition, the check valve 1600 is configured such that water is pumped upward by pressure only by the operation of the single-stage volute pump 1100, and can selectively drain the water remaining in the check valve 1600 to the side. The drain valve 1610 is provided so that it may be.

따라서 상기 배수밸브(1610)로 체크밸브(1600)에 남아 있는 물을 배수하여 배관이 동파되는 것을 방지할 수 있다.Therefore, the water remaining in the check valve 1600 may be drained by the drain valve 1610 to prevent the pipe from freezing.
