본 고안은 수중모터펌프의 실시간 회전수(回佺數)와 회전방향(回佺方向)을 측정(測定)하기 위한 측정장치에 관한 것으로, 좀더 상세하게는 수중에서 운전되는 수중모터펌프(UnderWaterMoterPump)의 회전수와 회전방향을 측정하여 운전 초기나 또는 운전중 발생할 수 있는 이상현상 즉 과부하(過負荷)현상과 역방향운전(逆方向運佺)으로부터 수중모터펌프를 보호할 수 있는 수중모터펌프의 실시간 회전수 및 회전방향 측정장치에 관한 것이다.The present invention relates to a measuring device for measuring the real-time rotational speed and the rotation direction of the submersible motor pump, and more specifically, the submersible motor pump (UnderWaterMoterPump) The real time of the submersible motor pump which can protect the submersible motor pump from abnormal phenomenon, ie overload and reverse operation by measuring the number of revolutions and the direction of rotation. It relates to a rotation speed and a rotation direction measuring device.

기존의 알려진 측정방법으로는 직접적으로 모터펌프에 적용하는 예는 없었으며, 실험용으로 로터리 엔코더를 설치하여 회전수 및 회전방향을 측정하여 왔다.There are no known measurement methods applied directly to the motor pump, and the rotary encoder and the rotational direction have been measured by installing a rotary encoder for experiment.

그런데 기존의 측정방법에서 사용하고 있는 로터리 엔코더 장치를 모터펌프에 설치하기 위해서는 회전자축(回戰子軸)에 직접 가공하거나 설치지그(jig=공작물)를 제작하기 위한 작업을 필요로 하였을 뿐만 아니라 회전자가 회전하면서 로터리 엔코더가 같이 회전을 함에 따라 설치작업을 잘못할 경우 이로 인한 설치구조물의 파손과 로터리 엔코더의 축정렬불량(軸整列不良)에 따른 축의 파손을 물론 회전자(回轉子)에 직접 부착되어 회전하기 때문에 이상한 소음(騷音)이 발생하는 문제가 있어 왔으며, 또 별도로 이와 같은 장치를 설치해야 하는 공간을 필요로 하는 어려움도 있어 왔다.However, in order to install the rotary encoder device used in the conventional measuring method in the motor pump, it was necessary not only to work directly on the rotor shaft or to manufacture the mounting jig (jig = workpiece) but also to rotate If the rotary encoder rotates together with the self-rotation and the installation work is wrong, the installation structure and the shaft damage due to the shaft misalignment of the rotary encoder will be attached directly to the rotor. There has been a problem that strange noise occurs due to the rotation, and there is also a difficulty in requiring a space for installing such a device separately.

또 다른 상검출 방법으로는 검출기를 이용한 방법이 사용되고 있으나, 이는 모터펌프의 회전방향(回佺方向)과는 무관하게 인입전원의 상방향(上方向)에만 검출이 가능하다는 단점을 지니고 있다.As another phase detection method, a method using a detector is used, but this method has a disadvantage in that it can be detected only in an upward direction of an incoming power source regardless of the rotation direction of the motor pump.

본 고안은 기존의 빈공간을 활용하는 한편 센서(Senser)의 고정장치에 따른 크기만 변경하면 기존의 수중모터펌프(Underwater Moter Pump)에 적은 비용으로 설치가 가능하고, 또한 수중모터펌프의 구조로 보아 회전하는 부분이 외부에서 보이지 아니할 뿐만 아니라 전동기의 중요한 기능인 전기적 에너지(傳奇的 Energy)를 회전 에너지(回轉 Energy)로 변환하는 과정을 실시간으로 확인가능 하기 때문에 모우터의 회전수(回佺數)를 통해서 슬립(Slip=유도전동기의 회전자 속도는 고정자(固定子)가 만드는 회전 자장에 대하여 반드시 얼마만큼의 시간적 지연이 있다. 이 지연(지연의 정도를 나타내는 것을 Slip이라고 한다)의 크기로 운전시의 이상을 분석(分析)할 수 있고, 또한 회전방향의 검출을 통해서는 역상운전(逆相運戰)으로 발생하는 기계적인 이상현상, 즉 임펠러(Impeller)의 풀림(역회전)으로 인한 파손 및 진동의 발생과 유량부족(油量不足)등의 요인을 조기에 제거하여 기기의 고장으로 인한 비용발생을 최소화하고 수중모터 펌프의 제어기술을 도모하고저 하는데 그 목적을 둔 것이다.The present invention utilizes the existing empty space and can be installed at a low cost in the existing underwater water pump by changing the size according to the fixing device of the sensor, and also has the structure of the underwater motor pump. The rotational speed of the motor is not only visible from the outside, but also the real-time process of converting electrical energy, which is an important function of the motor, into rotational energy, can be checked. Slip (Slip = Induction Motor's rotor speed must be a certain amount of time delay with respect to the rotating magnetic field produced by the stator.) The abnormality of time can be analyzed, and the detection of the direction of rotation allows the mechanical abnormality, i.e., the impeller, to be generated by reverse operation. Minimizes the cost incurred by equipment failure and promotes the control technology of submersible motor pumps by eliminating the factors such as breakage and vibration caused by loosening (reverse rotation) of the impeller and the lack of flow rate. The purpose is to do that.

A bearing which is covered with a cover to prevent it from going and is installed at both ends of the rotor to support the rotor and to rotate smoothly when the rotor rotates, and the outer ring of the bearing which supports the bearing and supports the rotor.

본 고안은 도 1 및 도2의 도시에서 보는 바와 같이, 수중모터펌프(P)의 내중심부에는 베어링(B) 커버(10)로 설치되어 전동기 회전자(20)를 가지는 회전자축(30)둘레에 서로 대칭을 이루는 방향에 센서(S1)(S2)(S3)(S4)를 고정하고 있는 센서고정테(40)가 상기 센서(S1)(S2)(S3)(S4)와 사이로 위치하는 고정보울트(50)(50´)(50˝)(50˝´)로 커버(10)상에 설치되며, 상기 센서중 3개의 센서(S2)(S3)(S4)는 회전방향으로, 그리고 나머지 1개의 센서(S1)는 기준위치감지부(60)에 회전용으로 각각 전원선(E1)(E2)(E3)(E4)으로 연결된 구조로서, 여기서 설명되지 아니한 부호 70 은 베어링 하우징, 90은 전원제어장치, 90은 칼럼파이프를 각각 표시한다.The present invention, as shown in Figures 1 and 2, the inner center of the submersible motor pump (P) is installed as a bearing (B) cover 10, the rotor shaft 30 having an electric motor rotor (20) around The sensor fixing frame 40 fixing the sensor S 1 (S 2 ) (S 3 ) (S 4 ) in a symmetrical direction to the sensor S 1 (S 2 ) (S 3 ) ( S 4 ), which is installed on the cover 10 with a high information bolt 50, 50 ′ (50 ˝) (50 ′ ′) interposed therebetween, and three sensors S 2 (S 3 ) ( S 4 ) is connected in the direction of rotation, and the other one sensor S 1 is connected to the reference position detecting unit 60 by a power line E 1 (E 2 ) (E 3 ) (E 4 ), respectively. As a structure, reference numeral 70, which is not described herein, denotes a bearing housing, 90 denotes a power supply controller, and 90 denotes a column pipe.

이와 같이 구성된 본 고안은 전동기의 초기 회전시 회전방향을 감지판별하고, 정상 운전시에 전동기에 회전속도를 감지 측정하는 장치로서 그 작용을 설명한다.The present invention constructed as described above detects the rotational direction at the initial rotation of the motor and detects the rotational speed of the motor in normal operation, and describes its operation.

회전자축(30)의 크기에 따라 센서(S1)(S2)(S3)(S4)를 고정할 수 있는 센서고정테(40)로 상기 센서(S1)(S2)(S3)(S4)를 베어링(B)커버(10)상에 90˚도 간격으로 서로 대칭 방향에 설치하되, 상기 센서고정테(40)는 센서(S1)(S2)(S3)(S4)와 사이로 역시 서로 대칭방향에 4개의 보울트(50)(50´)(50˝)(50˝´)로 고정하고, 상기 회전자축(30)에는 기준 위치를 표시하는 기준위치감지부(60)에 의하여 회전자(20)의 회전축(30)이 회전시 기준점을 알려주는 역할을 담당한다.Depending on the size of the rotor shaft (30) sensors (S 1) (S 2) (S 3) (S 4), the sensors in the sensor fixing rim (40) capable of fixing the (S 1) (S 2) (S 3 ) (S 4 ) are installed on the bearing (B) cover 10 in a symmetrical direction to each other at intervals of 90 °, the sensor fixing frame 40 is a sensor (S 1 ) (S 2 ) (S 3 ) (S 4 ) and between the four bolts 50, 50 ', 50' (50 ') (50'') in the symmetrical direction between each other, and the reference position detecting unit displaying a reference position on the rotor shaft 30. By 60, the rotation axis 30 of the rotor 20 serves to inform the reference point during the rotation.

따라서 설치된 센서(S1)(S2)(S3)(S4)와 기준위치감지부(60)와의 거리는 3~4㎜되도록 거리를 조정하여 줌이 가장 바람직하다.Therefore, the distance between the installed sensor (S 1 ) (S 2 ) (S 3 ) (S 4 ) and the reference position detecting unit 60 is adjusted to a distance of 3 to 4 mm, and zoom is most preferable.

이와 같은 본 고안에 있어서, 회전방향의 측정 원리는 전동기 회전자(20)의 회전자축(30)이 회전하게 되면, 기준위치감지부(60)가 회전을 하게 되고, 이때 기준위치감지부(60)가 감지센서(S1)를 지나서 감지센서(S2)를 지나게 되면, 이때 전원제어장치(80)는 상기의 감지센서(S1)(S2)의 신호를 분석(分析)하고, 정회전(正回輾) 여부를 판단하여 정방향출력신호(正方向出力信互)를 내보내게 된다.In this invention, the measurement principle of the rotation direction is that when the rotor shaft 30 of the motor rotor 20 is rotated, the reference position detection unit 60 is rotated, the reference position detection unit 60 When passing through the detection sensor (S 1 ) and passing through the detection sensor (S 2 ), the power controller 80 analyzes the signal of the detection sensor (S 1 ) (S 2 ), and It judges whether it rotates or not and outputs a forward output signal.

그리고 회전수의 측정원리는 전동기의 회전자(20)가 회전자축(30)을 중심으 로 정방향으로 정상적인 운전에 돌입한 후에 동작하게 되는데, 이는 전동기의 회전자(20)가 회전시에 기준위치감지부(60)가 감지센서(S4)를 지날때는 이를 전원제어장치(80)의 펄스카운터를 이용하여 회전수를 계수표시(計數表示)하게 되는 것이다.In addition, the measuring principle of the rotation speed is operated after the rotor 20 of the motor enters the normal operation in the forward direction about the rotor shaft 30, which is a reference position when the rotor 20 of the motor rotates. When the detection unit 60 passes through the detection sensor S 4 , the number of revolutions is counted using the pulse counter of the power supply control device 80.

이와 같이 수중모터펌프를 운전할 때 이의 회전수와 회전방향의 측정을 가능케 하는 본 고안의 전동기 회전자(20)는 이와 같이 회전하는 회전자축(30)에 의해 회전자(20)를 보호하기 위해 베어링(B)의 외륜이 움직이지 못하도록 베어링 하우징(70)에 고정되는 커버(10)에 의해 운전시 이물질이 들어가지 않도록 고정 지지되어 있어서, 구조물의 파손과 엔코더의 축정열불량으로 인해 발생할 수 있는 회전축의 고장을 방지할 수 있다.As described above, the motor rotor 20 of the present invention, which enables the measurement of the number of revolutions and the direction of rotation when the submersible motor pump is operated, has a bearing for protecting the rotor 20 by the rotating rotor shaft 30. (B) is supported by the cover 10 is fixed to the bearing housing 70 to prevent the outer ring from moving so that foreign matter does not enter during operation, the rotating shaft that may occur due to breakage of the structure and poor alignment of the encoder Can prevent the malfunction.
