운전중 베어링 토크 감시가 가능한 터빈 발전기 시스템Turbine generator system for monitoring bearing torque during operation
본 발명은 운전중 베어링 토크 감시가 가능한 터빈 발전기 시스템에 관한 것으로, 더욱 상세하게는 터빈 발전기 시스템에 로드셀을 장착하고, 로드셀에서 측정되는 값을 이용해 구동중인 터빈 발전기의 토크값을 계산하여 이를 실시간으로 확인할 수 있으며, 로드셀에서 측정된 토크값이 설정된 기준치를 초과한 경우에는 경보음을 발생시켜 관리자에게 알리는 기능이 부가된 토크 측정이 가능한 터빈 발전기 시스템에 관한 것이다.The present invention relates to a turbine generator system capable of monitoring the bearing torque during operation, and more particularly, a load cell is mounted on the turbine generator system, and the torque value of the driving turbine generator is calculated in real time using the value measured in the load cell. The present invention relates to a turbine generator system capable of measuring torque with a function of informing an administrator by generating an alarm sound when a torque value measured in a load cell exceeds a set reference value.
일반적으로, 터빈은 물, 가스, 증기 등의 유체가 가지는 에너지를 유용한 기계적 일로 변화시키는 기계 또는 장치를 말하며, 회전운동을 하는 것이 특징이다. In general, a turbine refers to a machine or apparatus that converts energy of a fluid such as water, gas, steam, etc. into useful mechanical work, and is characterized by rotational motion.
터빈의 회전 운동 시에는 규정된 토크에 맞게 진행되는 것이 바람직하지만 각종 변수에 따라 동작 시 토크가 달라질 수 있으므로 토크의 측정은 필수적인 요소라 할 수 있을 것이다.It is preferable to proceed according to the prescribed torque during the rotational motion of the turbine, but the torque measurement may be an essential element since the torque may vary during operation depending on various variables.
종래의 토크 측정 방법은, 터빈 오버훌 시 즉, 터빈을 완전히 해체하여 정비 점검 할 때에만 가능했다.The conventional torque measuring method was possible only when the turbine overflowed, that is, when the turbine was completely dismantled for maintenance inspection.
터빈에 베어링을 조립하기 전에 베어링만 조립하여 인위적으로 토크를 발생시킬수 있는 치구를 베어링에 부착하여 그 치구를 움직이는 힘을 설정된 토크값에 맞도록 체결볼트의 조임 정도를 조절한 후에 다시 베어링을 해체하여 터빈을 조립하고 조절된 체결력으로 베어링을 다시 조립하는 방법이 사용되었다.Before assembling the bearing to the turbine, attach the jig that can assemble only the bearing and artificially generate torque to the bearing, adjust the tightening bolt tightening force to adjust the force to move the jig to the set torque value, and then disassemble the bearing. A method of assembling the turbine and reassembling the bearings with controlled clamping force was used.
하지만 이러한 종래의 기술에 따라 토크를 측정하기 위해서 터빈을 완전 해체하는데에는 많은 시간과 인력이 소모되었기 때문에 토크를 측정하는데에 있어 많은 어려움이 따랐으며, 이를 개선하기 위한 발명이 대한민국등록특허공보 제10-122093호에 제시되어 있다. However, according to the conventional technology, since it took a lot of time and manpower to completely dismantle the turbine in order to measure the torque, many difficulties were involved in measuring the torque. Presented in -122093.

A power lock coupling 400 positioned on the line and coupled to rotate in association with the rotation shaft of the air turbine starter; And an adapter coupled to the gas turbine engine and the air turbine starter, in which the first shaft 100, the second shaft 200, the torque meter 300, and the power lock coupling 400 are installed. 500);

하지만, 종래의 기술에 따르면 토크측정기(300)의 설치를 위한 구조가 복잡하며, 에어터빈시동기과 상기 가스터빈엔진의 회전축의 사이에 설치되어야 하기 때문에 터빈 장치의 제작 후에 토크측정기(300)의 장착이 불가능하며, 터빈 장치의 제작을 진행할 때에 토크측정기(300)의 설치가 미리 이루어져야 하는 단점이 있다.However, according to the related art, the structure for the installation of the torque measuring device 300 is complicated, and the mounting of the torque measuring device 300 after the manufacture of the turbine device is required because it must be installed between the air turbine starter and the rotary shaft of the gas turbine engine. Impossible, there is a disadvantage that the installation of the torque measuring device 300 must be made in advance when manufacturing the turbine device.

도면에는 편의상 한쪽의 볼트체결부(11a-1)와 그에 체결되는 부품들만 표기하였으나, 다른 한쪽에 형성된 볼트체결부(11a-1)에도 동일한 구성이 조립된다.In the drawings, only one bolt fastening portion 11a-1 and parts fastened thereto are shown for convenience, but the same configuration is assembled to the bolt fastening portion 11a-1 formed on the other side.
도 6을 참조하면, 회전축(20)과 지지부(21) 및 고정판(11)의 볼트체결부(11a-1)의 상측면은 모두 대체적으로 평행한 형태로 장착되어 구동이 시작된다.Referring to FIG. 6, all of the upper surfaces of the rotating shaft 20, the support part 21, and the bolt fastening part 11a-1 of the fixing plate 11 are mounted in a substantially parallel shape to start driving.
하지만 터빈 발전기가 구동함에 있어 발생하는 진동 및 그 밖의 원인에 의해 회전축(20)이 도 7 및 도 8과 같이 휘어지는 현상이 발생할 수 있다.However, the rotation shaft 20 may be bent as shown in FIGS. 7 and 8 due to vibration and other causes generated when the turbine generator is driven.
도 7을 참조하면, 회전축(20)이 고정부(11)의 상측에 표기된 화살표와 같이 시계 반대방향으로 휘어지게 될 때에는 회전축(20)을 감싸고 있는 베어링(10)이 회전축(20)과 함께 휘어지게 되고, 베어링(10)을 내부에 포함하는 고정부(11)에도 이 힘이 전달되게 된다. 따라서 고정부(11)를 고정하고 있는 제1볼트(14a) 및 제2볼트(14b)의 하측에 위치하는 제1로드셀(12a)과 제2로드셀(12b)에는 화살표와 같은 방향으로 힘이 가중되게 된다. 즉, 제1로드셀(12a)에는 기존보다 더 큰 힘이 가중되며, 제2로드셀(12b)에는 기존보다 적은 힘이 가중되게 된다. Referring to FIG. 7, when the rotating shaft 20 is bent counterclockwise as shown by an arrow marked on the upper side of the fixing portion 11, the bearing 10 surrounding the rotating shaft 20 is bent together with the rotating shaft 20. This force is also transmitted to the fixing part 11 including the bearing 10 therein. Therefore, a force is applied to the first load cell 12a and the second load cell 12b positioned below the first bolt 14a and the second bolt 14b which hold the fixing part 11 in the same direction as the arrow. Will be. That is, a greater force is applied to the first load cell 12a than the conventional one, and less force is applied to the second load cell 12b than the conventional one.
또한, 도 8을 참조하면, 회전축(20)이 고정부(11)의 상측에 표기된 화살표와 같이 시계방향으로 휘어지게 될 때에는 도면에 표기된 화살표와 같은 방향으로 힘이 가중되어 제1로드셀(12a)에는 기존보다 적은 힘이 가중되고, 제2로드셀(12b)에는 기존보다 더 큰 힘이 가중되게 된다.In addition, referring to FIG. 8, when the rotating shaft 20 is bent in the clockwise direction as shown by an arrow marked on the upper side of the fixing portion 11, the force is increased in the same direction as the arrow shown in the drawing to load the first load cell 12a. There is less force than the conventional, and the second load cell 12b is weighted more than the existing.
따라서 회전축(20)의 휘어지는 정도는 제1로드셀(12a)과 제2로드셀(12b)을 통해 측정되는 토크값이 초기에 세팅된 값에서 얼마나 변화하였는지 그 변화량을 실시간으로 측정하여 확인할 수 있다.Therefore, the degree of bending of the rotation shaft 20 can be confirmed by measuring the amount of change in real time how much the torque value measured through the first load cell 12a and the second load cell 12b has changed from the initially set value.
도 9에 도시된 바와 같이, 제1로드셀(12a) 및 제2로드셀(12b)에 계측된 값을 제1로드셀(12a) 및 제2로드셀(12b)과 전선을 통해 연결된 분석기(30)로 실시간으로 전송하게 되며, 분석기(30)에서는 전송된 값을 이용해 토크값을 계산하고 그 값의 변화량을 계산하여 회전축(20)의 휘어짐 정도의 분석이 지속적으로 진행되며 이는 분석기(30)와 연결된 모니터(40)를 이용해 수시로 확인할 수 있다. 또한 설정된 범위 값에서 벗어나는 값의 변화량이 측정될 시에는 분석기(30)에서 경보장치(50)로 신호를 보내 경보를 울려 관리자에게 현상황을 알리도록 한다.As shown in FIG. 9, the measured values of the first load cell 12a and the second load cell 12b are real-time to the analyzer 30 connected to the first load cell 12a and the second load cell 12b through wires. In this case, the analyzer 30 calculates a torque value using the transmitted value and calculates an amount of change in the value to continuously analyze the bending degree of the rotating shaft 20, which is a monitor connected to the analyzer 30 ( 40) can be checked from time to time. In addition, when the amount of change in the value out of the set range value is measured, the analyzer 30 sends a signal to the alarm device 50 to alert the administrator to the status quo.
